Super slow steam deck rma

Well, just my luck, I got a likely faulty deck that has the throttling issue.

The deck just goes to 200 mhz after a while out of sleep mode. It starts fine then throttles down and stays stuck there. Tried the basic stuff and no go. Reimaging it now to hope it works. Anyone has any other suggestions?

But let's say it doesn't and I have to rma, I have a couple questions to see if anyone has had the same experience.

1. I swapped the ssd to my own 1tb, do I have to swap it back before I RMA?

2. I am also from a non steam deck country and imported it. Any idea if the rma process requires me to send it back to the original country?

Thanks
