Install OkcarOS on
Samsung Galaxy Note10
d1
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
. 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.
警告: 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!
If the vendor provided multiple updates for that version, e.g. security updates, make sure you are on the latest!
If your current installation is newer or older than Android 12, please upgrade or downgrade to the required version before proceeding (guides can be found on the internet!).
Checking the correct firmware
Installation on your device requires a specific firmware version to be installed before you continue.
- Firmware refers to a device-specific set of images that are included in, and updated by the stock OS
- OkcarOS builds for this device require a specific version of the stock OS to be installed prior to following the installation guide
- Please ensure that you are checking the Android version, and not the vendor OS version
- Being on another custom ROM, including unofficial builds of the same version of OkcarOS, does not ensure that this requirement has been fulfilled
- Please re-read this section as many times as necessary to fully understand the requirements
Failing to install the correct firmware version prior to installation may result in failure to install OkcarOS, unexpected crashes post-installation, or permanent damage to your device!
Pre-Install Instructions
- Connect the device to a Wi-Fi network.
- Enable Developer Options by pressing the “Build Number” option in the “Settings” app within the “About” menu
- From within the Developer options menu, enable OEM unlock.
- Power off the device, and boot it into download mode:
- With the device powered off, hold Volume Down + Volume Up and connect USB cable to PC.
- Now, click the button that the onscreen instructions correlate to “Continue” and/or “Unlock Bootloader”.
- Your device will reboot, you may now unplug the USB cable from your device.
- The device will demand you format userdata, please follow the onscreen instructions to do so.
- Run through Android Setup skipping everything you can, then connect the device to a Wi-Fi network.
- Re-enable Development settings by clicking the “Build Number” option 10 times, in the “Settings” app within the “About” menu, and verify that “OEM Unlock” is still enabled in the “Developer options” menu.
Preparing for installation
Samsung devices come with a unique boot mode called “Download mode”, which is very similar to “Fastboot mode” on some devices with unlocked bootloaders. Heimdall is a cross-platform, open-source tool for interfacing with Download mode on Samsung devices. The preferred method of installing a custom recovery is through Download Mode – rooting the stock firmware is neither necessary nor required.
- Enable Developer Options by pressing the “Build Number” option in the “Settings” app within the “About” menu
- From within the Developer options menu, enable OEM unlock.
- Download and install the appropriate version of the Heimdall suite for your machine’s OS
- Windows: Extract the Heimdall suite zip and take note of the new directory containing
heimdall.exe
. You can verify Heimdall is functioning by opening a Command Prompt or PowerShell in that directory and runningheimdall version
.- If you receive an error, install the Microsoft Visual C++ 2015-2019 Redistributable Package (x86) on your computer.
- Linux: Extract the Heimdall suite zip and take note of the new directory containing
heimdall
. Now copyheimdall
into a directory in $PATH, a common one on most distros will be /usr/local/bin. For examplecp heimdall /usr/local/bin
. You can verify Heimdall is functioning by opening a Terminal and runningheimdall version
. - macOS: Mount the Heimdall suite DMG. Now drag
heimdall
down into the/usr/local/bin
symlink provided in the DMG. You can verify Heimdall is functioning by opening a Terminal and runningheimdall version
.
注意: These Heimdall suite distributions were built by OkcarOS Developers Nolen Johnson (npjohnson) and Jan Altensen (Stricted), as the Heimdall suite executables distributed on the official Heimdall website were outdated and the repo mostly abandoned. Modifications were made to make it build and function on modern OSes. - Windows: Extract the Heimdall suite zip and take note of the new directory containing
- Power off the device, and boot it into download mode:
- With the device powered off, hold Volume Down + Volume Up and connect USB cable to PC.
- Now, click the button that the on screen instructions correlate to “Continue”, and insert the USB cable into the device.
- For Windows users only: install the necessary drivers. A more complete set of instructions can be found in the Zadig user guide.
- If nothing relevant appears, try uninstalling any Samsung related Windows software, like Samsung Windows drivers and/or Samsung Kies.
- Run
zadig.exe
found in your extracted Heimdall directory.注意: For the interested, source and documentation for zadig.exe can be found here. - Choose Options » List all devices from the menu.
- Select Samsung USB Composite Device or MSM8x60 or Gadget Serial or Device Name from the drop down menu.
- Click Replace Driver, then selecting Install Driver from the drop down list built into the button.
- If you are prompted with a warning that the installer is unable to verify the publisher of the driver, select Install this driver anyway. You may receive two more prompts about security. Select the options that accept the warnings and allow you to carry on.
- On your machine, open a Command Prompt or PowerShell (Windows) window, or Terminal (Linux or macOS) window, and type:
heimdall print-pit
- If the device reboots that indicates that Heimdall is installed and working properly. If it does not, please refollow these instructions to verify steps weren’t missed, try a different USB cable, and a different USB port.
Installing a custom recovery using heimdall
- 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! - Power off the device, and boot it into download mode:
- With the device powered off, hold Volume Down + Volume Up and connect USB cable to PC.
- Now, click the button that the on screen instructions correlate to “Continue”, and insert the USB cable into the device.
- On your machine, open a Command Prompt or PowerShell (Windows) window, or Terminal (Linux or macOS) window, and type:
heimdall flash --RECOVERY recovery.img --no-reboot
Tip: The file may not be named identically to what stands in this command, so adjust accordingly. If the file is wrapped in a zip or tar file, extract the file first, because Heimdall is not going to do it for you. - A transfer bar will appear on the device showing the recovery image being flashed.
注意: The device will continue to display
Downloading... Do not turn off target!!
even after the process is complete. - Unplug the USB cable from your device.
- Manually reboot into recovery, this may require pulling the device’s battery out and putting it back in, or if you have a non-removable battery, press the Volume Down + Power buttons for 8~10 seconds until the screen turns black & release the buttons immediately when it does, then boot to recovery:
- Reboot and immediately hold Volume Up + Power while the device is connected to a PC via USB cable.
注意: Be sure to reboot into recovery immediately after installing the custom recovery. If you don’t the stock ROM will overwrite the custom recovery with the stock recovery, and you’ll need to flash it again.注意: 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:
- Reboot and immediately hold Volume Up + Power while the device is connected to a PC via USB cable.
- 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.
