The procedures outlined below should be done as carefully as possible. I will not be held responsible if something goes wrong, nor will anyone else involved with discovering this information. Proceed at your own risk.
To follow this guide you will want to be comfortable with opening small devices and connecting circuits. If this thought scares you, do not proceed. Bandai will not replace your device if you break something, and parts aren’t easy to come by, so BE CAREFUL. If you’ve never opened a Pen20 before, watch this video first. https://youtu.be/0akUj9rSNn0
The image above displays the connections on a Silver Blue device. They are labeled JP1, JP2, JP3 and JP4. JP1 will not be used for getting eggs, ignore it for now. You will notice that JP2 is filled in, and JP3 is not. This is what makes this device a Silver Blue. When JP2 is not filled in, Odd eggs are used (NSp, NSo, Mem, etc...), and when JP2 is filled in, Even eggs are used (DSa, WGu, VBu, etc…). When JP3 is not filled in, the device is a Wave 1, and when it is filled in, it is a Wave 2. The only difference between Wave 1 and Wave 2 is whether getting 35 Digimon in your album unlocks Terriermon/Lopmon or Zubamon/Dracomon.
Switching versions by itself does NOT unlock any eggs. Eggs are still unlocked for fulfilling requirements on each version. If you only have 3 eggs on a Silver Black and you turn it into a Silver Blue, you will only get the three default Silver Blue eggs in addition to your current 3 eggs. It’s a good idea to unlock all eggs before you start!
The key to this whole guide is connecting the two silver bits in a section together, and removing connections when necessary. I am not going to tell you how to fill the connections on your device, but I will tell you what people have used:
If you have a have a soldering iron with appropriate material for use on circuit boards, use it. If not, get one, they are relatively cheap. The temporary solutions should be seen as temporary, not permanent. They may loosen or wear over time AND MAY DAMAGE YOUR DEVICE!!! After unlocking every egg, you may want to consider removing them or replacing them with solder do get your preferred final version. As long as you keep your save file and have every egg already, your final version won’t matter.
I’m not going to tell you how to remove existing connections, that is terrifying and if you don’t already know how, you probably shouldn’t do it without a bit of external research.
This guide begins with a Silver Black device. If you want to use a different device, the same general instructions can be followed, just start from the appropriate step and loop back to step 5 after finishing step 35. Silver Black does not have any JP connections filled, which is why it is easiest to start with. If you use another version, you will need to remove an existing connection at some point during this guide. Default Version IDs are as follows:
Silver Black - 2A00
Silver Blue - 2B00
Dukemon - 2B10
Beelzebumon - 2A10
This is where JP1 comes in. JP1 determines whether or not your device is in Debug Mode. You can verify this on the version screen by seeing if you have a big DEBUG banner on it. If so, you get the following 2 abilities.
Harun Al Rasyid for enlightening everyone about the JP connections
BetamonZ and arararin from the DDC, for getting their hands dirty and testing like every possible combination
@nazirulnoor and @Eyymaann of Uthara Tamers, as well as Pidot Redmist, Izar Omar, Syahrul Mezan, and Abdul Azzim for discovering how debug mode works.
Me, humulos, because I wrote these words you are reading, YEAH!
