This post take a look at the security code problems of mobile cell phones and how to fix/correct them.

TYPES OF SECURITY CODEES

The following security codes are not uncommon with mobile cell phones.

MANUFACTURERS' DEFAULT SECURITY CODES

These are security codes placed in Cell phones by manufacturers to prevent usage by unauthorized persons. For example,

-Nokia cell phones default security code is 1,2,3,4,5

-Motorola cell phones default security code is 1,2,3,4

-Ken xin da cell phones default security code is 1,1,2,2

USER PLACED SECURITY CODES

You are advised to change the default security codes.When this is done you have a user placed security codes.

SUBSCRIBER IDENTIFICATION MODULE (SIM) SECURITY CODES.

Both the PIN and the PUK codes are network features of the Subscriber Identification Module (SIM) Cards that serve as protection for unauthorized usage of the SIM cards. They have default values placed by the various network.

FIX FOR SECURITY CODES PROBLEMS

Both the default and self/user placed security codes can be fixed by a fast unlocking software.

FIX FOR MOBILE CELL PHONE SCREEN PROBLEMS/DISEASES

In order to fix the screen problems of mobile cell phones;

(1)Check for physical damages on the screen. Common observations include' ink 'spillage ,Crackek or broken screen,the Flex etc.The fix for these cell phone screen problems is outright replacement of the screen with a good one.

(2If the above fail to correct/fix the screen problem,resolder all components on the PCB using a rework station. This is to make sure all components make contact with the PCB.

(3) Next wash/clean the entire PCB and components with brush and a volatile liquid. Most cell phones' screen problems including Nokia,Motorola,Samsung,Sagem,LG,Verizone and ATT phones,etc are fixed this way.

(4) On rare occassions,the above may not fix the screen problem and Flashing with a suitable flash file may be called for.

In order to fix the charging problems of the mobile cell phones including those of NOKIA,sagem,Samsung,LG,Motorola,Verizone and ATT cell phones,

(1)Try to charge the cell phone with another working charger.If this charger charges the phone it means that it is your charger and not the phone charging system that is bad.You only need to replace your charger to clear this cell phone charging problem.

(2)If the above does not clear the mobile cell phone charging problem refered to as phone disease by some people,then clean/wash the charging pot with the ais of a brush and a volatile liquid sush as methylated spirit.This step should however be after you had resoldered all the charging pot ic to the PCB with a rework station. (You must not clean/wash first as you could uproot not too rooted ics from the PCB.) Most charging problems of cell phones are fixed in this way.

(3)If you are still not able to solve the mobile cell phones' charging problem with the above ,then you can always make use of a Desktop charger to charge you cell phone.

MOBILE CELL PHONES PROBLEMS:FIX FOR RINGER PROBLEMS FOR NOKIA,MOTOROLA,SAMSUNG,LG,NEC,SAGEM,IPHONES,SONNY ERICKSON ETC

In order to fix the ringer problems of mobile cell phones for Nokia,Motorola,Samsung,Sagem,NEC,LG,Iphones,Black Berries etc the procedure is described as follows.
Go to the settings menu and make sure that the ringer option is turned on. Experience has shown that most people who complain of mobile cell phones ringer problems have the ringer option turned off in the settings.
If this does not fix the cell phone's ringer problems then check the ringer with a multimeter to ensure that the ringer is  functional and not damaged. If the ringer is damaged, the cell phone ringer problem can be fixed by replacing the ringer with a new one.If the ringer is in order but does not ring when activated then there is the need to check the ringer track on the PCB to ensure continuity. Discontinuity in ringer track can be fixed by using a tiny copper wire to join the ends in question. This may fix the cell phone problem.
These method work for Nokia cell phone ringer problems,Samsung cell phones ringer problems, Sagem cell phones ringer problems,NEC,LG.Iphones,etc.
Before joining the necessary ends with a tiny copper wire make sure you heat the entire PCB with a rework station to ensure that all ic and components are fixed to the ground

MOBILE CELL PHONE PROBLEMS: FIX FOR MOUTH PIECE PROBLEMS IN NOKIA,MOTOROLA,SAMSUNG,NEC,LG,SAGEM, SONNY ERICKSON,IPHONES,BLACK BERRIES ETC

In order to fix the mobile cell phones problems in such cell phones as Nokia,Motorola,Samsung,Sagem,NEC,LG,Sagem,Iphones,Black Berries and others the procedure below could be followed.

MOBILE CELL PHONE PROBLEMS: FIX FOR MOUTH PIECE PROBLEMS IN NOKIA,MOTOROLA,SAMSUNG,NEC,LG,SAGEM, SONNY ERICKSON,IPHONES,BLACK BERRIES ETC

   
First ensure that the mouth piece makes proper contact with the PCB.Many mobile cell phones mouth piece problem get fixed by this singular action especially mobile cell phones products of Nokia, Motorola,Samsung,Sagem,NEC,LG,I phones,Black Berries,etc.
In some cases the mobile cell phone's mouth piece problem is from the 
mouth piece. Testing the cell phone with a known working mouth piece of a similar cell phone could ensure that the mouth piece problem is detected and fixed by replacement.
PCB with a rework station should however be done before using a tiny copper wire to join the ends as most of the mouth piece problems are fixed in this way.
  That the mobile cell phone mouth piece problem could be from related ic and components that are not properly fixed to the PCB can not be ruled out.This problems can be solved by heating the entire PCB with a rework station.
  The earpiece problem could also come from dust on the PCB.This can be fixed by brush cleaning with a volatile liquid.

MOBILE CELL PHONE PROBLEMS: FIX FOR EAR PIECE PROBLEMS IN NOKIA,MOTOROLA,NEC,LG,SAMSONG,SONNY ERICKSON,SAGEM,IPHONES AND BLACK BERRIES.

FIX FOR EAR PIECE PROBLEMS IN CELL PHONES -CELL PHONES

To fix mobile cell phones ear piece problems in Motorola,Nokia,Samaung,NEC,LG,Sagem,Iphones,Black Berries etc the following steps could be taken.

Ensure that the mouth piece makes proper contact with the PCB. This is the most common ear piece problem in mobile cell phones including those of Nokia,Sagem ,NEC,LG, Motorola,Samsung,I phones,Black Berries and others.
       Sometimes it is the ear piece that is faulty.This mobile cell phones ear piece problem can be fixed by interchanging the ear piece with a similar working ear piece.
      The mobile cell phone ear piece problem could also be from discontinuity along the ear piece track or short circuiting. A multimeter should be used to check the ear piece track in order to fix the mobile cell phone earpiece problems in mobile cell phones such as Nokia,Motorola,Samsung,NEC,LG,Sagem,Sonny Erickson and others.
      There is also the possibility that related ic and PCB components are not in proper contact with the PCB.
  Heating with a rework station would resolder these components to the PCB and hence fix the mobile cell phone ear piece problems such as in Nokia,Motorola,NEC,LG,Samsung,Sagem,Black Berries,Iphones and many others.
Dirt on relevant ic and PCB components could also be responsible for ear piece problems in mobile cell phones.As in most electronic devices,dirt could short circuit the system thetreby resulting in the cell phone ear piece problems in question. In order t o fix mobile cell phones ear piece problem,the PCB should be brush cleaned with the aid of a volatile liquid such as methilated spirit.
    Most mobile cell phones problems in Nokia,Motorola,Samsung,Sagem,NEC,LG,Iphones,Black Berries etc can be fixed by re-soldering with the aid of a re-work station and brush cleaned with a volatile solvent such as methylated spirit.
