My boot sequence looks like this: "SAMSUNG ([lock pic] Custom)" -> "SAMSUNG GALAXY S III" on black -> Swirly SAMSUNG logo on black -> Verizon animation on white -> HANG at indefinitely repeating few-frame loop animation of shining Verizon logo on white background.
I can get to Download mode - it looks like this:
PRODUCT NAME: SCH-I535
CUSTOM BINARY DOWNLOAD: Yes (2 counts)
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
QUALCOMM SECUREBOOT: ENABLE
*NO* mention of Warranty Bit.
Does this mean I am still on 4.1.2 and not dreaded 4.3 Knox? I don't want to screw up and accidentally brick this thing.
Unfortunately I have crappy notes from my original rooting, so I don't know if I had a simple root or custom ROM or custom bootloader or what. I know I have CF-Auto-Root-d2vzw-d2vzw-schi535.tar.md5, VRBMB1_Bootchain.tar.md5, and VRALEC.bootchain.tar.md5 in my work folder, and I was only rooting so I could use SGS3 Easy UMS so I likely did whatever method was needed for that.
How can I get back to functional? Stock or custom, I don't care, but with all the bricking dangers I'm reading about after this new OTA update I just want to proceed extra carefully. Also I'd really like to not have to wipe the phone with a factory reset or anything like that.
Thanks for your help!
