  • 4EXT SmartFlash for s-on devices
  • optionally save space by configuring recovery to exclude /cache from backups
  • you can configure recovery to save even more space by excluding dalvik-cache from backups
  • calculates real space needed to complete a backup to save you from troubles
  • detects your local time zone
  • -> correct time is used for backups you start from within recovery
  • allows you to change md5sum check behaviour
  • displays and updates your current battery level in real time
  • scrollable texthistory (drag down the statusbar)
  • built-in interactivity (yes/no questions) for updater-scripts
  • built-in screenshot functionality
  • extensive theming capabilities!
  • nearly ALL YOU SEE is changeable.
  • "worker bar": create your own custom animations, there are (nearly) no limits! Use any shapes/sizes/animations et.c.
  • extra low cpu needed for that: absolutely no negative impact on backup/restore speed.
  • async UI rendering for optimal performance for the "heavy tasks" like backup/restore
  • backups even faster than with usual recoveries.
  • .. explore the new interface to see more
  • includes all features of 4EXT Recovery Classic

About 4EXT SmartFlash

This is a new feature that allows recovery to flash your boot partition just like as if you were s-off.

Credits and thanks to Team Win and Dees_Troy for their commitment to the community, for their amazing idea with the Dumlock and for extra contacting me only to offer that I may use it.
You guys really rock!

SmartFlash is a different approach to Team Win's HTC Dumlock
  • Just use your recovery like you would if your device were s-off
  • No preparations needed, other than telling the recovery that your device is actually s-on
  • This is done when you install recovery and answer the question that you are s-on with "yes"
  • You can also change that setting later on via RecoveryControl -> Recovery settings, or by editing 4ext.prop manually
  • Recovery will autodetect any changes done to "boot" and only attempt to flash your boot partition if it was really changed
  • This even reduces unnecessary writes to "boot" when for example a new rom uses the same kernel as your previous one
  • Before updating your boot partition, recovery will always backup your boot partition to your sdcard just for the case something goes wrong
  • Only the 4 latest boot images are stored, older ones will be removed automatically to prevent taking up too much space.
  • In case you want to enable or disable that feature temporarily, you can use a switch inside the tools menu in recovery

How it works:

  • Recovery will detect any requested changes for your boot partition
  • When you reboot out of recovery, it will prepare updating your boot partition on next rom start
  • This means that your boot partition will be updated when you see the HTC Splash screen, followed by 1 reboot
  • So basically the only visible difference to when you are s-off is one additional reboot, which takes only a few seconds.
  • Recovery is NOT flashed to boot and boot is also only flashed once/update
  • Recovery will only attempt to flash your boot partition if it was really changed

  1. Radio and firmware:
    Usually those are flashed via bootloader flashable zips or fastboot even on devices that are s-off.
    But in case you wondered: this does not enable you to flash new firmwares or radio images via recovery.
  2. SmartFlash needs a working kernel to be able to upgrade your boot partition.
    It cannot work in case your current kernel is incompatible with your device/hboot or has been wiped outside of recovery.
    For example you cannot erase boot via fastboot and then start up recovery to update your kernel.
    However you don't need a working rom to use it.
    The only requirement is that your current kernel is able to start (this happens before you see the boot animation) and that your system partition is mountable.


For App and Rom devs:

Make use of the Recovery Interface Api provided by the (free and paid) 4EXT Recovery Apps to push updates/mods/addons for auto installation.
Very easy to use and to integrate into Apps or even shell scripts.

Please check 3rd post.
Info regarding 4EXT Recovery Touch and its yesno feature, or any interactive installer scripts you might already use, please see 3rd post.


  • This ensures that your downloads are ok by automatically verifying md5sums and that known issues and changelogs are easily accessible
  • When you install or download a recovery via the app it makes sure that your recovery config is correctly set up.
  • It allows to automatically setup your time zone for recovery.
  • You can use it to get notified about updates regarding your recovery version
  • You can configure it to get notified in case any critical bugs have been discovered of the recovery version you currently have installed.
  • It allows me to update known issues/changelogs immediately and to quickly pull a newly released version if there were reports about critical bugs
  • You can also use it to just download a containing the image. The download will be automatically verified for correct md5sums!

By default the app also saves the recovery.img you flash on your sdcard,
so you can use it to flash the recovery via fastboot in case you need to do that one day.

4EXT Recovery Control

For a list of its many features, visit

Some examples :
  • Very easy to use, but also includes an extensive set of features available via "advanced mode"
  • Comfortable configure all settings of recovery
  • Calculate the space needed to create a new full or advanced backup

    So you can make sure the backup will succeed before even rebooting into recovery.
    Advanced Backups: While you are selecting / deselecting partitions, it will display and update the currently needed space to complete that custom backup set.
  • Identifies and adds your romname so you don't need to type so much when chosing a meaningful name for your backup
  • When you restore a backup, the app does the md5sum check instead of the recovery
    This ensures that you know whether the restore process will succeed before even rebooting into recovery
  • Flash as many zip files you want in one go
  • Automatically calculate and display the md5sums of all zip files you are going to flash
  • Check your backups' health to ensure they will restore later when you need them, by verifying their md5sums!
  • Optionally, but highly not recommended:
    If md5sums don't match but you really need that backup badly, you might want to restore it anyway.
    You can you this app to fix the md5sums of a given backup
  • As an example, the following is possible to do in just one session:
    Restore a backup, set to create a backup / advanced backup before the restore,
    format all partitions with a file system of your choice before the restore process starts,
    flash additional zip files afterwards, fix permissions and select to stay inside recovery or to reboot automatically once all actions are complete.
  • Much, much more! See

Big thanks to craacK for a lot of great icons!


Big thanks to DolphiCom for all the graphics, the worker bar and a whole lot of great ideas and to the many great testers who spent all day/night testing, reporting bugs, making suggestions, helping with decisions:

Jotha, craacK, Patrics83, Euphorie, Mike1986, Whiskey103, ptr_hamilton, Lizard, TheUntouchable

Big thanks to Jotha and Whiskey103 for testing the themes features creating and their first themes for 4EXT Recovery Touch.

Special thanks to Dees_Troy who joined #4ext several times, just to tell me about important things he assumed I didn't know (and he was right! )

Also Big thanks to all the donators to 4EXT Recovery and everyone who has bought 4EXT Recovery Control! Without you I wouldn't be able to spend as much time with the project:



Of course BIG THANKS to KOUSH for ClockworkModRecovery!
Without him, 4EXT Recovery wouldn't exist!

Thanks a lot to the following users for initial testing for specific devices :

Special thanks to Invasion2 and Stlouie65 for spending at least 10 hours of their time helping me debug a really nasty issue on the myTouch 4G!

Also thanks for obtaining calibration values for the touchscreen:
