Lost IMEI need help

Dear Friend,
anyone of you have G-PRO especially those with non-international version should backup your IMEI before trying to upload any new ROM. To back up, please download the tool below (I took it from M_Tool of someone I don't remember) and run it from a CMD Administrator windowl; you should also have your phone connected with debug mode, rooted phone and adb.exe shall be in PATH.
I bricked up my phone with losing the IMEI, i could restore partly now but could not connect to 3G network (only GSM). The reason was that my back up lacking of some files. So anyone have G-PRO F240L or a 988 please be so kind to give me a version of your backup. I need that to make my phone back to a smartphone.
Regards,
Quang

Have you tried taking your phone to a service shop? I believe that would be your best shot. They might restore it in a matter of minutes...
You might have better luck choosing an independent store rather than a licensed one.

some times its a imei issue. in my case it was sim tray issue. i had to change the sim tray from service center only.
have you taken backup before flashing new rom?
if yes, then restore the EFS folder from CWM or TWRP backup

[SOLVED] This phone is permanently locked and cannot be unlocked

As the title says my phone is hard sim locked.. I am not hopeful but i will try my luck with asking here..
Is there anyone faced this problem and solved it ?
I dial 2945 #*855# and all of the options are not possible to enter any IMEI. all of the says "This phone is permanently locked and cannot be unlocked"
I tried putting a sim card different from my provider but it doesn't ask any unlock code to enter and 2945 #*855# is the same..
It happened after flashing a custom rom and it f**** my phone. Also i can't afford to any other phone, i am a student
So I would be glad if anyone can help me to resolve my issue. I believe I will never forget him/her.

Losing the IMEI code is the worst thing that may happen to a modder.
Try to connect device to PC and follow this procedure to put it in stock conditions.
However I'm much pessimistic about the recovering of IMEI code, try and hope to solve the issue.

Error Code: Secure boot 1002 - What should I do? Please help

Dear XDA community
I recently bought a LG G4 from an online retailer. According to their website they said it was a UK model, which according to the back of the phone beneath the battery it is: LGH815. But then after booting the phone the ROM being used was: LGH815T. Then I typed in the IMEI number and found out it was a: Verizon US model??
Basically I am having trouble identifying my model. The phone apparently came unlocked and rooted, but the person who sent it must have done something wrong because when I flashed a TWRP recovery image to the phone it comes up saying: secure boot error code: 1002.
The good thing is, is that I can boot into the device and still operate it as per usual. But what I want to do is bring the recovery back to normal. I was searching around and apparently there are some KDZ files that can be used just to flash the recovery? Is this correct? If so could you assist me in what I have to do to fix my issue which is: secure boot error 1002.
I would really appreciate any help regarding the matter. :crying:
Tried posting photos, but forum would not let me, all they showed was the model numbers.

Use LGUP-NEW ( https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803 ) to install/flash ... the appropriate stock KDZ for your specific model once you ascertain it (LGUP - NEW may recognize your model and you can use that info to find the right KDZ). You will have to re-root the phone if you still wish to have root.
If you do root, suggest you might want to check out steadfasterX's [LOCKED][G4][TWRP][UNOFFICIAL] TWRP-in-FIsH for all locked G4 devices at: https://forum.xda-developers.com/g4/development/locked-twrpinfish-locked-g4-devices-t3573048
It has been tested on locked devices AND unlocked devices. Version 3 Beta 4 and 5 seem very stable and the links are available in the later posts on the site. It works like a charm and has been tested on a quite a number of devices now.
Addendum: I'm wondering if the online retailer may have meant it was carrier unlocked (i.e., so you could use other service provider's sim cards), not bootloader unlocked? That could account for the secure boot error getting TWRP to load.

open phone . take out mother board .. and read plaque model. if sprint flash sprint KDZ and LGUP. if H815 then do that .. thats the only way to be sure.

U have a refurbished model.Go to nearest mobile repair shop & take out your motherboard to see what model no is written on this.Then flash a rom accoringly. Don't flash any other rom just by assuming else you will brick your device.

Yes my phone is refurbished...
But how to flash the rom?
If I found it to be a sprint version and flash a sprint rom ...it will be locked?I am using phone in India...

Any chance to root the phone and install twrp?
Then flash a custom rom?
Please help...

Most probably it will be locked cause most higher Android versions LG has blocked rooting or unlocking..But you can always browse few threads.
Mine is also a refurbished model with F500L motherboard,LS911 body & had H815 global rom installed out of the box.I am currently on F500L Nougat locked & unrooted..I have tried almost every method.It failed to root & even to enter fast boot.
If you get your proper model no on motherboard then just flash the rom with ToT flasher in download mode with respective DLL.

Your network is locked?
You cant unlock it?
Can we degrade our Os to lollipop to get root?

Even I cant turn on the Enable OEM unlock under the developer mode...
Any more advices?

Please help.....

I have tried almost all h815 ans ls991 roms with all flashing methods but still unable to successfully flash my device...lg tot flash tool always show dl error after 4 to 6 percent of flashing...
Please help

Any idea's?

Pick the phone, and send it to the place where you bought it. If you have warranty the repair is free, if not, then you must pay sadly.

Still no solution, I even cannot enable OEM unlock under developer options...
It automatically disables it...
Please help

Just experienced this issue after changing sim card... Call and Camera stopped working over and over again.
How I solved it: Go to the specific app that is causing you trouble, and clear cache/files (too bad I only found this after 3 factory resets).

Maybe it will help ... LG G4 CAM

Your device failed verification message after every boot

I got a z2 play today and right after the first start it turned off and this message started appearing (it's the same than on my g4 plus that has unlocked bootloader but the Z obviously doesn't
I'm from brazil
Do I need to get my phone replaced?
or is there any fix I can do myself?

Obviously this is reason for concern and but let me put a positive spin on this ...
Let's assume you got a new device (not refurbished / used), and the device is working just fine. This could be actually good news. Because that message usually shows up after unlocking the bootloader. Unfortunately unlocking normally cancels your warranty. You can only unlock the phone by requesting a special unlock code from Motorola. This way Motorola can easily check whether you unlocked your phone and decline (warranty) service. But since you have never done that, you might have an bootloader unlocked phone with warranty.
> or is there any fix I can do myself?
You could research "fastboot oem lock" but if the above is true, there will not be any advantage whatsoever to do that.

I faced the same issue
after normal use ,no root or unlock bootloader
my phone crashing frequently
and after reboot I Received that error
and I can't update anything via OTA
I started a topic at Lenovo Forum
an Expert suggest me to return it to vendor
so I return it the vendor yesterday
now I hope for a full refund.
Here is a link to Lenovo forum

I fixed it myself by installing the stock room via abd fastboot, if anyone is facing this problem, my phone is working normal and the message is gone so I bet I got a fix.
