Avoiding Android 10 update

[EMGSM]

How do you go back to Android 9 ? What are the steps to do that ?

Then Download Odin. This is the version I used (3v3.13.13B Patched)
Then I downloaded the firmware for my Note 10 model (Make sure you have the right model number). I got it from SamMobile. Put the phone in DOWNLOAD mode.
Once downloaded, unzip the firmware. You should see these files: AP, BL, CP, CSC, Home CSC as seen here:



These will go in their corresponding letters in Odin as seen here:



For the CSC tab on Odin you could choose CSC or Home CSC. CSC wipes all your data and basically starts from scratch. Home CSC updates the phone but keeps your data. When ready, connect phone to computer and hit start on Odin. Let the process run.

**Important note** Going up from android 9 to 10 Home CSC kept my data. Going down from 10 to 9 DIDN’T work for me and I had to do a factory reset. Again, make sure to back up data!!!
If you are not comfortable doing this the DO NOT try it.

Usually going from different Android version will lose data , Same Android version not issue.

You can downgrade from Android 10 to Android Pie since bootloaders are still the same.
