I have been searching for a while for any new tweaks to make our prevails even better (started thinking we had hit a ceiling, lol) then i found this

66Citbun

22 citbun is modified to work in conjunction with hroark's beta 5 ram script
22Citbun

these lines removed in 22Citbun
Code: 
#battery tweaks (vm) 
echo 0 > /proc/sys/vm/laptop_mode;
echo 500 > /proc/sys/vm/dirty_expire_centisecs;
echo 1000 > /proc/sys/vm/dirty_writeback_centisecs; 
echo 60 > /proc/sys/vm/dirty_ratio; 
echo 45 > /proc/sys/vm/dirty_background_ratio;
Its an all in one ram optimizer, 3g speed tweaker, battery saver, super-tweak.

i have tested this on a couple different prevails with no ill effects.
apps open faster, speedtest results increase, battery drain (when phone not in use) is noticeably affected

my brother plays the mmorpg 'tibia' and server connect time went from 2 min to around 30 sec and angry birds seems snappier to me too, just to name a few


NOTE THIS CONTAINS THE IPV4 SCRIPT TWEAKS INSIDE IT. I RECOMMEND REMOVING IT BEFORE INSTALLING THIS TWEAK
ALSO, YOU MUST BE ON A ROM THAT SUPPORTS INIT.D (ALL BUT STOCK SUPPORT THIS, I THINK)

installation is simple
1.MAKE A BACKUP in case you don't experience the same benefits.

2 a. dl 66Citbun from the link and extract the 'tweak' folder

2 b. OR 22Citbun and extract '22Citbun' file

3 a.inside is the 66Citbun tweak, copy '66citbun' to your sd card

3 b. OR copy 22citbun to sdcard

4.using a file explorer with SU (root explorer, es file explorer, astro, etc) copy/paste it from sd to /ect/init.d (it will be /ect/init.d/66Citbun)

5.reboot

please post your positive/negative results with this. and i did not create this, credit goes it Leonard Luangga. he made it, i just discovered the benefits from it on the prevail.

note to advanced users: there are some additional settings disabled in the script.:eek: as well as minor notes about them. i have not edited the script from its original state, if you choose to use the aditional settings, please post which changes offered more/less benifits:)

script contains

just installed this on my phone. running ctmod 2.4
all seems well for now. speedtests are running a little faster.
will report back later after using it for a while.
 
Got it going first test showed higher numbers will keep ya'll posted...oh yeah does this replace the tweaks by that rob guy you know the tutorial on switching your prl and other tweaks or do we still need to switch to a sprint prl....
 
Thanks man
Installed it and testing
Running ctmod right now
Speed test up a couple of points
Market seems to work little faster
apps opening about the same

Any one tested it on CM7?
And did anyone who tried the take out the ipv4 tweak?
Click to expand...

i am and have been running the script on cm7...it has quite a few tweeks in one little package..and has been working great since last friday..still experimenting with citbun and scripts like juwe11 ram optimization and v6.. ya kno...see how well it plays with others...also standby and idle decreased some sense running

this tweek wont effect your prl at all..but after you place it in init.d folder and reboot...you could check to see if your hidden menus settings are still the same...if your on stock or ctmod.. cm7 doesnt have hidden menu
 
I plan on trying this out. Lordvincent 90, you mentioned to remove the IPV4 Script, but where would I find it? I do have root explorer in case your wondering.

I think it is also in init.d, (could be wrong) i tried to redownload ipv4, to be sure, but it's been seized...

i factory reset/fresh installed before using this. maybe someone could check/confirm it's location for me :D

thanx for helping me (blindly) test this before i put it up here. You let me know it wasn't a placebo :)
 
Also trying it out on CM7... results are about the same as others... speedtest.net went up a little... still playing a bit more... gotta have some time to really tell... I'll let ya know how it goes... thanks...
 
Here is my speedtest results

what were they, at that time, in that location, before the tweak? You will not always get amazing speeds all day, every day, every place... There are many factors beyond what mods you use... mainly signal strength.

Trying it out now big Guy.
Do you extract the zip after placing it in said file? That way I can remove what you said to?
Click to expand...
i put 66citbun inside a folder named 'tweak' and zipped it. i tried just zipping the file but it wouldnt download on my phone for some reason. :rolleyes:
so extract zip (either with archidroid on phone, or whatever you use on pc) remove the 66citbun tweak from the folder, and place only 66citbun in init.d (/ect/init.d/66citbun)
 
Interesting... Since I installed CTMod 2.4 w/ DT a2sd, I've never been able to play Monopoly w/out long lag times and pauses. It was so bad the game was basically unplayable and I assumed it was because a2sd had it on the SD card. I removed the existing ram script, dropped this one in after removing the IP4 stuff, and it plays super smooth.
