[Q] nv_data.bin missing, no backup, no hope? - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

Hi all,
I've recently converted from owning an iPhone 4 to purchasing a brand new Galaxy S3 4G (I9305). One of the first things I discovered was the XDA developers forums and the many mouth-watering custom ROMs available. Being unexperienced but adventurous, I attempted to root my device with CF-Root which not surprisingly resulted in a boot-loop. I was able to recover my phone, and as of tonight have my phone rooted successfully.
Here comes the problem though. Ever since my unsuccessful root attempt last week I have lost my IMEI data. As I was previously unrooted I never had the chance to backup my efs folder (as of course the phone needs to be rooted). Now that my phone has finally been rooted, to my surprise, upon investigating my EFS folder there isn't even an nv_data.bin file!
I have attempted to back up what remained of my EFS folder and remove it, allowing the system to rebuild it. Unfortunately, upon rebooting there was still no nv_data.bin file. After many hours of searching online both through google, the xda forums and some other android communities I have remained unsuccessful in restoring the phone-capabilities of my phone.
As my last hope, I am asking the community here if there are any known ways of restoring IMEI/EFS data, or more specifically the nv_data.bin and nv_data.bin.md5 files without a backup. My last resort will have to be to send the phone in for servicing which may or may not be very costly.

Very very surprising it does not boot loop unless wrong install .

Try one a factory reset and two a stock rom install before anything .

Unfortunately I've already attempted various methods and stock Rom flashes. I receive the same results, where my IMEI data reports itself as null/null after typing the *#06# code. I've also tried flashing just the modem from the stock firmware, again with no change.

There are some methods available for i9000 and i9100 but unfortunately nothing works for i9300.
If your phone is covered by warranty, install triangle away remove binary counter and flash stock rom for you phone.
After doing this return it for repair.

I just got my phone back because it isn't covered by warranty. I have a belief that Jellybean stores the IMEI differently then ICS. As I checked my EFS folder, its exactly how you described it. I guess we need to kindly ask someone that has rooted their i9305. To view their EFS folder to confirm this. It's just a thought that derived when i was searching my galaxy nexus. It has no the nv_data.bin in its EFS directory it installed elsewhere.

It's correct that the i9305 ROMs do not contain nv_data files. I even went as far as copying over a working phone's EFS folder then hex-editing in my own IMEI with no change.

That may be so on model I9305 but on a JB rom on I9300 the nv-data.bin folders are in the usual place .

Is there any news ? Somebody solved this problem? I have also Samsung Galaxy S 3 LTE, without IMEI and baseband version...(((
I rooted my SGS 3 woth ODIN but made a mistake. First attempt - I have chosen partition "PHONE" instead of "PDA" in ODIN and flashed it...This way I kolled my modem baseband and lost IMEI...

Has nobody in here bothered to read the sticky thread I created in the I9305 Development forum?
I created the PARAM binary IMEI fix ages ago along with a big guide explaining that this device has a Qualcomm modem chip and has a different efs structure.
I also created a full backup and restore guide using QPST Software.
See thread below for more details:

Hi guys, this issue has been resolved about a month ago when I returned my phone and got a new one under warranty. Somebody bumped the thread back up to the top.

Thanks a lot for your great job & help.
But in he topic you pointed there is requirement to have backup of EFS/ NV data.
Or it is already possible to restore IMEI and GSM connection without any backup made before?

Well I could have, if I broke the phone exactly 3 weeks later, but unfortunately your guide was not posted yet. Still it's good that there's one for anyone that suffers the same problem now.

lmao very very Lost if i must say so myself

QPST did not recognize my GT-I9305
I follow the instructions to set QPST working in my PC but when i arrived to QPST configuration and adding the new port as mentioned in the guide my phone shows enabled but not connected; same thing in software download , backup tab shows no phone connected.
i tried to do the same steps in different PC than mine but same problem.
i am asking is there any another driver to install in addition to samsung usb drivers in order to make my phone detected in my PC
by the way all new drivers was downloaded by the system but still the same problem
thanks in advance

[Q & S] Swapping IMEIs between 2 Captivate?

