FlashFire is the most advanced on-device firmware flasher available for rooted Android devices. It can flash full firmware packages from various manufacturers, as well as apply over-the-air (OTA) and ZIP updates - all while maintaining root, and without using a custom recovery. It also offers full device backup and restore functionalities in several formats. Relevant files can be stored on internal storage, SD cards, USB connected storage, or can even be streamed directly to and from your computer using USB or Wi-Fi.

FlashFire is the spiritual successor to the Mobile ODIN app, which was a similar solution (using completely different methods under the hood) exclusively for Samsung devices on older Android versions.

FlashFire is an extremely powerful application, it should be used with caution. Data loss, soft-bricks, and even hard-bricks are possible if used incorrectly. Unless you are an expert user, consult FlashFire's website and this thread before doing anything potentially destructive.

If the FlashFire user interface crashes, please attach the logs of the crash to your post. The SysLog app can help.

If you are experiencing an issue while FlashFire is flashing, please post FlashFire's log file to pastebin, and include the link in your post. The log file can be found at /sdcard/FlashFire/lastlog on your device.

FlashFire's website/manual can be found at http://flashfire.chainfire.eu/.

Note: currently all functionality is unlocked without purchasing Pro. This may change in the future!

MOP user, this sounds great! Interesting thing to note, however, is that MOP still works fine on my note 3 N900T running lollipop. :)

Either way, looking forward to the update! Thanks a ton for all you've done for us!

I bought the PRO version via app. Thank you for your work!

I have Samsung Galaxy S5 DualSIM (G900FD) with rooted 4.4.2. When I go to the directory where is firmware file to update my phone (for ex. in one file G900FDXXU1BOC1_G900FDOXE1BOC1_SER.zip) application always turns off with error message.

Any ideas? Forgive me if is not a topic to asking questions like this one.

Perhaps you have to put a .tar , not a .zip

Successfully installed in SM-G900K KT(Korea Telecom) Korean version S5. Thanks Chainfire, greatwork. Even though I had MOP, I went ahead and purchased the pro version of Flashfire. At workright now, but I look forward to testing and checking it out a little bit later. I will also post results and comment. Thanks again.

**Update** It seems all 4 back up methods make it to the 2nd black screen and stop. First black screen -good. files load - good. Second black screen - screen stays black and blue LED comes on, it almost appears to be 'breathing' fades from medium light to dim light, back and forth. Almost like it is 'thinking'. Partitions(info) seems to be working well. Also scanning folders for a file works well in the Flash ZIP and OTA and also Flash firmware package. Let me know how I can help.
