I am gonna try this rom, as the kitkat rom flashed earlier caused out-of-the-blue restarts and other strange problems. Thanks allot.

I do hope pipo keeps updating their roms! Peferably to kitkat

Are there also custom kernels available? Overclocked and with different governors?

Tablet : PIPO M9-Max (as printed on back)
Adndroid: Ver- 4.1.1 (See Screenshot)

Hi Admin,

I am techie, PC's OS Guru, new to android world. Last nigh I was trying flash my pipo m9 from 4.1.1 to newer 4.4 Kitkat. Googled and found this fantastic forum & really dedicated people here, hats-up to all you folks.

STEP : (1) FLASH-ing my tablet

http://www.arctablet.com/blog/forum/pipo-max-m9/rom-pipo-m9-android-4-4-2-kitkat-custom-root-firmware-20140604/

Downloaded RKBatchTool, I tried to flash, but no success. It seems started good, but stuck at flashing yellow box, saying

"checking device started..."

which obviously never ended. Sooner, I discovered someone else in this forum had similar situation, and needed to Brick.

STEP: (2) BRICK-ing my tablet

http://www.arctablet.com/blog/forum/firmware-flashing-on-rockchip-based-devices/downgrading-android-44-firmware-to-android-43-earlier-rockchip-based-devices/

I then exactly followed this thread to brick my tablet, using Rockchip bootloader RK3188Loader(L)_V1.24.bin which worked for me. I was able to see what many described "Modus" mode.

STEP: (3) DOWNGRAD-ing : from PIPO Firmware Update -no success

http://www.pipo.cn/En/index.php?m=Product&a=show4&type=2&id=260

Tried all listed versions, but No success.

STEP: (4) DOWNGRAD-ing - from this forum - wow it worked.

http://www.arctablet.com/blog/forum/pipo-max-m9/rom-pipo-m9-custom-root-android-4-2-2-firmware-version-1-0-9-20131130/

Downloaded this adnroid 4.2.2 Jelly-Bean image, this worked for me with few issues. Huh.. spent whole night, but finally, I am happy, I can see my tab working pritty fast, Wifi Fast, interface is looking cool.

Dear admin, Here is my detailed observation about apps:

Account setup - good
Google PlayStore - good
Most gadgets - good
YouTube - Good
Antutu Bench.5 - Goog
DocToGo - Good
Facebook Apps - Oops, installed with error msg (OS not customized for
facebook apps)
Facebook Messenger - Downloading never completes at all, freezes.
Weather Widget is in Chinese language, cannot select city.

Overall, NOT usable, such a vasteful of efforts. Most humbly, if you had taken such a great pain for making this 4-2-2 firmware image, it might have been usable if you would have added some customization for most 
frequently used apps such as facebook, messenger, whatsapp etc.

I am going to flash again, searching for a better working version, any suggestion based on my above specs and finding will be highly appreciated..thanks.
