I have a efs backup from March to form. gz unfortunately I changed the efs partition by installing the baseband mg4. I try to restore the backup but unfortunately nothing happens constantly not working network and the imei is wrong. Any idea????
[Galaxy S III General] xerol:
guys i stucked in factorymode. any solution on it?

i tried op solution but didnt work.. pls help me guys
[Galaxy S III General] danarama:
Both of you need to delete your efs and restore the backups.
[Galaxy S III General] matrixios:
I did nothing other ... I mean the content of the file and not the folder itself?
[Galaxy S III General] stevendeb25:
I couldnt get network working. Imei 0044 serial 00000

Decide to just flash full stock mg4 and restore efs backup. Still no luck. No network.

I changed modem to mc2. Still nothing.

Changed back to mg4. Still nothing.

Restored efs. Still nothing.

I then noticed that when I was restoring efs via ktool. The backup seemed to be going into /efs/efs/ making a new efs dirctory inside the original efs folder. Dunno if this is a bug with that tool.

EDIT: just checked efs folder and there is another efs folder inside. So my mistake I was wrong.

So deleted the efs folder that shouldnt have been there. And manual copied my unpacked efs backup file by file ro efs and rebooted. Perfect everything back to normal.

Thanks for help root ;)

Hey. Long time ago now pnht lol. No not analyzed. Not modded or built any roms for 2years now. Did alot of work with atrix after symbian. But since having my son 2years back. Am a fulltime dad/ part time worker. (Sorry for off topic) nice to see someone from baxk in the day :)

How you restoring the backup? What method?
[Galaxy S III General] matrixios:
test and the ktools and philz recovery but nothing. :(
[Galaxy S III General] stevendeb25:
You got root explorer? Or some kind of root file manager?
[Galaxy S III General] matrixios:
yes I have but uses more the solid
[Galaxy S III General] stevendeb25:
Try unpacking your backup and manually copy and paste all files to /efs/ and reboot.

Also how did you change to mg4? Via odin srock mg4? If not its worth trying that as well as restoring efs too
[Galaxy S III General] matrixios:
Try but nothing:( thanks for help
[Galaxy S III General] danarama:
Did you delete /efs content first?

Tried the adb method in post 1?

Hey people,

I flashed cm9.1 and lost my efs/imei .. Ive tried everything, but if i flash any other roms (including the standard samsung one) then the phone wont go past the first loading screen ... So i have to stick with cm9.1.

I have made another imei/efs using a generator tool, but cant get it onto the phone as it wont connect up through efs pro .. I believe this is a problem with the phone not being able to enable the usb/diag mode ... Anybody got a fix for this??

Im desperate, ive been without a phone for 2 weeks now and its driving me nuts!!
[Galaxy S III General] maxniper:
I had todo that because i lost my efs backup, now i'm waiting for it.
[Galaxy S III General] jimmy080705:
Can op please update section on : "I'm stuck in factorymode, is this related?"

Many people have actually had corupted files in /efs/FactoryApp/ It appears we have the yellow writing plus our power button just instantly turns off phone (no reboot menu etc). Lock screen wont show and factory reset doesnt actually seem to do anything beisdes delete data (eg language settings stay same).

The terminal commands do not help at all, nor any abd commands, fixing permissions, flashing stock ROMs etc.

FIX:

The only solution is to make sure you are rooted, deleted the /FactoryApps folder that resides in /efs (dont delete efs!!), reboot into recovery, factory reset. The deleted folder is regenerated by itself with new files that default to "OFF" setting. Just change to "ON" using esfile explorer or equiv (assuming you have root) reboot and yellow writing gone for good.
[Galaxy S III General] danarama:
OK will do. Thanks.
[Galaxy S III General] avicohh:
Hi

I have small question.

is it possible to backup EFS v1, upgrade to MG4 modem and then restore the efs from v1?

i have this device with 'no registered in network' after each update and i'm using ariza patch to fix the efs after firmware update.

