    Thank you [Login to see the link] for making this possible! Thank you [Login to see the link] and [Login to see the link] and [Login to see the link] and [Login to see the link] for helping me figure out different things about this phone. If anyone has any other ROMs they would like to add to this list please email me at [Login to see the link]

    Prerequisites: [Login to see the link], [Login to see the link], [Login to see the link], ([Login to see the link]), brains.

    Warning you are flashing custom firmware and can potentially brick your device! This process will delete everything on your device and there is no way around this! Make sure you are choosing a ROM that is for your specific device!

    1. Setup:

    1. Download and install all of the prerequisites listed above
    2. Download a ROM from the list below and extract the super.bin
    3. Download [Login to see the link] and extract them
    4. Place all your files in the ADB folder

    2. Unlocking bootloader and disabling AVB:

    1. Run Auto Booter
    2. Plug in your phone into the computer while it is powered off
    3. Once your phone screen says: =>FASTBOOT mode... on it run in adb: fastboot flashing unlock
    4. Press 'volume +' key to unlock the bootloader
    5. Once bootloader is unlocked run the following codes to disable avb:
      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

    2.5 Flash Boot.bin for Roms with apps that need a cursor

    1. Download [Login to see the link]:
    2. Run:fastboot flash boot boot.bin

    3. Flash Super

    1. While phone is still in fastboot mode run:
      fastboot reboot fastboot
    2. When the phone is back in fastbootd mode run:
      fastboot flash super super.bin (If you see "Invalid sparse file format at header magic" you can ignore it safely.)
    3. Once completed, to restart your device run: fastboot reboot

    You now have a kosher rom!

    Here are links to ROMS:
    THESE ROMS DO NOT ALLOW APP INSTALLATION (Even if you try the methods posted on the other thread!)
    Tested on t408dl, 4058E and 4058L:

    I will be posting more as I make them

    If you previously installed my mouse boot.img and you are updating to a newer version of my rom you should update to [Login to see the link] as it is the one that goes along with my updated rom.

    Helpful Tips:

    • To set up Voice Access:
      Go to notifications, activate VoiceAccess by clicking on the VoiceAccess notification, say: "Open voice Access Settings", once in settings you can go to 'configure activation key', then to 'activation key', click on the key you want to set (quick dial on back of phone or message shortcut), say: "touch ok", you should be all set!
      Also in settings you can toggle 'Activation button' to turn off the on screen button.
    • To toggle mouse press the favorites key (star icon). When mouse is on keys 7 and 9 scroll up, and keys * and # scroll down, key 3 opens options/right clicks. Once deactivated the mouse icon remains on screen for around 10 seconds.

      Updating Roms

      Here is a guide for updating Roms. This means you already installed one of darth Kosher Roms, and want to switch to a different one. If you follow these steps you shouldn't lose your data. This guide assumes you already did all the steps to install a kosher Rom, and you are working on the same computer (so you already installed mtk drivers, flashed vbmeta, unlocked bootloader, know how to use fastboot, etc)


      Step By Step Instructions:

      1. Download the rom of your choice from the top post on this thread (darth ). (make sure its named super.bin - I didn't check all them).

      2. You should probably download [Login to see the link] because you might have an old one. Run fastboot flash boot boot.bin to flash it.

      3. Run fastboot reboot fastboot, and wait for your phone to boot to the screen that says "Android Fastboot" among other information.

      4. Run fastboot flash super super.bin.

      5. When it finishes flashing super, run fastboot reboot, or press "reboot system now" on the phone.


      Great Job! All Done!

            darth Thanks, the more clear we can be on providing instructions, the less questions we'll have to field (hopefully). Too bad you can't provide a link to brains... 😆

                Techgen I don't think we should spend too much time on instructions because hopefully we will have a kosher firmware which will be preferable.

                    Biden2020prez True. BTW I just looked on Amazon, and it seems like its sold out 😦
                    EDIT: Just got one on ebay

                        Techgen A few frum cell phone store owners said they are going to start stocking up on the tcl flip 2 now that a good free kosher option looks doable. I’m not sure if that’s why Amazon’s out of stock but you never know.

