    I am impressed, I had talked to Coby sometime ago they told me they would be taken actions eg modifying their tablets to prevent the use of the livesuite and to protect from a certain dev. So this is it, I have looked at your dump and see what they have done, I wont post how to defeat this security.

    I will warn you not to try any roms or any livesuite images, you will regret it.

    your rom is the newest that I have seen

    Ok download and flash below recovery, it will allow you to do what you want, again do not install any roms or livesuite images period.

    9740_secure_recovery_signed.zip

    After you flash new recovery, power off tablet wait 1 minute then restart tablet this will reset one lock on your device, and it will be able to work correctly.

    By the way, your rom is 4.0.4 while other roms are 4.0.3 so I may try and install your rom on my tablet to see if there are any improvements beside the added security.

    hello sir, thanks for your reply. here's what i did. i've downloaded 9740_secure_recovery_signed.zip then i "install zip from sdcard" then i select the file that you gave to me. then after i install, i turn off my device in 1 minute then i turn it on after i minute but i still back on cwm. did i do it right sir? sorry for bad english.

    ah sir, is there any software like livesuit that can flash my device even in cwm mode so i can use the file that you gave to me?

    are you sure you flash new recovery?

    do you have adb setup?

    You are doing it correct, just your cache isn't mounting so it's blocking the install.

    Ok you have adb working so lets go that route.

    download nand.ko

    place nand.ko on sdcard

    then mount sdcard in cwm

    note using adb type one line at a time press enter after each line, so the command is give to the tablet.

    open terminal

    adb shell

    busybox cp /sdcard/nand.ko /tmp/nand.ko

    chmod 644 /tmp/nand.ko

    insmod /tmp/nand.ko

    lsmod

    mount -t ext4 /dev/block/nandh /cache

    rm -r /cache/*

    now install 9740_secure_recovery_signed.zip

    Below is what the commands look like in terminal.

    Code:
    root@Vamp:/home/vampirefo/Desktop# adb shell
    ~ # busybox cp /sdcard/nand.ko /tmp/nand.ko
    ~ # chmod 644 /tmp/nand.ko
    ~ # insmod /tmp/nand.ko
    ~ # lsmod
    ~ # mount -t ext4 /dev/block/nandh /cache
    ~ # rm -r /cache/*
    ~ #

    look at above commands again

    insmod /tmp/nand.ko you are missing insmod from the command.

    try the commands again.
