    There are two versions, The one I have has the D201208Bxxxxx S/N on back.

    rhg135 version is for D201209

    My recovery is for D201208 , the first thing to do is make a backup.

    You need adb installed and working.

    adb shell

    mkdir /sdcard/dump
    cat /dev/block/nandc > /sdcard/dump/boot.img
    cat /dev/block/nanda > /sdcard/dump/bootloader.img
    cat /dev/block/nandg > /sdcard/dump/recovery.img
    busybox tar -cvf /sdcard/dump/d2_system.tar /system

    once done,

    make a folder on your desktop navigate there through terminal

    adb pull /sdcard/dump

    now download recovery

    dc_recovery.zip this recovery is for 08 version

    d209_recovery.zip this recovery is for 09 version

    to install is just like any other a10

    download zip extract

    must be rooted

    adb remount

    adb push recovery.img /data/local/tmp/recovery.img

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

    adb push reboot-recovery /system/bin/reboot-recovery

    adb shell

    chmod 775 /system/bin/reboot-recovery

    chmod 777 /data/local/tmp/install-recovery.sh

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

    /system/bin/reboot-recovery

    Or you can use a file manger with root privileges, and copy the files where they need to go and set permissions on them, once you have done that.

    then install a terminal from market.

    su

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

    /system/bin/reboot-recovery

    once in recovery

    volume up to scroll

    power to select

    volume down is back

    d209_recovery.zip recovery build provided and supported by rhg135

    once you get cw recovery installed make a backup using cw recovery.

    I have uploaded the newer apps that come with the lastest update, also include playstore, youtube, filemanger and such.

    you need to do a factory reset in cw recovery before installing. d2_playstore.zip

    place on sdcard install via cw recovery.

    kernels is different, the tablets are different.

    volume down key is back key, volume up key scrolls

    anyway run same test I had you run for power button, post volume up and down key output.

    volume up on this recovery is 114 volume down is 115 power 116.

    I have the D201209xxxxxx version. So I am assuming the recovery you made for your version doesn't work with this model?

    I don't have that version. According to rhg135 the recovery doesn't work, but you could try it yourself and see if it works for you.

    The easiest way will be to download/install the google SDK and the USB driver package... you SHOULD then be able to use a windows-based ADB.exe in a command prompt to access the tablet and do the install as shown for Linux.

    You could install a file manger and remove what you don't want.

    Below is my current setup. the d2pad has a system of 503.9M I am using 228.7M so not much bloatware on my setup, I replaced the factory rom with CM9, I don't remember how much system was used via factory rom

    root@android:/ # busybox df -h
    Filesystem Size Used Available Use% Mounted on
    tmpfs 407.1M 60.0K 407.1M 0% /dev
    tmpfs 407.1M 0 407.1M 0% /mnt/asec
    tmpfs 407.1M 0 407.1M 0% /mnt/obb
    /dev/block/nandd 503.9M 228.7M 275.3M 45% /system
    /dev/block/nande 1007.9M 194.5M 813.4M 19% /data
    /dev/block/nandh 126.0M 4.1M 121.9M 3% /cache

    Hello all, I'd like to take a stab at compiling CWR for the 09Bxxxxx model. I do know how since I've made recoveries for the optimus slider. I have checked out the code as per [rom] CyanogenMod 10 - SlateDroid.com but I'd like to know how I can modify keycodes? This would be a great boon for 09Bxxxxx owners.

    I would much prefer CM... I assume you used this one from XDA, correct? I also found a CM10 release here BTW.
    Also, I cannot for the life of me figure how to cold-boot into recovery... I have tried all combinations of PWR + VOL +/- etc. No luck. This in itself makes me nervous about goofing around with ROM images.
