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.
Hello
I bought a LG G3 a month ago.The model was D855 and running on stock kitkat.Later i updated my phone to Marshmallow using Lg flash tool 2014 but it showed some errors [no network,no wifi,no bluetooth] and the model number converted to D855V. Then searched and found my device with LS990 motherboard and D855 casing by getting help from this http://forum.xda-developers.com/lg-g3/help/d855-converted-to-d855v-t3121183/page4
As my device is LS990 i found solution to restore it using this method http://forum.xda-developers.com/spr...de-how-to-restore-sprint-lg-g3-ls990-t2852042 FAILED! I tried LS990ZV4 tot with LGUP8974.dll using flash tool.So i didn't have any solution to restore it without changing current build.prop to LS990 build.prop.And for that i need root access but i failed to root my stock Marshmallow .Then i was trying to downgrade my device using D855 firmwares where stock Lolilpop worked but no MTP connection.I decided to go for stock Kitkat so that i can root and change build.prop but it occurs bootloop when i flash with stock kitkat.I tried different version of D855 kitkat firmwares but the result is same NO SUCCESS! .And today i was trying to flash another version of Kitkat firmware which caused BRICKED my phone.Now download mode is not working.Only Fastboot mode.
There are some solution to fix Download mode.But i don't know which model to try for solution LS990 or D855 ?
How can i Unbrick and restore my phone to LS990?
TIA
i have lg g3 D851 mobile
is in dead condition because of flashing wrong file.
phone needs to replace motherboard or is there any other task to solve the dead boot problem after flash wrong flash file
i tried so many ways but no result..finally i decided to replace motherboard
My question is :angel:
does lg g3 D855 motherboard is compatible in lg g3 d851 mobile????
i don't believe that replacing mobo is the only solution... first try a few tutorials to unbrick D851, then research about test point or how to force the phone to flash.
also maybe a professional can flash it via SPI flasher or something
Suggest me
Does lg g3 851 mobile body is replaceable by lg g3 d855 motherboard(logic board)
Yep ??
I changed my imei with QPTS Tool
Now my mobile imei woking fine and it gets network too
But one more problem is
When i enable 3g data connention then the symbol on status bar showing 4g symbol also same while using in 2g mode
How to solve this.........
Short long story
Purchased in USA LG G3 d855. It arrived with Lollipop 5.0.1
The phone was recognized as model 855m IMEI also detected as 855
Due to huge battery drain I decided to root, upgrade to 5.1.1
When flashed TWRP for 855 it brick the phone.
I have opened it and noticed that board is 851 model.
Recovered from brick using BoardDiag with 851 TOT.
So now the phone is T-Mobile, not detects LTE ( Im afraid 2G as well frequency).
IS it a way to restore it to origin situation or to more update D855 ROM?
