Can't get Clockwork Recovery on my rooted phone

[Guest GoodGosh]

Hi,

 

I have tried everything I've read so far and I still can't get the phone to boot into recovery.

 

I flashed the latest Stock ROM using Sony Ericsson 'Emma' flashtool.  

 

Then I rooted using eroot and I have confirmed the root with the app Root Checker.

 

I installed ROM Manager but it says my device isn't recognised.

 

Also installed X-Parts and even though that said ClockWorkMod install was successful it still won't boot into recovery.

 

I have tried holding down various combination of keys whilst powering up but I don't even see a blue light appearing.

 

Is there any way to get CWM onto my Xperia Arc (LT15i) please? 

 

Thanks for any advice
