do you try on your computer with usb-usb cable ?

[dangchui]

Yes i have try with usb male male cable and it s no detect and light blue in front is off

[manu_manu4]

you probably need to shortcut 2 pins in your nand to enter in maskrom mode.
i need a better picture of nand and wifi chipset. For know firmware to restore and to show you pin to shortcut.
part in red on your picture.

Is this your board?

I have the same board "bricked", because I had a 6.0.1 firmware on it that had problems with Google accounts, so I flashed it with a wrong firmware.

I've tried almost every rk3229 rom on the net and the only one that works is one from MK809IV: http://freaktab.com/forum/tv-player-...-unbrick/page3

In the link there's a pic of the 7-8 pins you have to short to get recognize your board into rk android tool.

Why did you choose that specific firmware you linked to flash your box?

I'm looking for a right firmware for my board (that is the same as yours) from 3 months and no one is the right one... :-(

hello DS-1 You must see just near the nand curcuit what is the mark of your chipset wifi it s important for take a good firmware for you

My wifi is 6051p, i've tried almost all 6051p firmware for RK3299, but no one works for my board.
always tells "download idb fail" :-(

What firmware are you using for it? What wifi have you onboard?

[dangchui]

I have blu low light led. When connected to USB the pc recognizes it as MASKROM without doing any pin jumper, so I believe it's broken.

[dangchui]

no if it s connected with out any pin jumper is ok just bricked i have found this firmware for you https://yadi.sk/d/veU_J9Td3LjxFR that s wirte for wifichip 6051

It's hard to unbrick because it goes in MASKROM mode WITHOUT doing jumpers and tells "download idb fail" at any flashing. It didn't do it some days ago. Maybe the flash memory is gone.

I already tried the firmware you posted (it was a month ago), it didn't worked.
