'''Qualcomm EDL mode''' is a boot mode implemented in the [[boot rom]] of devices using [[Qualcomm SoCs]], which includes features such as reading/writing partitions. It can be used for purposes such as unbricking hard-bricked devices, or flashing partitions on devices that lack [[fastboot]] mode or an equivalent.

Various clients for EDL exist, such as Qualcomm's own QFIL, [https://github.com/linux-msm/qdl qdl], or [https://github.com/bkerler/edl bkerler's 'edl']. Unless otherwise specified, the wiki will provide instructions using bkerler's client.

== Bootloader unlocking ==

Some phones' bootloaders can be unlocked using EDL mode, by editing the <code>devinfo</code> partition.

First of all, <code>devinfo</code> must be dumped with <code>edl r devinfo devinfo.bin</code>.

Afterwards, the resulting <code>devinfo.bin</code> should be opened in a hex editor. The partition should have the magic <code>ANDROID-BOOT!</code> at the beginning, and optionally at other locations. Where it occurs, replace this:
<pre>
41 4E 44 52 4F 49 44 2D 42 4F 4F 54 21 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
</pre>
With this:
<pre>
41 4E 44 52 4F 49 44 2D 42 4F 4F 54 21 00 00 00
01 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00
</pre>

Lastly, save the file, and flash it with <code>edl w devinfo devinfo.bin</code>
