Departing ZZZ; the Captain and I heard a loud popping sound on FO (First Officer) side and EICAS showed Pack 2 valve closed. The Captain ran the QRH as specified; recycled the pack and EICAS message went off and a few minutes later it came back with cabin pressure rising rapidly. The Captain ran QRH as specified at the same time we were getting Packs 1-2 valves closed and were alternating on our way down. We [advised ATC] and came back to ZZZ and deplaned normally. A non-rev pilot came to us after deplaning and told us he heard a loud pop in the back and a rush of air in the cabin.Suspected bleed air leak.
On climb out from ZZZ; we had a PACK 2 bleed closed message. We attempted to open the valve using the QRH procedure and it did not work. A few minutes later we saw that the cabin altitude was climbing rapidly and we then saw PACK 1-2 valve closed message. We asked to remain at 10;000 ft. and ran the QRH and were unable to get either valve to open and therefore unable to pressurize the cabin. We [advised ATC] and decided to return to ZZZ. We landed and deplaned without any further issues. Later we were informed by a non-rev pilot that he heard a loud air sound on the climb out and he suspected a bleed air leak.
ERJ-145 First Officer reported bleed air and air conditioning/pressurization issues with aircraft and elected to return to the departure airport.
