How to install Dark Tremor’s a2sd on Samsung Galaxy Ace (ext3/ext4)

This tutorial is for advanced users only. Read this tutorial before going ahead. This tutorial applies only to froyo/custom rom.

An easier way would be to install a custom rom.

Requirements:

• Your phone to be rooted
• Kerned modules for ext3/ext4 (In the zip file)
• a2sd modified.rar

Instructions:

1. Take a backup & then partition your sd card. Format the partition in fat32 & ext3/ext4.
2. Extract the contents of the “a2sd modified.rar” you downloaded above to the root of the sdcard.
3. Disconnect mass storage and login to ADB shell as root (alternatively you can use the terminal app on your phone):
   Code:
   adb shell
   su
4. Type in the following commands (try copy-paste each line then hit enter):
   Code:
   cp /sdcard/optimize/a2sd_enabler.sh /data/local/tmp/
   chmod 755 /data/local/tmp/a2sd_enabler.sh
   ./a2sd_enabler.sh
5. To double check everything, reboot your phone and login again as root through adb, then run the following command, and find a line similar to the highlighted line in the output below:
   su
   df
   Look for this line:
   /system/sd: 1032088K total, 38512K used, 993576K available (block size 4096)
6. If this line is present you can go ahead and do this:
   Reboot in recovery and apply “update.zip”

It also copies update.zip to the root of the sd so you can reboot and apply update.zip. This step enables a2sd.
