Had the problem. Reflashed to stock PR 1.3 kernel. No problems now. Just d/ling my apps again now after I restored the backup.

As for flashing on Win 7 64, I just did it and it worked fine.

I tried to do it on Ubuntu in Virtualbox but it was giving me trouble with installing the flasher so I said "f*** it" and used Win7 64 after all. No problems (just be sure to download the correct .bin .)
