Bluetooth won't turn on

Hello,

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?

Hi,
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.https://mega.nz/#!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.
Regards
