How To Fix Nokia 5800 Expired Certificate Error During SIS Installation?

For past few days, I’d been busy finding workable solution to the annoyed “expired certificate” problem that happen when I attempt to install SIS/SISX program files in Nokia 5800.

The Google result suggests me to reset the date of phone to be earlier or later than current date, format the phone with *#7370# secret key followed by changing the phone regional settings to other countries (UK, HK, etc), set “Online Certificate Check” to off, etc.

There are forums and blogs mentioned that the version 10 firmware is well known for this “expired certificate” bug and thus should upgrade to the latest firmware version 11.0.008.

However, my Nokia 5800 firmware is already at this latest version out of the box. So, what’s next?

After trying with so many suggestions from Google search result to no success, I almost give up repeating the *#7370# formatting process and thought of calling up Nokia Care Centre to tell them this Nokia 5800 is a crap!

Next, to add yet another record in my Nokia 5800 defects sheet :-(

But now, I’m pleased to tell you that I’ve fixed this “silly bug” at last try, with the help of a China blogger who reply me in just one simple line – remove the bundled microSD card and format the phone with *#7370# secret key!

How to solve the Nokia 5800 “Expired Certificate” error that fails most SIS program files installation?

To be frank, I just don’t believe that one-line reply could be a real solution for me. But, I’ve ran out of ideas and found nothing newer than his suggestion.

So, I simply take it as last resource to try. Eventually, this simple trick does works magically, and I can’t wait to tell him how excited and grateful I am!

For reference, here is the solution in detail (in case you’re not sure what additional steps I’d done on top of his one-line guide):

Backup all messages, notes, calendar entries, and contacts.

I used Nokia PC Suite to backup all these four components instead of using Nokia 5800 inbuilt backup function, which doesn’t has an option to backup Notes (but I’m not sure the ALL settings will back up the Notes).

Remove the microSD memory card.

When the phone is powered on, don’t simply remove the memory card. Otherwise, the memory card content will likely corrupt.

To remove the microSD card when the Nokia 5800 is switched on, press the power key (the button next to the power charging port), scroll down to locate and select Remove Memory Card, opt “Yes” as the “Removing memory card will close all open applications. Remove anyway?” message is displayed.

Shortly after, the “Remove Memory Card and press OK” message appears, and then the microSD is ready to be unplugged or removed from the dedicated slot.

Notes, both SIM card and microSD card slot are next to each other on the same side (another defect, personally), don’t be careless and end up corrupting the SIM card (if you happen remove SIM card instead of microSD card).

Format the Nokia 5800

Access to touch keypad and enter *#7370# secret code (not so secret, anyway) to restore phone settings to factory default (even the user data and files are deleted).

Next, you’re prompted to enter the Nokia phone lock code. The default is 12345, if this code hasn’t been changed by yourself or any one.

Then, the phone restarts and you’ve to select the country region (just select your own country from the list, in this case), followed by request to enter current date and time.

When the phone is ready, power it off again to re-insert the memory card (for highly safety measure, unless there are nothing important kept in the memory card, e.g. picture, music, documents, etc).

As the phone is switched on again with memory card inserted, the “preparing memory card” message appears.

Finally, I’m happy to be able install all my wanted Nokia 5800 programs and games without getting the “Expired Certificate” error message that says “Certificate may not yet be valid, is expired or phone’s date setting may be incorrect” :-)

Kaushal February 3rd, 2009 3:04 PM

Hi, I am from India, I read the tutorial in detail, But what about nearly 250 original songs and their licenses? how can I back that up, as after formatting, as I am told, the licenses will not work!!!!!! Please reply!
maria nelia February 3rd, 2009 3:17 PM

thanks to you it works!
Walker February 3rd, 2009 8:18 PM

Ni Kaushal, are those 250 songs kept in microSD memory card or phone memory?

As for My Nokia 5800, there is no special “license” bundled or songs kept in phone memory. So, I couldn’t answer your question. Sorry.
Sorin Calinescu February 3rd, 2009 8:43 PM

I thank you honestly for your precious help!!!!

