[Android Stick & Console RockChip based Computers] kidpollos:
Hello everyone .... I state that I have read and reread all of the pages that they could solve my problem but to no avail ...

I purchased from aliexpress this MK809III rockchip RK3188 ( Rockchips 3188 Quad-Core 1.8GHz Android 4.2 wifi chipset AP6210 ) ....

From the beginning I had just purchased wifi reception problems , despite the router was in the same room miniProfile and all other devices ( ipad iphone smart samsung notebook etc. . ) Also had maximum reception on the top floor ... I tried various configurations ( prolinga hdmi cable , power supply , usb etc. . ) but the reception was always unstable and I could not even watch a video on youtube. After finding this forum and trawled the various discussions , as others had had problems with reception, I tried to open the " box " , I found a black wire from the " matherboard " was going to end on a sticker attached to the antenna body in plastic ... so I disconnected the antenna adhesive and tramita slot uSB connectivity I took her outside, and maximum receive perfect result ... finally everything worked perfectly .... I install some apps (radio, tv, youtube and a few other essentials such as suggested in some threads ) and everything runs smoothly ... the other day out of the blue goes off and there was more towards re-starting .... black screen .... I click the reset button for a few seconds , reconnect but nothing .... then decided to embark on the path of the flash ....

Problem connecting to pc .... I click the reset button for 5 seconds , I connect the usb port to pc release the button but nothing, is not recognized .... no hardware connected .... after a while it occurs to me to try to change the cable ... I take a mobile phone with a cable microusb , I connect it to the appropriate port , and I can do it recognize and intsallar and drivers ... Now instead of trying to connect the TV to see if the problem was the cable, continuous and start to flash effetture procedures , discharge all the tools and various firmware for rk3188 chip , these are all the ones I tried to install :

4.2_mk809III_finless1.5 (anche questo dovrebbe essere l'originale)

neotvhybrid

some are in ISO format and I tried to install them with the tools Rockchip Batch Tool v1.7 , others unpack once gave me several folders and installavo with the tools present in each package RKAndroidTool ( that installed in automatic loader kernel parameter and so on. ..)

a few times I was able to install them, but once connected to the TV, or black screen or logo fixed ( w2comp example ) and then nothing for half an hour, other iso seemed to me an android with a gear but all blocked , other times certain written reser etc but could not load any folder) and then try and try again but now I can not charge us anything ( the only one that gives me the neotvhybrid is ok but always black screen ) .. the other I make the flash ( even with idb ERASE OR RESTORE but at the end of the operation the message DOWNLOAD FAILED ERROR - ERROR RUN FAILED ......

Now I do not know what to do anymore ... I seem to have tried everything ....

I'm going to attempt but I can not come again ... but at least the original image should charge ...

could you give me a hand???

I tried to flash the rom using a different pc "virgin" on which I installed xp rom but any attempts to install, the tool performs the following tasks:

erase of the 'IDB,

ok test device,

start file download,

start to flash download,

writing data to flash (460976) written (460976),

Check start date download,

checking download date, size (460975) K, Checked (4) K

download error failed file

error failed run

then the only one that I can install it t-r42-wasser-1.2, correct writing, connect it to the TV I apapre a gray screen with a central gear with a hat on MK809III, I can select Rebot system, install zip from sdcard, install from sideload, qipe ... advanced backup ...,,, but I can only reboot, which when executed by me black screen continues ....

I found on a foreign forum that some users had the same problem and solved it this way:

using the flashtool ( RKDevelopTool_v1.37 ) , do ERASE IDB , then deselect check out PARAMETER then run the flash button ( RUN) ... after that deselect everything and run the flash only PARAMETER ....

I tried it and finally I managed to do the flash ...

connected the device to the TV, waited more than 15 minutes and at the end of the boot is successful uinico problem ... I can not turn on wifi, or better still active but does not find anything and after a few seconds turns off the bluetooth keyboard works ... properly ...

the rom is installed " neotvcr_mk809_3_ug007b_20130615 ."

I tried to install the finless even with this method always gives me error ....

boh ...

one thing I've noticed is that whereas before when I connected the device to the PC Estates reset after a few seconds she recognized him , now I have to hold down the reset button for almost a minute before the device is recognized by your PC ....
