Latest stock rom + rkbatchtool + driver:

http://www.sendspace.com/pro/dl/7bzbci

the stock rom was good with Antutu 4 score of 18600 but sadly still having issue with running HD movies as it’s still has lag or stuttering.I tried flashing neomode ROM v1.9a and many of kernel mod by others, but the wifi and bluetooth stop working. I know the problem lies on the BT919’s kernel and no one seems provide the correct kernel for this awesome android stick.

So..i wandering to many thread on this forum and finally making my own kernel mod. I flash it with Finless 1.6b (i tried with neomode ROM but didn’t work). So this is how i get it done (**use it with your own risk**):

Tools:

1. Windows OS (i tried on Vista 32bit and Win 8 64bit)

2. Rk3xxx firmware tools v. 4.0.33.00 --> extract your kernel from stock rom. Thanks to mo123
