Phone (Zenfone 6 ZS630KL) keeps booting into csc fastboot mode
Hello. Today, my wife's phone stopped responding to anything out of blue. I did a forced reboot (Vol down + power) and it rebooted and worked fine for a bit. Seeing as Android 10 was out, I dled fota file and flashed it via recovery from SD card, like I usually do. It flashed successfully and then rebooted. Once it booted, after a few seconds it hanged and became unresponsive again. Forced reboot once again, except this time it booted into a fastboot mode on its own and here lies there problem:
- going through an option to get into recovery mode doesn't help as it goes back into fastboot mode again
- rebooting through cmd doesn't help either
- pressing start just returns to fastboot mode - shutting it down through an option in fastboot and then turning it on still yields the same result.
Basically, whenever phone turns on, it goes into a fastboot mode whether you want it or not.
Seems like update failed to flash into slot B
(bootloader) has-slot:system:yes (bootloader) current-slot:a (bootloader) has-slot:boot:yes (bootloader) slot-retry-count:b:6 (bootloader) slot-unbootable:b:yes (bootloader) slot-successful:b:yes (bootloader) slot-retry-count:a:7 (bootloader) slot-unbootable:a:no (bootloader) slot-successful:a:yes (bootloader) slot-count:2
What can I do about this?