I was thinking to resell my 5800XM, because of that error… but, thanks to you, now I’m happy with my phone again!!!

Chaz February 8th, 2009 1:01 PM

I have activated the free 3 months of drive and walk with nokia maps, could you please tell me whether formatting the phone will effect this?
sanjeev bathinda. punjab. india February 8th, 2009 4:15 PM

No. I’ve tried many times and with a bit variations, but didn’t succeed.

I don’t understand how the above people succeeded with this method.
Walker February 8th, 2009 5:34 PM

Hi Chaz, I haven’t activated the 3 months free walk and drive feature so I can’t answer this.

If you’re adventurous, just do it and see if you could reactivate it by going to Nokia Maps > Option > Extra > Option > Enter License Code.

Otherwise, just wait for 3 months (by then, Nokia Device Software Update should have a solution to fix the “expired certificate” problem) :-)

Hi sanjeev, I’m not sure what happen to your phone. sorry I can’t help.
vga February 9th, 2009 4:41 AM

Dave February 10th, 2009 6:22 AM

Lokesh February 11th, 2009 3:46 AM

hey buddy,
during formatting i forgot to remove memory card.. :(
so after formatting my card is working fine but problem is still there…
also i did backup the data on pc but now it is not getting imported to my phone…
help me out please…
Walker February 11th, 2009 9:52 PM

Not sure what is the cause that you couldn’t restore backup back to the phone.
gk007 February 14th, 2009 6:24 PM

Thanks!! This worked brilliantly, before the .sis files that hadn’t even expired didn’t work (I checked them using SISWare), now they do!!

Thank You so much!

you know what mate?! you are a legend big time

nice one for that :-)
Lokesh February 16th, 2009 5:26 PM

Fortunately i also backed up all data on phone itself,so got all the contacts back…. :)
but certificate problem is still there…
may be next time it gets sorted out….
Ash February 16th, 2009 8:40 PM

Excellent – works. Google maps is far better than the installed app.

Thank you.
Alvin Chin February 18th, 2009 5:53 PM

i m feeling very disappointed about what happen on 5800—”expired certificate”….
this is what i just face since the 1st day i’m try using 7610, n70, n73, 6110, n95, n96…
nokia should notified all user to send back those sold out hand phone and reinstall the “normal” software version for all user, else who will buy it in future???
Christian February 18th, 2009 6:21 PM

TCzzz March 13th, 2009 3:25 AM

Well after hours of searching the web and seeing many solutions for this,it seems i found one that worked.
Although i didn’t try the others i saw since they didn’t look too confident about how they did it and the final result.
But with you post and great detail i tried what you said and didn’t have one problem.First time worked great.
I intended to install googlemaps and that’s why i got the error in the first place.Now although on map install it said not compatible i continued anyway and it at the moment seems too work without issue.

Thanks for the great post.

P.S
One little note you have copyright on you heading,would it be possible too ask your permission to post this info with full credit too you at a couple of forums i belong too.
I know i could just do it anyway and you probably never know but out of respect for the great post i thought i would ask.
NAjm March 13th, 2009 11:05 AM

hi,

Thanks for the information but i am still getting cert expired error while installing any softwares.

prevously my version wa 20.x.x and after the format it is 11.x.x even though it is not working……………………..please let me know for any further inputs.

Thanks in advance
Walker March 15th, 2009 10:07 PM

@TCzzz, thanks for your notice and this is a note for you and all others who would like to do the same:

If you ever like to see Google returns more than 1 search results of same content that appears in multiple domains, and never feel sick, please do so.

Otherwise, please be kind to put a reference link back to original post, in addition to your own style of writing to describe the same technique in a better way.

Those who are familiar with my writing know that my way of explaination is suck. If you simply copy and paste, it make you suck as well.

P/S:
I never thought of putting the “copyright” word until this silly bug that really really upset me:

thanks for the reply.i have taken notice of what you said and made my on easy 5 step detail on how to fix the cert error and posted it where i intended with a credit to you and a direct link back to this post.

