How to Flash Firmware on Qualcomm Smartphones with QFIL
FAQs
Q1. What is the difference between the A2017, A2017G, and A2017U models?
The main difference is software and regional network bands. The A2017 (China) has ZTE’s MiFavor UI and no Google apps. The A2017G (Global/EU) and A2017U (USA) have a stock-like Android UI with Google apps. The G and U models also have slightly different modem files for their respective regional 4G LTE bands.
Q2. I have a Chinese Axon 7 (A2017). Can I flash this USA (A2017U) firmware?
Yes. This is the most popular conversion for this phone. Flashing the A2017U firmware onto a Chinese A2017 model is the standard method to get the pure stock Android experience with full Google Play Services. The B35 Nougat build is widely considered to be one of the most stable and popular firmwares for this purpose.
Q3. My phone is on Oreo. Can I use the Nougat firmware to downgrade?
Yes. A full EDL flash using QFIL is the correct method for downgrading your Axon 7. This is often done by users who prefer the stability or battery life of the Nougat builds over the final Oreo release. Remember to back up all your data, as this process will wipe the phone.
Device-Specific Troubleshooting
- Overheating: The Snapdragon 820 in the Axon 7 runs warm. A clean flash of the firmware can sometimes improve thermal management. However, the hardware’s tendency to get hot during intensive tasks is normal. Avoid gaming while charging to keep temperatures down.
- No Sound from Speakers: The Axon 7’s dual speakers are a key feature. If you have no sound after flashing, first check your volume levels and disable “Do Not Disturb.” This firmware will restore the correct Dolby Atmos drivers. If the issue persists after a flash and factory reset, a hardware connection might be loose.
- “No Service” after Flashing: This is the primary risk when cross-flashing. If you flash the A2017U (USA) firmware on an A2017G (EU) phone, for example, some LTE bands might not work. Often, flashing the correct modem file separately can fix this, but it’s an advanced procedure. For best network results, use the firmware matching your phone’s original region.
- How to Enter EDL Mode on Axon 7: EDL mode on the Axon 7 can sometimes be tricky. The standard method is to power off the phone, then hold Volume Up + Volume Down and connect the USB cable. If this doesn’t work, you may need to boot into fastboot and use an `adb reboot edl` command, which is an advanced method.
