Box Beelink GT1 Ultimate S / N AX12, restarting after ROM update

[beliasneto]

Hello!

I have a Beelink GT1 Ultimate, Android 7.1.2, build version of 708N0 firmware.

I changed the ROM using the "[ROM] Beelink GT1 Standard and Ultimate Android (7.1.2) ALVATECH (both 6255 and 9377)."

Now, when the Box restarts, it will run for approximately 2 minutes and restart, sometimes at the time of restart it will lock in logo android. Having to turn off the power.

I've done recover, but it's not resolving.

Could someone help me with this?

Thanks in advance.

Note: I updated the ROM using a micro SD card. Using the Burn_Card_Maker program
