As shown in the table above, the IC Flash or Flash Memory is the medium for storing program data MCU (Micro Controlled Unit) and program data DSP (Digital Signal Processor) as the OS (Operating System) software on the phone or the so-called firmware, so Flash Memory be a good role in whether or not a phone system. Language pack or a choice of languages (at Nokia called PPM) is also stored in Flash Memory. The data is stored not only the operating system data alone, there are also pack the data content or User Data Area used to store data or programs by mobile users, including: Phone Book, SMS, Games, Applications, Wallpapers, Ringtones, Foto , Movie, Etc..
Flash Memory currently have EEPROM data that has been emulated in Flash IC. The data is used for storing important data that have been set by the factory's own phone, the data contained in EEPROM include: parameter signal, IMEI (International Mobile Equipment Identifier), SIM Lock, Security Code, ESN (Electronic Serial Number ), MIN (Mobile Identification Code), SID (System Identification Code), etc.. This program data on the Nokia called with PM (Permanent Memory).
In general, the improvement of mobile phone software, there are 4 categories of action, namely:
1.Set To Factory Defaults / Master Reset
How to repair this is by way of returning all phone settings such as the early kepengaturan new phone out of the factory. This improved method does not pass Flashing process but only to reset the phone settings. This process will result in the user data will be lost, data backup should be done first.
Repair method can solve the problems:
* The phone security code (Phone Lock)
* Data users on overcrowded Flash IC
* Error setting
Procedure:
* Phone living conditions, there is no problem while booting
* Connected to Disaaat Flasher Box, phone status "Local Mode" (displayed on the LCD)
1.Format User Area
Basically in the Flash IC is not only stored phone operating system only. Data such as mobile phone users: Data Gallery (Photo, Ringtones, Image), phone book, SMS, Games, Applications, etc.. All these data are stored in Flash IC, if the data is corupt or problematic kenerja would affect the phone, what more when it becomes infected with viruses, so the phone becomes a heavy performance even Hank. By doing Format User Area, Mobile can be fresh again but the risk is all user data will be lost.
Repair method can solve the problems:
* Blank / failure to boot
* Infected Virus
* Application Crashes
* Data users are too full
* Restart
Procedure:
* Connected to Disaaat Flasher Box, phone status "Local Mode" (displayed on the LCD)
1.Flash
Damage to phone software required reprogramming to fix whatever damage symptoms may be caused due to damage to a mobile operating system problems. How to repair this is to delete all data stored in the Firmware Flash IC Mobile, and then written back using the new firmware and in accordance with the mobile phone. Delete and write process is called Flashing or commonly called "Flash".
Phones that do not have a choice of Indonesian can be converted into Indonesian, how not to add the language but in a way Flashing, ie remove all the firmware is stored in the phone and then write back with the existing firmware Indonesian language.
Repair method can solve the problems:
* Upgrade
* Dead Total
* Restart
* Blank / failure to boot
* Blink white screen
* Hank
* Failure of bluetooth
* Contact service
Procedure:
* 1ST Boot OK
* All IC Flash terditeksi well
1.Full Flash (+ EEPROM Area)
Often software problems such as: Contact Service, Blank Motorola, Hank, White Screen, etc. can not be handled by ordinary means such as Flashing Flashing Firmware (MCU & PPM), because the performance of mobile phone software is not only MCU and PPM only, there are some sectors that will The phone supports the performance of such PM (Permanent Memory). PM programmed the phone EEPROM (Electrically Erasable Read Only Memory PROGRAMMABLE), the current Nokia phone is in the EEPROM IC emulasikan in Flash. In PM this stored information data that has been programmed phone by manufacturer vendors such as: the parameter signal, IMEI (International Mobile Equipment Identifier), Security Code, ESN (Electronic Serial Number), MIN (Mobile Identification Code), SID (System Identification code), etc.
There are specific ways of improving the Nokia EEPROM area, before doing Flashing MCU and PPM need to do first Errase Custom, Custom Errase used to remove the Flash IC data on specific addresses or delete entire Flash IC data. Custom Errase Through this we can remove the EEPROM Area Mobile (PM). After the PM completed next Erasing Flash MCU and PPMnya. Next we write back using the File PM EEPROMnya consistent with cell phone type. If you do not have a phone these PM files, you can backup from a normal mobile phone in a way "Read PM" from the same phone Typenya. Until this step will not be normal phone even phone will refuse simcard, will not get the signal because the network status is locked, or Contact Service. This is caused because the phone in a locked status, the phone who has written Pmnya need to be adjusted by cell phone and make unlock process, then you need to unlock.
Procedure:
* 1ST Boot OK
* All IC Flash terditeksi well
* Before doing Errase, are required to backup: RPL / Certificate and the PM is full.
