HK1 Mini RK3329-D4-V02 - hard bricked in maskrom mode - Test Device Fail

[rocky5]

Hello,
I have a hk1mini RK3229-d4-v02 20180613 in maskrom mode. All softwares are able to see it, but non of them is able to write a firmware, anytime it fails on Test Device Fail. I've tried on Win7 and Win10.

Hi ,

maybe the Loader is bricked or more , did you tried the SDWay to restore or boot

from SD , maybe the Haizenberg Way works for you ,
