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

jessiesmith

darth
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..."

darth

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

Biden2020prez

darth or since it is windows path\to\super

jessiesmith

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.

Biden2020prez

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?

Biden2020prez

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"
[Login to see the link]
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?

Biden2020prez

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

My post is not missing anything. Please read it carefully. It is not for people with locked bootloaders.

jessiesmith Then I ran
fastboot reboot recovery

Phone screen shows "Android Fastboot", with several options.

I am assuming this is a typo or you don't remember correctly, you probably mean it shows "Android Recovery".

jessiesmith 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.

Correct, don't worry about those, they are recovery logs, not really errors (this is the other reason I am assuming you are in recovery and not Android Fastboot; Because Fastboot doesn't show those logs).

jessiesmith 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.

yes, the file path
/dev/block/by-name/super is very important, but not the file path to the super on your computer is okay for any valid super img.

jessiesmith I then ran
adb push super.bin /dev/block/by-name/super

You seem to have missed an important command (see my post you replied to - you need the chmod command).

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

It doesn't say your phone can't boot. It says that software cannot be trusted (as authentic factory images).

You have the option to press the power button to continue booting, or else it will turn off.

From my experience, sometimes I need to hold the power button for about a second, but not two long. Or try holding for 1 sec, let go, and hold for another sec. Then let go and wait, maybe it will boot up.

jessiesmith 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

Good, those are important.

jessiesmith Fastboot cannot access the device.

So probably you need to install fastboot drivers, check the link in [Login to see the link] original post. I repeat again that if you read my post, it explains that it is for updating roms, not installing for first time.

jessiesmith On phone, I clicked shutdown, it just show me a bunch of error messages and won't shutdown.

If I guess correctly it will shut down, but you need to be patient (and wait a few more seconds, then it will shut down).

jessiesmith 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.

Good luck!

darth I have the flip pro any options for me?
