@oddtail @aoanla so in the case of a software issue bricking the phone, that's often because of the phone only having eMMC or UFS storage, and not a separate chip for the firmware but you can do the same thing to a desktop or laptop with a bad BIOS update, it's just on a phone, the bootloader (the equivalent of the BIOS) is stored on the same flash chip as everything else. (also some low-end laptops nowadays do the same thing!) however, they have to get the bootloader on there for the first time at the factory, and there's usually a first-stage bootloader in non-writable ROM on the CPU that's used for that. the old-school way of unbricking when the bootloader was corrupt was to use a JTAG debug interface to directly access the hardware to flash a good bootloader. the new-school way is to use USB Device Firmware Update - the first stage bootloader will let the thing show up over USB and accept a good firmware image.
