[Q] Unable to enter default Android recovery topic

Hi,

I'm having some trouble entering the default Android Recovery on my S5830i, as it appears to not have it on my model. I've tried holding the Home + Volume up + Power buttons and a combination of others, though nothing works. Holding the Volume up + Volume down + Power buttons enters into download mode, so there's always that.

Can anyone explain how I would factory reset my device without the recovery mode? Is this something that can be done via Odin?

Thanks for your help!
