Looks like it'll do all the same things. Obviously I can't vouch for it as I could the method I posted, but people seem to say it works... I assume that you'll have the same thing with unlocking the bootloader completely wiping the entire device back to stock, so back stuff up!
Still haven't unlocked the bootloader etc due to not having a PC... Is this the same thing?
