I I accidently flashed ICS firmware over JB via odin,now my phone shows generic imei,hence no network,plz help me to sort out the issue...
Flash a full 4.1.2 stock rom, at least EMG4 if you've ever used an EMG rom previously otherwise your efs folder won't be read.
If imei still corrupt then restore your efs backup.
Don't stay on ics, it will cause sds.

Hey Guys,
So I had my usual SIM card working as usual on G4 stock 4.1.2 firmware. I later on flashed CM10.2 20130814 Nightly build after which my phone was stuck on Emergency Calls only. I flashed three different stock 4.1.2 official firmwares after that but nothing seemed to fix it. They recognised my SIM and carrier though they weren't able to make calls and whenever I tried to it gave me the error message "Not registered on Network".
It is a fully unlocked i9300. I would really like your guys help on this.
Questions go in the Q&A forum, report your post and ask for it to be moved.
Does your IMEI number in phone match the one under the battery?
Did you make a backup of your efs folder like all the guides recommend?
If your IMEI has changed and you don't have a backup then flashing the latest full stock via odin on your pc sometimes enables the partition to be read again.

Well, This is the Q&A section. Anyways, I didn't make a backup of EFS. I tried flashing stock as mentioned in the OP but it didn't prevail so what should be the next line of action? xD
Hah! Sorry, my browser took me back to q&a from general.
Does the IMEI match?
If not then you need a repair.
I am currently back to flashing another stock firmware so didn't check. If it doesn't match then what sort of repair would it need?

Problem: /efs partition format changed
The latest 4.1.2 UK (XXEMG4) and India (XXEMG5) ROM releases (Which come with MG4 and MG2 basebands respectively), actually change the format of efs.
If you have flashed a, XXEMG4/5 ROM at any point, you are now in a situation whereby only an MG4/2 baseband can read the IMEI in /efs. The new efs format is not backwards compatible with older basebands. Probably, all new basebands will be compatible so in time this issue should diminish I expect.
If you have ever flashed XXEMG4/5 ROM, to keep your IMEI working, you must:
Stay with the basebands MG4/2. You may flash other ROMs but must return to the MG4/2 baseband.
Restore your efs backup (taken before XXEMG4/5 ROM install) to use older basebands.
Please note, it is flashing the ROM that alters efs format, not the basebands themselves. You can flash the MG4 or 2 baseband safely on their own and return to an older baseband without issue.
You can download an MG2/4 baseband package HERE
Aroma installer, choose between MG2 and MG4 basebands
Basebands alone do not alter efs format
Backs up EFS in an uncompressed format (Use Root Explorer to restore)
Does NOT include RIL, works on AOSP and Sammy

NO it didn't work as i installed the latest firmware through odin, and then get OTA as well but it didnt solve the issue, then i installed the MK6 BTU firmware but it didnt work as well.
tired of installing the ROM's and Patches but non of them worked, is there any posibility to get it in working condition or should i use it as IPOD???
Take it to a repair centre and pay them to recode it, make sure it works on 4.3 firmware before you pay them.
Patches are a work around for modified efs problems, a corrupt or wiped efs can only be solved by professional repair.
Hey guys,
Well, I've had an IMEI issue recently after flashing stock rom back to my S3. When I have flashed the stock rom back, it's written, "Emergency Calls Only" and my IMEI became 0049 and so on. After a while of solution searching, I've seen some post about baseband and modem V1 V2 or something which I don't understand much about it. So, what I did was to flash back to my old rom I've used before and now it worked! and that rom was NeatRom based on XXEMH1.
Now, what I want to ask is, how can I go back to stock rom with my network working properly without emergency calls only and messed up IMEI?
Update: Read some guy posting things about this rom that I'm using. He said it has an outdated baseband or something and I guess I may have to flash kernel, modem to make it catch up with the ROM itself. about it, if anybody has the file, would you please provide me with links to download? Thanks.
Thanks in advance!
Go and read the basics in general, stickies before you flash anything else.
You can't flash any Rom with a modem earlier than EMG4 now, so your stock rom was probably before this.

Sorry if I did anything wrong and thank you.
I have searched and think I know what I'm doing, but I wonder if some kind soul could confirm what I think, before I eff my phone up?
I'm currently running a 4.2.2 Samsung ROM (Archidroid) but I'm not happy with the lag. I want to go back to a 4.1.2 ROM.
Am I correct in thinking that I can just flash the new ROM and then restore my EFS backup, and I won't have a problem with losing my IMEI/phone going into factory mode, etc? My EFS backup was done when I was on a 4.1 ROM. Or do I need to restore EFS before flashing the new ROM?
Thanking you!

just back up efs every time. be sure> flashing firmwares based on MG, changes efs format to a new one. after that if you wanna flash a firmware based on previous releases(to XXEMG4), you will be facing network problems like no data connection, no calls, no text messages etc., so once you flash a firmware i.e released after MG4, be sure the next custom rom/ stock f/w you flash is newer to it. good luck
Can I not flash an older firmware safely by restoring my EFS? Or is it risky?

