This is kindof a long story, but here it goes.
When I got my phone, it came with the 9.20.1 update pre-installed. I downgraded it to 9.16.6 and rooted it from there. I attempted to unlock my bootloader, but I was having troubles with it so I just gave up. I began the update process to bring me back to 9.20.1 while keeping root, but I forgot to temp-unroot through Voodoo rootkeeper. When it boots into recovery to update, AP Fastboot pops up saying "Failed to lab check for recovery:0x56" and below it: "Fastboot Reason: Boot failure." This message pops up whenever I try to manually boot through recovery also. When I turn my phone on, it stays on for about a minute, then shuts off to attempt the update again, bringing me back to the Fastboot error screen. If anyone could help, that would be amazing. I don't care if I lose my data.
