Many users report their CPH2357 (an OPPO/Realme model code) getting unusually hot — especially after updates, heavy apps, or failed firmware installs. Flashing the device with the correct firmware can often resolve persistent overheating caused by corrupt system files, bad firmware variants, or runaway background processes. This guide walks you through what flashing does, how to choose the right flash file for CPH2357, how to prepare, and step‑by‑step flashing instructions and troubleshooting. Follow carefully — flashing can fix many problems but can also brick your phone or void warranty if done incorrectly.
