i wish to share with others my 90% successful installation of atvx v2FF on my "firmware-dead" (= i've tried to change firmware without having the original one) device V9 Gomyhom S912 3gb 32Gb DDR3.
The way i used to upgrade firmware on this *GREAT* works of these guys is via BURNING TOOL : googling and find a tons of instruction to how to do it.
This is the device:
External device with cover
Lower cover
PCB with cooler on CPU /RAM
PCB Upper side
PCB Bottom side
Model printed on PCB
SAMSUNG Chip
AMLOGIC S912 CPU
RAM DDR3
WiFi Chip
DDR3 Controller CHIP (?)
Ethernet Chip
Remote
This device works at 90% but i dont know if the causes of the "problems" could be the device or the firmware.
In each case is fully usable with a lot of app except those do not work with rooted device (in Italy TIMVISION and INFINITYTV)
WORKING
-Video & Audio (that's a good start)
- WiFi
- USB Port
- SDCard
- HDMI 1080
- Remote (explained after)
NOT WORKING
- Ethernet Port
- Reboot
- Integrated Chromecast (may be my personal fault....)
- Bluetooth
NOT TESTED
- 4K - i'm just a poor boy and i dont have a 4k TV :|
SHUTDOWN : if done, the BLUE LED
turning OFF 
and you need to unplug / replug power connector because the remote power-on red key DON'T turn on the deviceREBOOT : if done, the BLUE LED
turn to RED LED 
and REMOTE power on key WORKS!! So, if you wish to turn off your device than turning on from remote, do a REBOOTREMOTE
The remote configuration file included in v2FF *DO NOT WORK* with this remote device.
The file named "remote.conf" in the folder /etc/ need to be replaced with the following file:
https://mega.nz/#!Iw8WDQxK!C4N-6qkr2HdU ... ECsaLzCwv8
Btw the downloaded file must me decompressed and file "remote.conf" inside the RAR archive MUST be copied into device system folder /etc/ *overwriting* the original one.
If you are unsure, before overwriting , rename the original file in something like "remote.conf.orig"
You need to install an APP like ROOT EXPLORER to do that and give them the permission to read/write in system folder!!!
After this , reboot your device (or unplug/replug power connector) et voilà.
I hope this information can help anybody have this device or a similar one.
