here is the situation with my Nexus 4:
* Android 5.0.1
* can't access via adb while in bootloader (I tried everything I found over the Internet... uninstall/reinstall driver, tried another port, another computer, another OS, etc.)
* device not recognized when I use the "ADB sideload" option of TWRP (In Windows device manager I see "Nexus 4" with a yellow mark but I haven't been able to find a driver for it)
I want to upgrade to Android 5.1.1 (and won't go further), but how?? since I can't do the OTA update (because of TWRP) and I can't flash the Google official image (since I can't access while in bootloader)...
I don't care if I need to wipe everything, my backups are up-to-date (nandroid + Titanium).
Does anyone has an idea?
I can access to my device from Windows via ADB commands only (not convenient but it works).
Thanks a lot.
