Hey
Before you ask I have read the info on http://forum.xda-developers.com/showthread.php?t=2393289 regarding this issue but either it doesn't work or I am not executing it properly (probably the latter) and I'm not sure what is going wrong.
Here's my situation. I flashed Android Revolution HD 32.0 with XXUFME7 firmware (which I believe is later than MG4) and have the "no service" problem due to corrupt efs folder. After panicking because I didn't backup my efs folder I flashed back to unrooted stock via Odin and hooray, everything was working again (signal and registering on network). So then I rooted (and it was still working) and used EFS Pro to make a back up of efs folder. I then reflashed Android Revolution HD 32.0 and restored the efs folder but it still didn't work
Could someone give me any advice on how to rectify this problem? I think I might be doing the wrong thing with the efs folder. I'd quite like a TouchWiz ROM so would like to get this one working.
Thanks in advance for any replies
ME7 is older than MG4
Suggest you stop at the point it was working and read the basics .
Basics read first.

I did say that I've already looked at that link but didn't know what was going wrong. However thanks to JJEgan I have sorted this out. I was assuming that ME7 was newer than MG4 because Android revolution 32 is after 29 but ME7 is older! The stock rom I flashed (without making a backp of efs) was MG4 and so this is why it wasn't working when flashing the ME7 rom. I switched to adnroid revolutoin 29 which is MG4 and it works fine now.

Because I am a fool! And in the panicking mode I was in I didn't think why G = July and realise that E = May and simply went by the release dates of the roms. Apologies to all for this silliness!
No worries. One piece of advice (which can be hard to follow).... never panic. It's hard but important

when I flash this 'official' ROM, 4.2.2 leaked official XXUFME7
it changes the IMEI to 0049990xxx...,
and so I get only emergency calls allowed for the phone...
the rest looks ok, but I reverted to last 4.1.2 -
I am on O2 monthly contract - is that a problem?
otherwise, even though it lost phone capability, everything else seemed cool...
any idea around this without having to fiddle trying to restore the IMEI back to original...
when I flash back the last official released 4.1.2, the IMEI corrects itself...
a guru at O2 finds it weird... LOL! and said O2 does not support flashing with Odin, only through Kies...
Please Read one of the hundred other threads saying that you need to use mg4 modem since the latest released mg4 4.1.2 rewrites the efs partition.

If I understand well to successfully get the modem working with the 4.2.2 official Samsung leak, from
KIES_HOME_I9300XXEMG4_I9300OXAEMG4_1314436_REV00_u ser_low_ship.tar.md5
to
I9300XXUFME7_I9300OXAFME7_I9300XXUFME7_HOME.tar.md 5
one needs the additional step of flashing the modem file
xxemg4.zip
please kindly confirm...

I sorted it...
this is how:
1. rename I9300XXUFME7_I9300OXAFME7_I9300XXUFME7_HOME.tar.md5 without .md5 extension i.e.
I9300XXUFME7_I9300OXAFME7_I9300XXUFME7_HOME.tar
2. in Linux delete modem.bin from the resulting .tar archive
3. flash, with Odin 3.04, I9300XXUFME7_I9300OXAFME7_I9300XXUFME7_HOME.tar (that had modem.bin removed)
This will keep the correct modem.bin of KIES_HOME_I9300XXEMG4_I9300OXAEMG4_1314436_REV00_u ser_low_ship.tar.md5
and so solves the problem...
and all this can be done without rooting...

1. Flashed 4,2,2 without backuping EFS and got that imei or efc corrupted.
2. Flased back to original stock 4.1.2 and its still the same,,

hey i'm reading guides in http://forum.xda-developers.com/showthread.php?t=2344125 to understand s3 more
but i have a question about mine ( sorry for being rushing in but i do need to change my phone these days )
my s3 is on leaked 4.2.2 israel , i need to flash back into 4.1.2 stock EGYPT ( or any good custome ROM ).
when i flashed 4.1.2 EGY before it made " restarting bootloader ". so rootSU told me to make factory wipe.but it didnt work
while am reading i found that restarting bootloader is a good sign that my phone isn't brick ( note : its working normally but the leaked ROM 4.2.2 having alot of issues ).
what should i do , please ask me for what u exactly need to know of info about my phone so i can provide and fix this.
(( do i need to just wait for 4.3 official release )) ?
thanks in advance

efs is not related to rooting or custom roms mate. it is related to the network connection and your imei number. you need to back it up and keep safe so that if you face network problem after updating the phone to the latest 4.1.2, that might help you restore. refer to the thread under my signature for any queries relating to efs/imei.