The thing is that this patch not working on the new modems because the new version, so i though maybe i can backup the efs v1 and then restore it after update to to efs v2.

Thanks guys,
[Galaxy S III General] danarama:
Yes its possible. This is all covered in post 1.

[Galaxy S III General] rauppal:
After trying all, I was unable to revive imei and phone was constantly in factory mode

so cleared flash counter with triangle away, flashed factory rom but still in factory mode and cleared data and cache.

Can someone please share their experience that sending in repair in this condition would be under warranty or samsung charged them something?

And also usually how long it took for samsung to return handset after repair.

Thanks

Cheers

Wrong IMEI

Hello everybody,

Since i tried flashing MIUI ROM on my Galaxy SIII i lost 'connection to my network' and my IMEI. I tried fixing it but it doesn't work:crying:

I tried:

flashing another ROM

flash stock ROM

unrooted

again rooted

emergency zip

I also keep having these signs on screen (See attachement)

Can anybody tell me how i get back my IMEI and network connection? How can i get rid of the signs on screen?:confused:

(Sorry for bad english)
[Galaxy S III General] spykedsystem:
Read the OP about being stuck in factory mode,root your phone,download terminal emulator and try pasting the second code (long one) in it and enter it,see if that gets rid of the yellow writing. I see you have an EMG baseband already so maybe we are in the same pot and EMG doesn't work for us only older ones,meaning we don't get newer EFS format...Try flashing XXEMB5 UK from february, you can find it on sammobile, tell me if it worked. Good luck!

EDIT: do you also have a backup of your EFS folder by any chance? and to make it easier, try flashing this http://pc.cd/eF7 it is XXEMB5 from my pcloud
[Galaxy S III General] Wess_90:
Hi Spykedsystem,

Thank you for helping me. The first step worked for me! Downloading the XXEMB5 UK file right now! Let's hope i't works :fingers-crossed:
[Galaxy S III General] spykedsystem:
glad it worked for you,lemme know if that firmware also gets your phone back on track,if it does, don't bother flashing EMG or EMH..it will not work, for now. Unless you use custom kernels and older modems with them,at least for me.
[Galaxy S III General] Wess_90:
'Installation aborted' was the error (after 2sec) while flashing your zip. Tried it twice but again the error. Do you have any idea?
[Galaxy S III General] spykedsystem:
was that in Odin?
[Galaxy S III General] Wess_90:
No, copied to phone, recovery mode, flash zip from sd card. Do i have to flash with odin? Again in PDA sector and download mode on phone?

And no i did not back up my efs files (that will never happen to me again :silly: )
[Galaxy S III General] spykedsystem:
Wipe your phone completely in recovery(system/data/cache/preload and dalvik) then flash that firmware with ODIN in PDA. that should do it!
[Galaxy S III General] Wess_90:
completed. Unfortunately still 'not connected to network' IMEI didn't change.:confused:
[Galaxy S III General] Wess_90:
After that didn't work, i tried this. I had to root again(was not rooted anymore?) then i followed the steps after backing up my efs's. It gave the error 'unable to chown 'efs/nv_data.bin, no such file or directory'. then the yellow info on screen came back but different, see attachement. IMEI didn't change.

i copied back the efs files to the root with root explorer. yellow info on screen are gone but still no correct IMEI.. :crying:
[Galaxy S III General] phreakymind:
I have the same Problem here.

Downgradet from Ultima V15 to an older Stockrom via Odin.

I thought that it is no problem as i do have an old efsv1 backup created with efs backup pro 1.4.7 in april 2013 (.img file). But restoring doesnt work. Everything looks good, no error messages but it still got no imei.

i tried every step mentioned in the first post.

Flashed back to Stockrom (April 2013) to Ultima 15, flashed the Omega 49. Nothing helped. Delted efs directory content before restoring.

