We warn you against proceeding with the single file installation method as described below.However, if you are to downgrade to a lower version of Gingerbread from a higher version of GB ( from Android 2.3.7 to 2.3.3, for example), you can follow this tutorial.
In my video I use my computer to share its internet connection with the Fire TV Stick so that I have full control of the connection. Instead, you can use your routers settings to stop the connection, or even just pull the power to your modem or router. You can try to follow this method without blocking updates, but be aware that the Fire TV Stick continues to try downloading updates in the background, even after you pass the “Checking for Updates” screen.
We are always eager to upgrade our phone to the latest version so that we might enjoy the new features and apps that come with a new update.
All the same, I would like to warn you that Those willing to downgrade their Galaxy device to Gingerbread from Ice Cream Sandwich or Jelly Bean should not follow the method given here unless you have the firmware files with Bootloader or PIT.
In case you have a PIT file for your device model, select it while installing the firmware and do not forget to check on Odin.
How to Reduce Lag and Make Touch Wiz Faster without Rooting How to Get Your Preferred Language on Your Galaxy Phone or Tablet Please note that the method described here has been tested (by me, more than once) on Galaxy S4 (Android 4.2.2), Galaxy S3 (Android 4.1.2 to ICS), Note 2 (Android 4.1.2 to 4.1.1) and Galaxy S2 (ICS to GB).
I have not been able to test for downgrading to GB from JB.
If you are blocking updates, the Fire TV Stick will not allow you to complete the initial setup.
The video above and instructions below will show you how to get past the forced update in order to complete the initial setup without updating.
If your Fire TV Stick is running a newer software version, this method may not work for you.
