Edits and Tweaks: Build prop, bools.xml

js2892 · Apr 29, 2013

build.prop edits are very easy and useful, they can be applied on stock rom/kernel, i have compiled this from various sources!
For ICS, most of these will be useless

Locate build.prop
got to system/ and find build.prop

Edit with notepad++. Save and overwrite previous file, then change permissions to rw,r,r!
Change the tweaks already present and add new at the end of file!

Change android name and version
ro.build.display.id=Your ROM name
ro.build.version.release=2.3.6 (Android version number)

Decrease boot time
debug.sf.nobootanimation=1 (Disables bootanimation)
ro.config.hw_quickpoweron=true
persist.sys.shutdown.mode=hibernate
dev.bootcomplete=0

Power saving
ro.ril.power_collapse=1
pm.sleep_mode=1
wifi.supplicant_scan_interval=120 (sets wifi scanning interval, can be increased or decreased)
ro.mot.eri.losalert.delay=1000 (might break tethering)

3G Tweaks
ro.ril.hsxpa=2
ro.ril.gprsclass=10
ro.ril.hsdpa.category=10

ro.ril.enable.a53=1
ro.ril.enable.3g.prefix=1
ro.ril.hep=1
ro.ril.enable.dtm=1
ro.rill.enable.a53=1

Telephony/ring Tweaks
ro.telephony.call_ring.delay=0
ring.delay=0

Proximity (Disable blackscreen issue after call)
mot.proximity.delay=0
ro.lge.proximity.delay=25

Smooth Scrolling
windowsmgr.max_events_per_sec=84(This value is experimental)
ro.max.fling_velocity=12000
ro.min.fling_velocity=8000

Disables error reports
profiler.force_disable_err_rpt=1
profiler.force_disable_ulog=1

Force home launcher into memory(use light launchers only)
ro.HOME_APP_ADJ = 1

Render UI with GPU
debug.sf.hw = 1

Disable logcat
logcat.live=disable

dalvik.vm.heapsize = 64m
Note: This value is different for different phones, the value can larger(128m) with larger RAM device, use accordingly!

ro.config.hwfeature_wakeupkey=0

Change LCD density
ro.sf.lcd_density=160

Allows purging of assets to free up RAM
persist.sys.purgeable_assets=1

Locate bools.xml

1. Decompile framework-res.apk
2. Go to res/values and find bools.xml

There are a lot of threads on the subject, but would Google any before using them as some work better on other devices or they don't do anything at all.

Yes, scrolling speed, vm heapsize, lcd density etc are different for devices!

I once tried to change my phones model via build prop using the same method you wrote up and my phone bootlooped.
Im on n2 sgh-i317.
I fixed it but was wondering what I could have done wrong. Im slowly inching towords getting my feet wet in learning aboutvrom making. Nice thread btw.

u mean the android version or the phone name...
well, irrespective of that, it's quite weird that build.prop edit lead to bootloop...I've edited these things many times and worked normally for me..
if you know how to read logcat etc, u can get a logcat try that to point out the reason for the same!

koffeeluver · Jun 10, 2013

Before posting things like this, I highly recommend reading this and this just so you know what works and what does nothing (hint: a lot of the tweaks don't work)

Well, i've read this earlier but forgot to mention about this in OP (i'm still on a GB phone

)

Thanks for pointing out, i've edited the OP.
For GB, i've tested them and they work like a charm( with exceptions for some phones).
