Troubleshooting Common Problems
Even after flashing the official firmware, users may encounter certain issues. Below are the most frequent problems with the BQ Shark Rush BQ-5541L and their solutions.
1. Bootloop After Flashing
If your BQ Shark Rush gets stuck at the logo after flashing, it may be due to mismatched firmware or corrupted userdata. The solution is to repeat the process in SP Flash Tool, this time selecting Format All + Download (note: this erases IMEI and requires backup).
2. Network or SIM Card Not Detected
Sometimes the IMEI can be lost during flashing. This results in no network signal. You can restore IMEI on the BQ Shark Rush using the Maui Meta Tool or SN Writer Tool with your device’s original IMEI number.
3. Fast Battery Drain
A common issue after flashing is abnormal power consumption. This usually happens if you did not perform a factory reset after installation. Enter recovery mode and wipe cache/data to stabilize battery performance.
4. Camera or Sensors Not Working
If the camera app crashes or sensors malfunction, double-check that you used the correct firmware build for your exact device variant. Installing the wrong ROM build can cause hardware incompatibility. Reflash with the SW10_190807 package provided here.
