    [Help] Use AXP to flash ASUS TF101 gets "rcm version 0x4 usb write failed" message

    Hi all,
    I buy one ASUS Transformer TF101 16GB Wifi version (SN: C20KAS, SBKv2) recently and want to use AXP method to flash my tablet.
    When run "download.bat", utility always shows "USB write failed" error message (Please refer the attached picture) and the USB device "NVIDIA USB Boot-recovery driver for Mobile devices" will disappear automatically.
    I try to search data in google and this error message seems be caused by SBKv2. (can not confirm, just guess)
    Is there any method or nvflash utility that I can flash my TF101 with AXP method?
    Any help is appreciate. Thanks.

    Tried but fail ROM image:
    1. NFVlash of the 3.2 Build of OS -->FAIL (show usb write failed message)
    2. asus_ics_tf101.tar.bz2+Win7 OS--> FAIL (show usb write failed message)

    TF101_SBK_check log:
    t@ooo-P55A-UD3P:/mnt# ./sbkcheck
    Found APX mode device
    Chip UID: 0x43c7008423fc217
    Detected SBKv2

    Download.bat Content:
    cd %~dp0
    "nvflash.exe" --bct transformer.bct --setbct --configfile flash.cfg --create --bl bootloader.bin --odmdata 0x300d8011 --sbk 0x1682CCD8 0x8A1A43EA 0xA532EEB6 0xECFE1D98 --go

    sbkv2 is blocked from nvflash. you need a tablet with sbkv1 in order to use it. b7O was the transition serial number. some have v1 some have v2. i have a b7O 32g and got lucky. my friend got a b7O the next day and wasnt lucky.