                        I plan on working on a simple thorough guide for the main apps4flip site but I plan on waiting until we have the full kosher rom to do it so I don’t have to write the guide up twice

                            Yes. We are working on a way to allow Factory reset but keep browser removed.

                            Darth your link for drivers was removed because of violation of google drive terms. I had the same issue when i uploaded. Try putting it in a zip

                            Apps4Flip-Admin I was thinking the same.
                            Maybe it's better to keep it a little complicated in the meantime...

                                The download link for MTK Drivers is expired. Is this the correct one?

                                Once it extracts the folders, which is the correct one to install?

                                • Driver Auto Installer .1524
                                • Driver Auto Installer .1612
                                • Driver Auto Installer .1632

                                  darth I have regular Waze, Google Maps, 1Weather and WhatsApp with List Launcher from [Login to see the link] working on my Tracfone T408DL together with mouse toggle even after disconnecting phone from PC through grab as [Login to see the link] (as long as I don't reboot, keep the phone charged and have lockscreen disabled). My Browser and Email are suspended through adb as per OP.

                                  Note 1: I couldn't scroll up with the mouse nor do drag (for one time setup and settings Genymotion's scrcpy was very helpful because that worked fully on my apps)

                                  Note 2: a4fmouse.apk from the Apps4Flip site click on selections doesn't work for me

                                  Note 3: I want to install Google Voice and in order to get it working tried several ways to install Core Gapps zip (which I pushed to my SDcard) with Magisk but got errors on trying to add the module- in general should Magisk modules install on this neutron.img? Is there a way to get the Google prereqs working on this phone?

                                      dovwcom Note 2: a4fmouse.apk from the Apps4Flip site click on selections doesn't work for me

                                      the mouse doesn't work on android 11 phones

                                          ZTEGuy I know about that bug and nevertheless a) Genymotion's scrcpy works like a treat when I have the luxury of using adb and b) [Login to see the link] 's grab binary together with the script run as nohup to enable virtual mouse from the Quickdial works even untethered (not attached to PC) for the most part except that among other things it doesn't do scroll up so I tried to use a4fmouse.apk together with it because I knew that has an a4f scroll mode but it didn't work at all neither with [Login to see the link] 's script toggled nor without unlike scrcpy that just works regardless

                                            lgexalter1 changed the title to Instructions for installing a kosher ROM on TCL Flip2/Classic T408DL .

                                            darth I have read all of the massive TCL t408dl thread and additional material elsewhere on these forums and yet it's not at all clear to me what the phrase "Kosher" ROM means to you and others. To me the basic of being Kosher is that in addition to a default lack of browser, texting and internet based apps there is some level of security preventing ROM/app installation. In general and in the case of your ROM does that require additional MDM software? Please clarify....

                                              dovwcom In general removing with adb is not a great way to remove the browser and make a phone kosher. The best way to do it is to remount the system as read write and remove the actual browser and email apks. This way even if you reset the browser and email apps are still removed.

                                                  darth Apps4Flip-Admin I understand. So 2 questions:

                                                  1) Taking the features from the original FilterLG filter and applying them here I have marked the features that I understand are in your ROM with an x and left the rest with just a dash beforehand please comment if different:

                                                  FilterLG app basics
                                                  X Blocks internet access on the device (no browser even after reset)
                                                  x Blocks installing additional apps
                                                  – Blocks software updates
                                                  – Blocks ability to wipe/reset the device
                                                  – Blocks using device as a hotspot
                                                  – Blocks using a public wifi
                                                  – Blocks using voice commands
                                                  – Blocks setting a pin code on the device
                                                  – Blocks encrypting/decrypting the device
                                                  – Blocks Safe/Recovery/Download modes
                                                  – Enforced wallpaper on the device

                                                  Extras
                                                  x Block Email (even after reset)
                                                  x Block Text Messaging (even after reset)
                                                  X No Gallery (this feature in tcl408dl ROM and not filterlg)
                                                  – Block Video Player
                                                  – Block SD Card
                                                  – Block Camera
                                                  – Block Bluetooth

                                                  2) Would the FilterLG safely work on the TCL408dl out of the box?
