GENERAL
-How to use this document
Put the colored schematics behind this manual.
Now you are able to follow these specifications with graphical layouts and it is easier for you to find the components and measuring points.
-Component characteristics:
Some components contain important data.
Several described steps are only practicable if you are able to reflash/ realign the phone and/or rewrite IMEI/SIMlock in certain cases. Please pay attention to separate notes.
-Broken balls, µBGA
All replaceable µBGA-components must be renewed after removing. Reflow with hot air fan is strictly forbidden!
Check soldering points, remove oxidated solderings (broken balls) carefully by enclosing few new solder before placing new components.
µBGA must be soldered only with NMP approved µBGA-rework machines (e.g. Zevac/OK International). Only use recommended fluxtype and an appropriate amount of it.
-PCB handling & cleaning
To avoid damages of PCB and/or components through electrostatic discharging, handle the module in ESD-suitable cases only. Always wear ESD-bracelets, which must be connected to earth bonding point. Do not make any loose wiring connections or do some other unqualified rework anywhere.
For cleaning only use appropriate materials, do not use scratching or rubbing tools.
Because of organic surface protection (OSP) cleaning must only be done with a lint-free cloth, which may be moistened with DI-water. IPA or other solvent like ethanol should only be used to clean gold pads for spring contacts without affecting the surrounding copper layers.
-Realign after repair
Characteristics of replacement parts are different.
To prevent additional faults after repair (eg. low standby time, loosing network etc.) it is necessary to retune phone values after repair. But never try to cover a fault by tuning.

IMPORTANT INFORMATION
Changing of EEPROM D301
If it is necessary to change D301, take a look at chapter 2 on page 14 “Changing of D301” how to proceed. Furthermore never change D301 if you have no permission to rewrite IMEI – otherwise all phone data will be lost! To avoid further problems send the phone to a higher-level NOKIA Service Center.
Changing of COBBA N800
If it is necessary to change COBBA, you have to rewrite IMEI & SIMlock data and flash the phone! Also RX/TX-values must be realigned.
Changing of CCONT N700
If it is necessary to change CCONT, you have to realign A/D values.
Changing components in RF-part
If it is necessary to change any main component in RF-part (IC´s, oscillators, filters…) you have to realign all RX/TX values.
In case of problems to tune RF-values of GSM1800 band, check in WinTesla Configure/Options if automatic rescan function is activated for the phone. If selected, the band will change to GSM1800 but due to the rescan the phone changes back to GSM900. To solve the problem deactivate the automatic rescan function if necessary.

AM-suppression tuning in NHM-2/5/6
Due to a software failure in the latest NHM-2/5/6 DLL 311.15.00 it is necessary to run AM-suppression tuning in a special way, as described in the following pages. In case you do not use this procedure the AM-suppression tuning values will not be saved and WinTesla will not recognize the new values. So no warning message will be performed.
In the first step you have to activate AM-suppression tuning as usual (Tuning/AM Suppression…):
Click on the “Measure” button to get the next window, which shows the signal values you have to adjust, then click “OK”.
After correct AM-suppression tuning in EGSM900 (RSSI-level shown in the measurement window is < -86dBm) you get the message to proceed the tuning in PCN. At this point do not press “YES” as, differently from the message box, the tuning values will not be saved by choosing this button.
Click the button “Cancel” so that only the window shown on next page is performed on the screen.

To save the tuning values you have to click the “Save” button in this window.
Afterwards start the tuning procedure again by pressing the “Measure” button, because tuning in PCN yet must be done.
Next appearing window is shown below. Press “OK” (it is not necessary to choose correct signal values).
After having done AM-suppression tuning in EGSM900 a second time, press the “Yes” button.
As effect the tuning values of EGSM900 will not be stored (but these tuning values have been stored before). You will be shown the message box as on next page so that you can continue tuning in PCN band.