Questions and Suggestions.....
I just got a second captivate, this one WITHOUT a cracked screen!! Now i realize i could just teardown and swap the main board, or the digitizer itself, but... that would be too simple!
Or i could just call my provider and change my imei with them... but who wants to talk to their provider??
Or.... i could do something fun and learn, by cloning my phone. from what i understand, all i would need to change is my IMEI, contained in my EFS.. and i have several backups of my good efs, and could easily backup the new one.
Is it simply as easy as copying the efs folder over with root privilages? or better to do an ADB dd (data dump) then tar it and odin? or ADB push/flash....
Is there anything im not considering? Is there any real risk if I have my EFS backed up? Any other ideas? suggestions? discussion?
any neat/interesting things to do with a copied phone set?
I have mine dd'ed and ready to flash with heimdall(i don't think ODIN will touch the EFS partition, but Heimdall will if you put it in there) So IDK, I would talk to conexxion2005 or AdamOutler about this!
thats what i was thinking...
Yahh, Or contact Benjamin, I forgot his last name, but he made Heimdall
Just dd the efs partition and flash it with heimdall. Thats all you have to do.
Code:
dd if=/dev/block/stl3 of=/sdcard/sdext/efs.rfs
do the same with your new phone to make a backup of it. Change the name of the efs file so you dont overwrite it. When you get done, swap the serial number stickers. I didnt tell you all this. Its illegal
it's personal development for learning purposes.
This is why I value second opinions.
now to get 2 (active) sims for the same imei.....
they both have ICS RC3.1 on them ive had the one a few hours.
one with silver speaker mod, one with out. if you dont know silver speaker mod, GO FIND IT NOW! READ THE FIRST 4 PAGES AT LEAST!
this is what ive been dealing with for the past 2 months......
but it works just fine....
I dropped it a good 10 feet, but it was fine, 20 minutes later took out of my pocket to see this...
http://dl.dropbox.com/u/19201431/Images/cracked%20to%20****%20but%20works.jpg
Lol my sister's looks exactly the same!
Just flashed it yesterday, it's weird to feel all those cracks under your thumb, and it still works.
I'm not sure DDing then flashing it to another device will have the correct effect but it's worth a shot. I can do remote IMEI repair for the Infuse and Vibrant 4G but their EFS structure is different from the Captivate. I know for a fact you can't just throw nv_data.bin files around and expect the IMEI to follow as it won't. However, DDing the zone then flashing could result in the desired effect.
LET US KNOW!
How would I know for sure? By checking the about> phone?... Running ice cream sandwich so I'm not sure if the dialer codes will work
I wonder if any of this would help me with my borked IMEI? I'm on the network default IMEI (the one ending in 0000) and I really want my original IMEI back...
Any ideas?
Do you think it would help flashing to stock including CSC files? Then immediately booting into stock recovery to force it to apply this CSC?
I know it does some funky things in that first recovery boot.. Applying settings and such...

SGN N7000: Help needed with repartitioning efs to ext 4 and error mounting efs??

I have tried to find more about my situation but asking seems to be the only way since all the info is either scattered or not available!
For two weeks I've been trying to fix my note from this ics emmc bug which made me loose efs folder and I have tried several methods with no luck, so I thought that repartitioning sd might kill the bug, so I repartioned just (parts)7,9,10,11 and also went for efs part that was empty anyway thought it might clear bad blocks, although afterwards I flashed efsfix.zip from another thread on here somewhere, because of which network and everything works just no lock screen and power button dialog? And when I flash any rom stock/custom it says (in red) error mounting efs, I found a solution for that by using terminal emulator and commanding "mount", But gotta do it manually afer every reboot?
And my imei is not the same as under my fone, how could I manually edit the imei and insert original fone info?
Could anyone help or guide me to a link so that I can recreate efs partition to ext 4 and the sort out other issues?
Edit: info in-depth!!
Thanks!
Does anyone know how to create/recreate an efs ext 4 partition on galaxy note? Is there a command or certain way to mount efs part as ext 4?
without efs backup you have lost your emei. Unless you resort to illegal methods in most countries (expensive z3x box)
At this point, just go to Samsung and have them illegally legally restore it lmao, they somehow are allowed to do it.
Anyway, how did you analyze its efs thats corrupted, cause if you can flash gb from pc odin succesfully its not super bricked
Sent from my GT-N7000 using Tapatalk 2
recreate can be done by flashing gb with pitfile and option clear efs. Then you should get generic emei. Which stupidly is also blocked in some countries.
That emei stuff is so overrated by secret agencies.

