Many PS2251-07 drives ship with buggy firmware that keeps the drive in "performance mode" constantly. Using Phison’s MPALL tool (Mode Converter), you can flash firmware that enables "power saving" or "USB 2.0 fallback."
The initial bootloader binaries used to initialize the controller.
No dedicated academic "paper" specifically focuses on heat issues for the , but the technical community has documented this controller's tendency to overheat, especially when it enters a "firmware panic" state. Why Phison PS2251-07 Gets Hot

: Persistent overheating in devices without adequate cooling can eventually lead to firmware corruption or physical failure of the controller.
For comparison, Phison’s higher-end controllers like the PS2251-08 (PS2308) offer dual channels and reach 400/300 MB/s sequential read/write, but the PS2251-07 is not designed for such performance levels.

If software fails to recognize the drive, manually triggering "test mode" on the PCB (shorting specific pins) is often the only way to force the controller into a state where it can be reflashed.
Troubleshooting the Phison PS2251-07 (PS2307) Overheating Issue
However, users must be aware of its quirks: the tendency to enter write-protected states, the physical heating during sustained operation, and the risk of permanent bricking during improper firmware updates. Fortunately, the MPALL mass production tool provides a robust recovery path for most software-related failures. Why Phison PS2251-07 Gets Hot Download the tool
If you have a rugged or thick plastic flash drive casing, it acts like a blanket keeping the heat in. If the data on the drive is vital and the drive keeps dropping connection due to heat, carefully crack open the plastic casing using a small pry tool.
If you encounter a “hot” PS2251-07 drive that refuses to format or write, remember: with the correct firmware is your most reliable solution. Just be sure to back up your data first, and never interrupt the mass production process.
Before opening up the casing, diagnose how the hardware behaves when plugged in. Do not leave the drive plugged in for more than 1–2 minutes if it is overheating violently.
