[MOD]Cache2SD

Hey developers!
We all know that our device has little memory. The Cache partition is only 64MB, of which only 20 are free!
Because of that, I'm going to show you how to use a folder on your SD card to download games and apps from the Android Market, instead of the default one(/cache/download)!
Requirements:
-Terminal Emulator (or ADB Shell)
-Root access
Tutorial:
1. Open Terminal Emulator
2. Type these commands in order:
Code:
su
mkdir /sdcard/cache-download
rm -rf /cache/download
ln -s /sdcard/cache-download /cache/download
3. Enjoy your Cache2SD!
This was tested and it works on SwiftDroid 2.0 RC1

Does this tweak speed up the phone in anyway?

No, but it allows you to download big games from the Market, like Pocket Legends, Drift Mania, etc.

Click to expand...
Click to collapse
terminal says: cp: can't preserve ownership of '/sdcard/cache-download/' : Operation not permited
Can you help me??

You don't have Root permission. Root your phone using SuperOneClick, for example.

I've found a fix: just don't run the line that causes problem and you should be good.

You have error because fat32 doesn't support extended attributes (file owner and group). Better solution is to create ext4/2/3 partition on sd card and set it mount point to cache or link it.

Thanks for your suggestion! I'll keep that in mind, but my method works good too.

If cache is just a partition we should be able to repartition internal memory and add 64mb to other one.

OKAY lets get started.
As u said that u have changed ur touchscreen so now i assume that u have a cypress one.
Now download the file attatched below , extract it and move it to
\system\lib\modules\"place the file here"
now open terminal emmulator
and type there
Code:
su
dmesg | grep ax8mt
now reboot ur phone.
LOL!!!

Ok, here's what you have to do.
1. Go into terminal emulator.
2. Type in:
Code:
su
dmesg | grep "cyttsp-i2c"
3. if you get something like this output:
Code:
<6>[ 4.185259] cyttsp_i2c_probe: Successful registration cyttsp-i2c
you have cypress and should use AX8MT.ko
If you did not have that output, you have synaptics and you should use X8gesture.ko.
4. Now that you know which digitizer you have, if you are not using a custom kernel or ROM with the modules auto-insmodded in, do this:
Add the correct module to /system/lib/modules
Enter in the following lines to terminal emulator:
Code:
su
chmod 644 /system/lib/modules/*module name*.ko
chown 0.0 /system/lib/modules/*module name*.ko
insmod /system/lib/modules/*module name*.ko
Then check in Multitouch visualiser if the module is loaded and working.
If working, add this line to /system/etc/hw_config.sh
Code:
# DT
insmod /system/lib/modules/*module name*.ko
Done! (hopefully)

ICS kernel sources available for download!!!

I compile the kernel source with "make star_p990_defconfig ARCH=arm", and you can download the binaries from :
http://pan.baidu.com/share/link?shareid=88597&uk=1293221681/
This should be the P990 kernel binaries , maybe someone can build a update.zip from it...
PS: I have no P990 , only has a SU660, so I can't test it...

here is update zip for kernel P990 compiled by marsgod. This may or may-not work.
This is untested, so take nandroid backup first. I will not be responsible for any data loss or phone brick.

V20C unsecure boot

Hi all,
I've been using official V20A with CWM installed and everything was great. But after updating to V20C I flashed unsecure boot to get CWM but I had a problem with WiFi not toggling. I remember that the unsecure boot of leaked V20A beta had the same issue with official V20A so gordon0001 created a new one.
Can anybody modify it or create a new one for V20C as well?

Can you upload the V20C kernel somewhere and then post a link here? To get it, issue these commands in terminal emulator:
su
cat /dev/block/mmcblk0p2 > /sdcard/v20cboot.img
You will find it in /sdcard with the name v20cboot.img
