Lenovo A710E can t turn on, how to swipe the card, use the third party firmware, and the card is uns

If the Lenovo A710E phone clicks the power button and does not respond and does not turn on, you can use the following steps to make a simple troubleshooting attempt:

1.Caused by poor or abnormal battery contact: It is recommended to reinsert and remove the battery for a restart attempt, if there are other batteries, it is recommended to replace and compare;

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

If the problem still cannot be effectively solved, it is not excluded that it is caused by system problems, physical buttons or related power management and other component failures, due to the risk of flashing the machine and may lead to non-insurance, it is recommended to take the time to flash the machine at a nearby Lenovo authorized maintenance station, and specifically test the hardware.

PS: If you are willing to take the possible risks, you can go to the official Lewen bar firmware area**Official firmware and detailed tutorial, and try to operate according to the flashing tutorial. If you can't handle it by yourself, it is recommended to take the time to go to the Lenovo repair station to deal with it.

1. Possible reasons why the machine cannot be turned on:

The reason is nothing more than two problems: hardware or software, and systems. If there is an external force, such as being dropped, pressed, flooded, overheated, etc., it must be a hardware problem.

2. The solution is as follows.

1.Check your phone's battery first. The reaction when the phone is turned on proves that the battery is still working, and in addition to the aging of the battery and water ingress, the battery problem can be ruled out.

If the battery is aging, you can try it with the same type of battery, and if it can be turned on normally, then replace it with a battery; If it is water, turn on the device when the water has not yet dried, it will cause a short circuit in the battery, and the phone will only run for a while, and the battery will be damaged due to a short circuit, you can wait for a day or two for the phone to completely dry and change the battery.

2.Check your phone screen. Under the destruction of external forces, the screen fails, especially some mobile phones themselves are soldered, which is particularly prone to "fake not booting" caused by the screen.

Although only a slight fall, but the mobile phone screen is no longer responsive due to the disconnection of the line, then you can tap the mobile phone, such as the screen will flash from time to time, proving the problem of a certain line, you can find the broken solder joint after disassembling the machine and re-weld it, or go to the maintenance point for maintenance. Especially when the phone vibrates and sounds normally when it is turned on, but the screen does not respond. This is especially the case for consideration.

3.Check if you can enter the recovery, consider flashing. Both of the above are hardware problems, but the phone can't be turned on completely normally, because there are many software or system problems.

If the phone is just stuck in the logo screen or can not be operated when booted into the interface, then check whether the phone can enter recovery, press and hold the power button + volume down key, if the phone enters the following screen, and can move the cursor by moving the volume + and - keys of the mobile phone, then the phone can be solved by flashing.

Use the flash wizard and select the rom package and you're good to go.
