Install OkcarOS on
Google Nexus 7 2013 (LTE, Repartitioned)

debx

Basic requirements

  1. Read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps!
  2. Make sure your computer has adb and fastboot. Setup instructions can be found here.
  3. Enable USB debugging on your device.
  4. Boot your device with the stock OS at least once and check every functionality.
  5. LineageOS is provided as-is with no warranty. While we attempt to verify everything works you are installing this at your own risk!

Unlocking the bootloader

  1. Connect the device to your PC via USB.
  2. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
    adb -d reboot bootloader
    

    You can also boot into fastboot mode via a key combination:

    • With the device powered off, hold Volume Down + Power until the bootloader appears, then release the buttons.
  3. Once the device is in fastboot mode, verify your PC finds it by typing:
    fastboot devices
    

    If you don’t get any output or an error:

    • on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
    • on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable and port!
  4. Now type the following command to unlock the bootloader:

    fastboot oem unlock
    
  5. If the device doesn’t automatically reboot, reboot it. It should now be unlocked.
  6. Since the device resets completely, you will need to re-enable USB debugging to continue.

Installing a custom recovery using fastboot

  1. Download Lineage Recovery. Simply download the latest recovery file, named recovery.img.
  2. Connect your device to your PC via USB if it isn’t already.
  3. If your device isn’t already in fastboot mode, on the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
    adb -d reboot bootloader
    

    You can also boot into fastboot mode via a key combination:

    • With the device powered off, hold Volume Down + Power until the bootloader appears, then release the buttons.
  4. Once the device is in fastboot mode, verify your PC finds it by typing:
    fastboot devices
    

    If you don’t get any output or an error:

    • on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
    • on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable (preferably use a USB Type-A 2.0 one or a USB hub) and port!
  5. Temporarily boot recovery on your device:
    fastboot boot recovery.img
    

EFS/Persist Backup

  1. If you are not in recovery, reboot into recovery:
    • With the device powered off, hold Volume Down + Power until the bootloader appears, then release the buttons. Use the volume buttons to scroll to “RECOVERY” and press Power to select.
  2. Now, use the volume buttons to select “Advanced”, and then “Enable ADB”.
  3. Now open Terminal (Linux/macOS), or PowerShell (Windows), run adb -d shell, and then run the following commands within it:
    • dd if=/dev/block/mmcblk0p2 of=/sdcard/modemst1.img
    • dd if=/dev/block/mmcblk0p3 of=/sdcard/modemst2.img
    • dd if=/dev/block/mmcblk0p4 of=/sdcard/persist.img
    • exit
  4. Now from that same Terminal/PowerShell, run:
    • adb -d pull /sdcard/modemst1.img
    • adb -d pull /sdcard/modemst2.img
    • adb -d pull /sdcard/persist.img

Repartition

  1. Download the flashable repartition script from here.
  2. On your device’s screen, choose “Apply Update”, then “From ADB”.
  3. From your Terminal/PowerShell, run adb sideload /path/to/flo-deb_clamor_repartition.zip, filling /path/to/ in with the path you downloaded the repartition zip to.
  4. Now run adb shell from your Terminal/PowerShell, and run the following commands within it:
    • modify
  5. The device will complete the repartition process, please leave it sit for 10 minutes, and when you return it will have something resembling the following on screen::
    2048+0 records in
    2048+0 records out
    1048576 bytes (1.0 M) copied, 0.106720 s, 9.3 M/s
    32768+0 records in
    32768+0 records out
    16777216 bytes (16 M) copied, 0.546387 s, 29 M/s
    
  6. So long as some variation of the previous messages are shown, proceed to hold the volume down and power keys until the device reboots to the bootloader, and then format your data partition:
    fastboot -w
    
  7. Flash recovery onto your device:
    fastboot flash recovery recovery.img
    
  8. Now reboot into recovery to verify the installation:
    • With the device powered off, hold Volume Down + Power until the bootloader appears, then release the buttons. Use the volume buttons to scroll to “RECOVERY” and press Power to select.
  9. Click,”Factory Reset”, then “Format system partition”, then when prompted, select “Yes”.
  10. Click,”Factory Reset”, then “Format cache partition”, then when prompted, select “Yes”.

Installing OkcarOS from recovery

  1. Download the OkcarOS installation package that you would like to install or build the package yourself.
    • (Optionally): If you want to install Google Apps add-on package (use the arm architecture), you can download it from here.
  2. If you are not in recovery, reboot into recovery:
    • With the device powered off, hold Volume Down + Power until the bootloader appears, then release the buttons. Use the volume buttons to scroll to “RECOVERY” and press Power to select.
  3. Now tap Factory Reset, then Format data / factory reset and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage, as well as format your cache partition (if you have one).
  4. Return to the main menu.
  5. Sideload the OkcarOS .zip package but do not reboot before you read/followed the rest of the instructions!
    • On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
    • On the host machine, sideload the package using: adb -d sideload filename.zip.

Installing Add-Ons

  1. Click Apply Update, then Apply from ADB, then adb -d sideload filename.zip for all desired packages in sequence.

All set!

Once you have installed everything successfully, you can now reboot your device into the OS for the first time!

  • Click the back arrow in the top left of the screen, then “Reboot system now”.
