I dare not to try it because i don't know will it brick my devices or not.....

You won't get the Lollipop experience because it runs JB kernels, too old.
It hasn't been fully developed by Rockchip, so have to wait a few months.

Thanks for reply~
What you mean by “Lollipop experience"? Some lollipop feature won't work?

You will get all the Lollipop apps and user interface, but hundreds of fixes and improvements to drivers, stability, video playback, speed etc. won't be there that are included in the kernel. Latest RK3288 run 3.10 kernels, RK3188 still run 3.0.36 kernels. Even KitKat that run 3.0.36 kernel has more than 200 changes compared to 3.0.36 Jellybean kernel.

WOW! i learned something today , Thanks~
So rockchip is currently developing a 3.4.0 kernel for RK3188 ?

No, a 3.10.37 or something kernel
Here is RK3288 Chromebook kernel 3.14.0, go back until you find 3.0.36 kernel, it will be several hundred/thousand pages of changes.

https://github.com/rkchrome/kernel/commits/master

They are more interested in RK3288 devices, so RK3188 support is going to be limited.

So this is something I am interested in, because my device has two firmware available, 4.2.2 and 4.4.2 but the 4.4.2 has the same kernel (3.0.36) as the 4.2.2. Am I just as well off using the 4.2.2 aside from the interface? And if I use the 4.4.2 will I have difficulties rooting it because of the kernel version?

The 4.4.2 has over 200 improvements and better video playback & fullscreen apps even if it's the same kernel version. Rooting is the same regardless of Android version.

Mo,
I have ran Lollipop (WOW Nice) with the JB and KK kernels on my radxa, with really no noticeable difference. From what I understand is that the 3.0* are basically 32 bit and usually involve a nand storage which can't recognize the higher chip functions without a u-boot from a MMC source, which I haven't heard anyone solving yet. Have got my firefly on the way with an emmc nand storage.

Witch kernel and box are you using?

Just tried the Lollipop...found some strange things

With the 720P kernel provided (RK31 Kernel 3036 Box X7 Minix) , Wifi is working but SystemUI keep crashing

With JB 720P kernel, SystemUI keep crashing and Wifi doesn't works.

With JB 1080P kernel, SystemUI works but Wifi is not working.

I am using the Radxa RKCrew JB kernel (Nice, Tweaked). Are you using the rkcrewtablet build, if so, did you use the parameter fix if needed and the CWM 160DPI.zip fix (system.mui has occurred for me w/o this fix). Wifi is rt8723, look for Fix for yours if another.

Thanks! wifi works and system UI won't crash anymore!