Thanks for the reply baz77.
Basically, I wasnt aware of this emmc wipe bug when I bought Note, I got my rom flashing experience and knowledge from SGS2, so after like a week of purchase I tried to flash ICS stunnner on my Note with squeaky clean, but resulted in getting my fone back from samsung after being revived, took 3weeks to return.
At this point I still didnt know about the bug because I had assumed that my own doing caused the super hardbrick, till I flash a criskelo rom with a wipe and my problems started off with not registered on network, after that I have been krazily searching and flashing to have the fone working flawless again without having to send the fone back to samsung becasue of the wait and tiny chips n crack on my fone.
And I figured that efs is corrupted by googling and gathering info about my particular problem and everything pointed towards efs being corrupted!
I am really hoping for them release a fix and I can get my fone back working as a whole again!

Apparently, pitfile and efs clear option doesn't work, I tried GB with pitfile got the red 'error mounting efs' and tried stock UK ICS 4.0.3 from (thanks to) Dr.Ketan but Ive still got the error and no lockscreen and faulty power button?!? Plus:- Sim Network is gone :banghead: , i'll just have to flash that efsfix.zip and do the terminal "mount" procedure again!!! manually!
"Probaly Leagality issues there" I'll try the same pitfile procedure with rom from another country if it doesnt work then dont really want to but guess this fone's going back to Samsung for repairs before I sell it off.
Many Thanks for your help!!

I have the custom binary count reset, so they shouldnt have any problems with repairing illegally then?? With stock UK ICS 403 Rom from this forum!?!
<SAMSUNG><ASONG> From GT-N7000!
I thought each rom had efs file, not so sure anymore. download and install 7zip, open the tar md5 rom file with it and ignore the warnings. should be efs. img in there, if not best download one, same csc as you have, if you know what it was before it became corrupt. I think kj4 has one, so you can flash whole gb rom with options efs clear and the pitfile.
If that fails, then perform a factory reset with code, do this only from gb, *2767*3855# in dialer. That might force the efs to reset itself to generic. Should not be needed, but hey it cant harm trying on gb. note own risk
If that fails, flash stock ics which you had in first place and ask them to fix it.
You need them anyway to get original emei back, which is why I said best go there. However if you still want to try above could give you a working emei. Its generic test emei and blocked in some countries thought, so if you need to travel...

Hey baz77,
I tried the same pitfile method with a GB236 Rom built from HongKong and flashed it twice, because I read on this forum somewhere that in the event of errors, missing files and apps after a flash, roms should be flashed atleast once more to get'em fully loaded but unfortunately even that method failed to mount the efs part.
Afterwards, I was just googling for more solutions and I decided to download and flash another GB236 rom Open europe built (wipe version) from Dr. Ketan's stock rom deposites and to my joyous surprise there were 2 extra tar. files, one named efs.md5.tar, so I quickly got my fone in download mode and flashed the rom with pitfile and when that was done, I got the fone back in download mode and Flashed the efs.tar (PDA), CSC, Modem (PHONE) and for the first time in 2 weeks the fone booted up normally as it should with the welcome screen, working lock screen and power button dialog! pheeeewwww!!!
But the imei is still not the same as under the hood, but I guess since the efs part had been corrupted, my fones probabaly using the emergency imei, Im using Alliance v1 with no apprent faults or errors.
i'll flash the GB Rom and try the factory rest code method by you and if it works then dont have to go to samsung and if doesnt then i'll keep using the fone as it is for as long as I have it and keep looking for solutions, if nothing happens then i'll get it sorted from samsung before selling it.
Your help is much appreciated, Thanks baz77!!! :thumbup: :thumbup:

