Coolpad S mobile phone can t turn on when water is in the water, what s the solution?

Water ingress and crashing are the two major taboos in the use of mobile phones, and water ingress of mobile phones is particularly serious. According to an engineer from Guoxin, after the mobile phone gets into the water, the first thing to do is to turn off the power, of course, not to press the shutdown button, but to remove the battery. Because as soon as you press the shutdown button, the mobile phone will be powered on, and it is likely that a short circuit will occur, causing damage to the mobile phone, and then send it for repair as soon as possible.

If your phone's warranty has expired and you don't want to send it for repair, you can boldly take it apart! Wipe the parts of the phone with a tissue, and then blow it with a hair dryer for a few minutes, in order to ensure that all the internal parts are dry, it is advisable to air dry the phone for a few more days before you can turn it on again.

2. Once the mobile phone is flooded, the battery should be removed immediately, and the mobile phone must not be turned on immediately to understand the condition of the mobile phone. After removing the battery, do not use a hair dryer to deal with it, and immediately send it to the repair professional to disassemble the machine for water treatment, such as falling into sewage or corrosive liquid, and use ultrasonic cleaning and drying before proceeding to the next step of maintenance. If the mobile phone can still be used after water penetration, it should be sent to a professional to deal with it to avoid corrosion of the circuit board and make it impossible to repair.

No matter what kind of water the phone falls into, you should first remove the phone battery and no longer power the phone. If it falls into clean water, remove the battery and clean the phone with anhydrous alcohol, because the alcohol volatilizes quickly, and the water on the circuit board can be volatilized together. Then use a heat gun or hair dryer to dry the circuit board, and then power up the test machine, and most mobile phones will work normally.

If it falls into the sewage, it should be cleaned immediately, and the dirt that can be seen should be cleaned first. Use a brush to brush off the impurities attached to the pins of the components. Then, the circuit board is scrubbed with an alcohol cotton ball, and if the pollution is serious, the impurities must be vibrated out with the help of an ultrasonic washing instrument.

Then use an air gun to dry the circuit board, and then repair all the chips.

If the mobile phone accidentally gets into the water, you can try the following ways to deal with the mobile phone urgently to avoid secondary injury:

1. Please take the mobile phone to a dry and ventilated place as soon as possible, and use a dry paper towel or towel to blot the water stains on the surface of the mobile phone.

2. If the phone is turned on, press the power button to turn it off; If your phone is turned off, don't try to turn it on.

3. Please remove the SIM card and microSD card as soon as possible.

4. Please bring your mobile phone to the after-sales department of the mobile phone brand for testing and processing as soon as possible to avoid unnecessary losses.

2. Please do not bake with a hair dryer or stove after water ingress, so as to avoid liquid flowing into the inside of the mobile phone and damaging the mobile phone at high temperatures.

3. Some mobile phones can be turned on and used normally after simple treatment, but the mobile phone is composed of precision electronic components, and there is a hidden risk after water ingress, so it is recommended not to try to turn it on.

4. During the after-sales maintenance process, the data may be lost, it is recommended to ask the staff how to back up the data.

Don't worry, landlord, and look at what the upstairs says, "fastboot: shutdown status, volume +, and then plug in the data cable".

Meaning,Turn off the phone (since the screen is not lit,Or ignore it),Open the back cover and dial the battery,After a minute, then install the battery,Then press and hold the "volume +" with your hand,Connect the data cable to the brain,If the screen is lit,There is a red and some English in the middle,Then congratulations on not becoming bricked! Then go to the official website of Coolpad**"Yulong General**platform ygdp or the official flash package to re-flash it. Of course, the official website is slow, you can find a disk to share on this forum, so that it will be much faster.

Fastboot doesn't work, so I have to send it to customers.

Hello! Welcome to the Coolpad Enterprise Platform.

Have a great day!

Sun-drying, as long as the screen is not too serious, if the screen is seriously waterlogged, it will not be good.

There are many reasons why you can't turn on the machine, you need to check them one by one, you can charge it for half an hour first, try to see if it can be turned on, if it can't be turned on, it may be a hardware or software problem, and you need to take it to a repair shop to test.

Hello, first of all, don't worry, the phone is in the water, if it is clean water, it is easy to do, save yourself first, not clean water, take it directly to the mobile phone store to deal with the self-help method, first remove the battery, card, can be dismantled, the mobile phone case is also dismantled, dismantle the mobile phone with a hair dryer, and then the sun comes out to dry, do not dry when the sun is strong, it is easy to expose the screen, blow the wind with resistance! Two shirts round day or a day after the boot to try, if there is a white screen, flower crack closed screen, black screen, can not be turned on and other hardware failures, can only be sent for repair, if the keyboard is not working, and press the health disorder, but also need to blow and dry. In fact, the mobile phone is not so easy to break when it gets into water, which is the best self-repair method.

