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

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

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.

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 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.

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.

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

Hi,
Thank you for all the hard work. I Updated from a Canadian Phone 4058E and was able to install Talk&Text-With Apps Op 2. However, I lost the ability to Import/Export Contact, and also I used to have the option to turn on VoLTE (This is needed for canadians traveling to the US) and this menu option is not there anymore

How can I remove/disable the cursor?

C:\Users\Home\Downloads\platform-tools_r34.0.1-windows\platform-tools>fastboot flash super super.img
Sending sparse 'super' 1/13 (130960 KB) OKAY [ 12.817s]
Writing 'super' FAILED (remote: 'CHUNK_TYPE_FILL flash write failure')
fastboot: error: Command failed

What do I do phone will not turn on either

Yehudi Did you do anything before these steps? is this a 16GB TCL?

Biden2020prez yes was updating the no browser kosher rom from 1.1 to 1.2 and it got stuck by like 6/13 then I kept retrying
phone goes into fastboot mode and into bootloader menu also phone keeps trying to go on but powercycles itsef all that comes on is TCL in red

darth so 1.1 worked some of the family phones had some issues so i updated all except this one got a error by 6/13 I think possible the wire got pulled on this device

fastboot reboot fastboot just takes me to a bootloader screen but then the device is not communicating with cmd

darth did not modify recovery followed your instructions exactly
and left the phone attached for hrs. then got failed message
