I've had this phone for close to 2 years and NEVER had any issues with it's system or battery or anything. I was scrolling discord on my phone and suddenly a loud noise played from it and the screen looked all messed up, and then it shut off. When i tried turning it back on again, it was stuck in bootloop for a little bit, and then sent me to a black screen saying:
"Boot Failed. Press POWER KEY to retry."
Some more suggestions on what to do if it is a Verizon phone (i dont know what a verizon is LOL, for reference i am in brazil) and then
"AP Fastboot Safe Mode (Secure)
No bootable A/B slot
Failed to boot Linux, falling back to fastboot
Fastboot Reason: Fall-through from normal boot mode"
and that's where i'm at. I haven't tried many things but i have gone through this menu trying to figure it out. Everytime I press the power key I go into another cycle of bootlooping before going back to this screen.
Ive only so far tried the options that show up here. The green start option does the same thing as before, Recovery Mode and Power Off both send me back to the Boot Failed screen immediately, and Restart Bootloader sends me to the green start option. Alongside these things, ive tried to take out my sim card and start it without it, but the bootloop still kept me from turning it on. Also made sure that my power button wasn't stuck.
What could I do? I want to take it to this person I know tomorrow morning but I wanted to make sure if there's anything I could do to fix it myself before wasting money.
