Now senior XDA developer, emwno, has shared a ClockworkMod (CWM) Recovery file for Samsung Galaxy S4 I9500 model allowing users to install CWM on their devices. The package, which is still in its development stage, is reported to be working fine.

The developer has also shared the stock recovery file. If users come across any issue with the custom file and wish to return to the stock version, they may install the stock recovery using Odin flashing tool. Head over to the development page to learn more about the CWM recovery file.

A custom recovery like CWM serves multiple purposes. Using the custom recovery users can install custom ROMs, root their device, create Nandroid backup and restore the phone. Additionally, it enables installation of various system tweaks.

Galaxy S4 users who wish to install CWM Recovery on their devices may follow our step-by-step guide below.

IBTimes UK reminds its readers that it will not be held responsible for any damage to the device. Before following the installation guide, users are advised to ensure that their devices meet the below-mentioned requirements.


1) Download and install USB Driver for Samsung Galaxy S4 to connect the Android device with the computer.

2) Ensure that USB Debugging Mode is enabled on the phone to connect it with the computer and use the Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option and ensure the USB Debugging Mode is turned on.]

3) Create a backup of all the data of the phone. If the device is having a custom recovery such as CWM/TWRP installed, then back up the data using the same since it creates a complete image of the existing phone set up.

4) The Galaxy S4 should have above 80 per cent of charge.

5) The device should be factory unlocked and not locked to any particular carrier.

6) The CWM Recovery file is compatible only with Samsung Galaxy S4 I9500. Do not flash this package on any other variant. Verify the model number of the device by selecting Settings>> About Phone.
