hi,
today I had a little set-back while trying to root and flash a rom, phone kept on rebooting in recovery.
So I flashed stock via Odin, but now my IMEI isn't correct and I can't use my phone anymore.
Any suggestions?
phone is I9300
Depends what you did, if you flashed 4.1 then just flash 4.3 to enable the efs to be read again.
If you've corrupted efs then you'll need to restore your efs backup, else pay for a repair.

well, I was on 4.3, and rooted it.
Then I tried to flash a rom but that didn't went well, so I had an old firmware, think I did wrong at that point.
I'll try to flash 4.3 via odin or try KIES to let it fix....fingers crossed
fixed the problem.
I flashed a stock 4.3 firmware via Odin and IMEI was recovered, everything works fine now.
Running on Liquid ROM now :good:

Sorry to ask but, how do i do that? Is it this? http://forum.xda-developers.com/showthread.php?t=1506330
Ive flashed the AT&T stock rom already and it doesnt fix it
I had to do this the other day, for the same reason. Returning to stock Gingerbread from the link you posted did not restore the IMEI for me. However, I found a stock ICS .tar online that DID restore my IMEI: http://www.hotfile.com/dl/162779447/3bb6230/I717UCLF6_I717ATTLF6_ATT.zip.html
I did a full nandroid backup, flashed stock ICS and verified the IMEI had returned, re-flashed TWRP and made a backup of only the EFS partition, restored my full nandroid backup and then restored the new EFS backup over that. Worked great and I had almost no downtime.
Only issue I have now is flashing the GB modem sets my IMEI as 0. I normally wouldn't care, because I can still connect to everything, but Cerberus won't run without a valid IMEI. Restoring my EFS backup does nothing. Returning to the ICS modem restores the IMEI again. Blah.
still availible?
Do you by any chance still got the file, I have been looking for such a file like that, my imei shows null as well as the baseband does and i have tried every single modem or ROM i've found , had no luck, most of the roms will just reboot every 2 min on my galaxy note, but 1 stock ICS at&t rom, works perfectly but got no luck getting back my imei, would be so great if you could help.

Hi guys,
Ok so I have managed to get my GT-I9300 (inter) network free stuck in a boot loop, after trying to put it back to stock I somehow lost my EFS folder and now get an error "E: Faild to mount EFS (invalid argument)"........yes everyone face palm as Im another one of them. However I have got a copy of my EFS folder that I made with Ktool, but its at this point im stuck.
Im really sorry to be posting another about this issue but after spending hours searching I can't find an answer, lots about people not having a back up but nothing for those that have.
What i need to know is how do I get the back up onto my phone?
I have the stock firmware and the back up EFS folder, but Im stuck as to what to do to "mount" the EFS and replace all this. I have downloaded EFS prof but the phone won't connect to it, it also won't connect to the Kies package either.
I admit I am a noob and should of stuck with the crayons rather than messing with things that i didn't really know, but its done now and i would really love to get your help (in simple talk if possible).
Rather than someone typing out the instructions again why not follow the guide in general stickies on how to return to stock?
Once the phone boots again you can root and copy the efs backup onto the phoen again.
Cheer, will look there. Hadn't found that section in my search, will give it a go and keep my fingers crossed

Gone through the stickies, and followed the steps to return to stock. But due to the EFS issue its still stuck in bootloop, I flashed the stock recovery tar and then the stock rom.
Mmmmm I need to get the efs off the pc onto the phone again without having to have the phone boot
Obvious question, did you do a factory reset in recovery? Also, did you go from an EMG rom back to an earlier version when flashing stock?
You shouldn't need to flash a recovery, a stock rom downloaded from sammobile includes everything you need.
The only way to restore the efs folder in recovery would be to flash a custom recovery, like Philz, and then use AromaFM to copy the files to the phone.
Hi, yes tried the reset but it did nothing still stuck on bootloop. Erm EMG?? I had just put "I9300_Omega_v46.1_XXUFME7_md5_1C591CA15E556884E4B6AFC89E5A682F" on and then went back to stock.
Odd, a full stock flashed using odin should solve the efs mounting problem.
Did you remove kies before using odin? Did odin give any errors?
If in any doubt use this guidance to flash your stock rom, read it carefully and follow each step exactly:
http://forum.xda-developers.com/showthread.php?t=1671969
Which stock rom are you trying to flash?
Im using this one BTU-I9300XXEMG4-20130724164355, I didnt remove Kies didn't know that could cause a problem. Thanks for the link will check that over, I'm just a bit gutted that I backed up as always and I'm still getting the issue ahhhhhhh.

