Thank you @neutronscott for making this possible! Thank you @lgexalter1 and @Biden2020prez and @yeti and @sdmde 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 t408dl@gmail.com Prerequisites: ADB , Auto Booter , MTK Drivers , ( Fastboot Drivers ), 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: Download and install all of the prerequisites listed above Download a ROM from the list below and extract the super.bin Download VBmeta files and extract them Place all your files in the ADB folder 2. Unlocking bootloader and disabling AVB: Run Auto Booter Plug in your phone into the computer while it is powered off Once your phone screen says: =>FASTBOOT mode... on it run in adb: fastboot flashing unlock Press 'volume +' key to unlock the bootloader 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 Download this boot.bin : Run: fastboot flash boot boot.bin 3. Flash Super While phone is still in fastboot mode run: fastboot reboot fastboot 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.) 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: Talk Only Removes: Browser, Texting, Email, Gallery, Camera, Music, Recorder. Talk Only-Basic : Removes: Browser, Texting, Email, Video. Talk Only-With Apps Op 3 : Removes: Texting, Browser, Video , Email, and Hotspot. Includes: Waze, Weather, and Siddur. Talk&Text : Removes: Browser and Email. Includes: Voice Access. Talk&Text-NO Video : Removes: Browser, Video, and Email. Includes: Voice Access. Talk&Text-With Apps Op 1 : Removes: Browser, Video, Email, and Hotspot. Includes: Waze, Weather, and Siddur. Talk&Text-With Apps Op 2 : Removes: Browser. Includes: Waze, Weather, Siddur, and Hotspot. 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 this boot.img 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: 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). You should probably download this boot.bin because you might have an old one. Run fastboot flash boot boot.bin to flash it. Run fastboot reboot fastboot , and wait for your phone to boot to the screen that says "Android Fastboot" among other information. Run fastboot flash super super.bin . 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

What happens when you initiate recovery mode?

chaimzalman Want to explain your question?

Biden2020prez if you remove the browser you can still reset the phone?

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

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

joe1234

Biden2020prez I did that, took the 45 minutes, and it worked! Thanks!

littlebob

i have been trying to install the kosher rom. Im getting stuck at #2 part 4 "Press 'volume +' key to unlock the bootloader." After i do step 3 "Press 'volume +' key to unlock the bootloader" it says waiting for device, i press volume up on the phone and nothing happens. any ideas? i have tried several cords that work for connecting the phone to the computer for transfering files.

fried

any updates also on the other roms? thanks

NEC

Biden2020prez i tried running fastboot reboot fastboot, but i get a response fastboot: usage: unknown reboot target fastboot. anything i'm doing wrong?

Biden2020prez

NEC Maybe you have an old platform tools. Get the newest fastboot exe [Login to see the link]. Your phone isn't filtered, right?

NEC

Biden2020prez i am having the same problem. tried a new cable still have the same problem

NEC

Biden2020prez it worked but now i got waiting for any device. tried new cable nothing doing. any ideas?

NEC

Biden2020prez what was the way to do it through recovery?

Biden2020prez

NEC Yeah. if the phone rebooted the the fastboot with the ,enu, open a new command prompt and do the rest of the commands

NEC

Biden2020prez i tried. when i hit enter it said waiting forv any device again.

Biden2020prez

NEC

_> autobooter.exe      # These instructions assume you already flashed vbmeta and unlocked your bootloader 
_> fastboot flash recovery recovery2.img 
_> fastboot reboot recovery
_> adb shell
$ su
# chmod a+rw /dev/block/by-name/super
# exit
$ exit
_> adb push -p super.bin /dev/block/by-name/super

Biden2020prez

Flippy use this older method

Biden2020prez

NEC

thank you that worked!

Biden2020prez

NEC Okay glad it worked

shaztzi

anyone else cant open adb.exe? its extracted already...

whynot

shaztzi you don’t open adb.exe, you open the folder it’s in and on the bar on top (where it shows the file path) you delete the file path and type cmd and hit enter. That should open a command prompt.

johnf

how do you stop someone from unkoshing a phone after it is koshered. How do you make it permanent

darth

johnf Short answer: Go to TAG.

johnf

The ROM installation page is labeled T804DL and not T408DL - just a typo needs to be fixed.

Reifam

darth Do you know how they make their filters permanent?
