Q1. Can I use this firmware to upgrade my phone to a newer Android version?

No. This is the official Android 7.0 Nougat firmware, which was the final OS version officially released for the BQ-5044 Strike LTE.

Q2. I'm getting a "BROM ERROR" in SP Flash Tool. What should I do?

BROM errors typically indicate a communication failure between the PC and the device. The most common causes are incorrect VCOM drivers, a faulty USB cable, or an unstable USB port. Re-install the drivers, try a different cable/port, and ensure the phone is completely powered off before connecting it.

Q3. My phone's IMEI is showing as "Invalid" after flashing. How can I fix this?

An invalid IMEI is caused by erasing the NVRAM partition, which happens if you use the "Format All + Download" option in SP Flash Tool. This stock firmware, when flashed in "Download Only" mode, will not restore a lost IMEI. You will need a separate, more advanced tool like Maui META to write your original IMEI numbers back to the phone.

Q2. I’m getting a “BROM ERROR” in SP Flash Tool. What should I do?: BROM errors typically indicate a communication failure between the PC and the device.

Re-install the drivers, try a different cable/port, and ensure the phone is completely powered off before connecting it.

🔧 Device-Specific Troubleshooting

Phone Not Detected by PC: If the flash tool doesn’t respond when you connect the phone, it’s a driver or connection sequence issue. Re-install the VCOM drivers. Then, click “Download” in the tool, press and hold the Volume Down button on the phone, and then connect the USB cable. This often forces the device into the correct flashing mode.
“PMT changed for the ROM” Error: This partition error can occur if the existing software on the phone has a different layout from the firmware you are flashing. 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.
4G/LTE or SIM Card Not Working: After a successful flash, if you have no mobile network, first check that your SIM card is inserted correctly and that your APN settings are correct for your carrier. If the IMEI is valid and settings are correct, a corrupted modem file could be the issue. Re-flashing the firmware in “Download Only” mode can resolve this.
Stuck on BQ Logo After Flashing: If the flash completes but the phone won’t boot, you must perform a factory reset. Power off the device, then boot into recovery mode (usually by holding Power + Volume Up). In the menu, select “wipe data/factory reset,” and then reboot.
