Question [Q][HELP]Bootloop on Froyo

Hi

I just made an Error when recovering a softbricked i9003

Got the phone from eBay, ROM-Version was unknown. Made a flash to DDLF2, could boot, but had no Network. It was very instable and ended up in a Bootloop.

Then this happened:

- Flash to Froyo XXKB3 -> worked flawlessly, including calls.
- Flash to DDLF2, Phone doesn't boot (Screen fades to Black)

Then I tried going back to XXKB3 but now I got bootloop and in Recovery it says, that the internal SD can't be mounted and this:

Quote:
movinand read fail
lfs pass open fail
So I paniced

- Then flashed KPE -> Screen fades to Black again -> more panic

Now I'm stuck with KB3: With additional PIT I get it at least to bootlooping..
All other threads that I found concerning Bootloop are focused on GB installs, but I'm still with Froyo. Do I need a Froyo bootlader? Where would I get it? Is there any solution?
