I don't know if it is because I rockboxed it, I used the reverse build, or if it is another problem, but my sansa e270 is screwed up. One of the CDs says it is 8 gigs in size and has system files inside that are each 4 gigs. I cant delete them, because it says it is read only. I tried un-checking read only, but it still will not let me delete them. Any suggestions? Should I format it, or will I lose the OS?
Update: What I have done so far is entrer recovery and I downloaded e200fw01.00.12.exe and tried to run it, it said it would format and asked if I was sure. I said yes and it said it couldn't it didn't have enough disk space. When I go to info on the sansa menu it says it has 5621 MB available, but when I open it through my PC and look at the Songs folder it says one of my CDs is 8 gigs in size and I can't delete it.
Update 2: I reset my settings and made sure USB was set to MTP which is the original one, I again entered recovery and finally was able to downgrade and format. It sucks I had to downgrade, but it looks like I got it fixed.
