Lenovo p780 hangs on the splash screen. Lenovo p780 does not turn on: causes of malfunction. Reasons for smartphone freezing

Many owners of a Lenovo P780 smartphone running Android are faced with problems in which the phone does not turn on. This happens both after certain actions and during normal operation of the device. During our article, we will talk about the main causes of the problem and several troubleshooting methods.

Why Lenovo P780 4Gb does not turn on

There are many reasons why a device may not function properly; problems often arise during everyday use. According to technicians and representatives of device manufacturers, startup failures may be associated with the following events:

• after updating the operating system, some system files were installed with errors;
• the device stopped loading due to viruses that came with applications installed not from the Play Market;
• after falling on a hard surface, the display or battery cable is disconnected;
• The USB connector is clogged or small but harmful rust stains have appeared on the contacts due to moisture.

It’s worth noting right away: coping with mechanical damage on your own is not easy. During home repairs, you can inadvertently break any connections, thereby making your smartphone beyond repair. If the methods proposed below do not give a positive result, then it is recommended to contact a trusted service center for diagnosis and repair.

Reasons for smartphone freezing

Not a single owner of the device faces such a problem as the Lenovo p780 phone does not turn on. When you turn it on, the screensaver just freezes, nothing happens and the smartphone does not boot. In this case, removing the battery and pressing the red “Reset” button does not help, with which you can hard reboot the device, that is, it is completely cleaned. The phone restarts and the screensaver freezes again.

In this state, the phone is called a “brick”. Most often, “bricking” occurs after the user tried to flash the kernel and gain root rights or, as it is also called, super user. Lenovo p780 does not turn on after flashing for the following reasons:

• While manipulating the phone, the user performed the actions incorrectly;
• Illiterate - crooked firmware that does not correspond to the version suitable for this model.
• Carrying out any actions when the battery is low. Before using your smartphone, be sure to carefully read the instructions. It is in it that it is written that any manipulations with a discharged battery cannot be performed.

Also, the phone can turn into a “brick” due to a technical breakdown of the processor, board or other important elements of the mobile device. A completely reasonable question arises about how to restore a Lenovo p780 brick.

Some smartphone owners decide to update the firmware themselves by reading the instructions or watching a video. They believe that with the help of such an operation the performance of the device will increase, and it will simply “fly”. But not everyone can do the firmware correctly on their own. This requires specific knowledge and skills. And if it is done incorrectly, it will turn out that the Lenovo p780 after the firmware is a brick. Therefore, experts do not advise opening the device without understanding, knowledge and skills. For this purpose, there are services staffed by professionals.

Force restart Lenovo P780 4Gb

First, let's look at several methods associated with recovery through Recovery mode. You can get into it if the gadget is charged more than 15%. At the same time, by connecting the charger, you can verify the integrity of the screen and the functionality of the USB connector.

So, if the phone responded to connecting charging and displayed the process of replenishing the battery, then after reaching the appropriate level, you can proceed to the following manipulations:

1. Press and hold the power and volume up buttons at the same time. You should hold them like this until the phone starts to vibrate. The boot screen will appear and vibration will follow, then you can release the power button. Important: sometimes the combination with the volume down button works, not the volume up button.

2. In the menu that opens, select “Reboot to system” (in some versions – “Reboot system now”).

The device should immediately reboot, followed by a normal Android boot. By the way, if the gadget does not charge, it is recommended to try other USB cables and chargers. It is possible that the problem lies precisely in them, and the phone is simply dead.

Lenovo phone does not turn on - what to do

If the user nevertheless encounters the fact that his Lenovo device simply stops turning on, then first, as mentioned earlier, he must find out the reason. There are only three classifications that are worth considering before you start working with the device.

Once the user has identified the cause, it is worth considering ways to fix the problem.

Perform a hard reset

There are two types of reboot: soft and hard. In this case, when the phone does not show any signs of life at all, it is more advisable to perform a hard reboot, because it will act comprehensively and completely.

It means that all processes stop instantly, at once. This means that some data may be lost after such a reboot. This method is also called a full reboot.

In order to accomplish this, you need a couple of actions:

1. First, take the Lenovo phone itself and start holding the power button for 30 seconds. It is located on the side of the device;
2. Now you need to wait until the logo appears on the phone. After this, the phone will reboot itself.