Faulty efs backup then?

edit: i tried to restore via efs backup pro 1.4.7 as the new version couldnt read the .img backup created with 1.4.7.
[Galaxy S III General] W@r10ck:
Basically i wanna sell my S3 i9300,unrooted having a stock rom but i was on mg2/mg4 as my last rom.So after unrooting & flashing stock rom i lost my imei :(. I tried rooting again and restore my efs backup but still the same. I havent tried flashing my cwm backup or back to the previous rom that is working as i think it should have no problem but it would defeat the purpose of putting it back to original & have the usual sammy update.

[Galaxy S III General] KnowledgeBroker:
This is a horrible answer - do you know anyone who has actually done this? Have a number to contact? Know how much? Know ANYTHING first hand that is HELPFUL - because if not then your reply is useless. Either be helpful, or don't post.

There are tools that can repair IMEI - but they are expensive. There are plenty of tricks to try to restore efs backup - I haven't had any luck yet restoring mine..

But I am sick and tired of seeing so many people post "send for repair" as if this is even REMOTELY helpful! Just don't post if you can't help!

The only things left I can think of trying is to odin ICS, doing a 4.12 odin full reflash didn't help.. efs professional doesn't work because my backups don't have the efs.img file in them.. restoring them with kTool doesn't do anything.. the only thing left I may try doing is decompressing the backup tar.gz files and manually pushing the files over somehow.. but even with an insecure bootloader it tells me I can't adb push while in recovery, so I may have to make a flashing zip file or something.

Again, I implore you ALL - stop saying "send for repair" in a forum about development - either be helpful or don't post!
[Galaxy S III General] JJEgan:
What a pathetic stupid post

>>>This is a horrible answer - do you know anyone who has actually done this? Have a number to contact? Know how much?

YES see previous multiple posts .

Who do you think has taken all the time and trouble to investigate IMEI/ EFS and right the guides just the guy you are slagging off .Same guy what answers multiple EFS/IMEI identical questions .

Yes you can buy a tool but that is beyond the home user and most what not be capable of using such .

Saying send for repair after trying the fixes is helpfully your answer it totally useless for the vast majority .

How about you getting off your winge bucket and building us all a EFS/IMEI fix
[Galaxy S III General] danarama:
Oi, this is MY THREAD. GET IT??? The entire thread is based on MY knowledge, which I CHOSE to impart on you! Read post 1 before jumping in with your pointless lack of respect and even more pointless lack of knowledge. I've read the users posts and as per post 1 - that is the only option left. Don't like it? Well tough sh*t! Some things are true whether you like it or not.

Now I suggest you butt out of where you've got nothing to add and where you're neither wanted or needed!

[Galaxy S III General] KnowledgeBroker:
It may be your thread, but do you know how many pointless posts you and others said "send in for repairs" as an answer? You aren't the only one "contributing" around here, but PLEASE think.. is your next post contributing to anything except your post count, making it harder and harder for people to find useful answers? How many posts in this thread say "send in for repairs", which isn't a technical answer at all, and wasnt after thoughtfully trying ANYTHING?

This is a developers website, I expect people to provide some level of expertise, not just the kind of advice someone gives when they don't have the answer.

You earn respect as far as I am concerned, and on a developers website it would be by being a good contributor, trying to be helpful, WITHOUT jumping to the last resort which is to say "give up". Yes, sending it to the manufacturer without first trying, methodically, every single thing you can, is giving up.. not something someone with some technical experience does easily.

Your very first post, which you gladly pointed to, single handedly says "don't post anything new, we are sick of more posts about the subject, the answers are here or easy to find" - but then also repeatedly your thread is the opposite of helpful.. you can't have it both ways. Are your posts just as bad as these "noob" people asking the same repeated question? If they are, maybe they don't like your answer of "send it in for repair".

So maybe I'll go post my post rather than ask for help from someone that doesn't know how.. because I am absolutely sure there are plenty of people that have more insight than the guy who recommends people give up(so many replies) before they've even started!
[Galaxy S III General] danarama:
Ha ha. Thanks for making me laugh!