I’m new to nokia guys,tell me if 12345 unlock code works.The pad doesn’t register 1 all the rest of the pad numbers work,example;abc2,or def3,etc.Then after five attempts it says 5 incorrect attempts will unlock in 5 minutes!All this happens after I press secret code*#7370#.I’m sure I didn’t enter any phone locking when I bought the phone,only sim card.Anyone can please help?
TCzzz April 1st, 2009 8:54 AM

@louis
It works fine if for some reason after your format the 12345 didnt work try 00000 instead.
Dont know why 1-5 wont work since thats the default code and since the phone been formatted that would be the code too use.

wiebenik April 4th, 2009 7:13 AM

Werkte eerst niet: ik kon de code 12345 niet intikken omdat toets 1 niet reageert! Ik had hetzelfde probleem als Louis een paar dagen geleden beschreef.
Echter, daarna probeerde ik het helemaal opnieuw. Maar nu hield ik de toets 1 lang ingedrukt: en dat werkte prima!!!!!
DUS: toets 1 lang ingedrukt houden indien niet meteen een 1 verschijnt.

Nu heb ik eindelijk google maps. Yoepie

**** Edited: Google translated:

Not worked, I could not type the code 12345 as test 1 is not
respond! I had the same problem as Louis a few days ago
described.
But then I tried it all again. But now I was
1 key pressed long: and that worked great !!!!!
So long press button 1 if not January 1 appears.

Now I finally google maps. Yoepie

For those who are running latest firmware v20.x, beware that the “software keypad” to enter lock code is alpha-numeric.
Louis April 7th, 2009 4:31 AM

What if I go to settings, phone, phone management, factory reset?
It won’t explode, no? Could that work as in resetting?
Thanks nice people.

Hi
i did as you told, but i stil can’t install ths sis file
it’s say’s “unable to open. file type not supported”
it’s a GPS program “sygic 7.6″ if you…

is there any other way to instal it ? or may be other GPS program you suggest ?

i’m from israel if it’s matter ..

10x
Walker May 10th, 2009 12:35 PM

@Jeni, that error is not related to this topic.

Nokia 5800 is running Symbian OS S60 5th Edition UI and thus some of the S60 3rd edition application might not able to run or install on this platform.

If that is the S60 5th Edition compatible SIS file, that might be a corrupted file?!

Tnx man. ;)
Chameng June 1st, 2009 4:57 PM

@yash, Nokia phones are market dependent. If you bought your 5800XM from the Philippines then ver21.0.025 won’t really work for you. You have to wait coz there’s a coming version just right for your phone. In the meantime, do the *#7370# first so it will go back to your original firmware version.
Flavier K. South Africa. June 3rd, 2009 8:55 PM

A SOLUTION WITHOUT RESET/FORMAT OR WHATEVER.
This is a 30 SECOND SOLUTION SO FAR BY MAGIC.

-Change your date NOT BACKWARD but FORWARD.
For me it was on 1 june 2009 and I changed it to 1 june 2010.
And believe me there was a pub for 2010 Fida WorldCup in SA
On TV And by some how the stupid “expired certificate” message
Is no longer there. I can install all compatible app on my
Nokia 5800 even when restored my date to normal I can still install
ALL Compatible: ovi store app, google map, fring, nubizz … All.

IF YOU GOT RESULT JUST COMMENT A THANK TO ME AND I
WILL APPRICIATE-

mim June 15th, 2009 10:19 PM

hi – i’m wondering will i lose the latest update of my phone, if i hard reset my phone the way you explained in your post?
reason i’m asking is: the update isn’t yet available online in my country, or by my network provider so it’s been quite a hassle to find a nokia care shop and wait for them to install it.
Walker June 16th, 2009 4:38 AM

The phone will still running the same firmware, e.g. v21, even after doing a hard reset on the phone.

Hi,
I bought the phone from a O2. This phone was locked so that can’t be used in any other country. But i unlocked the phone so i was able to use in Pakistan. Now if i reset my phone, will it be again locked or will work fine??
And the last thing I have version 11.x . Will it be lost after the reset or remains updated.

