Have you tried to just install the ROM? Thats all I did, seems it came pre-rooted.
Thanks for the reply. I loaded it on my sdcard and rebooted it, but it just restarts as normal. Any other suggestions?

Does this have the official app market?
I'm sorry guys, I'm new to this and could really use some help.
I have a 7inch wm8650 tablet and I'm trying to root it and install this rom.
I've tried to root the tablet via z4root and Universal Androot, but when I type in su in the terminal emulator, it tells me "must be suid to work properly".
Is there an essential step I'm missing? I really would appreciate any help that could be given.
summary: you are executing the su that is in busybox and that is NOT the su we need to execute!
I also was stuck at this step but I am still using the firmware that came with my WM8650 MID originally.
My years of experience with unix (which came before linux) led me to suspect that in Terminal Emulator
when I typed su I was getting the su in Busybox which might be different from the su I really wanted
to run (I further suspect that the busybox su checks if it is running as root before it trys to change
to root which is crazy isn't it?). Indeed I found another su, and when I got it to execute I got the
# prompt that proves I have root:
$ export PATH=/data/local/bin:$PATH
$ which su
/bin/su
$ cd system
$ cd bin
$ ls -lt su
-rwsr-sr-x 1 root 10036 26264 Oct 29 16:21 su
$ su
su: must be suid to work properly
$ pwd
/system/bin
$ ./su
# whoami
root
#
I will give details of the above commands as best as I understand (probably too pedantic for
some but really helpful to others):
$ which su
/bin/su
the which command tells us what will be executed when we type a command, which is important
because there can be multiple executables with the same name: in this case I believe the su in
/bin/su is a link to busybox which then checks and reports that since it is not root it cannot
change (spawn a new shell?) with root privilege
$ cd system
$ cd bin
$ ls -lt su
-rwsr-sr-x 1 root 10036 26264 Oct 29 16:21 su
Look! Here is another su in /system/bin! I wonder where this su executable came from?
Well the DATE suggests to me that maybe it came from z4root because this was the day I
am working on this stuff. So I want to try to execute this.
$ pwd
/system/bin
$ su
su: must be suid to work properly
Still seems to be the busybox su executing, so cd to the directory is not sufficient to get the
new su to execute. Next try to use some syntax that is supposed to
always execute the command in the current directory rather than searching the path
$ ./su
# whoami
root
#
Success! The # prompt means that this shell is at root privilege! NOTE that the ./su also caused the
Superuser app to add Terminal Emulator to the (previously empty) Apps list. It prompted me and I
clicked on "OK to add" or something like that. Apparently that is how the Superuser app (HORRIBLE
idea to give it that name) works: an app has to ask for root privilege, then Superuser is triggered
and user is prompted to make sure it is OK for that app to have root privilege. Then app is
added to that list Superuser keeps. Perhaps?
I do not think this gets me any closer to using adb over usb with this WM8650 MID.
Has anyone who has the WM8650 MID with the 24 pin dongle figured out how to connect to
a PC? I think there is a false rumor that a cable exists to plug in instead of the dongle
because some other MID owners have a 36? pin connector that can use some Apple USB
cable for the PC connection.
The good news is that my cheap Inland 70141 USB keyboard works well in this WM8650 MID,
and so do USB memory sticks I have tried. But I really want to use adb! And nothing at
all happens on the PC when I connect the A-A (male-male) cable between the WM8650 MID
and the PC (I would expect at least some unrecognized device but totally nothing).
I have tried combinations of USB settings (Mass Storage On/Off, ADB On/Off) on the MID
but no difference.
Such a battle! Any ideas for abd? Thanks!
