'Permanent Save' through registry entries

Hi,
I have tried to enable Permanent Save through the following registry values:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\AdvancedCPL
CalendarPassColdBoot = 1
ConnectionPassColdBoot = 1
ConatctPassColdBoot = 1
TaskPassColdBoot = 1
But the entries in hh_cb.exe still are unchecked.
How can I get this etries checked through a selfmade program/registry entries?

Cant modify module IAT to hook API

This may be better served in the development and hacking forum. Mods please move?
I am trying to hook the keybd_event API in the keypad. I have found the address of the import entry for keybd_event in the keypad.dll's IAT. I have done so by disassembling the keypad.dll and finding the offset from an exported function to that IAT entry. At runtime, I have added my own service (in order to get my dll loaded into services.exe). When loaded, I use GetModuleHandle and GetProcAddress to find that exported function then use the known offset to find the IAT entry. I have verified that I have the right memory location by comparing the pointer to the module's location using remote process viewer.
The problem is that I cannot read from or write to the IAT. My code crashes when I try. IsBadReadPtr and IsBadWritePtr tell me that I cant read or write to this memory location. Even a call to VirtualProtect to set it to PAGE_EXECUTE_READWRITE will not work. The call fails. How can I get access to this memory?
This simple test code exe shows that all the memory in the code section of keypad.dll is writeable. As soon as I hit section 2 which contains the IAT The call starts failing. Once I hit section 3 it succeeds again (the hard coded PID and address come from remote process viewer and my service dll; I debugged to find where the read calls fail).
Code:
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow)
{
DWORD PID = 239927214, addr = 2061766572, read = 0, sz = 0;
HANDLE pr;
BOOL ans1;
_SetKMode SetKMode;
SetKMode = (_SetKMode)GetProcAddress(GetModuleHandle(L"coredll.dll"), L"SetKMode");
ans1 = SetKMode(true);
pr = OpenProcess(0, 0, PID);
while(ReadProcessMemory(pr, (LPVOID)addr, &read, 4, &sz))
addr++;
while(!ReadProcessMemory(pr, (LPVOID)addr, &read, 4, &sz))
addr++;
while(ReadProcessMemory(pr, (LPVOID)addr, &read, 4, &sz))
addr++;
//ans4 = WriteProcessMemory(pr, ptr2, &mkep, 4, &p4);
CloseHandle(pr);
return 0;
}
What do I need to do to get access? Calls to VirtualProtect and SetKMode do nothing. Any ideas? Thanks!

Nevermind! It seems I was not modifying the correct location. I was trying to modify the table that simply lists imports. I found where the actual function pointer is stored.

SQL CE is driving me crazy !

Hi !
I'm trying to create an application based on location aware concept.
And I'm trying to do a simple query to update some records in my database but it isn't working..
I'm trying to do a simple query like "UPDATE markers set status = 0 WHERE id = 10"
This is giving me an error like this "[1,8,markers]". BUT WHAT THE HELL DOES THIS MEAN ?
If I try to run que query manually it does work ! So what i'm I doing wrong ? How can I activate a (MUCH) more verbose error information ?
This is my function :
Code:
Public Sub turnMarker(ByVal id As String, ByVal status As String)
cOpen()
Dim query As SqlCeCommand = myCon.CreateCommand
query.CommandText = "UPTADE markers set status = " + status + " WHERE id = " + id + ""
Try
'MsgBox(query.CommandText)
query.ExecuteNonQuery()
Catch ex As Exception
MsgBox("Error updating markers !" + query.CommandText + ex.Message)
End Try
cClose()
End Sub
thanks !
EDIT: Nevermind ... found out the problem.
Nevertheless, does anyone know how to make errors more verbose ?

Use SqlCeException as opposed to Exception, and then run through the errors collection....
strX = strX & ex.NativeError
For I = 0 To ex.Errors.Count - 1
strX = strX & "Index #" & I & vbCrLf & "Error:" & ex.Errors(I).ToString() & vbCrLf
Next

do a search for sr.dll. you need to deploy this as part of your app to be able to see exception data when debugging .net ce apps.
or go here -> http://forum.xda-developers.com/showpost.php?p=4862355&postcount=87 .That sample project has got a copy. you'll need to add it as part of whatever project you're making.

