yeti Sorry I looked back at the code and it checks for "userdebug" not "eng"

Also Magisk comes with resetprop. [Login to see the link] can you use resetprop to set ro.vendor.tct.endurance to true or ro.build.type to userdebug

      lgexalter1 I don't have additional steps. So anyway how the error looked like. It might be an incompatibility with the boot image I've provided to you because this boot.img is presumably tied to the T408DL.

        EnriqueMcquade you mean it has an error or does it not set the property? After you set these you can try an apk install?

          lgexalter1 I've heard that there are slight differences between the walmart family mobile t408dl and the tracfone t408dl. Which one do you guys have?

            In fact, I have a Walmart Family Mobile version of the T408DL. Which I got from a local Walmart Supercenter in Georgia.

            If the image is compatible with the T408DL, maybe I slightly made an error making the image or what could be possibility go wrong with such image?

            It looks like the patched boot img doesn't boot with tracfone, only walmart family mobile

            My phone arrives tomorrow night hopefully. I made an attempt at writing a quick custom script that runs on boot using the patched.img that darth posted. It polls /data/local/tmp for *.sh files every 5 sec. It writes a .out file and skips .sh which already have a .out. Hopefully all running as root. If it works you should be able to do something like:

            cd /data/local/tmp
cat >1.sh <<EOF
resetprop ro.vendor.tct.endurance true
resetprop ro.build.type userdebug
EOF

            Wait 5 sec and check the properties...

            Maybe I uploaded the wrong one. My phone just arrived and I've lots of ideas so hopefully tonight after work one of them works for us.

            I've uploaded the new image in the same place if anyone wants to play with it. It just runs a script that looks for scripts in /data/local/tmp/*.sh that it will run as root.

                neutronscott Your img booted fine but when trying to run su it still says Permission denied. And in /data/local/tmp there are no .sh files all thats showing is: mtk-su myscript.out. Am I supposed to be doing something to make your script run?

                    lgexalter1 I tried pushing a basic script and got the following errors: resetprop: __system_properties_init error
                    resetprop: __system_properties_init error                     which is the same error it throws when I try using resetprop in adb. (Thanx for asking around for a magisk exploit 😉 )

                        lgexalter1 Interesting... adb shell getprop ro.build.type returns userdebug andadb shell getprop ro.vendor.tct.endurance returns a blank line, in fact it seems there is no prop ro.vendor.tct.endurance.

                          I made it as a way to test things as root until more is discovered. For example:

                          Gflip6_TF:/data/local/tmp $ echo 'cat /vendor/build.prop' > 3.sh; sleep 5; cat 3.out | head
