[Fire TV Original Android Development] slack5:
I have a problem with my Fire STick 4k. Stick boots up endlessly, animated fire tv logo is shown on the screen and it never goes away. I bought the stick in february 2022, I belive it has the latest firmware since I never prevented it from updating.

I believe I have tried all possible ways mentioned in this thread in order to unlock the Bootloader an install TWRP and revive the system by flashing. Unfortunately nothing seems to work.

Now comes the interesting part.

When I connect Fire Stick 4k to laptop via USB cable, it gets recognised for a few secconds as: MediaTek Preloader USB VCOM (Android) (COM4)

After those few seconds the Stick disaperes from device manager and after few more seconds it gets recognised as a ADB device.

Does this mean that it could be possible for me to flash it using Spflash since the stick gets recognised as Preloader USB VCOM?

I would love to try to flash the Stick using Spflash but unfortunately I am not able to find the firmware file that could be used in Spflash.

I couldn't locate the scatter file for Fire Stick 4k either.

Is there anybody that could share the 4k Stick scatter file or the complete flash file that I could use in Spflash?

Or maybe there is a way to generate files for Spflash from ZIP files that are used for flashing via TWRP?

I cannot use ADB since I never registered laptop on the stick while it was working.

The only thing I managed to do is put the Stick in the Fastboot mode.

This is the info I pulled from the stick while in Fastboot mode.

Waiting for fastboot device... [FBSN:G4N0VM0812xxxxxx]
