MODS Description

Code:

<br />
[U]Build.Prop edits[/U]<br />
These are edits made to the build.prop that I have changed to increase performance, battery life, and data speeds.  <br />
<br />
[U]Cron[/U]<br />
Cron is a popular time based job scheduler on Unix/Linux, and is super useful as you can virtually run any command or script periodically at certain times or dates.<br />
---For this script I have cron erasing vm caches twice daily, at 2am and 2pm.<br />
<br />
[U]SD card speed increases[/U]<br />
--increases speed of sdcard reads<br />
[U]<br />
Sysctl tweaks[/U]<br />
Edits to the sysctl.conf file in /system/etc/ These tweaks are for performance to allow device to run better.<br />
<br />
[U]File System Speed increases[/U]<br />
Same as SD but for file systems<br />
<br />
[U]Swap(if device supports)[/U]<br />
Swap moves inactive processes into virtual memory, allowing the device to not become laggy or slow down.<br />
<br />
[U]Dirty Battery Calibration[/U]<br />
[B](Mod by Droid Th3ory)[/B]<br />
This mod sets the level when the phone is rebooted the first time after you run option 3. It sets the battery level reported by the OS and creates the battstats.bin file.  This in laymans terms means that it wipes the battstats.bin file for you and calibrates it to what the current battery level is and adjusts according to that, thus eliminating the need to actually manually wiping battstats.bin and calibrating it yourself. :)<br />

Powerboost Conservative CPU Governor Information:

From Kernel Documentation:
The CPUfreq governor "conservative", much like the "ondemand" governor, sets the CPU depending on the current usage. It differs in behaviour in that it gracefully increases and decreases the CPU speed rather than jumping to max speed the moment there is any load on the CPU. This behaviour is more suitable in a battery powered environment.

However, this gov is changed from your normal conservative governor. The changes are:
* Down Threshold changed to 40%--Steps down the CPU if usage is below 40%
*Ignore Nice Load is set to 1--ignore usage of not so important tasks
*Sampling rate changed to 160000--makes cpu change decision more frequent than default conservative
*Freq Step is set to 16-- CPU stepping will take place in 16% increments, thus allowing faster up-step of cpu levels, and quicker down-step of cpu levels=better battery life

The modifications are designed to increase battery life by allowing more emphasis on keeping cpu level down and allowing it to go back to min level quicker.

Mirror 1 (provided by iluvamk)

Here is a video installation guide done by DroidModderX. (Changed terminal emulator commands res is the same)

BIG thanks to him for this.

For those of you on an untested rom, all options are available to yu except for Option 2(unthrottle), and if you would like added support please sendthe services.jar file located in /system/framework/ to me via pm or email/gtalk: [email protected]

Current Bugs:
Mobile Network Settings will FC.
Battery Icon in Status Bar Disappears for some users(Only seen in MIUI-but top bar works)

Fixes:
My initial plan to include fixes will be along the method of patches to be flashed in cwr hopefully, with 2.0.1 including the first one and so on...once all bugs are fixed or the vast majority of them I will see if including an update script that will auto boot into cwr and flash the patch for you.

Code:

Does this support accurate battery on Droid X2? (97% or 52% rather than 10 or 20% increments)

I just noticed that one of the patches is the services.jar which is where the battery reporting function is, so the file it replaces, is that file modded for accurate battery? That's what I was wondering.

Also has anyone been able to flash this? I've downloaded twice and can't flash, keeps saying error status 0. Other zips flash just fine...

Decided to give this another go. Ran the script via adb. I'm mainly interested in the conservative governor.
I get errors though:

Code:

<br />
Installing Conservative Gov cp: can't create '/system/lib/modules/cpufreq_conser<br />
vative.ko': No such file or directory<br />
cp: can't create '/system/lib/modules/symsearch.ko': No such file or directory<br />
chmod: /system/lib/modules/symsearch.ko: No such file or directory<br />
chmod: /system/lib/modules/cpufreq_conservative.ko: No such file or directory<br />
Done<br />

So I created a folder called modules in /system/lib and that worked. So now it has the kernel modules in that folder, reboot, and checked the governor... no change. After a little investigating, looks like these modules are not at all compatible with our Droid X2.

Code:

<br />
# chmod 644 /system/lib/modules/cpufreq_conservative.ko<br />
chmod 644 /system/lib/modules/cpufreq_conservative.ko<br />
<br />
# chmod 644 /system/lib/modules/symsearch.ko<br />
chmod 644 /system/lib/modules/symsearch.ko<br />
<br />
# insmod /system/lib/modules/cpufreq_conservative.ko<br />
insmod /system/lib/modules/cpufreq_conservative.ko<br />
insmod: init_module '/system/lib/modules/cpufreq_conservative.ko' failed (Exec format error)<br />
<br />
# insmod /system/lib/modules/symsearch.ko<br />
insmod /system/lib/modules/symsearch.ko<br />
insmod: init_module '/system/lib/modules/symsearch.ko' failed (Exec format error)<br />

So then I thought, ok, well, I'll try the battery calibration thing, since I'm a bit annoyed at Motorola for releasing an update that has battery jumping.

Code:

<br />
# sh /sdcard/unthrottle/etc/init.d/91battcalibration<br />
sh /sdcard/unthrottle/etc/init.d/91battcalibration<br />
# /sys/class/power_supply/battery/batt_current: No such file or directory<br />
