Lg k7 x210 wrong root hardbricked

Hello guys and congratulations for the forum.
I have a problem with a LG K7 X210: I accidentally booted with Aristo 2 Boot and now the LG logo remains fixed and does not turn on.
The only accessible mode is fastboot or recovery mode.
I tried to flash with fastboot flash boot, cache and recovery but it still does not work. I found this version MT6580__lge__LG-X210__m13g__5.1__ALPS.L1.MP6.V2.19_ARIMA6580.WE.L_P42
If I try to flash the preloader or to unlock unroot oem i receive FAIL.
If I try with flash tool, it does not recognize it.
I kindly ask you for help, thank you
There's still no solution I'm still with the HardBrick...

Try this to see if it works for you, I do not know if they work because I do not have the device but it was the only thing I managed to find, paste the spaces in the url so that they can access the page
Did it work for any of you?

Lg phone Bricked

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.

You should ways check out the ROM specs before a flash always. Not only that NEVER flash a rom for another device unless it's confirmed to work with it. You may have had some bootloader related partitions flashed and borked the whole device

LG G7 ThinQ LM-G710AWM - Unable To Fastboot To Unlock Bootloader

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.
