My Gionee A1 plus started acting strange a month ago. It would often restart whenever I received any SMS notification and then boot up just fine. I tried using an earphone and keeping the phone in silent mode, as reducing the notification sound levels didn't help. This fixed the problem for a few weeks until 2 days ago while using my camera, it suddenly decided to restart but got stuck in a bootloop(the boot logo kept popping up and disappearing again and again). I managed to turn it off by plugging it to a charger where it went to charging mode.
After a bit of research, I entered the stock "Android recovery mode" and cleared the /cache partition but that did not fix the issue. I panicked as I did not have a twrp or any other recovery tool installed. I didn't even have USB debugging enabled. However, after a bit more strolling I found that fastboot could detect my device(after rebooting to bootloader) and then ran the command fastboot continue and my phone booted up alright. But now my phone can't use the "Ultrafast charge mode" which makes the charging process 5 times longer and the battery drains really quick. What's more the phone restarting by itself has become often(I can't even use my camera) and its always the bootloop. I have to use fastboot to boot in again.
I created a backup of my data and then did a factory reset on the device to no use.
Do I need to flash a stock ROM to my device or am I missing something? I am inexperienced in this domain so please guide me on how to fix this issue. I have attached snaps of my Recovery and Factory modes.
TLDR; phone ends up in bootloop after suddenly restarting while in use, battery drains faster, no ultrafast charging, clearing cache and factory reset doesn't help.
