[N8Belle]

I don't know if this helps. Apparently, the security code is the same as the SIM2 PIN. For me, I had setup the SIM2 PIN to be the same as the SIM PIN, which was a four digit number. I then entered it when requested the security code, and it worked... never bugged me anymore!!
NB: Better setup your security code to something memorable. I used my surname (via alpha numeric) to construct a memorable security code. For example, if your name is PETER then you could use 73837, which corresponds with PETER in alphanumeric form!! I hope this helps!!

Try 0000  for nokia Belle

[kamran859]

i tried to update my nokia n8 software to Belle, in phase 3 on 15% of installation phone restartsand then it gives me a message on the nokia suite that 'lost connection' and then the phone restarts when i close it, in the end it shows an 'error code 12052'  on nokia suit. 

i have no idea what to do, i tried to restart while the phone is connected to the laptop, i even dc the phone and restarted and again connected, and try to run the installation again, but still was not able to update belle on my phone.

The best part is that there is no way i can email nokia about this issue directly. there is no such way. so dont know what to do....

very funny, I've tried long ago, but this is not the solution

[ghaikal]

when is the solution NOKIA !!! 

[DarkAngel0666]

just updated my n8 with belle, and besides the improved apperence, a simpler menu, and some features looked like android, i must saddly say that for the 1 time i'm very disappointed with nokia. Don't understand why this software wasn't released since the bigining with n8 at least, and why there's so many bugs on it. My n8 restarts and locks several times when i'm using it, doesn't matter if i'm playing or calling someone or simply adding or removing widgets, the browser is incredibly slow, don't know if anybody else has this issues aswell, fortunatly don't have the issue of the security code. I made a copy from all the files and folders of the phone before update on my laptop and will try to replace this new ones with the old ones and try to get old software back, if doesn't work and can't use phone anymore, i will have no choice and will by an iphone and not going to by anymore nokias especially because i don't like windows software in pnones or pcs and will say good by to nokia forever. Hope nokia sorts all our issues soon.

I have same problem with my nokia n8 upgraded in Uk. so nokia can build a software and not solve a tiny problem like code error. Been 8 yrs loyal to nokia but iphone here i come...

FOR SURE, THE SECURITY CODE AFTER UPDATE IS THE PASSWORD OF YOUR OVI STORE.

i had never used f-secure but was reading through trying to find a security code cos i kept getting code error i went into f-secure and did as it said and i was able to use my own security code no longet get code error

Seems like I (almost) forgot that I had set a security code before my upgrade from Anna to Belle. After the upgrade, I was asked for a security code and then I couldn't remember it. I was very frustrated, and thought there was something wrong with Belle. The good news is that after reading through these forums, I realized that there was nothing wrong with Belle and then I remembered the code. After entering it, my security settings work fine. However, the reason why I needed the code in the first place, was that I don't particularly like Belle and I decided to downgrade back to Anna. My main reason, is that I couldn't use that nice video calling app called Fring with Belle, and I loved that app. So, I am resetting my phone to factory defaults. Whether that will remove Belle, I don't know. Watch this space!

I've just call Nokia support.
Up to now there is no solution from Nokia and it seems that Nokia does not even understand the problem.
We cannot change the SIM because any protection code fails.
We can do is cry.

Hi guys, I have had the same problem and nothing else worked for me that was previously mentioned in these 4 pages...

I found a link to a Nokia Tool via another Forum and managed to use that Tool to do a Factory Reset and this Fixed the Security Code prompt on my Nokia n8!!  It seemed to have reset the Security Code to nothing! This was the only thing that fixed that annoying Security Code prompt for me. I must warn that you might lose some data / apps / info off your phone if you use the tool, but it does work. I am about to sell my Nokia N8 anyway so I already removed my personal data and had nothing to lose! I noticed the Maps (content) was gone after doing this but not sure of any other data loss. 

The Tool I used is called MyNokiaTool (google it) and you need to connect the phone to your PC and find the option in the Tool to do Reset Settings - after you "connect" the phone to the software.

Goog luck 

None of the following worked for me (just like some of you had done & failed too):

I tried Hard Resets (4 button combo reset),

Entering Codes 12345, 0000 & several other codes I might have previously used in Anna, nothing worked!

I also uninstalled the 2 applications related to F-secure

I also reinstalled Belle via Nokia Suite at least 3 times

And rebooted the phone countless times due to the 5 incorrect attempts and locking the thing.