Possibility to execute download mode programmatically on Omnia 7?

Us T-Mobile users cannot flash Roms at the minute because the download mode button combo has been disabled.
Maybe there is a way to do this programatically or use a resistor accross certain USB pins like the Galaxy S method.
What's your opinion on this?
Sent from my OMNIA7 using Board Express

Yesterday I wasted some time playing around with the USB diagnostic port (enable in the Diagnosis app, it's the third USB mode option). Both PSAS and QPST can connect to and mess with the phone, so I think if someone knows his way around, the phone can be kicked into Download Mode.
(I only managed to crash the phone in many different ways, but I was really just monkeying around.)

If this can be done it would be great as this is the first phone I have owned where I cannot flash firmware myself.
Might be worth while seeing if everyone with a tmobile uk branded omnia 7 has this issue?
FYI I have included my firmware versions etc so we can try and collate a list of working/non working ones to see what the differences are if any.
os version 7.0.7004.0
firmware revision number 2424.10.10.6
hardware revision number 3.15.0.4
radio software version 2424.10.10.6
radio hardware version 0.0.0.800
bootloader version 4.10.1.9
chip soc version 0.36.2.0

Yes, I tried the *#7284# code and changed the USB Path Control to "Modem, USB Diag" and my phone was recognised by the ROM Downloader but the phone was not in download mode.
I have stumbled upon something which may be what we are looking for though, after reverse engineering the Samsung Diagnosis app I notice there are codes to access 'Operator Specific' Admin areas in the app. Take a look at the attached image.
Now as you can see, the values listed cannot be typed into the Diagnosis app as there is a formula to decipher them. I have the formula but cannot get it to work.
Code:
Private Overloads Function GetHashCode(ByVal str As String) As UInteger
Dim num As UInteger = 0
For i As Integer = 0 To str.Length - 1
[B]num = ((num << 5) + num) + str(i)[/B]
Next
Return num
End Function
Now the bit highlighted in bold is the bit I cant get to work.
It gives the following error:
Operator '+' is not defined for types 'UInteger' and 'Char'.
Once someone can help to get this working, reversing the formula should in theory show us the correct *#000# code combination for each area.

Fingers crossed you can crack it!

I worked on this few days ago, I couldn't reverse the hash function but we had some brilliant ideas how to do it (see the stackoverflow thread about it http://stackoverflow.com/questions/4523553/reversing-a-hash-function)
but I used brute force and extracted some 60 diagnosis codes that you can find here http://www.martani.net/2010/12/windows-7-hacks-all-diagnosis-codes-you.html
and here http://www.martani.net/2010/12/windows-7-hacks-all-diagnosis-codes-you_26.html

This is great stuff martani if there is any way to decipher these ones, they may be worth looking at:
g_ADMIN_GENERIC = 3370684588
g_ADMIN_TMOBILE = 469486183
g_ADMIN_VODAFONE = 474092301
These ones indeed look very interesting and may offer a way to enable ADC or even the Download Mode some people like me have been looking for.

Actually the code is a little misleading, if you see closely, the enum HashCodeTable is used nowhere.
The app waits for user input, after each "tap" on a number it calls the function ParseDial() that hashes the input with GetHashCode then calls the function GetEnumFromList() on this hashed value.
In GetEnumFromList, there is no use of HashCodeTable and even the codes you provided are not hard-coded in this function. I am not sure why they are there but as far as I can tell, to access these parts of the diagnosis app, you need another method than dialing a code it seems

Damn it! Looks like we are back to square one!
Have you seen also on the Samsung Galaxy S the Download mode is disabled on some devices, but some users made a jig where you bridge 2 pins with a certain resistor and it knocks the phone into download mode. Maybe this would work on the Omnia 7 also????

