Got my hand-on repairing this Vivo Y91.
The phone just stuck in a bootloop "Vivo" Powered by Android screen
I managed to boot the phone into Fastboot Mode. Connect up with my PC and downloaded the Y91 firmware
Using the fastboot flash command to reflash the Android OS based on Funtouch 4.5
Phone successfully boot up.
"Command"
CD C:/adb
adb reboot bootloader
adb device
fastboot oem unlock
fastboot flash recovery PD1818 _EX_A_1.9.15.img
fastboot oem lock
fastboot reboot
