Samsung Galaxy Grand Duos: Odin flashed the custom Recovery but device boots into stock Recovery I am new to rooting Android. I tried using Odin 3.10 to root my Samsung Galaxy Grand Duos. I successfully flashed CWM (Odin displayed pass message). However when I restart phone in Recovery mode, it shows Android with an error symbol, and then loads the stock Recovery.  

I am trying to flash CM12. What's the issue, and how do I fix it because I want to root my phone.
Before you flash the recovery, untick the Auto Reboot option in ODIN. Then flash the recovery. After flashing in done, reboot your device directly to recovery mode from download mode bu pressing Vol up + Power + Home button together. Now you will see the CWM recovery is booted in your device. Now you can reboot normally and your CWM will be installed.
