The steps I preform are:
(1. Turn the device off
(2. Boot into AP fastboot by holding down the volume + and - buttons, turning on the device, and selecting AP Fastboot as prompted
(3. Run the command "fastboot flash recovery <filename>.img"
(4. Have the following returned:
> sending 'recovery' (8228 KB)...
> OKAY [ 0.640s]
> writing 'recovery'...
> OKAY [ 2.180s]
> finished. total time: 2.820s
(5. Run the command "fastboot boot <filename.img>"
(6. Have the following returned:
> downloading 'boot.img'...
> OKAY [ 0.640s]
> Command restricted
> FAILED (remote failure)
> finished. total time: 0.730s
(7. Run the command: "fastboot continue" to regain access to my phone
Also, when I boot into the boot selector and select the recovery option, it will show the "Warning, your warranty is void" prompt, flicker, then show the prompt again, which I presumed to be the phone flashing back the stock recovery, which I hadn't had previous success accessing fully either, and then continue to boot normally. Because of that, I used RootBrowser on my device and proceeded to move the "recovery-from-boot.p" file from it's /system home to /storage/emulated/0/Download in the case that I needed it again in the future.
Moving said ".p" file yielded no different result in the aforementioned fastboot commands. However, when I boot into recovery on the device itself via the boot selector, it will hang (let it run for five minutes at one point) at the "Warranty Void" screen, then restart into AP Fastboot after holding the power button, at which point I am unable to turn on the device and need to run the "fastboot continue" command to be able to access my device again. I will also need to run said command every time I want to restart my phone.
Copying said ".p" file back caused the device to again hang at the "Warning: Bootloader Unlocked" screen before I held down the power button which cause it to run AP Fastboot, at which point I could run the "fastboot continue" command and access my phone again.
Suffice to say I'm in a bit of a pickle and am a little lost as to how to get myself out of it. Any help would be greatly appreciated!
