[SOLVED] Lost IMEI, backup does not help
I'm kind of frustrated now, because I cannot get my IMEI back, though I have EFS backups, and do not get any errors.
I was using CM7 before. Everything was fine, except the KJ6 modem, which worked bad where I live, and that drained the battery. So I decided to go back to a BML ROM until it's possible to flash modems in CM7.
I used a 1-Click to get back to stock with CWM. It went fine. Then tried to flash Erik's MIUI. And for some reason it started bootlooping (this did not happen before).
I finally un-bricked the phone using Odin. But I found out I lost my IMEI. Have no idea how this happened. The EFS folder was there, all files too, but no IMEI, no baseband, no calls.
I had a backup of /dev/block/stl3. So I deleted the /efs contents and flashed the backup with Heimdall: "heimdall flash --efs efs.img" I got no errors, and the EFS folder was populated with files. But it did not help - still no IMEI.
I decided to go back to CM7 then. I installed CM7 before, and it worked fine. So I did everything as before, restored EFS, flashed the update. And got no IMEI in CM7 too.
I did it again, restored EFS, flashed update, even fixed permissions, but nothing helped. I got no errors when flashing, and still no IMEI afterwards.
I'm kind of tired of trying now. Would appreciate any help. Thank you.
