Background:

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).

Custom Recovery

Supports both CWM and TWRP!

Future Support:

Will continue to test kernels as they are released to ensure compatibility!

Install Directions:

Install process is the same as any other .apk. Download to computer and adb push or mount sdcard on computer and copy over or download directly to the phone. Use any file manager, adb, connectbot/terminal emulator to install.

My preferred method, maybe a bit technical: ./adb install c:\downloads\FlashImageGUI.apk

Please post any helpful feedback. I'm always looking to improve the application!

Basic Troubleshooting:

Troubleshooting after Rebooting:

First step, when experiencing issues flashing is to RE FLASH the files again. Many times, re flashing again will clear up any issues. If not, see the issues/solutions below.

Issue #1: If the device hangs or reboots while on the splash screen, the kernel (or packaged ramdisk in the kernel) is NOT compatible with your device!!!

Solution for #1: Have to boot into fastboot and load the custom recovery to flash a known good kernel or restore a previously known good nandroid backup. Command: fastboot boot c:\downloads\cwm-recovery.img

Issue #2: If the device hangs or reboots while on the boot animation, the ROM is likely NOT compatible with the kernel!!!

Solution for #2: Have to boot into fastboot and load the custom recovery to flash a known good ROM/kernel combination either from a zip file or restore from a nandroid backup.
