So I bought a media player again. It’s Vontar X96 mini with 1GB RAM and 8GB eMMC and according to rule “Don’t turn it on, take it apart!” it’s exactly what I did:
After assembling and turning it on, Android 7 popped up but this was not my target OS. I wanted to use LibreELEC so I followed installation howto: downloaded and burned latest image to SD card, replaced dtb file with gxl_p212_1g.dtb, and run reboot update from Android terminal.
Box rebooted into working LibreELEC, nice! Now I wanted to burn it into internal eMMC so I run installtointernal despite a big red warning on howto page and warning in the script itself, rebooted and… I got sad. The LED was blinking red-blue and the box stopped booting. I tried all voodoo recovery instructions (holding reset button, powering from both usb and adapter, with HDMI, without it…) to boot into upload mode where the box would be detected by a PC and I would use USB Burning Tool but nothing helped. I also wrote to the seller to get help, they’ve sent me USB Burning Tool, factory image and Upgrade instruction which was nice but it didn’t work either.
So I hooked up serial interface to see what’s going on inside
and the result was following:

The box was in a boot loop without accepting any input or keystrokes. Some guides suggest to short out some pins on flash chip but my eMMC has BGA package so this was not possible. I randomly shorted out some resistors and capacitors nearby the eMMC but without luck. I was afraid I’ll need to use JTAG which seemed quite hard to solder and there were no howtos for using this method. Then I took some time to rethink this.
The point of shorting out pins is to avoid detecting the eMMC and to force the main chip boot into upload mode. So to avoid detecting it, it should be enough to break the communication by grounding some of the DATA, CLK or CMD lanes. So again I took ampermeter (to see if I’m not grounding power lane), attached one probe to GND and with the other one I was probing pins around the eMMC chip. After few tries, the status LED stayed blue and the board got detected, bingo!
For those with the same board, it was this pin:
Now it was just a piece of cake, I connected it to Windows machine, grounded pin again and used the upload utility:
Of course I tried to run and install LibreELEC to eMMC again but this time it worked and I wasn’t able to simulate the boot loop again, even with uploading garbage to /dev/dtb.
Hope this guide will help someone, if you have some questions or ideas please leave a comment.
Bye!
Hello Danmman
I have the same probem.
Can you show which pin must I shorten with GND on picture please ??
Hi Giorgi, try to zoom in pictures in article. There is a red line marking the pin.
Hello,
I Already short to ground like your picture, but my light still got red and when i use USB Burning Tool I got Error on 2% Proced..
can you help me to explain more detail about all process because i’m not to much understand.
Thx Danman
If your box is detected (it must be when you are able to get to 2%) then it has to be some different problem. Maybe your eMMC is damaged, I don’t know.
I change my image with”x96mini_20171202″ and the process now error at 7% ([0x32030201]Uboot/Get result/DiskInitial error)
Sorry I mean now when i flash my x96 mini always got error at 7%
hello friend you have managed to find a solution to your problem with your box
Hello…
My Problem Solved by this trick…thx
i think my emmc was problem so after flashing done the problem now is boot loop
plz i have same error code in 2%…how to solve it?
Dear Danman,
I have same problem, my X96 mini LED is blue, X96 recognized by USB burning tool, but stuck at 7%:formatting. I could not load with SD card, which prepared with *.img file, HDMI on TV does not recognize Box, even LED is blue.
Do you have any suggestion??
Thanks and regards,
Thank you, a few month ago I tried everything but couldn’t get the box recognized by my PC.
With this guide I was able to reinstall the stock rom again. 👍🤗
I’m glad it helped 🙂
Hello,
I Already short to ground like your picture, but my light still got red and when i use USB Burning Tool it still not detected my device can u help me out how to make it detected?
Did you try connect serial port to see what it does?
Hello Danman first of all thanks for the information that you provided, I have a very strange issue with my X96 mini, It does not boot and LED remains red (should turn blue). Finally I found a way how to boot it up but I did not solve the problem, I found a repetitive way to boot it up and its very strange. while booting I am touching the base of the board in the area underneath the SD card port. When I simply touch it with my finger the LED turns blue and the box boots up. At first I thought it was a coincidence but I did it several times. I don’t think its a case of a dry joint but I am suspecting its a grounding issue. What do you think about it? Strange isn’t it? I am thinking of buying a more powerful power supply.
By the way after few minutes after boot up it will freeze and would need to remove the supply and do the same procedure in order to reboot.
Hello, with touch I think you cannot improve grounding, I would guess it’s a bad solder joint. Maybe ask in some electronics repair shop in your location.
Yes i think u might be right. In fact after posting the message I tried to solder some solder points. It took muck longer to freeze but still it did the same thing. I will try to see what I can do to solder al the points possible because most of them are very very tiny,
Thanks you sooooo much. My box is alive
I couldn’t have installed stock firmware back again without your post. Thank you.
I have a box x96 s905w and when I want to add the firmware I get this error *[0x32030201]Uboot/Get result/DiskInitial error, can give me some solution to my problem
Should I just touch the pin with the screwdriver? With what and how should I touch the pin and where is gnd? Plz explain thank you
Take a wire. With one end, touch the HDMI connector shield for example and with the other end touch the marked pin.
Hi I try the method and no lucky, I ground to case of HDMI and only red light , and USB flash tool not detected. Here a photo any can help ? Thx
https://ibb.co/hbwu1p
Hello, so far it have worked for many people. Does your computer detect the device? Do you have a correct (crossover) cable?
Hello thx for reply me, I’m using a USB cable of a external CD-ROM, this one have double power USB. Here a photo ,
https://ibb.co/jRRTYe
The program USB tool don’t detect nothing , I only get red light when I power x96.
Ah, that’s the problem, you need to use a proper USB A male to USB A male cable.
Hi, excactly was the cable, i homemade one using two males and cut, and worked!
thx for this nice tip!!
On the google drive link, there is no factory image.
Only USB Burning Tool, & Upgrade instruction.
Can you kindly tell us where to find the factory image.
Thank you
Hello, you can find that file here:
https://cloud.danman.eu/index.php/s/AfCq7HBC4pQNZdY
Many thanks for the file, but I’m not able to get a blue light . Solid red or flashing red (when I short to the gnd)
The market spot is not working. The one on the left disconnects the board from the pc.
Any other spot that I can check? I have the same board.
Thanks
Mine flashed blue in another spot which is right under the led indicator where you’ll find two very small black chip(don’t know what they are called).grounding one of them might turn the indicator blue.just poke around in that place and it may turn blue.but I was still unable to flash mine and the error still occurred.I hope it works for you.my screw driver couldn’t ground so I used a tweezer.
You are just shorting the LED and the blue light comes up. That won’t trigger anything unfortunately.
Thank you!
It also revived my x96mini after trying to use a modified 8.0-rom(what just led to a poor red/blue lightshow). Cool thing to get it work again just with a short piece of wire in minutes..
More info please.
Use burn card maker for repair it
