Proudly presenting:
4EXT Recovery Touch

  • brand new user interface: "4EXT UI"
  • touchscreen only
  • extremely fast
  • much more useful features than the already feature-packed 4EXT Recovery Classic v2.2.7 RC5 (see 2nd post)
  • 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


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.

If you somehow lost those files, there's a direct download for a version you can flash via fastboot.

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

    -> so that after a restore, all partitions and up with the file system you wanted!

  • Integrated md5sum checking option

  • Format menu
  • Power Menu + option to reboot into bootloader

Recovery Interface Api for Apps and Scripts

Both: free and paid 4EXT apps now provide a very easy to use interface you can use to access 4EXT Recovery from within your shell scripts or apps.

  • wipe cache
  • wipe dalvik
  • wipe data / factory reset
  • install multiple zips at once
  • backup

If you are interested, please download this zip file with examples

How to make use of 4EXT Recovery Touch from within updater-scripts:

Since Beta Beta 4 you can do the following:
  • identify whether the user is running 4EXT Recovery Touch or not (to use or not to use the following commands)
  • make use of the native yes/no dialogue (confirm / cancel buttons)
  • prevent recovery from redrawing the screen ( in case you need to use your own 3rd party interactive binary )

To identify 4EXT Recovery Touch:

if getprop("ext.edition") == "ng" then

<your code>


To use the native confirm dialogues:

ui_print("4ext: show_yesno"); # <-- recovery will pause your script and display "yes / no" buttons.
run_program("/sbin/sleep", "2"); # <-- for safety since the above is executed asynchronous 

#check the return value by calling:

if getprop("ext.confirm") == "yes" then



To prevent recovery from redrawing the screen ( if you want to use an external binary that needs to occupy the screen and get the focus )

ui_print("4ext: disable_scrn_update");

# don't forget to enable it again after your yesno binary or graphical installer is finished, by calling:

ui_print("4ext: enable_scrn_update"); #otherwise the recovery will appear to be frozen as it won't update the screen anymore.

Quoted from original post:

Recovery is currently being compiled, app v2.1.4 is being finished and all should be available within the next 30-60 Minutes.

Edit: too late :P
