Rbox has just released pre-rooted ROMs of the new 188.8.131.52 software update for the 1st and 2nd generation Fire TV, as well as the 1st generation Fire TV Stick. If your device is already rooted and running a custom recovery, you can now update to the latest software version without losing root access.
As always, I captured the update packages for all three devices and sent them over to rbox for ROM creation. These ROMs are identical to the stock updates except they’ve been pre-rooted so you don’t lose root access when you install them, like you would if installing the over-the-air stock update. Be sure to donate to rbox if you can to thank him for continuing to keep all of our rooted devices updated.
Download the latest ROMs from the usual XDA forum threads found here: Fire TV 1, Fire TV 2, and Fire TV Stick 1. Use TWRP custom recovery, by following this guide, to install these ROMs on your rooted device. Fire TV Stick 1 owners may need to refer to this guide to be reminded how to get into and control TWRP using a PC.
Your support through Patreon makes it possible for me to capture these updates for rbox and keep all my guides up to date.
