Hi guys,
I have installed GrapheneOS on a Pixel 6A device successful, but now I need to patch the boot loader (Magisk) for research purposes, but this fails, as the device does not show as a fastboot device.
Steps followed:
- Installed latest adb/fastboot via brew (I am on MacOS 13.5). fastboot version: 34.0.4-10411341
- Installed GrapheneOS using web installer
- Updated GrapheneOS via OTA (bluejay-factory-2023080800).
- Ensured USB Debugging is enabled and boot loader unlocked.
- Run
adb devices
-> device is shown with its serial number and commands are working. - Run
adb reboot bootloader
- device goes into "fastboot" mode, as visible on its screen.
- Run
fastboot devices
gives no result - Run
adb devices
gives no result (empty list). lsusb
in this state shows:
Bus 000 Device 001: ID 18d1:4ee0 Google Inc. Pixel 6a Serial: 33311JEGR09924 Bus 000 Device 000: ID 18d1:4ee0 Google Inc. USB 3.1 Bus
I have also tried manually putting device into fastboot mode using the combination of volume up key & the power button, but the device is still not shown.
Also tried the exact same thing on exactly the same Mac + USB Cable with another Pixel 6a device running stock android and there the device is detected even in fastboot mode. Which suggests that it may be because of GrapheneOS itself.
Please anyone any help is appreciated, kind of stuck in a desperate situation as I need a rooted device for my thesis. Thanks in advance.
