WARNING: The provided instructions are for OkcarOS 20. These will only work if you follow every section and step precisely.
Do not continue after something fails!
Do 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.
WARNING: Make sure that you can send and receive SMS and place and receive calls (also via WiFi and LTE, if available), otherwise it won’t work on OkcarOS either! Additionally, some devices require that VoLTE/VoWiFi be utilized once on stock to provision IMS.
- LineageOS is provided as-is with no warranty. While we attempt to verify everything works you are installing this at your own risk!
Special requirements
WARNING:
Your device must be on bootloader version
US99830b
/ H93031a
/ H930DS30c
, otherwise the instructions found in this page will not work.
The current bootloader version can be checked by running the command getprop ro.bootloader
in a terminal app or an adb -d shell
from a command prompt (on Windows) or terminal (on Linux or macOS) window.
Unlocking the bootloader
Important: An official method of unlocking the bootloader is not available, but there may be some unofficial methods available.
Unofficial methods are not recommended or supported by OkcarOS, so use them at your own risk!
An unlocked bootloader is required to install OkcarOS.
Installing a custom recovery using fastboot
- Download Lineage Recovery. Simply download the latest recovery file, named
recovery.img
.Important: Other recoveries may not work for installation or updates. We strongly recommend to use the one linked above! - Connect your device to your PC via USB if it isn’t already.
- 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 Up + Power.
- 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 runningfastboot
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!
Tip: Some devices have buggy USB support while in bootloader mode, if you seefastboot
hanging with no output when using commands such asfastboot getvar ...
,fastboot boot ...
,fastboot flash ...
you may want to try a different USB port (preferably a USB Type-A 2.0 one) or a USB hub. - Flash recovery onto your device:
fastboot flash recovery recovery.img
- Now reboot into recovery to verify the installation.
Do not reboot into the existing OS, since it will overwrite the recovery you just installed!
-
With the device powered off, hold Volume Down + Power until the LG logo appears, then release Power for a second and hold it again until the recovery comes up.
NOTE: If you can’t power down the device, try long-pressing the key-combination (if any was used in the instructions above) until the device reboots and follow the instructions above
NOTE: If your recovery does not show the OkcarOS logo , you accidentally booted into the wrong recovery. Please start at the top of this section! -
Installing OkcarOS from recovery
- 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
arm64
architecture), you can download it from here.
- (Optionally): If you want to install Google Apps add-on package (use the
- If you are not in recovery, reboot into recovery:
-
With the device powered off, hold Volume Down + Power until the LG logo appears, then release Power for a second and hold it again until the recovery comes up.
NOTE: Accept the factory reset prompt using the hardware buttons. If you have done everything correctly, this will not actually reset your device but instead will boot the custom 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 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
.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.
Installing Add-Ons
NOTE: If you don’t want to install any add-on (such as Google Apps), you can skip this whole section!
NOTE: Add-ons aren’t signed with OkcarOS’s official key, and therefore when they are sideloaded, Lineage Recovery will present a screen that says
Signature verification failed
, this is expected, please click Continue
.WARNING: If you want the Google Apps add-on on your device, you must follow this step before booting into OkcarOS for the first time!
- Click
Apply Update
, thenApply from ADB
, thenadb -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”.
NOTE:
The first boot usually takes no longer than 15 minutes, depending on the device.
If it takes longer, you may have missed a step, otherwise feel free to get assistance.
