accidentally formatted my karbonn a9+
i tried to hard rest my Karbonna9+ android phone. i pressed Power+volume+home button. after that there was an error displayed on the screen saying "ENTRY QPST DOWNLOAD". i quickly searched on the internet but wasnt able to find any successful link. but then my computer asked me to format the device, i thought this will reset my phone but unfortunately i was totally wrong. after the format i tried to start my phone again but nothing happened. i also tried different combinations of keys but all nothing happens not even a single pixel lit up lol. then i downloaded cherry mobile flare software and AIO flasher and all the image files and other files required. they didnt work for me too coz my laptop (windows 7, 64 bit) doesn't recognise the device (unknown device or Com5 error). i tried to flash it in fastboot in AIO flasher. it says flashing but nothing really happens even after 10-15 minutes. all the online forums i searched they say enable debugging mode on ur phone in order to reboot but i dont know how the heck i can do it when my phone doesnt even start up lol. I am left with a dead phone now. can anyone please help me out and solve my problem. and please advise me step by step what to do next in order to get my phone working please...
