[MOD] Build.Prop Tweaks

I’ve been scouring XDA and the net for some ways to make our phones a little bit better. What I have found is that you can alter your Build.Prop to work to your advantage.

Did you know that if there is an app exclusive to the Droid X and only works for the Droid X (not withstanding hardware issues), we can change our Build.Prop from Milestone XT720 to Droid X (whatever that model number is) and get into the market and download it?

There also other “tweaks” to you Build.Prop that are beneficial in many other ways, Data strength, Video and Camera resolution, GPS lock, Power saves,…

The below is what I have been able to find, save and test for most of our builds on the Milestone XT720, but first…

Choice is something that has been fought for, relinquished, dreamt of and lost. Here in XDA we have a choice to either use on not to use. This is YOUR choice. If YOU decide to use these tweaks, any problems that arise are YOUR responsibility. Now that is out of the way, here you are.

Oh and one other thing:::::::::::Make a backup of at the very least your /system because if something goes awry while editing the Build.Prop, all you have to do is restore your /system, since that is where the Build.Prop is located.

**XT720 Users->I have not tested these on any of the MIUI builds or Fjfalcon's CM7 release (per Sebastiman -all tweaks but camera work on Fjfalcon's CM7).**
Per Fjfalcon some of these are NOT working on [ROM][KANG][2012.01.30] CyanogenMod 7.2.0 RC0 Milestone XT720


If any Devs want to use these, that is cool. Just make sure you put in your OP that they are already on there so no one duplicates them on their Build.Prop.

I presume most of us are using Root Explorer or something extremely similar. You just need to have Root access and able to edit the Build.Prop text. I user Root Explore so that is what these are based off.

1, Open "Root Explorer" and click the R/W
2, Go to /system/build.prop.
3, Long-presson Build.Prop and you’ll see a pop up.
4, Text Editor.
5, Type in those few line of words below into the last line of the text then save.
6. Reboot twice

Data Tweaks Increase download/upload/3G speeds

ro.ril.gprsclass=10
ro.ril.hep=1
ro.ril.enable.dtm=0
ro.ril.hsdpa.category=8 (or 10,12,14) Still looking for more of these though.
ro.ril.enable.a53=1
ro.ril.enable.3g.prefix=1
ro.ril.htcmaskw1.bitmask=4294967295
ro.ril.htcmaskw1=14449

net.tcp.buffersize.gprs=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.edge=4096,87380,256960,4096,16384,256960

For some reason XDA won't let me take out the spaces between 4096, 16384. I have edited it twice and it still shows up with the spaces on OP. Should read 4096,16384 for all 5 (default, wifi, umts, gprs and edge) with no space between 6,1 or 16384

Change/Edit log:

11/4/11:::
1-Per peshovec qemu.sf.lcd_density::: if that is different from the default 240 or from 160, chances that some application from the market will be reported as incompatible with your device (web market), or dosen't show in the market (phone) are great.
So use what you want, but when you want to be sure, that you see all the applications, change temporary to 240 or 160

2-Per Sebastiman all tweaks work on Fjfalcon's CM7 except camera ones (caused boot loop)

11/9/11:::
Took out spaces in net.tcp.buffersize as was a copy/paste issue from Word.doc to XDA.

1/6/12:::
Took out some of the Motorola XT720 ROM specific verbiage as this is being view by way more people/devices than the XT

2/1/12:::
Noted the some of these are not working on [ROM][KANG][2012.01.30] CyanogenMod 7.2.0 RC0 Milestone XT720

I wonder if there are reversals?

Just make sure you have a back up of /system because that is where the build.prop "lives". Also I have found that when I edit them, it creates a .bak backup, but you can never fail restoring a nandroid of just the /system.


As a side note, AA1973 gave the "stock" Build.Pro for the MIUI and 3rdstring (of course) uploaded a .zip with damn near the rest of them here http://xdaforums.com/showthread.php?t=1327141

Plus is you adjust a value, wirte down what the original was and if new doesn't work for you, jsut pust back in the original. This way you shoudl only have to restore /system nandroid is something screws up majorly.

That's cool. I know that when I was on Kahl's V4, mine was at 48 and never had a problem with it. Think the intervals are 24, 32, 48, 64

Edited OP with that.

Try it out but ok to skip too. I have read that this might have something to to with the LED notifications that we have all been looking for. Will keep looking into this weekend for that part.

Don't forget you have to reboot twice.

qemu.sf.lcd_density (here there is typo for the keyboard it should be qemu.sf.lcd_density, instead of ro.sf.lcd_density).

I will edit OP later on when I get to PC. Thanks for re-checking the lcd.density issue too

Excellent. Will update OP and start working on fixing the camera tweaks.

Hey Wood, do I type in all these commands? save after the first set? Or what do I do...?

Click to expand...

You can type them all in at the same time, but when I did it I did ti in pieces to make sure each one was taking effect and if I got looped was able to determine which one caused it problem (like typo ro something like that).

LibertyMonger said:

You see any typo's in here? The space between 163 84,? Is that correct?

***also have you tested these on Bravo?


***I got all the tweaks saved but I think I better leave well enough alone lol. Bravo is almost perfect as is everything is running great. What do you think Brian? Should I try these?

Click to expand...

Click to collapse

I'll fix that in the OP. No spaces between 163 84. Should be 16384. XDA must have remarginalized them when I put it in here. I copied them from a WORD.doc when I was compiling.

I tested the data tweaks and a few of the system tweaks on Bravo and they worked fine. But if you have everything working fine for you, I would suggest either leaving it alone or bit-piece them in there. Don't want the lightning rod effect like you had in HM's ROM.

p.s. - Sorry I didn't respond sooner, I was mostly off-line this weekend and took a few extra days off. Kind of a brain recharge thing.

anybody have descriptions of these?
A lot of these are smaller / larger than what the "change to" value is...not sure how they're going to affect things, such as--
1. why are there 6 numbers for the tcp buffer sizes
2. I don't notice any performance diff modifying the max_events_per_sec
3. Proximity Delay-- is that in ms? If I think my prox delay is "too long" when I take phone away from face, I should make this smaller, right? How small is OK?

What ROM are you running? That would help me answer your questions a bit more clearly.
