    Question: Will flashing a CWM wipe all my data? If it does, how would I go about backing it all up so I can quickly and easily restore my phone to where it was before the CWM?

    • Mahesh Makvana

      Flashing CWM doesn’t wipe the data on your device. It just replaces the stock recovery with CWM, that’s all.

      Thanks Stephen!

    Also, the adb isn’t being recognized as an internal or external command. Help?

    • Mahesh Makvana

      Such error occurs when you do not have ADB.exe file in the directory where you’ve opened the Command Prompt Window, in this case, it’s your Desktop.

      Make sure that you’ve ADB.exe file on your Desktop and you’re opening the Command Prompt Window just as I said in Step-6.

      It should solve your problem!

  • Steve Arino

    The first command does not work cannot stat ‘cmwrecovery.img’ no such file or directory.

    • Hey Steve,

      What’s the name of the recovery file you extracted from the archive? Is it cwmrecovery.img?

      • Steve Arino

        I didnt see any .img files in the archive.

        • Steve Arino

          I think the download provided is the wrong one.

          • Hey Steve,

            Download link for the cwmrecovery.img is located in the first post of the source thread. Just click on “Recovery Package” link and you’ll be taken to the original thread from where you can download the recovery for your device.
