Introduction

 

Following The AVIC Development Mod, we would like to introduce a new Debug menu that was discovered by examining the Av.apk. This mode seems to be one of the developer menus that Pioneer themselves used to develop the software.  It seems to be compatible with all decks that The AVIC Development Mod is compatible with.

 

This menu includes but is not limited to:

• USB OTG Switching (We have yet to see this truly working)
• Boot Mode Changes (No need for bsp flashing)
• Stock Android Developer Settings Menu
• Sensor Debugging
• Logcat Log Levels
• Component Logging
• Creating the WARP Snapshot
• Creating the UserData Snapshot
• Saving off the device database
• Saving off logs
• Displaying CPU usage imanformation

 

How To:

 

1. ​Select Off in the Source Settings
2. There are 3 invisible buttons on this screen. See the image below for a picture of the screen, with the Layout Guides Enabled.   
3. 
4. There are 3 boxes in the center screen those are the invisible buttons, for reference we will designate them buttons 1-3 left to right.
5. Enter the following sequence on the buttons: Button 3, Button 1, Button 3,  Button 1, LONG press Button 2.   The first 4 presses should be normal button presses, not long presses.
6. When done correctly you will receive a password prompt. Enter DEVELOPDBG ON There are 2 other passwords but they have just a subset of the options that this one has.
7. Click Ok.
8. You will be taken back to the Off screen. Press and hold Button 2.
9. You should now be in the development menu.

FAQs

 

What is this mode?

A: It seems to be a developer mode that Pioneer uses at the factory.

 

Why use this over Testmode or the BSP?

A: This mode is safer to use as it is built into the device instead of having to flash your BSP, where something could go wrong.  This is also easier to access as it does require specific files on your USB Key. However this does have limitations as it does not have all of the modes that Testmode has.

 

 

What is Needed

 

With the discovery of this mode, it is clear that there is a way to get ADB access with OTG and the developer settings found here.  Especially since it seems this is the mode that Pioneer has used to aid in the development of the NEX.

 

Sadly every combination of cables and modes we have tried as not worked as of yet. If you find a combination that gets you ADB or have an idea. Please drop it in the thread.

I try to use on my F88 DAB this passw:  DEVELOPDBG ON , but don't work...the system tell me is wrong password. Have you got fresh one?
