New pre-rooted ROMs of the latest 188.8.131.52 software version have just been released by Rbox. Those of you with already rooted Fire TVs and Fire TV Sticks can now update your devices to the latest software version without losing root access.
To download the new ROMs, head over to the XDA Forum page for your device, found at the following links: Fire TV 1, Fire TV 2, and Fire TV Stick 1. Be sure to donate to Rbox to thank him for continuing to keep all of our rooted devices updated. If you appreciate my contribution of capturing the stock images that I passed to Rbox for him to use for these ROMs, you can support me through Patreon.
It’s safe to update directly to these new 184.108.40.206 ROMs regardless of what software version is currently on your device. You do not need to install previous updates before installing this latest one. 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.
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 is rootable, see my guide here.
