[SCRIPTS] & [TWEAKS] - Updated 2.22.13

dSlice · Nov 9, 2012

*****************************************************************************************************************
OK! Listen up! A little disclaimer before we begin...

XDA, Dwitherell and I are not responsible for you borking your phone while using these scripts!

*****************************************************************************************************************

Now that, that is done and over with let's begin, shall we?

I have scoured the vast online community, that is the great XDA and have researched and tested various scripts(init.d) and tweaks(build.prop and gps.conf) to help our greatly handicapped Droid Charge somewhat "compete" with the big boys.

Dwitherell has kindly uploaded them to Tweaktools.

You may ask init.d? But we have a stock kernel that doesn't support init.d... Thanks to this post and Dwitherell's genius we have working init.d baked right into our ROM, yes that's right baked in!

P.S. - We now have a custom kernel that is able to use init.d tweaks without any hacks... Lazarus Recharged Kernel

RENICE Tutorial

Renice operates on the principal that the lower the value of the process (the scale is from -20 to +19), the higher the priority the process has on CPU time. In other words, a process that is nice to others, is +19. One that isn’t so nice is at -20. In function then, a process that requires lots of immediate CPU time such as a launcher, benefits from running at a higher priority (thus as a negative on the niceness scale) than, say, Google Maps.

***MAKE SURE TO CHANGE THE FIRST TWO ENTRYS TO YOUR CORRESPONDING PROGRAMS!***

***To add/remove other program names, change the PNAME value.***

Simply open your favorite file explorer(I recomend Script Manager, it is an all around good program), navigate to /data/data and in there are your programs. What I do is long press(in Script Manager) on the program select rename and copy the name, then paste it into the renice script. Simple as that.

Another way is to go to the Play Store find the app that you're trying to re-nice and click the share icon select Gmail or Messaging and you'll get a link. At the end of the link you'll see id=xxx.xxxxxxx.xxxxxxx copy what's after the equals sign and simply paste that into the script.

Feel free to add/delete programs from the list to suit your needs, as well as change the priority values.

Anywho, here is a run down of each of the modifications...

Script Manager Scripts

These are from V6 SuperCharger that Zeppelinrox made

Fast Engine Flush (Clears Cache and Frees RAM)
Detailing (Defrags the system)
Super Clean (Wipes Dalvik Cache)

These work great as a Script Manager Widget. All you have to do is click it and you are good.

Install Instructions:
1. Download from the links below
2. Place on root of SD Card or create a folder called Scripts on SD Card
3. Open Script Mananger
4. Locate scripts
5. Click on script
6. Click Fav (Star) and Su (Skull and Cross bones)
7. Click Save
8. Repeat 4 - 7 for additional scripts.
9. Go Home
10. Add a new widget to your desired home screen.
11. Select SMWidgets
12. Select script
13. Repeat 9 - 12 for additional scripts.
14. Enjoy!

If you come across any others left me know and I'll add it in(with credit of course). That is all. Have fun! :good:

Have you seen the AGPS patch here? http://xdaforums.com/showthread.php?t=1250226

Grab the Google specific No-SSL version. It's the one I bundle with my Rezound rom, and it's fantastic. He runs his own XTRA servers, updated with fresh data every 30 minutes, and runs his own stratum 2 NTP server just for AGPS. The patch also contains a lot more config tweaks related to AGPS timouts and accuracy requirements. The Rezound GPS isn't bad on it's own, but that gives it into the best GPS performance I've ever seen, including my $350 handheld. It locks in 2 seconds, locks to multiple satellites indoors, gives sub-10ft accuracy, etc. I don't know how well it will do on the Charge, but seeing as how both phones use Qualcomm chipsets, I can't imagine that it wouldn't work for the Charge.

No but I have now and will research that. Thanks Shrike!

After enabling init.d... if I want all the 77tweaks...all I need to do is follow the placement stated to install it (/system/etc/init.d) ?

That is correct.

Also after putting in the new renice scripts...They will be accessible via tweaktools? Just needing clarification

Awesome work!

Or a step by step would be greatly helpful please

"Change based on your needs" what do I do?

They will be in Tweaktools when 3.1 is released.

I updated the OP with renice instructions.

First lock took about 10 seconds, second lock was instant. Thanks again shrike!

Just installed with no issues and performed the required 2 reboots. The second reboot was three times faster than any other time I've rebooted. Is this a benefit of the tweaks?

Thanks for contributing to the community! I love that we still have active devs

Glad to hear it works well here. I remember GPS being awful and inconsistent on this phone.

JihadSquad · Nov 9, 2012

Holy crap shrike. On my first go it locked onto 12 sats in 15 seconds on a cloudy day. The thread says the first time takes usually 20 seconds so I'm looking forward to using this over time.

I did something wrong. I installed init.d then copied 77tweaks and renice into the init.d file. I rebooted it once and it went fine. Then after i replaced the build.prop file with the down loaded one I restarted it and it went into boot loop. At least I guess that's what it is when it turns the Samsung screen off and on and won't go past it. I re-odin'd Tweaked plus cwm and fixed it.

Question for ya, what program are you using to replace the build.prop with?

Hum. Did you mount the system as R/W? Also maybe try using Script Manager and see if that does anything.

[SCRIPTS] & [TWEAKS] - Updated 2.22.13

Did these help modifications help at all?

YES!!! :D

NO!!!! >:[

Maybe?

Haven't tried it yet. :/
