[Q] Help unbrick AMLogic aml8726-mx tablet

[Futaba0rus]

Hi, i want some help with unbricking an aml8726-mx tablet. It's Prestigio Multipad Prime Duo, 7" 1024x600 tablet with 16gb internal storage and micro-sd card slot. It has only Power and + - volume buttons.

I've bricked it by flashing official firmware with default recovery. Entered recovery, made wipe, than installed update.zip from sd card. Progress bar started to move, indicating what process is on the way. And than in about 20%(no real percentage was in that recovery) tablet first freezed and than turned off. From this point there was no reaction on buttons, no display(even no backlight) - nothing. Connecting it to PC made the power on light flashing every 1 second(i guess). No device found by PC. I've tried turning on with - and + pressed, with both, without pressing anything - no luck.

So it was deep brick. Later i have found some info about 5th and 6th pins on NAND chip inside tablet, if those pins are connected to each other, after turning on tablet will be discovered by PC as M6 device. That worked! After hours dancing around AML usb flashing tool i was able to boot some uboot on tablet, started some recovery(not on the screen, it's still black as night), connect to recovery with ADB and trying to flash BOOT, BOOTLOADER and RECOVERY.

What i've tried:
1)adb push boot.img, boot loader.img and recovery.img i get from official firmware for this tablet

2)to make sure what my files now exists on tablet. I've pushed them to /cache/ so

#cd /cache/
#ls

and ls told me what my .img files are there

3)tried to flash

#flash_image boot /cache/boot.img

#flash_image bootloader /cache/bootloader.img

#flash_image recovery /cache/recovery.img

And here is a problem - each of those command gave me that:
error scanning partitions exit with code -1

I can't flash bootloaders and recovery. I've googled for days and still dont get it - why that "partition scaning" errors and what should i try.

If anyone can help me with that, or is there some different method of flashing it - i will be highly appreciated. I've used this tablet for less than a week and now it's totally bricked what i can't bring it back to life.

Managed to get my recovery back by adb over wifi offa the matricom website guide.

The process is really simple, but what can I do if the box don't get into recovery mode?

I power it off, insert the SD card, put the toothpick in the AV, connect the power but the MX2 never goes into recovery.

Is it all hope lost?

I had a similar problem, no recovery mode and fixed it when I found this at multi-tv

Get Sdcard.exe, uboot.bin and an image with the usual 3 files in it and extract the contents to your desktop.

Now you need an old windows xp pc or laptop and a sdcard of 4gb or greater
Start Sdtool and choose the uboot.bin and sdcard then press make sdcard
If the card is completed and it un-mounts remove and re-insert it, if it does not un-mount do a safe removal then re-insert it.
Now open the card and put uboot.bin, recovery.img, factory_update_parameter.aml and the image g18ref-ota-20140624.zip onto the root of the card (MUST BE IN ROOT NOT IN A FOLDER)

Ok now safely eject the card and power off your mbox / mx2 etc and pop in the sdcard.
Now power the box up it should boot from the sdcard, flash a new loader and update with the new rom

A few minutes later you have a working box with new firmware and xbmc already installed, and it's ROOTED.

To boot using external recovery? No, needs to be an SD Card. To flash a ROM while booted into recovery? Yes, you can load a ROM from USB by selecting it in the recovery.

Using USB to upgrade after Successful Recovery

Hi Benni,
I followed your method using 1.1.5+ and it installed fine and the old Matricom Android version was running. However, I was hoping once this was working to install the OpenElec firmware from a USB stick as I had done previously.

But when I go back the to system recovery menu, and goto 'apply an update from EXT' and then update from udisk - no files show up. I've tried on a different box (which has the OpenElec firmware on it) and the same USB does work.

I can see that the sd card is still showing all it's zip files when attempting to apply an update - does it have to be placed on the sd card after updating to 1.1.5+?

Thanks,
GJ

I apologize for the noob question in advance. Even though I've been on XDA for a long time I've never worked on a Gbox MX2 to I'm a noob all over again. Will flashing this rom give me root, or is there another exploit to gain root on the Gbox mx2. All android devices have there own little quirks and I really don't want to be foolish and brick this thing.

Thanks

WARNING, IF YOU DO NOT KNOW WHAT YOU ARE DOING, THEN DO NOT DO IT.

1) THE PROCESS IS ENTIRELY AUTOMATED.
2) NO NEED TO MANUALLY INSTALL ANYTHING ONCE THE PROCESS IS STARTED.
3) THE 2 ERRORS COMING AT THE END OF THE RECOVERY PROCESS ARE PART OF THE PROCESS.

AN IMPORTANT REMINDER:

If you can not follow the instructions correctly or you do not understand them, ASK BEFOREHAND on the FORUM and UNDER NO CIRCUMSTANCES PERFORM THE RECOVERY.

Under no circumstances should you do any manual installation of any of the files located on the recovery sd card.

The result may be a permanently bricked box with no way to recover.

If you manage to brick your box, it is your fault entirely. I did the recovery image for myself and decided to share it with community. Use at your own reponsibility.

I created an easy-install SD Card image from this ROM: Matricom G-Box Midnight MX2 v1.1.5+ (ROM DATE = 9th of August 2013)

The ROM was used for creating the special install SD card.

It is very simple to install, just insert a 4gb or larger SD CARD into Windows PC and use this program to set up the card:

DOWNLOAD THIS:
http://hddguru.com/software/HDD-Raw-Copy-Tool/HDDRawCopy1.02Portable.exe

Then use the extracted sd card image file as a source and set a target to your sd card (4 gb), it writes the image, close the HDD RAW COPY program and eject the card (SAFELY - choose eject from PC, right click menu + eject).

WARNING: THIS METHOD WILL ERASE EVERYTHING FROM YOUR MX BOX AND INSTALL A NEW ROM. USE AT YOUR OWN DISCRETION.

As an added BONUS this will UNBRICK your device in case it is bricked.

- Make sure MX device is powered off and power cable removed.
- Insert SD card you just created.
- Insert a match or a toothpick to reset hole - you will feel a click. (it is the AV hole in the back)
- Power on the MX box by inserting power cable, while holding the match in the reset hole.
- It will boot to recovery and start installing ROM.
- After finishing it will give 2 errors - these do not matter.
- Remove power cable and insert it again, the device will boot as MATRICOM MIDNIGHT G-BOX MX2

This is how the board looks from inside: (NO NEED TO OPEN FOR INSTALLING)

Hello
The essence of the problem - there is a device TV Box U6D
A standard set of AML8726-MX - G18REF - 1G / 4G
Upgrade led to brick :silly: - black screen
But !!! respond to the remote, that is, the indicator shows the ON-OFF
Looking for all sorts of ways, including #12 - yet
to no avail ... In the photo there Nand, and pads,
but then, all resources about this is written is very vague ...
Maybe you have a tip
Thank you in advance...

Prestigio PAD2411

Hey guys ! I have android stick PRESTIGIO PAD2411. I've tried to change firmware but it looks I totally bricked it. Blue led doesn't work at all. Device starts to boot and it hangs on the boot screen. You can see boot picture and nothing more happens. I tried to leave it for a few minutes but no result. Also I can not enter recovery.... To enter recovery I make the next steps: remove the power, press recovery button and hold it, then I insert power cable, after few seconds I release recovery button. But nothing happens (before I bricked device recovery worked fine). I've tried to create rescue sd, but no result. Please, advice !
