How to enter recovery mode?

[惜今bu惜昨]

Must I connect to a PC while doing this? And I have auto blocker turned on, will this prevent me from entering recovery mode? I want to clear cache.

Not sure about auto blocker.
But you will need to connect to either a computer, or a TV port
I've conneted to another phone before

Yes you need to connect to either a PC or another (Samsung?) Device to enter Recovery Mode.

I don't think auto blocker will impact.

I have checked and the Auto Blocker does  not impact on wiping the cache partition.  It Blocks commands and software installation via USB  cable.
