I've done the exact same thing for the exact same reason. The guide does not match the kit that I was set and all that it says for fitting the regular is "Be careful to turn it on the right side!". Not being familiar with electronics and using this as a learning experience (as advertised), I'm not too happy that I now have a useless device. I have a solder sucker, but it's not doing the job as far as I can tell (I've never had to use it before). I've let the iron get really hot and tried to apply to all 3 pins to allow for some movement but no luck. Just a few burnt fingertips trying to move it.
I wouldn't advise any beginners to start working on this project until the guide has been completely rewritten so that it matches the kit that has been sent out and clear and accurate photos exist for each step, since this is what we need to follow. As a backer, I realize that the kit wasn't too expensive, but I was honestly excited about this project and now it's worthless if I cannot fix this honest mistake. All because I had to make a 50/50 guess as to how to what the "right way" was and, unfortunately, I made the wrong one.
I'm very disappointed this whole experience, to be honest. I was going to get another after this one for my partner, but I'm reluctant to hand over any more money to this project. Documentation is key and it feels out-dated and lacking in some key areas. I'm going to try desoldering again tomorrow, with a clear head, but I don't have much hope that it's going to work.
I only noticed at the stage where I had to turn it on for the first time. Nothing happened and I knew immediately that I must have made the wrong choice at this step. I've since looked up the piece online and found a simple diagram that showed the 1 2 3 numbers mapped to pins based on the top shape. This would have been perfect to see in the guide, to help others avoid wrecking their device too.
