Tablet Yoga Tab 3 X50F does not pass the logo

Try to install a firmware with qfil the process finishes successfully but at the time of lighting it remains in the logo; I enter when recovering stock and it shows me this error.
Some solution or is a brick?
From already thank you very much

I can't boot my phone into TWRP recovery.

Okay so, i unlocked bootloader, booted my phone into "reboot bootloader" mode and installed TWRP Recovery for LG G6. Then when i try to boot it into recovery mode (twrp) it boots right into factory data reset. what do i do?
What i did was:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}

Can't add a custom recovery

I was able to fastboot into TWRP:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
but when i reboot, the standard recovery boot returns. I tried to install the no-verify-opt-encrypt but:
errors as well as anything i install. Any ideas? I am running Android 10, Oxygen 10.0.1

What's the model number of your phone?
Is this red screen occuring while booting into TWRP only? Is the phone booting normally into the OS?
