title: Downgrading Firmware (3.65)
|
|
sidebar: false
|

|
|
|
### Required Reading
|
|
|
|
If your device was unable to downgrade to firmware version 3.60 due to its "factory firmware", you will still be able to use the more convenience Ensō boot-time exploit (as long as your "factory firmware" is 3.65 or lower) by downgrading to firmware version 3.65.
|
|
|
|
Unfortunately, you may experience minor software incompatibilities as you will not be able to use any homebrew which is only compatible with 3.60.
|
|
|
|
::: tip
|
|
Ensure your device has a battery charge of 50% or greater before proceeding.
