[snarldog]

Hi,all, I just get start with Nexus 5. can anybody tell me what the problem? follow with the command I input in windows shell.
K:\N5\ROOT>adb shell
shell@hammerhead:/ $ su
su
root@hammerhead:/ # mount -o remount system /system
mount -o remount system /system
mount: Permission denied
255|root@hammerhead:/ #

su
mount -o remount,rw /system

However this only works if you have a custom "insecure" kernel that allows adb to do root things.

Thanks for the reply!

So, I will write my story here, hopefully to help some other guy in the future!

Basically I was on debug build from AOSP for the N5! And I installed all proprietary files from Google, LG, Qualcomm etc! But camera was faulty! So I decided to flash the stock images from Google! Then I 've lost

adb root

So I flashed the boot image from the debug build I had previously!
adb root works like charm!

to flash it, I used: fastboot flash boot boot.img
