It's fixable. How's your ADB/command prompt knowledge?

SOLVED: messed up partitions on internal storage - CyanogenMod Forum

 

Don't think so. I worked with a guy on this a month or so ago and I found some cliff notes from an email which I'll post. First you need to download Parted from the Cyanogenforums link. Then extract the 6 files to the sdk tools folder. My commands also assume you placed sdk on the root of your C drive. Once you have the files in the tools folder:

cd\sdk\tools
You should then see this:
C:\sdk\tools> (blinking cursor here)

adb push {insert filename 1-6 here} /sbin/
(Note the addition of spaces MUST be correct on all commands from here on out. There's one after the word "push" and one after the filename you're going to enter. I'm only adding the { } brackets for emphasis. They're not used in any true push command.

Once you get all those 6 files pushed to /sbin/ the next thing you do is:

adb shell
Should now see a # come up. (this verifies root access) After the # at the blinking cursor, you do this:

cd /sbin/
chmod 0755 {file 1-6 here}

After those 6 entries and while still at /sbin, do this:

parted dev/block/mmcblk0 mkfs ext2

Then enter "1", then "ext2", then move on to partition 2 and do the same

 

No prob. Good to hear you're back in the game.
