General

- How to use this document

Place the schematics behind this manual. Now you are able to follow these specifictions with graphical layouts and it is easier for you to find the components and measuring points.

- General handling

All screws must be screwed with a torque of 16Ncm. If a higher torque is used, the cover might be damaged. If it is necessary to make a backup, be sure that the data are ok, otherwise it is possible that the corrupt files are responsible for the same faults as before reinstalling the backup.

- µBGA components and broken balls

Special attention to µBGA components: All µBGA´s with the exception of MADLINDA D300 are replaceable and must be renewed after removing. Reflow by hot air fan is not allowed. Check soldering points, remove oxidated solderings (broken balls) carefully by enclosing a few new solders before placing new components. The only allowed way to change µBGA components is to use µBGA rework maschines, approved from NMP (e.g. ZEVAC/ OK International). Only use recommended Fluxtype and an appropriate amount of it.

- Component charactaristics

Some components contain important data. Several described steps are only practicable if you are able to reflash/ realign the Communicator 9210 and/ or rewrite IMEI/ SIMlock in certain cases. Please pay attention to separate notes.

- Realign after repair

Characteristics of replacement parts are different. To prevent additional faults after repair (RX quality, TX power etc.) it is necessary to retune phone values.

Flash faults

PDA does not start/ or Phone backlight is blinking. PDA backlight is working but nothing on PDA display.

Note! If the communictator does not boot up after connecting the battery, pay attention to the Phone display. If the Phone backlight is blinking, refer to the service manual/ Troubleshooting/ Memory Test and/ or Memory troubleshooting, (See blink code table below) otherwise try to flash the phone first.

- If nothing is on PDA display, interchange the BL8 and UL2 modules with working onces, to find out which is faulty.

- If the flash update failed, pay attention to the Flash ID´s (See picture below)

MCUSW:

The flash manufacturer and device IDs in the existing algorithm file do not match with the IDs

Blink code table

2* blinks = Flash 0 or 1 or 2 faulty 3* blinks = SDRAM faulty 4* blinks = Serial Flash faulty

The blinks repeating after 2

Corrupt

FLASH 1 (D352) defect

ASIC: 00020210 CSUM: 9688h

Flash ID 0089-8896, 0000-0000, 0089-8896, 0000-0030

seconds. It is not easy to see.

If the flash 0 is faulty, it is

possible that no blinking sequence is shown on the phone display and the communicator does not boot up.

Corrupt

FLASH 0 (D351) defect

Flash ID 0000-0000, 0000-0000, 0000-0000, 0000-0000

Flash ID 0089-8896, 0089-0096, 0089-8896, 0000-0030

D351 XIP 1 FLASH 0

D352 XIP 2 FLASH 1

D353 XIP 3 FLASH 2

D354 Serial FLASH

To 1) - The flash 1 (D352) is faulty. This can be seen at the second flash ID (0000-0000) in the first case. To 2) - In the most cases D351 is faulty, but also the whole Flash (D351- D354) or D300 MADLINDA could be faulty. To 3) - In this case all flash IDs and MADLINDA are OK.

- If one of the IDs is 0000-0000, check Vcore = 1.8 VDC and VBB = 2.8 VDC at following components:

D351 Vcore D352 Vcore D353 Vcore D354 --- VBB

at C360/C361 VBB at C353/C354 at C362/C363 VBB at C355/C356 at C366/C370 VBB at C364/C365

at C369

- If Vcore is not ok, check Vcore = 1.8 VDC Pin 4 and Vbatt = 4 VDC at Pin 3 of V105 (VBatt depends on settings of power supply at the workbench). (Note! VBatt = VB) Also check surrounding components for shorts or disconnections and resolder or change faulty ones if necessary.

- If VBB is not ok, check VBB = 2.8 VDC at C111. If not ok, check VB = 4VDC at Pin 6 of N102.

- If VB is ok, check N102 and surrounding components for shorts or disconnections and resolder or change the faulty ones if

necessary.

- If all voltages are ok, change the faulty Flash and flash the phone.

- If the fault persists, probably the MADLINDA (D300) is faulty. Up to HW 4.00, the D300 is not changeable because of

underfill.

From HW-ID 4.23 with OSP, the MADLINDA is changeable. (See SB-027)

D354 Serial Flash faults

- SW update not successful (Set Phone power on)

- PDA hangs up

- Error messages appears on PDA display

- If, at the end of flash update, the message “Set phone power on” appears on display (Flash IDs must be correct; see picture at chapter Flash faults), probably the D354 Serial Flash is faulty and has to be changed.

- If the PDA often hangs up or error messages are appearing on PDA display, try to flash the phone.

- If the same faults persist after flashing, the D354 Serial Flash is faulty and has to be changed.

D353 Flash faults

Emulated EEPROM at D353 Flash faulty

- Product Code and HW version not rewriteable

- IMEI 15*0 / Original Serial Number = 656565656565656

- Flashing Error message “Can´t Set factory counter”

- Check which fault has happened using WinTesla menu Testing/ Selftest (e.g. MCU ROM Checksum).

- If one of the EEPROM faults occured, open menu View/ Phone Information and take a look the marked values.(See picture)

Try to flash the communicator with SW 4.13 and promming option Erase Only. Also the memory card has to be updated. If the MMC is not updated some applications do not working well. (See SB-023) For a faster MMC-image update it is a good solution to use ext. drive for MMC. (See SB-018) For Erase Only it is necessary to use the dll version 04.00.00 and the modified RAE3.ini file. (See SB-025)

(Note! Copy the modified RAE3.ini

in the WinTesla/RAE-3 directory. If the RAE3.ini file is not in the right directory the erase only

button in the flash menu is not free to choose.)
