Forum Lenovo Community:

I'm sorry to affect your use, have you accidentally pressed the volume button + power button to enter the engineering mode, it just prompts "Enter the engineering interface, long press it will turn on normally......"If it's this place, you can let go of your hand and hold down the power button to get in.

If you are already in the project mode interface with a lot of English words, you can use the volume button to select reboot, and then click the home button to confirm that you can reboot into the system.

If you enter the mode every time you turn on the machine, it may be that the volume button, photo button and other keys are abnormal or the system is abnormal, it is recommended that you take the time to bring the warranty card or invoice to contact the local maintenance site for further testing and processing. Inquire about authorized maintenance sites on the official website.

Press and hold the volume plus or minus keys at the same time when you turn on the machine, and then let go of the logo to enter the engineering machine mode. But if you want to flash the phone or something, press and hold the volume plus or minus button and the home button at the same time when you turn on the phone to enter recovery mode. Try a few more times and get in.

Since there is a certain risk in flashing the phone by yourself, and the failure to flash the phone will affect the warranty of your phone, we recommend that you can take the time to go to your local Lenovo after-sales service center and let the engineer help restore the system to use. You can log in to the official website to check the address.

Dear Lenovo users, hello!

When the phone is turned off, press the power button + volume button at the same time to enter recovery.

Hello. Sorry, the boot is abnormally entering engineering mode, which may be caused by the combination of the power button and the volume button accidentally pressed before, or the system is abnormal.

It is recommended that you try to force the shutdown (such as removing the battery, pressing the reset button, pressing and holding the power button, etc.) and restart it. Note: You can't press the phone's volume keys at the same time.

If the boot automatically enters the engineering mode frequently, it is recommended that you back up the important data of the lower fuselage, and then restore the factory settings to see if it can be improved.

If the problem persists, it needs to be sent to the repair station for testing and solving.

Do you think that by saying this, you will attract God-men?

Dear Lenovo users, hello!

If your Lenovo phone A789 has been in engineering mode when it is turned on, it is likely that you accidentally pressed the power and volume buttons together, it is recommended to restart the phone and do not click the volume side button to try.

If it doesn't work, you can reinstall the system by swiping the method, usually recovery is a line brush to enter, if you have swiped a third-party recovery before, try to flash the machine by retrieving the official flash and tutorial.

However, there is a risk in flashing the phone by yourself, and the failure to flash the phone may lead to the failure of the mobile phone and the loss of warranty service, it is recommended that you do not try it easily, you can take the time to bring the warranty card or invoice to contact the local maintenance site to operate.

Is it that your phone's keys are stuck?

1. If the boot is abnormally and enters the engineering mode, it may be caused by accidentally pressing the combination of the power button and the volume button before, or the system is abnormal.

2. If the screen only prompts "Enter the project interface, long press will boot normally......"If it's this place, then let go of your hand and hold down the power button again to enter.

3. If you have entered the project mode interface with many English words, then use the volume button to select reboot, and then click the home button to confirm.

4. If it still doesn't work, you can force the shutdown, that is, directly deduct the battery to restart it.

5. If the boot automatically enters the engineering mode frequently, it is recommended to back up the fuselage data (to avoid the loss of important data), and then restore the factory settings to see if it can be improved.

If the problem persists, you need to take the time to send it to the official repair station for inspection and processing.

Dear users, hello!

This is the Lenovo FAQ knowledge base, which has a relatively complete answer and know the process and analysis:

If you enter the engineering mode and want to clear data, this operation will erase all data (contacts, call information, etc.) in the storage of your device

a.After the phone is completely turned off, press and hold the power button and the photo button at the same time until you enter the recovery interface and release the button;

b.In this interface, the volume button can be used to move the options, and the four-leaf clover button at the bottom of the screen is the confirmation button, which moves the options to Clear eMMC separately for confirmation.

After the operation is complete, you can restart and clear the data operation. If you are unable to do it yourself, it is recommended that you take the time to go to the workshop and have an engineer assist you in handling the problem.

Officially authorized repair site inquiry:

Hello. If you accidentally enter engineering mode, it is recommended that you try to remove the battery and force it to shut down and restart it. Note: You can't press the phone's volume keys at the same time.

If you turn on the machine many times and automatically enter the engineering mode, but now you can enter it normally, it is recommended that you operate the important data of the backup body and then roll the stove, and restore the factory settings to see if it can be improved.

If the problem is still there, and now you can't enter the system, you need to send it to the repair station for detection and solution, and it is not excluded that it is an abnormal button or a system abnormality. System abnormalities require flashing and specific detection. Due to the risk of flashing the machine and may lead to non-insurance, the official does not recommend that you deal with it by yourself, please take the time to go to the repair station to be assisted by the engineer to assist you in testing and processing.
