What could be the problem?

as far i know an clone xprog firmware may destroy the content of MCU HC912D60
but if read/write success you can repair by flashing others dumps so
Anyway try by lift legs reset and bkgd
Report back
Well we will try until success
Good luck

Hi,
I lift up pin xtail.
Same problem.
The 9s12 adapter may not be good.

look for the oscillator frequency settings
RE: xprog 5.55 reading freelander problem - zmann - 27-11-2018
No, Xprog in secured mode uses clock from the adaptor, that the oscillator unit on the adaptor is for and also the clock option on this mode is absent.
This clock signal level is usually much stronger than the level generated by a x-tal of the mcu itself and override it if it was not disconnected. And this is the reason on the manual recommend not to prolong secured mode on each operation, and before mcu internal oscillating circuit is damaged !

Can the missing capacitor cause the problem?
Via DP4 read write OK.