The difference between the method is that the user holds the power button for a long time, thereby all processes are forced to stop without having time to complete the cycle. This method is best used in rare cases when the user is really desperate and the phone does not show signs of life for a long time.

Remove the battery, flash drive and SIM card

You can try removing the battery, SIM card and flash drive from the phone, wait about an hour until all these components “rest”, and then insert them back into the phone. This method is perfect in cases where the owner of the device does not yet know what the cause of the problem is, why the phone suddenly stopped working.

In fact, the problem may lie in the fact that all these system components are “tired”. Sometimes it is really necessary to pull out each of them and then insert them back. The phone will turn on and start working as before.

Reinstall the software

The best option for reinstalling the Lenovo phone system is manual mode. It is good primarily because it is suitable for cases when the phone does not turn on. In order to successfully reinstall, you need to prepare all backup copies in advance and make sure that nothing will happen to the device in the future. After this, you can proceed with the reinstallation itself:

1. Press and hold the power and sound buttons on the phone until the “recovery” menu opens;
2. After this, a special menu will open in which you need to click on the “apply update from external sdcard” button. To select an option, click on the power supply;
3. Now you need to unzip the previously downloaded firmware file on the device and click;
4. You should wait for the program to download, and then activate the phone.

The flashing process itself does not take more than 15 minutes. Although the process looks long, it is actually quite fast. After this, you can activate the device.

Fully charge

As mentioned earlier, one of the reasons why the phone does not turn on may be that the charger has malfunctioned, that is, it is broken. The breakdown of the charger can be due to various factors, from bends and broken wires to the fact that the battery itself and the unit have become unusable.

To fix this, you need to buy a new charger and connect it to your phone. It is best to leave the phone in this state for at least 6 hours so that the battery is fully charged. It could also be that she sat down completely, which is why she showed no signs of life. If after this the device does not turn on, then the problem may actually lie elsewhere.

Restore factory settings

Restoring factory settings is a last resort option that very desperate users can also resort to. When Lenovo shows no signs of life at all, a “rollback” to the old system can save the device and make it the same as it was before. Achieving this is easy with a couple of buttons.

When the user performs a “backup” of the device, all data will be automatically erased. This means that a person will no longer be able to view the data and files that he had on his phone.

The main thing is the correct return. The best option is through the settings, but since the phone shows no signs of life, you can also use the option through the buttons:

• First, you need to hold down the Power and Volume Up keys. Afterwards a special recovery menu will appear;

• In this dialog box, you should find an item called “Erase data”. In English, this item is called “Wipe Date”. By switching through gain and decrease in volume, you can arrive at the desired option;

• After this, we confirm the actions and wait until the device reboot process completes.

After this, all data that was previously on the phone will be erased. The user will no longer be able to access them.

Use Dr.Fone program

Dr. Fone is really a program that will help the user restore the Android system. Another plus is that the program works intuitively, and it is also available for official downloads on the website.

If possible, you should take care of making a backup copy of your phone in advance, so that later you won’t have problems with all the data being lost.

To start using the program. You need to download it through the official website, and then connect the phone using a wire to the PC. Next you need to perform the usual algorithm:

1. First, launch the program and click on the Repair option in the utility menu itself. After this you can connect your phone;

2. A list will appear in which you need to select “Android”, and then click on the “Start” button. The program will begin to fix problems on its own;
3. After this, you need to make sure that the correct information and data are indicated above it. If this is the case, then click on “Next”;
4. Enter “000000”;

5. Now put the phone into DFU state by holding down the “Power” and “up” buttons. We clamp, then release;
6. Click on the “Next” button and let the program perform the firmware;

7. We wait for the end and complete the process.

After this, it is worth checking whether the device starts working as it did before. If the answer is yes, then you should rejoice, because the problem is solved.

Reset to factory settings

After the actions described above, several scenarios are possible. In addition to the usual reboot and turn on, the phone may turn off again or freeze on the screen saver. You shouldn’t be too upset about this, because the manipulations done helped ensure that a number of important functions and systems are working.

