Mixed up original and replacement parts after disassembly
Circuit boards and small components look identical across original and aftermarket replacements, making it impossible to tell them apart once mixed up on the workbench. This leads to reassembling devices with the wrong internal board or losing track of whether loose pieces are essential or leftover extras.
What people tried
Every workaround mentioned in the threads below. We haven’t tested any of them — and nobody here is claiming they worked.
