Raptor 2xxx 5.2.3

I try this process many many times but the result is always the same, camera reset randomly with the IR powered on and off
Have the same issue with my Chinese Hikvision 2032 after FW upgrade to 2.5.3.
Tried many FW versions with tftp, but camera only reboots.
 
The fw is the v5.2.3 and not 2.5.3, so I proceed to restore the camera with the interface TTLS RS232 because there is no other way to restore it! :(

Will update when I have performed the procedure!
