Q1. My BQ-5201 Space is charging very slowly or not at all. Is the charging port broken?

It could be a hardware issue, as the port can wear out. However, this model also has a known software bug that can cause charging problems. Flashing the stock firmware is an essential first step to rule out a software fault before seeking a physical repair, as it resets the power management drivers.

Q2. The fingerprint scanner is slow and doesn't always recognize my finger. Can this be fixed?

Yes, in many cases. A clean firmware installation restores the original drivers and calibration software for the fingerprint sensor. For the best performance after flashing, be sure to delete your old fingerprints and carefully re-register them in the security settings.

Q3. My phone keeps losing its 4G LTE signal and dropping to 3G. Why does this happen?

This is a common modem firmware issue. Reinstalling the official stock ROM restores the entire radio partition, which includes the baseband drivers responsible for network connectivity. This is a very reliable fix for software-based signal dropping problems.

🔧 Device Troubleshooting

An official OTA (Over-The-Air) update failed and now the phone is stuck in a bootloop: This is a common failure point. The only way to recover from a failed OTA update is to manually flash the full stock ROM using this guide, which will overwrite the failed and corrupted update files.
I get a “PMT changed for the ROM” error in SP Flash Tool: This error means the partition layout on the phone is different from the one in the firmware file, often due to a failed update. To fix this, change the flashing mode in SP Flash Tool from “Download Only” to “Firmware Upgrade” and try again.
SP Flash Tool shows a BROM ERROR or the phone is not detected: This is a driver issue. Ensure the MediaTek VCOM drivers are correctly installed (you may need to disable Windows Driver Signature Enforcement). Use a good quality USB cable and a main USB port on your PC. Make sure the phone is completely powered off before connecting it.
