Why can't Lenovo A66 boot?

I'm sorry for the inconvenience caused to your equipment.

According to the description, the mobile phone can't boot, and it has been stuck in the boot interface. I suggest you try to open the back cover of your mobile phone, remove the battery, and then turn it on to see if you can enter the system normally.

If the problem is still the same, you need to confirm whether you have had surgery before, and what caused the abnormality?

If the mobile phone is abnormal due to deleting or modifying system-related programs or files after brushing the third-party firmware or Root, it needs to be refreshed to restore the use of the system.

Because there are certain risks in self-brushing machine, if you have strong hands-on ability and brushing experience and want to brush the machine yourself, you are willing to take possible risks. Personally, I suggest that you can download the official firmware operation of your device in the firmware area of Lenovo's official music bar.
