In the 21st century, human life is closely connected with various digital technologies. Even a child can hardly imagine his life without various gadgets.

Many people, for one reason or another, do not want to contact service centers for the help of professional craftsmen.

Of course, you can repair equipment at home. But not everyone knows how to disassemble a tablet, mobile phone or even a mouse with their own hands. We will deal with the breakdowns of the “tablets”, and find out how to open and repair it.

Reset to factory settings (hard reset) for Lenovo A850i phone

There are many reasons why you may need to perform a hard reset on your Lenovo A850i smartphone. Typically, this procedure is performed to restore the functionality of a system that has been damaged by viruses, deletion of system files, clumsy firmware updates, and many other things. It is very easy to perform a Hard Reset on any smartphone, but you should be aware of the consequences of this action and be able to make a backup copy of the system and files. We will talk about all this in detail below.

Disassembly tool

If you want to seriously and permanently engage in tablet repair, then it is best to buy a basic set of elements, which must include:

• Blades of various shapes;
• Positive and negative screwdriver;
• Torx screwdrivers;
• Triangular blades.

In principle, if you just want to try, then all this can be replaced with a couple of unnecessary bank cards and a pick, however, you will still have to purchase screwdrivers. Since manufacturers prefer to use screws with non-standard heads, for example, a polygonal star.

Analysis of the algorithm

In the most general case, we simply find a place where we can insert a plastic card. Usually this place is located near the volume buttons. We need to carefully, prying up the edge, detach the front and back parts of the tablet, releasing the fastenings. Sometimes you can use a pick instead of a card.

With this method of opening the case, nothing will be damaged; feel free to move the card along the case and the latches will open

But you need to be very careful - in many models, especially those made in China, manufacturers love to hide the bolt fasteners. Before starting work, be sure to make sure that there are none. Moderate force should be used. If the latch does not budge, check additionally to see if there are any fasteners in this place. Sometimes they can be disguised as stickers or under places that imitate part of the touchpad.

It doesn’t matter which manufacturer your tablet is from - Asus, Samsung, Lenovo or Prestigio - in all cases the algorithm of actions will be the same.

After you have managed to walk around the entire perimeter, do not rush to pull off the lid. First, make sure that there are no cables going to it; if there are, disconnect them if necessary.

The tablet is open, and we can begin the work we need - replacing the battery or any other parts, cleaning the device from dust.

How to open the tablet

First of all, when disassembling the tablet, the back cover is removed. After this, the main parts will appear in front of you: board, battery, etc. Now we will tell you how to properly dismantle the back cover.

Removing the cover

Many tablets have slots on the side for SIM cards and a flash drive. They are closed with special caps; they should be disconnected first. This is done to make it easier for us to remove the cover.

Next, you should unscrew all the screws located along the edges that secure the cover. Be sure to check the slots for flash drives and SIM cards . Often additional fixing screws are located in these places.

Important! We recommend placing the screws for attaching the lid into a plastic bottle cap. When you unscrew the tablet board, these screws need to be placed in another cover.

This is done so as not to confuse them. Because if you tighten other screws, you can damage the threads.

Removing the cover

Next, using a plastic spatula or card, you need to pry off the latches of the rear wall. To do this, place the tablet with the screen facing you. Then carefully insert the spatula into the gap between the body and the cover . You need to insert the scapula until you hear a characteristic click.

Then you need to slowly move the spatula along the body so that all the latches come unfastened . When removing the cover, make sure that there are no wires or cables holding it in place. If there are cables, then you need to use a spatula to pry the latch up . After this, you can remove the cable and put the cover aside.

Opening the lid

Opening the back cover of any tablet is not very easy, so let’s try to understand the basic stages of work. If you are the owner of a rare model, it is better to read the relevant recommendations on specialized forums or seek help from a specialist.

To work you will need:

• a set of screwdrivers including straight, Phillips, triangular and hexagonal;
• guitar pick or plastic card;
• hot air gun

Progress

1. First of all, take a good look at the tablet. Before removing the back cover, on many models you need to unscrew the screws or snap off the latches. You will most likely notice the fasteners, but the screws may be hidden under rubber plugs. If you see these, carefully pick them up and check if there are any screws underneath them.
2. Screws found. Select a suitable screwdriver from your set and unscrew them. If there are latches, unclip them.
3. Now the very painstaking work begins. Slowly pry the lid of the tablet with a pick or plastic card. This must be done with extreme caution so as not to damage fragile components of the equipment. In most cases, the work of removing the back panel ends here. But there are also models that are difficult to open.

Preliminary preparation

Before starting work, you must turn off the tablet and remove all SIM cards and USB drives from it. If this is not done, the cover may not come off or even break the cards or mounts. Pay attention to cleanliness - we will get inside the device and we don’t need excess dust, much less dirt, there.

Reset to factory settings via buttons

Now we reset Lenovo to factory settings in a different way. We will use physical buttons. This method of returning to the original system data is especially relevant if the BIOS is infected with a virus and you cannot even turn on the gadget. This reset Lenovo is done as follows:

1. Press and hold the volume button and the power button at the same time. We hold them for about 10 seconds.
2. After this time, you will see the Android logo on the screen. This means that the buttons can be released.
3. After a while, Recovery will open, and using the volume down and up buttons, select the item we need - Wipe Data. This will allow you to do a Hard Reset of all settings.
4. The BIOS will again ask if you are sure that all data has been deleted. We agree, pressing the volume up button and restoring the system.
5. After rebooting and setting the settings, the phone works like new.

Reset to factory settings (hard reset) for Lenovo A850+ phone

There are many reasons why you may need to perform a hard reset on your Lenovo A850+ smartphone. Typically, this procedure is performed to restore the functionality of a system that has been damaged by viruses, deletion of system files, clumsy firmware updates, and many other things.

Difficulty removing the cover

Devices that are difficult to open include Apple products. Tablets of this type are very difficult to disassemble, so think carefully before doing this. For some models, for additional fixation and protection from non-service maintenance, the back panel is glued on. This is where a hot air gun comes in handy:

1. Turn it on and blow on the joints of the tablet.
2. We try to remove the back cover, hooking it with picks.
3. If the lid does not come off well, then as the work progresses, every 3-4 cm we leave a pick between the back wall and the screen. The main thing to remember is that you should work slowly and carefully. Then everything will work out.

A tablet is a device assembled in such a way as to create the impression of being monolithic. There are no screws or latches, no places where the two halves of the case fit together - none of this is practically visible. This is a rather misleading idea, since the equipment can be disassembled if necessary. Specialists cope with this procedure quite quickly, all that remains for the owners to find out is the act of opening the lid of the tablet.

When to do a Hard Reset on Lenovo

The need to return all factory settings of the phone arises in the following cases:

1. The device started to work slowly.
2. When loading certain applications (or any), the system freezes seriously.
3. The phone is infected with a virus.

There are two main ways to reset Lenovo. The first of them involves working in the phone menu, and the second involves using physical buttons. We will talk in more detail about how to do a hard reset using each of them.
