Hi All,
After flashing new ROM, my first time, the device couldn't connect to the network due to missing IMEI.
I don't know how and why it was deleted.
I have tryied to revert back to the Stock ROM and the same.
I have no support from my service provider because the device is hacked...
Any solutions?
same case happened to me
hi there, just the same thing happened to me when I newly bought samsung galaxy S2, I did many trials to find a solution and a lot of internet research but I could not find any, and a lot of new flashes.
At the end, I re- installed again a stock ROM and went to the service shop where it is still under guaranty, the guys there did not know how to fix it back although they have contacted the VENDER (samsung firm), and at the end they replace it with BRAND New one, I was lucky.
However, when you get a new one, you have to back up a directory called "efs" using root explorer application (have to buy it from market),while u must be rooted, they folder includes the imei data needed, and if you have it already back it up some time back, try to restore it and may be you will have your imei back, (i could not dare to try this after i got the replacement).
My cousin had this problem when he flashed lite'ning rom 6.1 on his new galaxy s 2. I flashed it back to stock XXKH3 and imei and baseband returned. Tried flashing back to 6.1 and again went off so back to stock and everything working fine.
Try restore IMEI technqiues (part of my reserches atthat time):

Using the root explorer method I'm not sure you will be able to restore the IMEI if you corrupt the /efs folder. Have a look at this!
Dude, read the f**king rules!
This is the wrong section, and you obviously haven't even tried to use the search button.

If your /efs directory got erased due to a flash.. Short answer: Without a backup you cannot restore it. A support request from samsung maybe, but unlikely due to the modified nature of the device.

If only. It's funny how people lose their efs folder then come complaining and researching afterwards. All they have to do is simply back it up.
Return the phone to samsung under warranty and hope for the best OP.

for me, after installing Lite... Rom 6.1, i miss my IMEI, but after installing first rom(with three files!) of middle east, its back to me!!!
Lost IMEI
Are you sure the IMEI is realy lost? sometimes when the modem ****s up or compatibility issues.
I think maybe you should download only the modem which corasponds to the rom you are using, ie, use KH3 modem if KH3 ROM etc.
Give that a try my friend...dont forget to read the instructions in the other threads about the use of odin, I know this is not the appropriate place for this thread but there is no need to be agresive towards people who are learning the ropes
indeed try to flash back to stock rom and then root Backup your efs folder then try flashing a rom again.
i got this also that my Imei was gone flashed back to stock and it was back again.
Someone knows how to reproduce this?
I already have an efs backup but want to try to get a new sgs2 (yellow tint prob).
Cheers
Same here, have had Litening Rom 6.1 (for a couple of months already) and IMEI gone since this morning. The phone can't find the network anymore. It also has problems booting up sometimes. In some cases I need to pull the battery and boot it 5 times in a row before it boots past the first screen.
I guess I need to downgrade as well. (Or upgrade to the latest Litening version, but I'll first downgrade to the original firmware.)
on newer phones they have made it harder to fff up your imei the efs directory no longer exists and the data is saved in a private partition instead..
that is the way it is on my wifes galaxy s gio that i just setup..
just info for thought.
so i have been searching and searching for a way to use adb/hex editor/some config file to simunlock my acer liquid e which is locked to rogers. I have recently unlocked my samsung tablet buy using a hex editor to change a value in nv_data and that worked. Have also unlocked my girlfriend's htc evo 3d (also rogers, all my devices are from rogers) using a config.dat file generated from the imei. Sifar i have come up with nothing to unlock my acer. Has anyone found wheere the networklock state is, or figured out another method to achieve this?
Reserving second post for answer (if ever found)
probably you need to look at http://forum.gsmhosting.com/vbb/6320142-post1.html
I have already looked through this thread, and am hesitant to attemp this particular method for a few reasons.. One of which being i can hardly understand what he's trying to instuct the user to do with those instructions, another being i have spent hours and hours flashing different roms and tweaks, and toying with the roms and tweaks to get my phone to where it is, nice and smooth, stable, etc. And it appears these instructions depend on switching back to a stock firmware.

What? Didn't you change IMEI after full flash? You have to change your imei to correct one.
I want to change imei sir but i dont know how . did u know how to?
Whaterever you do don't install any room that needs repartitioning.
If you start playing with partitions you phone will never be the same and the chances of losing the IMEI are like 99%.
YOu can restore the IMEI with 5eirom tool but its not the same and everytime you downgrade or upgrade IMEI will be lost again.
DO NOT REPARTITION YOUR PHONE. no matter what other might say to you.
I you want a stable rom with all function working and without issues, I'm afraid only stock Froyo.
After thousands of rom flashes and twice my phone went to repare dure to lost IMEI I have again IMEI issues and phone is like ****.
Theres no rom like stock froyos for our phone.
If you really want a fully working ICS or JB consider changing phone.
This is my honest oppinion and the BEST advice someone can give you. Now its up to you!

