SuperSU zip
TWRP ported by me

MTK 6577 scatter file
Place the scatter file and TWRP recovery in the SAME FOLDER. Rename TWRP-OmegaHD.img to recovery.img.
1. While the phone is still on, enable USB debugging (Settings > Developer options) then plug into PC. Mount your phone as USB Storage. Go to the root of your sdcard and copy pcdrivers.zip to PC. Extract and allow drivers to install. Install the MTK drivers as well (download from my Mediafire).
2. Mount phone as USB storage. Copy SuperSU zip to internal or external SD card. Unmount USB storage, then unplug phone from PC.
2. Turn off phone. Remove the battery.
3. Start SP Flash Tool. Under "Scatter-loading," choose the MT6577_Android_scatter_emmc.txt. You will see that RECOVERY has a check beside it. Click on "Download." A warning will appear, proceed anyway.
4. With your phone still off and the battery out, plug it in to the PC. Flashing should start. It will only take a few seconds. You'll see a green circle when it's done.
5. Unplug USB cable and put the battery back.
6. Enter recovery mode by Power and Volume + button. Release both buttons when you see the boot menu. Use Volume + to highlight "recovery." Then use Volume - to confirm.
7. Click "Install." Choose the appropriate tab (internal or external SD card).
8. Select UPDATE-SuperSU-1.25 zip. Swipe to confirm the update. It will flash. Go back to main menu of TWRP.
9. Click "Reboot system." Wait until you are fully booted into your homesceen.
10. Once booted, you should see SuperSU in your app drawer.