Actually, I am providing my expertise. That's what the whole thread is about. I have not "jumped" to the last resort. I know what the user must do and I told him that. Get a grip will you?

Of course your solution (the only thing you can think of) which is already covered in post 1 can cause a brick so well done on your one-upman-ship.

Please keep ridiculous advice to yourself or at the very least disclaimer it. Dont be rude in future and THINK BEFORE POSTING.

If a user has tried everything in post 1 except "send for repair" then "send for repair" is the only answer. Also there will be some scenarios where we instantly know that is the answer. That answer was directed to the user for a reason! Why do 1 & 2 when we already know the answer is 3?!

And you're right, this is a DEVELOPMENT forum not a help forum so regardless of what you "expect", actually losing your imei is off topic!

Anyway, this ends here. It is not your place to judge my expertise and second guess the reasons why I post what I post. There are many answers here from me that are not "send for repair". I do not give this answer as a lack willingness to help. I give the answer in some cases (like this case for craigo888) to save time and not give false hope. I give it in other instances where there is a lack of acceptance that the fixes are finite.

If anyone has a new fix that has worked, even if not always successful, it can be included in post 1. This thread is organic. However it is not a place to try and belittle the answers of those of us giving our time to helping people. Just because its not the answer they want to hear, doesn't mean its not the answer.

Spend £25 on a EFS/ IMEI service repair is hardly a pointless post .

In fact many would be better of going straight to repair.
[Galaxy S III General] danarama:
Yes, as with the entire ariza patch issue. There are 3 options in regards to EFSv2 ariza users..

1) repair

2) wait for updated ariza patch

3) try zuluman patch.

These are listed in order of suitability

Anyway, lets end this pointless discussion. It's not helping anyone. The frustrations of one is not a justification to attack answers directed at others

[Galaxy S III General] KnowledgeBroker:
Well, for the topic of other things that can be done, I noticed many people had a lack of success with ktool and efs explorer.

I did have an efs backup, but it didn't have an efs.img in it, so using efs professional didn't help.. neither did copying efs.img(that I had from a probably corrupt efs folder) into the backup tar.gz.

Ktool resulted in a bootloop, even after fixing the problem, backing up efs with it, using it to apply it again..

The fix for me - do a total odin flash back to stock. That is bootloader, modem, csc, etc.. using s3 toolkit root/recovery/insecure boot image, reboot, install zarchiver to unzip the tar.gz backup, using es file explorer to copy the files into the /efs folder, then verifying the persmissions are correct(which doing it in android, without using a pc, the file permissions seemed to stay intact)

One problem I had was that I fixed the issue AFTER flashing a rom, so copying the files over, after a reboot, would fix the issue.. until another reboot. I believe this is because some roms write the /efs partition from the backup they did upon originally being flashed. In any case, doing this immediately after a fresh stock/rooted flash, the fix stays after reboot.

Many people who are complaining of efs issues have no backup, but many more did have a backup that they couldn't use - I had issues pushing the files with adb in recovery or while booted(which makes sense), so this seems like the most straightforward fix of those I have seen.

I don't know what the original issue was with my efs, I was running ARHD for weeks, no modifications of any kinds, and randomly yesterday morning I had "emergency calls only", and his "efs backup" in aroma didn't actually work.. so I would caution anyone who uses that rom to make their own backup just to be safe.
[Galaxy S III General] danarama:
Yes I agree. I myself have 2x tar, 2x img and 2x folder dumps just to be safe, all via different method's. I will not be caught out by EFS*

i9300 micro sd failure- now no network found

Ok so ive got a i9300

about a month ago (running stock, unlocked from tmobile uk to 3network uk)

It bricked itself whilst in my pocket.

So under warranty sent it to samsumg. And it was fixed which I only assume

was sds.

I received phone back. Got it unlocked to 3uk again.

My contract with 3 finished so I changed it to a sim only 3uk.

my 8gb micro sd has been playing up. Mounting/unmounting

and then wouldnt mount. And now nothing on the card.

I have no back up of efs.