It is highly recommended to deal with it briefly first and repair it at the mobile phone store.

After the mobile phone is flooded, most of the cases cause failures such as failure to turn on, abnormal display of the mobile phone and noise on the call. And the source collapses, some water inlet machines corrode the circuit board more seriously, resulting in the mobile phone can not be repaired for life. Therefore, when the mobile phone enters the water, whether it falls into clean water or dirty water, the mobile phone battery should be removed, and the mobile phone should not be charged again, such as continuing to charge the mobile phone, the internal components of the mobile phone will be short-circuited and burned out.

This will further expand the fault and make it more difficult to repair, so do not charge the phone again and remove the battery after encountering water intrusion into the phone. Then check whether your phone has been dropped into clean water or dirty water. If you fall into clean water, as long as you stop the mobile phone immediately, the fault will not be expanded.

After removing the battery of the mobile phone that fell into clean water, wash the mobile phone with anhydrous alcohol. Because alcohol evaporates quickly, the moisture on the circuit board can be volatilized and taken away. Then use a heat gun and hair dryer to dry the circuit board, and then you can charge the test machine, and most mobile phones will work normally.

If the mobile phone fell into the sewage, the first thing to do is to disassemble the phone to see the degree of corrosion of the mobile phone circuit board. Because there are many acid and alkali compounds in sewage, they will cause different degrees of corrosion to mobile phones. Therefore, after the mobile phone falls into the sewage, it should be cleaned quickly, and the corrosive materials that can be seen should be cleaned first.

Use a brush to brush off the impurities attached to the pins of the components. Then, use an alcohol cotton ball to clean the circuit board.

Hope it works for you

It's okay to use a hair dryer, but don't blow it too hot, otherwise it will burn out, and if you have patience, put it on the balcony to dry.

Just use a hair dryer to blow the handle, it's very useful.

If you don't turn it on, blow it with a hair dryer!

1. First of all, disassemble the whole machine, and prepare to use the corresponding screwdriver before that.

2. When removing the screen, pay attention to gently separating the chiplet connected to the motherboard from the motherboard.

3. Before removing the metal shielding isolation layer, tear off the network access card and the card slot sticker under the network access card.

4. The last is to take a hair dryer to dry blow, but don't blow on the screen for a long time, such a high temperature will destroy the screen, even if the screen has a watermark, you can use the phone normally, the water in the screen will generally dry in two days, and you will see that the watermark inside is getting smaller and smaller.

5. Blow the front and back of the motherboard to ensure that there is no moisture residue, and try to blow out the water at the earpiece and buttons.

6. Finally, put the disassembled mobile phone in a dry and noisy place, preferably about two days, and then install it.

When the device is fully charged, after backing up data, press and hold the [Power Button] and [Volume +] buttons for 10 seconds with the device off (off).

After entering recovery mode, move the cursor with [Volume+], Volume-] (see figure below).

Operate 2-wipes again

Select Wipe Data Factory Reset > yes, home] to confirm.

Select wipe cache partition > yes , home] to confirm.

Select reboot system now > yes , home] to confirm.

After doing this, restart and the repair is complete.

Hope this helps you!!

When you take out the battery and turn it on every few minutes, you may sometimes see that the app is being optimized.

Turn off the phone first, then press and hold the power button and the volume 10 button at the same time to enter the recoveryr mode, the power button confirms the cursor, the volume button selects the cursor address, selects --wipe cache partition to clear the cache partition, selects --wipe data factory reset to clear the data partition and restore the factory settings, and finally selects the line with rboot to confirm the restart.

1: No matter what kind of water the phone falls into, you should directly remove the phone battery (instead of pressing the power off button) as soon as possible!

2: Use undusted napkins, cotton balls, cotton swabs, etc. to absorb all the water that can be wiped off outside.

3: If it falls into clean water, you can clean the phone with anhydrous alcohol, because the alcohol volatilizes quickly, and the water on the circuit board can be volatilized together (provided that you have anhydrous alcohol). If it falls into the sewage, it should be cleaned immediately, and the visible dirt should be cleaned first, and the impurities attached to the components should be brushed off with a brush.

4: Use a hair dryer to swing the dryer from a distance. (Be careful not to blow too close or to one place for a long time).

5: Keep the phone in a cool and dry place for 24 hours, if there is no hair dryer to dry the water, it is best to leave it for 48 hours.

6: Install a battery with sufficient power to test it, if it can't be turned on, then you have to take it for maintenance.
