[Upgrading, Modifying and Unlocking] drggong:
Hi, I was trying to make a back up using rkDumper 1.1.1.0 from RK3568 chip.

However, I configure with two problems.

1. Using RKDevTool - ReadChipInfo, it says that the chip Flag is RK3568.

But in the 'rkdumper.exe scan', with VID = 0x2207, PID = 0x350a, it says that the chip flag is RK3566.

Is it available to make a back up for RK3568 with RK3566 chip flag ?

2. When I tried to make a backup using 'rkdumper.exe dump', it showed ' Command to read Failed'.

I had seen some threads about this and I followed your solutions, for example; change USB ports and downgrade drivers, but it didn't work.

And for RK3568, when I downgraded the driver to DriverAssistant v4.4, it couldn't search RK3568.

It was only be searched by DriverAssistant v5.1.1 which was given by my vendors.

In this situation, how can I try 'rkdumper.exe dump' for RK3568?

I will be really thankful if you give me answers about these!

спасибо !

I will attach my log
