Check out both the ways to boot into EDL from fastboot. But remember this method has its limitations so there might be chances that it may not work in your case.Īlso in fastboot mode, there are another two ways to boot into EDL. Also booting into EDL mode depends on vendor, device condition etc. It is not guaranteed that the method you pick will definitely work for you. There is more than one way to boot into EDL mode. This is not all there are many more features of EDL Mode.

EDL mode is used to unlock bootloaderunbrick devices, access internal storage, change software, update phoneflash firmware.

How cool is that? Mainly the post is about how to boot into EDL mode on any android phone.Īnd after booting into EDL mode what we can do.

Also if you are looking forward to enter in the development then definitely you need to know all about this.īut if you know then you can fix any problem with the software on your own. These guides come in handy when there is a problem with the phone like bootloop, stuck at logo, not booting up, recovery deleted.

Nokia, LG, Motorola, and Google programmers leaked rather than being released, yet the researchers managed to break the entire chain of trust on the Nokia 6 and gain full device access through similar methods of exploitation.Other tutorials are also available you can go to their link for more info. It is unknown why OEMs release these programmers from Qualcomm. They then flashed a custom kernel which gave root access and launched SELinux in permissive and also extracted the encrypted userdata image from the device.
The researchers also used this to unlock a Xiaomi device simply by flashing a modified image which unlocked the bootloader. Firehose works through the Qualcomm Sahara protocol, which accepts an OEM-signed programmer and is how the above attack would be carried out. If an attacker wished to take this a step further, they could flash a malicious custom kernel which enables root access to the device which the user would never know about. Simply by running the above fastboot commands, an attacker can have full access to the device.
If you remember, OnePlus was previously found to have left two dangerous fastboot commands nearly a year ago, one which unlocked the bootloader and one which disabled secure boot.
EDL Mode can be utilized in a number of ways on a device, mostly for unbricking devices by force flashing them. Old Xiaomi devices can utilize this method, along with the Nokia 5 and Nokia 6. Some system preparations are done, and then code execution is transferred over to the kernel.īoot sequence of a standard Android device visualised. The S oftware B oot l oader SBL is a digitally signed bootloader which is checked for authenticity before being loaded into imem.įollowing this, TrustZone hardware-based security is also loaded. It is important to first understand the boot sequence of a typical Android device before explaining how it can be exploited. It is theorized to work the same way on other devices, and the researchers also managed to unlock and root multiple Xiaomi devices without any data loss.įirstly, the devices which are affected. The attackers utilized the level of access granted to the EDL mode to bypass secure-boot on a Nokia 6defeating the chain of trust and gaining full code execution across every part of the boot sequence including the Android OS itself. Security researchers Roee Hay roeehay and Noam Hadad from Aleph Research have discovered critical device vulnerabilities using this mode, which effectively grants an attacker full device access. Many OEMs including OnePlus and Xiaomi have released tools known as programmers which utilize EDL mode and a protocol known as Firehose to unbrick a device, while other tools from companies such as Nokia have leaked.