I am hoping for a software based fix rather than hacking together something.

**ALL** diagnostic codes for SAMSUNG devices
I reverse engineered the Diagnostic Menu Application. It contains a list of configuration "Titles" with corresponding hash-codes. I made a tool to reverse the hash-codes to dial-codes. The dial-codes may not be the same as some codes that were already known, but the dial-codes are absolutely correct for these menu. Differences are due to hash-collisions (same hash-code may have multiple possible dial-codes). I just used the shortest dial-codes for every menu.
The list of menu's is very long and I discovered that not all menu-codes were not actually implemented. I guess this list of codes is used for all Samsung devices (possibly also for Galaxy S and older Windows Mobile devices). So not all dial-codes may actually work on your device.
WARNING!! The menu's can configure low-level settings of your phone. And if you don't know what you're doing you may brick your device or maybe hard-reset the device and loose all your data and settings. Or you may faulty calibrate your sensors. Be very, very careful with experimenting!! I will not take any responsibility for damaging your device in any way.
I would personally be very interested if anyone finds a way to get the device in download-mode by using these menu's (I have a bad bootloader which does not let my Samsung Omnia 7 go into download-mode to flash it to a newer firmware).
By the way: the admin menu's are NOT implemented on the Omnia 7 :-(

Can you share how did you reverse the hash function? I worked on this some time ago but finally just brute forced it to extract the keys.

I would also like to know how he reversed the hash codes! I tried for hours and had no luck!

Haha.. Well, I first tried to calculate the original dial-codes, but that seems to work only for dialcodes shorter than 8 digits (5 bits per digit, 32 bits hash-code = 32 / 5 = 7 digits + 1 digit for the extra add):
Code:
uint hash = 0; // enter hash here
string DialCode = "";
while (hash > 0)
{
uint digit = (hash % 33) + 33;
if (digit > hash)
hash = 0;
else
hash = (hash - digit) / 33;
DialCode = Convert.ToChar(digit) + DialCode;
}
return DialCode;
But this does not work for long dial-codes. So after that I just made a little program to brute-force it. I copied the enum with menu-titles and hash-codes to my project. Then I used reflection to populate a sortedlist. Then I started to brute-force and check all dialcodes for their hashcode and see if it exists in the list. If it exists, I add it to a textbox and remove the item from the list. That's it. So it is not really reversed, but my program took about an hour to get dial-codes for all the hashcodes in the enum.
Code:
SortedList<uint, string> hashCodes = new SortedList<uint, string>();
int l = typeof(HashCodeTable).GetEnumNames().Length;
string[] menunames = typeof(HashCodeTable).GetEnumNames();
for (int i = 0; i < l; i++)
{
try
{
hashCodes.Add(Convert.ToUInt32(Enum.Parse(typeof(HashCodeTable), menunames[i])), menunames[i].Substring(2).Replace('_', ' '));
}
catch { }
}
char[] chars = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '#', '*' };
for (int length = 1; length <= 20; length++)
{
ushort[] digits = new ushort[length];
for (int i = 0; i < length; i++) digits[i] = 0;
while (true)
{
// calc hash
uint hashCode = 0;
for (int i = 0; i < length; i++)
{
hashCode = ((hashCode << 5) + hashCode) + chars[digits[i]];
}
if (hashCodes.ContainsKey(hashCode))
{
int m = hashCodes.IndexOfKey(hashCode);
string str = "";
for (int j = 0; j < length; j++)
str = str + chars[digits[j]];
textBox1.Text = textBox1.Text + hashCodes.Values[m] + " = " + str + " (0x" + hashCode.ToString("X") + ")" + Environment.NewLine;
hashCodes.RemoveAt(m);
}
// increase
digits[length - 1]++;
for (int k = length - 1; k >= 0; k--)
{
if (digits[k] >= 12)
{
if (k == 0)
break;
else
{
digits[k] -= 12;
digits[k - 1]++;
}
}
}
if ((digits[0] >= 12) || (hashCodes.Count == 0)) break;
}
if (hashCodes.Count == 0) break;
}

Excellent stuff! Thank you for this very interesting code snippit!

