Comfast E393AX u-boot fail

Hi, I have a Comfast E393AX, I installed openwrt v23.05.04, but it stopped working. When I start it using a UART cable I get the following:

F3: 1001 0000 [0200]
F3: 1001 0000
F6: 102C 0000
F5: 480 [1000]
T0: 0000 00ED [010F]
System halt!

How can I restore u-boot?

Can you detail what exact files and how you installed?

I followed the steps indicated in the following link:
https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=9ac1523062a5818e566627ad4cbea6f3f5114387

I created the image with the command make menuconfig

After running the command:
sysupgrade -n -F /tmp/*--mediatek-filogic-comfast_cf-e393ax-squashfs-factory.bin
the computer rebooted and no longer loaded the operating system
