Unhappy Could not Activate my device...

Please Login to Remove!


I'm newbie in using and administrating BB. We are using BES, my BB model is 7290.

Before, I have once removed the SIM card, and then I found that I'm not dowloading any new mail. So I used Enterprise Activation to activate my device again, but it's not working.

I wiped my device, removed my user account on BES many times, but I still cannot activate my device, the error is:

Decryption failure. Please regenerate key.

I have tried to generate key from desktop manager, it's successful, then I tried to regenerate key from my device again (Options -> Security -> Services), but I got the same error message...

Could anyone help? Many thx!!!

Default This might be helpful

I would suggest that you once again do a wipe of your device, remove and re-add your BES account. Before proceeding to devce activation, check your DM to ensure that it's set to automatically regenerate the encryption key. The thing about key regeneration is, if you do it too often, there's the possibility that the "keys" on the device and the server become out of sync. You should only have to generate the keys once, unless here's an issue that requires a manual regeneration.
If after wiping the device it comes up fine (you can see the network provider's name, GPRS is in caps)....then proceed to activation. You have two choices here, wired activation using the DM or wireless using EA.

Here's another link..

Unhappy Can activate through DM, but not Wireless

Thx, dev.

Actually I have tried what you said, and followed what your link said, I could activate through DM, but not wireless.

I find that it seems BES remembers the credentials of my account, no matter how many times I delete my account, after I re-create it, the PIN number appears automatically.

And when I try to do enterprise activation, I always receive an email from [email address], saying:

This message is used to carry data between the BlackBerry Handheld and an associated server. Please do not delete, move or respond to this message - it will be processed by the server.

If I map the device to another account, this message will not appear, and I can do wireless activation successfully.

I suspect it's the problem that the BES account remembers the credential of my account, how can I clear those data thoroughly?

Thx again!

what mail platform (Exchange, Notes, Groupwise)? with Exchange, that information is kept in hidden folders in your mailbox. the way to remove it, with BES 4.0, is to remove the user and click Yes when prompted to remove all information. prior to BES 4.0 (3.6, etc), you'd have to use dbclean.exe. adding the user back should result in a 0 PIN.
In the beginning the Universe was created. This has made a lot of people very angry and is widely regarded as a bad move.

Sorry, I haven't got back to you guys soon...

Thanks, jibi, you're right.

I got the dbclean.exe from our local vendor, and run it on my PC, and that fixed the problem!

Actually I have tried to removed my Exchange account and mailbox, but the problem still there, and we are using 4.0.

According to our vendor, the reason is just what jibi told.

Anyway, thanks everyone!
