H810 AT&T Bricked - G4 Q&A, Help & Troubleshooting

Hello, so I think I might have seriously messed up my G4.
I started by trying to root using an H810 10G kdz, that led to my phone being soft bricked with access to the Download mode or a security lockout.
Then I realized that there was no official H810 kdz to return my phone back to stock, and found that using an H810PR kdz would work.
I tried the LG Flash Tool 2014 to to put the H810PR10a_02 kdz on the phone, but the program crashed and now I am getting no response from the phone.
So basically what are my options now? Is there anything I can do, or will I have to send it back (also if anyone has info on the affects on the warranty, that would be helpful) ?
Thanks

I have qhsusb_bulk with my H810... are you resolve a problem?

Flashing Original Carrier Firmware on LG G3

I purchased a used Verizon LG G3 from someone online. It has Verizon all over the device; however, whenever I turned it on, US Cellular popped up on the screen. The guy told me all I had to do was call Verizon and they would activate the phone.
I contacted Verizon, and they said there was nothing they could do. I talked to a friend of mine and he said that it looked like they flashed the phone with a US Cellular firmware as the device is a VS985 but it is showing up as US990 on the firmware. I have tried flashing it back to a stock firmware of Verizon using the FlashLG Tool and stock *.tot file to which it fails and just says device model is different.
My question is, is there anything I can do to fix this or is this phone basically a paper weight?
I'm kind of new to this, so any help would be appreciated.
Thank you
Try flashing 24b using the KDZ method...

[Q] Motherboard Changed From E988 to a E980 at LG Service Centre?

Hi guys in urgent need of your opinions. When I went to an LG service centre after my phone died they replaced my mobo (E988 Singapore) with an E980 one. Soon after before I managed to root and unlock its bootloader I checked through the device details and the funny thing is that I realised it doesn't tally with any AT&T or non-AT&T E980 models as the model number was just listed as E980 and if I remember correctly the version number for the firmware listed it as an EU device?
I went forward with modding the phone and everything went well until recently when I tried to switch recoveries from CWM to TWRP. Unfortunately due to the confusion regarding my hardware (whether it was really an E980 or E988) I mucked up the process and am left with soft bricked device. Any ideas how to fix this? I don't know which KDZ file to flash for my situation. Please help me solve this as I really need to use the device urgently.
I think you'd be fine just treating it as an e980 and flashing back to stock
So I should just use any of the E980 kdz? I don't wanna risk hard bricking the device but I'll try it when I get the chance.

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.

have to leave my dedicated carrier forum to get answers for KDZ and or tot method

Multiple threads little to no replies besides sensless info that ive already tried
CAN TOT METHOD WORK ON TMOBILES VARIANT G4 AND IF SO WHERES THE LINK FOR THE TOT FILE NOT KDZ!
Tmobile g4 forum is helpless after days and 100s views
this is my last hope. I Have a tmobile lg g4 model. I hapened to relock the bootloader while i was still on a rom and rooted with twrp, but i do have download mode and only download mode .I dont have a bootable o.s
Ive tried and tried and tried to get lg UP Tool which is a joke its not really a true unbrick tool cause if you bricked yourself on a rom and not the stock firmware its useless .All you get is device model unknown. This is supposedly cause custom roms are edited. Lg bridge does not work as a brick tool either it just states wether your firmware is up to date . The only hope was lg flash tool 2014 but that im told and seems to be outdated not compatible with any g4 on android 6.0.... Im at a loss here i can get into dload mode thats it the phone charges in download mode also and it also is recognized by pc meaning drivers are installed because lg mobile support tool sees my device and says its up to date.
s
Some members have been in my same scenario relocked bootloader with a rom and twrp with nothing but download mode and swear they fixed it with lg bridge tool using the update recovery error link within the tool.
Can anyone confirm if im screwed or if i am doing something wrong this is day 5 now im ready to toss the g4 in the trash for the sake of my sanity.
