      Root your phone using unlockroot, then try. you will see all the options.
      install rom manager after rooting it, you will be navigated to recovery mode easily

      dont use ROM manager for CMW 10, install SDK and install ADB on ur pc or use terminal emulator intead and follow copy paste instruction in ADB or terminal emulator Just like the previous method, this method also requires following advanced steps and is not recommended if the first method is working for you. flash_image is a tool for Android devices that lets you rewrite your phone’s system partitions with partition image files and installing it to your device requires ADB. If you don’t already have ADB installed, check out our guide on installing ADB. Once you have ADB installed, flash the custom recovery image as follows:

      WARNING: It is very important that the recovery image that you use in this method is compatible with your device. Else it will not work and flashing it could possibly brick your device.

      Download flash_image and extract it from the zip file to a location on your computer. We extracted it to the main C drive (not in any folder) and will use that in the next steps.
      Copy the recovery image for your phone to a convenient location on your computer, preferably with a short path. We will be placing it on the C Drive directly (not in any folder) and using that in the next steps.
      Note: The recovery image should have .img extension. If it is in a zip file, extract the .img file from it.
      Enable USB debugging mode on your device from Menu > Settings > Applications > Development.
      Connect your device to your computer via USB.
      Open a Command Prompt window on your computer and enter the following commands:

      adb push c:\flash_image /sdcard/
      adb push c:\recovery.img /sdcard/
      adb shell
      su
      mount -o remount, rw /system
      cp /sdcard/flash_image /system/bin
      cd /system/bin
      chmod 777 flash_image
      flash_image recovery /sdcard/recovery.img

      This will first transfer flash_image and recovery.img to your phone. Then it will copy flash_image to the /system/bin folder of your Android device and make it executable. Finally, it will flash the custom recovery image to your device using flash_image.
      Note that we used c:\flash_image and c:\recovery.img in the first two lines as we had these files extracted at the root of our C drive. If you extracted the files elsewhere, use the appropriate paths and if your recovery image has a different name, use the appropriate name. this method worked for me fine ..
      FOLLOW the above steps carefully read it twice at ur own risk dont blame me if u brick ur phon. lets hope it doesnt brick ur PHONE
