I have been running Task's AOKP (4.3.1 with LK3 bootloader) for a while now with no issues. Last night I decided to do a fresh install of it and started to run into problems now. I can no longer connect to LTE and only have edge service. After some researching I notice that my IMEI now says 0 and that can lead to not connecting to networks. Everything I have read says one way to get your IMEI back is to flash back to stock but since I have been running 4.3 there is no way to go back without bricking from what I have read? Is there any way to recover your IMEI or am I out of luck? I have tried reflashing/clearing caches and that made no difference..

I would be grateful for any help of If someone can point me in the right direction..

Thanks in Advance!

You can go back to stock. The issue has to do with bootloaders. If you try to go back to a previous bootloader once loading MJB you will brick your phone. You can, however, go back to a previous or stock Rom.

I had a similar problem after recovering from a hard brick. Try to Reflash your modem. That's what got me service again after my bricking incident. My imei number showed as 0 and my baseband showed as unknown(go to settings, about device, look for baseband what does it show, then cruise back up to status and you got the imei there zero of course).

Don't know if it will help but mine did the same after flashing a ROM. Nandroiding back fixed mine.

Another thread about to be locked or deleted. IMEI discussions are not permitted on this site due to abuse.

You can find the information you need from other sites via Google. Reflashing your modem, letting the phone catch a signal and a little time /patience does resolve the problem for many. Once you get back to normal, make sure that you back up your entire EFS /NV in case you run into any future problems.

As others pointed out, do not try to downgrade a 4.3 bootloader. 4.3 was a major update and blew a qfuse in our phones. Meaning that trying to revert it will likely brick your phone. If your IMEI is actually corrupt don't panic. You just need to spend an hour or two of quality time with Google. The information you need isn't that hard to find, it's just buried in an avalanche of help me posts.