Waiting for your response WALKER.
Thanks
Walker June 21st, 2009 2:57 PM

The format code will not wipe out the software version, but I can’t confirm about the lock code (I think it won’t).

hey it worked once i followed the 5 step process… but later on it is again givin the same expired certificate error…. wat to do… do some one know wat to do pls lemme know…. shd i again follow the same process (which is actually a pain to do every single time i wanna install some app)….
Simon July 20th, 2009 3:49 AM

This didnt work for me at all. I have followed these instructions to the letter twice now with no success. First time i was on firmware version 20.0.012, then i updated my phone, tested if that fixed the problem on its own, it didnt. Then i tried these instruction again on the new firmware version (21.0.025) with no luck. I appreciate the time you put into this and it has obviously helped a great many people but does anyone know what else i could try to fix this problem?

Regards

Simon

I still have problem with certification … If I chose restore data from PC suite app does it restore and old certification ?
Thanks
Walker September 29th, 2009 2:05 AM

@mehek, I think your download problem is a separate issue (maybe the link is broken or connection problem?)

@Slax, I don’t think so.
Slax September 29th, 2009 2:23 AM

I must select region Hong Kong or UK or I can chose my own ?
In 1st try I was chose my own :S maybe that’s a problem ?!
Slax September 29th, 2009 6:15 AM

I didn’t make it with Hong Kong and UK :S
Mohit October 2nd, 2009 7:34 AM

This method Is exclusively for Nokia 5800xm….

first of all I need to say some thing….. “This is a F.W bug……And I hope nokia will fix this bug in a month”

Exclusive Method:
=============
people you need signed applications(nokia 5800 compatible Appz)

1) Make your phone memory backup data using nokia pc suit 7.1(very important)
2) After that remove your Micro sd card from mobile..
3) Remove your SIM card also(very important)
4) press *#7370# and unlock code to format your phone memory(yap.. this is safe default is 12345)
5) You will lose all your important date with this action…so make a backup of your phone memory
6) Now nokia 5800 xm will reboot…..wait for a minute….
7) Then select your country region as “Hong Kong”
Set the current time……(set your phone to offline mode)_
9) Now you can put that Micro sd card ……
10) And don;t insert that SIm card right now…just wait….and try to install any .sis file
11) And Volla…u may install any singed application ……
12) After that just install your Sim Card…..
13)Chng settings back 2 ur region

Hope this will make nokia 5800xm owners happy……..

THIS WORKS FOR ME !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
SMC October 3rd, 2009 8:03 AM

does this wipe off all the default applications of your nokia 5800 or just restore default settings? thanks!
Colorman October 3rd, 2009 10:15 AM

Man YOU ARE THE BEST!!!!!

Thanks so much!

Finally i could install acrobat!!!

I works fine your procedure on 5800 @ version 20.2.014
Walker October 3rd, 2009 11:55 PM

@SMC, it will not wipe off the default apps bundled with the firmware installed but it does reset all settings to the default of the firmware.
mullo October 4th, 2009 2:17 AM

This didn´t work at all. I still get this f…ing “cert error” message when installing .sis-files.

LubomirXM November 2nd, 2009 10:51 PM

I expierenced this problem too just today…i had to hard reset my phone yesterday because of a homescreen problem…and then i restored everything from the backup but still had to install some things so i did and I saw this error “expired certificate” and i did what u told us to do and now it shows me on the same apps another error “certificate may not yet be valid,is expired or phone’s date setting may be incorrect” what to do now… ?

