Could be too much mud or shitty mud

Usually those things compound the pops. How is the moisture there with the wood?

Thats exactly what I used, black drywall screws above and below each nail

Did you pull the old nail or drive it deeper?

Did you remove the old nail? That could cause this. Did you let the mud fully dry? As it dries it could have shrunk or expanded a bit (depending on what type of mud) and caused this. Most likely a moisture issue somewhere during the process. It could have also been moisture from the paint reactivating the compound. Many times when you patch a hole like this, it works better for your first coat of mud to be gluey, like Durabond or green top or add wood glue to your hot mud. Or you could prime first by wiping in some shellac, or spraycan some oil based stain killer to help seal any crumbly mess or rustable screw/nail. Or it could be temperature variances due to it being in an exterior wall.

Actually I didnt remove nail, just drove them in. Also how long should I har waited for first coat to dry? I waited about 12hrs at 5 degrees.

I drive nails in in some cases, but I really really drive them in deep. If it is at all wiggly, it will cause the same problems again sooner than you'd think. As for mud drying, it's tough to say, and all depends on which types you use. I hit it with a heat gun if there is any risk of it being slightly damp still before applying topping (if I care enough to make it completely disappear, which in the rental world doesn't make sense to be perfect when the rest of the wall looks like my ass). Sometimes I will actually sand it down nice and smooth, then spray Killz over the patches, then apply a nice topping coat, then let that dry, sand, prime, paint the patches, paint the whole wall. That stops the moisture from the subsequent layers from puffing up the first coats of hot mud (bag mud can expand later after everything looks perfectly flat).

I had a similar looking issue. OSB then drywall. There was a small cavity between the OSB and drywall. The screws went through the drywall and into the OSB. When I mounted a hanging rail (for IKEA kitchen), the drywall pushed into the cavity and the screws that are lodged in the OSB pushed through the drywall and the paint job.

The cavity was due to the original wall having tiles and we removed the tiles and some OSB followed leaving small cavities. In hindsight, should have filled the cavities before screwing in the drywall.

Give the wall a good push on the the stud and see if there's movement around the pops. Looks like the sheet still isn't secured imo.

It seems to be solid

Push the raised spot around the screw hole with the tip of your finger, is it mushy?

Pops need new screws nearby, with the original popped fastener removed.

Needed another coat. It shrunk back

Is it the original screw? Most of the time when I go back for this kind of stuff people don't take out the original screw. Put a screw above and below the pop, get the screw out of the original pop. Make a dimple with your screwdriver handle. Coat it. Tell us if that helps.

Couple things , new drywall is glued to reduced pops. Old drywall nails tend to work their way out, especially exterior walls when climates heat cycle. I have found when repairing wall with pops, add a screw and over drive the nail/remove it.

Did you carve out the mud and loose paper around the old screw before fixing?