back then.. there was an application on playstore that can fix IMEI issues... its called GSII repair.
https://play.google.com/store/apps/...GwsMSwxLDEsImNvbS5oZWxyb3ouR1NJSV9SZXBhaXIiXQ..
It worked mostly on all phones that I have heard of.. including the Note's of my friends whom their IMEIs got toasted.
See if you can give that a shot bud..
Ps. by the way.. most corrupted IMEIs have a mocked imei of 004999010640000
Others said that they were able to restore their original IMEI by flashing to stock GB, root the phone and install Root explorer, after that, you need to go to /EFS folder inside your phone(thru root explorer) and backup first your orig ' nv_data.bin ', now if you see a nv_data.bak in there with a previous date different from the bin file, then delete accordingly the nv_data.bin and rename the bak file to nv_data.bin reboot phone and check if orig IMEI is back on your phone.
Now this isn't applicable if your bak and bin files for ( nv_data) are all on the same date though.
don't try this yet unless your willing to give all possible options to restore back your original IMEI. Don't forget to try first the link I showed to you at the top.
Cheers.

Hi Letters_to_cleo,
Thank you for the suggestions mate, at the moment Im on Alliance v.1 403 rom, and I have just tried the fix from your link, did the steps1 & 2 restarted checked imei and it's the same serial (#to#) as you have stated, then i tried the step 3 which indicated that the nv_data.bin file is missing from that folder.
I have already gone to certain extents to return the fone in its generic state, so it won't matter if I tried once more besides trying repairs on GB rom is probably much safer then on ICS builts as long as the fone doesnt die on me,(completely again!), I 'll try your 2nd method in a bit and report back after!
Thanks for the support!!:thumbup:
<SAMSUNG><ASONG>from<GT-N7000
yeah that app wont work if you dont have efs backup. It distills from original. bak file the emei, now with the reflash of efs, even before you had lost it. only generic stuff left.
you need as mentioned before to go to samsung to repair emei, or find a phone place that can do it. You can yourself but in most countries its illegal. You need z3d box or equivalent for that, 150$$$$ lol, I have seen people who bought it offer that service for small fee. But be careful as ot could be illegal in your country, even if its going from generic emei to original emei lol.
Oh and you are welcome, been there done that, with the efs stuff. Samsung fixed mine.
My help is free, now if another has this you know how to help them
After Samsung fixes it,stay on gb, root phone and backup efs on multiple locations(pc, cdrom, floppy disk, bank vault you get it) In future when you buy android do that first. How to is in dr ketans toolbox thread in general section.
edit efs backup is not in nandroid, nor titanium backups. In fact still to date there is not one solution that can back everything up on your phone.

Hi Enseven reporting,
@Letters_to_cleo, the methods you suggested dont work but thanks for trying to helping, i didnt find the bak file in efs folder but there 2 nv_data files, and they're both dated from Jan2011, renaming them just disable's the network and doent change the imei#, it remains the same!
@baz11, Yes mate, you are right this fone's going back to samung bcuz im not looking to $pend 150 on some box that I wont even use twice.
Im not really that fussed about imei not being as same on fone hardware, just as long the fone works, but like you said it probably is illegal to sell a fone with messed up serial no.
And on top of that fone's price would drop for having software issues, only wanted to fix it so that I could sell it on without loosing much $$ from the original price I paid for it, it'll be disapointing since Ive only had the fone for just over 2 months.
And I did manage to fix the welcome/lockscreen/power button issues by flashing efs.tar I got from that wipe version Open Europe Rom but even after the flash, it restore's the needed files but doesnt really prompt the features so I gotta insert this command through terminal emulator: "echo n- ON> /efs/imei/keystr" "sync"and factory reset, then the fone reboots normally with everything working but the IMEI ofcourse!
Wonder if your lockscreen fix works ive looked for it on your profile's statistic's tab but uable to find it, could you plz provide a link. Thanks
Ive tried all methods with some luck and no further progress apart from having to buy expensive equipment, so I guess i'll keep using the fone and looking for any miraculous solution till I resort to Samsung.
P.S: If they cant find a fix for the emmc bug by working on scripts , they should atleast invent a nano tech powder (gadget bug killer) to sprinkle on the motherboard, LOL!!!
because this problem goes way back, like another user said on here you could make a movie about now, and ithink it started off as a scifi now its a scifi/thriller, "shall I wipe before flashing & risk hardbrick Or shall I wait for samsung to pace up the support!!!
Thanks to xda and memebrs for being online 247 and all the support though!!

