Now, I need to proceed with the second round of searches to fill in more specific details. I'll search for the history and architecture of FUS, its security features, IMEI requirement changes, region codes (CSC), FUS API documentation, and community discussions. second round of searches provided some relevant results. The search for "samsung fus server history development timeline" was mostly irrelevant. The search for security and IMEI requirements brought up relevant GitHub releases and issues. The search for CSC region codes provided useful explanations. The search for API documentation pointed to a relevant page. The search for Reddit discussions was not very fruitful. The search for XDA Developers forum results provided some relevant threads, including a Frija tool discussion and a general guide. The search for "fota cloud ospserver net" revealed relevant domain information.
