Backup your current BSP and Nor Flash.[edit | edit source]

  • Download the attached NORFlashBackup.zip
  • Extract the contents to a FAT32 or NTFS USB Stick.
  • Insert the USB Stick to USB Port 1 on the device.
  • Follow the "Copy Script Mode" steps. On http://avic411.com/index.php?/topic/81468-the-avic-development-mod/
  • 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)


Backup your Internal SD Card (Skip to 3 if you have an unlocked image you want to use)[edit | edit source]

  • Download the attached InternalSDCardBackup.zip
  • 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.

(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.

  • 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.
