**Edit Please note that the original title of this thread said ICS 4.0.x, it should be ICS 4.0.4 (as it is now) - This build.prop is specifically made for 4.0.4 - this is very important as keys such as: ro.build.version.release=4.0.4 ro.build.id=IMM76L if you know what you are doing you can make minor alterations to fit your build and it will work, but you need to research and do this at your own risk if you aren't using 4.0.4 (hint: ICS 4.0.3 is IML74k) **
I've been working on getting my A100 to smoking speed / performance and with my custom build.prop for ICS in combination with ezTerry's custom kernel, I think I have achieved the goal! PLUS you *should* get all apps that the A500 gets in the Play Store, AND the responsiveness of the tablet is just lightening fast.
Yea Yea, So why another build.prop on xda? Well I was looking through the forums and noticed that there isn't much posted for ICS, there are HC tweaks, but the ones that ARE posted for ICS seem to fail.. I am confident that this build.prop will work as long as the person installing reads the instructions and information in this post thoroughly
I am using the ezTerry kernel overclocked to 1.5 using the ondemand governor. Before the build.prop, my AnTuTu Benchmark score was 6998, after the build.prop I get 7494, Both scores with ezTerry kernel and cm9 ; With stock kernel and stock rom score was <5900. So, that's just a benchmark.. -NO - The main thing is - you can actually feel the difference, and it is easily noticeable, so it's not just a benchmark thing! Here is what this build.prop does:
*A500 Market/Play Store compatibility
*Home Screen stored in Memory
*WiFi Data rates increased
*WiFi Scan rate decreased to preserve battery
*Media and Image Quality increased
*Disable verbose kernel logging (consumes less memory/battery)
*HW Acceleration prioritized
*Increased Window Manager / GUI events per second
...Overall Performance is definitely noticeable!
How to install:
*You must have root, and you must mount /System rw (use Root Explorer or similar tool)
*Rename the attached file to: build.prop
*Move the existing /System/build.prop to /System/build.prop.bak
*Move the new file to /System/build.prop
*Reboot to recovery - Wipe Cache - Wipe Dalvik - Reboot System <<Important!! It won't work if you don't do this step!
*Wait for System to upgrade applications and Start to Home Screen. (initial boot takes a while, don't worry after this it wont)
*Reboot again.. Enjoy the performance
** This has been tested with only 4.0.4 CM 9-20120708 A100 so far (see http://forum.xda-developers.com/show....php?t=1597102
) testers please report results!**
**Note it is very important to know that this build.prop isn't the only thing boosting the performance of my A100 - ezTerry's Kernel OC'd @ 1.5ghz plays a big part in it too! You can find the kernel and instructions for flashing it here: http://forum.xda-developers.com/show....php?t=1703683
It is also important that you know that after you use this build.prop your device will register with all apps as an A500 Iconia and not a A100 so if that is an issue with some app you use then please take this into consideration. I will edit this post soon with a build.prop that enables the performance options and keeps the A100 recognized as an A100. I'm sure there will be people who want that also.
*More to come:
* I plan to clone the sources used in ezTerry's kernel and slightly modifying his config in an attempt to patch with CK/PF patches for mainline. I'd like to see the performance when using Brain F**k Scheduler (BFS) in combination with BFQ IO scheduler. These patches also have other features like l7, LinuxIMQ, which may be fun to play with on Android with networking apps (if they will even compile with arm toolchain) I'll keep everyone informed on my progress with this, but I'm saving that work for a rainy day.
Enjoy your A100
