DIY: universal EDL cable for Qualcomm-based KaiOS devices (no soldering)

[Luxferre]

Hi folks,

Since we have a lot of Qualcomm-based devices, some of them can be quirky to guess how to enter EDL mode, or how to do it correctly. For instance, with Alcatel you have to first hold both volume keys, then only one of them, for CAT B35 you have to hold * and #, for 8110 you have to hold Up and Down, and during this you must insert the cable. Sometimes you feel being out of spare hands. :)

So, a very simple cable mod (a poor man's jig) comes in handy which requires no soldering at all.

1. Get a spare microUSB cable and strip the insulation somewhere in the middle.

2. Detect the D+ and GND wires (usually green and black) and strip the insulation on them.

Done! That simple. :)

Now, how to use it:

1. Turn off the phone and connect the microUSB end of the cable to it.

2. Press the stripped D+ and GND wires together.

3. Connect the USB end to the PC and hold the stripped wires for about 5 seconds.

4. Disconnect the wires from each other. The PC should detect the 9008 (edl) mode.

Have fun, Army of hardcore!
