I was following the installation guide and things were going smoothly until I started flashing the recovery.img
For some reason the phone started power cycling, which interrupted the flash. Unplugging and re-plugging it in seemed to resolve it, and it got back to bootloader mode. I flashed the recovery image onto it and tried entering recovery mode, but now it only goes to the bootloader, irrespective of the option I choose.
Is the phone screwed, or can I salvage this?
ED. Fastboot detects the phone when it’s plugged in but adb does not
Okay, problem resolved.
It seems the vendor ID and Product ID in the udev rules changed, so I had to update them to connect to adb.
I also re-uploaded the boot, dtbo, recovery, etc IMG files. Then I was able to load into LineageOS recovery mode
