Roborock S5max update failed

[TenonH]

Hello, I bought damage S5Max with boot loop.
I connected using rx tx to motherboard via Putty. It seems to me that something crashed on him and he lost part of the data. I've loaded him many firmwares from S7 to S5Max in different configurations. The memory is s34ml02g200tfi00 256MB NAND. The last one it loads is

Cool there were a lot of things going on while running the script (via putty)and at the end it reboots, after the reboot again as before boot loop.
Is there anything that can be done about it? Is it possible to abort the reboot and from putty upload firmware to it?
Is it at all possible to fix this board?
I'm assuming there is a software glitch of some kind.
The board is not connected under modules only through UART.
On the board is written RubyS-LB Main LV
