[Q] cm10.1 on xperia z no imei number found

Hi i have the z and installed cm10.1 fxp211. It installs fine but when i go to the rom, i have no reception. I go to the about screen and it shows no imei number at all. can anyone help me on why this happens? i have tried taking the sim out going into aeroplane mode and rebooting the phone putting sim in and it still dont work. any help is appreciated.
Try reflashing previous version ( fxp 210 ) and check again. Maybe something went wrong with the modem driver or flashing procedure.

Same thing happened to me. I've also tried the said steps but still no IMEI is shown. I even reflashed it to stock rom, restored my TA Partition but to no avail!

I have the same trouble like you guys.
I installed CM 10.2 Milestone1 and after some time my IMEI went lost.
So far I found no solution.
Did you find any solution in the meantime?
What did you do with your phone now?
I had it replaced. My phone was under warranty.

Okay. In the meantime I was able to recover mine. In Clockworkmod I formatted all partitions (real format, not just wipe option) and installed CM 10.2 nightly, then I had my IMEI back. Now I did a backup from within Clockworkmod, next time my phone gets bricked I have a backup now.... Should have done that earlier...

[Q] Spontaneous reboot casued unknown imei and baseband

Hi all
I'm running PAC-ROM. So far everything has been fine for months, but sometimes when my device rebooted spontaneously it would be missing its signal. A quick reflash of the ROM usually solved this, but its not working this time.
Today I've found out it's because there's an unknown imei and baseband. I've searched and found a few threads but so far have nothing to work with.
I've got s-off if that helps. M7ul.mcan anyone help me?
Thanks in advance

Baseband Unknown & IMEI null (SM-G900A) - Please Help

The story
Hi everyone, thanks for reading me and thanks for your time.
I am stuck with this galaxy S5.
I got a S5 in the past, a beautiful SM-G900F on which I run lineageOS no problem whatsoever.
I bought another S5 from ebay, turns on it's a G900A.
Had problems from the start, the phone seemed to often restart instead of turning off normally, and I had severe battery drain both while on and while turned off. So I went to this section and looked at Root, Roms and other cool stuff and followed the guide to put up a custom ROM.
The problem
The first step, installing the experimental firmware, seemed to work but after reboot no OS would install, instead I got "MODEM CRASH".
So from there, I tried to roll back to stock.
I put on BOF3, which works, but since then I have baseband null and IMEI unknown.
Panicking, I tried to install COI5, but same problem there and also multiple bugs, so I went back to BOF3 and it's all functional, but same baseband/IMEI problem.
I have tried to reset to the oldest stock G900AUCU1ANCE but ODIN fails at the very start. I seem to understand I'm on android 5 and cannot rollback now, somehow.
If anyone has any idea on what I can do realistically.
I have no EFS backup as when I started I didn't know what EFS was.
Thank you all for your help.
I have seen many topics with this problem but I have only been confused more by them so forgive me for posting here.
Bump!
Can anyone help?
