CN01-02202B booting forever

[alfito]

Hi.
Suddenly my Bluetooth stopped working. It cant detect any devices.
After a factory reset the ubit keeps booting forever.
Is there any way through buttons to force factory reset?
Do I need to flash firmware again? In that case which is the process abd the files needed?
My aliexpress order: 85202208586543

Hi,
Do you mean now the unit stuck in the start logo page?
You can first try to use a stick to click the RST button.

Hello.
I shows bootup logo an then the android animation and keeps there forever.
I have tryed the rst button with no luck. Keeping more than 5 seconds did not make any difference.

Hi,
You can try to connect the key1 or key 2 to the Ground/the metal surface of the unit,then press the RST button.
If this doesn't help you,you can contact the customer service to change an new unit.
