Q1. My phone is completely dead and won't turn on, but my PC recognizes it. Can this fix it?

Yes, this is the exact purpose of this guide. Your phone is in EDL (Emergency Download) Mode. Following the QFIL flashing instructions is the standard procedure to unbrick and restore a hard-bricked Qualcomm device like the BQS-5025 Highway.

Q2. My phone keeps rebooting randomly. What is the cause?

Random reboots are typically caused by software instability, which is common on devices with 1GB of RAM. A clean flash of the stock firmware will resolve these software conflicts and restore system stability by reinstalling the entire operating system.

Q3. The phone sometimes shows "No SIM Card" even though the SIM is inserted correctly. Will this firmware help?

It often can. This issue is frequently caused by a corrupted modem or baseband file within the software. Flashing the stock ROM completely reinstalls these network-related files and is a reliable fix for software-based SIM detection problems.

BQ Mobile BQS-5025 Highway Firmware (Stock ROM)

The BQ Mobile BQS-5025 Highway is a 4G LTE smartphone from 2016 powered by a Qualcomm Snapdragon processor and running Android 6.0.1 Marshmallow. This device is particularly known to suffer from software issues that can lead to a “hard brick” state, where the phone becomes completely unresponsive but is still detected by a computer in EDL mode. Other common user-reported problems include random reboots and the phone failing to detect a SIM card. For users facing these issues, especially a dead or bricked device, flashing the official stock firmware using the QFIL tool is the primary method of recovery.

ℹ️ Important Note:
This phone is powered by a Qualcomm Snapdragon chipset and requires the QFIL (Qualcomm Flash Image Loader) tool. This process is often used to unbrick devices stuck in EDL Mode (Qualcomm HS-USB QDLoader 9008) and will completely erase all your personal data.

Backup Your Data: If your phone is still accessible, back up all personal files, as this process will wipe the internal storage.
Charge The Battery: Ensure the battery has at least a 50% charge to prevent shutdowns during flashing. If the phone is bricked, charge it for an hour before starting.
Windows PC & USB Cable: You will need a Windows computer and the phone’s micro USB data cable.

Quick Steps to Flash BQS-5025 Highway Firmware

Download and install the Qualcomm HS-USB QDLoader drivers on your PC. Extract the firmware file (BQ_BQS-5025_..._QFIL.zip).
Power off your phone. Boot it into EDL Mode by holding both Volume Up + Volume Down buttons simultaneously and then connecting it to the PC with a USB cable.
Launch the QFIL tool. The top of the window should show a port named “Qualcomm HS-USB QDLoader 9008.”
Under “Select Build Type,” choose “Flat Build.” Click “Browse” next to “Programmer Path” and select the prog_emmc_firehose_...mbn file from the firmware folder.
Click “Load XML” and select the rawprogram_unsparse.xml file, followed by the patch0.xml file.
Click the blue “Download” button to begin the flashing process. Disconnect the phone after you see a “Download Succeeded” message.

🔧 Device Troubleshooting

QFIL is not detecting the phone or shows “No Port Available”: This is a driver issue. Ensure you have correctly installed the Qualcomm HS-USB QDLoader drivers. You may need to disable Windows Driver Signature Enforcement during installation. Also, verify you are entering EDL mode correctly (hold both volume buttons *before* connecting the cable).
The flash fails with a “Sahara” or “Firehose” error: These are common QFIL errors that can be caused by a bad USB port, a faulty cable, or incorrect drivers. Try using a different USB 2.0 port (not a hub), use a high-quality data cable, and run QFIL as an administrator.
The phone overheats, especially when using 4G data: A clean firmware flash can help by removing any background processes that cause extra CPU load. However, the Snapdragon 210 chipset is known to be inefficient and run warm. After flashing, reducing background data usage and screen brightness can help manage temperatures.
