Samsung GT-i8262 only boots into recovery after flashing I have issue with this phone, flashed the recovery to CWM using the Rashr application and rebooted. Now my phone only boots into recovery anytime I turn it on.

The USB port is damaged, now I decided to flash with CyanogenMod but no avail.
Just remove your battery and  open download mode manually by pressing Power button+Home+volume down key. If you do like this, only then, download mode will support your Odin otherwise, it won’t support. After this just flash your CWM recovery again. 

EDIT: 
You just need to re-flash recovery. In your case, you can use your CWM recovery to flash. I don't remember that it will work. But you can surely flash this
TWRP recovery.

There is a bug which comes in effect if you use reboot from CWM recovery menu. Beware of that bug and reboot manually. 

See this and this for any help about rooting or any problem.
