Some interesting facts. not yet tested on all phone but please test yours and let me know the result here.

1. C:\private\10000850\
contains the mbm file of operator logos

2. C:\private\100059c9\start.dat
some kind of autorun trigger. I couldnt decode this file, but it is it, I'm sure.. Why I think so? Because only after renaming or moving this file, autorun doesnt work. In all other cases apps start.

3. C:\private\10202be9\20001079.txt
this location.. in this text file there is code, and a line which says :

0x00040006 string "clockspeed" 0
0x00040007 int 332 0
on line 41 and 42 of the file.. overclocking possibility maybe?

also in this file is loads of settings with the graphics processor too, maybe even OC this check it out, im not the experianced when it comes to this, and i do have a spare n95 which i wouldnt care if it blows up, i willing to test it

0x00A00000 string "/hardware/graphics/displays/0/ngageorientations" 0
0x00A00001 int 0x00090000 0
0x00A00002 string "ngageorientationscount" 0
0x00A00003 int 3 0

graphics settings there..

4. In Z/private/101f51f2/PKI/96b7db19a4d...../
it has files in called

devicecert.der
deviceprivatekey.der
signningcert00.der
signningcert01.der

or in Z/private/10203636/security/trustroots/device/certificates/
nokia content signing

nokiaonlineca.cer
PCA3ss_v4.der
thawtepremium.cer
UTI_Root.der

click on any of them it says save certificate.
then when you click save it says new cert might be unsecure save anyway? i ant got round to clicking save yet lol

5. C:\PRIVATE\101F4CD2\Content\appshelldata.xml
this file contains the whole menu layout (N82)

6. I found some huge file in phone, c:/private/102072c4/reserved.bin, 4.5 Mb size of plain 0xff.
Deleted it and free up phone memory check if your phone has one.
the files are for FOTA (firmware over the air) coz when i remove it, and go to the device mgr. app it reapears, so its safe to remove it, we wont need it as we never get any FOTA updates.

Excellent info. BTW, I want to add a bit of info to it.
C:\Private\10005A3E\mediaplayer.dat - This is list of Recent clips in Real Player. Those who want to hide what videos they have seen, can just delete it ;)
And for OS9.1 phones (in my N73-1), some of the folders are different. For example, the
C:\Private\100012a5\DBS_100065FF_Contacts.cdb - Contacts Database
C:\Private\100012a5\DBS_100069CC_btregistry - Bluetooth device List
C:\Private\100012a5\DBS_10207216_SWinsLog.db - Instalation log of Softwares
C:\Private\10003a5b\Calendar - Calendar File
Hope this helps someone.

Really good info..
Might be usefull when needed.
Thanks & Rep.

Thanx 4 share dis phoezies,good info.Rep++ 4 u if I cud.

We can all proceed in this thread our debate about overclocking ARM11 processor!:)
Because this thread -> here ([Only registered and activated users can see links]) is REPOST!

Is it safe to delete the Logdbu.dat to clear the phone log, if so does this apply to all those pesky little .dat files you may want to reset...?

Great info PHoeZies:exactly: excellent. Hope more info will release..

thread moved to the new correct section :D

In my case (N95 8GB) i also had a c:/private/102072c4/reserved.bin, 4.5 Mb size of plain 0xff. Which i deleted without any side effects and gained the 4.5 mb of storage,Thanks PhoeZies .:thanks:

thanks bro for info

but why i cant copy any file from private !!! like 101f401d\Logdbu.dat

!!!!!!!!!!!!!!!!

@kask Those files are locked & in use by the system. You can't access them.

hy, what is the point of overclocking phone? is it faster or what?

not really ppl saying its only for ngage performance

if it really affects ngage then there must be files that regulate the real CPU

tested on my n73me additional 4.5Mb from phone mem.....

thanks

Does anyone know which one of the files stores the music player database?

or the gallery cache? i seem to have a corrupted database... i have 10 images on my phone and the gallery shows me 400. each files shows up 20-30 times :/

Does anyone know which one of the files stores the music player database?

AFAIK, the music player database is stored in the memory card (at least if you've stored music in memory card.
On my N73-1, the file is

E:\Private\100012a5\DBS_101FE031_mcv7.mpd

Remember that your Java games' backup files are also stored in the same directory.

how to delete message store in phone memory?????

Do anybody know path to profiles data?? I have backup of whole C:\ but don't know how restore my old sound profiles...

Wonderful post and Nice work PHoeZies !
Thanks for passing the credits to me as well..

;-)

Great work pal!

cheers bro rep added

friends. thus for calendar, i want to transfer it from my n73 to my n82. i tried to copy it in n73 but cannot copy though i already hacked my n73. is it the principle and workable if we copy the calendar to another phone? thank u

Copying the Calendar database is not possible, since it is always in use by the Calendar Server. If you want to backup calendar, use your PC to sync the data with Outlook (or similar application), or, you can use the My Nokia Backup service.

nice info..
What about access points? Where does this informations stored?
Thanx

Can anybody know where the files for the default music player are stored as to know where to increase the headset volume of the mp3 player?

TRUE but always when you enter the device manager and press options the file of 4-5 mb will be created again. So to avoid this accident lol create a simple txt file named simple reserved without bin with Fexplorer and give it read only attribute (of course after you have first deleted the original huge reserved file).

Ok, I've found something:

Hi,
I have a problem. At the contacts, hi have used the detailed labels text for set the name of my contact people, if exists more that one phone for the contact (for enterprises contact). Their labels are not sync with pcsuite and outlook. How preserve their info if the access to dbs_100065ff_contacts.cdb is not allowed?
Agree

Thanks buddy ur tricks r perfect

Some very useful tips
Great job~ and Thanks for the info!

Possibly you can shut down the calender server process on both cells to switch the files. But this is not without risk. Possibly your phone becomes unstable and will crash.
Further more I suggest you first deactivate active standby because sometimes the plugins refer to the agenda.

Good luck :-)
