Hi Everyone, this is Nestor Jon of Fix and More

Disclaimer: This downgrading was tested working 100%. This is the same process as downgrading other Xperia phones. Follow instructions very well. I'm not responsible for any software or hardware brick on your device.

Important!
Back up your important files before downgrading. Everything in the internal storage will be deleted in flashing.

I'm here to help. If you have any questions, drop down your comments below and I will answer them as quickly as I can. Please don't forget to hit like, and sub to my channel. There would be future uploads.
