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

Step 1
Extract your stock kernel

1. Download and extract the tools to C:\RK3XXX\ (create new folder, DO NOT USE BLANK on any of folder name you created)
2. Open DriverInstaller.exe to install the driver required
3. Open Start.exe file as administrator
4. Click “Select Img..” and select your stock rom above
5. Click “Extract”
6. Wait until it finished
7. Close the Rk3xxx firmware tools
8. Your kernel was in C:\RK3XXX\temp\Android\Image\ as “kernel.img” file.
9. Copy the your kernel.img to C:\RK3XXX\patch\ (create new folder)
10. Step 1 done

Step 2
Patch and Overclock your kernel

1. Download and install Active Perl
2. Go to https://github.com/phjanderson/rkpatchomatic from your fav browser
3. Click “Download Zip” button on the right side of the page to download all the script. You will find rkpatchomatic-master.zip
4. Extract the zip and copy “overclockomatic3188” and “vsyncfixomatic” files on to C:\RK3XXX\patch\
5. Fired up your command prompt by using combination of win key+”r” on your keyboard. Write “cmd” and hit enter.
6. Navigate to C:\RK3XXX\patch\ by using this command:
   • C:
   • cd\
   • cd RK3XXX\patch
7. Patch your kernel by using this command:

   • perl vsyncfixomatic kernel.img

   • your patched kernel will be saved by the name of kernel_vsfsam.img
8. Overclock your patched kernel by using this command:

   • perl overclockomatic3188 kernel_vsfsam.img

   • select the CPU table (as for me table number 6)
   • select the GPU table (as for me table number 7)
   • select the DDR table (as for me table number 8)
9. It will creating over 40 different kernel configuration of CPU, GPU and DDR clock.
10. Step 2 done

Step 3
Flash custom rom and kernel

1. Download Finless 1.6b from the link above and extract it somewhere
2. Go to folder RKDevelopTool_v1.37 and run as administrator RKAndroidTool.exe
3. Replace the original finless rom kernel.img with one the patched and OC kernel on C:\RK3XXX\patch\ (i choose kernel_vsfsam_cpustock_gpu798h_ddr800.img. the CPU clock is stock but i overclocked the GPU (for graphic) and the RAM)
4. Hold the Fn button on your android stick while put in the usb cable to the computer
5. Make sure the tool shows “Found RKAndroid Loader Rock Usb”
6. Click “Erase NAND (IDB)” button
7. Click “Flash ROM” button
8. Step 3 Done

DONE!! Enjoy your clean and fast Finless ROM with working Wifi and Bluetooth and the HD Movies playback was very smooth even my Galaxy Note 2 LTE was no match against it (I’m seroius!). The Antutu scored 20600

ENJOY YOUR BT919 STICK!!!

here is all my modified, patched and OC kernel:
from baidu --> http://pan.baidu.com/s/15WL16
or
from mediafire --> https://www.mediafire.com/folder/1i0...20kernel%20mod

[delicacy]

Finally, i get a combination of custom ROM and kernel that working for my android stick BT919 (it’s what they called it) from Bluetimes. I bought it here.

Thank you!! Can you please provide a download link to your Kernel?

[ProvenSolutions]

It works great but...

Zetzzzzz,

It works great thnx a lot for your effort, but I still have issues with some dutch apps (rtl xl and npo) that provide streaming video. NPO flows smoothly the first 15 minutes and after that it needs constant buffering and the RTL XL app stops after just a few minutes. Do you know what might cause this?

Regards,
Martin

SOrry, but i dont have experiance about that Martin..
have you tried my methode to modify your kernel? after that just flash the modified kernel over your stock rom

[Max One]

Zetzzzzzz

Can u tell me pls, which kernel are u using to get that score over 20600 antutu points?

[pursch]

Thank you zetzzzz for the howto! Screen flickering is gone, bt is working fine. But Wifi seems to drop connection, this still needs someone investigation. Router is a Fritz.Box 7390, WLAN bandwidth is good at 65MBit/s.
Antutu benchmark is about 16000 (stock CPU frequency, oc GPU and RAM, same setting as zetzzzz).

[|<roni>|]

before i do this, could you point me in the right direction for making a exact backup of the stick as it is like all apps and everything as they are, so i can flash right back if anything goes wrong

to backup all apps and settings you can use Titanium Backup from the Play Store as mentioned here:

Check out this posting;

http://www.freaktab.com/showthread.php?7509-flash_image-Binary-Other-way-to-dump-your-stock-or-actual-rom-or-flash-partitions-from-android-No-PC-needed-For-rockchip

You can make the dumps right from your device. just be sure to back them up to a SD card or your computer before flashing you device, 'just in case'

Where titanium backup backs up your apps(ans system apps)(and their data), this would make a copy of your file system.

Heating -&gt; flickering on 1080p

Hi there,

thanks for the good work.
Until now this firmware gives me the best result on my CX-919 II.

However it still starts flashing after a few minutes.
It does not need to play some video for it.
Just opening the main screen reproduces this.

I opened the device and it appeared that one chip in partical was quite hot.
It is the Active 8846QM CD355 chip.
This chip takes care of the power supply.

My outlet adapter supplies 2A 10W. Will increasing this to a 3A 15W fix this problem?

As it starts after a few minutes I suspect a heating problem.

It only reproduces when 1080p is selected.

Regards, Jeroen

thanks for both replies, will be trying this sometime this week, hopefully tomorrow.
out of curiosity do you still need to use mx player to play 1080p videos through xbmc?

[thehoovie]

these are stock kernels at 720 - i tried xbmc player on 1080 files and no luck

These are 720 output stock kernels. I tried playing 1080 video files and they play fine with MXPlayer or QQPlayer, but not XBMC player.

I really want 1080 display but any 1080 kernels I found(that boot) either A)have no WIFI/BT or B)have WiFi/BT but flickering screen.

if you have 1080 kernel with Wifi/BT work still having flickering screen maybe you should try patch that kernel using my method above.

[thehoovie]

already patched
