for once i thought it's gone "usb not recognised error, no device detected on sp flashtool"
but thanx to your reset button method
m back again

This goes out to all others who face problems flashing chinese phones with MEDIATEK BASED PROCESSORS and also maybe most of other chineese phones.. i had another difficulty flashing a a JIAYU Phone and flashing procedure didn't work according to plan. I tried various techniques but didnt work. Something came to my mind from expeirence with other big telecom chineese vendor software WINDOWS VISTA, 7 & 8 are not good operating systems for the Chineese hardware .. the driver software normally have issue..


So i installed a fresh Windows XP on my machine (DUAL BOOT) and that worked easy.. drivers detected .. flashing went smooth. If your thinking of installing XP as a Virtual Machine... good luck to you... im sure if it would work.. come post here

Best solution: go to a service store with the phone. From what you tell us this seems to be a motherboard problem.

Same Problem
Same here... the phone freeze and black screen leaving only red led ... can't figure out why ... going to service center will cost almost half of the current sell price ... so i'll try alternate workaround if any thanks

I have flashed ROM in devies 2-3 time. It works fine for 2-3 hours then suddenly screen goes off. Reset button will also not work. Then have to open handset and remove battery connector , then its getting started normally then again suddenly screen goes off.
I have changed battery also. Any more ideas guys?