But before im always use cm10 by oguzhan working well sir. my phone came like a sucker when i click instal repartition systsem of optimus l7, my phone always reboot every 5mins and i can't go back to stock bcoz always failed
and i found the solution i need to do fullflash package via linux (restore mmckbpl and the right data partition) after that my imei was changed and i didn't backup it. go to official 2.3 but i can only get edge signals i cant browsing. try to enable wcdma only but always no signal. last experiment i upgrade my phone to official 2.3, but it sometime ask sim network unlock code

I din't quite understand what you meant.
Anyway, downgrading to stock froyo its easy.
If you repartition before, you need to revert to stock partition and then copy the dload folder to the internal SD (very important, must be internal SD)
I would suggest this, is your phone still on guarantee?
If yes just do what I mention above, then upgrade to any stock GB and if the IMEI is 0 take it to repair.
When comes back, the do whatever you like but never repartition again.
Repartitioning is the stupidest thing anyone can do to the phone and who advise it should clearly warn the risks as the biggest one is losing the IMEI.
To correctly restore the IMEI only changing the main board of the device, period!
If you touch the partition of your phone ytou will never be able to restore to REAL AND ORIGINAL stock partition, no matter what anyone tells you.
Please that recommend this should be liable for the damage on the phones as no one, clearly states, that the you will have almost 100% probability of scramble the phone!
Twice got the phone repaired under guarantee now guarantee is over and I have this completely messed up.
Been there, done that....3 times!! So when I tell you this my friend, is with experience and awarness not because I have heard other talking.

I have pink screen can you restore my IMEI on stock GB?
Tell me how to do it becuase everytime I try to do it crashes the rom and I have to start all process of downgrading upgrading.
PLease note that I'm on this for a while so I have a little experience
Also, both times that went for repair, it cam with a complete new interior (board) and obviously new IMEI.
If there is a simple way of restoring the IMEI why don't the technicians of Huawei do it?
Or They have a thing for spending money is changing the hardware?
The second time I speciafically asked not to chnage the hardware and respective IMEI as I would have to again pay for an unlock code. They sent a reply saying the IMEI is saved on Factory and when lost it cannot be restored again. The only solution to correctly do it is by change the board for a new one, and by this you will also get a new IMEI.

Hi all
Wondering if anyone can help me.
I rooted my phone and installed the Cyanogen lollipop ROM for my device (910F, international, UK, EE). Everything's fine, except I have no IMEI number and so can't access the mobile network. The baseband is unknown, as is the IMEI, but I CAN access wifi. I KNOW this was stupid, but I didn't have a backup. I can see the IMEI number from the back of the device, it's just a question of getting it back onto the phone. I've spent the last several hours trying to fix it, but am stuck. All the searches I've done have come up blank too - none of the numbers I've found to go into command mode work.
Any ideas?

Thank you.
Are you still having problems with the IMEI? I thought you got a replacement device? Try flashing a stock UAE ROM. What model do you have, like, do you have the G935F? Find out what CSC version your device was shipped with. Download a stock ROM that specifically matches your model number and region (csc).
Lastly, an advice, if you allow me to; Better stop playing around with custom ROMs, kernels and mods. The stock ROM combined with root and Xposed is running perfectly. Higher scores on AnTuTu Benchmark show no real life difference in performance. In fact, the only reason a custom ROM or Kernel achieves higher scores is almost only because they have "dynamic file sync" enabled. Enabling dynamic file sync can push your AnTuTu score by up to 30,000 points. You know when you need dynamic filesync? When you or a service move(s)/copies files from/to the storage. It has no effect on fluidity or smoothness.
I've been rooting my devices since my first HTC Dream. The S7 Edge is the first where I didn't need to even root it. I've been using it for three months now. No root, still the original ROM it came with. Never even had to wipe it. Only things I did was buy Adguard and Package Disabler Pro. If you do this, you're gonna stop messing around with it and start actually using your device.

First of all thanx mahn for your support.
as i told u i had completely stopped overclocking after that incident
This time i had installed kali nethunter. After somedays i finally made up my mind that i shouod not even root keep it fully (literally) stock. But i had tried already tried ur method no luck.
As u told after flashing with correct csc phone reboots then enters stock recovery and says dm verity check tree bla bla..
And need to check drk
I never faced this kinda issue in any s series i had owned.
Thats why i was bold enough to root but ended up like this.
Anyways thnx a lot.
In case you haven't, try this method. If it doesn't work, fill out this form and wait for a response from the owner.
