Hi, All. I've make brick X88 PRO B while update firmware. So, I'm trying recoverying from MASK ROM mode, PC recognized Rockchip USB VID/PID, but rockchip tool makes error like below, (in Admin mode with PowerShell or CMD prompt are same, even windows 10/11 ) using tool: GitHub - cpebit/rkdeveloptool-bin --------------------------------------------------------- PS C:\prog\rkdeveloptool-bin-master\bin> .\rkdeveloptool.exe ld DevNo=1 Vid=0x2207,Pid=0x320c,LocationID=201 Maskrom PS C:\prog\rkdeveloptool-bin-master\bin> .\rkdeveloptool.exe rd 3 Reset Device quit, creating comm object failed! --------------------------------------------------------- I'm tryed install a rockchip device driver but it not effects totally. GUI tools (like RKDevTool.exe ) also make error result. Please someone give me a hint that makes progress.... Thank you advance.
