Flash NEOS - commaai/openpilot GitHub Wiki

You will need ADB and fastboot to unlock your bootloader and flash the OS.

• Windows: https://dl.google.com/android/repository/platform-tools-latest-windows.zip . Extract to folder where you will use these programs in CMD.
• Linux: sudo apt-get install android-sdk-tools-platform -y or your distro equivalent.

If your Oneplus 3T is running Oxygen OS 9.0.x, you will have to rollback to OOS 5.0.x or earlier to avoid issues. You can do this by:

• Using MSM Tool on windows. You have will need proper device drivers (QDLoader) to recognize phone's Qualcomm download mode. I recommend this because you can't go wrong.
  • Install device driver's with this guide: https://forum.xda-developers.com/oneplus-3t/how-to/unbrick-unbrick-tutorial-oneplus-3t-t3515306
    • DO NOT PERFORM STEP 1b, 2, 7, 8, AND 9. We are using firmware in next bullet to rollback.
    • Recent windows appears to recognize this mode and installs QDLoader driver automatically. You can check by booting phone into this Qualcomm Download mode (further down / someone do hyperlink shortcut) and see if device manager has QDLoader driver. If it's unrecognized, go ahead with instructions.
  • Download this: https://www.androidfilehost.com/?fid=11410963190603910547 (OOS 5.0.8) and extract.
• Flashing package with older firmware via TWRP. Fill this in.

You will need eon-neos repo and python 3, this should do the majority of your work!

• python3
  • Windows: https://www.python.org/ftp/python/3.8.2/python-3.8.2.exe
  • Linux: sudo apt install python3 or distro equivalent.
• eon-neos: https://github.com/commaai/eon-neos/archive/master.zip and extract it.

MSM Tool Method (This will relock bootloader):

1. Hold your power button for 40 seconds.
2. Once it is off, hold volume up for 10 seconds and plug phone in. - You should see it recognize it as 'QDLoader' or 'Qualcomm 9008' and not 'Unknown devices' plus 'QHUSB_BULK'. Otherwise, you installed drivers wrong or havent.
3. Launch MSMTool executable in extracted folder and press start.
4. Once it finishes (goes green), it should restart. Otherwise, disconnect and boot into system.

TWRP Method:

1. Fill me in.

Unlocking allows you to flash custom firmware. Necessary for NEOS. You can lock bootloader after installing NEOS to save your precious bootloader warning seconds.

1. Enter settings app.
2. Press 'About phone'.
3. Tap 'Build Number' like a mad lad till you see results.
4. Go back, click 'Developer Options'.
5. Enable 'OEM unlocking' and 'Advanced Reboots'.
6. Hold power button. Press restart then bootloader.
7. Plug your phone in and use fastboot. - On windows, go to folder you extracted and open CMD. use 'fastboot.exe' - On linux, fastboot is avaliable in terminal.
8. Check if phone is properly connected by typing 'fastboot devices'. It should appear and show connection as 'fastboot'.
9. (Warning: will clear data.) Type 'fastboot oem unlock' and say yes to prompts. Your phone will clear data and reboot.

• Fill me in.

You will use eon-neos repo to download and install NEOS OS. DO NOT DISCONNECT THE DEVICE!

Windows:

1. Open powershell and run python download.py.
2. Put your Eon into fastboot mode by turning off your Eon, then holding volume down + power (comma two, eon gold), or volume up + power (eon).
3. Run flash.ps1 (right click, run with powershell).

Linux/OS X:

1. Open a terminal.
2. Run ./download.py
3. Put your Eon into fastboot mode by turning off your Eon, then holding volume down + power (comma two, eon gold), or volume up + power (eon).
