R-Box Pro 3GB (q9377) bricked and recovery doesn't boot but I have access via serial port

[tinyrick]

I was trying to flash a custom logo on it and the colors were not correct and on my 6th or 7th attempt to flash a proper logo, suddenly I got a brick. Even the recovery mode doesn't boot (it used to work before).

Things I've already tried:
1. Tried putting a recovery image on the sdcard
2. Hold reset button during boot
3. Amlogic Burn Card Maker to prepare bootable sdcard
4. Tried flashing uboot on the sdcard using dd on Linux

I have a serial console and I have some logs saying that the device is rebooting. Logs can be viewed here - http://paste.fedoraproject.org/508391/

I read somewhere about shorting pins on the NAND and was wondering what this does exactly. What is a good tool to do this properly?

tinyrick Hi. I have the same problem although I wasn't tinkering with this the box. One day it was working, next day it's gone. Doesn't reboot, doesn't start. Doesn't enter recovery mode even though it was able to boot into recovery before. I bought it from Geekbuying probably 4-5 months ago, installed apps and was disappointed by its performance. So I orefer d to wait for a solid firmware update and and never used it. It's so disappointing.
i haven't tried with images yet as I have feeling that it won't work.
1. I did hundreds of resets while pressing the reset button with no success.
2. Tried a different HDMI port.
3. Different HDMI cable.
4. Leave it for a day or 2 then connect it back to power.
5. Checked the transformer's output voltage and it was fine at 5.2V
5. I bought a universal charger with 5V and 2500mAh
But nothing worked. Once I connect it to power the blue light shines (I think it's dimmed a little bit), but nothing happens afterwards.

its so disappointing as my only hope left was to try the Amlogic card maker and trying to boot from SD card.
Have you got any success?! Did you reset any hardware pins?!

my post in other topic:

Hi guys, sorry for my bad English, but I'll try to explain my problem.
My brick box while it was running, with application es file explorer and then tried restarting, and got into bootloop.
I logged into recovry and did a wipe cache and wipe data factory reset.
That's when my problems started ...
The box has not started, only the blue led. I did the Usb burning tool flash and by the card maker, but the process stops at 7%.
I already tried several firmware and also boot recovery.img on the sd card, but it shows that the internal memory is 0MB.
Help me!! I lost my box?
