well not sure why you would want to root a phone that has 0 support from developers. to me having a developer community supporting a phone is key. developers are the ones who find ways to root the phone. they make custom recoveries and custom roms....those are all what makes rooting a phone fun. no support means no fun.
having a custom recovery is the key. they are device specific and are essential to rooting phones. once a phone is rooted you can make nandroid backups with a custom recovery. nandroid backups are complete backups of your phone. they are kind of like a save point in a video game. if you mess up, you can always restore back to a previous point. this will be essential especially if the reason you want to root your phone is to delete bloatware or mess around with the os. if you do not know what you are doing, you can easily hard brick it. and without a custom recovery, there will be no way of restoring it.
always do you research first over at the xda website. especially if you know the next phone you get, you want to root it.
