hey guys i wanted to ask what is the difference between EA and EA SWISS SARL

:confused:
[Android Software/Hacking General [Developers Only]] JBolho:
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

@ Slatedroid.com

Credits for the alternative root file go to

This works for my Viewsonic VB100a pro using 4.1.1

-------------------------------------

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.
[Android Software/Hacking General [Developers Only]] glennski_0104:
Thanks.,this worked with my coby kyros mid1060.,please tell me how to make system dump?.,then CWM?.,
[Android Software/Hacking General [Developers Only]] JBolho:
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.
[Android Software/Hacking General [Developers Only]] JBolho:
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.
[Android Software/Hacking General [Developers Only]] thye666:
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.
[Android Software/Hacking General [Developers Only]] JBolho:
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)

No sorry, i don't, i searched for a few days for it but found nothing and never searched again since. The one thing i would like to get is a different kernel compatible with these devices, so i could control the CPU speed better, but that kind of stuff is sooo hard to find for unbranded devices... :(

For now i'm sticking with stock rom, kernel and recovery.

[Android Software/Hacking General [Developers Only]] nuwanmw1988:
mine is onda v702 with same specs.But in the recovery it only has "install updates from TF card".i think thats external sd card.but unfortunately my sd card slot is broken.so i am unable to flash that way.so is there any other way i can root the device.using adb commands or something?

Before I proceed to this rooting method, is this method possible for TM-MID730 4.1.1 tablet device?

---------- Post added at 08:55 PM ---------- Previous post was at 08:44 PM ----------

Anyway in 4.1 folder, which of those two is the ROM? the other one has a file size of 400+mb O_o that's huge
[Android Software/Hacking General [Developers Only]] JBolho:
To know if this file will root your device, you have to see if your device's hardware matches the description (AML8726-MX board with Dual Mali MP400 GPU)

If this is your hardware, it's 90% guaranteed it will work. It's not 100% guaranteed because some manufacturers tinker with their Roms and kernels and change some key permissions, system file locations, and partition managing. Anyway, even if it does not work, it should not brick your device.

The Rom link you are quoting is for Viewsonic VB100 tablets, not your device, so even if this root method works for VB100's, you should not try other manufacturer's Roms unless you REALLY know what you are doing. Just an advice...
[Android Software/Hacking General [Developers Only]] JovieBrett:
Ohh yeah it is not the same as on mine's hardware description :( but anyway I appreciated your advice, thanks for the help!

[Android Software/Hacking General [Developers Only]] Lannig:
Hello - may I have some help here, guys?

This zip does install on my tablet but it does nothing. I've figured out why: my UTOO tablet is AML8726-MX based but its 4.2.1 Android uses an ext4 /system filesystem, not ubifs.

Based on update packages published by the manufacturer, I have figured out that I need to change one line in the updater-script to:

mount("ext4", "EMMC", "/dev/block/system", "/system");

Easy enough to modify the script and rebuild the zip file (yes I do this on a Linux box) but obviously I need to re-sign it.

All my attempts based on various tools and tutorials found here and there have failed, I get an "installation aborted" at the package verification phase, so I presume that it's not properly signed.

Can anyone please point me at the right way to re-sign the modified zip?

Thanks in advance.

EDIT : made it ! eventually. I've found a small signer.zip archive made by a user called Skelton on a french-speaking forum that contains a bat file and all that's needed to resign an APK or an update ZIP file (I don't have the link at hand, biut Googling "signer.zip Skelton" will find it).

What this script does really doesn't look very different from what I had been trying earlier, but obviously there must be a difference because it works !

Comments on this still welcome.
[Android Software/Hacking General [Developers Only]] mvita:
Hi Lanning,

As you have managed to get this updated and trusted, do you mind sharing the zip file which has the [mount("ext4", "EMMC", "/dev/block/system", "/system");] in it?

Hi there,

Tried to apply the original zip to another no-name AML8726-MX based tablet (sold here under Lazer brand, model MD 7305) with no luck.

This time the zip is plain and simple rejected (installation aborted). Although I don't get any specific message about the signature and I can't access the /cache partition to check the log, I presume that it's because the stock recovery won't swallow the test signature used to sign this zip.

Guess I'm stuck, am I not?

Geez... even no-name tablets come unrooted and with locked recoveries nowadays...

You just have to run in on your mac, pc or linux (i'm using a mac) and voila!!! it works buddies...

the motochoper requires to enable usb debugging , connect the tablet to pc via usb cable , and to check if ur tablet has the latest drivers installed .

i tried to do that , but when i looked in device manager , on my device said drivers are not found .

PLS HELP bricked Nextbook Premium 8 SE next8d12f

Hi,

I bought a Nextbook Premium 8 SE, model: "next8d12f", the device contains core AML8726-MX.

Finally, after the last restart from recovery device not start and now does not turn on at all, just a black screen and end.

Only what indications are there any hope, its that, when I plug the USB cable to the PC the Device Manager recognizable M6-chip or an unknown device .... I downloaded many drivers for android_winusb, rockusb, adb etc. but do not know which one to choose, when the device will not boot or image flashes

Can you please advise how to put this device to the original state, I do not know how to end and that the dead / frozen up of devices, doing so in advance thank you very much for any help ... thanks

That's weird, maybe something to do with your system that's blocking the files, but just to be sure try this:

Go to Slatedroid.com and check out Soulflier's thread on rooting the Ainol Novo 7 Crystal and download the file from there. If it gives the same error, then for some reason this is not the method for your device.
