Q1. Why are my selfies blurry even with the front flash? Will this firmware help?

This firmware can fix software processing issues, but the BQS-5050 Strike Selfie uses a fixed-focus front camera. For the sharpest results, hold the phone at about arm's length. If photos are still out of focus, a clean flash is a good step, but also ensure the camera lens is clean and not scratched.

Q2. Can I use this firmware to upgrade my phone to Android 7.0 (Nougat)?

No. This is the official Android 6.0 Marshmallow firmware. No official updates to newer Android versions were released by BQ Mobile for this model.

Q3. I'm getting a "PMT changed for the ROM" error. What should I do?

This partition error can occur if the phone's storage has been previously formatted with a different layout. To fix this, change the flashing mode in SP Flash Tool from "Download Only" to "Firmware Upgrade" and try again. This will erase all data and correctly reformat the partitions.

BQ Mobile BQS-5050 Strike Selfie Stock Firmware (Flash File)

The BQ Mobile BQS-5050 Strike Selfie is a 5.0-inch smartphone from 2016, aimed at the Russian and CIS markets. As its name suggests, it was marketed for its front-facing camera, which is uniquely paired with its own LED flash. If your BQS-5050 Strike Selfie is bricked, stuck in a bootloop, or has become unusable due to software errors, flashing the official Android 6.0 Marshmallow stock firmware is the definitive method to restore it.

🔧 Device-Specific Troubleshooting

Front LED Flash Not Working: The key feature of this phone is its front-facing flash. This firmware restores the original drivers. If the front flash does not activate in the camera app’s selfie mode, test it by downloading a “Flashlight” app from the Play Store that can specifically control the front LED. If it still fails to light up, it is likely a hardware issue with the LED itself.
Erratic or “Ghost” Touches on Screen: Some users of budget devices from this era reported unresponsive or “ghost” touches. A clean firmware flash is the best first step to rule out software or driver corruption. If the problem persists after a successful flash and factory reset, it strongly suggests a failing digitizer (the touch-sensitive layer of the screen).
Phone Not Detected by PC: The removable battery simplifies this. If the phone isn’t detected, the issue is almost always the VCOM drivers. Re-install them correctly. Then, click “Download” in SP Flash Tool *before* connecting the phone (without its battery) to the PC to ensure it’s in the correct state for flashing.
Invalid IMEI After Flashing: This critical error is caused by erasing the NVRAM partition, which happens if you use the “Format All + Download” option. To protect your IMEI, always use “Download Only” mode. If the IMEI is already lost, it must be restored using a separate tool like Maui META.
