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 ).

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... 😆

dovwcom

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

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....

Biden2020prez downlead is unavailable

Flippy

Biden2020prez Run fastboot reboot fastboot, and wait for your phone to boot to the screen that says "Android Fastboot" among other information.

Any way for me to update the ROM if I am having the problem mentioned earlier, that my PC doesn't recognize when the device is rebooted into Fastboot, and still sayswaiting for device?

Biden2020prez

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.

Techgen

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

Apps4Flip-Admin

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

Techgen

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

chaimzalman

What happens when you initiate recovery mode?

Biden2020prez

chaimzalman Want to explain your question?

chaimzalman

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

Biden2020prez

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

Biden2020prez

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

Flippy

The download link for MTK Drivers is expired. Is this the correct one?
[Login to see the link]

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

Driver Auto Installer .1524
Driver Auto Installer .1612
Driver Auto Installer .1632
MTK Driver ext

Flippy

neutronscott I had trouble with that originally. I ended up installing one or two and getting it, but can we set the record straight?

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

Apps4Flip-Admin

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.

dovwcom

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

dovwcom

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?

darth

dovwcom I have also blocked: Software updates, Using public wifi. As far as video player thats included in gallery, I can block camera if people wanted, you can wipe or reset device but it wont change any of the settings in place. I dont think this phone has voice commands (and why would you want to block that?)

What else do people want blocked? Does anyone really want to blovk Camera or Bluetooth or Wallpaper? I can look into blocking hotspot and pin code.

If anyone has any other recommendations of what they want please let me know. I am not going to be making any ROMs with apps like Waze until I have an easy solution for activating the mouse.
