Cannot enter recovery mode

Hey All,

I have recently rooted my Xperia T2 with hopes of entering the wonderful world of customization. However, I cannot enter recovery mode at all. I have exhausted Google looking for a solution prior to registering here. I have tried everything from downloading apps such as Quick Boot to connecting to PC and trying the adb command ''adb reboot recovery'' and ''adb reboot-bootloader'' and of course I have tried the obvious of turning off the phone and then powering back on while holding the power button and volume up key at the same time. Performing that action shows the phone powering on with the Sony screen followed by a black screen where the phone vibrates 3 times and will continue in this loop if I don't release the keys, If I do release them the phone just starts normally. In all cases, that is is what is happening, the phone restarts and boots normally.

I have checked that everything is OK with the rooting that I did via the app Root Checker and and checked bootloader unlocked status via the command ''*#*#7378423#*#*''.

So, there you have it and I just can't understand why I can't enter the recovery mode. My main goal for the moment is to free up some RAM by doing the Link2SD method but without getting into the recovery mode, that seems hopeless.

Hopefully someone here can advise me.

Thanks for reading and have a great day!
