build.prop

---

Here's a modified build.prop Ive tested on my Thrill. It includes a lot of the tweaks posted in various links but already packed into a build.prop.
I have tested to make sure that this build.prop will NOT break your phone. Im running this build.prop on my Thrill with no issues what so ever. Actual improvements from these tweaks are up to you to test. I make no claims to their actual effectiveness.

To use this just put it on your sdcard and rename it to build.prop (its currently just a .txt file for upload purposes). Then paste it into your /system partition using a root file explorer such as root explorer or estrongs.

Here's a list of the actual changes and what they are supposed to do:

ro.HOME_APP_ADJ=1 Keep home launcher (any) persistant in memory
ro.telephony.call_ring.delay=0 make phone ring faster when dialing out
ro.lge.proximity.delay=25 disable blackscreen issue after call
mot.proximity.delay=25 same as above
windowsmgr.max_events_per_sec=150 Better scrolling speed
wifi.supplicant_scan_interval=250 increase time between wifi scanning to save battery
pm.sleep_mode=1 save battery?
ro.ril.disable.power.collapse=0 save battery?
debug.performance.tuning=1 increase touch responsiveness
video.accelerate.hw=1 goes with above mod
debug.sf.hw=1 render ui with gpu (potentially taking some load off cpu?
ro.media.enc.jpeg.quality=100 increase jpeg quality to max
persist.adb.notify=0 removes the debugging mode notification from status bar

The following are all meant to improve 3G speeds
ro.ril.hsxpa=2
ro.ril.gprsclass=10
ro.ril.hep=1
ro.ril.enable.dtm=1
ro.ril.hsdpa.category=10
ro.ril.enable.a53=1
ro.ril.enable.3g.prefix=1
ro.ril.htcmaskw1.bitmask=4294967295
ro.ril.htcmaskw1=14449
ro.ril.hsupa.category=5

Net speed tweaks
net.tcp.buffersize.default=4096,87380,256960,4096, 16384,256960
net.tcp.buffersize.wifi=4096,87380,256960,4096,163 84,256960
net.tcp.buffersize.umts=4096,87380,256960,4096,163 84,256960
net.tcp.buffersize.gprs=4096,87380,256960,4096,163 84,256960
net.tcp.buffersize.edge=4096,87380,256960,4096,163 84,256960

Those are just the ones I know will NOT brick/bootloop your phone. Feel free to remove whatever you dont want to use. All additions are at the end of the file. So all you rom devs feel free to include them in your roms. If anybody has any more they've tested let me know so I can add them. And ill update the build.prop as I test more tweaks.

EDIT: Included the original build.prop file (original_build.txt). Just rename it to build.prop and stick it on the /system parition.

Well the thrill can do 4g it is just on att's crappy network which means we get 3G+ not true 4G. Att is too expensive, has horrible cust service and an even crappier network. However i live in att corporate heaven so where I live coverage and speed is top notch, when I travel though I see why everyone complains so much about them.

Okay, so I'm at the point I'm looking at it on root file explorer. As per your instructions, do I just copy and paste it the entire file onto my system partition? Or do I open it in a text editor and erase what I don't want? I ask because you mentioned using what you want out of it. And have you noticed improvements by using it?

Just open the file and delete the lines you dont want. Then Rename the file to build.prop and then copy/paste to to your /system partition.

The network tweaks made no difference in speed for me. The persistant home was an improvement. The rest its hard to tell of it's placebo or not without some way to test. The problem is I didn't have the phone long enough before making the tweaks to get a good enough feel for it to tell the difference definitely no negatives to those tweaks though.

Okay so I've edited out and kept what I want and changed it to a build.prop. I'm using root explorer. I don't see a /system. I see a system. But when I go to paste it in there, it says I already have a build.prop and it will replace. Obviously I don't want to screw anything up.

Looking through my build.prop that's in the root, it doesn't have anything listed like what's on the build.prop (txt) that I downloaded. Can I paste it into there or is that a terrible idea?

This makes me wish I had a couple of phones like this just to mess and tinker with.

Okay, so I'm looking in the build.prop folder and I don't see any listings for the ro.ril files. I downloaded prop editor and can't find them there either.

The build.txt file I posted is meant to replace your original build.prop file completely. Everything from your original build.prop should be in the new file, but not vice versa. So once you renamed it you can just delete the old build.prop and paste in the new one and reboot the phone. If it gets stuck at the boot screen (the att screen after the LG screen) then you will probably need to pull the battery and boot into CWM recovery and restore a backup. No harm no foul. But like I said earlier, ive actually tested this build.prop on my phone and it boots fine for me every time. So you should have any issues.

Of course all of this should be done after doing a back up, just in case. Better safe than sorry. As long as you have CWM installed and have made a backup you wont do any damage with the build.prop that you cant reverse with a nandroid restore.

Done and rebooted back just fine. Thanks given!

I'm liking this phone but should I choose to return it, when they send the phone back to AT&T and clean it up to sell it as a refurb, will they be able to tell the prop.build has been altered?
