Sent from my LG-P760 using xda app-developers app

http://forum.xda-developers.com/showthread.php?t=2119090
So i got it to fastboot and then I flashed CWM with it to my Phone after that i flashed a custom rom via cwm --> Working
Now theres only one question remaining. How can i get a stock rom to the phone if this LG tool dont wirk is there a version for cwm and p760 out ?
I decided to downgrade from Android 7.0/Nougat back to Marshmallow, so I flashed the H850 .kdz file using LG UP to downgrade. Unfortunately it failed and now my phone only boots to download mode.
I have tried to boot normally and into recovery mode, but I am taken into download mode each time. Any help?
Edit: Fixed by plugging into LG Bridge. Bridge detected that it was running Marshmallow and updated it to Nougat, correctly restoring the software.
to downgrade follow

To begin with, I was trying to unlock Lg sp200 tribute dynasty phone , I was told that flashing lg k8 plus x210mula firmware will do it. Everything went well during flashing process using chip erase command on lg up software until it didn't.
The phone stuck in lg k8 plus logo, at first I went to download mode but then I tride hard reset way by using recovery method but everything went bad after that. I had been stuck at black screen since then with a message saying [LGE] [Image Recovery] op_image : 0 API Support : 3 and no ability to go back to download mode .
When plugged in, the phone was recognized by the computer for a few seconds beep and then disconnected after the message appears.
I tried lg up, lg flash tool and even plugging without battery using volume up method to get into download mode but no luck.
Now I need a powerful tool to get back to download mode to flash new firmware that I got recently.

Got a queation. Have you plugged your phone into a pc mac or linux machine to see if it registers. It being a qcom device it might show up as hsusb 9008 or qdl mode. If so you might be in the same boat as me. If it is check out QPST or QDL on linux and do some research. Im going to try to use qdl to revive my fortune2.
Worthy to note before attempting any kind of drastic procedure like exchange of firmware do extra research and make sure device hardware is compatible with the firmware you are trying to flash.
Some phones like the LG LMX210 variants called CV1 are pretty much interchangeable running the same hardwares. But there are a couple like my ulma that run mtk. Flashing mtk with qcom or vice-versa cause really bad. Thats not what i did i was just tired and wasnt paying attention to my procedure list and well you know it happens.
Hi,
I tried to upgrade my LG V30+ US998 to android Pie via TWRP but after the upgrade and system reboot the device got stuck in LG logo.
The download mode isn't working (device not being detected).
LGUP shows the device as "unknown" and adb is not detecting the device either.
I can't boot into TWRP anymore and flashing via LG flash tool 2014 fails (asks for server connection!).
I installed all the tools and LG mobile drivers on another computer and had no luck!
Do I have any chance of recovering my phone?

Why can't you boot to TWRP?
Use the hardware button dance, if you must.
__
Are you using the latest Dev Patched LGUP from the Pie KDZ threads? Uninstall any prior version and read the instructions carefully.

Your phone is not bricked. No one ever bricked their phone trying to update to Pie. Being stuck on logo is not bricked.
Tons of people get stuck on logo. So what? Then they re-flash 20h or whatever.

Reinstall LG Mobile drivers again.
Uninstall Dev Patched LGUP completely. Delete the folder from Programs/LG Electronics to make sure.
Re-install the Pie Dev Patched LGUP. Use the SetDev.bat in right click Administrator mode.
Then REBOOT the PC. You've installed two major PC components and Windows needs to process that.
Go into Download mode MANUALLY before opening LGUP. ONLY open LGUP from the desktop shortcut, not the folder icon.

I tried every possible combination of the available apps.
Phone in download mode not recognized by the computer (tried on two computers).
If I connect the phone into the computer and open the LGUP it shows as "Unknown"
For some reason TWRP got wiped out after flashing Pie rom and I cannot boot into twrp to flash the old Ore rom.
I finally managed to fix my phone.
Below are the steps:
1- boot the phone im fastboot (connect to tbe computer via USB cable and press and hold both power and volume down until phone reboots then quickly release the power button and hold the volume down until the fastboot menu appears)
2- copy the twrp image into adb folder and rename to twrp.img
3- download and copy a working rom (in zip format) and paste into micro sd card and insert into phone
4- open the command prompt as administrator and navigate to adb folder then type the following commands in sequence
Adb devices
fastboot devices
fastboot flash recovery twrp.img
fastboot boot twrp.img
Now your phone will boot into twrp and you can install the Oreo zip rom into phone and enjoy using your LG phone again!
Thank you!
I've added this to the US998 Pie KDZ thread. That KDZ is very wonky. It's the only Pie people have problems flashing. Probably because LG has not yet released Open Market US998 and the one we are using is technically for U.S. Cellular US998.
I had no trouble flashing it myself -- on my backup V30+(former LS998) going straight from Nougat (never updated, it was my backup phone) to Pie through Dev Patched LGUP Refurbish mode. But lots of other people seem to have problems.
On my daily phone, I'm still on rooted stock Oreo with Magisk and Xposed mods.

I think part of my problem was the Pie ROM.
I have the US998 UCL version and I've read that the LG only released the Pie update for LG V30 US998 model with the Buyer suffix (1CL, UCL, UCK) and US998Z (UCL) only. But I could be wrong!

Right. LG has not yet released the Open Market USS98 KDZ yet. Theory is LG is waiting for the Sprint Pie KDZ to be accepted by Sprint. Open Market USS98 is the official North American carrier unlocked variant that needs to work with all carriers. So, Open Market US998 Pie KDZ (if ever released) will incorporate testing results from the long-delayed Sprint LS998 Pie KDZ (whenever it's finally released).

Happy for you bro . knew it wasnt toast since its us998
My friend has LG G7 ThinQ G710AWM 20d, Android 9, and I'm unable to enter into fastboot or recovery mode because I plan to wipe and install a custom ROM without all the bloatware and spyware. Tried ADB, button combos, etc. No luck. I've successfully rooted and modded other phones but I am stuck with this varient, please help!
UPDATE:
I think I need to cross flash to Android 8 Oreo, I am stuck at which firmware to flash from the LG site, there's a bunch of them listed for the model G710AWM all having different versions.
