This mod is based on the I570EXXJE4 firmware with LK2.06.beta4

I made this for my own phone to make it easier when installing a clean firmware.

All you need to do is:
1. Flash new firmware (eg: I570EXXJE4) using ODIN
2. Flash LK2.06.beta4 using ODIN
3. Boot into recovery & apply this MOD

Optional:
Clear Data/Cache

I have based it on the latest firmware at the moment (I570EXXJE4)
Basics of installing the mod – install I570EXXJE4 – install LK2.06beta4 – install equkmod

What the mod does at the moment:

Removes unwanted system apps

Installs

su 2.1, from xda-forums to fix su
ARM11 dalvik-vm, from sdx-developers (have left out JIT due to stability)
ARM11 calculator fix, from sdx-developers

todo:

install custom hosts file for adblocking

On looking into the problem with memory usage on the samsung i5700 it seems the system is creating memory dumps from the debugger process.
These seem to mount up and use huge amounts of memory cuasing the /data partition to fill up quickly.

This may be cuased by installing JIT (unconfirmed atm)

These files were taking up 65mb of storage on my phone (on a 150mb partition).

65.7M   /data/tombstones

I have now added to the script which relocates dalvik-cache to the /cache partition so on every reboot these files are removed.

After applying this new mod I have nearly 100mb of free space on /data.

Filesystem                Size      Used Available Use% Mounted on
tmpfs                    80.7M     12.0K     80.7M   0% /dev
tmpfs                     4.0M         0      4.0M   0% /sqlite_stmt_journals

/dev/stl5               147.1M     52.8M     94.3M  36% /data
/dev/stl7                78.7M     41.9M     36.8M  53% /cache

/dev/stl7                78.7M     41.9M     36.8M  53% /data/dalvik-cache

I just had a problem with my i5700 where the phone storage filled up.

After looking into the problem it seemed the main cause was the dalvik cache using up 45mb of the /data partition of the phone.

df
Filesystem           1K-blocks      Used Available Use% Mounted on
tmpfs                    82624        12     82612   0% /dev
tmpfs                     4096         0      4096   0% /sqlite_stmt_journals
/dev/stl6               200996    133660     67336  66% /system
/dev/stl5               150644    150184       460 100% /data
/dev/stl7                80576      4180     76396   5% /cache
/dev/stl10                7729       776      6953  10% /efs
/dev/bml8                 4096      4096         0 100% /xbin

Basics on the filesystem layout:
(512mb is divided into partitions)
/dev 82mb
/system 200mb
/data 150mb
/cache 80mb

I thought why can’t we move/repoint dalvik-cache to this nearly empty partition?
I had already heard that people had used SDCards for this but I think that is pretty pointless as SDCards are slow and should be classed as removable storage (ie – you should be able to boot without them)
On searching around I found someone had actually done this before without any problems.

The script makes the system put dalvik cache into the /cache partition which is 80mb and gets used by various processes for caching & OTA updates (prob don’t have those anymore anyway)

Result:

df
Filesystem 1K-blocks Used Available Use% Mounted on
tmpfs 82624 12 82612 0% /dev
tmpfs 4096 0 4096 0% /sqlite_stmt_journals
/dev/stl6 200996 133668 67328 67% /system
/dev/stl5 150644 105580 45064 70% /data
/dev/stl7 80576 41962 38614 52% /cache
/dev/stl10 7729 776 6953 10% /efs
/dev/bml8 4096 4096 0 100% /xbin
/dev/stl7 80576 41962 38614 52% /data/dalvik-cache

Now another 45mb of storage for more apps and dalvik is still writing to the internal storage
note: in comparison the htc desire only has a 40mb /cache partition

WARNING: THIS METHOD CAN BE DANGEROUS. DO NOT TRY IF YOU DO NOT KNOW WHAT YOU ARE DOING.
I CAN’T BE RESPONSIBLE IF YOU BRICK YOUR PHONE.

Update: I have now made a mod zip which can be applied using recovery – Link
