restoring to the default firmware is the same as flashing a new firmware.
download the firmware and flash.

but serial number missing etc seems like an issue with your efs partition.
You might have to try to restore it if you have a backup of the efs.

well at least all is not lost if you can see the imei number.

See if a factory reset solves the issue or not. if you are rooted there are some apps available to backup and restore your efs.

thank you very much they are unavailable cuz they are switched off now all is fine again :D

Wow, thanks god i found this thread, i have the same problem, updated to 4.0.3 and lost my serial number but not my imei.

So resuming, you just had to downgrade to the original firmware right? or you had to do the efs thing?

:shakehands:
