    I just got my 8042 today,all help here, so far is only for windows users, "LiveSuite", if you are happy with livesuite you may use it, however it has two major set backs, one it's only for windows users, second if your usb malfunctions you are out of luck.
    I have read through most of the 8042 threads, and have taken from them what I needed, "temp root", from that we can do almost anything.

    What I will be covering in this thread is how to root, install recovery, install a modified boot.img, install a custom rom. all without using "livesuite"

    You should check your boot.img md5sum, if your boot.img md5sum doesn't match eda433b85d9729422a4be5889982d46d this update isn't for your tablet, you can still root and install recovery, but not update nor boot.img

    you will need adb setup and working, I am a Linux user, don't want to use windows to modify my tablets.

    Anyway lets begin.

    download 8042_root_recovery.zip

    8042_root_recovery.zip


    extract to your desktop you should have a folder called data, and a text file root_recovery, it contains the following commands. type one command at a time allow each command to finish before typing next command.

    The first command is simply coping the contents of the data folder to your tablet, the second command is asking for shell, third and fourth commands are setting permissions, fifth command is sending exploit, sixth command is asking for root permission, seventh command is installing recovery, eight command is booting into recovery.

    open a terminal

    adb push data /data/local/tmp/

    adb shell

    chmod 0777 /data/local/tmp/mempodroid

    chmod 0777 /data/local/tmp/install-recovery.sh

    /data/local/tmp/mempodroid 0xd7cc 0xad27 sh /data/local/tmp/root.sh

    su "Note at this point you can backup your system, recovery and boot.img, you don't have to but you might want to, see note 1 below."

    /data/local/tmp/install-recovery.sh

    /system/bin/reboot-recovery

    once in recovery

    volume up and down to navigate power to execute. silver button is back.

    at this time you should make a backup.

    download 8042_boot.zip

    8042_boot.zip


    adb push 8042_boot.zip /sdcard

    then use recovery to select install zip from sdcard and install it.

    reboot

    download 8042_update.zip

    8042_update.zip

    place on sdcard

    adb shell reboot-recovery

    select install zip from sdcard and install it.

    credits

    steev

    saurik

    fun

    If there is anyone that I left out of the credits, please let me know so I can give you credit for any work that I might have borrowed.


    Note 1 if you want to backup your recovery, boot.img and system before making changes run commands below.
    adb shell
    su
    mkdir /sdcard/dump
    cat /dev/block/nandc > /sdcard/dump/boot.img
    cat /dev/block/nandg > /sdcard/dump/recovery.img
    busybox tar -cvf /sdcard/dump/8042_system.tar /system

    then use either adb pull to put them on your pc, or mount the tablet with the pc.

    after recovery is installed

    to boot into recovery from shutdown

    press an hold volume up + back press power release power at coby screen keep holding volume up + back until you see cwm screen.

    to get into recovery from normal mode download terminal from market

    su

    reboot-recovery

    or from adb shell

    reboot-recovery.

    Vampire, if I change the files in your zips for those extracted by me will it work? It works for any Coby tablet?
    For example: If I get my boot.img and overwrite your 8042 boot, my recovery.img, overwrite your root_recovery and system and overwrite that in the update file will it work?

    Thanks Vampire, I was already changing the files and I was just waiting for your answer. Fortunately I did nothing.

    You would want to use the 9742 files instead.

    what app is telling you the rom isn't rooted? I don't use the superuser app, just su binary, if you want to use superuser app, you would download that from market

    download any terminal from market

    open it type su

    you should see

    #

    which mean root.

    you think a reflash would fix it?

    Since I'm using a Windows PC, are the commands any different, or would I be able to use this guide? I'd rather not mess with Livesuite, if possible. I've used ADB before with success I just don't know all the commands.

    Thanks.
