Some interesting facts. not yet tested
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 :
Code:
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
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.
UPDATE:
I would like to add the following :
Your access points are stored in
C:\Private\10202be9\persists\cccccc00.cre. Just make a copy of
cccccc00.cre, and restore it to your phone (or send it to another
phone), restart your phone, and you have your access point settings
back just the way they were when you made the backup.
Bluetooth:
Your bluetooth name is in C:\Private\10202be9\persists\10204dac.cre,
your paired devices are in C:\Private\100012a5\DBS_100069CC_btregistry
Bookmarks:
The bookmarks of Symbian's built-in web browser are stored in C:\Private\100012a5\DBS_101FD685_BrowserBookmarks. db.
Calendar:
Calendar entries are stored in C:\Private\10003a5b\Calendar.
Cookies
The cookies of Symbian's built-in web browser are in
C:\Private\101f8530\cookies.dat. Restart your phone after restoring or
transfering the cookies file. If you've told your browser to delete
your cookies, there is no cookies.dat file in C:\Private\101f8530.
Messages:
Your SMSs and mails from Symbian's built-in messaging application are
stored in C:\Private\1000484b. If you've told your phone to store
messages on your memory card, they are in E:\Private\1000484b. Copy the
entire folder, and restore when needed.
Notes:
The notes you write in Symbian's Notes application are stored in C:\Private\100012a5\DBS_101F8878_Notepad.dat.
If you can't delete or replace the file, it's because Symbian is using
it. But there's a workaround for this problem: go to settings, data
manager, memory, and select "back up phone memory" from the options
menu. While your phone is making the backup, you can delete or replace
the DBS_101F8878_Notepad.dat file.
Profiles:
Your profiles are stored in C:\Private\10202be9\persists\101f8798.cre. If you restore the backup, restart your phone.
T9 dictionary:
Your frequently used words in SMS and email are stored in
C:\Predic\101F8615_F.dat. You don't even need to hack your phone to get
into this folder.
really not sure abput that, but i dont think so... and btw i found that file ( c:/private/102072c4/reserved.bin, 4.5 Mb size of plain 0xff. ) and for me its only 15kb no need to delete!
and read text, that file is created automatically, when needed
