Introduction With the Introduction of the AVIC Development Mod (http://avic411.com/index.php?/topic/81468-the-avic-development-mod/). We would like to encourage you to backup your AVIC Internal SD Card and its NOR Flash. Lets also keep all backup links and discussion here NEVER ENTER COPY DEVICE MODE, YOU WILL BRICK YOUR DEVICE! The following will show you how to do that: 1. Backup your current BSP and Nor Flash. A. Download the attached NORFlashBackup.zip B. Extract the contents to a FAT32 or NTFS USB Stick. C. Insert the USB Stick to USB Port 1 on the device. D. Follow the "Copy Script Mode" steps. On http://avic411.com/index.php?/topic/81468-the-avic-development-mod/ E. Grab the USB Stick and save off the mtd0_backup1 -3 files. (Should your device ever brick, these can be used with a JTAG to fully restore your NOR flash or to find out your default BSP Settings) 2. Backup your Internal SD Card (Skip to 3 if you have an unlocked image you want to use) A. Download the attached InternalSDCardBackup.zip B. Extract the contents to a NTFS (IMPORTANT as FAT32 can not store files bigger than 4GB) USB Stick (You can also use a SD Card on the external SD Card if you edit the script). ALSO: The USB Stick must be bigger then your internal SD Card, to store the image. Known sizes are: 4000 - 4GB, 5000-7000 - 8GB, 8000 - 16GB. THIS IS A CURRENT GUESS. To be safe, use a USB Stick larger than 16GB. C. Insert the USB Stick to USB Port 1 on the device. D. Follow the "Copy Script Mode" steps. http://avic411.com/index.php?/topic/81468-the-avic-development-mod/ (NOTE: This can take a long time depeneding on your device's intenral SD Card size. It can also timeout, Pressing the Vol - while this is running every 15 min seems to keep it from turning off.) It took us 45 min to copy the 4GB card on the 4000 NEX copying to USB1. It took ~40 minutes for a 16GB internal card and 64GB external SD Card (copyscript copying data to external SD, instead of the USB) with 1MB block size (bs=1048576 parameter). For someone else it took ~80 minutes for a 16GB SD Card copying to USB. E. Grab the USB Stick and save off the AVIC.img file to your computer. This is the full Unlocked SD Card Image of your device.

Introduction WhatIsBypass, AdamOutler and myself present The AVIC Development Mod We have eliminated the barriers to development on all AVIC units including Android Auto. You can now create your own ROM on an SDCard and boot directly into it. We've broken all the security and obfuscations, and we've delivered it to you in a nice, easy-to-use web user interface. This has essentially turned the Pioneer line of units into Nexus devices, that boot off SD Cards. We now have the ability to change the NEX BSP Settings which allow us to unlock the SD Card and change the boot settings that are in the Pioneer NEX. We are asking all ROM developers with a NEX step and help us create our own ROM to run on all versions on the NEX System. With the help of all you we can begin to add USB Wifi Drivers, a custom app launcher, the play store, interface skins, more radio presets, radio station data augmented by the internet, Android Auto, iDatalink Gauges, and much more only limited by what we can develop. NEVER ENTER COPY DEVICE MODE, YOU WILL BRICK YOUR DEVICE! It is fixable though but a pain as described by WhatIsWhat Overview Here's a quick overview of what we will do in this post. Overview Steps: 1. Backup your current BSP and Nor Flash 2. Backup your current internal SD Card, or obtain a backup SD Card Image. 3. Navigate to https://jenkins.adamoutler.com/job/Customize%20BSP/build?delay=0sec and select the options you want 4. Remember your build number and download your package. 5. Extract to USB stick 6. Put it into USB Port 1 7. Run Script. 8. If you removed the SD Card password you need to insert a new internal SD Card with a backup image. 9. Done! How To Let's talk about the details, now. Run Copy Script Mode: 1. Insert the USB Stick to USB Port 1 on the device. 2. Start the deck, it will then reboot into Technical TestMode. You must use the keys to navigate the menus. BE VERY CAREFUL AS SOME OPTIONS CAN BRICK YOUR UNIT. 3. Use the Vol - button to navigate to "Write Programs Forcibly" 4. Press the Home Button to select this menu 5. Use the Vol - button to navigate to "Copy Script" 6. Press the Home Button to select this menu 7. Take note of the Values on the right hand side of the screen, THESE WILL BE ERASED. (It is currently unknown if these will be needed in the future). If you really want to keep these values though, you can write them down and place them in the corresponding SDCardCWWVersion.txt before you continue. 8. Press the Home Button to run the script. 9. After it says 100% press the Home Button to reset the unit and remove the USB stick. Full Steps to get to a development state: 1. Backup your current BSP and Nor Flash. See http://avic411.com/index.php?/topic/81469-avic-development-mod-device-backup/ for this. 2. Backup your Internal SD Card (Skip to 3 if you have an unlocked image you want to use) See http://avic411.com/index.php?/topic/81469-avic-development-mod-device-backup/ for this. 3.Install a Customized BSP A. Navigate to https://jenkins.casual-dev.com/job/Customize%20BSP/build?delay=0sec B. Select the options that you want to enable. The currently known defaults are already selected. For development select debugSwitch: Debug On Console On, subBootMode: Disable Warp, choicePassword: Remove the Password C. Click Build and note the build number that was started on the left. D. Navigate to https://jenkins.casual-dev.com/job/Customize%20BSP/NSERT_BUILD_NUMBER_HERE/artifact/ where INSERT_BUILD_NUMBER_HERE is your build number. E. Click the (all files in zip) F. Extract the contents of the download to a USB Stick. (FAT32 or NTFS) G. Follow the "Copy Script Mode" steps. H. The unit when it reboots should error out because you removed the SD Card Password lock. 4. Insert an Unlocked Internal SD Card Image A. dd the AVIC.img you backed up to an SD Card of the appropriate size. B. Insert the new SD Card into the Internal SD Card slot. C. Start up the unit. NOTE: It will take a bit for the device to boot since you have disabled WARP above. 5. Congrats!!!! You can now remove the internal SD Card at will and modify the items in the partition and put it back into the Deck. Good luck on your Custom Rom Development and be sure to share your creations!! What we are now asking of the ROM Community: 1. Help us by developing custom roms using the steps above and sharing your creations. 2. Once we have a custom rom we want to share easily, we will get to the steps where we start Creating a new WARP snapshot, and recompiling them back into PRG Update Files. 3. Find a way to enable ADB, One option would be to add a Network Bluetooth Profile, Another option is figuring out USB OTG properly. 4. Lets create an app launcher. 5. Figure out how to modify the maps. 6. Figure out Android Auto/Bluetooth Audio on older models with the new software.
