When I'm in bootloader I get:
daniel-levines-macbook:~ daniellevine$ cd Desktop
daniel-levines-macbookesktop daniellevine$ cd adb-fastboot
daniel-levines-macbook:adb-fastboot daniellevine$ ./adb devices
List of devices attached
daniel-levines-macbook:adb-fastboot daniellevine$ ~/desktop/adb-fastboot/ chmod +x flash-all.sh
-bash: /Users/daniellevine/desktop/adb-fastboot/: is a directory
daniel-levines-macbook:adb-fastboot daniellevine$
When my phone is on I get:
daniel-levines-macbook:adb-fastboot daniellevine$ ./adb devices
List of devices attached
0146B5040500C004 device
daniel-levines-macbook:adb-fastboot daniellevine$
I switched back and forth with USB debugging and tried different combos. Still no luck.
OK.so that number string is your phone when u adb devices
Adb recognizes your phone then.
Did.you try to
CD desktop
CD adb-fastboot
./ chmod +x etc???
Another thing is, your folders have to be named "adb-fastboot" for example, if its called something else you have to cd to whatever its called.
At dinner now, not sure when I'll be back but I'll try to be quick so I can help
