Hello... sorry For annoying you.
I got the problem with my phone,,,(garminasus a50).
My phone got boot loop, because i got the mistake, delete some necessary file in sd card. I try to hard reset by hold left button of navigation during power on, but nothing happend.
I try to update during power on but fail (nothing happen).
I try to connect via adb for reboot recovery, I push top button of navigation during power on until show usb polling mode to communicate with my adb, but when I write adb devices in my command promt, no device found in adb. I already read all the instruction how to install adb.
I try to looking for the answer why my phone can not connect to adb, I have installed driver for my phone, in device manager already show adb boot loader interface.
Please lets me know, what is wrong, and what I have to do...???
Thanks so much if you want to respond my message....
