so....using this app, i have selected the bootloader i want to change to, and it says it is downloading, but when i reboot, it doesnt change the bootloader. i go into astro file manager and i can find the boot animation on the sd card as a zip file. i go into droid2 bootstrapper and boot into clockwork and try to install the zip file, and it aborts the download. tried it on 2 different bootloaders. any clue?
