Installation
0. Unlock your bootloader, by going into Developer Options in Android, and toggling OEM Unlocking on, then booting to Fastboot and running
$ fastboot flashing unlock
$ # now agree on your device with the Volume Up key
1. Select the device in pmbootstrap and run install as normal.
2. Install Das U-Boot. It's available here. To flash, use:
$ fastboot flash lk <path-to-u-boot.img> reboot
3. Your device should reboot and display the U-Boot logo, as well as a note that it is in Fastboot mode.
4. Now you can flash the device with pmbootstrap, like normal.
$ pmbootstrap flasher flash_kernel
$ pmbootstrap flasher flash_rootfs
$ fastboot reboot
5. Enjoy postmarketOS!
Device quirks
- Fastboot appears to not work properly if the device is plugged into the host when entering fastboot mode. In this case, any fastboot command will halt seemingly forever and without action. A command can still be executed by unplugging the device, issuing the command, and then reconnecting the cable; or simply by rebooting to fastboot again without a cable connected. (Has to be verified the bug still exists under u-boot)
- This device uses a new flashing protocol, unsupported by mtkclient. It can read partitions, but flashing fails (and yes, I am alive is real and comes from device.):
[SEC_POLICY] lock_state = 0x3
Security deny for [lk_a].
I am alive.
UART
UART can be accessed on the motherboard, close to the camera (requires disassembly). The pins operate at 1,7V.
