• Installing apps onto the NUU F4L

Has anyone had luck installing apps onto the NUU F4L? When I try downloading it through adb it always gives an error adb: failed to install launcher.apk: Failure [INSTALL_FAILED_INVALID_APK: YOU CAN'T INSTALL OTHER APP]
Does anyone know how to get around this problem? Thanks

    cjr hi, i was thinking of getting that phone, were you able to uninstall built-in apps (like the browser)?

        I personally have not tried to uninstall them, but you can access the developer mode by dialing *#777# and in adb you can see the files for the different apps, so I would assume you can delete it from there

              JKing2 Yes i was successful in uninstalling the browser (and any other app) on the nuu f4l.
              Ill try to be as clear as possible:
              First you have to enable debugging by dialing *#777# .....
              Then download adb....
              On adb type in "./adb devices" - make sure your device is connected.
              Next type in "./adb shell pm list packages"
              Find the package (app) you want to uninstall in our case with the browser, "com.android.browser"
              Enter "./adb shell pm uninstall --user 0 com.android.browser"
              This should uninstall the browser FOR THIS USER meaning it can technically be reinstalled but not very easily...
              Hope this helps you.

                    also to unlock your nuu f4l to diffrent services you call #NUNLOCK# then it asks for a password wich is supposed to be your IMEI , but when i put in my IMEI it says "password error" . what do i do ?

                    I tried installing an APK; got the error [INSTALL_FAILED_INVALID_APK: YOU CAN'T INSTALL OTHER APP]. Wondering if there's any way around this? Also, if you uninstall an app using adb, what would be the way to reinstall it, if necessary? Seemingly wouldn't be able to use regular adb route, otherwise you'd have the same issue as above.
