lg g3 soft bricked/ problem with models

hello everyone
i don't know about android that much
when i first bought my lg g3 LS990 "sprint device" i had some issues with the 3G/LTE since i live in middle east and the only way to access 3g signals is through CDMA??!
anyway... i went to a repair man and told him about my problem he rooted my phone, flashed a custom recovery "TWRP", then flashed a custom rom
when everything was done he managed to fix the 3g signals some how but the phone still wasn't able to get 4g signals
the weird thing is that when i checked the system info the mobile's model was changed from LS990 to D855
i didn't pay much attention to that back then but in the meanwhile i did some stuff and i had to flash a custom rom so while doing that my phone soft bricked
now i'm trying to flash stock rom again the problem is when i tried to flash LS990 stock rom i had an error message that says "device model is different"
and when i try to flash D855 rom it proceeds to 6% then an error message occurs says "partition change fac... 00000064" can't see the whole error message cause flash tool is not re-sizable
so now im not able to flash D855 model's rom or ls990 one
what should i do please i need help if anybody knows
would try anything thanks in advance

Cannot unlock bootloader on a repaired H815

My bootloader unlocked H815 suddenly froze (hard bricked) with no response to anything other than the boot screen.
Sent it for repair. They replaced the CPU and RAM. The repaired H815 came back locked with 10C.
The IMEI stayed the same, but the device ID was changed (fastboot...devic-id).
When trying to obtain a new UNLOCK.BIN file on the LG developers site, I get the message that my device ID does not match.
I managed to root the H815, but I cannot install a recovery (TWRP). This prevents me from installing any ZIP file since I have no access to recovery (XPOSED, V4android, etc.).
Please advice
Thanks
Anyone?
U should email lg developer for help.. I saw a lot of people facing this problem also
Sent my IMEI and new Device ID to LG (via LGE Developer site)
waiting for the new key file
Waiting for the Sקמא צט
I just sent a mail to developer (at) lge.com with the same problem. The IMEI stayed the same, but the Device-ID changed when they replaced the motherboard. I had unlocked my g4 before it went in repairs. Actually the combination Genesys MM with xposed 79, G4 tweaksbox, the lack of recovery installed and USB debugging disabled is what hard bricked my phone in the first place. Something made LGUP unable to find the model of the phone.
I will update this post with any response I get from the email.
UPDATE:
It worked. They asked me to send a photo of the back of my phone (with IMEI number). After that they said I could try again and that the site should now give me the unlock.bin. It did.
Thanks LG!

LGD855 Changed to LS990 after flashing wrong rom.and wont go back

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.

No signal, wrong country version

Hi,
I have a problem with my LG G3. The phone shows the well known message "Current version is not available for user. Can't find matched cust for NT-code mcc/mnc[], subset[]". If I insert SIM, the phone won't connect to any network.
This is how it happened:
I bought the phone form Aliexpress as refurbished. It came with Android 4.4. It could not find any update for my ROM. So I decided to root it and install CM13. But during the rooting process the phone got hard bricked. I had to follow the guide with shorting pins and Qualcomm driver to restore the phone. Unfortunately I didn't have the original ROM. So I flashed files from LGD855AT-00-V10e-EUR TOT. Then I was at least able to get to download mode and flashed a European Lollipop ROM with LGUP.
Since then I'm getting this error message no matter which ROM I tried. According to IMEI the phone location code is A6GBTN. So I even tried to install a UK ROM without any success.
I think the fault might be caused by the fact that during unbricking I flashed also do misc.img partition. And now the data in it don't match with my phone. Is it possible? What should I try?
Thank you.

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.

Thanks for your reply...
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
