Subject: [Help/Info] Looking for original firmware for HKTRT2831P738 - Bootloop Issue

Body: Hi everyone,

I’m currently troubleshooting a device with the model number HKTRT2831P738. I picked this up recently, and after attempting a settings reset, it seems to have soft-bricked (stuck in a boot loop with the LED blinking but no display output).

Does anyone happen to have a backup of the stock firmware for this specific board? I’ve checked the usual manufacturer sites, but since this looks like a generic OEM unit, support documentation is scarce.

Device Specs (from the sticker):

I have an SD card and a USB-TTL adapter ready if I need to flash via serial, but I can't seem to locate the correct ROM file. Any pointers to a repository or a Dropbox link would be massively appreciated.

Thanks in advance!

Note: If you are unsure whether your device uses this firmware, always check the mainboard for a silkscreen label near the CPU or memory chip. Look for "HKTRT2831P738" or a short "RT2831" code.

Install Realtek USB Download Tool or RKDriverInstaller (depending on the RT2831 variant). Verify in Device Manager: “Rockchip USB Device” appears.
