CPU command by reading the contents of the phone to work , which requires software content must be correct , can not have the slightest error , software failures encountered in accordance with the following method for processing.ps7service manual download site
First, the narrow range
First need to determine fault narrow failure and to determine the type of fault that belongs to a hardware failure ( such as memory itself is damaged ) or internal software failure. If a hardware failure, to ensure the absence of the poor welding , and should be replaced. Or software failure , you must use software maintenance to re- write the software ; maintenance practices found that the vast majority of mobile phone software failures in chips , and most of the data is missing or wrong chip .
Second, treatment failure
Mobile software failure occurs , there are two ways to disassemble free disassemble and processed , the following describes the characteristics of two ways . Free way to disassemble the aid of specialized software maintenance equipment , with computers, in the case of mobile phones are not disassemble processing software failures , such as the current full-featured digital good hand , software fault repair instrument (BOX king ) , may processing such as locks , displays " Contact service Provider ", " bad phone , please repair ", " security code ", " bad software ", " does not know the card ", " no network ", " black" , "Low power alarm "faults disassemble deal with free software faults very convenient, do not disassemble , do not change the phone's IMEI IMEI, the phone's internal circuitry is also little affected.
Free disassemble treatment is not a panacea , if the phone can not boot or run into some other no free disassemble handler branded phones ; encountered only the phone's software failure or a character with a chip blowing hot air gun , with universal programmer ( eg LABTOOL-48), with a rewrite computer ( PC beforehand that there should be a variety of mobile phone data ) , which uses the computer 's normal data covering existing data failures phone , if not failure phone data of the same model , only its own expansion , the need to go first to one of the same model phone to remove the chip , which reads data programmer , deposited into your computer.
