D851 motherboard problem - T-Mobile LG G3

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.........

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.

D855 motherboard inside D851

Is it alright to use D855 motherboard on D851? I've sent my phone for warranty after I lost my imei and they say they need to change the motherboard and when I get it the software use D855. So does this mean I can flash D855 rom on my G3?

Lg G3 stuck on LG logo after Android 6. Cant use FlashTool

Hi,
So someone gave me a LG G3 which he updated to "D85530C_00_0211.kdz". After that the phone stuck in the LG logo and it rarely loads the phone but it freezes. I can barely unlock the phone sometimes but usually it doesn't recognise the touch.
Neither the PC is recognising the phone.
I tried to use LGFlashTool with TOT file but after "READY" when I unplug and plug again it says "Download Fail".
I also tried with the older LGFlashTool using the KDZ but still didn't work. It only worked with the KDZ above, which is the same software and again it is freezing.
LGUP isn't working too.
Any help/suggestions?
P.S.
Maybe I'm using wrong TOT/KDZ?
-The version he updated and also I was able to install is D855
-Under the battery writes "Made in Korea" which may be a Korean phone but Korea doesn't have D855
-I searched on imei.info the IMEI number and it says Carrier Poland.
-I tried using Poland KDZ, Hong-Kong TOT (because they have d855) and Europe TOT(which also has d855)
-The phone is 16GB
I do believe that your board is not of d855. It happened to me a month ago. When I opened the phone.I saw d850 written on my board.so that might be the problem.

It says D855 behind the phone. Also all parts do write D855 and a number near by. So it must be a D855.

Lg g4 h815 .No service. Need help pls
I am from india. I recieved an international version lg g4 h815. Software version H81510h. I upgraded to H81520L MM using LGUP. After that I'm not getting network. The mobile network option in settings is inaccessible and not highlighted. The phone works perfectly appart from that. I tried searching the issue. I guess it has something to do with the change in modem after update.
Its a case of very low signal reception. I can get 50% signal where it used to be 100. And no network where i used to get 50% network. Anyone solved this issue?
Check your imei i suspect that your modemst is corrupted..
