Root SD partitioning

[Havoc40]

I typed in: a2sd reinstall and I think that worked. Flashing over top of Mik's was my problem. Now my issue is I can't open any of my apps! It force closes as soon as I click on anything. Hmmm?

It's probably a slightly older version of a2sd. Try a2sd reinstall instead. It will do the same thing.

Heh, I should have refreshed first. Ok, so everything force closes? First, try rebooting. If that doesn't help, run this:

su
a2sd fixapk

Let's see if that helps.

Thanks times a million. Has been a learning experience and thanks for walking me through it. Rebooting my phone worked and I'm all set. How can I tell exactly where my apps are on the card? I don't see any commands on his website for that.

All the commands are here. Here's how it works - Android will look in three places for apps:

/system/app
/data/app
/data/app-secure

/system/app is system apps that come with the phone or ROM. A2sd does absolutely nothing with these. These apps cannot be uninstalled (or pushed here) unless you have root. /data/app and /data/app-secure, however, is where the system will look for all your normal apps. As far as the system is concerned, all your apps are still there even after you have moved them with a2sd. A2sd does this by moving all your apps to the ext partition, which is mounted at /system/sd. When you go to the /system/sd directory, you're looking on the ext partition on your sdcard. If you go look now, you'll see app and app-secure directories. Inside those are your apps. The system knows they exist because a symlink (Linux terms for a shortcut) has been created that redirects from /data/app and /data/app-secure to /system/sd/app and /system/sd/app-secure. The same thing will happen if you move dalvik cache to the sdcard. The command is a2sd cachesd. That will move dalvik cache to the sdcard using the same method.

Now that we know that was the problem, you can probably get away with doing something like this if you want to keep your previous setup:

1) Wipe data/cache/dalvik/sd-ext
1) Restore previous nandroid backup
2) Wipe cache/davlik cache (don't wipe data)
3) Reflash ROM and whatever mods you want
4) Rerun a2sd commands to move apps to sdcard

I can't promise that will work, but it should be fine.

Thanks akazabam, hopefully this helps others in the future as well. There really isn't much on this process that I could find. I am moving dalvik cache to the card as we speak. I didn't have much for a "setup" considering I've had the phone for only 2 weeks, and have been doing nothing but flashing/wiping haha. I've got everything back pretty much the way I had it. Again, thanks for the help!

Excellent . I'll have to remember the solution to this one. Now I wonder why it didn't work when you flashed a2sd over it. In theory, it should have still worked. I'll look into it. I'm glad it's working now, though .
