vaibhav bhai, you are missing something here

when you use volume key+power key to get to recovery it shows no command

at this point you have to press either of the voume keys again(or maybe it was the power key , cant remember right now) to get into recovery, where you can do factory reset

its a two step process to reach there. i have tried this on lenovo s920 & p780 both first reach the no command page.

If just pressing the volume key does not help,try pressing power Button and both volume keys together. Means all three pressed. And then release the power key while still holding on to volume buttons. As soon as u release the power button u may find yourself in recovery

[vabs 81]

Babaji, yes u were right after pressing power key it got into recovery..

Yes Dave thanks a lot but needed some try

Now friends already in recovery wiped catche and kept it for factory reset ... Don't know how much time it will take already 1 hr pass

Removed both sim and SD card before doing all this.

Thanks a lot babaji n Dave

[vabs 81]

Update : managed to factory reset it but still stuck up at lenovo logo at start, no animation or any activity.. looked like bricked phone.

now searching for India specific stock ROM for 8GB model .. strangely its not easily available. any pointers would help

[::: VA ::: 531]

Why don't you try need ROM?

They have official and custom ROMs for this phone.

For e.g.

SK your ROM and flash tool are perfect but i am getting problem with MTK preloader Com USB drivers

tried many solutions including xda methods to install it but nothing is getting work out ..

may be i am missing some steps./ or doing wrong or something with my system (feeling stupid)

- cleard all USB and driver entry with USBDview, also cleaned the registry

- then once it showed but gones in seconds before i can run the flash tool

- then back to same route cleaning and reinstalling drivers .. but still no luck

will try today one more time then give up and head over to service station
