ok but something is changed because the previous release 13.0.6 was via fastboot with the command windows_fastboot_update_rom.bat inside the file
now from 13.0.7 is via twrp. it's a little bit strange...or not?
in the new release for pocof3 13.0.7.0 after download and unpacked file with winrar don't see the windows_fastboot_update_rom.bat or update.bat
i've the stock bootloader. no twrp.
how can i update via fastboot without the file.bat?