WP7 diag codes
martani said:
Actually the code is a little misleading, if you see closely, the enum HashCodeTable is used nowhere.
Click to expand...
Click to collapse
This is because the compiler optimized out the switch statement and compiled the constants into the IL code for the hash codes.
Within the main switch statement where keypad entries are evaluated there are ~112 codes and I've reversed all of them. Writing hash algorithms is not straightforward and it's quite a simple one, since my app captured 2-3-4 variants of keycodes for the same hash value.
Regarding the most interesting entries at the top of the enum the ADMIN_ entries...those hash values are not handled by the application, maybe Samsung has another diag app or a different app which is using the same method.
The other thing I can think of is there are APIs in the diag app which one is sending the hash of a keycode to the given driver...I tried that but the ADMIN stuff did not worked that way either :-((
If anyone is interested I can post the resolved codes, but not sure if I can post it in the forum or not ;-)

Regsitry entry to enable SLDR mode
I found this definition in B44C7A84-5068-4b43-A1E5-F870A80F6FF8.rgu:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\UsbFn]
...
"OsMode"=dword:0 ; 0 for Main OS, 1 for SLDR
....
Is the download mode == SLDR mode?
Since maybe we can set this entry "somehow", and upon next reboot we will get into download mode so we can flash the device?
So the question is, what is SLDR mode? Secure Loader mode? I don't know this, a more pro in this area should help out ;-)
UPDATE
I was able to read the value (0) and write it back (0). Did not tried to write 1 there

Hey guys. I know this thread is about programmatically enter downloadmode, but I wanted to try the 301k resistor trick and I can confirm it works on Samsung Omnia 7.
I used this guide. If you're gonna do that too, then you should pay attention to these things:
- The guide refers to pin 4 and 5 being closest to the headphone socket. But on the omnia 7, the headphone and micro-usb sockets are the other way around if you compare it to the Galaxy S. The guide is for the Galaxy S, so you should really pay attention to which pins you solder the resistor(s). This is the best picture on how you should solder the resistor(s).
- Many micro-usb cables have no wire for pin 4. Some connectors don't even have a pin 4. You should first verify that your connector has all 5 pins. If you only have 4 wires, then you have to dismantle the connector and solder directly on the back of the connector.
I switched off my Omnia 7. I plugged in my jig and it went to downloadmode immediately.
It's late now, so I will see tomorrow what I will be going to flash on it. There quite a few roms and I'm not sure which one I should use. I have to figure that out first.
If anyone has questions about how to make a jig, just ask. I know how to make one now.

You should post pictures, how to make such a cable. Thanks

The picture I linked to in my previous post look pretty clear to me. It shows what pins you have to use. The guide I linked to contain all the other necessary details. If you have any specific questions about something that is still not clear, you can ask me.

Tools for Logging processes, like WinComm, Portmon, QXDM...

Nice and easy Tool:
http://www.softsea.com/review/Portmon.html
Maybe someone saw/know the yellow Message "UPLOAD data to pc"...
How to catch Data if "Bluescreen" comes and "UPLOAD data to pc" message appears?
It seems this nuke my Portmon...
Any suggestions please?
Maybe I'm blind or these are not stored in Debug folder...
Best Regards
Edit 1.
Changed title.

If you have a Windows XP machine left, try this to watch the serial port:
ups, i can't post links here. Google for serialmon dot com .....
It's output is a little easier to use than portmons. In general, using a serial port monitor to watch the communication between wave and pc, seems to be very unstable business.

