You need a QFIL dump and rawprogram files. I am searching for them as well, but currently I can only find the ones for the Sprint variant.

I bricked my Wellcom A88 (A71 variant) and the power button won't even turn on the phone. I know on some devices there is a way to still talk to the flashing chip by pressing certain key(s) while plugging in the USB cable to the computer. Is there a way to do this with this device and does someone have the special flashing tools that would be needed to revivie it? Right now my phone is completely dead.
I found on google that you can boot in emergency download mode to flash a stock ROM
Do this by pressing these buttons: (volume up + red button + power)
I hope that works

I cannot do that because the power key doesn't turn on the phone. The only thing that happens is the red light comes on when the charger is connected. Other than that the phone is completely dead. I cannot boot into any mode because it won't turn on at all. I know on some devices there are ways to either jumper something to reload an emergency bootrom for flashing, or a way to connect directly to the flashing chip for emergency flashing. On this device I cannot find a way to get into a flashing mode without the power button and it at least going through the bootloader, which jumps to the mode based on the keys pressed. Since the power key isn't doing anything I cannot get into any mode.
Thanks for your suggestion. If I could do that I would have done that already. i appreciate you trying to help though.
I will try taking it in for service and see if they will fix it or replace the motherboard. If they refuse I know where the location of the JTAG points and I have a graphic showing which one is what, but I have never flashed JTAG and don't have a cable or software for flashing. It would also require disassembling the phone to expose the JTAG points. I hope that is not a road I have to go down, but if the service center won't help me that will be my only option. If anyone is interested here is a photo showing the JTAG points for the the variants of the Foxcon A668, which are Wellcom A88, Apanda A60, Orange Boston, Cincinnati Bell Blaze, Gigabyte Gsmart G1305, Motorola XT502, Vibo A688, Chinavision Excalibur, Muchtel A1, Commtiva Z71 and Nexian Journey Lounge, CSL Spice MI300 and many others. This phone has to be one of the most successful rebranded devices ever.

You still haven't explained anything. What do you mean "dead boot?" What exact files do you need. If the phone won't turn on at all there is nothing you can do.

Hi everyone.
First sorry my poor english.
Yesterday I received a phone (LG L4 II E467F Dual SIM) from a customer, the unit was but connecting the loading stopped with the LG logo and stand on this screen. I tried to upgrade the PC Suite, the cell was placed in download mode and the update is performed by the software, download and recording was carried out on the device during the recording process progress was up to 94% with the power on, when he got 95% the device was turned off automatically (A device's battery was at about 70% during the process), then the process has reached 100% normally without error messages.
After this the phone turned a brick, does not care, does not vibrate, does not go into download mode, finally does nothing. But noticed that it was shown in Windows Device list without driver. I used a software to install drivers and the device driver has been installed and he was recognized as "USB Port MTK (COM5)."
I watched a few topics about it, but could not properly understand the procedure and I was afraid to end any device recovery chance.

Does anyone know how I can recover the bootloader of the device?
The bootloader is my biggest concern, because if the device start and stop again with LG logo can at least return the device to the customer.

The phone stucked into LG logo. Tried many times to flash with LG flash tool. But it says download fail, device model is different.Check ur phone or dll. Tried generic dll but not working. Any help will be much appreciated. Thanks.
Hi XDA friends.
Am from india. am using LG G3 D858HK model 32gb dual LTE version.
My mobile as bricked last 2 months back Model as LG G3 D858HK Hong Kong version 32GB varient. Actually i mistakenly installed another not compatible Rom(Android operating system) like Cynongenmod 12.1 on this device. so my mobile not working like below symptoms are behaving.
1. display not coming
2. only without battery as showing like not charging no battery inserted display
3. led light as blinking when its i press back power button
4. when i press back power button its showing like 0% battery no charge(when i insert battery)
5. its not displaying download mode( i pressed special keys like top volume +button and power button and inserting USB for installing OS
So its possible to solve this bricked mobile to unbrick (LG G3 D858HK)
above issues are am getting. but i tried to repair my self. when i insert USB it showing in device manager LG Android usb device. not showing qualcomm hsb like. i properly installed QDLoader HS-USB Driver_64bit_Setup. but it below link as per your mentioned my device hardware as been different. so how can i find it GND and EMMC pins ( for short in using copper wire ) in this mobile LG G3 D858hk. actually am already checked in that mother board but i didn't find pins and GND. compare to sprint model or else D855 model as different between my device.
Please friends help me out on this
Hard-bricked LG G3 D858HK
Will you please, please help me too!
It seems I've hard-bricked my LG G3 D858HK Dual Sim 4G LTE 32GB too. It wasn't updating the firmware (only found out 3 weeks after warranty expired). So, successfully flashed the ROM to Marshmellow 6.0, then tried to root it with (mistakenly) wrong firmware - lollipop app/tool.
Problems: black screen, won't boot (red & blue light flashing), won't go into download mode, computer not recognising phone/USB is plugged into - even with right drivers installed.
My LG v10 stuck on LG Logo, but when I attach an USB cable with computer it further goes to att logo and after 3 or 4 spins, it again stuck on att logo. I can get into download mod but not recovery or safe mod. I tried to flash my phone with LGUP but it shoes unknown model. tried with upper cut and common folder options but no luck. LG flash toll 2014 does not detect my phone and application stop responding when I try to read phone information. tried on different computers, different USB cables and different windows but the result is same. Once I had a LG f350 and faced the same problem. Only LG Flash tool 1.8 worked for my LG F350. I am hope full it may work for my LG H900 but I can't find TOT+dll file for LG H900 nowhere. Any one can help please.
I was on 5.1.1. rooted, Super SU and busy box installed when I tried to factory reset my phone and got into this trouble.
More Problems
I got a LG Firmware Extractor from a post on XDA. Extracted the KDZ file and got a .dz and .dll file. extractor also showing another file (something like .dllyib i think) but I ignored that and extracted what I needed. After that I flashed my phone with lg flash tool 1.8.. but flash tool kept on installing system file after 100% but my phone was stuck on 99%. After 117 % flash tool showed "waiting for connection" and then failed. I tried to reflash and got the same result. Now after showing LG screen, my phone got stuck on a black screen showing some bars going up and text "MiniOS" and stuck on this screen. I searched for the solution and some one told me to disconnect phone when flashing reached at 99% and then reattach it after changing the port. I did that but what I got was worse than before. :crying: Now I can get into recovery screen but after applying factory reset, phone goes off and restart again without doing any thing. My phone is stuck on boot loop at LG Logo. it keep booting when i connect to a charger or my computer . I cant get into download mod now. when I try to get into download mod, the screen with some dots appear and then phone restart again without going into download mod. when I connect my phone to PC it only do boot looping and nothing appear on my computer. My phone does not appear in device manager. Is there anything I can do now????????

Failed several times and gave up with LG UP. So i took my phone to a mobile service center who is good at software flashing. i gave him nougat kdz F600S30D. He converted kdz to dz format and flashed with Octoplus box. my mobile was on 5.1.1 android and directly flashed Nougat. Booted flawlessly and no network problems as well Everything is working just awesome. attached my video of Nougat Overview
