  • Instructions for installing a kosher ROM on TCL Flip2/Classic T408DL

darth is there any way that I can help you to help me with this? cant have the kids running around with a browser on these 4058W phone. Thanks! Also, is there a way for me to revert back to the factory ROM on this
"bad" kosher phone (I have another 4058W with factory ROM).

    will this guide work for the 4058g?

      does anyone know how to add an app to the rom before flashing it

          zlate The installation of these Roms deletes all installed apps.

            "Run Auto Booter".
            In command line, I ran mtkfastboot.exe, got error:
            Found MTK Preloader Port on COM4
            Running MTK Fastbooter on COM4
            ...............................................................
            b'READYTOO'
            Entered fastboot mode on port COM4
            Traceback (most recent call last):
            File "lion.py", line 97, in <module>
            AttributeError: 'Thread' object has no attribute 'success'
            [46576] Failed to execute script 'lion' due to unhandled exception!

            However, even with that error, when I plug in the phone, it did go into fastboot mode.

            I was able to proceed to run these commands:
            fastboot flashing unlock
            fastboot flash --disable-verity --disable-verification vbmeta vbmeta.bin
            fastboot flash --disable-verity --disable-verification vbmeta_system vbmeta_system.bin
            fastboot flash --disable-verity --disable-verification vbmeta_vendor vbmeta_vendor.bin
            fastboot flash boot boot.bin
            fastboot reboot fastboot

            BUT, the cmd window stuck at:
            Rebooting into fastboot OKAY [ 0.001s]
            < waiting for any device >

            On the phone, the screen shows
            [Login to see the link]

            Which option do I select? It does not matter which option I select, the CMD fastboot is stuck on < waiting for any device >

                jessiesmith Dont select any option. You are in the right place. Just close the cmd window and reopen it then run the commands to flash super.

                  Mine got up to 26%
                  Phone screen show: Write Data > 26% Time: xxxxxxx
                  After that, it took several minutes to progress to 27%, then it is taking a long time again

                  Remember, my mtkfastboot.exe error out on phone 1st boot, so the mtkfastboot.exe CMD window stopped.
                  Then, if I run mtkfastboot.exe again (in separate CMD window) and immediately run "fastboot reboot fastboot", phone will reboot into "=> FASTBOOT mode..."

                    • darthLevel 6 - Platinum Elite Member

                      jessiesmith Once phone is in "=> FASTBOOT mode..." then you should run fastboot reboot fastboot once the phone is in fastbootd like in the picture you shared then in a new CMD window (nothing to do with mtkfastboot.exe) run the command fastboot flash super /path/to/super

                        Got it flashed with one of the ROMs that have Waze.
                        When I open Waze, top screen just show "preparing navigation voice 0%", and stuck there. The map would not load.
                        I am somewhat new to this, maybe i need to post the question on other thread.
                        Also, I read there's a kosher app store, is it really possible to install the app store onto the phone, and then install other apps from the store directly intead of downloading the apk and manually loading it.

                          jessiesmith Not sure where you read that there is a kosher app store, but there isn't (last I checked).

                          Also this kosher rom blocks APK Installation so you wont be able to install any apps.

                            On Waze app, I could not get a GPS fix, error message "No GPS Reception".
                            Initially, I forgot to set the location on, so I did:
                            phone Menu -> Settings -> 5. Phone Settings -> 5. Location -> Set to On.

                            Restarted phone and restarted Waze several times, still can't get GPS working. I am outside with clear view of sky. No SIM card, but that shouldn't affect it, maybe just a slower GPS fix. On Wifi.

                            I read on forum posts people say to uninstall and reinstall it. But since this kosher ROM blocks APK installation, so I guess I couldn't do that.

                            Anyone have any ideas?

                              jessiesmith if I recall correctly, adb still works in the kosher rom (correct me if not). So dial *#*#33284#*#* to enable, then run adb shell pm clear com.waze, and let me know if that fixes it.

                              Alternatively, dial *#*#217703#*#*, go to MTK Non Framework LBS > Modify app location permission > permissions > use mouse to access search bar on top > search waze, open waze, click storage > clear data

                              the "Fast Method (first time)" does not work. It bricked the phone, after reboot, phone show "Secure Boot Failure! dm-verity corruptiopn"

                              Any way to rescue this?

                              Phone software version KEFH.

                              Details steps I took:
                              Open CMD, run mtkfastboot.exe
                              With phone OFF, connect phone to PC.
                              Phone screen will show "=> FASTBOOT mode..."

                              Open another CMD, run:

                              fastboot flashing unlock
                              fastboot flash recovery recovery2.img

                              I see your post is missing:
                              fastboot flashing unlock, I need to run this otherwise it won't let you flash recovery2.img

                              Then I ran
                              fastboot reboot recovery

                              Phone screen shows "Android Fastboot", with several options. On bottom of screen, I see a lot of error messages about "Invalid argument", "failed to format /cashe", etc. I ignored it b/c yesterday on another phone, I was able to continue even with those messages.

                              I then ran

                              adb push super.bin /dev/block/by-name/super

                              I used a different image name, but I don't think filename matters as long as the image is correct.
                              After that, the fastboot CMD window could not find the device, so I could not run fastboot reboot.
                              So on the phone, I clicked "Reboot system now".

                              After reboot, it show me the bricked screen "Secure Boot Failure! dm-verity corruptiopn"
                              [Login to see the link]

                              if I use CMD, run mtkfastboot.exe, the phone can still go to ""=> FASTBOOT mode..."
                              On another CMD, I did fastboot devices, and it show the device.
                              I then did:

                              fastboot flash recovery recovery2.img
                              fastboot reboot recovery

                              It will take me back to the bricked screen "Secure Boot Failure! dm-verity corruptiopn"
                              [Login to see the link]

                              I then removed battery, and put back in.
                              CMD run mtkfastboot.exe, the phone into PC, phone screen shows ""=> FASTBOOT mode..."
                              On another CMD, ran:
                              fastboot flashing unlock
                              On phone, Press "volume +" key to unlock.

                              Keep running these commands:

                              fastboot flash --disable-verity --disable-verification vbmeta vbmeta.bin
                              fastboot flash --disable-verity --disable-verification vbmeta_system vbmeta_system.bin
                              fastboot flash --disable-verity --disable-verification vbmeta_vendor vbmeta_vendor.bin
                              fastboot flash boot boot.bin
                              fastboot reboot fastboot

                              Rebooted, got the bricked screen, and phone kept rebooting a few times, I then disconnected USB cable. Now the phone is showing the Android Fastboot Menu:
                              [Login to see the link]
                              Fastboot cannot access the device.
                              On phone, I clicked shutdown, it just show me a bunch of error messages and won't shutdown.
                              I then removed battery to force shut off, then put battery back in.

                              CMD run mtkfastboot.exe, plug the phone into PC, phone screen shows ""=> FASTBOOT mode..."
                              On another CMD, ran:
                              fastboot flash super super.bin
                              Hopefully this will unbrick it.

                              Is there an original factory image somewhere for me to download? Is it the same steps to flash the factory image as the kosher images?
