Nokia 5800 Lock Code Problem After Upgrade Firmware To v21.0.025

The latest Nokia 5800 device firmware was out in the earlier of April but only yesterday I had mood and free time to upgrade my touch touch baby.

Although the earlier firmware upgrade from v11 to v20 didn’t erase user data (e.g. contacts, notes, calendar entries, settings, etc), I made two copies of backup before flashing it with NSU (one backup to memory card by using the inbuilt backup function while another one save to my Vista SP1 Desktop via Nokia PC Suite).

Luckily I had done this; otherwise I might have to cry for a day :-).

Why? Because I was panic and went on to “format” the phone after found out the keypad to enter lock code is no longer default to alpha-numeric!

For those who have gone through the Nokia 5800 firmware update from v11 to v20 should know that the v20 presents an alpha-numeric keypad defaulted to alphabet input.

As the Nokia security code (a.k.a. lock code) is used to be numeric only so the new default touchscreen keypad poses difficulty to most users. The novice even find it a great challenge or a nasty glitch and complained about lock code not working or security code fails soon after upgrading to this v20 firmware.

Although I filed the same complaint, but I knew that it can be easily fixed in no time. What I did was to update the lock code from numeric to alphabet, using the first of three characters on each key. So for example, the lock code 23267 is then set to “adamp” :-)

However, this “fix” made me crazy as soon as the phone rebooting after the v21 update completed. Now the v21 presents a numeric keypad, no more alpha-numeric, to enter lock code or security code!

This round, patience and alert are not with me, totally out of control, as my other half urged me to go out on time for dinner with parent-in-law. Due to the pressure of time, I panic and decided to format the darn phone with three secret keys, even that kind of “factory restore” doesn’t reset the Nokia security code. Somehow, I did it and end up to lost those user-based data and settings. WTF!

After cooling down, I found out that actually I can press the # key continuously for few seconds to get back that freaking alpha-numeric keypad, in order to enter my valid lock code that made up of alphabet only. (Probably, this “shift” key might also works in the v20 keypad for entering lock code as well. Mind to leave a comment for answer of this?)

Now, I am not sure this round the v21 update does erase the settings, contacts, notes, calendar entries, etc, but I am certainly able to restore all those user-based settings and data from the backup in memory card, that made by Nokia 5800 backup function in the File Manager icon.

    Seems every one with nokia 5800 V20 has been complaining about this. You asked for a comment on holding the # key for a while to switch from alpha to numeric on V20. I can confirm that does indeed work. This looks like a simple keypad mode default on V20 and V21 has caused no end of grief for people…better documentation on switching keypad modes would have helped too.



  4. Walker 29-06-09@21:41

    Hi John, thank you for confirming this. I agree with you that Nokia should have made a note or changelog to tell people of the keyboard mode switching, which I personally think it’s important and worth to know.

  5. John Court 30-06-09@08:34

    Yes its one of those simple cases that probably wasn’t checked in testing and unfortuately will cause the classic “this thing is crap” response from first time users that get themselves tangled up. The solution is VERY simple for people. To re-iterate :

    1) On nokia 5800 V20 the lock code input defaults to alpha-numeric and the default code is unfortunately 12345. To input numeric simply hold the # key for a second or so and the keypad mode will change to numeric input. You will have to do this every time you input the lock code if you keep it numeric.

    2) On nokia 5800 V21 the lock code input was changed to default to numeric which will work fine for people who haven’t changed their lockcode to alpha but will bite anyone who has (i.e. those upgrading from V20 that managed to get the lockcode changed to an alpha). To change to alpha-numeric input again hold the # key for a second or so.

    Thanks Walker for your solution…it might be worth posting widely.

    So , what is the default CODE again? I know is not 12345…. I still having problem with this people… Please help …. Thanks again…

  7. John Court 01-07-09@04:47

    On my phone at V20 it was 12345 this was in Australia on the 3 network …. on V21 I can’t say yet if they changed the default (the nokia ovi site isn’t letting me complete the firmware download of V21 and locks up at 97MB every time !!)…. for your circumstances I suspect it will depend on what has been done to the phone by your carrier and yourself. What version are you running and have you or some care centre changed the lock code at some point ? The amount of noise I am hearing I guess it is also possible that some well meaning telco changed the lock code to something that might work on V20 in alpha mode … the 1 key doesn’t so it could be something like 2345 however be aware that if they did this it could have been changed to alpha numeric “adgk”. Unfortunately without knowing your specific devices history and firmware revisions and network its unlikely that anyone but your telco can help. Thats the thing with security once things get out of control the only way to bring them back is often a factory default reset.

    Sorry I can’t be of more help.

    Hi guys im gona buy nokia 5800. Nagagandahan kasi ako. But should i upgrade to v21 firmware? For what purpose is this? Just to make many apps on phone?
    Pls answer me guys. Sorry for ignorance but i wana learn! TIA.

  9. Walker 01-07-09@21:39

    Suppose an enhancement.

    Just an update on the V21 upgrade … I managed to get that for my 5800 yesterday and it did NOT change my lock code (i.e. I could still use the original numeric one I had set in V20) so that is a good thing for those upgrading provided you make sure you KNOW what your original code is and set the keyboard input mode appropriately.

    Mia, on the V21 vs V20 I have noticed two things that were important to me. Firstly the lock code keyboard now defaults to numeric input, this is nice since I no longer have to hold the # key before entering my lock code but not really a big deal. Secondly I have found the browser no longer locks up or is as slow on some fairly large and dynamic web pages that I visit regularly. There are also mention in the release notes that they improved the touch pad accuracy/response. In all I haven’t seen a downside to the V21 yet. As a precaution before upgrading ALWAYS do a full backup of the device first via Ovi Suite on your PC and I made sure I turned off the lock code feature during upgrade just in case things went wrong (i.e. since you have to enter the lock code to turn on/off lock code feature activation in settings it means after upgrade the worst that could happen would be you couldn’t turn it back to auto locking compared to not being able to get into the phone at all if the feature is left on during upgrade).

  20. peter 17-02-10@15:20

    Thanks for the info, you saved me.
    I had a alphabetic lock code and after I updated from version 20 to 31.0.101 I could not enter the code as the keys for entering the lock code after firmware update were numeric only. Reset does not reset the code and I was really stuck.
    Holding # was the answer but no indication on the screen that # does that or in the user manual.
    Not good Nokia !!!
