Now that we are able to modify the properties to allow installs, next step is to get a MDM based filter working on it!

    Apps4Flip-Admin What is a "MDM filter"? I am trying different things to make the new boot.img allow install without user intervention but I already tried to install a launcher from here and it was still not allowed. That is my next task, but [Login to see the link] reminded me of the key shortcuts can be set to any installed app so at least that gets things running.

      I decided to go with setting the ro.vendor.tct.endurance variable in a custom.rc.

      on init
  setprop neutron.build 2022-09-01T00:10
on post-fs-data
  exec u:r:magisk:s0 root root -- ${MAGISKTMP}/magisk resetprop -n ro.vendor.tct.endurance true

      Same URL but I kept the old img that ran the shell script every 5 sec as neutron-debug

      This is built with Magisk-v25.2.apk

      Instructions are something like --

      1. Open [Login to see the link] and select "Reboot Fastboot Mode"
      2. Plug in powered off flip phone
      3. fastboot flashing unlock
      4. fastboot flash boot neutron.img
      5. fastboot reboot
      6. Dial *#*#DEBUG#*#* to enable adb (optional)
      7. adb install magisk.apk (optional - can do online download later)
      8. Menu > Settings > Phone Settings > Key shortcuts
      9. Change left or right key to Magisk and select Save (If not an option, reboot once more)
      10. Launch Magisk
      11. Run adb shell and su!
        EDIT: You need to reboot once for the magisk.db to be created and to keep your Grant saved

      To remove write protection on emmc partitions in normal boot run /vendor/bin/write_protect 0

        neutronscott Great work! An MDM filter is something that allows a user to block access to specific apps. A lot of users in this community use it to prevent there flip phone from having internet access, hence the reference here.

        We would love to post these instructions on our main site with a link to your image. Are you ok with us doing that? What name would you want us to list as credit for this?

            I realized the Magisk popup was because the patched.img was built with 25201 so I recreated it with the release version v25.2 (25200). Now I'll leave it alone for awhile.

              neutronscott Do you need to install magisk with adb? Once your boot.img changed the props to allow for installation Im pretty sure the stub is installed already automatically and can be accessed using the settings>phonesettings>keyshortcuts
              Also do you need to enable OEM unlocking before unlocking bootloader?

                    Im working on a zip with very basic instructions and all that is needed for app installation on this phone (ADB, MTKmeta, [Login to see the link] boot.img).

                      KCO mouse has the selecting glitch. Button mapper is not able to use the star and message and sos buttons.

                      darth Do you need to install magisk with adb?

                      Oh I didn't know. I just quickly tested after a factory reset and it did show up after a reboot, then after I setup wifi it installed after enabling magisk to install apps. So that way works fine too I just didn't have WiFi setup yet and didn't try rebooting. Perhaps the rc could be modified so that reboot isn't necessary.. I'll check it out tomorrow.

                      darth Also do you need to enable OEM unlocking before unlocking bootloader?

                      No. I never entered that menu on this phone.

                            neutronscott very impressive work you did, You've managed to circumvent the restrictions of this device, meaning you can install apks on this device.

                                      Is there any way to permanently uninstall the browser? (Even though I have root its still read-only...)
