Caused by software failure is strange, but summed up in four main areas: software, disorder, damage to the cell phone's screen Depot Repair and other information, which mainly are: display "contact service provider (CONTACT SERVICE)" ; display "Cell phone is invalid, contact the service provider (CELL PHONE FAILED SERVICE)"; Display "software error (WRONG SOFTWARE)"; "Please Wait enter the eight special code (Please Wait To Enter Special Code)". The instruction of  cell phone  jammer contains the classification information of cell phone  jammer.
Display "Illegal software downloads (illegal software loaded)" user-machine but can not unlock the lock, all the original passwords are not changed, the factory unlock password is invalid, this is the software failure. Circuit under normal circumstances, that there is no power, no network, will screen crashes, no signal, low power alarm, no launch failures, also belong to the scope of software failure. In the cell phone's fault, some fault is very obvious that the problem is caused by software, such as the cell phone is locked, etc., just processing software OK. Sometimes you can judge by the current turn, to cell phone does not boot, we generally observe the power to largely determine the current, such as the 8088 Power of 30mA or so scheduled for a return to zero. The catalog of mobile phone jammer   needs to be revised.
For fixed-screen crashes, for example Amoi A8 big screen does not display, small screen is also scheduled to screen software failure; for software failure to boot, we generally first view of its current version number, such as Samsung, Siemens, TCL cell phones, because the old versions of programs exist to teach many hidden faults, generally use the updated version of the upgrade. Also note that the corresponding version of the problem, such as TCL have a different display of the corresponding version number, Bird S1000 outlet "bad software" (bad software) This failure does not cause more than the software version, as long as the software version can write solve the problem. The quality level of   cell phone jammer  has the specific stipulation.
In addition, S1000, old and new LCD module and a combination of old and new version of the software to choose the right, otherwise there will be "bad software" fault. For example: Old LCD + old modules for software 409AM11B. 19A, if wrongly used the 412KM12A. 21A or 412KM12A. 20F will appear "bad software". Old module for software 412KM12A.21A, if misuse of 409AM11B.19A or 409AM11B.19F. Will appear "bad software" and so on. Samsung also have different versions of the machine corresponds to the upgrade process. Of course, there are repairs out of the software failure, which is due to the program for hardware manufacturers to track the work of the code, resulting in replacement of the corresponding components appear after software failure can not be used normally. Different powers of  Cellular Phone Jammer  can meet different requirements.
NOKIA cell phones from DCT3 For example, have been hardware encryption of code; such as V208 Samsung said the machine is now also used for code technology hardware, software maintenance for bringing us obstruction. CPU internal command by reading the cell phone to work, which requires software content must be correct, not the slightest error, software failure encountered what methods should be handled. The director will perform the determination of shielding radius of  cell phone  jammer.
