Hi all,
because I damaged bootloader on my device, so I tried to find solution for bootloader recovery.
And finally I detected jtag pinout on Asus P835.
See attached picture :
Jtag connector is located under trackball, so you have to remove trackball before connection.
I used donor bootloaders for recovery and device is working again .
If anyone is facing similar troubles with this device or has some new information please update this thread accordingly.
Hope this can helps to someone else.

I'm read this, but i'm don't look, what cable use for upload bootloader. The software called pnewbootloader.exe don't have any option, or other switch. (com port USB port, speed) With usb cable and with Serial Link cable have no communication.

its only serial mode when i connect usb cable windows says unrecognized device and before was ok even when was not powering on windows recognize device. Then i try to flash it again with jafwm and first part of rom was erased but nothing was writen to phone (writting error).

A hard reset may be the only sollution....
Hard reset isn't going to help if the phone won't boot !
So you wrote the SPL of a different phone to your TP2 ? That doesn't sound good
JTAG only

JTAG=Joint Test Action Group ????
jepp, but no one has figured out the pins yet
If someone does it, can it be used to connect the "dead phone" to PC to get it flashed???
Muahaha, yes. But trust me, that's NOT so easy as you think. This requires EXTREME skill.
Thanks, are you working on it then..?
Are you kidding me?! Too hard for me, despite the fact I'm studying Electronics X_x
You can do it as a case study, in your class...
yes my htc tp2 is dead only on led orange when connect usb
not enter in mode boot
no recongize drivers qualcom
I know that just is repair via jtag but I think and believe exist other solution
i will make cable serial for connect the htc via com direct for
format the internal memory and after reflash the spl and wm
someone has image
JTAG pins TP2???
Hi there
I have accidentally close the LG Flash Tool while the program is flashing my phone
And now, the phone stays in black screen and keeps in download mode
When i try to flash the phone using LG Flash Tool again with TOT/ universal DLL
It seems that the phone has lost PID, IMEI, Phone Model, SWversion information, therefore the flash will not run
I have googled for half day but can't find any answer, Pls HELP!!!
(pls forgive my english)

Your best bet would be to use LG software tool. You will get the rom at the factory setting and you will have to root the phone again (if you so desire). The tools and drivers can be downloaded from the link below. Once you install the tools on a PC, just plug in your phone with USB drive and follow the prompts. Here is the link for the tools:

Good luck!!
Nope no solution. Motherboard is corrupted. Use your warranty and get the phone RMA'd
Thanks for reply
The phone has been repaired by a professional
There is no any soldering required, and done by shorting two pins on the board, and flash with qhusb USB interface
Quiet simple way to repair
All imei/other info exists
After requesting repair at the official OnePlus Side, they told me to backup my phone(Stock OP 7T). When i connected it to my Windows PC it didnt appear in the Windows Explorer. After some scearching i could find it in the Device Manager under COM5 with the Name given in title. I am worried because when i googled Qualcom Diagnostics i saw that my device might be bricked or smth. But i didnt try to flash any new software or anything alike. i didnt charge my device for over a week so could theren be a connection with missing Power/Battery and this problem. Because my Screen is broken (Blackscreen) I cant see any info might given by the Phone itself. The only sign of functionalty is the detection by Windows.
Maybe someone has Tipps or a Solution for me

If you connect your phone to pc while its off and holding the volume down button it will boot into Qualcomm recovery mode which is what you are seeing. I suggest you find a way to switch it off and boot it up again
