How to enter flash mode

Turn off the device
Press Power + Volume Down to enter fastboot

Installation

CAUTION: Flashing any image with antirollback index lower than 4 (Android 8 or lower, for example) could potentially brick your device due to Anti-rollback protection. See a related XDA Developers post for more information.

Here's how to boot pmOS via fastboot:

Install to a SD card with pmbootstrap install --sdcard=/dev/sdX
Insert the SD card into the device
Connect the device to your PC
Enter the fastboot mode
In order to boot an image with fastboot, an 8-Kb image of zeros should be flashed to the antirbpass partition every time we want to use pmbootstrap flasher boot or fastboot boot. Create an image if you haven't done that already:
```
$ dd if=/dev/zero of=dummy.img bs=8K count=1
```
Flash the freshly created dummy.img to the antirbpass partition:
```
$ fastboot flash antirbpass dummy.img
```
Finally, boot pmOS. Note that it does take a while to load the desktop:
```
$ pmbootstrap flasher boot
```

Alternatively, flashing a zip image through the recovery does not appear to trigger anti-rollback protection.
This has only been tested on one device with the following procedure, proceed at your own risk:

Create a recovery zip with pmbootstrap install --android-recovery-zip
Export the zip with pmbootstrap export, this will create a link to the zip at /tmp/postmarketOS-export/pmos-xiaomi-whyred.zip
Copy the zip to your device and flash with the recovery of your choice, though this has only been tested on OrangeFox Recovery R11.0.

Your recovery may show some warnings during the install process and warn you that no OS is installed after flashing postmarketOS. You can ignore those warnings.

For more info on using recovery zips, see Installation from recovery mode

Accessing UART

Disassemble the device
Unscrew the battery connector holder
Disconnect charging board connector (Note: UART test point is under the charging board connector so you can't use usb while accessing UART or you solder thin wires to it)
