Biden2020prez thanks, and thanks to everyone else who replied. I'll look in this thread for the voice access apk.
Something helpful for me with installing APKs for everyone else is the ADB App Control app for windows. I use it to debloat my big samsung phone and tablets, but found it very easy to use it to push apk's without having to use command line.

Biden2020prez SOLVED! I had to remove the spaces from the set command and do "set ANDROID_PRODUCT_OUT=C:\Android\platform-tools" instead of "set ANDROID_PRODUCT_OUT = C:\Android\platform-tools"!

Well, I got voice installed and it does some things when I ask it to. Have yet to figure out how to make it type in the messages text box yet, though.
Also, I tried using ADB to install vmouse2 via magisk, and it didn't give any errors afterwards, but magisk says no modules are installed, and holding any star key does not bring up the mouse. I feel so odd... I used to put Android Eclair on my windows mobile phone for fun back in the mid 2000s. And now I'm lost.
Is there a way to kill the constant notification for voice access, and get the untouchable button off my home screen?
[edit: figured most all this out, I'm good now}

Ah, I understand voice better now. Actually not concerned about mouse pointer nearly so much as voice puts a number on everything on screen and "touch [say the number, ie. 1] clicks it for me.
again, appreciate all the info from the devs and people who did the hard work on this!
Now, if I can figure out how to get emojis for text responses I'd be golden.

    I've seen a few people say that Android Auto isn't compatible with this OS. Has anyone figured out a workaround?

      Alright, thanks to you awesome people I have successfully rooted and have been able to do all kindsa stuff! (The app I'm most excited about having gotten working is Zepp Life, I didn't think I would be able to use my Mi Band with a flip phone!) However after messing around with my rooted flip for a couple days, there's a few things I just CANNOT figure out:

      1) Accessibility Settings crashes when it tries to load items #10 or #11. I don't know what those items are or whether this is fixable.

      2) How do I get the dang floating action button (FAB) to go away for Voice Access?? It's the bane of my existance right now to have it always floating over my screen when I'm not actively using Voice Access, like a stupid sticker I can't get off my screen!

      3) The apps4flip version of Button Mapper won't install, I get the error "adb: failed to install C:\Android\platform-tools\buttonmappera4f.apk: Failure [INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113]". I have no idea what library it wants. The latest version of Button Mapper I found on an APK website works though. (Version 3.09) But I can't remap any number keys with it because that's paywalled. I paid for the pro version on my smart phone, but can't activate the purchase on the Flip 2 because "billing not initialized". I really want to be able to remap the number keys to the installed apks in place of a launcher and to quick toggle settings.

      Any help or tips with any of these would be very appreciated!!

        lgexalter1 Ah, somehow I missed that in all my googling! I was able to make it a toggle with the volume key as well, awesome! Tysm!

        Biden2020prez This one, the one from Apps4Flip. I have no idea what #10 and #11 might be because it instantly crashes before scrolling to them.

            KEFH Update Warning:

            There is a new update out for this phone. Updating will relock the bootloader. If you modified the phone in any way the phone won't boot up unless you reunlock the bootloader. Unlocking the bootloader wipes all of your data. In short if you modified your phone and go through the update like you are supposed to then you are going to lose all of your data from your phone.

            I haven't gone through the new update but if anyone else has please share what the differences are. The calendar seems to be working and the recent calls is quicker (still not as good as it should be).

              darth if the phone is filtered with 1 of your Roms will it be able to download the new update?

                • darthLevel 6 - Platinum Elite Member

                  a-one No. I blocked over the air updates. Hopefully when I get around to it and when I see what is actually updated I will implement it into my Roms.

                    darth when flashing the first time 1 of your roms is it better to update the phone to this latest update or it won't be compatible with your ROM if it's updated to the latest update?

                      • darthLevel 6 - Platinum Elite Member

                        a-one There is no reason to update before hand. Once you flash my Rom you are undoing the update either way. But I have not tested it to know the compatibilitiy of it working after the latest update.
