Nokia Lumia 630 stuck in flash mode

[bokikv]

After few years I turned on old Nokia Lumia 630, to transfer data such as photos and other stuff to PC. But when I turned on phone, after Nokia logo I get message UEFI Error1, and after that blue screen with sad smiley, and after that phone constantly restarting with same screens.
I partially unlocked bootloader with WPInternals, operation dont end 100% because phone cant boot to Normal mode.
I succed to enable Mass Storage but there is no data in my phone.
After that, when I connect phone to PC it recognizes as Lumia BootMgr, WPInternals also recognizes but I cant do anything, I think I bricked my phone. When I try to Flash Original FFU it says Flash Failed, if I try to unlock bootloader or restore bootloader it say custom flash failed.
Windows Phone Recovery Tool detected my phone before I tried anything with WPInternals, but now dont detect. When I connect to PC, phone automatically turn on, but always stuck on red screen, nothing happens, sometimes reboot but always same red screen after Nokia logo.
Tried hard reset with button combinations, but there is no exclamation mark, again same red screen.
I wish to revert this phone to working factory state.
Can this be resolved and how, or it is unrecoverable damage?

Hey there, I hope you are doing well.
If you want to recover your Lumia 630, start by retrying the FFU flash with the correct firmware file, ideally using the Windows Device Recovery Tool (WDRT) or WPInternals if WDRT doesn’t detect it.

Reinstalling Lumia drivers or switching USB ports, especially to USB 2.0, may also help. If these fail, using Thor2 (from the Lumia Flashing tool suite) via the command line could force-flash the firmware.

Thank You,
