    I wasn't able to find a datasheet on it, what does the chip itself look like, can you post a picture of it? Hopefully its a TSOP instead of a BGA chip.

    If it looks like the picture on page 13-14 of the following document then you can short a few of the i/o pins with a flat blade screwdriver (very carefully), while you plug in the board. It should then show something like the following while attempting to boot, note the SD in the line. If you do that while having a sdcard inserted in the system it should attempt to boot off of it. You can remove the tip of the screwdriver once it starts to boot off SD.

    WARNING shorting the wrong pins probably can burn out the eMMC be sure to only short i/o pins.

    Code:

    It looks like either the BL2 is corrupt or your hardware might be bad. You should be able to try the eMMC pin short method to force a boot off of sdcard and reinstall the firmware and see if that fixes the problem.

    How far into the boot process does it show via the serial connection?

    There is another way but its potentially dangerous. You would need to carefully pin short a couple of the data i/o pins on the eMMC during the boot process.

    I didn't have to do any of it, I read somewhere to try on another sd card, I did, and it worked ! Thanks

    Looks like its all there to me:

    You will need three files: aml_upgrade_package.img, aml_sdc_burn.ini, aml_sdc_burn.UBOOT
    The "aml_upgrade_package.img" may be named differently depending on your vendor, its the original file that CustomizationTool extracts to the files above. It should be renamed to "aml_upgrade_package.img" and/or match what is shown in "aml_sdc_burn.ini".

    From what I recall after you open the img it puts the individual files under C:\Program Files (x86)\Amlogic\CustomizationTool\tmp\level1

    I disassembled the box.. but it seems that it doesn't have a serial port (pic attached) .
    Its to the left of the heatsink in the picture, but I can't see the actual pads in the picture, maybe due to being so close to it. You only need to hookup the TX / RX / GND wires. On my board it has a pin header already installed which made it much easier to use.

    The usb method is explained here: http://www.cnx-software.com/2016/11/...sucks-in-2016/
