Matcha Flashing the boot.img from inside the zip is exactly what I was recommending you to do.

The main change Scott made to recovery was he added the ability to use ADB from inside recovery. He did not make sideloading update zips possible, because recovery usually checks the signature verification of zip files.

However, since the zip here is official TCL, it may work to sideload it (likely has tcl signature). You can try to run from recovery:

adb reboot sideload
adb sideload update.zip ##replace with the zip filename

It's possible flashing Zips after rooting can have bad effects, although I don't think you'll have an issue because you already flashed back the stock boot image, and the zip itself had a boot.img. But I never tried this and I don't take responsibility for anything that might happen, although I expect it to go smoothly.

You didn't do anything else besides flashing Magisk's boot.img? The only other suggestion I can think of is doing a factory reset (via recovery), and turning on the phone without a sim card. But that's a random guess. If you flash back ALL the stock partitions (in other words, any partition you modified), you can also try fastboot flashing lock to relock the bootloader.

    Why is my device constantly being disconnected with "no emulators found"? and in phone settings "USB" becomes greyed out?

      Random tip. If anyone is looking for a good music player, i found that musicolet works really well. Its very small, plays multiple formats, and works mostly with the d pad. As per the faq it doesn't even request internet permission.

        Jumptoheaven Yeah, Musicolet is great. I've tried porting it to LG, but it uses a strong protection. I got close but the songs won't play.

        Anyways, yup, it's great.

          Biden2020prez how slow it is and how long it takes to load. Also it shows everything double

            I'm curious, if the issue with my phone was that it was on an older update and that was the issue with neutron's boot, could I install the update recovery? The only issue is I'd need to find a place to download the KEEZ update.

            Biden2020prez Just on a side note, did you figure out how to capture the files through adb while updating the phone?

              I am using neutronscott's ROM and I am trying to get voice access. I tried to install the apps4flip apk on it but adb gave me a signature error Failure [INSTALL_FAILED_SHARED_USER_INCOMPATIBLE: Reconciliation failed...: Reconcile failed: Package com.android.cts.apps.accessibility.voiceaccess has no signatures that match those in shared user com.google.android.apps.accessibility.voiceaccess.uid; ignoring!]
              I then tried an apk from APKMirror and APKPure and again I was unsuccessful. This time with a different error. Failure [INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113]
              Finally, I tried downloading voice access from the Aurora Store on my phone. After it was installed I opened it and a pop-up stated that I need to enable accessibility permissions. When I clicked "OK" it took me to a hidden accessibility setting page on the phone where it quickly scrolled down and all-of-a-sudden it closed up on me and returned to the home screen. I tried again and the same result took place with the phone telling me "Settings keeps stopping."
              I then tried to enable it through adb with the commands on the apps4flip website, but it to was to no avail. 🤔🤔🤔
              If there are any suggestions I am open with wide arms. 🤗
              Thanks

                oh, re-read a fews posts up and you talk about probably being able to install update from recovery. But as there is no response to that post yet, I guess no one has tried it. If I can be pointed to the update file I will try it and report back.

                My only other thought is to get a second phone, since it was only $20 and pull the firmware off it and put it on the unlocked phone, sort of like cloning one phone onto another. Not sure how to do that, but I'd be willing to try that if the update doesn't fix it. Then I'd have a backup phone in case I break mine, which I somehow do a lot (part of why I moved to a flip phone).

                  Reifam Yes. The apps4flip commands are not going to work. Use this app.

                  lgexalter1 I modified this accessibility manager too work on all devices (hopefully). [Login to see the link]
                  Remember you need to run adb shell pm grant com.android.cts.accessibility android.permission.WRITE_SECURE_SETTINGS
                  Works fine now on Alcatel TCL Flip 2 (T408DL)

                          I am having a bit of an issue. I downloaded it and it worked perfectly, but as a mistake, I set there to be a floating icon. So I tried messing with it and couldn't get it to open up voice settings. Next, I tried to delete it and reinstall it. I looked around on adb for the package name (with the "-3" filter option) and I saw two options com.android.cts.accessibility and com.google.android.apps.accessibility.voiceaccess I deleted both. After reinstalling the apk file I opened it and gave it permission, but then it didn't give me the option for voice access. I then went back to my computer and saw that only the first package was installed and not the second. Do you know why this happened and how to solve it?
                          -Thanks

                              phonesy But how would you extract the file?

                                Reifam com.android.cts.accessibility is the app i linked you to. just install voice access via ADB and you'll be fine. To open Voice Access Settings, just turn on voice access (for example, via notifications), and say "Voice Access Settings".

                                  Hi, does anyone have a way to export all the contacts to VCF via ADB, i used the command below but its not in VCF format, i can technically play around with it in Notepad ++ but i wanna know forst if anyone has a quicker way
                                  adb shell content query --uri content://com.android.contacts/data

                                    thanks for your response, but can you give me quick instructions on how to allow APK installations on this phone (TCL Flip) without wiping all the data on it?

                                        A) There's no such thing as quick instructions when it comes to this phone.
                                        B) I don’t think it’s possible to enable APK installation without wiping the data.
                                        C) Refer to the first post in this thread for more information.
