How to enter flash mode

BQ bootloader

  • Recovery: Power on the device with both Power and Volume Up buttons.
  • Fastboot: Power on the device with both Power and Volume Down buttons.

Cyanogen bootloader

  • Recovery: Power on the device with both Power and Volume Down buttons.
  • Stock fastboot: Power on the device with both Power and Volume Up buttons.
  • lk2nd Fastboot: Power on the device. After it vibrates, hold Volume Down.

Installation

Unlock bootloader

To unlock your bootloader, boot into Android, enable Developer Options from the settings and enable "Allow OEM unlock". Then boot into Fastboot and use fastboot oem unlock. You might need to use fastboot oem unlock-go. (Note: All your data will be erased!)

Firmware

It is recommended to flash to latest firmware from BQ before using postmarketOS. You can download it here: 5.2.0_20180228-1305-picmt-user-637-Fastboot-FW.zip.

First flash the early boot firmware:

$ fastboot flash sbl1 sbl1.mbn
$ fastboot flash sbl1bak sbl1.mbn
$ fastboot flash tz tz.mbn
$ fastboot flash tzbak tz.mbn
$ fastboot flash hyp hyp.mbn
$ fastboot flash hypbak hyp.mbn
$ fastboot flash rpm rpm.mbn
$ fastboot flash rpmbak rpm.mbn
$ fastboot flash modem NON-HLOS.bin

As a next step you also need to flash a Linux/Android bootloader (aboot). This depends if you want to run downstream (bq-picmt in postmarketOS) or mainline (bq-paella in postmarketOS).

Downstream

You can use the bootloader from the BQ firmware you downloaded before:

$ fastboot flash aboot emmc_appsboot.mbn
$ fastboot flash splash splash.img

The bootloader has a splash screen with white/black background (likely depending on the color of your device).

Mainline/Downstream

The BQ bootloader is unable to boot lk2nd, therefore you need to flash the bootloader from the Cyanogen firmware. You can download it here: cm-13.1.4-ZNH2KAS5FE-paella-signed-fastboot-a6851b4fbe.zip

$ fastboot flash aboot emmc_appsboot.mbn
$ fastboot flash splash splash.img

The bootloader has a splash screen with black background.

postmarketOS

Downstream

Choose bq-picmt and follow the Installation guide.

Mainline

  1. Install lk2nd following the Building section (just needed the first time).
  2. Choose bq-paella and follow the Installation guide (flash from lk2nd, not the Cyanogen fastboot).

Audio

See Qualcomm_Snapdragon_410_(MSM8916)#Audio.

Modem

See Qualcomm_Snapdragon_410_(MSM8916)#Modem.

Status

Currently work is separated based on firmware installed, if you installed the Cyanogen Edition firmware will be referred as bq-paella, if you installed the BQ Android firmware it will be referred as bq-picmt. So here is a summary for both:

bq-picmt: runs on downstream kernel

Works: USB Network, WiFi, Display, weston, weston-calibrator

Buggy: ts_calibrate: to make screen get touches I incrementally have to touch screen with one finger and then with that finger on screen touch the crosshair, then for the second two fingers and crosshair, for the third three fingers and crosshair...don't know why but it started happening when I replaced my broken screen with a new one, if someone has this device with original screen can check if the same issue is present or not

Modem doesn't work, in dmesg I get DATA5_CNTL error relative to no such device

bq-paella: runs on mainline kernel

Works: USB Network, WiFi, Bluetooth, Display, Touchscreen, Volume buttons, Accelerometer, Gyroscope, Magnetometer, Touchkeys backlight, Audio (Headphones, Earpiece, Speaker, MIC), Voice calls, SMS
