Techgen still got this error
c:\adb\adb shell pm install -g c:/AppManagerLG.Apk
Error: Can't open non-file: c:/AppManagerLG.Apk
or
c:\adb\adb shell pm install -g c:\AppManagerLG.Apk
Error: Can't open non-file: c:AppManagerLG.Apk
I copied the file to (c🙂

      mg5077 after doing adb install -g try dragging the apk to the cmd prompt window, it should input the correct location. If it still doesnt work try it with a different apk (I dont know what a non file is, maybe theres something wrong with it)

          mg5077 You dont install with adb shell, just adb install -g

              mg5077 I had to study your post closely to find out what was going wrong 😉 . Its always a good idea to post exactly what it said including what you typed, It helps with the troubleshooting

                  Techgen now wen I have "finally" installed this app with -g its still there 2 permissions revoked REQUEST_INTSALL_PACKAGES and WRITE_SETTINGS I think that the second one is needed to be able to use this app for all good features
                  any idea ??!

                      Techgen mg5077 I think that the setedit app has root access you can download it from here lgexalter1 this is for sure that its have WRITE_SETTINGS permission

                              mg5077 Hmmm that's interesting. Seems like tracfone blocked it. Prob to prevent unauthorised carrier unlocking.

                                  Jumptoheaven Actually no, that's just Android's generally weird behavior about permissions.
                                  You need to use my settings app to grant these permissions that -g refuses to. I can sideload from LG File Manager now!

                                  And carrier unlocking is done within the modem firmware itself, and the process is backed by the RPMB partition.
                                  Unauthorized carrier unlocking is extremely hard on almost every device. All I can say to do is keep your Classic Flips for a year and have it on Auto Pay.
                                  Classic Flip works on AT&T, T-Mobile, and Verizon Tracfone SIMs
                                  I have mine on AT&T towers TracFone and it works perfectly. Maybe if your Tracfone brand supports GSM (ATT/TMO) SIM give that a try.

                                      mg5077 Jumptoheaven On the Classic Flip FASTBOOT is nuked. Doesn't exist in the ABOOT. And the Exalt is a device I don't know much about, but considering Verizon's track record, (and the US Unlocked Samsung S7 and up being bootloader locked and signed at VZ's request)
                                      I'm very likely to say it's got no FASTBOOT mode either, and if it does have it,
                                      "fastboot oem unlock" is 98% of the time nuked on VZW phones...

                                      However, holding END and Volume Down doesn't do anything but holding both, letting go of END, and pressing END again triggers a force factory reset. This is especially good for when you mess something up BAD and you can't get back out of it.

                                            xxdeafgirl true unlocking will be near impossible. was referring to recovery options.

                                              mg5077 I know, I was saying that others should post their problems like you did

                                                4 days later

                                                di2020 did you get any fix for your problem?
                                                I have 3 classics Which are stuck on the lg screen.
                                                I tried adb commands, different combinations of power and volume keys. Nothing is working. I have adb access on two phones but the package managers is unaccessible. cant seem to work fastboot or any other unbrick programs.
