Just now flashed my 52246s to newest firmware 6s07.
Now I know why everyone bashes the Windows flasher, in the past it has served me well, but today it failed me:( .
I rebooted and had been in the middle of some ATIP checks. I went to read some more and…nothing? Tried 3 ATIP readers and it was acting like a CD drive. I went back to 6s02 (mtkflash) and it worked fine. I was about to post here demanding why rdgrimes of the cd media forum hadn’t said anything yet, but decided to mtkflash 6s07. Now it’s working. I guess I’ll be using mtkflash for firmware updates from now on.