Hi En7,
Sorry to hear my steps didn't work on your phone bud.
I checked some forums here in XDA and I've come across this one: http://forum.xda-developers.com/showthread.php?t=1804117. (I'm not sure though if you have come across that link before or not).
It is for the S3 forum but there's a tool in there that you can try to download and run to somehow restore your corrupted IMEI. It's worth taking the risk I should say but who knows..any given tool/info is highly useful and it could be a clear shot in bringing back your original IMEI back right?
Cheers bud!
lol that cracked me up nano powder hahaha good one.
you found the lockscreen fix, its the same fix I found while back from some guru.
I guess you can change emei to original with someone who has such a box. Finding is not to difficult, just need to go to a shop that can repair emei. Preferably Samsung thought, Just go to a samsung service centre, or store where you bought phone. Best unroot and put stock firmware that matches your phones original csc, to avoid anoying questions. Just tell the truth you updated phone and emei was gone/changed and you want original imei back. Samsung can fix it. Note, this time dont use pit or clear csc. Its not needed anymore.
I searched hard and long when I had that issue with emei, wasnt without a backup able to change it back to original, other then Samsung or such a box.
It annoyed the crap out of me. I can relate to what you were going through.
Everybody is nandroid this titaniun backup that, apparently efs is the only thing not standardly backed up with any standard mainstream solution.

[SOLVED] Restore IMEI with absolute NO backup?

Edit: Solved by going back to Stock GB. Thanks everyone!
I've got a friend who got a new Captivate from the US. And he flashed CM10 right after getting it, without making a backup of the efs folder. Now, the efs partition is completely empty, and of course it says "Unknown baseband, unknown imei", etc".
I've looked around, but all the imei restore methods seem to require at least one efs file. However in this case we have none. So, is there any way to restore the efs/imei? Maybe mounting it to the pc and running a file restoration software (might sound desperate, but we are).
Also, I have another captivate (this one is mine) with the efs. Would it be possible to modify my backup to use his original imei and then restore it in his phone?
Any ideas are welcome. Thanks in advance.
Installing CM should automatically backup /efs to the sdcard. Look for a folder called "backup." Also, flashing to stock can sometimes resolve these issues without tampering with /efs
I can't give you a 100% guarantee, but the two phones that I've had to recover IMEI's for both regained the efs folder contents when I flashed to stock GB from an ICS or JB rom.
Waiting 5mins inbetween postings sux.
The easiest way I could find to restore my IMEI was to re-flash back to a stock (in my case it was a rogers rom) then go forth from there. Like it was mentioned above, CM9/10 save the efs and restore it after flash. I lost my IMEI while flashing Helly and was frustrated at reading the "fixes". It was just easier to format, reflash stock then go back to CM10 (Which I'm running now and it's great).
Thanks for the replies.
Apparently, he tried to flash CM9, and in the process he thinks the internal memory (/sdcard/) was somehow wiped and now he can't find that folder. I told him to use recuva or something like that to try and get them back, let's see how that goes.
But in case he can't recover that folder, is there any other way? Maybe mounting efs partition on the memory and using recuva then?
He really has bad luck...
Well, there really is NO backup. I can't find the efs backup on the sdcard. Even tried with Recuva and there's nothing there.
What's funny about it is that there's no files in the efs partition, yet the df command says it's full. Any ideas?
As a last resource thing, I was thinking about using the efs from MY captivate and see what happens. Thoughts?
I really apreciate any comment!! Thanks in advance.

Just do a search on xda, there are losts of threads than can help you work through this.
I was able to restore my IMEI using this method:
http://forum.xda-developers.com/showthread.php?t=1264021
I did it via the terminal emulator on the phone.
I didn't have a good backup of my original /efs folder, either.
it just happened, that my solution for restoring imei on sgs3 i9300 came by installing Android Revolution HD rom. Maybe it happened because it's based on stock. You should try, maybe it will help. :good:

[Q] phone refuses to read sim

I know there is another thread on this but none of the tips resolved the issue. so today i flashed cm10 with devilkernel and the modem got wiped. so naturally i flashed a new one. It said it flashed but didnt work. so i wiped it and tried another. this process repeated for 3 hours and my friend rhine, who is highly skilled with this, and i together could not get anything to work. there is no lock out message but once it said safe mode although that went away. thanks in advance.

