Hello, I own Galaxy S2, after I tried to update firmware to JPKI1 ( Downloaded from samfirmware), the flash went ok but after that, I noticed the Signal is gone, IMEI and I CANT do any reflashing either to stock or custom, I used ODIN to do the flashing procedure, each time I flash a Firmware nothing happens the old (JPKI1) version still there, I'm confused what to do now DIY or Service center?.
Regards.
sounds like you may have nuked your efs folder.
If you ment to write I noticed the Signal is gone and the IMEI
Hopefully you have a backup

Can you flash a new rom & rooted kernel via odin
then look to see what you have in /efs
If you have any backup files under /efs, say /efs/_nvdata.bak you may be in luck (I was)

Well, I tried to flash another kernel and another rom but the weird thing is after finishing the flashing, nothing happens at all, the old version is there, even if i do a data wipe, the data doesn't wipe at all, every thing is still the same, thanks for the reply.
BTW: I haven't found anything in efs folder.
Regards.
Currently on Checkrom XWLA4 2.3.6 with Speedmod kernal.
Last night I performed a Titanium backup and a Nandroid backup in preparation for an upgrade. I had previously performed an EFS backup sometime back. I didn't perform the upgrade, just completed some backups. Anyways over night something seems to have gone wrong with my phone. I wake up to find that it's showing there's no SIM card detected and then when I checked baseband version and IMEI both are showing unknown as well as a bunch of other fields.
I've tried a number of ways to restore the EFS folder. I've tried GSII_Repair, EFS Pro 1.9, kTool, and a couple of manual methods. All of which give the same result.
Some strange things that I noticed, I have an EFS folder inside of an EFS folder. The /efs folder seems to have less files then the /efs/efs folder. Also /efs/efs folder was the fold that had the .nv_data.bak and .nv_data.bak.md5. Not sure if its suppose to be that way.
Wondering what the best way to try to get my phone up and running would be.
Thanks,
Lu.

The problem:
(a) You performed nandroid backup in CWM recovery while your phone was connected to the charger. This is a known bug of almost all versions of CWM recovery.
(b) Baseband missing means that your Modem was wiped off which happened as a result of the bug in (a.)
Further Explanation
a. this has nothing to do with your /efs folder
b. If baseband is missing then the phone can never read your IMEI, hence no network
Possible Solution
a. Download Modem (CWM zip format) of your choice. If you already have a modem then, skip to next step
b. Disconnect your phone from the charger
c. Boot to CWM recovery
d. Flash modem.zip you downloaded
e. Reboot phone
check your phone info after reboot (give your phone about 5 minutes to settle down), your IMEI, network etc should be back now
good luck

it was definitely plugged into my usb port charging at the time. just tried what you recommended and still the same issue. i wouldn't be surprised if everything that i tried today with the efs folder made it worse.
any recommendations? would it help if i tried a fresh install of xwla4 (2.3.6) or something newer like xwlpg (4.0.3)?
really need to get this fixed. any info or step-by-steps are greatly appreciated.
thanks.

You shouldn't have messed with your efs partition after the issue came up. it's suppose to be the last solution and not the first one.
ok.
try this:
-Remove your SIM.
-Reboot to CWM recovery
-Flash modem
-wipe cache partition
-wipe dalvik cache
-reboot phone
-Allow phone to stay for 5 mins.
-check your phone info, check IMEI
if both are back fine, just reinsert your sim and continue normal life.
let me know what happens

Not sure what happened or how this happened but while I was retrieving the information from the About Phone screen the baseband was showing unknown and then once I glanced back down to get some more info, it just appeared and within another few seconds I got my IMEI and cellular services started working!
Thank you very much kind sir! Greatly appreciated!

When you have this kind of problem, messing with /efs should always be the last solution and not the first one.

in your own case, where baseband and imei was missing, changing anything in the efs comes last because, if it's other thing related, flashing modem , firmware and things like that should fix the problem.
Then the last thing is messing with /efs partition.
Why, because, efs partition is not touched during flashing of ROM/firmware. It contains sensitive files, and should only be modified as last resort.

I did a back up on sd and pc. Before. I had only flashed from rr 2.6.1 rom to a jb rr rom after a few days of not changing any thing it came up network locked enter code etc. Whilst out driving so nothing I changed iko. Now it still changes imei but I have a stored working backup so I jus restore that and reboot. Would a modem and rom have to be compatible? I've never changed my modem do I need too and is it flashable? thanks
I only have these problems cos standard isn't different..

