Bluetooth won't turn on

My bluetooth stopped working some time ago and wouldn't turn on. This happened on a previous version of android on the same device, but upgrading the device seems to have resolved the issue temporarily.

My bluetooth stopped working again a few weeks ago and in an attempt to fix it I used the Backup & Restore function, which did not resolve the issue, I have tried wiping all the data and cache, I even tried a few "Bluetooth Fix" apps. I have spend a fair number of hours trying to resolve the issue, but no luck. Bear in mind that I did not touch the hardware and I believe it is purely software problem.

The bluetooth was working PERFECTLY fine up until one day I go to the gas station to re-fuel. After coming back and turning my car on it was no longer working and I haven't been able to fix it. Any ideas?

you can first enter settings - factory settings(password :126) and check whether Bluetooth module is WQ-BC6.Then click apply and exit button one by one.

If it didn't help, you can try to flash this firmware.!3CA0zCJY!qgJ56fncDIcq ... G1UKnFG66g
Please download it to the root content of one sd card and insert it into the GPS slot.Then enter settings - about device - system update.

The 2nd option worked.
