After installing FR12 custom ROM Vanilla Edition on my phone, I wanted to get back to stock so I installed - back to ext3 zip. Then when I tried to restore the stoc ROM, I got the error MD5 mismatch!
I want to specify that I tried a custom ROM before but with ext3, and I had no problem to return to the stock ROM.
