Hay guys ,
I'm Mina Alphons and I having a problem with my SGS3 I9300 16GB
...
my phone doesn't read my imei when i install a MG4 or higher modem !! it can't be upgraded to efsv2 !!
i can't upgrade my phone to android 4.3 JB cause my IMEI will be like that 006.....
I tried to flash my old modem that i use now MB5 on 4.3 .. and i get unknown imei and serial ...
what should i do to upgrade my phone to 4.3 without imei problem or modem problem ???
in a easy way
I'm running 4.1.2 stock rom .. every thing works fine
upgrade to 4.3 ... imei problem
my efs partition can't be updated to efsv2 what should i do ?????
any one help meeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
Well thats odd. First make a backup of your imei if its not corrupted in the 4.1.2. Older than MG4 modems have efs v1 but MG4 can read both v2 and v1. Upgrading has never given a imei problem in my experience, only downgrading. Again BACKUP your IMEI. Factory reset and flash a stock rom do try 4.3 after making nandroid and efs backups. Which rom are you using btw?

Guys I have been having a hectic time with this no network issue in my i9300. I upgraded from 4.1.2 to 4.3 without backing up the EFS folder and tried to come back to 4.1.2 and then the network registered problem came. So after many failed attempts I flashed the stock 4.2.2 via odin and gave my phone to a shop and got the corrupted EFS folder done with the repair box. Now the thing is when I flash Neatrom or the Omega 4.1.2 roms I do not get the network. I get my network ONLY on my stock 4.2.2 rom which has the patched MG4 modem. Please help me to downgrade and install Neatrom 4.1.2 rom and get my network back.
I have got a backup of my 4.2.2 EFS folder.

hello, I know there are plenty of threads regarding this. I went through all of them. I just want to know if anyone else encountered a problem exactly like mine.
Hello!
I'm with CM11 unoffical 4.4.
My modem is XXEMG4 and I would like to go back to I9300XXELL4 now I know that there is a problem with that and that there is some kind of fix but I could not find an answer for it...
all I could find is solution if the IMEI is 0000 or no S/N but that is not the case for me...
Please I would appreciate your help.
TNX!

My phone was working properly when it was on stock 4.0.4.
I did Cyanogenmod 10.2. It worked but no signal.
I researched on this and found something about updating modem/radio.
Went here: http://forum.xda-developers.com/showthread.php?p=28033515#post28033515
I downloaded and flashed this one "DXELK1" since it said SE Asia and I live in the Philippines.
Still no signal + unknown baseband, number, IMEI.
I tried flashing 4.3 modems found here: http://perka.zapto.org/ but problem persists.
I am now downloading stock firmware 4.1.2.
Please help me. Thanks!

There isn't one answer, it depends on what has been done to your phone.