Yeah thanks, I've read that more than once:
If you have ever flashed XXEMG* (or newer) ROM, to keep your IMEI working, you must:
1. Stay with the EFS v2 basebands (MG* or newer). You may flash other ROMs but must return to the MG* (or newer) baseband
2. Restore your EFS backup (taken before XXEMG* or newer ROM install) to use older (EFS v1) basebands. EFS backup must be an EFSv1 backup to use an EFS v1 baseband
3. If the above don't work, consider sending for repair...
This is the part I am worried about.

that's what exactly i was trying to tell you. XXEMG4 f/w is some what problematic but the f/w-s released after that are good enough. once you flash any of these f/w-s, back up your efs for sure.
:good:
Yes, but I want to go back to a ROM with an earlier baseband than EMG4, so I can use a custom kernel. The performance on later ROMs with the standard kernel (which is all you can use at the moment) is not satisfactory.
So my question is, in order to go back to a ROM based on firmware earlier than EMG4, can it be done SAFELY? If so, do I need to restore my EFS backup before I flash the ROM or afterwards? Or, if it's not safe then what should I do to minimise my chances of messing my phone up?

Try different 4.1.2 stock roms prior to 'MG' series. Make a clean installation.
As you were on 4.2.2, you were probably not on efs v2. Take backup of efs.
Sent Via I9300, Stock XXUFME7, 4.2.2.
how to restore to 4.1.2??
I have installed 4.4.2 AOKP firmware on S3 GT I9300. I have backup of previous version 4.1.2 through CWM backup. Now i am trying to restore 4.1.2 backup through CWM but unable to do. I have tried a lot but can't restore previous.
Plz anybody help me resolving this issue. how to restore my previous version 4.1.2 from 4.2.2 with the existing backup?
Thankss if anybody help me out.
Hi guys , so i was having some problems with calls on my gs3 , (i was sending sms and atuff normally, but from yesterday till today i could make calls in the morning, i tried my moms phone and the carrier signas and status seems ok. so i tough it was a modem problem, i flashed "I9300UBEMH2_I9300UBEMH1_I9300UWHEMH1_HOME.tar.md5" from panama and the signal was OK . so i tried to reflash another modem and i got the "no sim card" error. tried a bunch of modems and none of them worked.
So now im flashing the stock one, but as far as i know it wont read my imei because of the panama was MG4 or MH1 it changed the efs format. But i will flash a mg4 modem with the stuck UBELL1 from movistar southamerica and see if it works .
My problem here is , can i flash an mg4 rom make a back up of the efs with ktools and restore the efs backup on a previous not mg4 rom? and it will read my emai ? (this is happening because i didn't made a back up of my original efs)
Also i was wondering, what will happen when i want to install a 4.2.2 again in the future? or a 4.3? i won't be able to do it since i need to use a mg4 modem to have signal? or can i back up a working efs with a mg4 rom and restore the efs back up on a stock not mg4?
#BTW my sg3 is still attached to movistar (is not unlocked)

This is already answered in the thread you said you read.
today i had some idea. But not im not sure about it . So here it is. I am wondering if its completely necesary to use mg4 modems forever on my device to get my imei readen. So is there any kind of method to take the v2 imei readen only for mg4 modems . and make it readable for another basebands modems? like ubell1 ? . i tried installing a 4.2.2 rom, then flashing the mg4 modem. once the imei got readen i made a efs backup with HCk tool , then i change rom and restore the mg4 efs backup . But i got nothing . the imei is not being read.
do you know if what im trying to do is possible? or maybe (as i said before) i will have to forever use mg4 modems on my device? .
with mg4 modems im not having problems is just that , it's a pain in the ass being changing of basebands everytime i want to flash a new rom.
You can only use mg2, mg4 or mh1. Basically any modem released since July. Stop living in the past

i have just 2 or 3 simple questions. especific quesitons that i cannot find the answer on your post. or maybe the answer is on the next 11 pages? you mention on your post only MG4 roms or newer. don't say anything about Mh2 . so the questions is kinda easy, would i am able to have signal and imea read on a 4.1.2 if i flash a mg4 modem after install ? . and same thing happen to 4.2.2 or 4.3 will i have to always flash a custom modem to have my imea readden?

SO i will have to back up and restore the mg4 mh2 efs every time i want to change rom for a older one.. do you know if 4.3 (as it will be obviosly new) will have a mg4 or mh2 mh1 modem? . im kinda having problems on my calls . internet and messanging are just fine . but some times when i want to call the automatic operator says " the call could not be proccesed" but dunno if this is a signal problem or it is just me.
