android - LG G4 not seen/recognized by ADB -


i can't lg g4 phone show in adb on windows 10 desktop machine - no devices found running "adb devices" or "adb usb" in cmd or checking android studio's device manager tab.

things i've tried:

  • i've toggled usb debugging mode
  • i've rebooted phone , pc
  • i've installed, uninstalled, , reinstalled following drivers in every permutation/combination/etc:
    • lg's driver (lgmobiledriver_whql_ver_4.2.0 , version 4.0.4)
    • google usb driver (via android studio); note, don't see changes whatsoever system when install/uninstall this, i'm not sure it's doing
    • universaladbdriversetup6
    • whatever windows keeps installing automatically
  • i've tried charge mode / mtp mode / ptp mode. of time leave in ptp mode because seems other posts say, hasn't made difference me.
  • i've tried different usb ports on desktop
  • i've tried "adb kill-server / start-server"
  • i've tried "adb devices / usb"
  • i've unplugged/plugged in phone repeatedly

so far, nothing gets adb see it.

further details:

  • whatever drivers have installed, ever see (under device manager) subset of following:
    • android device > android sooner single adb interface
    • android device > lge mobile adb interface
    • portable devices > g4 (with blue phone icon or gray phone icon, depending on if have lg's provided driver installed)
    • universal serial bus devices > adb interface
  • there no "unknown" / "other" fields under device manager, if uninstall drivers
  • there no yellow triangle warning icons in device manager
  • i have automatic driver updates turned off (it on before, turned off make sure wasn't automatic function breaking things)
    • this doesn't stop windows automatically doing whatever automatically when plug in device - auto-installs kind of basic driver if i've deleted else

note:

  • despite looks like, question not duplicate, other similar questions i've found either outdated or marked resolved "solution" didn't work me (which got of failed attempts listed above)
  • i have laptop (the above attempts on desktop), running windows 10. adb sees phone; however, once see phone, fastboot can't see phone. if happens desktop too, i'll make separate question, meanwhile goal phone showing on desktop's adb.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
