the auto installer for pc is simple, all i did was take the commands you would normally use and put them in a .bat file for a windows pc
adb reboot bootloader
fastboot flash recovery recovery.img
and have the thing you wanna flash named recovery.img, as well as the fastboot and adb programs in the same folder as the .bat you made. done and done. and if you want to make it fancy
adb reboot bootloader
fastboot flash recovery %1
that will make it drag and drop capable, meaning if you drag any image from anywhere no matter what its called itll install it for you. just gotta still have it and both the fastboot and adb programs in the same directory as your batch file
this can even be done with the dd/adb method
adb push %1 /cache/recovery.img
adb shell "su -c 'dd if=/cache/recovery.img of=/dev/block/mmcblk0p13; rm /cache/recovery.img'
i might come out with an updated installer, but i make no promises, and whatever you do dont drag and drop the wrong files onto those lol you wont like what you get
