Did you perform a back up before doing the battery mod?  If so, just restore it...

If not, try booting into recovery, and wiping cache and dalvik.  May work, but I'm guessing not...  Make a new backup while you're there (might be able to pull your data from it later, if you have to do a fresh install of CM)

Would really help if you knew what mod you installed.  Do you still have the zip on your SD?

U need to do some more research it seems. The answers are in forums, I didn't know anything about this stuff a couple months ago and now I'm good enough, and its from Googling and reading. I'm sorry, but you run the risk of data loss when ur flashing roms. The process to prevent this isn't terribly hard.

1) backup in Titanium
2) put ur desired Rom on SD card if it isn't yet
3) perform nandroid backup
4) reboot to recovery
5) wipe caches
6) flash desired rom
7) restore apps and system data from Titanium

If I have problems with boot loops or don't like the rom or whatever, reboot to recovery, wipe caches, restore nandroid. Simple.

Google even backs up some app data on the market.

If u have to start over since u don't have  a CM rom on nandroid backup, so be it.

Ah. Man that is gonna be hard to do, I think I would just opt for a clean install, even it means losing a little data. :-)

The location of the backup depends on how you made it...  I believe Clockwork uses the Clockword folder ROM the SD card.

If you extract the backup, you can pull individual items.  Make sure you are on the same version of the same ROM that crashed.  You can probably replace your apps quite easily.  You can also try replacing data, but go slowly, a file at a time, and make sure each file works (probably have to reboot after each file).  Make a backup before each change, so that you can rollback if something goes wrong...

Gonna be long and slow.
I would start with what you think are the most important files first...
If there's something you can't live without, try and restore, else, just live with it...

What are you most concerned about restoring?

Good luck!
