Thanks to SDX !!
Unlocked bootloader and root access!
flash_image (bmlwrite) is an extremely useful utility for flashing custom kernels, boot logos 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).
This android application, FlashImageGUI, is basically a GUI interface for the linux binary, flash_image provided by google in AOSP for loading custom kernels and recovery images onto the phone. No recovery or adb needed! Flash a custom kernel, boot logo (some devices) and custom recovery all from android w/o rebooting into recovery mode!
The application displays current kernel version information!
Current Device Support:
Full Kernel (Anykernel and boot.img) Flashing and Recovery (zip file or image) flashing: Sprint Galaxy S4, International HTC One, T-Mobile HTC One, Sprint HTC One, HTC EVO 4G LTE, HTC One S, HTC EVO 3D CDMA and GSM, HTC One XL, HTC Droid DNA, HTC Amaze, HTC Vivid/Holiday, HTC EVO 4G, HTC EVO Shift, Google Nexus 4, Google Nexus 10, Google Nexus 7, Samsung Google Galaxy Nexus, Nexus S/Nexus S 4G & LG Optimus
Full Kernel, Logo and Recovery flashing: Samsung Moment, Transform, Intercept and Acclaim - the s3c6410 series of devices
Full Kernel (zImage) Flashing: Samsung Epic
Check application version for updates
The current phone support limitation is due to hardware manufacturer differences and their software implementations. This process can be very dangerous and I'm being very caution by thoroughly testing before releasing. I've started with the phones I am most familiar and hope to cover all those who request it!
I have a personal list of features I am going to be adding over the coming days and weeks in addition to support for other phones. Please feel free to leave feedback here and requests for phone support. If you have any information on flash_image or bmlwrite for your phone, that'll help get me started researching on your phone support request. Thanks!
Install process is the same as any other .apk. Download to computer and adb push or mount sdcard on computer and copy over. Use any file manager, adb, connectbot/terminal emulator to install.
My preferred method, maybe a bit technical: adb install c:\downloads\FlashImageGUI.apk
Market (99 cents!): Flash Image GUI
Release versions (free from my personal hosting): Flash Image GUI
Any questions, comments, concerns, or issues, please post in this thread or send me an email! Thanks for all the help and support!
Please post any helpful feedback. I'm always looking to improve the application!
Users Guide for flashing ONLY a Kernel (zip file):
1) Ensure the bootloader is unlocked and root access is properly setup
2) Make sure the selected Kernel is compatible with the currently loaded ROM. If not, this will result in a lot of frustration!!! See troubleshooting steps below.
3) Download kernel zip file to /sdcard.
4) Open Flash Image GUI, browse and select kernel zip file, downloaded/loaded to sdcard in previous step.
5) Flash Image GUI will validate the kernel zip file is contains the minimum required files
6) Select the Flash Image button and Flash Image GUI will load the kernel and the kernel modules from the source kernel zip file.
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 itself or the ramdisk packaged in the kernel is NOT compatible with your device!!!
Solution for #1: Have to boot into fastboot (or directly into the custom recovery) 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.
