    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.

    Ugh.. now I did it. After my previous post, I realized that I could just do adb reboot recovery. So in my infinite wisdom, I flashed the CM10 and now cannot get past splash screen. I figure no big deal, I'll just adb into the device... nothing doing. I get "device not found" and the usb is working fine (shows properly in device manager) even after killing/restarting/scanning devices. I am going to proceed into linux territory to try adb there, but I am not hedging my bets... I am truly afraid I bricked it unless somehow I can get into recovery using hardware buttons. I have tried several suggestions from forums referencing the A10 to no avail. I wish I had seen this thread before I tried CM10.

    UPDATE - adb works in linux (using sudo su), but no r/w to device and no reboot recovery (just boots CM). Looks like CWM is snarfed... I will keep posting updates.

    You can't boot into recovery from hard key combo, it has been disabled by the company that made d2pad, they have an option in settings to boot to recovery, or use the script I include with cw recovery.

    No I didn't use that CM9, I used my own port for 8042.

    I may port CM10 at some point, It will also come from my own ports.

    You installed Christian Troy's source, sounds like you are all set then, good luck.

    Did you succeed in getting ClockworkMod Recovery to work on the 09xxxx model?
