I am unsure if that is an option anymore...
1) After setting up the SD card with the signed CWM, I only get a white screen; should I set the SD card up with a stock recovery img?

2) I am only able to access the device through adb in the SD card recovery, when I run an edited install-recovery.sh, with my stock recovery img, the console flashes 'done' in a split second. Rebooting afterwards leaves me with a black screen.

3) I still see the Coby logo at boot; I can see /dev/block/nandg when I ls the directory; I have no idea how I can replace my recovery using the tools available to me.

I have uploaded my edited sh file as well as my stock recovery img.

And I guess my final question is....

Would you consider this to be a 'worthy' successor to replace the 9742-8?
It seems to be roughly in the same price range, with comparable features...
http://www.amazon.com/Arnova-Tablet-Switching-Technology-Multi-touch/dp/B00K547OOG

It seems it is an ArchOS elements tablet, with a rockchip cpu, it seems to have a rooting method, as well as a custom ROM.

I have the most expierience with this tablet, to be honest, so i was just reaching out for a word of advice on the issue. Should I replace the Coby, or 'upgrade' to an ArchOS, and re-reoot the new tablet using the guide posted here:

You need to post output of mount.
Is adb root?
Stop using scripts use commands as they should show output.
ls
mount
busybox
and so forth.

Thank you for the response.
Here is the output; I assume I have a root shell since I can push files....
I can confirm that busybox exists and functions, I had to use to run a few .sh files.

Code:
:>adb shell
~ # mount
mount
rootfs on / type rootfs (rw)
/dev/root on / type ext2 (ro,relatime,errors=continue)
devtmpfs on /dev type devtmpfs (rw,relatime,size=156944k,nr_inodes=39236,mode=755)
tmpfs on /dev type tmpfs (rw,nosuid,relatime,mode=755)
devpts on /dev/pts type devpts (rw,relatime,mode=600,ptmxmode=000)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
~ #

I only have access using a CWM prepped microSD. I can access adb shell, but only when the tablet is in recovery mode via this SD. I still wonder if I should rplace the recovery on the microSD with my stock recovery, because for now I only get a pure white screen with this card, and a pure black screen when the tablet is powered on without it.

Other than that, maybe I need to mount the right partitons with r/w access so i can truly overwrite my recovery with the original signed CWM?

You should try and mount cache and system via adb.

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

mount -t ext4 /dev/block/nandd /system

then I need output confirming mount.

mount

busybox df -h

only nandg exists in /dev/block...

but I will post the output of those commands below:

Code:
:>adb devices

~ # mount -t ext4 /dev/block/nandd /system
mount -t ext4 /dev/block/nandd /system

~ # mount

I am of course assuming that replacing the CWM on the SD with my stock recovery would yield the same results. As for the other two commands, there output is here, as well as the output of 'ls /dev/block':

Code:
~ # ls /sbin
ls /sbin

I don't care for any of your output, it's not good, upload your stock recovery and boot.img.

are you using your kernel from stock recovery? if not you should try using it, your results show only that sdcard is working, no communication to tablet. Basically you are just talking to sdcard, which can't do anything if it can't communicate with tablet.
