bricked CX-919, please take this as a challenge

[vehe]

Hi all
I have a challenge I would like your help with.
I bought the Cx-919, and after a day or so I've decided to flash it with a better ROM.
Searching the internet I found this ROM, and decided to give it a chance:
http://freaktab.com/forum/tv-player-...921-and-cx-919
But since I had some bad flashes of tablets and phones in the past I've decided I would need a backup of my current rom.
I've accomplished this by using this method:
http://freaktab.com/forum/developmen...ew-rk-2-1-tool
I did it twice, just in case I did something wrong.
By this time I had no problem with the drivers, I have installed them successfully and both the RK2.1 and the finless ROM flash tool V 1.37 had no problem finding my device while it was connected to the computer.

When I started the flash itself things started to go bad.
The finless ROM flash tool V 1.37 log had said-
Start to run
Start to test device
Test device ok
Start to download IDB ok
Download IDB OK
Start to reset the device
Reset device failed
Device not found

And after that the status bar at the bottom said no found RKAndoroid rock usb.
I have waited for about 6-10 minutes thinking this is part of the process, before trying re -find the device.
Also the LED of the device had turned off.
I've tried to reattach the device but with no success, the computer just did not recognized my cx 919 attached.
I have tried to restart my computer, reinstalling the drivers, attach the cx 919 to different ports, and even tried to boot it to recovery. Alas nothing worked. The device is dead.
After looking in different forums I saw this post about bricked cx-919 and possible solutions:

And since I had nothing to lose I've decided to give it a try.
Alas something went wrong yet again! As I opened my cx-919 I've noticed something is different in my cx-919.




First thing that was different- was that I had a thermal cover over the chips.



And since I did not saw any visible NAND chip I figured it must be under the cover.
So I removed the cover, and still couldn't find the Chip I'm looking for.


Maybe it's in the back I thought, but no
.

I hope one of you can maybe rise to the challenge, and help me find a way to make this device recognizable again by my computer.

So I kept on trying to fix the device, But still with no successes.
Since my device is built quit differently from other devices and uses different chips set, I figured I will try and understand what the different chips does.
Maybe by that I could find out which one is the nand chip. and try to short its 7-8 legs or 5-6 legs and get it to MASK ROM mode.
like the tutorial in this link http://freaktab.com/forum/tv-player-...ROM-mode-quot=

so the small one at the bottom (RTL87) as far as i can understand is the Ethernet controller, by real take.
the one in the middle is SK hynix this is a ddr-3 chip.
that only leaves me with the rockchip RK3128 chip to be the nand chip.
now all i have to do is figuring out if there are any legs i can short together like 7-8 in the micron chip in order to get this device in MaskRom mode.
Then i need to understand how to short them- since these chip's legs are underneath the chip and not on its side.

Nice set of links above, good to know there is a chance if something like this happens.
I do see your dilemma, the NAND pins are not visible, I don't have the needed electronics knowledge to help.

My CX919 suddenly decided to not produce a hdmi signal so I flashed it with NeoMode 3.1 yesterday. Flashed and works normally.
I *almost* used the ROM you linked above, even downloaded and unzipped it.

Hello, I also got the exact same device, tried many firmware none came. You solved the problem with the device?
