Lost imei number and can't make calls, search for networks or anything

Hallo! I have a problem where mobile connection doesn't work. When I try to connect manually it doesn't work it just gives me an error with no details in it. This happened after attempt on installation of Mackay kernel it worked but I noticed the mobile connection was dead after a while I ran a restore but stil the same problem. The efs folder is empty with a lost+found folder there is also nothing in that folder. When I click manage mobile contract it tells me that I need to put the SIM card in but it is inserted. HELP!!

Anyone? Please help me!

Is your IMEI still intact or does it begin with something like 0044?
(If you don't know where to find it, go Settings -> About Device -> Status)

Did you ever do nandroid backup before? If yes, it contains also the efs folder.
BTW, if nandroid backup was done with different ROM, kernel or CWM version, don't try to restore it with Mackay kernel!!
You must flash as furst the same ROM and same kernel and use the same CWM recovery version to successfully restore your nandroid backup.
Otherwise, you could flash some stock firmware and imei usually returns then. People report that Gingerbread JVU usually restores the imei number quite regularly. If your current ROM uses different partitions than stock firmware, you may have to flash also the PIT file to make step back to stock with success, PIT file will do proper re-partition.
Otherwise, there are quite many threads about how to restore lost imei on the i9000. Take some time browsing around.

I solved this
I did it by flashing stock firmware and I got my IMEI back.

Great!
Now backup your whole efs folder with the terminal emulator or ADB and save it on several places (different folders on internal and external SD as well as on your PC). It is explained how to do it in my thread.
BTW, on this forum it is kind of nice to click on "thanks" button leftmost beyond all helpful posts.

I know about the thanks button. Just because I'm a new member doesn't mean I haven't been around on this site for quiet a while.
But how do you backup the EFS folder?

I've already written you: it was described in my newest thread, I've posted it also here:
http://forum.xda-developers.com/showthread.php?p=45551390#post45551390
The same commands like in the terminal emulator can be done by the ADB as well.
You can easily find good threads here on XDA forum how to backup & restore IMEI

But for great tipps you should not forget to "klick" the thanks button ...it doesn`t hurt :fingers-crossed::good::laugh:

[Q] Your opinion please for a M/B transplant.

Hi, recently i managed to brick my Korean F340L G Flex so bad. I've tried almost everything software wise.
-The solution:
I'm planning to change the logic board from a Sprint LS995 model. I think it will work ok. Of course I'll have to some how get an unlock code in order to use it in Greece where I live.
I've seen in ebay some users providing for a small amount of money this code.
So, what do you think. Will it work as I'm thinking? Any comments, suggestions, guides welcome. Thanks
Here is a short story:
"Hello, to all, I'd like to share my experience and problem with my LG G Flex, as a last hope to find a solution to unbrick it.
I know that the talk here is about G2's, but I saw many users reviving their Flexes with OP's method.
So here is what I did in steps:
1)I rooted my Lg g flex F340L
2)New OTA, downloaded, but failed to install after reboot. The message was no OTAs for rooted devises
3)Tried to unroot, but with no success. Still no installation of OTA.
4)Found, and flashed the stock F340L rom , (had an EFS backup), from another user here(.tot file), with LGFlashTool.
5)SIM card was not recognized any more (Greece, Vodafone), so no calls. Did all the updates, but no SIM, still.
6)Hard reset, still no SIM.
7)Decided to flash stock F340K kdz rom, and install CWR. All good, SIM detected, OTA downloaded, but after reboot stuck at CWM nenu. Whatever I do just CWM.
8)No download mode, or usb support, just an LG FLEX unknown device. Got some drivers only to be seen as lenovo ADB device.
9)I found the test point on the motherboard and short circuit it. Got a qhsusb_bulk(qualcomm 9008) under COM ports, but not on a specific port.
10) No flash capability, and no partitions to try and flash the 10 or so, images. Ubundu, no luck with the partition detection either.
11)After many reboots and button long presses the CRW came back...again
Well as I can see, there is not so much support for the korean variants and I might have destroyed my phone. So, I need your advise in changing the motherboard. I found M/B's from AT&T and Sprint variants, to install to my F340L. I think it will work. After I will purchase an unlock code from lets say ebay to unlock it to all GSM networks ( I live in Greece).

What is CRW or CWR?
Are you referring to CWM? The recovery?
If you can boot into cwm your phone has a chance to be saved no need to change the mb.
By the way sprint doesnt give out unlock codes like att. There is an specific process to sim unlock sprints variant.

Yes sorry, CWM I was refering to. Well, since I have no other option at the moment. I'll try to find that specific process you've mentioned when I get the board(help or hint welcome)
As, for the M/B change, no system partitions are recognized in order to flash individual .images to unlock them.