P.S.:these are the same files that fitted perfectly previously on my phone
LubomirXM November 2nd, 2009 11:11 PM

a little edit….i just had an “expired sertificate” error while now and now i got that longer error :P
LubomirXM November 3rd, 2009 3:52 AM

ok now…………. i`m pissed….:
1st.i updated the ****in firmware to the latest version
2nd.I formated the card
3rd.I reseted the phone AGAIN and i stil lget the error….I`m making a sertificate and it still doesn’t work….please guys…help me
LubomirXM November 3rd, 2009 4:16 AM

ok i did it….ha ! finaly and here is how it worked with me…

if there is nothing more u can do just go to the app u need to install–>options–>scroll down to Details–>File

then look at the date at the bottom and make the calendar one day before that…for example the app is on 10/30/2009 and u make the calendar on 10/29/2009.But this is only if u get the full msg “certificate may not yet be valid,is expired or phone’s date setting may be incorrect”
LubomirXM November 3rd, 2009 5:21 AM

hmmm with some apps it doesnt work but without checking each date almost every each was succesful with 29 oct. 2009 and some with 12oct.2009

In UK Nokia now giving Maps system totally free but I suggest format phone first as above then reload latest software through PC Suite.

New maps much better than previous ones.

Get the link to free maps from Nokia site.I understand they will be installed with all new nokia smartphones from March.
stefika993 February 15th, 2010 11:53 PM

I tried 12345 and nothing…. is there any solutions?
stefika993 February 16th, 2010 12:27 AM

solution found…. for 5800 that have software version v20 or newer:
1. power off the fone
2. press and hold green, red and camera (for taking photos) button and press the power button until it gives sings of life xD
3. just pick everything it needs and thats all, you’re not prompter for any passwords and stuffs….

ps dont be an idiot like me to forget to backup contacks ;)

everuthing done but still have the same problem while instaling application – in this case shakesms…. help psl

Ninja March 18th, 2010 12:13 PM

i think i understood what the problem was.
it seems that after the format if the phone updates the date and time from the operator then the bug reappears. Therefore what i did was i removed the sim card. formatted the phone and then disabled the auto update of the date and time. After that i inserted the sim card. Now all applications can be installed and i love my phone.

@chinmay:

Your software will still be of V 50.0 even after update. You dont have to update again

Its a problem with acquiring DATE AND TIME UPDATE FROM THE NETWORK.phone shows wrong time and date when phone is restarted.even when changed to correct time ,certificate error persist,looks like nokia has some other clock running !!

SOLUTION:Just try some another SIM card,if it acquires correct date and time from the network PROBLEM IS 100% SOLVED no need to format at all……

yama July 24th, 2010 5:36 PM

dear friend as you said I do that but still my nokia 5800 show that error “expired certificate” please once again shortly direct me how to fix it. thanks
tillu July 26th, 2010 1:05 PM

Upgrade your firmware,its a major bug in nokia..
changing sim card which can retrieve correct date and time from network works 100%.you have to set correct time first and then restart with automatic time update enabled.
Meedan July 27th, 2010 8:57 PM

Hi,

I have Nokia 5233 v21.1.004 – I had updated my software by dialling *#0000# – then options Update software.

i have tried all the methods given in this post & replies, changing date, chaning country to Honk kong,europe,UK. I removed me SIM Card, formatted the phone tried to install without SIM Card, tried with 3 different SIM Cards & 3 different Memory card. have spend almost 5 hours continiously for this bug but everything in vain. Search entire google & tried almost 50 different methods given all around the web. but nothing worked for me. Formatted my mobile almost 20 times with soft reset, hard reset but all in vain. I have purchased it recently or else I would have thrown this shit.

if still any genius know some other method which really works do let me know.

hi thank you finally works. you are the best
Some Guy August 11th, 2010 11:31 AM

I’ve tried this and every other crack-pot fix. None of these ideas makes any sense or actually works. All it does is waste more time. Do yourself a favor and never buy Nokia crap. It’s always the same, never works properly.

i think i understood what the problem was.
it seems that after the format if the phone updates the date and time from the operator then the bug reappears. Therefore what i did was i removed the sim card. formatted the phone and then disabled the auto update of the date and time. After that i inserted the sim card. Now all applications can be installed and i love my phone.

This guy is saying the same thing what i said…..
this trick works man!! try it…..

…and thankyou for the people who appreciated me………
Arief Hussein August 21st, 2010 4:32 PM

Arief.
