Nokia 6800 memory limit?

[I_aM_mR_kEE]

Hi,

I have a real problem here..
I have 146 sms in this folder i made. Again, it is a 6800. Now it has reached some limit where it says 'Memory message full'. Is there any way where way I can increase the memory limit so I that I can store more like up to 800? or maybe 4000? or 12000? :)

Hi there :)
This is the same with all those phones which use "shared memory" structure. It is sort of like an harddisk which has been partitioned, just that here is no "Partition Magic 7.0" available.
The phone got a certain amount of memory in a chip, and this is "partitioned" for Phone book, Calendar notes, SMS, and user data (games, ringtones, pictures). Each of those "blocks" has a fixed size.
So it is possible that you can have zero custom ringtones, zero games and and an empty phonebook but still a full SMS memory. Unfortunately you can NOT allocate unused space from another "block" to this one.
Maybe in the future someone will find out how to crack the DCT-4 structure, and things like that may become possible (such as in DCT-3, delete languages that you don't use and put in 25 more ringtones).
Kind regards....

Hi man, thanks for the analogy ... computers are my business background,that's why i found the explanation to be very usefull!
Hope you can elaborate more on other parts of mobile esp. eeprom,flashing, MCU, PPM....etc. if possible.
Thank you in advance,
B.
(p.s. i added you on ICQ)

Hello again :)
Well, i am myself not too deep into the software related stuff... i am more sort of a hardware guy, i have yet only once flashed a phone, but on a homemade flasher! Which was a great success, by the way.
I try my best to put these terms into some sort of computer analogy, but i am here not too sure and i might make mistakes, but i'll try :)

Flashing - this is easy, it is like formatting c: and reinstalling windows. By flashing the phone, it gets almost completely erased and fresh installed, that is why after flashing things like custom ringtones or games will be gone, and it is also the reason why flashing can NOT be done via IR...... while the operating system (!) is being deleted, it can't drive an IR port.... makes sense? :)

EEPROM is a part (seperate chip in older phones, memory-area in newer ones) that holds personal data, of which "personal" means here "phone dependent", data such as the IMEI-number or software version are stored there. The EEPROM (Electrically Erasable Programmable Read Only Memory) can be flashed seperately, in older phones by using a EEPROM-"burner" which programs the seperate chip, or in newer phones with ordinary flashing software, doing a "partial flash" with the correct start- and end adresses. This might be required after a "regular" flash when the phone goes into "Contact Service" or does other funny things, the reason being the Software checking on the EEPROM and finding data there which does not match with the (new) flash version, in particular SW versions or IMEI number.
"Virgin EEPROM" is, as far as i know, an EEPROM with no data in it (!) so after flashing a virgin EEPROM, the IMEI has to be put in there by the user.

MCU (Micro Control Unit) is the "kernel" of the operating system, this controls the functions of the phone. It is the one which is getting updated now and then, when bugs are found etc, similar to LINUX which every so often gets a new Kernel with enhanced functions.

PPM is sort of the "GUI" of the operating system, this is controlled and managed by the MCU and it holds information such as the menu structure, languages, ringtones etc. Like (again!) Linux, where you can change the GUI (KDE or GNOME, for example, on the same Kernel) you can flash the PPM seperate from the MCU, if you want to have other languages in the phone but are happy with it's features and experinece no bugs.

FuBU (you didn't ask this - i put it here still) is a "Full Backup" and nothing but a single file, containing MCU, PPM and EEPROM in one thing. In my opinion it is the safest kind of flash file, as FuBU's normally are taken off a working phone and therefor should work after being flashed to a new one. The reason is because in a FuBU the MCU and PPM match nicely with each other, and they don't interfer, which can hapen with partial flashes. My yet only flash experience was with such a FuBU, which was modified. See FuBU as a Norton Ghost image of your entire HDD on some CD's...... after your computer crashed, burned or you simply got a new one, you can drop in those CD's, run them and after some time the computer is finish just like it was before, with Windows, all programs and even your personal data being in there just like before the crash or whatever.

Same as with computers (back to analogy!) it is recommended, that before you upgrade/downgrade/mess with it, you take a FuBU (Backup) of your (working!) phone. Should the flashing fail, then you can still go back to the stage it was before. You also would not type "format c:" and hit enter, only to THEN remember that you had all your porn pictures, e-mail adressbook and entire mp3-collection on that drive!

Should here be errors, please let me know.... i know that there are also ringtones in MCU's, for example............ i am in no way perfect :)

Kindest regards....