Rebooting through Recovery is an option suitable for situations in which the firmware received minor glitches that resolved themselves. If the violation in the operating system is much more serious (for example, after flashing firmware with errors), then you will have to perform a reset to factory settings. It is important to note: such actions delete all files from the device’s memory, including photos, videos and music.

1. Open Recovery as in the instructions discussed above.
2. Select the item “Wipe data/factory reset”..

The device should reboot. It can last much longer than usual (up to 10-15 minutes), after which you will have to perform the initial setup.

Moisture ingress

A very common reason that the Lenovo p780 does not turn on, and may glow red, for example, is moisture getting into the device itself. Here are the recommendations: Turn off your phone. Under no circumstances should you turn it on to avoid a short circuit. You need to remove the battery and try to dry the product.

Do not use a hair dryer for this, as hot air may cause internal parts to melt. Experts suggest using a regular household vacuum cleaner for at least 25 minutes. Just don't lean it too close to avoid damaging your device.

To eliminate residual moisture, there is another simple and affordable way - place the device in a container with rice for several hours. Rice absorbs moisture very well.

If, after all the steps taken, the phone still does not turn on after getting wet, then oxidation and contact closure have probably already occurred and only a technician can restore it.

Additional Methods

What to do if the methods described above did not help? The gadget suddenly turns off, stops responding to pressing the power button or charging - most likely the problem lies in mechanical damage. If it previously fell or fell into water, then it makes sense to contact a service center for diagnostics. Another probable reason is battery failure. The main symptom is a rapid discharge from 100 to 0 percent until a malfunction is detected. For smartphones with removable batteries, you can try to buy a similar one and simply replace it. If the body is solid, then it will not be possible to do without the intervention of craftsmen.

Battery and/or charger

What to do if Lenovo p780 turns off and won’t turn on? If your charger and charging connector are in good working order and have no mechanical damage, inspect the battery itself. It shouldn't be swollen. If everything is normal, then there is such a thing as a deep discharge of the battery. Modern phones that are in long-term use are not recommended to be completely discharged - this leads to a deep discharge of the battery and it takes a lot of time to restore their energy capacity. So plug your phone into charge and wait a few hours.

Flashing the phone

Remove the cover from the smartphone and connect it to the computer via a USB port. On the laptop, open the device manager. Let's go back to the phone. Near the SIM card slot there is a Reseat button that must be pressed.

After completing the steps on your computer, your smartphone will appear in the device manager. Click on it and update the drivers (they can be downloaded or updated via the Internet).

If you have completed everything, then you can move on to the next step. Now you need to disconnect the phone from the computer and run the Flash Tool program.

To fix the problem that prevents your Lenovo P780 from turning on, you need to flash the device. First, in the program, click on the Scatter loading button. In the window that opens, select the location where the firmware is located. Click on the file and the utility opens it. All files must have a check mark. Check the box where it says DA DL All With Check Sum and click on the Upgrade button.

In a few minutes the program will prepare for firmware. We take the phone and connect it to the computer. When the device is identified, the firmware will be installed. After 10 minutes, the green circle should light up, indicating the successful completion of the process.

Turn off the phone and start it. If everything went well, the smartphone will boot and you can reinstall all applications.

Hardware problem

Nothing lasts forever, including technology, no matter how modern it is. If your Lenovo p780 does not turn on, or the Lenovo p780 does not turn on and the red indicator is on, and all of the above is after basic diagnostics and comparison of facts (there was no flooding, there was no fall either) - then the problem is in the hardware of your product, and here it is possible both memory and power controller, processor, and other components. Contact an authorized service center for high-quality replacement of spare parts.

Lenovo is a Chinese popular company. Although its equipment is manufactured in China, Lenovo is one of the few companies that produces truly high-quality products. Many products can be found much cheaper than competitors, while they are of better quality. Of course, not everything is so smooth for this company either. Some smartphones, computers, and laptops have shortcomings that become apparent during long-term use.

Now we will look at the rather popular Lenovo P780 device. For many users, after a year of use, the phone begins to perform worse. How does this manifest itself? When loading, the Lenovo P780 does not turn on or simply hangs at boot. Of course, this is not the only problem that users face. For example, due to carelessness, the phone is filled with water. What to do in this case? Let's figure it out.
