How to Flash Firmware on Qualcomm Smartphones with QFIL
FAQs
Q1. My phone gets extremely hot. Will flashing the firmware fix this?
The Snapdragon 615 chipset is well-known for running hot. A clean flash of the stock firmware can resolve any software bugs or rogue processes that are causing extra CPU load, which can help manage temperatures. However, the tendency for the device to get warm, especially during charging or gaming, is a characteristic of the hardware.
Q2. Is this the same as the ZTE Blade S6 Plus?
No. The Blade S6 is the smaller 5.0-inch model. The Blade S6 Plus is a larger 5.5-inch “phablet” version with a bigger battery. Their firmwares are not interchangeable and will brick the wrong device.
Q3. The battery life on my Blade S6 is terrible. Can this help?
A clean firmware flash will resolve software bugs that cause abnormal battery drain. However, the 2400 mAh battery is small for the hardware. After flashing, for the best results, reduce screen brightness and limit background apps. The physical battery will also have degraded due to age.
Device-Specific Troubleshooting
- Performance Throttling (Slowing Down When Hot): This is a built-in safety feature of the phone to prevent the Snapdragon 615 from overheating and damaging itself. A firmware flash ensures this system is working as intended. If your phone slows down dramatically, it’s a sign it’s getting too hot, and you should let it cool down.
- “No Service” or SIM Card Not Detected: This can be a modem software issue. Flashing this stock ROM is the best way to restore the original, stable modem files. If the problem persists after a clean flash, check that the SIM card tray and reader are not physically damaged.
- Stuck on ZTE Logo (Bootloop): A bootloop is a common issue for this model. The most reliable solution is to perform a full firmware flash using the QFIL guide. This will erase all data but will install a fresh, working copy of the operating system.
- QFIL Fails with a “Sahara/Firehose” Error: This classic QFIL error points to a communication failure, usually caused by a driver problem. Reinstall the Qualcomm 9008 drivers (disabling driver signature enforcement in Windows first), use a high-quality USB cable, and ensure the phone is fully powered off before entering EDL mode.
