Here ya go, my friend:
Free large file exchange service without size limits

@HeSaid: Thanks a bunch, made my day (and possibly ruined my evening, lol)

Open the zip file and take a look to the folder system\etc\init.d . You will see 5 files which tweaks ... something

These scripts are opened by calibration.sh which called by the updater-script.

I don't understand most of this code but I hope someone find this usefull.

Swap

Code:

#!/system/bin/sh

####################
SWAP=/data/swap
SIZE=128
####################

if [ -d /sys/block/mmcblk2/mmcblk2p2 ];
then
		/system/bin/busybox swapon /dev/block/mmcblk2p2
		/system/bin/busybox -w vm.swappiness=85
	if [ -f  $SWAP ];
	then
		/system/bin/busybox rm $SWAP
	fi
else
	if [ ! -f  $SWAP ];
	then
		/system/bin/busybox dd if=/dev/zero of=$SWAP bs=1M count=$SIZE
	fi
		/system/bin/busybox chmod 600 $SWAP
		/system/bin/busybox mkswap $SWAP
		/system/bin/busybox swapon $SWAP
		/system/bin/busybox -w vm.swappiness=85

@Hesaid, ty , started 3 hours ago , just woke up and checked it and still 3 hours to go, can turn this stupid computer off now ! lol

**closertozero** · 05-10-2012 12:08 AM

If it wasn't for the battery-indicator bug I would've kept this one. I found it to be noticably more responsive than earlier ones and less wifi-drops as well. I'm looking forward to the next rom from xxsl, if the battery-indicator works as supposed

**DrTricky** · 06-18-2012 07:10 PM

Hey does this have flash working 100% ? would be awesome to test this. (love testing new roms/tweaks :P makes me feel like a little kid with a new toy haha

) Hmmm the DalvikVM is a pretty scary thing to mess with, is the tweak working well? can anyone report any majour problems or crashes?

thanks

I don't know if it works under all circumstances, but for me, flash has worked everytime I've needed it.

Big problem is still the battery-indicator always at 100% (except when charging, then it sticks at 99%). But I hear not everyone gets that bug.

**galorin** · 06-20-2012 04:03 PM

I am one of the lucky ones, I am liking the mod so far, but I want to be able to dig in deeper, try to mellow out phantom touches, lock down wifi drivers, etc.

I wish I had source code, that would make it a lot easier.

It's not just that your battery stats need wiping or something is it?
