How to flash mobile phones using JAF, step by step flashing for mobile phones

Main Window

If you see that message in the Status and Results area(4), that means that JAF software is prepared to any operation.

In this first step we are going to begin with the number 1, as usual.

1. Flash Settings

Let’s explain more or less what is each thing in this square and then we will continue with detailed info

In this square we can see four main areas

1.1 Flash files

-In this area we can see the files that can be inside of a Nokia DCT4 phone

MCU is the main part of the software, let say that it’s like the operating system

PPM, the PPM file has mainly the language pack

CNT. This file appeared long time ago in the new Nokia phones and has the media files, different from language areas and branded or unbranded versions

ADSP this file is located only in the Ngage phones mainly and must use the POP-Port or MiniUsb cable to flash this section

APE Variant the following file is only used when flashing APE phones like 7710, 9500, 9300…

APE User Disk the following file is only used when flashing APE phones like 7710, 9500, 9300…

-Below this you can find a new option, Change Product Code

Each Nokia phone has a Product code which varies in language contained and brnded or unbranded version. The product code comes from Factory and can be found in the stick behind the battery.

We use this function to rewrite the product code after flashing. Then the phone will be recognised as we want by Nokia Centers.

-Below this option we have a new option(locked at this moment). If you press INF button, with a phone connected of course, we will have unlocked this feature. This feature looks the INI file of the phone you have connected.

What is an INI file?The INI file it’s a notebook file with extension *.ini that it’s inside any Nokia package installed. This file is based in the different product codes that our phone has.
The INI file will show us in the blocked area the country/Region name and if it’s a branded version. When we will select a package of the list the software will look at the ini file selecting the necessary files to flash the phone.

- The last part of the Flash files guide has four options and will be done automatically when flashing

1)Factory set: With this option marked the phone will be as it has left the factory at the end of the flashing process.
2)Warranty: this will help us to correct any possible mistake in product warranty
3)Unlock:After flash the software will unlock the phone
4)Manual flash: Using this function you can select manually the files that are going to be flashed.
Also can be used when the software can’t search the phone or the ini file. You must press Manual Flash and then Use INI. Then a list with all the Nokia phones will appear, select your and continue as a normal flashing.

1.2 Skip options

We have here four options that will be skipped in the flash operation

- AFP:This means After Flash Process. The process after flashing the main files won’t be done(Factory settings or whatever). It’s usefull if you have connection problem because the usual errors can be found in the AFP.

- MCUID: This allows you to flash a phone without looking at different MCUIDs, it’s dangerous if you don’t know what are you going to do…

- BT: Skip flashing bluetooth Area, it will skip this area because sometimes bluetooth adress can be damaged when flashing.

- AUTH: Will be explained later

1.3 Security&Connection Options

.Use INI it’s used to load INI without press INF button before
.Run INI I think it’s used to use a ini that it’s not in the usual path of the ini files(other harddrive…)
.Load NFP it’s used for non GSM phones and means MCU for this phones.
.Easy Cable is a way to connect some phones-1110,6030,6060-
.RPL 208 it’s a part of the PM file that contains security info. This should be always backup by JAF software in order to avoid IMEI problems.
.FTD ON: It will allow us to use the FTDI chip for a ultra fast flashing.

2. Service Operations

Let’s continue this guide…

The service operation options are used to modify files or manage security options that can be found in the phone. We have 15 options that we will describe carefully.

You must select the option/s that do you want to perform and then press Service button. Let’s describe the functions

1)Read PM: PM or Permanent memory it’s a memory inside the phone with low capacity(I think it’s around 1MB. And it contains security and setup options. With this funcion we will get a copy of the content inside the phone that can be used in case of Software problems. You must put the address that you want to read of the PM(0 to 255)

2)Write PM:It’s the opposite action and will write a saved file. It’s often used to repair phones with problems of Software or Security-IMEI

3)Erase PM: It’s a limit solution to repair a phone with the Software or Security problems. We will erase first the PM and then write a new one. It’s also used to repair imei when changing UEM to write a new PM file for the new IMEI

4)Self Tests: Using this function we can test the hardware parts of any Nokia phone and check if there is any Hardware problem if any of the tests fails.

5)Disp Test: also known as Display Test, we are going to try this function in order to see how is working the screen, if there are dead pixels or damaged screen-leds

6)Upload TUN: upload TUN (tunning) file for CDMA phones

7)Factory Settings:Through this option we will be able to "reset" the phone to the primary state. Data will be lost and any security info will be replace by default info.

Prod. Manager: This means Product Manager, it can be used to reset total time call and other warranty details

9)File Sys Format: Used to remove any user data contained in the phone, this function it’s used on Symbian phones to repair oversize files uploaded(reboot at Nokia animation hands)

10)User Code Edit: This is a useful function. Through this function you will be able to read/write any user code.

11)Upload PP: PP or Product Profile, used in the old DCT4 phones, may be needed after changing the PPM for decustomization, games and apps can not work

12)Download PP: Just a "backup" or a file to upload to any other phone of the same kind

13)ADC Read: Reads ADC values from phone like charging current, voltage, battery current voltage etc.. Very useful in detecting power problems

14)Fun Explorer: It’s a way to see the flash memory of the phone for the user. It will work better using Pc suite as new phones developed can hang the application

15)Warranty reset: Repair warranty imei from original imei, reset repair date to none, also reset life timer to zero (carefull with life timer, it may cause contact service so saving pm is recommended before)
