I was rooted and made the mistake of accepting the latest OTA update, which I assume was the new and devious 4.3. The update process seemed to work fine, but on reboot, phone is now freezing at the white Verizon logo screen.
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!
