Those of you with rooted Fire TVs can now update your devices to software version 18.104.22.168, thanks to new pre-rooted ROMs created by Rbox. ROMs are available for the Fire TV 1, Fire TV 2, and now also for the Fire TV Stick 2, which was recently rooted for the first time. A ROM of this update for the Fire TV Stick 1 has not yet been released.
You can find the download links to these new ROMs at the top of the following XDA Forum threads: Fire TV 1, Fire TV 2, and Fire TV Stick 2. Please be sure to donate to Rbox to support him and thank him for continuing to keep all of our rooted devices updated.
Rbox has now added the Fire TV Stick 2 to his list of supported rooted devices. ROMs for both 22.214.171.124 and 126.96.36.199 are available. Calling these ROMs a “pre-rooted” ROM is not entirely accurate. The rooting method for the Fire TV Stick 2 uses Magisk to perform a systemless root of whatever ROM you install through TWRP, so Rbox’s ROM for the Fire TV Stick 2 does not actually contain the root access, like it does for other Fire TV models. The presence of Magisk means that you can technically install the stock 188.8.131.52 update from Amazon and still have a rooted device.
The advantage of using Rbox’s ROMs for the Fire TV Stick 2, instead of the stock update image, is that Rbox has added add-on.d support to the stock image. This means that changes you make to the OS should be preserved when installing Rbox’s ROM, whereas installing the stock image will wipe out all system changes every time it is flashed.
Use TWRP custom recovery, by following this guide, to install these ROMs on your rooted device. As always, these ROMs cannot be used to root your device. Your device must already be rooted to install these ROMs. To see if your device’s software version is rootable and how to root it, see my guide here.
The pre-rooted ROM for the Fire TV Stick 1 has now also been created by Rbox. Get it here.
