[UPDATED Feb14][How-To] Root AML8726-MX Generic Devices

JBolho · Feb 13, 2013

This is a (very) small how-to regarding Root on Generic (unbranded, mostly called "MID") Android Tablets with aml8726-mx platform.

This file was made originally for Ainol Novo 7 Crystal tablet, but it works (or should work) on all devices based on the following platform:

AML8726-MX System-On-Chip, AMLogic Meson6 gXX costumer platform
Cortex A9 Dual-Core CPU @ 1.5Ghz
1Gb Ram
Dual-Core Mali400 GPU
Android ICS 4.0.4 or JB 4.1.1

Other exploits have been tried, like Bin4ary's method, Doomlord's method, SRS Root, One Click Root, but all of them can't seem to work (for now) for these devices when Android ICS 4.0.4 or Jelly Bean 4.1.1 is present. So, if you own one of these devices, use this file to gain Root access.

1 - Put the zip file on the root of your SD card
2 - Reboot to recovery (with the device off, press the Vol - and Power button together until it enters recovery)
3 - Select (using Vol keys) "apply update from EXT"
4 - Select the file and run it pressing the Power button
5 - Reboot your device

You should see before Android finishes loading a small notification saying "Android is updating", and after it finishes loading, if you go to the App drawer, you should see SuperSU installed.

UPDATE:

It seems that some of these devices that come with newer versions of Android have EXT4 FS instead of UBIFS.
XDA Member Lannig has managed to edit the META-INF file of the "Crystal-Root.zip", re-compress it and re-sign it.
With his permission, and by suggestion of XDA Member AbliB, i'm posting Lannig's root file here in the OP, so that users with these AmLogic devices with EXT4 File System can have root.

Credits for the original root file (Crystal-Root.zip) go to Soulflier @ Slatedroid.com

Credits for the alternative root file go to Lannig @ XDA

Need your help, i have use your root and it works find, but not sure what i did, after it reboot, the system hang and the screen gets lock up. I have use the factory default but still not working. Not sure if you have any way that can help me to see what happen.
the volume button still works. i.e. press up and down i can still hear the tone.

I must emphasize, i am not blaming your root program, as it was working fine
I am only seeking your help as i believe you may have some clue on how to troubleshoot. Thanks in advance.

What happened exactly? Did the device boot properly after root? Or did this happen afterwards? If it happened on the first boot after root, than maybe this method is not suitable for your device, i suggest making a full factory reset (wipe cache and media partitions if the recovery has that option) and then do a factory reset in the recovery.

I'm trying to find out that myself, since my tablet is a generic unbranded device. For now i only have root installed and nothing else, only the standard recovery. Since your device is not as generic, try searching Slatedroid.com for enything related to it, they have a ton of topics on most low-cost tablets on the market, including Ainol's, Coby's, Zenithink's, etc.

It did root properly, the root works very well. its my own fault that after root, i download lots of apps and change the "boot animation" and also run fix permission using Clockwork and all hell broke loose after reboot. It was "bricked" as it even factory default also cannot work.

- Luckly i search the web for 3 days and finally able to find the original ROM + the tools from a Chinese website and able to use PC -USB - Tablet to reload everything using ImageBurnTool.exe.

Now my tablet is back to normal and with this ImageBurnTool, i have make it "brick" few time and still able to restore to factory default.
Actually i was thinking of sharing the ROM and the website here, but not sure how to do it.
It seems there is no Forum on Viewsonic VB100a pro, i wish to setup one to help other and share my experience.

NEXT8D12F

I have tried this on my Nextbook NEXT8D12F which has AMLogic 8726-MX 1.5 Ghz and the ARM Mali TM-400 GPU but didn't have any luck.

I put the zip on the root of a formatted microSD and put it in the tablet whiles its off. Boot into recovery mode then it says:

E:Bad bootloader arguments
"(null)"
E:unknown volume for path [/udisk/factory_update_param.aml]
E:Can't mount /udisk/factory_update_param.aml

So I select the option 'apply update from sdcard' and select the Crystal_Root.zip and it starts doing something then says:

-- Install /sdcard ...
Finding update package...
Opening update package...
Verifying update package...
E:failed to verify whole-file signature
E:signature verification failes
Installation aborted.

Anyone know what's going on?

Cheers.

Have you tried to re-download the file? What Android version do you have on your device? This is designed for ICS 4.0.4 or JB 4.1.1 and possibly 4.1.2. The error you're getting suggests that the file is corrupted but there is a chance of your device manufacturer has it's own Android customized version and some paths may be different from the generic Google version. (This happens with Huawei for example)

线刷 == USB to tablet. it is the only method when you have brick(no recovery menu) your Tablet
TF == put to sim card and use recovery menu
