Disassembly/Repair of the mobile device ZTE Blade V50 Design (ZTE Blade V50 Design ZTE 8050) with each step description and the required set of tools.

⚠️ Before disassembling, do not forget to turn your phone off.

First of all, we need to remove the SIM card tray.

For this, we’ll use a special eject tool.

Insert it into the hole and carefully push the tray out.

If the tray doesn’t come out smoothly, we can also use tweezers to help pull it out.

Next, we need to heat the back cover to about 70 degrees Celsius or 160 degrees Fahrenheit. For this, we’ll use a heating pad, but you can also use a heat gun or hairdryer.

Take note: on this model, the back cover is additionally glued down in the camera area. That means we also need to heat that section to make separation easier.

Now let’s move on to removing the back cover. For this, we use a thin plastic film, sliding it into the gap between the back cover and the midframe, and carefully working our way around the edge to slice through the adhesive.

Go slowly along the edge—don’t push the film too deep under the cover, since we don’t know exactly what components may be underneath.

After going all the way around, we’ll try to peel the back cover off near the camera section. Using the thin plastic film, carefully loosen the adhesive in this spot.

The cover here is glued down very firmly, so extra caution is needed.

Next, we need to remove the screws.

For this, we’ll use a 1.5 mm Phillips screwdriver or a Phillips #000. These screws secure the midframe.

Unscrew them carefully and place them on a dedicated surface in an organized layout, since the screws may vary in size.

First, we unscrew the two screws at the bottom.

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew the three black screws at the top.

Now we move on to removing the midframe.

We start with a thin plastic film, unclipping a few catches near the SIM tray slot, then switch to a sturdier tool.

On this model, the midframe is also held in place pretty tightly, so we need to be careful. Don’t force it, otherwise we could damage the edge of the display.

In our case, the fingerprint sensor just falls out—it’s not secured to the midframe.

At this point, it’s best to cover the camera lenses. For this, we use a protective film.

Note that we stick the film onto the rim around the lenses, not directly on the glass.

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew the five short screws.

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew the one silver screw.

Next, using a non-metal tool, we need to remove the cover.

Carefully pry it up at the edge, unclip the catches, and lift off the cover that protects the motherboard.

It may have a little adhesive at the top. Set it aside.

Then, using a non-metal tool, disconnect the battery connector.

ℹ️ The ZTE Blade V50 Design ZTE 8050 model has a battery E6553ZTE-B with a capacity of 5000 mAh (also known as a rechargeable battery).

And we can also disconnect the fingerprint sensor flex.

Unplug the connector and gently peel off the flex cable, which is attached to the motherboard shield.

Now we can move down to the lower section.

Here too, we need to unscrew the six black screws.

These may also differ from the previous ones, so keep them organized separately.

We use the same 1.5 mm Phillips or #000 screwdriver.

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew the two silver screws.

After unscrewing, we can remove the cover—this one likely includes the loudspeaker.

Find a spot to pry under, lift it up, and detach the cover. Indeed, when we flip it over, we see the speaker mounted inside.

Next, disconnect the coaxial cable connector, free the cable, and then disconnect the inter-board flex connector.

Now we can remove the sub-board.

As always, carefully pry it up, lift it, and take it out.

On the sub-board, we have the charging port, microphone, and headphone jack. 

Now we can remove the cameras.

As we can see, they are bonded together with a heat-dissipating foil. Handle them with care.

The main rear camera is also slightly glued to the display frame.

So, carefully detach the rear cameras—remember, they’re connected by that thermal foil. Don’t pull hard on the flex cables to avoid tearing them. Set the cameras aside.

We can also remove the front camera. Again, peel back the thermal foil—it will be useful during reassembly.

And we disconnect the coaxial cable connector, then the inter-board flex, then the display flex connector.

Peel back the thermal foil—it’ll also be reused during reassembly.

After that, check for another screw securing the motherboard. For this, we use the same 1.5 mm Phillips or #000 screwdriver.

Now nothing’s in the way. Carefully pry up the board at the right spot and lift it out.

⚠️ Do not bend the circuit board when removing it or push tools under it. Unbeknownst to yourself, you can damage components or cables from the inside.

ℹ️ In the display frame remained: the earpiece speaker, battery, and vibration motor.