Good afternoon all,
I apologize if this is a duplicate thread but i've spent the better part of the past week trying to find information on this. I have CM10.2 installed on my GTi9300. Initially i had Touchwiz with 4.1.2, I created a backup in CWM and then flashed CM10.1 and then upgraded now to CM 10.2... I really would like to go back to my original TOuchwiz and as i previously stated, I have a backup of the state before installing my initial CM...
How do I go about doing this?
Regards
I answered this in last couple of days. Let me use search

I understand but what I'm wondering as well is if possible and how I can just restore form my CWM backup. This pretty emuvh says I have to wipe and flash the firmware I want to have on my phone.
you can just go into recovery and resore. if your nandroid backup is not there than it may have gotten corrupted. which cwm are you using. ? is it up to date?
Don't forget to take into account what I said about sdcard. I don't say this stuff for fun

All my backups are there. I have CWM 6.xxx. So with my backup I can just wipe and recover?
What do I need to wipe etc? And I read about EFI backups... I don't have one of that.

I have CWM 6 and all my backups show up. What do I need to do? Just wipe and restore? What wipes do I use?
Nick
i have not used cwm in a long time . also never on this device but it is usually safe to wipe cache and dalvik cache. probably fine to wipe data if your backup is on extsdcard. i would not wipe system though . in case your backup is corrupted wiping system will leave you with no rom. if you have the option to restore backup from cwm recovery than try that . if your phone doesnt boot usually factory reset will get it to boot. good luck

Thanks man... Worked like a charm!
Model GT-i9300
Current Android version 4.1.2 (Stock samsung)
Baseband: I9300XXEMB6
Kernel: 3.0.31-1160235
Build: JZO54K.I9300XXEMD3
CWM recovery 6.0.3.6 installed, and root access.
Im planning an install of cm-10.1.3-i9300.zip and gapps-jb-20130812-signed.zip (CyanogenMod 10.1 stable) and it's my first installation of a custom ROM. Im also new to this forum, and customs ROMS in general, the last couple of days I have been reading alot of forum posts, stickies, trying to learn this.
Now I don't wanna do anything wrong and brick my phone or make EFS folder unreadable. So I have some questions ..
First, I have read http://forum.xda-developers.com/showthread.php?t=2393289 and http://forum.xda-developers.com/showthread.php?t=2035141.
But.. Im having trouble understanding, if I should do someting about EFS or not.
Will this ROM make my EFS folder unreadable? If so, what can I do about it? If I must, do I flash v2 before or after I have installed CM?
I have already backed up EFS with EFSprobackup.
As I can see I have EMB6 = 2013 Feb Rev6 which is "v1"?

Done and done.
So what you are saying that i should just flash, and if it doesnt work with GSM / SMS / MMS afterward, I just restore EFS and it should be OK?

Dont touch unless you get EFS /IMEI problems if you do see EFS/IMEI faq.
HI, good day to all,
refer to the topic as above,
i have encountered EFS been wiped, IMEI changed to 0000, no network detected after upgrade from 4.1.2 to 4.3 (I9300XXDXUGMK3).
i have tried anything that could helped such as flash MG4 modem, MK1 modem, MK6 modem but still the same. i cant try ARIZA PATCH because OS version is I9300XXDXUGMK3 not MG rom.
I need helps from someone that could bring back their network & IMEI return back. thx in advanced!:good:

hi tallman,
thx for your reply. i have checked that as well before come and posting here ask for helps. unfortunately, i have not backup the EFS folder as i thought the 4.3 update was safe without backup the EFS. any good idea to bring back the network & IMEI by flashing any modem? thx for understanding n helping!!!
If you've tried the sticky thread then you'll need a repair centre, go for a reputable one with right tools to enable 4.3 to work properly. Cheaper repairs downgrade the phone then use patches.
Your thread will probably be locked as it duplicates hundreds of other identical ones.
Post your question in the thread link I gave you it well be answered better.
