I would read completely through the r3l3ased post to see if you might get an inkling about not working from 893. I think it will work, because remembering that one of the options is supposed to completely wipe your phone and put back to stock.
I was told that since we don't have an unlocked bootloader, that we cannot use Bionic Bootstrapper to go back n forth between ROMs, OTA loads, etc. Why is this? What does the Bootloader file (correct description?) have that prevents us from doing this? I was all happy going from 886 to 902 at first. Then I find out that we cannot restore to a different flash #; i.e. 902 back to 893 via saved Bootstrap BU.
See where I am going with this? I saved my bloated 886, 893 rooted, and 901 Bootstrap BU's. If I could restore back n forth between flashes,.... Would save a lot of heart ache worrying about bricking my phone.
Damn Moto and Verizon for making proprietary systems! I am used to being able to manipulate my PC how I want it. We should be able to do the same with our phones. I thought I had control issues!!
