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&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

VeeKay

FliphoneBochur Can you explain better?
what is the bootloader and how do I lock or unlock?

FliphoneBochur

VeeKay I'm not exaclty sure where you're up to in regard to this phone, but if you've already flashed stuff to the phone, this may be the problem.
Fastboot is the mode you boot into with autobooter. With your phone off, run autobooter and plug it in. Once you're in fastboot, run fastboot flashing unlock and see if it fixes the issue.

VeeKay

FliphoneBochur I did this in beginning
now i;m doing it again it says < waiting for any device >

Biden2020prez

VeeKay Did you flash the vbmeta?

FliphoneBochur

VeeKay The phone is off and you're plugging it in when it's saying that?

VeeKay

Biden2020prez The files were in the folder I just followed the prompts in this post;
[Login to see the link]

VeeKay

Biden2020prez To be more specific just seeing now On the post mentioned I missed number 2. "Open the MTK Meta Tool that you downloaded above and select ‘Reboot Fastboot Mode’"
I realize now thats because I followed partially the instructions in the beginning of this post, that didn't mention anything about #2 in the post.
but I mixed the instructions of both.
What now?

VeeKay

what can maybe be done wrong is about the MTKMeta and Drivers, was anything supposed to be done with them?

Biden2020prez

VeeKay Don't follow that guide, its outdated. Try following Dartths guide on the top post here from start to finish.

also, are you on the latest software update?

VeeKay

Biden2020prez Not sure about the software it was brand new out of box not yet any service connected.
Now it's too late I cant access the phone.
I can try to start over again I hope it's gonna work.

Biden2020prez

VeeKay Yes try starting over again using the instructions here. It's actually good that you aren't on the newest update, which caused issues for some people.

Jumptoheaven

Biden2020prez what issues are you referring to?

Biden2020prez

Jumptoheaven Well, not exactly sure. [Login to see the link] mentioned to me in private that he bricked some phones when flashing certain partitions from a previous update to a phone with the newest update. Also, someone emailed me about bricking two phones when installing a kosher rom, and I suspected that maybe it was because he was on the newest update, but he never replied back to my email (so far)....

So I guess I am just not sure whether or not it's safe to flash the old super with new update.

(on a side note, the new update relocks the bootloader, which is a little strange).

darth

VeeKay It finally finished however after doing reboot< I see on my phone
Secure Boot Failure!
dm-verify corruption

Your device is corrupt.
It can't be trusted and may not work properly.
Press power button to continue.
or device will power off in 5 s

Doesn't look good, any idea?

Biden2020prez Try pressing the power button. The phone should then boot normally.

VeeKay

darth I tried that several times, also tried to start over but the same message pops up instead of asking permission to unlock bootloader.

VeeKay

FliphoneBochur I tried when was saying this, then took put the battery it should be off, still didn't help once I plug in it gets power and pops up this mesage.

FliphoneBochur

VeeKay Are you sure you're plugging the phone in while autobooter is running (dots should be poping up)? I had the same error before.

Biden2020prez

VeeKay Take out the battery for 60 seconds and put it back in and plug your POWERED OFF phone in when the autobooter dots are moving like FliphoneBochur said

VeeKay

Biden2020prez FliphoneBochur When I try to open the autobooter it closes right away, I initially followed someone's advice to plug the phone in first, only then it worked.

Biden2020prez

VeeKay plug in the phone, wait for TCL screen to show, then unplug the phone, run autobooter and plug in your POWERED OFF phone. If it closes right away, then open a command propmpt, in that folder and run autobooter and tell us what it says.

VeeKay

Biden2020prez Finally was able to get the autobooter but instead of asking permission the same previous message appears;
Secure Boot Failure!
dm-verify corruption

Your device is corrupt.
It can't be trusted and may not work properly.
Press power button to continue.
or device will power off in 5 s