Set generator to the signal values mentioned in the control box. Then press the “OK” button.
To save the tuning values of AM-suppression in PCN band, do not use the “Yes” button. As in the case of EGSM900 choose the “Cancel” button and click the “Save” button in the remaining window. RSSI-level in PCN tuning must be < -90dBm!
Now AM-suppression has been performed in both EGSM and PCN and you can leave the tuning by choosing “Close”.

CHAPTER 1: HW-CHANGES
Difficulties when removing B-Cover (SB13 / NHM-5)
Cut away the guiding pin of the D-Cover (see Figure 1-1), if customer critisizes bad removal of B-Cover. After this procedure it is necessary to assemble the phone with a torque screwdriver prepared for 30Ncm!
Figure 1-1
Intermittent switch - off problem (SB17 / NHM-2, SB 28 & 55 / NHM-5, SB 7 / NHM-6)
The change of R301 from 2x 2.2 k? to 2x100 ? because of “Intermittet switches off” not needed anymore since HW 0813 on UP4IV, 0814 on UD4, 0815 on UG4 (NHM-5; SB 55), HW 0817 on UW4, 0818 on UW4II and 0819 on UX4 (NHM-6; SB 32) as in the new HW version this change is already done. The change of R301 should be a solution in earlier HW versions only.
All NHM-2 HW versions have the correct value implemented already in production (SB – 017). “Intermittet switches off” could be caused also by old ST flash, i.e. from before Week 02/2001. Therefore it is recommended to use newer ST Flash IC.
Note that SB 28 & 55 replaces the SB 12. Do not use this procedure anymore!

Correct component replacement in UB4_ 10 or later of NHM-5 (SB053) and NHM-6 (SB31)
If changing the power amplifier (N502) & antenna switches (Z502) is necessary, it is recommended to replace with the same type as the removed one.
The information in tables “PA vendor depent RF discrete component mount” and “Ant.sw./diplexer depent RF discrete components mounts” in NHM-5/6 Service Manual must be followed if there is a really essential reason to use different type of power amplifier or antenna switch as replacement
Only the following combinations of power amplifier and antenna are allowed for NHM-5/6:
NHM-5
Power Amplifier |
Antenna Switch |
Hitachi (4350259) |
Murata (4550131) |
Phillips (4350269) |
Matushita (4550201) |
RFMD (4350277) |
Matushita (4550201) |

Power Amplifier |
Antenna Switch |
Hitachi (4350259) |
Murata (4550131) |
Phillips (4350269) |
Murata (4550131) |
Note:
-After changing Power Amplifier, TX Power Tuning has to be carrying out.
-After changing Antenna Switch, Tx Power Tuning and RX Calibrations have to be carrying out.
After the Power Amplifier replacements, additional it should be checked in which constellation R311 and R312 were assembled (marked “X”).
If necessary, adjust the resistors in the corresponding order to the type of PA. Use for it the table below (PA vendor detection) as reference. (NHM-5; SB 25)
This is important because of the differences between the three power amplifier versions in use.
In UP4 Hitachi PA has been used while UD4 includes Philips PA and UG4 uses RFMD power amplifier. Last mentioned is available as spare part meanwhile.

CHAPTER 2: CHANGING OF D301
This chapter describes step by step how to change FLASH/EEPROM-combination D301 in NHM-2/5/6 phones:
If you want to change D301 the first you always have to do is a backup of the phone identity information. Therefore use WinTesla. Under “View” open the window “Phone Information”:
Figure 2-1
If you have no possibility to save this data (e.g. phone does not switch on because of defect D301), it is necessary to give the phone a new identity!
Having saved the phone identity information, you can now remove D301 and resolder the spare part – always use approved µBGA rework machine for changing any µBGA!
Because of the empty Flash the phone will not switch on, after changing D301. So the next action is to make a SW-update. Start WinTesla and choose Product / Open / NHM-5 and press ok. Now you will receive the following message:
Figure 2-2
If you select Yes, WinTesla will start and you can choose Dealer / Flash Phone, and the window shown on the next page appeares:
