MK809IV RK3229. Bricked. How to unbrick??

[GeraStrummer]

MY DEVICE: Mini Pc Android 5.1 Smart Tv 4k Quadcore 16gb 2gb Ram Tv Box.

mk809IV RK3229

Hi. i flash the firmware, everything went cool.
But when i connect it to the power, the blue lights turns on but lighter than before.
nothing appears on screen. try to enter in recovery (pushing the reset button and plug in the power) but nothing happened.

i was trying to do a downgrade beaceuse my 5.1.1 android version wasnt working well.

any ideas how to revive my device??

its the black dongle with the red antenna. some pics of the inner device

EDITED 21-01
I found the way to flash it, shot the 7 and 8 pin of the nand.
batchtool recongnizes it, but it appears in blue.
im looking now for the firmware. try a few and the stick doesnt work

anyone has the firmware for this crazy litle stick??

[GeraStrummer]

yes. i flashed it via batchtool. it recognizes my tv stick on blue. flash it all but when connecting via HDMI, nothing happens. also the led is less brighter than the first times i used it.

You need flash it wth BatchTool v1.8.

[GeraStrummer]

well, i try it.
load firmware on batchtool 1.8. connect the stick. the software gives me the blue square. click on restore. finishes, saying SUCCESS 1 FAIL 0 on green background.
but then, connect it to tv via hdmi, and gets no signal from tv.

once you flash it with batch tool, thats all. or im i missing a step in the proccess???

Hi GeraStrummer ,

No it sound correct , try to reconnect the HDMI Cable , but is it really RK3229 not a RK3188 , if it is really a RK3229 try a RK3229 TVBOX Rom maybe Mos Roms ???

Really, my stick is the MK806III, not MK809IV.
Your procedure looks correct. Sorry, I don't have the firmware for the MK809IV RK3229.

Hi, sorry for my bad understanding english but what do you mean with "shot" 7 and 8 pin? Could you pleasee explain what i have to do with those two pins and afterwards i also have a bricked from a false rom MX4 (probably a V88, rk3229 box) flashed superceleron for mxq... And bricked.

Thank you anyway

Hi, to unbrick the device you need short circuit the nand, for make you have to connect the pins 7 and 8 or 6 and 7.
Look that video

Hi,
have anyone maybe found a working firmware for this freaking stick? I have tired:
CG_ROM_MXQ-4K_20160515_STOCK20160412
CX-R9-RTL8723bs-20160223-update
MXQ-4K_ota_20160308
update_rk3229_mk809iv_rt8189_20161220(韩国)_r2
update_rk3229_mk809iv_rt8189_20170215(韩国)_r1
update_rk3229_MK809IVPRO_rtl8723bs_20160921
update_rk3229_MK809IVPRO_rtl8723bs_20160926(KloudS ign)
update_rk3229_MK809IVPRO_rtl8723bs_rupa_20170110
update1.0.0

None would boot properly... Most are flashed ok, but then device will not boot (led is on with half bright and nothing happens), some would fail during flash.
I didn't save the original image (duh!), but it was useless anyway since wifi gave net_timeout regardless of range...

Anyone has a working ROM for this box please?
