WARNING: The provided instructions are for OkcarOS 17.1. 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.
- 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
crackling-13-ge86e772
, 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
NOTE: The steps below only need to be run once per device.
WARNING: Unlocking the bootloader will erase all data on your device!
Before proceeding, ensure the data you would like to retain is backed up to your PC and/or your Google account, or equivalent. Please note that OEM backup solutions like Samsung and Motorola backup may not be accessible from OkcarOS once installed.
-
Enable OEM unlock in the Developer options under device Settings, if present.
- Connect the device to your PC via USB.
- 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 and connect the USB cable.
- 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 and port!
-
Now type the following command to unlock the bootloader:
fastboot oem unlock
NOTE: At this point the device may display on-screen prompts which will require interaction to continue the process of unlocking the bootloader. Please take whatever actions the device asks you to to proceed. - If the device doesn’t automatically reboot, reboot it. It should now be unlocked.
- Since the device resets completely, you will need to re-enable USB debugging to continue.
Installing a custom recovery using fastboot
- Build a OkcarOS installation package. The recovery will be built as part of it!
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 and connect the USB cable.
- 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.
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 the correct firmware
- If your bootloader property matches the one stated above, you can skip the following two steps, if it doesn’t you will need install the latest CyanogenOS 13.1 firmware (Android 6.0.1 Marshmallow) before proceeding. To do this, follow the instructions below:
- Download the latest CyanogenOS 13.1 firmware from here.
- 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.
- Sideload the
SW27-WF-CRACKLING-CM-13.1.5-ZNH2KAS7EB-RECOVERY_v2.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 SW27-WF-CRACKLING-CM-13.1.5-ZNH2KAS7EB-RECOVERY_v2.zip
NOTE: The firmware package in question is signed by the OEM, but isn’t signed with OkcarOS’s official key, and therefore when it is sideloaded, Lineage Recovery will present a screen that saysSignature verification failed
, this is expected, please clickContinue
.
Installing OkcarOS from recovery
- Build a OkcarOS installation package.
- (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.
- 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.
