[Help] LiquidNext + Swap, what to do?

[Guest Auxx]

Hi. Let me explain my problem.

I've decided to put lots of eye-candy into my old but still great Liquid. The only problem now is that I've run out of RAM. My ADW EX + live wallpaper take about 60 megs of RAM and I can't do anything :)

What I want to do:

1. Decrease size of /data by 40 megs and /system by 15 megs.
2. Add these 55 megs to /cache.
3. Put 100 mb swap on /cache.
4. Be happy!

My apps are on sd:ext, so I don't bother making /data smaller. Dalvik cache is also there. /system currently has 35 megs free, why to waste them? /cache is currently 78 megs, if I add 55, then I can safely donate 100 megs for swap, I think.

So here are the questions:

1. How to repartition internal memory?
2. How to put swap in /cache? I know this is possible.

I would be VERY thankful for help!

i had find some script to turn on swap on rom.and it also can mount when boot.i will release those script if some guys need it.

It's impossible to partition internal memory on liquid..

Hi,

I really like this questions :D

Change partitions is not impossible.. But hard and you can damage your device :) Some qualcomm tools can do that but i really ignore how to do that :)

anyway maybe i have some alternatives:

this is my partitions avaible space

As you can see my data partition is pretty empty. (i have dalvik,data and apps on ext2). So you could use a swap file in /data/ instead of create it on /cache/

SIZE=whatyouneed_MB*1024

dd if=/dev/zero of=/data/swapfile bs=1024 count=$SIZE

and than you can create swap fs

mkswap /data/swapfile

to mount it just

swapon /data/swapfile

i think it should work :P

wow the swap in /data ? hmmm a very interesting solution

[Guest Auxx]

Change partitions is not impossible.. But hard and you can damage your device :) Some qualcomm tools can do that but i really ignore how to do that :)

As far as I remember one of the Acer updates repartitioned ROM. I also found info that it can be done somehow, but did not have time investigate. I'll reflash everything now from scratch since I already ruined everything and will see how much space I will have. If you are right, then repartitioning won't be needed, that's great! Otherwise I will try the dangerous way, if anything goes wrong I'll just buy a new device :)

Thanks for your answer.

Last question - when I do swapon will it autosave and work after reboot?

[Guest Auxx]

Well, here's my report.

Yep, /data is HUGE! But I can't make swap work properly.

First of all you forgot to mention that swap file should be mounted to loopback:

# losetup /dev/block/loop0 /data/swapfile

# swapon /dev/block/loop0

Now the issues. loop0 is lost on reboot, this is sad and I'm too dumb to activate it. Second issue - now everything lags insanely (I'm using 1.7.1 with V6 tweaks from your wiki). Actually app launching lags. It took me about one minute to launch browser. After launch everything works like a breeze. Until you launch something else. Any suggestions on lags?

hey guys..it looks like only this thrd are alive now..haha

so im asking for help bout this...>>>

erasing 'system' - OKAY

suddenly it says "error: fastboot failed" then goes back to "process: fastboot" then "fastboot flash boot.img" and seems like loops back back to error fastboot failed.

you can put those script on init.d in order to mount when boot.i had confirm it 100% works.
