Dood, I feel your pain, I just went through it. I lost my keys, I recovered them from hard drive surface, but I couln't do anything with the recovered wallet, why? well, I detected a bug in pywallet, it is not behaving well for litecoin.

Anyway, I managed after a lot of debugging to sort it out, and fixed it, partially.
Here is my repo on github https://github.com/magnux/pywallet, it is exactly the same as the original, except for the line 1231, where I changed "prefix = chr(128)" for "prefix = chr(176)". This small fix will let you dump your keys correctly.

You're not screwed, if you still have those recovered .dat of course.

So, the recipe:
1) Download MY pywallet https://github.com/magnux/pywallet.

2) Recover it:
If you have already recovered your wallet:, you can use your recovered .dat. It might issue a warning later, in the dumping phase, because of the chr mismatch, ignore it.
If you haven't:

Code:

python pywallet.py --otherversion 48 --recover --recov_size=<yoursize> --recov_outputdir=recovered/ --recov_device=<your device or file>

(I discovered that a .db file recovered by photorec works just as fine as recovering from the surface of the disk directly with pywallet)

3) Dump it(the info):

Code:

python pywallet.py --otherversion 48 --datadir=recovered/ --wallet=recovered_wallet_<yournumber>.dat --dumpwallet --passphrase=<yourpass> > litewallet.dump

4) Extract it:

Code:

cat litewallet.dump | grep "\"sec\":*" | sed 's/.*: \"//g' | sed 's/\",.*$//g' > liteprivatekeys.txt

This will extract all your keys in lines.

5) Import it:
Using litecoind, you can import it, this process is painstakingly slow, it has to rescan each time imports a key into the wallet.
Run the server and let it sync the block, after that you can use this line:

Code:

while read i; do echo "Importing Key: $i"; /<pathtolitecoind>/litecoind importprivkey $i; done < liteprivatekeys.txt

6) Enjoy:
This process will allow you recover your keys, guaranteed, I just done so with mine.
All your keys will be associated with the "" account, and you'll be able to get your coins out via litecoind sendtoaddress

I hope this helps the mankind.
