Rooting trouble with Epad ZT-180 - Android Q&A, Help & Troubleshooting

Ok I have tried many times to root my Epad with no luck. It is a Epad with 512 ram 4gb internal flash and Zt-180 processor. Thing that I have tried z4 root failed trys but then when pushing root it stops and reboots. Universal root it says that the device is rooted and installs super user app, but i go to root explorer and it will not let me rw mount. And I have tried to use adb to push but I get the error can not connect please help thanks

Hi I have the same ZT-180 , 512k - 4Gb... Running Android 2.2
I have been able to root it, but had to use the Android SDK - ADB, and I needed to download the ARM6 version of busybox and a version of SU I found on this forum.
I've attached a zip of the files I used.
Unzip the zip files onto a USB memory stick.
Put the memory stick into the ZT-180
Make sure your ZT-180 is connected via Wifi or the network cable
On the PC, open a command prompt
CD to your android SDK tools or platform-tools folder
use the next 2 ADB commands
ADB connect (the ip address of your ZT-80):5555
ADB shell
then run each of the following commands in the ADB shell (cut and paste them into the ADB shell, and press return)
After the reboot, the ZT-180 should be rooted.
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
mv /system/xbin/su /system/xbin/su_original
mv /system/bin/su /system/bin/su_original
busybox cp /udisk/su /system/xbin/su
busybox cp /udisk/su /system/bin/su
chmod 6755 /system/xbin/su
chmod 6755 /system/bin/su
reboot

Thanks a lot, i followed your instruction and my zt-180 2 is finally root

---

Thank you RogerClark so much!

---

Many thanks, this is the first 'su' topic that made sense, easy to read and worked!
One question, just to confirm, in doing this java code can now run stuff as super user making my system open to attack?
It's only a play development system so not that bothered.

---

this worked for me too, many thanks
Something to watch out for which may well stall some who try this - if at some point during the process of entering the commands via ADB shell you receive a failure message 'no such file or directory' - just ignore and persist to the end. Took me some time and googling to discover this.

I dont seem to be able to get root explorer permissions even after completing these steps successfully :-( Ive tried reflashing with latest flash "10inch_DDR512MB_android+2.2" running above script -> installed root explorer but w/r button wont toggle and stays on r/o. I can install all root apps ok like busybox & others so not sure what you did or full steps you took to get root explorer w/r to work.. i also tried installing z4root 1st then above script and no go, same with androot... managed to get w/r working once before reflashing but noticed it only let me r/w on root and not in subfolders and files in those subfolders so couldnt edit my wifi config.. Any ideas?
EDIT: I reflashed unit again-> followed this manual root guide for V2 zt-180 ( cant show url cause im new here.. that sucks xda!! ) grant root access, tested in terminal that root access ok using su command (usually i would get "file link error: following process above!?) still root explorer fails to detect device is rooted even though i can install all root apps ok..lol.. I wanted to edit my wireless TX to be 20 instead of 100 to save power/improve reception(well known tweak for zt ) so then i mounted system in adb (mount -o rw,remount -t yaffs2 /dev/block/mtdblock1 /system) loaded Android commander in windows -> pulled RT2870STA.dat to my windows box, mad the edit to 20 and saved -> used root explorer on zt to delete RT2870STA.dat ->pushed edited RT2870STA.dat back into zt RT2870STA folder -> remounted read only in adb (
mount -o ro,remount -t yaffs2 /dev/block/mtdblock1 /system ) -> rebooted zt and tested modified wireless ok.
So I guess i can at least follow this process for any other file edits that require root access in subfolders of root drive(\).. until someone suggests an easier solution..

When you run the console on the ePad and type su what message do you get? If it's rooted you can run the su prog, if not will say you don't have access.

---

RogerClark, I followed your steps. And my results are kind of mixed.
Please help if you can.
I am running the ZT-180v2 512mb 4GB
I also did the 2/25/11 Flash upgrade
When I run the "Root Check v2.1" by joeykrim from the Android market it now says that I have root access and busybox installed.
However, Root Explorer 2.13.4 says "Root access coould not be obtained su failed with the following message: Make sure you granted root permission when requested by SuperUser"
Titanium Backup seems to have root rights.?
Any input??

---

I have the same pad and the same problem. I have root access, only root-explorer version 2.13.4 says I don't. I'm seeing it I can get an older version of it and see if it works. The first time I rooted my pad I had an older version of root-explorer that did work.
Will update my post if I get it to work...

update SDK
be sure after installing that you update all installed packages in the SDK Manager. i could not connect until i updated all a few times.
great post. Got root. Thanks a lot.

---

Now my 10" V1 zt-180 is rooted I can run su from an application and so do root stuff, but what I need to do is elevate my running app to root user. Any ideas?
P.s. I rooted my device a 2nd time after installing 2.2 with no problems.
Thanks.

Is there any way to back the rom before it is rooted?. So if anything goes wrong I can return it to the original state.

Download the 5-3-11 rom, if anything goes wrong, just flash that and start over with the newest rom. 5-3-11 fixes most of the issues.
