I cannot boot into CWR on my US 32GB tablet. It just reboots normally. I used the 32 gb file about half way through the thread and just renamed it.

Code: 
# mount -o rw,remount /system
mount -o rw,remount /system
# echo "#!/system/bin/sh" > /system/etc/install-recovery.sh
echo "#!/system/bin/sh" > /system/etc/install-recovery.sh
# dd if=/data/local/cwr_ventana_2.img of=/dev/block/mmcblk0p1
dd if=/data/local/cwr_ventana_2.img of=/dev/block/mmcblk0p1
8696+0 records in
8696+0 records out
4452352 bytes transferred in 1.993 secs (2233994 bytes/sec)
# reboot recovery
reboot recovery
reboot returned

Try to press Vol-Up several times after powering on the tablet (when it vibrates short)

Is log finished when device have been rebooted? I understand that it reboots itself after about 15sec? Did you wait that long?

Credits go to Logxen for modifying and compiling (based on the builds jcase made).
Thanks to bohdans for webspace.

We also excluded the /data/media directory (Internal sdcard) so backups doesn't need so much space anymore.

I can compile ROW versions with my kernel. Can you tell me what steps you took to exclude /data/media(I'm quite new at this)?

Also, are your config files uploaded somewhere for the 32 and 64 gig models(I can generate only for 16GB at the moment)?

@realyst2k: Sounds like you are close to getting CWR to work on the ROW versions. It also sounds like you haven't been able to test it yet.

Thanks for the update. Everything seems to be working properly for me (32GB US version).

Is anybody else getting a "Can't mount backup path" error with this version?

You have to edit the source files to force this behavior. Its in the file nandroid.c near line 111:

if (strcmp(backup_path, "/data") == 0 && volume_for_path("/sdcard") == NULL)

Erase the second part of the if-condition. Something like this:

if (strcmp(backup_path, "/data") == 0)

Nothing unexpected in the log. Can you try to run the command adb shell cat /proc/kmsg while in recovery, wait until it reboots and post the output? Maybe the kernel is telling us something usefull.

So very interesting and odd. I loaded CWR and typed adb shell cat /process/ksmg and it started outputting kernel info normally. (I'll paste it in here later as I'm on my phone)

Anyway, it never rebooted, I waited at least a minute and decides to try a nandroid backup. Success! And no reboots. Strange I know but interesting and intriguing. I'll update this post later with the output.

Cheers.

Did you change anything? I had one of the reboots too at first boot of cwm, but it never happened again to me. The Bug seems hard to reproduce.

Thanks! I'll compile a ROW version tonight and give it a try. I'll post the link up if it works.

Nah I didn't change a thing. Other than type in that adb command. Yeah its odd. I'll play more with it when I get home.

    No warranties, no guarantees. If this ruins your device, your fault, not mine. Consider this a test build, backup important stuff manually to your PC for now (photos etc)

    This requires an sdcard installed

    Thanks for sharing this it worked great, except for the instructions I needed to use
    dd if=/data/local/cwr_ventana_2.img of=/dev/block/mmcblk0p1
    rather than
    dd if=/data/local/cwr_recovery.img of=/dev/block/mmcblk0p1
    to match the name of your file.
    Thanks again for sharing, CWR seems to be running perfectly.
    Also for those looking for root the exploit has been posted here.
