How to enter flash mode
Hold Power + Volume Down while the phone is turned off. This will make the phone boot into fastboot mode
You will need to unlock the bootloader in order to be able to flash anything onto the phone.
Installing TWRP before doing anything else is recommended, as it makes dealing with the phone easier later on, and allows for quick restoration by taking backups of
/boot, then flashing them back in order to restore the device to its original state. Note that this method has only been tested with LineageOS, and running its installation ZIP in TWRP after restoring the backup was necessary to get it to boot, otherwise it would just keep loading forever.
|NOTE: Flashing to the system and boot partitions will wipe the Android core but will leave all apps and user files. If you want to be able to easily restore Android, it is recommended to backup both partitions using the method above.|
|Flashing to the data partition will erase all user data! Make sure all important files are backed up before flashing.|
Official images are available for this device. Those can be directly flashed with fastboot for a quick install.
Choose an image for your device from the download page.
Once downloaded, decompress the images with
$ xz -d <image>-xiaomi-scorpio.img.xz $ xz -d <image>-xiaomi-scorpio-boot.img.xz
Once decompressed, you may flash the main image to either:
/system: ~3.2 GB. Will allow you to keep the main part of your existing Android installation as well as your data.
$ fastboot flash system <image>-xiaomi-scorpio.img
/data: Extends close to the remaining size of your storage. Will wipe your Android installation along with your data.
$ fastboot flash data <image>-xiaomi-scorpio.img
Then you may either flash the boot image:
$ fastboot flash boot <image>-xiaomi-scorpio-boot.img
or boot it directly without flashing:
$ fastboot boot <image>-xiaomi-scorpio-boot.img
Initialization and Building
Follow the Installaton Guide to initialize pmbootstrap and build/install everything necessary.
Once you reach the flashing step:
- Flash the rootfs:
$ pmbootstrap flasher flash_rootfs
|NOTE: If you need more space in the rootfs, you can also flash to the data partition by appending
- Flash the kernel and initramfs to the boot partition:
$ pmbootstrap flasher flash_kernel
You can also avoid flashing them and instead, boot the kernel directly:
$ pmbootstrap flasher boot

Mobile data will require a driver for IPA.
Calls have not been tested, and while it might be technically possible to make and receive calls, it will not be of much use since the earpiece and microphones are not working.
|IR Transmitter||PM8994 LPG2||Y||IR LED works. Usage with an actual IR receiver device not tested, but should work.|
|Audio Codec||WCD9335 (Headphones, earpiece, microphones)

|Battery||PMI8996 SMBCharger/Fuel gauge2
|P||Fuel gauge works. Charging will require drivers for PMIC SMBCharger and SMB1351.
Charger currently defaults to a low current state so it charges slowly. Also without a charger driver, Linux doesn't know when a charger is plugged in and no indication of charging is made.

The display comes up blue after initialization sometimes. Rebooting makes it work usually.This issue has not appeared since MSM DRM was set to be compiled as a module. Should be completely resolved with the addition of an interconnect driver. System locks up when accessing memory intensively. This might be caused by writing to a protected area of memory.Adding this reserved memory region fixed it. System crashes when modem and ADSP get powered up at the same time.Fixed temporarily through pmaports!2283.
- USB VBUS turns off instantly when a USB device is plugged into an already plugged in OTG adapter. For now the OTG adapter must be plugged into the phone with the USB device plugged into it already.
- WiFi range is bad. This is due to lack of board firmware. Supplying board firmware made from the vendor firmware for the downstream QCA_CLD driver makes it lose all APs in a scan as soon as an attempt is made to connect to one of them, which means it is impossible to connect.
