I can t turn on my Lenovo A789. This is how you can flash your machine

Hello. Sorry to hear that. Due to the brief description of your problem and the fact that we are remote, we are unable to understand the actual doubts you are experiencing, please understand!

You see that the screen is completely black and you can't turn on the phone; Or do you fix the screen after booting up and stay on the page of the company logo when you start up?

If it is the former, it may be caused by poor contact between the battery and the mobile phone, insufficient battery power, or damage to the power and off button;

1. It is recommended to reseat the battery and press and hold the power button to try;

2. It is recommended to use the standard charger to charge for 30 minutes, and press and hold the power button to try;

3. If it is invalid, it is recommended that you contact the official site for testing and processing in time;

If the latter is the case, there may be two main factors that lead to this situation: 1. The file of the system is abnormal, and 2. The boot data of the motherboard is abnormal or missing.

It is recommended that you can reseat the battery, press and hold the power button to try, if it cannot be improved, it is recommended that you contact the after-sales site in time for detection and treatment.

If you need to flash the upgrade, because there is a certain risk in flashing the machine by yourself, and the failure to flash the machine may affect the warranty status of your device, it is officially recommended that you can go to the local maintenance site to flash the machine.

The firmware package has a detailed tutorial built-in, please be careful. If you really can't complete it by yourself, we recommend that you go to Lenovo repair station to flash the machine and test the whole machine specifically.
