Thanks for this helpful post. Unfortunately I'm getting stuck in step 1. :-( I start up Odin, load the PIT and PDA files, check re-partition and click Start. It sits on modem.bin for a minute, then my phone turns off - messing up the whole process.
I installed HashCheck to check CI500_VZW_EB01_FROYO_REL.tar.md5 - but HashCheck wont run it. It says "Cannot load..". I thought maybe the md5 was corrupt so I tried downloading it again. Unfortunately I get the same result.
Is there something else I can try?
