When a device powers on, the bootloader first checks if a device is LOCKED or UNLOCKED. If a device is UNLOCKED, the bootloader shows the user a warning and then proceeds to boot even if the loaded OS isn't signed by the root of trust.

If the device is LOCKED, the bootloader goes through the steps in Verifying Boot to verify the device's software. LOCKED devices boot only if the loaded OS is properly signed by the root of trust. For more details, see The boot flow.

After much fighting to get into fastboot mode, it works on the T-Mobile variant. Kills software update though.

I cant help but acknowledge the amazing talent of the people of this community, your efforts and achievements are so dazzling, people like you are helping the frum world in a way not everyone can. I know I'm disturbing the tech talk, but everyone should know that you guys are amazing!! I own one of these phones and I cant use it cuz I never knew how to kasher it, plus no apps is not so convenient, but I'm reading this thread and I'm seeing that there are some wickedly talented tech savvy special people who are devoting their precious time to help the klal by broadening kosher flip phone options. I cant wait for this to wrap up, Keep Going And Be Blessed!!

lgexalter1 so far I've only had success doing it on the phone itself with magiskboot, which takes a bit of time to repack. I work out of /data/local/tmp:

/data/data/com.topjohnwu.magisk/lib/libmagiskboot.so unpack boot.img
/data/data/com.topjohnwu.magisk/lib/libmagiskboot.so cpio ramdisk.cpio 'add 0700 overlay.d/custom.rc custom.rc'
/data/data/com.topjohnwu.magisk/lib/libmagiskboot.so repack boot.img neutron.img

if you're messing with super I did get it open using lpunpack. Not sure where that came from though...

        neutronscott that explains why my images wouldn't get repacked correctly when I tried working with an overlay. thanks for this

            Why is 'Modules' greyed out in my magisk app? Also when I try running Gflip6_TF:/ # magisk --install-module terminaldebloater-v5.1.zip I get: Incomplete Magisk install?
            Would terminal debloater work to uninstall the browser?

              darth go to settings and enable zygote or whatever and reboot

                Hi everyone! I am in yeshiva and cannot really be involved in this now. I just want to say, I am keeping updated on your guys' project and I'm really excited.

                [Login to see the link] You're really amazing. We're so glad you made your way to these forums, and we all owe you a big thanks!

                  Is this the same as the Alcatel My flip 2? Because that seems to run Kai OS...

                    EnriqueMcquade There was a patch in android 11 that accidentally broke virtual mouses. The patch seems useless for flip phones anyway, i don't know how we would disable it though. If i have a chance, ill try to research more about the patch and see what needs to be done to fix it.

                      EnriqueMcquade Are you guys still working on the custom recovery?

                      I was hoping to quickly enable adb in the recovery img but not really sure what to do with this:

                      C:\Users\m\Downloads\mtk>adb shell
adbd F 09-03 18:47:05   311   311 shell_service.cpp:380] Could not set SELinux context for subprocess
libc: Fatal signal 6 (SIGABRT), code -1 (SI_QUEUE) in tid 311 (adbd), pid 311 (adbd)

                        darth I read through the instructions and that doesn't seem to address the problem with these partitions. This removed the "shared_blocks" feature, which we don't have:

                        Gflip6_TF:/data/local/tmp # tune2fs -l /dev/block/dm-2 | grep -e vol -e feat
Filesystem volume name:   /
Filesystem features:      ext_attr dir_index filetype extent sparse_super large_file huge_file uninit_bg dir_nlink extra_isize
