Firmware Sei800AMXAR ROM LIBRE - Sei800 ROM LIBRE

Gran trabajo!

Does it work on the 4K TV BOX 1.GEN Model : SEI800TFAS ??

I have a SEI800TFAS (4K TV Box 1.GEN, Odido Mediabox, Amlogic S905X4, 2GB/16GB). I bought it second-hand and I am not in the original country. I tried flashing a modified firmware and the device is now bricked: no LED, no display, but the PC still detects it via USB (Mask ROM mode likely works).

I saw your SEI800AMXAR ROM on the forum. My questions:

1. Is this ROM compatible with SEI800TFAS? Has anyone tested it on this model?

2. If not, do you have or know where to get the original/stock firmware for SEI800TFAS?

3. What is the exact process to purchase and receive the password for the AMXAR ROM?

I want to avoid bricking the device further. Any guidance would be greatly appreciated.

Thank you.
