This tutorial will share how to install cwm on your galaxy series, i have already done it by installing on my own device, samsung galaxy gio (GT-S5660), you can use cwm for :
1. full backup
2. full restore
3. flash your phone
4. etc

know bug :
E:can't mount /cache/recovery/command
E:can't mount /cache/recovery/log
E:can't mount /cache/recovery/last_log
E:can't mount /cache/recovery/last_log

this error is because recovery starting before block of devices were created. i still figure it how to fix it but until now i cannot find it.
for backup i am using Titanium Backup for now cause nandroid backup make my phone bootloop

but if you scare and wanna back to original, i only have for galaxy gio (sorry for ace and fit)
