Unknown Imei and basebandm, and find a way to get back to stock.

[tinclan]

So here's a little bit of context first:
1-This is a friend's phone
2-The data partion corrupted on its own
3-I unlocked the bootloader
4-Flashed twrp
5-Formatted data partition through adb
6-Flashed cm11 normally

Now the phone network doesnt want to work and both the imei and baseband show up as unknown even though they show up normally with the command "fastboot getvar all" .
I've tried restoring to this backup http://forum.xda-developers.com/showthread.php?t=2775650 but it kept crashing and rebooting and it had the same imei and baseband problem so i went back to cm11.

Any ideas?

If imei and baseband are missing in Settings it is a sign that it is a hardware issue and will cause a host of problems. If under warranty you can return to carrier or HTC for repair. However, since you unlocked the bootloader and I would guess it is S-ON you will not be able to return it to 100% stock for a warranty repair. You can still return it but will have to pay for the repair.

Omg man that's totally not the response I wanted to hear. What about the fact that the iemi and baseband show up fine using the "fastboot getvar all" command? And BTW I only unlocked the bootloader when the data partition corrupted, before I tried to unlock the bootloader HTC had already told my friend that they're gonna charge him $200 bucks to fix that issue and that wasn't really an option for him. Also, do you think the issue maybe because of corrupted firmware. I though that maybe if we werent able to fix the issue then I works just get s-off and run an ruu then try to remove the tampered banner and get back the bootloader states to "locked", what do you think?

It is worth a try to see if the firmware or RUU will fix the issue, however, if it is hardware then it will not.

Thanks for replying! I will definitely try flashing the firmware and RUU before concluding that it's a hardware problem, but btw do you know if i need s-off to flash firmware for the same os version and same cid/mid or will it just check that it's compatible and overwrite the one already there?

If you are S-ON then RUU & firmware must be the same version or higher and signed. When you flash the firmware or RUU it will overwrite the partitions and it may wipe all of your data as well. So, if you can you will want to copy all of your data/files off of the phone prior to flashing the firmware or RUU.

I really appreciate your help, I have one final question. If i extract the firmware from the official ota update then it's signed, right? Also, do i have to lock the bootloader, flash the stock recovery and have the stock sense ROM or if having the relocked bootloader and/or stock recovery enough?

• Yes, the firmware in the OTA is signed.
• Yes, you must lock your bootloader prior to flashing firmware or RUU if S-ON
• If you flash the stock firmware it will include the stock recovery

Thanks a lot for your help
