For those who are unfamiliar, Flash Image GUI has been around for quite some time. The tool allows users to flash kernels and recoveries with a nice GUI, and all of this is done without requiring them to first reboot into recovery. While recoveries have gotten remarkably friendly over the last couple of years, some would still prefer to stay in the comfort of their favorite mobile OS for the duration of the flash. Now, this tool has added support for the HTC Droid DNA.
XDA Recognized Developer joeykrim, a longtime developer for the project, released the app for the DNA. Judging from user response, it seems to work as well as ever. Here’s the official app description:
flash_image (bmlwrite) is an extremely useful utility for flashing custom kernels, boot logos (so far ONLY Samsung devices) and recoveries. This binary has made it possible to easily flash all these items and is used almost everywhere behind the scenes (i.e. in custom recoveries, packaged into kernel /sbin, etc).
Supports both CWM and TWRP recovery image flashing!
Users simply need to install the APK file like any other app. From there, you open the app, select which kernel or recovery you want to flash, and the app takes care of the rest. It should be noted that there are potentially major inherent risks. Users shouldn’t flash AOSP kernels over Sense-based ROMs, or vice versa. Moreover, those who accidentally flash a bad zip with this tool and don’t have a custom recovery could be in a sticky situation. That’s why you should go ahead and make sure you have (a very good) one before proceeding.
At minimum, devices will have to be HTCDev unlocked in order for this app to function properly. While the app itself is easy to use, it should also be noted that it’s flashing some pretty important software so there is a chance bad things can happen. Be sure to have a Nandroid backup handy at all times and follow instructions to help minimize the potential risk.
