Network / IMEI Problem

---

hi guys, i have a gsm gnex and everything was just fine until last week when i reboot my phone and it came back with no signal i tried several reboots with no luck, so i made a factory reset and still no fix at all... and then i saw that IMEI and Baseband was shown as "unknown" in status. Like image below.



So i was reading a thread in HTC Sensation forum and someone said that removing the battery and waiting like 20 minutes solve the problem for him... i tried and yes, everything was back, my imei, baseband, etc... BUT, the problem was not fixed.

- i can't reboot or shutdown the phone, if so, it uses to turn on with unknown imei, unknown baseband, etc (sometimes it turns on okay, with everything there, i don't know why, it's just random), but if i wait, it magically appears and i get my signal back or i could do what use to be faster: let the phone off for five minutes and turn it on, and then it comes with my imei, my baseband... all okay!

- i also need to disable 3G network because it drops my signal, what makes me need to turn off the phone, or just wait the signal magically come back again......


i tried to change radio, rom, back to stock, restore nandroid backup that i made in the day one after root the phone, etc...

anyone ever seen anything like this? in any devide?

i would appreciate any help...

I can help you restore your original imei but I have to have your phone with me

Sent from my Galaxy Nexus using XDA

i don't believe i need to restore the imei, because after some reboots and sometime with my battery pulled off, the imei just come back like magic. Like the screenshot i took right now:

Oh lord, you'd better hope I don't get the bright idea to drunk dial tonight. My Portuguese is even worse than my Spanish.

I'd probably go ahead and b/u your IMEI just in case.

Which ROM did you flash? ...generally your issue occurs when a CDMA ROM is flashed onto a GSM Nexus.

No, never flashed a cdma rom, in fact i was "stock" when problem began... =o/ i had manually updated to 4.0.4 by downloading stock rom on google source...

I flashed several roms after problem begins and now i'm on aokp, Build 34...

well, after several research i figured out the problem is well known by galaxy sII users, like described in this thread: http://forum.xda-developers.com/show....php?t=1261948

my problem is exact the same, i can even do the temporary fix proposed there

but solution there doesnt seems to work on gnex... does anyone know a way to 'adjust' it? since gnex doesn't have efs folder...

thanks!

actually, the question is, can i use these codes replacing "/efs" with "/factory" and "/dev/block" with "/dev/block/platform/omap/omap_hsmmc.0"
