"Your device didn't start up successfully. Boot failure because of the unsigned OS image. Please contact custom service to recover the device. Press power key to shut down device"
Any help will be greatly appreciated.
I can't find a way to get into recovery but when I press and hold volume down and power button, it says "Booting into recovery" then later takes me to the startup screen with the above message.
I can boot into fastboot. Kindly upload any firmware or recovery that can be flashed through fastboot. Or advice how I can put my device into working order.
