I'm curious to know if there is a good way to do this on a phone with a broken screen. I have accumulated a few phones with 3+ gig of RAM, a decent number of moderately good ARM cores, but with broken screens. Essentially this means all control with the device has to be on the few buttons, and the USB, and all feedback must be through USB (or maybe audio) How transplantable are screens between phones? Assuming no geometric fit is required, are the connectors/interfaces standardised inside enough to bodge a temporary screen long enough to set-up a remote interface.

How old are they? I was surprised to discover that plugging my 2019-era Samsung device into a thunderbolt 3 dock (to charge, I assumed) lit up the monitors as external displays and enabled control with a keyboard and mouse.

Switching to pmOS may be bit hard but can run Docker containers on Android. (Although steps differ.) About Android, if a device got adb enabled, can use scrcpy to display and control the device from PC. Considering this, the problem is reduced in enabling adb. If the device supports HDMI-out, can use a USB-C hub to have output and PC connection. If the device supports OTG, can use scrcpy's OTG mode (or attach a mouse via an adapter) and enable adb by doing the required steps manually. If no HDMI out, have to do them blindly. But should be possible using an automation/input tool (like xdotool) to script them. (This procedure can also be used to OEM unlock if want to install pmOS.) If the device is blessed with unlocked bootloader, can `fastboot boot` a TWRP IMG (almost every device has a TWRP port) that has adb enabled by default. From PC can then set persist enable to true and push authorization keys. If cannot run a custom recovery but the device allows 3rd-party OTA updates in stock recovery, can flash an UPDATE.ZIP that does the same. Flashing pmOS is also done via fastboot. But probably need to install a custom pmOS IMG to account for the broken screen. Like pre-enabling ssh, similar to how you will do installing Linux to a remote server.
