How To Unlock MM Bootloader And Obtain Root For Dev Bootloaders Only​

This should work for you people having trouble reading SDCard. This bypasses the SD card altogether, so there shouldn't be any more issues. If you have never unlocked your bootloader yet DO NOT USE THIS METHOD. Your CID needs to already have been changed to use this method. Thanks to [MENTION=1949695]jrkruse[/MENTION] for letting me use and update these instructions, any other references to "me" or "my" are [MENTION=1949695]jrkruse[/MENTION]. [MENTION=1949695]jrkruse[/MENTION] created the MMBootloader_Unlocker_NoSD.apk, I modified the unlocker script to bypass SD cards.