You my friend are my hero (also the guy that wrote the guide)................followed the steps and the phone has booted no problem......I can not add my imei back with ktool once rooted again!!!!!
Glad to hear it worked, flashing a full stock rom often fixes the imei problem but if not then you have your backup to restore.
Easiest way to root is CF Auto Root, make sure you follow the guide exactly.

I might just take a break from messing, the misses gives me the dead eye every time I pick the ohone up now :crying:
One last question to you sir, the firmware of the guide has put me on 4.0.4, and its not letting me update off Kies. Is this because the build is old or not official. If I download the most upto date firmware off sammobile will I have to up date the kernal again too??
model number - GT-I9300
Android version - 4.0.4
baseband - I9300xxle8
Kernel version - 3.0.15-554452-user
build number - IMM76D.I9300XXALE8
cheersagain
Kernel is included
Ideally you should have used the guide to flash the EMG4 rom you'd already downloaded. Don't leave it long on that old firmware as it doesn't protect against SDS.
Oh, don't use kies as it's a waste of time.

Well its all gone a bit strange to be honest, after getting the phone to boot finally I went ahead and flashed the newer firmware I9300XXEMG6_I9300PHNEMG2_I9300CEEMG2_HOME.tar.md5 . The phone went straight back to bootloop!!!
So currently re doing what i did to get it running in the first place, problem is that leaves the phone in factory mode and the ktool says it is restoring my efs but it doesnt seem to do anything!
so after more grief off her im stuck again.
I have writen down PDA:ME7 PHONE:ME7 CSC:ME7 (eur) which i think is off the last working firmware but not sure which one it is!
Now you can get the phone to boot the problem is mostly done. You should find several threads in this forum on restoring the efs and factory mode (the two are related) also about bootloops with corrupt efs partition.
Well tried all of what i can and understand, still nothing! Stuck with the 004999010640000/01 imei, its out of factory mode and everything works bar the network connection. Managed to restock and set counter to No, all official and ready for warrenty fix....that is unless anyone has any ideas.
This thread answers all the efs questions, if you have now flashed an EMG stock then the efs partition is probably corrupt. As you have a backup this shouldn't stop you from getting it working.

Thanks again for all your help, I had followed these as best i could but no joy. I think I've 100% killed it. Like I say managed t get it back to stock and use the fantastic triangle away package....thus phone is as untouched......so swallowed the I told you so pill off her and took it to the service centre (which happens to only be 3miles from my house bonus). They did all the checks and accepted it under warrenty, down side i just have to wait up to two weeks its return!!!
Lots of lessons learnt, I origionally just wanted to delete the bloat ware and got carried away, thinking I was not a noob and some sort of phone god the roming followed.
Thanks again for all your help, I will read so much more about what to do if I do go down this line again.
Hello All.
I have a Samsung Galaxy S3 international (GT-I9300 - OS 4.0.4 - I9300DXLE8 baseband) I applied a ROM update (4.2.1) and lost signal. I then flashed again using various ROMS but nothing. I did some research about the EFS folder and using the XXEMG4 modem binary to get the IMEI number back from the generic one but now I cannot connect to any of the mobile carriers that are found. I have to admit, before I discovered the XXEMG4 issue (from a thread here) I did (mistakenly) look in to the EFS folder and I confess I most likely have messed that up and that may be the reason I cannot get a signal any further even though I can get the correct IMEI?
Is there anything I can do which would not involve sending the phone to Samsung? Flashing the stock ROM did not fix it and now, I have found, regardless of what ROM I flash, I must also flash the XXEMG4 modem as well otherwise I just get a generic IMEI number. I blame myself and my own stupidity for not reading more about the EFS system first (and not making a backup either) so I just wanted clarification that there is nothing more I can do.
To summarise:
Updated ROM and lost IMEI (generic)
Did not back up EFS folder
Flashed various ROMS - no service & generic IMEI
Flashed ROM with XXEMG4 modem
Phone IMEI is correct but still no service - emergency calls only
Ariza patch did nothing, factory reset does nothing, stock ROM does nothing.
Many thanks for your time.
Install the patched mg4 modem and all should be fixed

