[Nexus 9 Q&A, Help & Troubleshooting] Hum3rus:
Nexus 9 5.0.1 SkipSoft Android Toolkit (free) backup/restore bug?

I have a Nexus 9 running Android 5.0.1 bought from the play store. Just getting into hacking it, successfully used SkipSoft Unified Android Toolkit for Nexus 9 to 1.) install drivers (main menu, opt 1) 2.) backup apps and files (main menu, opt 2.1, 2.3) and finally, unlock and root the device (main, opt 3, 4). Now I am restoring my apps and trying to restore my files, and I have run into an issue. [Main menu, option 2.12 "Restore /data/media..."] works fine, takes me to the choice of detecting whether an insecure boot image is present. I have tried both options, to autodetect, or yes, it's there. Both produce the same end result, option 1 just takes a bit longer to get there because it is going through the detection process. A message is displayed, screen print is below, and it says, "(goto was unexpected at this time." before exiting to the main menu for device selection (NOT the menu for Nexus 9).

====================================================================================
This option will allow you to backup/restore part or all of your device.

NOTE: Apps backup will NOT save your SMS messages. If you want them backed up
select option 10 to install the Easy Backup and Restore app on your device.

VERY IMPORTANT: DO NOT TOUCH YOUR DEVICE WHILE ANY BACKUP IS BEING PERFORMED OR YOU
COULD CORRUPT THE BACKUP FILE.
====================================================================================

BACKUP OPTIONS
--------------

1. Backup ALL installed apps [full adb backup with options]
2. Backup Individual Packages ONLY [single app]

3. Backup selected storage folders [from Virtual SdCard, adb]

4. CWM NANDROID Backup [boot, cache, data, recovery, system]
5. TWRP NANDROID Backup [disabled, boot to custom recovery to backup system]

6. Pull /data folder [excluding /data/media] ONLY to your PC
7. Pull /system folder ONLY to your PC

8. Dump selected device Partitions to PC

9. Install Easy Backup and Restore APP [free] on your device [ADB Mode]

10. Install EFS Backup APP [free] on your device [ADB Mode]

------------------------------------------------------------------------------------

RESTORE OPTIONS [ALL OPTIONS REQUIRE ADB MODE]
----------------------------------------------

11. Restore apps from a Backup File [adb restore .bak file]

12. Restore /data/media [Internal Virtual SD Card] Backup

13. Restore CWM NANDROID backup [from option4] via CWM Recovery
14. Restore TWRP NANDROID backup [from option5] via TWRP Recovery

15. Back to Main Menu

====================================================================================

Make your choice:12

selecting option 12.

------------------------------------------------------------------------------------
For adb root commands to work your device needs to have an insecure boot image.

The Toolkit can check for the presence of an insecure boot image and if not found
the device will reboot to fastboot mode and boot one. This is not permanent and
your original boot image will be back on the next reboot.
------------------------------------------------------------------------------------

1. Automatically detect if boot image is insecure [recommended]

2. I am using an insecure boot image on my device

3. Back to Main Menu

------------------------------------------------------------------------------------

Make your choice [if not sure choose option 1]:1

Waiting for USB debugging to be enabled

Checking ro.secure on your device

Your adb status is set to Insecure

Your device has an insecure boot image present

The procedure will now continue..

(goto was unexpected at this time.

Here is where it exits to the device selection screen.

Not a huge deal, as I was able to copy some critical files back into the device's DCIM folder via Windows 7. Drivers seem ok, windows recognizes it as a Nexus 9, and the ***backup I did before unlocking*** REALLY SAVED MY ASS worked just as advertized. Only the restore option has an issue so far. Help?
