restored lost imei but still no 4G
I'm hoping someone can help me. I recently lost my imei (went to zero), I re-injected it using the PeoplesArmy method, but it didn't restore my 4G. So the imei is on my phone but my data service is stilled screwed up as I"m only on EDGE. I was wondering if anyone knows of a fix for this. I went through the steps layed out by the Peoples Army but it didn't work. Thanks in advance for any help.

yea i guess they rooted my phone and used certain commands to fix my efs folder .. if you loose your imei no. its because of corruption in efs folder . you can only acess it if you have root acess in your phone ... hope you can understand what im saying

The EFS Clear option from ODIN isn't the same thing as erasing the EFS manually ?

I have not made a backup and my IMEI and Baseband is unknown after flashing a ROM on Samsung i9070, is this tutorial valid for I9070 ?

Hello! I need help so bad , my phone doesn't recognize any SIM Card and my IMEI is empty.

I followed this guide with no success. What am I doing wrong?
I have a lot of EFS backups, so I don't know what's the problem. I even tried to copy my EFS backup content to the root EFS manually, but it didn't work. I even used the HC-kTool to make a restore... but everything seems useless. Is there something I am missing here?

I found this alternative http://www.unlocksamsungonline.nl/in...?page=download but I don't know if this works, what do you guys think?

I'm sorry for my bad english and thank you so much in advanced!!!
Have a nice day.

i have imei showing null( most the time) imei-sv showing unknown( most the time) in settings. have been searching high and low for a fix and tried everything ive com across. efs repair ro gs2 repair. the manual 9 steps in this thread samsung tool installing other roms modems etc etc to name a few with out a fix yet............. there has been odd occasions that the phone displays the generic imei and then shows baseband etc etc as normal on phone, but unable to make network connection.....allthough there have been 2 very odd occasions i have had network connections. once able to make a call. and another recived a text that was sent days before to me.. ive noticed over about a hour the phone was showing signal bars on off on off on off etc about 5 seconds on average for a hour or so yesterday.... im thinking its more a hardware problem with the baseband chip. is there any way to check/test if this chip is operating properly or not?

Hi guys. I had my phone working properly this morning, and then all of a sudden I got the generic IMEI (0049 etc). No apparent reason at all. I tried restarting my phone several times but nothing helped.

First I tried doing the 9 steps described on this thread, since I had a backup of the original EFS folder on my sdcard (the files were dated from 27/07/2011, which is exactly when I got my SGSII), but after step 9 and rebooting the phone I got the welcome to android screens as if I was booting the phone for the first time, but still had the generic IMEI.

Maybe worth mentioning as some others I didn't have the ".nv_data.bin" file, only the ".nv_data.bak" file both on my original efs folder and the backed up one.

After that, I tried using Galaxy SII Repair app but it didn't change anything either.

Then I found the tutorial on this post (http://forum.xda-developers.com/show...7#post39100837), which I tried doing both from terminal app available on Market and from the adb on my PC. Through terminal I couldn't do all the steps, but from my PC I could (I had to force a recovery reboot to do some steps, though). I finished doing all the steps, but even like that nothing changed.

My current status is I have the generic IMEI (0049...), I can access the 3G mobile network, but status shows as "emergency calls only" and when I try to call some number a message on the screen appears saying I'm not registered on the network.

I have gone through all possibilities I have read and none made my IMEI return to its original state

Any help would be gladly appreciated.

I think I'm lost

I tried using Ktool to recover my IMEI using an .img that was created last year when I began changing ROMs and stuff, so it's obvious it was working back then. The phone even popped up with the pattern lockscreen I wasn't using recently, but with the code that I used back then... but no IMEI change, still the generic one =/

One big problem, did the same as said in OP.
Deleted the EFS folder after backing it up through Root Explorer, but as soon as i press delete my phone restarted and then it is struck at boot screen for ever.
Tried reinstalling the roms from recovery mode, but never went through the boot screen.

I think i lost my EFS folder and phone can get that to start again

Any help guys, don't understand what to do next.