Start from beginning flash leaked firmware via odin from sammobile
Then root by cfroot
Install recovery and then flash custom recovery..
Also if u do have a backup of stock with working imei then u cn restore that if u dnt want to do the odin procedure..
Thanks for the replies but I seem to have fixed it.
I restored back to stock ROM, restored EFS Backup using KTools and restarted the phone and all is well.
I am now backing the phone up completely using EFS Pro.
Many thanks.
If you've corrupted files in the efs folder then no, there is nothing you can do yourself. The repair should not be too expensive as no hardware needed replacing.
Edit. You wrote 'didn't backup efs', but now say you've solved it by restoring your backup -which is the whole point of taking a backup before you flash anything.

Dear,
I installed 4.4 RC1 PA, per the instructions, however I'm stuck in bootloop. Then I tried to go back to an earlier version, of course with a suitable kernel, but still the same. Then I installed the stock rom 4.1.2, and again repeated bootloop. Finally install the stock ICS, the system is booted, but I do not have a GSM network. Once again I try to install custom, happens to bootloop. Works only stock ICS but without GSM network. Do something was wrong?
Thanks in advance!
I guess your EFS partition got all messed up while flashing.No baseband,no serial,no imei,no signal and so on.Have you made any backup of it?
This EFS thing is tricky.Search around here to get an idea about this.

What you think, is this possible way to fix? I'll try this. http://www.digitalreborn.com/fix-samsung-galaxy-unable-mount-efs/
So I assume you have a backup.There are plenty of tools for restoring it,like the EFS Professional or kTool.If your backup is in either img or tar format,easy way could be restoring it via philz kernel's advanced recovery(if you are using stock jb or ics).
hi i was wondering if you guys can help me, i have an efs backup,but i cant seem to be able to restore my imei,i tried Ktool,efs professional,nothing seems to work,i should mention that the efs backup was from a Samsung 4.1.2 stock now my phone is on CM11
thanks
I dont know if cm base and sam base modems are same but if they are:
Firs option: many custom roms come without modems to prevent the country issues so assume that your old modem is still installed you can try to install a new cm modem or like i said if they are same a new version sammy modem.
Second option: go back to stock 4.1.2 and see if your imei is still intact. If not restore your 4.1.2 imei see if it is back. If It is back first try to upgrade official 4.3 via odin then install cm 11 with wipe...

thanks for replying, I flashed a patched modem and kernal from a different post, but I got boot loop,so I restored a backup that I made before flashing from recovery,and for some reason every thing is OK now maybe restoring is the silotion.
BTW the backup was made after I restored my efs.hop that helps someone.
In a way you helped me, thank you.

You got bootloop because that modem and kernel are for sammy 4.3 and yours is CM. The backup you restored, is it nandroid backup and is it 4.1.2 ?

no, the backup i restored was from CM 11,thats what surprised me i made the backup in philz touch right before i flashed the patched modem and the kernel to try and solve the imei issue, it was a normal backup (the one where you back every thing),meaning the imei problem was still there,but it was after i tried to restore my original EFS.
so here is what i did in steps
-got corrupted imei on CM 11
-tried to restore with my EFS backup that i made while i was on sammy 4.1.2 using different apps and methods didn't work
-made a full backup using philz before flashing a new modem as suggested
-got boot loop after flashing a new modem
-restored the backup i made before flashing the modem and for some reason my imei was back

I think the reason you got your imei back is the modem you installed with the kernel. So here is what i think happened. You had bootloop so restore got your old kernel back and modem stayed intact. Shortly if you had just installed a new modem from the begenning you would have sold your problem i always say best way to learn is try and fail. i am happy that you have your phone back [emoji106]
I also suggest you to replace the modem with an unpatched clean one. You can have network problem in the future...
