Thanks so much.
With a lot of help, guide & resourceful materials U hv here, my TECNO R7 is up and running.
I wz able to flash cwm recovery using pdanet & mtk droidtoolz and it worked.
Sp flash didn't work for me, but pdanet did.
For it to recognise d phone, I had to put it in factory mode, according to ur guide, and d phone was recognised.
Rooting d phone again was quite easy bcos I had SU already installed.
After d backup, d boot and recovery didn't quite work, bcos I was trying to use d 3rd option thr. I also tried d 2nd option, stil didn't work. It kept telling me dat Recovery didn't suit d phone. I later tried d 1st option, supplied d boot.img & d recovery.img wen asked for it, and viola, it worked.
Super big thanks to the Hovatek team for helping to ressurect my R7.