Or manually repair your efs folder by following the tutorial here: forum.xda-developers.com/showthread.php?t=1264021

Hi guys, well i managed to somehow ****up my efs folder and it now says no baseband and imei/imeid.
I have searched and searched for but closes thing i was able to find was using nv writer to write my old imei back onto my phone. The problem is when I *#7284# I have no option to choose DM + ADB + <cant remember other option> I only have PDA or MODEM option.

Can you try kTool?
K-tool does not work, which is why Prodigy got me to type a command line in the terminal which backed up my EFS folder manually. Now I have an EFS.IMG This is why i put up the THread Because I knew it was soon someone will be bound to stuff up there EFS.. Which is WHY WE ALL NEED TO BACK UP OUR EFS ASAP before we start modding
But as for recovery its hopeless? Can a box be used to restore the imei? Anyway i can write my imei using nvwriter after somehow solving the problem of not being able to put my phone into diagnostics mode?
Argh! I am going insane, this is looking like a one dear mistake!
I had the exact same problem. Tried MANY things, with no luck. If you got yours from Optus less than 30 days, they will give you a brand new replacement phone .
Try to install a stock rom like 4.0.4... that worked for me on a S1 with the same problem and fixed it!

I have the same issue although it happened to me when I flashed a rom to ROOT my device and I didn't back up the EFS, now it doesn't read the SIM/Network and my Baseband & IMEI are Unknown.
I have tried re-installing the stock firmware etc but still no success...
Anyone have any suggestions?? Or at least how I can update my device status back to normal a pose to 'Modified'.. This was I could maybe submit it through warranty repair.. I have tried to reset my binary count with triangle away (before unrooting) but no success as.. The only thing i've managed to be able to do is unroot my device..
Please help!
Thanks...:fingers-crossed:
if you dont mind about the reading , u can still use your phone flawlessly.. and try the trick "oh im not sure , oh i dont know" and get one replace or u will need jtag i guess.. or maybe ( not sure if it work ) get someone else backup efs and find a way to put your imei in and push it back to your device.. and then repeat same procedure with your original imei ... if u cant remember , take a look at your box.. well..i am just suggesting..not sure if it work...
to get rid of modified , go download sammy official release for your telco or country , flash it with odin but the binary counter remains... good luck to u..

I read last night that if you flash the original OTA over your phone it will re write your IMEI number and if Telstra's one is not out just use one from AT&T or Optus etc..
So you can make a back up of your EFS and go from there with re rooting and applying a new baked rom.
Either way if can work or it can not. i see no harm
Anyway here is the EFS taken' just now
you should never share your EFS folder with someone else. Due to the fact each imei is unique.

Hi,
First off I'm new to this forum and this is my very first post...
I by mistake formatted my SD card and erased all the CWM backups of my stock Rom. So, now I'm stuck with a custom Rom. I was hoping if someone could tell me where i could find the stock firmware for my model. Or if someone could send me their stock Rom backup if possible.
I've tried Sammobile and it said that the file doesn't exist.
I tried stock Rom flash-able via Odin which after flashing got stuck at booting.
Please,help.

It's common to bootloop after Odin flash of stock rom. If the flash was successful and without errors then just need to boot to recovery and reset after flash.
Done that already.

Hi
Thank you for your response.
I did that but then itself but still it would hang at "Rogers" on boot, and then if I leave it for a little while longer the display would turn off.
Also, my EFS folder is corrupt. Is there anyway to restore the IMEI no? I was trying it a post on this forum on how to unlock the phone and ended up corrupting the EFS folder.
Since this phone isn't available in my country the Samsung cannot provide service to me, that's what they said, so this forum is my only hope.
Which firmware did you flash? So you tried to do this http://forum.xda-developers.com/showthread.php?t=1595756 instead of this http://forum.xda-developers.com/showthread.php?t=1860003&highlight=bit-flip hmm? Is your IMEI missing or is it 0049...?
You might find something helpful on this thread http://forum.xda-developers.com/showthread.php?t=2535384 I believe you are suffering from the reboots because of the messed up EFS partition. The 3rd post in that thread explains what block the EFS partition is at. There is more info about this issue here http://forum.xda-developers.com/showthread.php?t=2471421 - I think those adb commands might work properly if you change the block to the one in the first link since this one is for another Samsung phone, but pretty sure it's the same deal if you have successfully flashed the correct tar file to restore to Rogers stock software and a reset didn't fix.