Now I'm closer...
Taken info from Samsung GT-S8500L Wave Training Manual SW.ppt...
If someone needs the Settings to attach handset correct, ask me... in this Thread.
Best Regards

Could you post the settings, found this earlier, but couldn't do anything with it.
Thanks

I'll try to describe "short" steps.
1.
You have to be sure that Debug Level Middle is on. Please read here:
http://forum.xda-developers.com/showpost.php?p=10616930&postcount=3
Level Mode High shows more events...
2.
If you have access to Internal menu:
*#7092463*#
Maybe set to High or go to Debug Settings... described in ...Manual SW.ppt...
site 15
3.
Start WinComm and now check site 16 on *.ppt manual. All settings are on Picture.
4.
On handset I have choose Debug Mode instead Kies... this thingie if you plug cable into Wave... maybe go to Settings and set to ask by connection instead Kies
5.
Be sure you choose the "second" Port. Now Wave have 2 COM Ports activated.
Second one is for incoming Data.
Hope this helps an little bit.
If problems ask again.
Then I'll try to make some Screenshots or maybe some other hints...
Best Regards

Ehm have you found that Wincomm2010.exe
Click to expand...
Click to collapse
2010 no, but 2009 like in this Picture is attached.
WinComm2009.zip
Best Regards

Handset
Under Settings->Connectivity->USB->Ask on connection
To have chance to set USB Debugging
Wincomm
I will try later maybe Open or Close for connect to the port.
Important is to choose second COM Port...
Also important to activate UE Awake in settings like on Picture.
As it seems initial AT command is mandatory AT+WINCOMM...
Best Regards
P.S.:
I'm using XP 32 Bit... no other OS tested by me.

so now you can upload fw files from the phone or what???

Now you could see internal process like Key press, which files involved... etc...
Many high technical stuff. But this could help to understand more.
For me it is very usefull.
I will soon attach few Log examples... maybe then more clear.
Best Regards

i don't suppose that anything can be done if *#7092463*#
doesn't get me a menu?

http://forum.xda-developers.com/showpost.php?p=12798896&postcount=5
Please read deeper this post and follow Links.
As Internal menu is disabled if you flashed ever Rsrc2_S8500_xxx(Low).rc2
Or if you not use Multiloader, then Kies did for you.
This is internal stuff, you have to "unlock" few things before... so read my instruction prior posted.
Please. This is more for advanced users. This is NO must have for all users.
At your own risk.
Best Regards

It seems also good idea to set Trace Level to High... in Internal Menu.
Best Regards
Edit 1:
Seems difference between Firmwareversions...
On JE7 I can see logging if handset is "off" if battery charge Animation is on.
Then if you press ON you can see parts of Booting sequence...
On JL2 I see first something, if Wave is fully on...
Maybe in higher Build some things disabled/removed...

There are three jwc_properties.ini files. 1st one in Appex>SysDefault>Java>jwc_properties.ini, 2nd one in Exe>Java>jwc_properties.ini and 3rd one in SystemFS>User>Exe>Java>jwc_properties.ini. Use trix, TkFile explorer or Stune. Personally, I think the first ini file is fore the default java apps on the phone. I think the 2nd one is useless since I didnt see any java apps in that folder using stune. I think the 3rd file is for user installed java apps. I dont know since I am still in the process of modifying the whole bada firmware as far as possible and then I will later flash my phone with my custom firmware. Maybe you could help me tell which files are used for what? Ok, enough talk. Now here are settings for heap sizes that I used: (You can find heap settings at the end of each file)
## Limited MVM configuration
MAIN_MEMORY_CHUNK_SIZE = 82313216 # (78 * 1024 * 1024) + (500 * 1024), 78.5MB
JAVA_MAX_HEAP_SIZE = 65011712 # (62 * 1024 * 1024) + (0 * 1024), 62MB
JAVA_MIN_HEAP_SIZE = 10485760 # (10 * 1024 * 1024) + (0 * 1024), 10MB
MAX_ISOLATES = 4 # AMS Isolate + One application
The last setting, MAX_ISOLATES is the max number of java apps you can run simultaneously while paused. My setting allows 5 apps to run simultaneously. (Remember, Max_ISOLATES value should be one less than the desired value.) Earlier it wave could run only 3 apps.
I am surprised the Samsung provided low java heap sizes for such a good phone! Anyways enjoy!

Thanx astrotom
