Flashing is a system upgrade or replacement of a third-party system on the device, which will not affect the hardware of the phone.
However, the flasher will erase all personal data of the device (it will not affect the memory card data), so it is recommended to back up the relevant data before flashing.
There are mainly the following reasons why flashing your phone may cause damage to your phone:
1.The camera cannot be connected after flashing, the touch screen is not sensitive, and the handset is invalid.
This situation is not the damage of the hardware, but the imperfection of the third-party system itself, resulting in the inability to call the hardware facilities of the mobile phone normally. At this time, you only need to choose another ROM that is more stable and complete. Comparatively speaking, the stability of the official system is higher than that of the third party, because it is recommended to use the official system.
2.There is no signal after flashing, the signal is poor, and the wifi cannot be used.
This situation is also not hardware damage, some mobile phones need to be flashed before the corresponding baseband or other situations can be brushed, such as Samsung needs to back up IMEI before flashing, etc. In this case, the user only needs to refer to the corresponding tutorial according to the specific situation.
3.The font library is corrupted.
This is now found that the most flashing to the mobile phone caused substantial damage, this situation is because of improper flashing operation, etc., resulting in the mobile phone font damage resulting in the mobile phone can not be turned on, font damage can only be repaired by professional maintenance personnel.
4.The phone gets bricked.
For flashing, the probability of occurrence actually depends on the operation. Before flashing, you should carefully and strictly follow the flashing instructions or tutorials, and at the same time, you should break down the relevant content of the model, such as preconditions, before flashing, so as to flash the machine on the basis of certain basic knowledge.
Many users may just be stuck on the first screen or other situations after flashing, etc., at this time, there is no need to be nervous, the mobile phone may just be a system failure, which is commonly known as the quiet car "half a brick" and "fake brick". Please refer to the corresponding tutorial of the corresponding model to save the bricks.
If the mobile phone cannot be turned on, the computer cannot be recognized by the computer, and the charging cannot be charged, the mobile phone may become a real brick, and you can only turn to professional maintenance personnel for help.
