I fixed my problem using the adb from platform-tools. I'm not sure why that works, but it does.

Do anyone have the original, non-rooted firmware for T408DL that i can use to revert the phone back to its original state?

lgexalter1 i ment a firmware that has the file system unchanged because i was trying to remove root from this phone.

              I tried doing the filter but I got stuck by the part of typing the adb code because I didn't know how to go about it, can someone help me (the steps that needs to be done for this part)?

                Could someone help me I don't know how to what to do after I'm on fastboot mode when I want to type in ADB it says waiting for device I have the TracFone version and it's unlocked already (used it for 60 days with them)

                  Google 'how to use adb' there are many guides online. The basics are is that it is a command line/prompt program. You need to open command prompt or powershell on the directory where you have adb downloaded. Once there you run the commands.

                      And you need to write ./ before each command

                        darth I know how to use ADB I use it a lot but I don't know how to use fastboot properly. When I was in fastboot I typed in ADB fastboot flashing unlock and it said searching for device and it didn't show up any message on my phone screen.

                          fastboot is not adb fastboot

                            neutronscott when I'm on fastboot mode I can't use ADB it doesn't work and can't connect to my phone

                                a-one i had that issue in an old windows. Maybe 7

                                  meir you only need to do that in powershell. to use command prompt type CMD in the file path bar in the folder that adb is stored.

                                    mkw after opening the command prompt window, copy and paste the lines and hit enter after each line
