I downloaded a marshmallow update with amigo 3.5 UI for my gionee and upgraded it SPflash tool which worked out fine but i noticed that my phone started sending sms on its own to an unknown number. I asked my service provider about it and they said it's sending to an American number. So i decided to download another version (5.0, amigos 3.1) but that had a small issue, only one sim port was working.
i opened flash tool, clicked on format, selected auto flash and and format whole flash. After it finished flashing, my phone just went dead. Not coming up, non responsive, pc and flashtool can't detect it.
i have installed Android ADB interface, Amdroid Bootloader Interface, Android Composite ADB Interface.......Mediatek DA USB VCOM Port, Mediatek Preloader USB Vcom Port.
Please what exactly do i need to do to get my phone working? Thanks.
PS: phones plugged for charging.
