I am trying to install grapheneos on a Pixel 7 for my brother. I am using the WebUSB installer in Vanadium.
Vanadium on my P7Pro is unable to detect the Pixel 7. But Vanadium on my older Pixel 5 detects it no problem. Both devices are up to date and I am using the same cable.
The Android system on P7Pro shows 'charging via USB' in the status area while on the P5 the Android system shows nothing.
Why is this happening?
