What is FlashFire?




FlashFire is an app developed by Chainfire, a well-known developer in the Android community. Chainfire is also the creator of other popular apps such as SuperSU, Mobile ODIN, and CF-Auto-Root. FlashFire is the successor to Mobile ODIN, which was a similar solution for Samsung devices on older Android versions.


FlashFire is an app that allows you to flash firmware packages directly from your device, without using a PC or a custom recovery. It supports various formats of firmware packages, such as TAR, ZIP, OTA, IMG, and KDZ. It also supports various devices from different manufacturers, such as Samsung, LG, HTC, Sony, Motorola, OnePlus, and more.


FlashFire has many features that make it a powerful and convenient tool for flashing firmware. Some of these features are:


  • EverRoot: This feature allows you to root the firmware while you flash it. This means you don't have to worry about losing root access when you update your device.



  • Backup and restore: This feature allows you to backup and restore your device's partitions in several formats. You can store the backup files on internal storage, SD card, USB storage, or even stream them directly to and from your computer using USB or Wi-Fi.



  • Wipe: This feature allows you to wipe your device's partitions before or after flashing. You can choose which partitions to wipe, such as data, cache, dalvik-cache, system, etc.



  • Inject ZIP: This feature allows you to inject additional ZIP files into the firmware package before flashing. You can use this feature to install mods or tweaks that are compatible with the firmware.



  • Mount /system read/write: This feature allows you to mount the /system partition as read/write after flashing. You can use this feature to make changes to the system files or install apps that require system access.



How does FlashFire work?




FlashFire works by using a special mode called Direct Mode. In this mode, FlashFire bypasses the normal boot process and boots directly into a minimal environment where it can perform the flashing operations. This mode allows FlashFire to access the device's partitions without interference from the Android system or the custom recovery.


To enter Direct Mode, FlashFire requires root access and a compatible kernel. The kernel must support SELinux in permissive mode and init.d scripts. Most stock kernels meet these requirements, but some custom kernels may not. If your kernel is not compatible with Direct Mode, FlashFire will warn you before proceeding.


When you launch FlashFire for the first time, it will check your device's compatibility and download an additional package if needed. It will also ask for root permission and show you a disclaimer. You should read the disclaimer carefully and agree to it if you understand the risks involved in using FlashFire.
