I've got a cheap Chinese tablet (WM8850-MID) running Android 4.0.3 based on WonderMedia 8850 processor.
It's not rooted.
Here's what i found:
/system/xbin/su is present:
-rwsr-xr-x 1 0 0 68528 May 14 11:07 su
But I can't run su in a terminal:
su uid 10064 not allowed to su
Using adb.exe I have the same problem with uid 2000.
There is a script /system/etc/init.sh which is called a boot time, but If I modify and push it via adb it won't execute (lost execute permission)
adb reboot-bootloader does reboot the device, but it does not stay in bootloader mode and just go straight to Android.
I'm not sure where to go from here. Is there a way to root that device ?
Try ./adb root to run as root.
Use oneclickroot.

I forgot to mention "adb root" says I'm already root.
If I copy files with adb push, the owner is root, but If I use "adb shell" I'm user uid 2000.
This is a new tablet, but I'll give oneclick a try anyway. Thanks.
I've just tried SuperOneClick 2.3.1.0. It says it's already rooted because it can find /system/xbin/su, but I continued anyway. It can copy busybox (temp) but cannot change the permissions and it stops there.
Try resetting your tablet and if the su binary is stil there remove it. After resetting retry with superoneclick.

Thanks, but how do I delete it since I don't have the permissions? In case it's possible, is it safe to remove the su binary? I have no way to recover my firmware...
Use ./adb root to remove it because you will be root.After removing it reset your tablet to factory settings. It is safe because the su binary is not part of the os.
Then try rooting with oneclickroot.
Hope it works for you.
i also bought wm8850 tablet in china..can you teach me how to root in detailed its my first android device....i dont understand the other terms u are using....
Hi jallaine12gil,
I think that you should first try to root with oneclickroot. Post if it worked or not. Oneclickroot is a rooting program for android devices.
download the firmware. then find the android4.0.tgz file open it with 7zip, add the su file to system/bin folder and system/xbin manually.... then put the superuser.apk in the system/app folder then save changes.... then flash firmware from sdcard
if camera is in the top centre of the wm8850 tablet: in txt file
if camera is in top right of the wm8850 tablet: in txt file
download the firmware. then find the android4.0.tgz file open it with 7zip, add the su file to system/bin folder and system/xbin manually.... then put the superuser.apk in the system/app folder then save changes.... then flash firmware from sdcard

Extract the archive into sd card and insert into tablet and Power ON!

How to get adb working on the wm8850?
Hi, sorry to interject with something semi-unrelated, but how did you guys get adb working with the wm8850? I've added the vendor id to the ~/.android/adb_usb.ini on mac, but adb still can't find the device. I used 0x0ea0, is this what you guys used?
Any advice would be great!

Hi, friend
Sorry, how do you root??
Hi,
i accidently changed the permission of the folder "system" to READ only. atleast i think so... i used Yaffs Explorer to change permission of "system" and i ticked the first line on all 3.
again.. this was an accident cuz i didnt know what i was doing.
now the problem is my phone just keeps restarting ... and then it boots into recovery (3e) on its own...
i tried using ADB to change the permission with adb shell ... and all that.. problem is
adb works. phone connects and shows off as device.
but if i try using the adb shell command or any other command with adb ( except sideload ) it tells me
"PERMISSION DENIED" and similar messages...
i have no clue how to safe my phone now any help would be much much appreciated.
i thought something of my own...
is it possible to write a shell script which changes the permission of "system" folder to its correct one.. make it as a .ZIP file and update use it with "update from adb"
please any help^^
best regards
Krype
I assume you are rooted have you gone into CWM and reset permissions?
hi,
I still have adb access,
already tried to adb-push of the original build.prop backup back in place, it is actually uploaded, but won't boot anyway.
backup done by build.prop editor, and file pop and push from a linux machine (so no CRLF thing for sure).
attaching snapshot of logcat.txt
... *HELP*
thank you
the problem was in the file permissions. i had to remove write permissions to the group. (rw-r--r--)
You can fix permissions using adb

First of all DO NOT WIPE DATA / FACTORY RESET
This will remove adb access. Depending how far you can boot, do you get adb in recovery or normal. Can you use adb shell? If you can you can us adb shell chmod 644 /system/build.prop
EDIT:
Failing that try to install a zip. Sell my links for both current and older zips
Hello! I'm downloaded an app called LCD Density Modder, and i modified the screen DPI 240 to 210 and i get a bootlop.
I have a .backup file in a stocked recovery, but if i want to recover the backup, i choose recover from sdcard, and i dont see the sdcard, just the in-phone memory.
I have install update.zip via ADB, but gives me just adb sideload file.
Help me how to edit my build.prop via ADB sideload, or how to install backup from sdcard?
Thanks!!!
If you are rooted just use adb push to send the file.
How?

Okay, but how?! My phone gets bootloped, and if i choose the Install update via ADB, it just gives me sideload session
(adb devices, and list me with "sideload" prefix)
Rooted an Alcatel ONE TOUCH Evolve 2 and downloaded root explorer. i ran out of space so deleted /system/bin and /system/xbin thinking they were filled with stuff like busybox that i had downloaded. i try to open a shell with adb and it doesn't work. So i restarted my phone and now it only went to the white start up screen and nothing els. i used a adb to reboot into recovery wich is still t-mobile stock and reset to factory it didn't work and now i can't use adb except for sideload and i can't find the right version of kitcat . please tell me how to remotely turn on usb debugging or how to flash it please.
