[Android Head-Units] ultradj83:
Dears,

I'm trying to do a full NAND backup on Windows with rkflashtool 5.1 (I can succeed on Ubuntu, but on Windows I have several errors).

Drivers are OK because I can read and write NAND with any other tools, but I need rkflashtool because it's the only one I know able to read and write the whole NAND to a single file from command line.

I'm on Windows 10 x64 build 1607.

On NU3001-01-H (CPU RK3188) NAND size is 7456MB with 512kB blocks, so

7456MB x 1024 = 7634944kB

7634944kB / 512kB = 14912 blocks = 0x3A40 blocks

Running as user or admin

rkflashtool r 0x0 0x3A40 > dump.bin

or

rkflashtool r 0 14912 > dump.bin

I'm returned

C:\Users\TSS\Downloads\SCS\Tools\Windows\rkflashto ol-5.1-win32-bin>rkflashtool.exe r 0x0 0x3A40 > dump.bin

rkflashtool: fatal: cannot open device

I really don't know what to do.

Any suggestions?

Thanks and best regards
