Install openwrt on Teltonika 955

Hi all.
I have Teltonika RUT955 old revision. I've encountered a problem: I can't install openwrt. After installing the image, the device constantly reboots.

Constantly in the same place:

[    0.304959] Block layer SCSI generic (bsg) driver version 0.4 loaded (major 251)

[    0.359957] printk: bootconsole [early0] disabled

Through U-boot, the system only accepts a factory image. Through cli with the -F argument i can install all images, but the result is the same.

there are two RUT955s at https://firmware-selector.openwrt.org/, are you using the right one ?

since you seem to have serial access, post complete flash and boot logs.

Yes, H7V3C0 is a newer revision. I have an older one.
