EDIT 3 : Got adb access !!! . Now if someone could assist in the reversal commands. Theres a point or two I don't get. Thanks.

To undo I believe these are the steps (Based on my linux knowledge), if you followed the initial steps 100% correctly/completely:

su
rm /data/data (This will delete your symlink)
mv /data/data.bak /data/data (Restore your backup)
reboot

I tried before i posted, but the list came out really long, but i did not see anything that says data/data or dbdata

edit : or maybe i cant see it because it's on top of the list and i do not know how to scroll it back up.

edit 2 : ok got it, he did not mention du -h data/data. doh

I re-flashed the phone and re-did the steps and it works fine. Everything seems to be zipping along, but some testing is needed yet. Thanks @megakid for your assistance, but the phone lost adb access and I was ... well screwed by then !!!

[flash_235]

This is great.  The phone is superfast now.  I have over 20 apps install and only 20.53MB used.

[Toreak]

I uninstalled Google earth just to get /data/data down to 80Mb. After following the steps, the phone is blazing fast now. Thanks Paul.

[nikker]

The data foder in my phone is too large, more than 300MB. I didn't install google earth, just some gameloft games.

I wonder whether there is any other ways to mv and ln some parts in the data folder, not all things in data folder.

Thanks.

THANKS TO PAUL!

This is my first smartphone and I managed to follow the instructions and it worked I think, I am not sure how to see if it did, but the adb commands went off without a hitch and then rebooted fine. Phone is running well (not sure if same or better though)

They've kinda done that already, if you have a look around dbdata. There's other partitions that seem to be unmounted, gonna look into what they are for...

P

ok I saw that. but it's for db. maybe we can try with those core apps with huge cache/file in /data/data first, and i noticed its namely the com.android.providers/emails, imes and maybe the launcher.

now I am wondering, Galaxy S has 512MB RAM, 2G ROM and 16G internal storage.

I see that the 16G internal storage is mounted on /sdcard

and 2G ROM apparently has been partitition into multiple blocks and mounted as folders such as /system and /data ?

If so, what's rootfs (and the fs that mounts dbdata?)  part of the 512MB RAM?

Check your /data/data first to see which apps are storing lots of data in the megabyte range. Here's how:
adb shell
su
cd /data/data
busybox du -h|busybox grep M

games like gameloft games do take a few Mbs and google earth took about 20Mb. Unless there are new workarounds, the easiest way right now is to uninstall those apps that u can do without that takes up megs of space in /data/data. Alternative is try to identify apps that cause the stall and create symbolic links for those apps' data to /dbdata

THANKS TO PAUL!

I've already done it, the phone is super fast now. But i also want to know, can the new apps install to /data/data again? instead of /dbdata/data

like to fuction App2SD

Actually there is workaround - I just did it

I just linked everything except biggest folders in /data/data to /dbdata/data, and biggest folders linked separately each one so they would be in /data/data.bak/.

full script is here:

su
cp -rp /data/data /data/data_to_copy/
cd /data/data_to_copy
rm -r com.navngo.igo.javaclient
rm -r com.google.earth
rm -r com.navigon.navigator

rm -r com.polarbit.rthunder2
cp -rp /data/data_to_copy /dbdata/data/

mv /data/data /data/data.bak

Weird goings on ..... being lightly using the phone for 1 hour and 50% battery gone ... something aint right. Not sure if any wiping was needed before reflashing, but Ive just flashed again !

I suppose you are replying in the wrong topic.

This's GREAT!
