YavychAs a layman with very minimal experience flashing Android phones, I would recommend contacting your regional ASUS Support for a repair.
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
What can I do about this?
Phone (Zenfone 6 ZS630KL) keeps booting into csc fastboot mode
YavychThat's why I'm thinking Support is your only option here. If you can't do anything on the software side because the device is locked in a loop, Support might need to arrange a swap for you.
Hello, contacting local asus support is not an option.
Removing SD card doesn't anyhow help either.
I'd honestly try to just flash fw through fastboot into slot B, alas, that's not possible because device is locked.