Hi,
First of all I apologize for not responding sooner.
I flashed the stock rom for SGH-i927R from the sammobile website. I tried reset, I tried flashing it again but, no use. It still goes into bootloop. Could you tell why it goes into bootloop.
Thanks for the tips on restoring EFS folder. I'm using CWM recovery, If it works with CWM also, then I'll try the links.
Thank You.

Kies isn't going to fix EFS issues like this.
What happened with the adb commands? Just saying no result is not very descriptive or helpful. Was there an error message? Were you not able to get it to recognize the phone? Issues with drivers? etc

Whatever adb command I tried it said, "*comand* not found". So I checked if adb shell was working with cwm and it was(i tried rebooting).
there were no issues with drivers or getting it to recognize the phone. Just that those particular were "not found". Do you know what it could mean?
If you are in CWM and run

and it returns the device serial then you should be good. What commands are you trying that aren't working?

So I searched online and saw some tutorials how to root and install costum ROMs.
I read few tutorials to be sure how to do that and after all went good and the ROM installed, One problem has rised: NO SIGNAL!
so I wiped all and installed a ROM STOCK.
After that the signal came back "half way". It's showing signal bars but I can't call to anyone, even after calling to my provider...
I just don't know what to do. Please help

well these tutorial you've read were either very bad or you haven't read them correctly, because probably you missed the important step of the efs backup. see therefor the stickies thread or the thousands of similiar questions here in the q&a.

That is your backup flash with odin
( When you flashed a custom rom it probably backed up your efs some roms backup by default)
I would just backup your efs you have at the moment just in case you have problems flashing. You will then be able to return to how your efs is now even though it is not fully working..
Or try this app >> https://play.google.com/store/apps/details?id=net.hellcat.droiddev.ktool <<
The phone has to bee rotted to use ktool?
I also understand from the link you did about the EFS that there are two types of base bands and if I have an efs backup that I did on V1 baseband so I can't restore it on a v2 baseband, so my conclusion is to get back to 4.1.2... correct me if I am wrong

good that you found efs backup
yes you need root. or you use the recovery philz touch to restore your efs (then you don't need root, but a custom recovery).
well samsung roms based on 4.3 need efs v2, so you have to go back to 4.1.2 to restore your efs v1 backup.
if everything is working again, I would suggest you to use oding to upgrade to 4.3, because then everything should be updated correctly (but keep your efs backup, and make another one, just to be sure)
then you can try out again custom roms based on sammy 4.3
So what is the best option to restore it?
Because before I tried (while 4.3 stock rom was installed) the flash it with Odin but Odin always crashed when I was uploading it to Odin.
With kTool I tried before but when I am clicking on the button it says that it restored but he didn't asked for directory, when do I need to put it?
The same story with phliz, I also tried with this and he don't asks for directory, only asking whan the ending if the file-tar to bin...

Just extract the efs.tar and copy its contents to /efs.

Where is this folder located? I can't find it
and does it for xTool and phliz recovery destinations for teaking the recovery from?
Edit:
I found the /efs. I dind't know that I need to use root explorer...
I exchanged the files with my back up and suddenly instead of 0049 IMEI I got 0000 IMEI.
I tired also to flash a modem and also didin't work...

Hmm... try installing another EFSv2 modem, then do the /efs copying part again.
Suddenly after so restarts, the IMEI got back
But... The SN now is 0000000000
You'll need to correct the permissions of the files you've copied. Try searching for someone who already did this and duplicate what they did.

Ok,
I tried something new. I flashed a new modem, backed up a full backup and then installed a costum rom 4.3.
the IMEI GOT BACK! And even the SERIAL NUMBER!
But I think the serial number is not good because he has 16 or 17 (I don't remember) digits (numbers and letters).
But still i have signal bars but can't make or receive calls he says: "No registered on network"
For the finalle, I tried ARIZA patch but he Is stuck on 0%...
here I stopped, I really don't know what to do.
Don't use the Ariza patch once you've got your IMEI and SN back. Maybe try flashing a new stock version of Android with a EFSv2 baseband so as to not go through the copying fiasco.
