Thought I'd throw this up here. Seems much more readable on here than on the Ascend. If you don't know what this is, ignore it!

Instructions: Start Terminal Emulator, enter su, enter a2sd <command>

I cant get my Delvik to move to my SD. I opened TU and typed in "su" and the "a2sd check" and it says something like "Set up issue Run a2sd repair to fix" and when I run "a2sd repair" it runs and then my phone but then when I run a2sd check again it tells me "Set up issue Run a2sd repair to fix"" again. So should I run "cachesd" to try and move it?

Also next to swap it says "Partition not present or no swap support" then under that it says "Swap does not start" I made a swap partition at 32mb. Do I need to run one of the swap commands to make it work?

Okay I downloaded that and as soon as it goes to install I get a FC that says The application Package Access Helper (process com.android.defcontainer) has stopped unexpectedly" and its now just stuck on "installing" I noticed under requirements it says "2.2 - 2.3.3" I have 2.3.5 maybe thats why?



Now Im getting force closes for literally everything. F@%*^#&^$&$&! Ahaha Reflash here we come!

A2SDGUI works on CM7 07282011 (GINGERBREAD 2.3.5)

Try using the 'fix permissions' function in ROM MANAGER before resorting to a re-flash of your ROM.
It takes a couple of re-boots for everything to settle in after moving the DALVIK CACHE to SD.
Also, as stated in the ULTIMATE ASCEND CUSTOMIZATION GUIDE, you are recommended to have a CLASS 4 or better SDcard before using DT'S A2SD or you will more than likely experience problems.

I ran fix permissions twice in RM and twice in CWR. None of that happen till I tried to download a2sdgui. Every app I tried to open would FC and a crap load of .process' were FC and then after doing fix permissions I RM started force closing on me. I already wiped it all and reflashed tho. Yeah I have a class 4.

Can't explain why you're having problems w/A2SDGUI, I was running it, along w/CM7 07282011 w/a CLASS 2 card before recently switching to a CLASS 10 Card.
A re-flash of your ROM may be in order.

I'm having the same problem. With a class 10 card. But since I'm on vacation, I think I'll wait to try anything.

From what Ive read EXT 2 or 3 is recommended over 4 for Android. If that is in fact true I dont know. I partitioned mine as a EXT3


ext2, ext3 and ext4 are all filesystems created for Linux. This article explains the following:
