In My Raspberry Pi 3 B - just i have loaded the OSMC and it is working good, but when i try to entering the Password in the My OSMC menu page, it get freeze and start blinking the Red LED, I have been cycling the RPI power 3 times and the same problem I am facing always, now I am using the 5v, 2.5 amps smart phone power supply.
What could be reason for this issue, pls suggest for the possible solution
A smart phone power supply is usually a simple charger. Chargers are not designed to give a stable voltage under load, which the Raspberry Pi most definitely needs.
The official Raspberry Pi power supply works well, and the OSMC store also has a suitable power supply.
