Seven reload software

    Phone control software is quite complex , likely to cause data errors , part of the program or data loss phenomenon that we call software failure , therefore , re- load the software on the phone is a mobile phone repair process, a common and effective method . To repair software failures require special equipment .

    In front of the related content , has introduced a software maintenance more frequently used two instruments : LABTOOL-48 universal programmer and free disassemble software maintenance , relatively speaking , BOX king free disassemble software maintenance is a very good software repair equipment , fully functional, easy to use, can basically meet the needs of the general maintenance of the equipment is not only for some special software failures for repair , but the fault programs, data for a comprehensive treatment program that , re- write the correct data chip content , no matter what kind of phone software failure occurs can be fully restored , especially the many phone's data , the program has a version of the distinction should be used in conjunction. LT-48 software maintenance is also a good choice, the correct data it can store various versions , the new version can also be encountered continuously added into the computer , of course , the disadvantage of this device is also obvious software fixes , such as expensive to disassemble and repair and font handling for some new BGA need expensive special adapter seat, coupled with the current mobile phone chips and a lot of character have been combined, this universal programmer has been powerless.

Eight cross- connection

    Cross- connection of a mobile phone repair is an emergency method , especially the more serious corrosion , it is necessary when using this method artificially circuit breaker phone , available high-strength thin wire maintenance (φ0.1) 0Ω resistor or a jumper one unit , in addition, when the phone is not network fault repair , can also be a 100pF capacitor connected across the input and output filters for emergency repairs and judgment. Note that the wire must not be used when the circuit is connected across the across the ends of the microstrip line , otherwise, would cause unexpected failure.
