I've rooted my other android phone from KINGROOT.net . But the site doesn't let me anymore.
Is there any other sites to root your android from your phone? (No usb)
Not using USB severely limits your potential rooting methods. Obviously the best way to find methods is Googling your phone model and "root." Why didn't you specify your phone anyway?
Find a computer, if you REALLY want to, you will be able to.
