[Fire TV Android Development] kick60:
Hi folks, I had a Firestick 4k Fire OS 6.2.7.1 with Wolf Launcher and all was bliss. The OS got updated to 6.2.7.3 and that broke the Home button. I tried all I could find from scouring the XDA forums but nothing worked for me (accessibility apps, adb commands...) The Home key, as well as reboot, always return to the Amazon stock UI. I really miss the Home button returning to the Wolf launcher, as well as long-press of the Home button to get to Network settings because I often switch between my VPN router and normal router. Anyway, I got totally pissed at all the failed attempts and took a chance on rooting the Firestick 4K with Fire OS 6.2.7.3 to see what I could do. I hadn't seen anyone else mention that it could be done on 6.2.7.3, but I can indeed confirm that I was able to do it without issue following the very good 3 part video beginning with this->one (thank you Paul Jones), which begins by showing you how to dismantle the FS4K in order to short it and proceed with the unlocking of the device. It really was not that difficult. Now I have a rooted device with TWRP and Magisk installed and with many possibilities for customization.

I did delete the Amazon home screen (optional in video #3) and when I hit the Home button, it simply went to a blank screen. As I now have root access, with ES File Explorer I was then able to edit the keylayout file for the Amazon remote (/system/usr/keylayout/Vendor_0171_Product_0413.kl) to remap the HOME key to act as a BACK key and that solved that problem, but caused another. If the device went to sleep, I had to reboot the stick because the stock long-press Home button to get to Apps no longer worked. The fix to that was simply to disable sleep mode with ADB (settings put secure sleep_timeout 0). So now, I'm basically to where I was with 6.2.7.1 and the Wolf launcher booting up with the help of FTVLaunchX but now with root access. There's no more Amazon home screen or Amazon app store to get to, however I can still install Amazon apps via the Amazon website to my device. I can also install from a myriad of other sources like Aptoide TV, Downloader...

I still miss being able to long-press the Home button with the Wolf launcher in order to get to Network settings. I've tried all kinds of key mapping apps but none seem to work on Firestick 4K with OS 6.2.7.3. Does anyone know of a key mapping program that actually works with Firestick 4K OS 6.2.7.3? I run Button Mapper no problem on another Android TV OS device but Button Mapper installed on the FS4K does not recognize any key input from the FS4k remote. Its accessibility settings are setup properly but still no joy. Does anyone have Button Mapper working on a FS4k? If so, was there anything special required to get it working? Or, does anyone know where to map events based on key presses defined in the keylayout file?

Alternatively, does anyone know how to create a shortcut on the Wolf Launcher desktop that will allow me to map to the Network settings page? I think you can create shortcuts via ES File Explorer, but I don't know where the Network settings executable is. I know I can just get there with a few clicks via the new Fire TV settings icon, but that's no fun. It would be so much cooler to be able to create shortcuts to specific settings pages or whatever...

I also thought about some kind of wifi widget but the Wolf launcher doesn't allow widgets. ATV Launcher 1.5 does allow widgets but not sure if that works on FS4K.

Sorry for the long post but I'm eager to learn and would appreciate any help or suggestions.
