[SCRIPTS] [HOWTO´S] (untested) app2sd, sd card speed fix script | how to guides |
hi all! im new TF user but i tough i could post here some fixes and scripts that i use on my Samsung galaxy 3 but beaware that i have not tested these but they should work on every device
im not responsible for any damage that may occur when you apply these scripts!!
1st there are 3 app2sd scripts
What is App2sd?
App2sd is a utility which automatically moves some/all your data partition to your ext sd partition. So, your internal space is partially/not used :P
Which app2sd version should i choose?
As you can see, there are 3 versions: App2sd-v1, App2sd-v2 & App2sd-v3.
Differences in versions App2sd-v1: It is the normal app2sd script. This script moves your /data/app/ & /data/log/ to your sdcard's ext partition. It is very fast but your real internal space will be full if you install many apps. This version is not recommended. :P App2sd-v2: It is an enchanced version of app2sd, which moves /data/app/, /data/log/ & /data/dalvik-cache/ to your sdcard's ext partition. It is fast and you can install many apps until your internal memory reaches 0mb.. Is is recommended for sdcards class2 - class4. App2sd-v3: It is an ultra enchanced version of app2sd, which is like data2sd, but you won't have so many lag like data2sd. App2sd-v3 moves /data/app/, /data/log/, /data/dalvik-cache/ & /data/data/ to your sdcard's ext partition. Your internal memory won't be used unless you do install so many apps and your sdcard's partition get full! SDcard class6+ is highly recommended! Conlusion: If you have class2 or class4 sdcard use App2sd-v2. If you have class6 sdcard use App2sd-v3.
You must have a kernel which supports init.d & ext4. And you must have an ext partition in your sdcard. Ext4 is recommended. And last thing... You need android 2.2.
How do i check my sdcard's class?
Remove your sdcard from your phone and check if you see a circle with a number. :P If your dont see anything, you may have a class2 sdcard.
How to partition my sdcard?
Download MiniTool Partition Wizard Home Edition 6.0. But make a backup before :P
How to install the script?
Take a nandroid backup. Download it from links below and decompress it to your sd. You can either adb push this script in /system/etc/init.d/ or copy it with root eplorer to /system/etc/init.d/. Type the commands: adb shell (adb only) su mount -o rw,remount /dev/block/stl6 /system chmod 777 /system/etc/init.d/* chown 0.0 /system/etc/init.d/* Then reboot in recovery and do a wipe data/factory reset. All your data will be wiped. From now on some/all of your data (depends on the script version) will be moved to your sd automatically. Before you restore your apps with titanium, go in titanium preferences and select to force restore apps to internal memory. Don't move apps to external!!
Why i see only 200mb as internal? App2sd is invisible :P You can check your sdcard's ext partition in Titanium Backup.
=> app2sd script v.1
=>app2sd script v.2
=> app2sd script v.3

who introduced these on SG3!
then there is sd card reading speed fix
How to make it work!
At first it needs root & busybox...
Download the script
, choose the cache size you want between 1024, 2048, 3072, 4096 kb! (Recommended size: 2048kb)
Extract the .zip file you downloaded and put the 77sdcardspeedfix in your sdcard.
Run root explorer and move the file in /system/etc/init.d/ (If there is no init.d folder, create one!).
You can also adb push 77sdcardspeedfix /system/etc/init.d/
Run a Terminal Emulator/Adb and type the commands:
adb shell (if you are using Terminal Emulator, skip this command)
chmod 777 /system/etc/init.d/77sdcardspeedfix
chown 0.0 /system/etc/init.d/77sdcardspeedfix
After that the phone will reboot. You will see that your sdcard reading speed has increased!
