Older or poorly modified firmware builds lack proper CPU frequency scaling rules. Instead of dynamically lowering clock speeds when idle, the firmware keeps the hardware in a high-power state. Buggy releases (like some raw implementations of custom Version 9 firmware) can also get stuck in infinite logic loops—such as failing to commit Wi-Fi password changes to the flash memory—which elevates processor heat. Poor Environmental Placement
When users search for , they are usually dealing with two correlated issues: thermal overheating caused by dense routing loads, and "hot" (trending/modified) English firmware versions compiled to unlock the advanced carrier settings of this China Mobile device.
