If you're playing the Cyberpunk 2077 game and you've come across cyberware mods that you can't equip or sell, there are a few solutions to this problem. The first solution is to visit a ripperdoc. A ripperdoc is a specialized doctor in the game who can install cyberware and other implants in your character's body. It's possible that the game didn't inform you about this requirement when you selected the cyberware mod, but it's important to seek out a ripperdoc to have the mods installed. This will allow you to equip or sell the cyberware mods.
The second solution is to ensure that you have the necessary base cyberware to install the mods. Some cyberware mods require a specific type of cyberware to be installed first. For instance, if you want to install a mod for a cybereye, you must first have the base cyberware installed. To check if you need to acquire any additional cyberware, you should review the requirements for each mod you have in your inventory.
The third solution is to acknowledge that cyberware mods were removed in the 2.0 update. Depending on what the mods are, they may no longer be available in the game. To check if cyberware mods were removed in a recent update, you should review the game's update history. If they were, you'll need to find a different solution to equip or sell your cyberware mods.
In conclusion, if you're having trouble equipping or selling cyberware mods in Cyberpunk 2077, you should visit a ripperdoc, ensure that you have the necessary base cyberware, or acknowledge that cyberware mods were removed in the 2.0 update. By following these solutions, you should be able to equip or sell your cyberware mods and continue enjoying the game.
