Installation

Note Warning: Flashing lk2nd is required, as it is a hard dependency. Without it the mainline kernel will not select the display panel (resulting in black screen on boot).

How to enter flash mode

While the phone is off, hold the Power + Volume Down buttons together for a few seconds.

How to enter EDL mode

EDL mode (Emergency Download Mode) is a special mode in Qualcomm devices that allows, among other things, flashing firmware even when the phone is completely bricked. This might come useful in case something goes extremely wrong and the device won't even boot to fastboot.

To boot into EDL, you must first disassemble the device in order to expose the motherboard points required. This phone is very easy to disassemble, you can search for videos on YouTube if necessary. Once you have removed the back case and disconnected the battery, find the points shown below on the motherboard:

These are the test points that enable EDL mode. With the battery disconnected, use a metal tweezer or a small wire to short these two points. While keeping them sorted, plug the phone to a computer. The device should show up as "Qualcomm HS-USB QDLoader 9008". You can now use this tool to download firmware to your device.
