The reason for the usage of Custom ROM’s over Stock ROM’s are:ġ) Security: These ROM’s are developed by big companies and hence there are fewer chances of malware/ virus affecting the phone.Ģ) Warranty: Installing a Custom ROM needs root access and this voids warranty of your smartphone in most cases. They also come pre-installed with certain apps. These are the versions of Android developed by the OEM’s for making their phones look unique. The only catch is that the method won’t work on ZTE phones that launched with Android 8.0 Oreo or newer, and it also won’t work on flagship devices like the Axon 9 Pro, Axon 10 Pro, Axon M, etc.Stock ROM’s are the ones that come pre-installed on phones or tablets. Unlike Xiaomi and some other OEMs, ZTE doesn’t even put a safeguard before the EDL mode against such ‘attacks’, thus you can easily trigger the device to boot to emergency download mode via a simple ADB command. As the Firehose protocol has a provision of reading the contents of individual partitions, one can dump the ‘devinfo’ partition from a bootloader-locked device, change the offset where the unlocking parameters are stored, and write the modified image back to the device to unlock the bootloader. ZTE apparently uses the ‘devinfo’ partition to store crucial bootloader state parameters, including the lock/unlock status. Based on this principle as well as the previous research work done by the Aleph Security team, XDA Senior Member alexenferman has now discovered a generic method to unlock the bootloader of a bunch of ZTE phones without any data loss. Interestingly, EDL is often utilized by tinkerers to get low-level partition access, which can further be exploited to achieve bootloader unlock on some devices.

The latter is strictly intended for OEM servicing and can be used to ‘unbrick’ a device with appropriate software binaries via a protocol named ‘Firehose’. The regular boot sequence of a typical Qualcomm Snapdragon chipset-powered Android device is initiated with the Primary Boot loader (PBL), although there exists an alternative boot mode called Emergency Down load Mode (EDL).
