adb backup woes: UT 14, Nexus 5

circ

# adb backup -apk -obb -shared -all -f ./current.ab

adb prompts me to unlock the device with:

Now unlock your device and confirm the backup operation...

Device never prompts, backup never starts (55b ./current.ab is created)
Do I need to reboot to bootloader first and do something I don't know what? (backup when in bootloader fails)

@circ Developer mode is on yes? You granted access to the phone via the pop up box then sudo fastboot OEM unlock.
But I thought nexus 5 was unlocked might be wrong though.

circ

@lakotaubp thanks, yes - OEM unlock was an install step.
adb devices
shows the N5

I can do things like adb push myfile.txt /home/phablet/Downloads without issue

circ

so, here's some fun ->

> adb version
#Android Debug Bridge version 1.0.36
#Revision 1:7.0.0+r33-2
> adb backup -these are not any kind of acceptable params ....
Now unlock your device and confirm the backup operation...
>

that adb backup cmd is verbatim...
Where do I go to get help with this? I'm on pureOS (debian)

circ

... and after a direct grab of the toolkit here : https://developer.android.com/studio/releases/platform-tools

> ~/Downloads/src/platform-tools/adb version
#Android Debug Bridge version 1.0.40
#Version 4986621
> ~/Downloads/src/platform-tools/adb backup totalgarbageandN0nS3nse
Now unlock your device and confirm the backup operation...

which is the same 'error'
..so, I'm guessing it's definitely a UBports / this particular phone/install related issue....

If you want a full system back-up via ADB, you need to do it via recovery, not developer mode in the running OS.

thanks, yes - this is all happening in recovery mode :

> adb devices
List of devices attached
0b3a1eb703301be3	recovery

Ah, I don't think adb backup works with UT, because it's not an Android ROM, and that feature only works with Android.

You need to adb pull /data/*-data or something like that. I forget the exact command.
