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

prejudice and first excuse my bad english (google translate) and thanks for the opportunity given to solve problems unknown to us as in my case.
then I state that I understand a little but this is really strange, yesterday I got the bright idea to bring back to the data of the cell factory in question having the TWRP 2.6.0 for lg optimus g pro e986 doing so went in contrast perhaps with the recovery changed by always reboots and always going to end up in recovery ...
after which I started lg flash tool I downloaded the firmware e98620a Italian one I did recover after having finished I found a phone that does not read most of the sim, I have already tried to put other sim cards but nothing I have also tried my card sim in other phones and works perfettamete, now I do not know what to do ....
if you can be of assistance I typed in the dialer 2945 # * 896 # so entering the sim unlock process and any menu press I wrote out this phone is permanetly locked and can not be unlocked.
Now I do not know what to do I ask your help please help
thanks in advance to all
Hello Everyone I have a problem with my LG G3 which I have bought it recently was working nice but it had KitKat so I wanted to upgrade to lollipop but didn't know that LG G3 had different variant.
I've downloaded a wrong flash (LS990 sprint) and flashed it. so I lost the network and I noticed that the imei has changed. and I don't have the original IMEI of the phone ( the sticker on the back of phone is for D855 16GB not for D855 32GB).so I think its not the original IMEI.
After bricking the phone I've opened it and noticed that it was D855 written on the motherboard.
when trying to flash the original D855 rom it doesn't work (flashed it using the crossDLL method and using the Hex Method By changing D855 to LS990 to make the flash tool think Its LS990) the flash pass on both methods but i'm stuck on LG logo.
send it to some repairing services here in my country but they didn't fix it they thought its sprint so they flashed PrimeGSM but still no network.
I think I should change the IMEI before flashing D855 or something.
please Help me I've looked all over the NET but find no solution to this problem.
If you need more informations ask me. Help me as soon as possible this is the only phone that I have.
Did you ever figure out how to fix this? I have a ls990 which was flashed with PrimeGSM and is now detected as a d855... I have been trying to get this working for the last two days with no luck

Hello
What is the problem that you are facing ?
Is it a network problem or what ?
Primegsm is ported from d855 so i think it will show D855 on any lg g3 that does'nt mean that your phone detected as d855.
Make sure your phone is ls990 or another variant
And which country and carrier ? So i can help you.
I basically have a soft bricked phone - no OS as all. I am in New Zealand running on the Vodafone network.
I was using PrimeGSM and it was working fine but decided to go back to the stock ZV8, when running through LG Flash Tool I noticed Download mode was showing the model as a D855 and would not accept the LS990 DLL - I then made the mistake of using the generic DLL with a D855 image which started a boot loop - then made more mistakes and ended up with no OS and stuck at the LG logo.
At this stage I am able to get to fastboot and use fastboot boot to get into TWRP but cannot do much from there, I also have to use the D855 TWRP image as the LS990 fails with a device tree issue. fastboot will not erase any partitions or flash any images manually. Using terminal in TWRP I am able to browse the partition though but cannot mount the SD card or use adb to push or pull (fails with error closed)
I stuffed up quite a few times along the way but sure I can recover from it since I still have quite a bit of access to the device...
I managed to get my phone going again by following a guide I found in the forum, I am pretty sure it would solve the ops issue as well.
Really quick and easy, I just bridged the points with a needle and copper cable.
Lg g4 h818n isn't getting rooted by any method......help plzzzz.....i have lost all data of internal memory and want to recover it and rooting the phone is essential for it
Same issue but me I backed up my files on PC ??
I think first we should downgrade to 5.1.1 by flashing kdz via lg flash tool and then root the phone
Hi!
I have this G7 with the model LM-G710V with an unlocked bootloader and managed to successfully flash Phh-Treble by following this thread:
https://forum.xda-developers.com/lg-g7-thinq/development/rom-phh-aosp-8-1-t3808649 :victory:
but then i would like to convert back to stock but unfortunately there are no available KDZ for G710V in the interweb.
would it be possible to convert G710V to G710EM ,or to a similar effect, by flashing 10b Vendor img and boot img then the kdz found in this thread:
https://forum.xda-developers.com/lg-g7-thinq/development/dump-g7-stock-vendor-t3840834 ?
or would this just leave me with a dead bricked phone?
additional notes:
bought this phone as a secondhand from someone in facebook with the bootloader unlocked and with, as the seller stated, "G7+" rom with issues.
no backup was made before
Thank you for anyone willing to answer! :good::fingers-crossed:

