"Why is my PS5 controller update getting stuck and how can I fix it?"
When a PS5 controller is updating, it's not just downloading new data, but also rewriting the firmware, which is the software that controls the device's hardware components.
This process can be prone to errors.
The "starry dots and ethereal music" screen is likely a manifestation of the controller's boot loader, which is a small program that runs before the operating system loads, and is responsible for initializing the hardware components.
The reason why restarting the console or resetting the controller often fixes the issue is that it allows the device to reload the firmware and restart the update process from a clean slate.
Firmware updates can get stuck due to corrupted data packets during transmission, which can be caused by issues with the internet connection or the server hosting the update.
When a PS5 controller is connected to a PC, it uses the USB protocol to communicate, which can be affected by the quality of the USB cable, the USB port, and the PC's USB controller.
The DualSense controller uses a custom-designed USB-C connector that supports data transfer rates of up to 480 Mbps, which is faster than the typical USB 2.0 standard.
The PS5 console's operating system is based on the FreeBSD kernel, which is a Unix-like operating system that is known for its stability and security features.
When the PS5 controller is updated, it's not just the firmware that's being updated, but also the device's boot loader and other low-level software components.
The PS5 controller's firmware is stored in non-volatile memory, which means it retains its data even when the device is powered off.
The "stuck" update issue can be caused by a corrupted or incomplete firmware image, which can be solved by reinstalling the firmware or using a different update method.
The PS5 controller's firmware update process involves a process called "firmware flashing", which rewrites the device's firmware with new data.
The reason why some users have success with using the USB cable that came with the controller is that it's designed to support the high-speed data transfer rates required for firmware updates.
The PS5 controller's update process involves cryptographic verification to ensure the integrity and authenticity of the firmware image, which can sometimes cause issues if the verification fails.
The "infinite loop" issue where the controller becomes stuck in an infinite loop can be caused by a faulty or corrupted firmware image, which can be solved by reinstalling the firmware or resetting the controller.
The PS5 controller's firmware update process involves a process called "error correction", which detects and corrects errors in the firmware image during transmission, but can sometimes fail if the errors are too severe.
