Minix Neo X7 Roms for Tronsmart T428

[AndroidDeluxe]

First sorry for my bad english

Hi I have a Tronsmart T428 TV Stick but there are no more updates for it
At the moment I have "T428 KitKat Finless ROM 2.0" Firmware on my T428 Stick.
It seems to work good but there is a problem with sound (volume).
T428 and X7 seems have the same hardware specifications:
RK3188 Quad core, ARM Cortex-A9, 1.6GHz Max
Quad core Mali-400 MP4, 533MHz
Hynix DDR3 2GB, Frequence:1333MHz
Broadcom AP6330,Wifi 802.11b/g/n, Bluetooth 4.0

Only the NAND FLASH on X7 is bigger -> 16GB instead of 8GB.

So my question is: Can I use one of this ROMS on my T428?
MINIX X7 KitKat 4.4.2 CE ( Community Edition 2.1.0 )
QUICKSHOT V3.1 by The Nitro Team for Minix Neo X7
Minix Neo X7 - wasser firmware 1.0.4 - KitKat Android 4.4.2
Minix Neo X7 - Finless 1.9 ROM

Which ROM is the best at the moment for Video Streaming? Which can I use?
Can i brick my Stick if I use one of this ROMS? When yes, is it possible to unbrick it later?

I tried Wasser's 1.04 KK on my T428 and wifi worked fine but it wouldn't see the USB Tronsmart Ethernet dongle. For the brief period I had it installed it seemed to work well but since I want a wired connection to my router I went back to Finless 2.0 and the no volume control and static IP bugs. You can give it a static IP by the way, you just have to assign it from the router and not the T428.

The only minix X7 rom that I'm not able to install on my T428 is the KK commuity editio 2.1.0.

Awe darn... I was hoping to try this one too....

I'm chomping at the bit to give KK Community a shot on the UT2 3188T I have....just waiting for more of the bugs to be fixed....
