    problem to dump rom on Freelander PD90

    Hello

    I want to try to play with rom of my tablet but, I didn't manage to dump update.img (that seems to be called backup, by the way).

    Here some informations:

    Code:
    root@android:/ # cat /proc/cpuinfocat /proc/cpuinfo
    Processor       : ARMv7 Processor rev 0 (v7l)
    processor       : 0
    BogoMIPS        : 2399.21
    
    
    processor       : 1
    BogoMIPS        : 2399.21
    
    
    Features        : swp half thumb fastmult vfp edsp neon vfpv3
    CPU implementer : 0x41
    CPU architecture: 7
    CPU variant     : 0x3
    CPU part        : 0xc09
    CPU revision    : 0
    
    
    Hardware        : RK30board
    Revision        : 0000
    Serial          : 0000000000000000
    Code:
    cat /proc/mtddev:    size   erasesize  name
    mtd0: 00400000 00004000 "misc"
    mtd1: 00800000 00004000 "kernel"
    mtd2: 01000000 00004000 "boot"
    mtd3: 01000000 00004000 "recovery"
    mtd4: 18000000 00004000 "backup"
    mtd5: 08000000 00004000 "cache"
    mtd6: 40000000 00004000 "userdata"
    mtd7: 00400000 00004000 "kpanic"
    mtd8: 28000000 00004000 "system"
    mtd9: 733a00000 00004000 "user"
    it seems rkdumd didn't work on rk3066 as I found information on another topic, so what can I do? Rkbatchtool didn't allow to make a dump, the only thing I have is an official firmware from freelander that I can flash with rkbatchtool but nothing else.

    Re: problem to dump rom on Freelander PD90

    Now I'm stuck on wendal's tools.
    Here is the content of my romdump folder
    [Only registered and activated users can see links. ]

    I use wendal's tools to try to unpack recovery.img as explain in this post [Only registered and activated users can see links. ]
    but I get an error :
    Code:
    C:\Documents and Settings\brunot\Bureau\RK29xxImageTools_v2.1>lua rk29xx_rom_too

    chmod: cannot access `system/app/Superuser.apk': No such file or directory
    Unpack -- All Done
    Pls input: 1-Unpack 2-Pack 3-Exit
    
    and here the content of my wendal's tools folder:
    Img2.jpg
    of course, Temp is empty, that is normal at that point as nothing works.
