How to downgrade latest OTA update?

[echang01]

Hi, can you please provide some instructions on how to downgrade from the latest OTA firmware updates? I'd like to go back to my original firmware version when I bought the phone. Battery life and call functionality seemed more stable.

Hey @echang01,
Are you still experiencing issues with the battery life and call functionality?

Battery life seems to be ok but definitely not as good as when I first got the phone.

The call situation I'll need to assess and get back to you on
