    I have the same situation as with most people here. My x8-h is dead, neither does it respond to flashing with the error : [0x10105002]Romcode/Initialize DDR/Check decompress/USB Control setup error

    Are there a clear steps to shorting procedure somewhere ? I really dont want to throw away this box having paid so much compared to other cheap boxes I bought.

    I just did this to my box and was able to get the video signal to work again. I used a very thin screwdriver and stuck it between the grooves on the underside of the box. I started above the android's head and pried it up slowly until it became unclipped. I slowly went around the sides continuing to unclip the bottom from the sides. Once I removed the bottom panel I unscrewed all 4 screws that were connected to the main board so I could flip the board over and get at the TP13 and TP15 spots. I proceeded to bend the end of a paper clip so it laid flat over the 2 points at the same time. I plugged in the power and HDMI, turned on the TV and turned the box. After the light came on the box I touched the paperclip to the 2 points making sure I crossed the metal to both points at the same time. After a few second the android and minix screen appeared. I waited until the settings menu loaded and then shut it down with the button. I then proceeded to update the firmware on my PC through the normal prcceddure. Box works fine now. I used this video to show me how to remove the bottom panel only. Nothing else in the video applies to this procedure.

    You seems to be lucky with your box. Mine didnt respond for any number of trials. Just wanted to know
    1. if your box was bricked as well before this process? I.e. Nothing happened when powered on except for the blue led switching on.
    2. did you power on by pressing recovery button anytime during this process ?
    3. Were the pins shortened before powering on? If not precisely when is it supposed to be shortened ?
    Thanks in advance.

    All my box would do was the blue LED. Nothing else was working. I shorted the points after I turned the box on and no I didn't use the recovery button anytime during the point shorting.

    Are there similar TP pins on X8H-Plus also ?

    Did you find an answer?? Interested in same... I've opened the box but cannot find TP13 or TP 15 - X8H-Plus?? Are there any other options I can try on this box? It's a pity it stopped working just after 15 months - expensive box for such a short life span... any suggestions welcome!

    Has anybody figured out how to do this on the X8H-Plus? I've got a dead box that just flashes the blue power light for a moment before it goes out. It sends some sort of signal through the HDMI but it is just a black screen.

    I shorted pins many and many times but my x8-h not start. Another valid method?

    You probably need to quote the source where you copied this from as it makes little sense on its own.

    x8-h: managed to bring the box back to life booting from SD
    - armbian
    - lakka.tv
    - LibreELEC.tv

    all is great(er)!

    I thought it was bricked, but I found out only the eMMC is broken.
    while trying to re-flash using the USB tool, it would give errors and couldn't get past the 2%-4% progress.
    the good side of this is that it left the SPI flash wide clean and I could boot from the SDcard.

    it seems that the eMMC is the achille's heel on these boxes.

    so far I couldn't find an Android build that runs from the SDcard but time will tell.

    Would be grateful if you could you please tell where you obtained the ROM's or did you need to build them yourself?

    Thank you for the information
    Hope that everyone solves their issues with these boxes.:)

    tested the following on my x8h with Amlogic S802-H
    - armbian: Armbian_5.27_S812_Ubuntu_xenial_3.10.99_mate_20170322.img from https://yadi.sk/d/wc2jqGsHuKy48/Armbian
    - lakka.tv: Lakka-S802.M8.arm-2.0-rc4.img.gz from http://le.builds.lakka.tv/S802.M8.arm/
    - LibreELEC.tv: LibreELEC-S802.M8.arm-8.0.RC4 from https://forum.libreelec.tv/thread-2877.html

    uboot params required are different from armbian to lakka.tv or librelec.tv:
    - armbian
    setenv condev "console=ttyS0,115200n8 console=tty0 no_console_suspend consoleblank=0"
    setenv bootargs "root=LABEL=ROOTFS rootflags=data=writeback rw ${condev} fsck.repair=yes net.ifnames=0 mac=${mac}"
    setenv kernel_loadaddr "0x14000000"
    setenv dtb_loadaddr "0x11800000"
    setenv initrd_loadaddr "0x15000000"
    setenv boot_start bootm ${kernel_loadaddr} ${initrd_loadaddr} ${dtb_loadaddr}

    fatload mmc 0 ${initrd_loadaddr} uInitrd

    fatload mmc 0 ${kernel_loadaddr} uImage
    fatload mmc 0 ${dtb_loadaddr} dtb/meson8_k200b_2G_emmc_sdhc.dtb

    run boot_start

    - lakka.tv and LibreELEC.tv
    setenv condev "console=ttyS0,115200n8 console=tty0 no_console_suspend consoleblank=0"
    setenv bootargs "${condev} bootfromsd"
    fatload mmc 0 ${loadaddr} kernel


    the u-boot params could be preserved or a ready-made bootloader could be prepared but I'm travelling and don't have time for it right now.
    hopefully someone can pick this up and prepare it.

    Any luck with shorting pins on the X8-H Plus? I've tried pretty much everything.

    Trying to flash using usb burning tool - errors at roughly 5%
    SD card / .zip file method will not work
    Burn Card Maker method starts the upgrade then stops and will not continue.
    Opened TRWP on SD card - shows 0MB for /data, /system, etc. Changing file system to any type fails.
    Seems like a partition issue. Does anyone have any tips or is it bricked?

    Ken, I like many users are experiencing the same problem, mostly with our
    X8-H boxes but not one single person has being giving a response from anyone at minix? I just don’t understand how such a expensive piece of kit is jus rendered useless after 15 months of use, mine cost €180 and now it’s a expensive paper weight. I really just can’t understand why no one has even tried to offer a solution for us. Most of us, our warranty’s are up so there’s no going back to the shop with them. What are we suppose to do now? Jus throw them in the trash?

    it follows the business models used nowadays. if they keep supporting a design for too long, there's no new money coming in.

    I understand that’s the way things go nowadays, but to not make a attempt to even help with some peoples problem regarding this subject jus doesn’t make sense to me. U said in a previous post about using the SD card method and a bootloader could u explain as I’m not sure what to do?

    using the sd card you can only run Kodi / Librelec or a Linux distro, not Android.
    if you're interested in this, I'll need to spend some time to figure out a simple way to do this. Librelec might be the simplest way to go but I still need to try some things out to make this an unattended set-up.
