F(x)tec Pro1X is the successor of the F(x)tec Pro1. It features a Snapdragon 662 System on Chip and a QWERTY flip keyboard.

The successor is considered as a downgrade to many people as it featured a weaker SoC compared to previous model which has a Snapdragon 835, multi-state to single-state camera key and removal of the secondary back camera.

How to enter flash mode

Fastboot

Hold down Power and Volume Down while the device is off and release the power button as the phone vibrates. If that doesn't work, try again.

Another way to enter Fastboot mode is to enter Recovery mode (see below) and choose "Reboot to bootloader" option.

Recovery

Hold down Power and Volume Down while the device is off until you're in recovery mode.

If you're using stock F(x)tec recovery, you'll see the Android mascot lying open with "No command." below it. When on this screen, hold down power button and then press and release the Volume Up button to enter the recovery menu.

EDL

Bootloader

Hold down Volume Up and Volume Down and plug in the USB cable while the device is off. The device should now be in QDL mode.

Deep Flash Cable

If your bootloader is corrupted, the deep flash cable can be used to reflash the bootloader or other part of the device.

Installation

The bootloader is the only firmware that postmarketOS doesn't install itself, all other firmware (devicetree, gpu, modem etc) is supplied by postmarketOS. In contrast to custom Android ROMs, it is incredibly unlikely that any bugs or issues you encounter are caused by whatever OS you previously had installed on the device.

Prerequisites

To install prebuilt images, you will need a computer with (the latest) fastboot software.

This can be obtained by installed the android-tools package on Linux or by installing the Android SDK Platform-Tools on Windows, Mac (or Linux).

Enable off-mode charging

It's unsure what this actually do (especially when the battery is completely dead and won't charge), but LineageOS installation guide tells the user to enable it.

This device ships with off-mode charging disabled by default. It is recommended to enable it.

fastboot oem off-mode-charge 1

Build and install the image

You must use "edge" branch as this device is not in community category yet.

Since there is no prebuilt images, you need to build it yourself.

The vendor is "fxtec", the codename is "qx1050".

Follow the pmbootstrap article, until you have done the install action (note that --fde stands for full-disk-encryption - this can also be left out).

pmbootstrap install --fde

Reboot back into flash mode as explained above.

By default the rootfs will be flashed to system, this doesn't leave much free space for your applications / data, if you don't mind factory resetting the device you can instead flash to userdata by specifying the partition like below.

WARNING: Do not reboot via the power button on the device! This can result in not all data being properly written to storage, corrupting the rootfs and resulting strange behaviour like postmarketOS getting stuck during boot!

Always use fastboot reboot after flashing.

fastboot erase dtbo
pmbootstrap flasher flash_rootfs --partition userdata
pmbootstrap flasher flash_kernel
fastboot reboot

Known issues

Power Sensor

A user has reported that trying to read anything from this sensor does not work.

Touchscreen

Due to F(x)tec cheap out on filter components on the touch screen, the touch screen will not work properly on mainline. There is currently no fix for this issue.
