INTRODUCTION

The purpose of this document is to help service workshop technicians to service products. This service
manual must be used only by authorized service suppliers. The content of it is confidential. Please note that
provides other guidance documents for service suppliers. Follow these regularly and comply with the given
instructions. while every effort has been made to ensure the accuracy of this document, some errors may
exist. please keep in mind also that this documentation is continuously being updated and modified, so
always watch out for the newest version.

CAUTIONS

Please refer to the phone’s user’s guide for instructions relating to operation, care, and maintenance,
which include important safety information.

1. Servicing and alignment must be undertaken by qualified personnel only.

2. Ensure all work is carried out at an anti-static workstation and that an anti-static wrist strap is worn.

3. Use only approved components as specified in the parts list.

4. Ensure all components, modules, screws, and insulators are correctly re-fitted after servicing and
alignment

5. Ensure all cables and wires are repositioned correctly

Electrostatic discharge can easily damage the sensitive components of electronic products. Therefore,
every service supplier must observe the precautions which mentioned above.

GENERAL REPAIR INFORMATION

1. Make sure your testing equipment is functioning properly before beginning repair work.

2. before starting repairs you must observe ESD precautions such as being in your ESD
protected area and connecting your wristband.

3. use gloves to avoid corrosion and fingerprints.

4. cover windows and displays with a protective film to avoid dust and scratches.

5. use a lint-free cloth to clean the LCD.

6. when cleaning the pads use a soft cloth\ESD brush and isopropanol. Do not use a glass
fiber pencil: this scratches the surface and will corrosion.

7. non-faulty mechanical parts(except shielding lids and bent parts or soldered components).
May be reused if they are not soldered.

8. when removing the shielding lids make sure to replace them with new ones, otherwise the
high-frequency leakage can affect the device.

9. always use the original spare parts.

10. check the soldering joints of the parts concerned with regard to the fault symptom. And
resolder them if necessary.

11. remove excess soldering flux after repair.

12. observe the torque requirements when assembling the unit.

13. please aware that some malfunctions may be software related and solved by an update

CATCHER INSTRUCTION

General: The figures in this document help to understanding, and they may not be exactly the same as
showed in your computer. Contact us please when you have any queries.

1 Install the USB driver if not yet.

1.1 Run the USB driver without the upgrade cable plugged into the computer.

Figure 1

1.2 After the installation is completed, plug the upgrade cable into the computer’s USB connector, and then check

the device manager as in figure 2:

Figure 2

2 set the phone to prepare for using Catcher.

Open the phone and input “*#84666364*#” to enter the setting screen. In sequence enter DEVICE, UART, and

TST config. Choose UART1 and Clink done, and then the phone restarts. After the phone restarts, power it off.

3 choose the Database of the phone’s software.

3.1 run “Catcher.exe”, choose Config →.Set Database Path. The figures (figure 3, figure 4, and figure 5) occur in

sequence as below.

Figure 3

- 32 -

Figure 4

Figure 5

3.2 Clink the button “...” in figure 5 to choose the Database file of the master phone or slave phone (for example

“BPLGUInfoCustomSrcP_MT6226M_S01_X6+_FLP_06_12_V3_2-TN-MP-5B-QN” file ). Refer to figure 6

showed as below:

Figure 6

When you examine the master phone’s problems, choose the master phone software’s database file, and when

the slave phone’s problems, the slave phone’s database file.

The database in the phone must be exactly the same as the chose database for Catcher, or the figure 14 will

occur when the Catcher work.

4 enter Logging mode and choose the right COM

4.1 clink the “Logging code” button in the red note in figure 7. Then figure 8 occurs.

4.2 clink button “Configure RS232” in figure 9, then figure 10 occurs, choose the right COM in Port option, and

clink OK.

Figure 14

Figure 15

5.2 connect the upgrade cable to the phone and power on the phone. If the database in the phone is not exactly

the same as the chose database in Catcher, figure 16 occurs (for example, different software versions and wrong

cable connectors lead to the difference between the databases). You have to clink “EXIT” and make the

databases the same.

- 37 -

Figure 16

5.3 The catcher records primitive information as showed in figure 17. Clink the button “clear” in figure 18 to clear

the useful primitive information. Then the phone user carries on some operations to the phone to make the

failures recur. After the wanted failures occur wholly, clink the button “disconnect” in figure 19. You can save the

“.clg” file now as showed in figure 20, and name it. The “.clg” file is that needed for analyzing the failures of

phone.