If you can access CWM you dont need to flash the .img files for your phone. Instead you could flash a stock zip through adb sideload or flash twrp through sideload too. Twrp allows MTP use so someone using an F340K can help you with a stock backup and you can unbrick instead of changing board.

The only stock image I have is in .TOT file for the L variant. I also have stock .kdz file for the K variant. I can sideload to /sdcard/0/ directory only, if that helps. I'll try to find twrp.zip and try it. But the main problem is to find stock rom in .zip format.

I've managed to install twrp 2.8.0.0...

Ok, this will take time friend.
I will try to make you a flashable zip of stock F340L KK.
Maybe it will take me some 4 or 5 hrs.

How to back up my factory ROM?

Just got a new unit and would like to make a full backup of the factory ROM before proceeding to try out different ROMs. I did find an old thread from 2011 [HOW-TO]Create Custom ODIN Images for Backup/Restore but I'm not entirely sure if this is still accurate advice.
Also, it says that the device needs to be rooted in order to make the backups. My understanding is that if I root the system it will be detected by the system and OTA updating will then be disabled, which is not what I want. So my second question is: Is it really necessary to root and if so what is the best temporary method?

Small piece of advice my friend, be sure to include EFS in the backup to be on the safe side, also I suggest making a copy on a external SD or transferring to a PC

Why efs?

According to TWRP they say:
Some devices have “special partitions” like WiMAX, pds, efs, etc. These partitions almost never need to be included in a normal backup.

I already did one restore from my backup which had not included efs and it worked ok. What exactly is efs and why would we need it?

The EFS folder contains important information from the phone, like the IMEI for example, and if it gets erased by error it may affect your ability to successfully connect to a provider. Backups in TWRP will give you the option to backup important partitions one of those is the EFS folder, alternatively you may also use an application to make a backup (requires root) like EFS Manager(IMEI)-Note4 on the play store.

N910T3 please help me get EFS

Can someone with a T-Mobile Galaxy Note 4 N910T3 that has a TWRP backup INCLUDING the EFS please upload that and give me a link. I screwed up my EFS and if someone with the same phone could please make and upload their TWRP backup (just with EFS box checked very small and not your data) for me it would be greatly appreciated. I know I will have to go into it and edit my serial # from yours, but it should get me back working.
Thanks

Efs backup from another device will never work because it's related to your phone's specific hardware.
You did big mistake that you flash backup and efs from old phone to new one that completely screw up your efs partitions and drk ( device root key ).
Sorry but you should make always efs backup from twrp in microsd card before start messing with phone. Cuz flashing always risky job.
Trust me odin or twrp will not going to help you.
Dont waste your time You should go to repair center cuz they have tools like dongle box to fix efs and imei.
They will write new cert files and restore your efs but i dont think they can fix drk cuz i see many drk damage cases but didn't see any working method unless changing entire motherboard.

Kies doesn't work with Note 4, Samsung Switch freezes. Odin works fine, but that is not the point.
I need a N910T3 TWRP EFS nandroid backup file from someones phone to flash it. That is what I can not find.

[need help] no imei after flashing custom rom [xt1805]

Hi, everyone.
I appreciate if anyone can help me restore my IMEI. I can't connect to network after flashing a custom rom. I've already flashed different versions of official firmware via fastboot, twrp flashable stock ROM, and reflashed modem and erased modemst1 and modemst2 to no avail. I've exhausted every possible option without having to send this to a service center.
Thanks and best regards,
Geb

Thanks for your kind intention. I've tried that method before to no avail. I installed all necessary drivers, and followed the steps faithfully. i was able to extract the qcn file, explore the contents of the EFS partition, modify the qcn file and edit it, but the dead end I ran into was the phone itself is write-protected when I send the qcn file back. Can you please share with me your backup of TWRP EFS partition? It's the only thing that can possibly save my phone. Thanks.

By the way, my IMEI is still intact when you use "mfastboot getvar all" command and in the "Barcode" in the bootloader menu. It's just that the IMEI = 0 when I dial *06#. I know it is in there somewhere. Perhaps you can share with me your EFS and Persist partition backup in TWRP?

A guy in Moto G5 Plus (potter) forums tried that, his IMEI is still zero, but he got back his signal. I will just try and see if it will work. I'm not a criminal to use someone's IMEI, I just don't want to give up on my phone just yet. Can you IM me a link of your EFS backup, perhaps?

Using someone else's imei has great potential to cause great problems for you and the person who gives it to you. Never give away your imei or use an imei from another device.
