BlackBerry always turns on and off First Aid 50

First of all, I don't know how much money you bought, there are a lot of refurbished machines for BlackBerry at the moment, basically marking 7230 7290 8700 These models are widely popular with domestic players, and there are even some stores that can be sold at a low price of 300-500 yuan, the so-called fourteen-day machine, (the new machine has a faint sandalwood fragrance when the lid is opened, if it is a refurbished machine, it is generally necessary to beautify the fuselage, although the appearance is smooth but not dry enough, there is a rubber smell after opening the cover or removing the battery, plastic smell, or the smell of chemicals); If it is such a machine, then it is guaranteed to be a refurbished machine, such a machine, it is very easy to have problems, there are many problems, and the information provided by the landlord is not detailed enough, not very good.

1. From the situation of the landlord, it is generally believed that it is a virus in the smart phone, but at the moment BlackBerry's mobile phone does not have any decent virus, (Berry smartphone runs the Blackberry operating system, BlackBerry takes into account security factors, so it is only a semi-open system) basically does not pose any danger in this regard, common viruses are: the mobile phone screen continues to flicker: (lights virus), the screen shows sensational words or terrible icons:

ghost virus), continuous beeping sound: (falsealarm virus), small planes flying around on the screen: (sprite virus), pretending to be **malicious program:

Alone virus) and so on. But these are basically not harmful to BlackBerry, so I will rule them out for the time being.

2. If there is no virus, it is not a problem with the machine, it is a conflict of software, the landlord can try to try it himself, uninstall some soft armor to try, in fact, the most powerful BlackBerry is email, but this point seems to be of little use in our China.

3. The most troublesome thing is also the last point, that is, the quality problem of the machine, the hardware, if there is a warranty, send it for repair, don't disassemble the machine yourself, there is a problem with the line, and the gain outweighs the loss.

To give you a**:

There are two reasons, one is the quality of the phone itself.

But since you are asking the question, then we will rule it out. But I thought it was a problem with the software, and you didn't use your phone to download anything. Connected to your computer?

My friend has a mobile phone that is poisoned.,I can't even turn it on.。。 It's good to use the computer to disinfect it、So mind if you kill the virus first.,If you can't solve the problem.,Only send it for repair.。

If there is a problem, I suspect that yours is a parallel import or something, take it to repair it, check it,

If your blackberry is not a regular smuggler, then please find a seller as soon as possible. Basically, they are all refurbished machines.

Generally, there are several possibilities for the mobile phone to automatically shut down:

1) The protection circuit in the lithium battery is too sensitive, so the current will be powered off as soon as it is large.

2) The battery itself is aged.

3) There is dirt on the metal sheet at the contact point of the battery, which causes poor contact with the power supply.

4) The joint between the battery and the mobile phone is easy to loosen.

If the first two problems are found after inspection, then they must be sent to a special repair shop for repair; If the latter two problems are caused by the oxidation of the dirty metal sheet of the battery, the situation will be improved as long as it is wiped clean with a glue stick. Putting paper or film between the battery and the phone can also solve the problem of poor contact caused by loose batteries.

If there is a strong magnetic field around your work environment, the phone will automatically shut down. There are also times when the keypad without a lock squeezes into it and shuts down. If the battery is not tight, sometimes it will be powered off (if the battery is not tight, it will be very slow when it is turned on, and if it is the other two cases, the speed of rebooting from the new is very fast.) ）

1. Please confirm whether the power button has been touched by mistake. Press and hold the power button for more than 10 seconds, and the phone will shut down and restart.

2. Keep your phone fully charged. The battery will automatically shut down when it is low to a certain extent.

3. Check whether the timer switch function is turned on.

4. The electronic components of the mobile phone motherboard fail, resulting in the power supply not being on the line, which will cause the mobile phone to shut down automatically.

First of all, check whether there is an automatic power on and off time (mainly whether it is the same time to shut down for no reason...) If you don't have the settings, I think you can just flash the rom, if there is a problem with the software, updating the rom should solve it. If the ROM is updated on a daily basis, go to the repair point to do a hardware test.

Just brush the system yourself BlackBerry's flashing is very simple It's a little longer You can let me send you the tutorial BlackBerry's flashing tutorial is basically universal.

Take a look at the option Auto Power On Shutdown Whether the shutdown is set by mistake, if not, there are two problems that can lead to shutdown, the system has a problem, which needs to flash or erase the device to restore the factory settings, and the other is that the battery is loose, or the battery is internal faulty.

Solution: 1. Check whether the mobile phone card is installed correctly, sometimes the installation is not normal, it will also lead to automatic shutdown 2. Whether the memory card is installed correctly.

3. Whether the metal removed from the mobile phone and the battery is loose or damaged 4. The battery problem needs to be replaced by the manufacturer.

5. Software problems, whether there is any incompatible software installed recently that causes automatic shutdown 6. Hardware problems, this needs to be detected by the manufacturer to determine the problem.

The battery is aging, try it again!
