No, it is not possible. AFAIKI am not talking about flashing zip files from my phone. I was talking about using the fastboot binary that I have downloaded in "~/android-sdk-linux/platform-tools/" folder on my laptop to flash the files to my phone which is connected to the laptop through usb and is in fastboot mode. I am not modifying zip files to flash them from the phone.
I was just wondering:
A.) Is it possible to do using the "fastboot flash <partition> [ <filename> ]" command from the terminal on my computer? I have flashed radios using this command in the past and that is why I thought that it might work.
B.) Will doing so bypass the software compatibility check that the PG06IMG.zip method uses?
The reason I am wondering is because I am interested in how fastboot interacts with the bootloader. Sorry for any confusion.
