Install LineageOS on quill_tab
Back to the overviewDo not continue after something fails!
Basic requirements
- Read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps!
- Make sure your computer has
adb
andfastboot
. Setup instructions can be found here. - Enable USB debugging on your device.
- Make sure that your model is actually listed in the “Supported models” section here (exact match required!)
- Boot your device with the stock OS at least once and check every functionality.
- LineageOS is provided as-is with no warranty. While we attempt to verify everything works you are installing this at your own risk!
Preparing for installation
Tegra devices come with a unique boot mode called “Tegra ReCovery Mode” or RCM, also known as APX. Tegraflash is the official NVIDIA tool for interfacing with RCM mode on recent Tegra devices. Tegraflash is only available for Linux. It will also not run properly in a VM.
Installing a custom recovery using Tegraflash
-
Download a flash package.
- For TX2 Devkit, It will be named
p2771_flash_package.tar.xz
. For TX2 NX Devkit, It will be namedp3636-p3509_flash_package.tar.xz
.
Note: These flash packages were built by LineageOS Developer Aaron Kling (webgeek1234) from officially supported LineageOS repositories, using Tegraflash and device configurations from NVIDIA Linux4Tegra releases and a few custom scripts. - For TX2 Devkit, It will be named
- Install
xz
andpython3
. To do so, runsudo apt -y install xz-utils python3
(Debian based hosts) ordnf -y install xz-utils python3
(Redhat based hosts). -
Run the following command in the folder which you downloaded the flash package to:
- For TX2 Devkit,
tar -xvf p2771_flash_package.tar.xz
. For TX2 NX Devkit,tar -xvf p3636-p3509_flash_package.tar.xz
.
- For TX2 Devkit,
- Power off the device, and boot it into download mode:
- For TX2 Devkit - With the device off, press the FRC REC button, then tap POWER. Release FRC REC once apx enumerates. For TX2 NX - With the device unplugged, jump the FRC REC pin, then plug in. Remove the jumper once apx enumerates.
- Now, from the same terminal as before, run:
sudo ./flash.sh
Note: Please note this will require your user’s sudo password, as the script requires direct hardware access, which requires root privledges. - The script will flash the boot stack and boot directly to recovery.
Installing LineageOS from recovery
- Build a LineageOS installation package.
- (Optionally): If you want to install an application package add-on such as Google Apps (use the
arm64
architecture), please read and follow the instructions on Google Apps page
- (Optionally): If you want to install an application package add-on such as Google Apps (use the
- If you are not in recovery, reboot into recovery:
- The bootloader does not allow using hardware buttons to boot to recovery. After apx flash, the device will boot directly to recovery. After installing Lineage, normal methods can be used to reboot to recovery.
- 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).
- Return to the main menu.
- Sideload the LineageOS
.zip
package:- On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
- On the host machine, sideload the package using:
adb sideload filename.zip
.Tip: Normally, adb will reportTotal xfer: 1.00x
, but in some cases, even if the process succeeds the output will stop at 47% and reportadb: failed to read command: Success
. In some cases it will reportadb: failed to read command: No error
oradb: failed to read command: Undefined error: 0
which is also fine.
-
(Optionally): If you want to install any add-ons, click
Advanced
, thenReboot to Recovery
, then when your device reboots, clickApply Update
, thenApply from ADB
, thenadb sideload filename.zip
those packages in sequence.Note: Add-ons aren’t signed with LineageOS’s official key, and therefore when they are sideloaded, Lineage Recovery will present a screen that saysSignature verification failed
, this is expected, please clickContinue
.Note: If you want the Google Apps add-on on your device, you must follow this step before booting into LineageOS for the first time! - Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.
