SU Problem !!

[aus9]

hi

try at own risk but as you have posted in Mediatek forum root your phone with this
framaroot

2) go to playstore and get a su that might be different to yours

When you open it....hopefully it will give you an option to install using cwm
I suggest you do so......nope I think you need (4)

3) That stock recovery issue might indicate some kind of script or something else?
I think you will need to be rooted,
when you get a chance post any file names you see at the root of your device that are supect
/

EDIT
4) ensure you have mobileuncle installed
ensure you have your recovery image --the custom one.....named recovery-something.img on your SD card.
I call mine recovery.img but I have 2 I can choose from needrom.com

assuming you have already tested that mobileuncle can install a known recovery image onto your device
----try at own risk-----install the superuser via recovery mode----but your device needs to be rooted first AFAIK

this works on my phone but I have no confirmation it will work on yours


good luck
