Simply STUNNING 5.4 tweaks for all

[metalspring]

I have discovered a number of different performance and battery enhancement tweaks throughout the forums here and I'm bringing all of them into one thread for easy access...I take no claims on making these, I'm merely passing on the info

Credits to Zeppelinrox for most of these tweaks, also credit to overmind for many of the build.prop tweaks

***BE SURE TO DO A BACKUP BEFORE THESE JUST IN CASE***

First is an 01sysctl mod just erase everything in the /etc/init.d/01sysctl file and copy/paste this in and make sure to return the permissions back- they should match all the other files permissions in there and a blank line at the end

Part 2 is the /system/build.prop same way as the sysctl tweaks just return the build.prop permissions to rw--r---r--- and be sure to leave a blank line at the end

And lastly add these lines to the beginning of /data/local.prop for an extra boost in 3g speeds and returning the permissions back again making sure to leave a blank line at the end

These may take a few reboots to take effect btw...and sorry if its a little messy, I posted from my phone

Isn't that what Chevy does for his rom? I feel like that's the point of a custom rom to begin with.

Yes and no, these type of modifications are quite as universally compatible like the build.prop ones in particular but they mostly work for everyone, the local.prop 3g tweaks he might not have even known about since they have to do more with the radio rather than the rom itself and the sysctl mods are from a lot of different sources and many have tested and tweaked them, so, for one he might not have had time to mess with them much anyway and secondly lots of Linux knowledgeable people have had plenty of time to tweak them

Personally the 3g tweaks are awesome...I went from 1.1Mbps-1.5Mbps download speeds up past 2Mbps and even some 2.6Mbps speeds (tested with speedtest.net app and website)

And I'm actually hoping Chevy himself could chime in and see what he thinks

How about a quick 'how-to' for us less knowledgeable folks?

[Jasko]

lol, I second this.

But thanks for all your help though, MS.

Ok ignore the second post then, that one has a few less stable edits...
For the first post make sure to have root explorer or similar root file manager. Copy the lines, then use your file manager to go to /system/etc/init.d and long press on the file 01sysctl and open it in the file editor and delete everything in it, then paste those lines in and saving it (make sure system is mounted rw first) then double check they stuck by viewing the file as text...if they did then reboot

Depending on your file manager you might have to change the files permissions to others rw and user rw before editing and then change them back after you've edited...should look like rwxr-x---