Have you checked to see if your IMEI is correct? I haven't heard much about it recently but when Jelly Bean first came out people would randomly have their EFS folder wiped when flashing to JB. Compare the IMEI listed on your phone under the battery to the one listed in the settings menu.
If they don't match then your best course of action is to use a one-click and take your phone back to stock which should restore your EFS folder. I would suggest then making a backup of that folder and then move forward with flashing as you've done before.
Some people say that removing your sim card during the flashing process will help prevent any issues but I've personally never had this problem.

[Q] Help me ROOT my Galaxy Note!

Hello,
After coming back from holiday, my phone suddenly stopped recognising my SIM. It see's a SIM so I no longer get an (Insert SIM Message) but I can't do anything with the sim. This is what I see.
Due to this problem I tried resetting my phone to no avail, I then stumbled upon this. I thought that this was fantastic, I could fix it without going to a store or whatever.
On my quest to root my phone for the first time ever I used a guide from the reliable How-To-Geek. I did everything the guide asked me to but unfortunately my adventure came to a halt when 'SuperOneClick' kept freezing when reaching step 7.
I have never rooted my phone so I really don't know where to begin, your help would be greatly, greatly appreciated! :good:
P.S (I have never rooted or ROM'd this phone before?
Here is what you can do
Which model is it ?? International or is it a locked network ??

Hello, do you mean for the SIM? It is the exact same as the screenshot of my settings in the first post. This is because I didn't manage to root it yesterday
The phone is completely fine apart from the SIM problem, that's why I want to root it
The __ONLY__ Current method you should be using to root is the philz kernel method. do not use any other method.
Please go to the philz thread.
PM me if you need more help later.

Thank you very much dude,
I am slightly confused by the terms used. As you can see from my thread, I initially tried using SuperOneClick which seemed simple as it just involved installing apps on my computer and clicking 'Root'.
Currently on my phone, I don't have to backup anything as I just reset it a couple of days ago, it has its stock rom (I believe that's what it is called) Would I have to install a custom ROM or something to root my phone?
Lastly, is this the thread you are talking about?
Thank you very much again dude

Super one click anything is either a lie and bull**** or simply not for this device
Yes that's the correct thread
Make sure to find the right one for YOUR ROM. Read the instructions carefully. No you don't need a custom ROM.
Easiest way to to flash it from stock recovery with the philz file on your external SD card if u have one

In your system settings you will go yo about phone. Match the version there to the Phil version.
I still don't get why you are rooting to fix this...
I am not sure who told you rooting would fix this...
You went on vacation and came back and the sim didn't work
Did you try removing the sim and reseating it in the phone?

Look at the original post. A user had the same problem and his solution was Titanium Backup Pro, he used it to clear user cache or something - this made the SIM work again.
I've taken out the SIM and everything, it works on other phones, just not mine
Lastly, about matching the version on my phone to the one on the thread:
Do I match the baseband version/Kernel Version or build number?

you match the kernel
Really man you MUST read the instructions in the philz thread its very clear.
Well you can try all that, I personally if it were my device would flash philz (safe kernel), boot to recovery, and just do a factory reset and see if it works... but I would only do this AFTER backing up my EFS using Ktool....
ggood luck
but if you want to try clearing cache etc first, no harm done of course
Just a side-note: regarding your links, etc that you post in the OP - I won't read those. I don't think other reputable members here will either. No offense please. I only trust sources on XDA, not random websites. If its not on xda, as far as I'm concerned, it is either incorrect or doesn't exist (i will act blind to it).
The Philz kernel for the Note is easy to find via google. Look either direct for the kernel or look for a PA installation guide and skip the odin option.

There is only one root account on a galaxy note, so it is the one-and-only-best.
If you want to root your device read Dr. Ketan's thread (search for it, good excercise for your brain).
And: best rom xyz posts or threads are against XDA rules.
Just read it: your best Rom thread yesterday was closed. Repeating this won't help...