Hello @xElouise, according to the LG Open Source Code Distribution website (here), the G710V is equivalent to:
G710VM
G710AWM
G710AWMH
G710VMP
G710VMX
KDZs from any of the models above should work fine, just note that they may come with carrier bloatware. Reflashing the stock firmware is the same as any other G7 version (here, up to the first half step 5).
Does your phone have an IMEI code and working telephony? Because from the info I have gathered on the internet, looks like the G710V is a retail demo unit without either baseband or IMEI.
Hey there! Thanks for the reply!
Unfortunately since after flashing Phh-Treble LGUP does not recognize the phone anymore (Shows up as Unknown)(maybe because i flashed the vendor img(?) idk.)
Anyway, since back then before flashing Phh-Treble i was already trying to flash KDZs Thru LGUP, but unfortunately LGUP throws me error saying it does not support cross flashing.
I have tested the following before:
G710VM - LGUP Error cant cross flash G710V to G710VM
G710AWM - LGUP Error cant cross flash G710V to G710
G710VMX - LGUP Error cant cross flash G710V to G710
This unit IMEI & Baseband says unknown. This also has the white sticker at the back with some of it's details like unit model, FCC Id, etc.

Try hooking it up to LG bridge. It will automatically recognize the phone in download mode and it will update it to the latest stock.

LG Bridge fails to recognize the phone on download mode.
It says " Notice: Can not connect. disconnect the USB cable from your computer and reconnect" done this multiple times, even swapped usb cables with other phone
edit: So i was able to make LGUP recognize the device again but still same problem with cross flashing <see pic for reference>

You can contact the guy that sold the phone to you and see if he has a dump. Otherwise I can pack the system and the vendor but I'm not 100% sure if it will work
Hi, is your unit the demo unit one, without phone function and with retail mode app? Did you encounter any issues with the flashed ROM so you're changing again? I managed to land one of those demo units but there's too much restriction for usage so I was thinking of flashing another ROM but I'm a complete noob with regards to that.
Thanks.

@LameMonster82 , The seller said that he bought it off someone when it has boot loop issues and have his buddy fix it for him & he does not have any backup (guess that makes me a third hand(?) not really affected by it since i got the unit for a dirt cheap price around <$100 and it's quite a smooth unit too).
If you could, in your spare time of course, make the pack that would be really much appreciated! Thank you very much!
@ceezae , This may be a demo unit since i got it without any sim functions and a blank IMEI. I don't know about retail mode, though there was an widget applet before which showcases LG G7's features. I already bought the unit with it's boot loader already unlocked so I have no idea how a G710V got unlocked. When i bought the unit it does not have any audio at all either thru the headphone or speaker that's why i flashed a custom rom.
Anyway , since I flashed Phh-Treble 8.1 the phone's working smoothly aside from the aforementioned bugs in this thread
I am going back to stock since i can not utilize the quad DAC feature in custom rom and I could not get Gcam to work (it either crash or extremely Laggy)
I would also like to mention that:
I can not seem to boot to recovery via (Vol down + Power button) it always say that "Factory Reset is Disabled by Kill Switch" even though OEM Unlock is ticked in the developer settings as well as unsynced Google Account.
And my internal storage is showing that I only have 16 GB of internal (would be easy to fix with TWRP but again no luck with custom recovery)

Hi there!
I am terribly sorry but my device is kinda a bit soft bricked(?) at the moment.
I was trying to flash the Stock Korean PIE KDZ and was successful but it had problems like WIFI can not be turned on and Random Reboots.
I think I also have lost access to Fastboot since the phone only Reboots itself normally.
My dumb self did not make a backup so I am a bit screwed at the moment.
Someone with an intact phone (which hasn't been flashed) will have to pack up their partitions and post it here. The G710V seems to be technically similar to the G710N but can't actually be flashed to a G710N (you can force this through using LGUP but it results in a phone that crashes all the time due to some issue with the wifi driver).

Hey, I tried backing up these via adb shell myself on my G10V but... "permission denied". Great. Probably because the demo units force a Retail Mode device administrator that you can't remove at all. Can't even access the page itself in Settings ("you are not authorized..." blah blah). It's a shame, because I was really looking forward to helping OP.
have you succeeded I have the same problem as you
