Boot problem - hangs on line at bl31

I have a radxa0 that I installed LineageOS on, it worked fine. Asked for an update, when I saw it, it crashed and doesn’t start anymore.
It’s in Maskrom mode, I’ve tried u-boot.bin, radxa-erase-emmc.bin, among other procedures, and it doesn’t start, neither through SDcard nor eMMC.
in the console I verified that the initialization stops in the line “Run into bl31” according to the following log:

run into bl31

After that, it stop and not change to USB storage or fastloader.
Can anyone help to solve this problem?

Please download the following loader and try again. We did some update to it a while ago:

Hi,

I had already done this procedure and it also did not work. Stop at the same stage.

Your board might have hardware issue then. Please contact your original seller for RMA.
