I have been searching for quite a while (~2 weeks) & have not been able to find anything that helps me do what I want. I have been working on a modified HD2 ROM for my TMOUS HD2 {based on 2.13 ROM}. I have made many changes & have been able to apply most all the mods that interest me the most. There are many references to my problem; but no permanent fixes, & I am tired of the the tempory fix.
The tweak that has eluded me is the "FlashPowerUnavailable" registry entry. I have traced everything within the ROM & could not find the registry setup for this feature. After an extensive search thru all the .DLLs, I was finally able to find the settings. They are located in Battdrvr.dll. From what I understand; the .DLL reads the battery level & automatically inserts a registry key that disables the camera's flash whenever the battery level reaches 20% or less. Even if you delete the registry entry, the .DLL will reinsert it as soon as the battery goes below 20%. Personally I am tired of having to edit the registry everytime I want to take a pic when the battery level is low. The flash adds no real power drain & therefore the "FlashLightPowerUnavailable" is a BS setting that is completely unneeded.
So, here is my question to the community. Is there anyone that can rewrite the HD2's Battdrvr.dll so as to remove any reference to the "FlashLightPowerUnavailable" registry? If it's not possible to remove it completely; is there a way to change the trigger from 20% to 1%?
With the exception of changing graphics & text; I will not even pretend to know what I am doing when it comes to modifying a .DLL file. As such, I have not even attempted to modify this .dll. I have PEexplorer, Restorator, & ResHack on my machine, but I only use them for editing graphics & icons {& occasionally text}. If someone could modify the .dll, I would be extremely grateful. Of course; I'm sure that I am not the only one that would like to have this mod done. Of course; I am also willing to try & learn if someone would want to walk me thru modifying a .dll file.
I have attached BattDrvr.dll in the below .7z file. The zipped folder contains the original module {pulled from 2.13.531.1}, as well as the actual .dll itself. Any help is greatly appreciated.
Thanx:
Hippie
I'm not too familiar with Battery drivers but if you could find a way to have it be associated with Power Saving Mode you could just have power saver kick in at %1..?
But like I said I have no idea how it works..
Sorry for the delayed responce.
BattDrvr adds a registry entry when the battery reaches 20%. It is also readded to the registry upon every reboot. One would need to create an event to monitor the status of the reg entry, & delete/change it when it is activated. Personally; I am not real familiar with the event system & have not dealt with it too much {except to deactivate events thru DotFreds task mngr}.
Would creating an event utilize any system resources? I am trying to do this without adding another footprint to the system {no matter how small}. I know that modding the .Dll will accomplish what I want without creating any new footprints. This is why I posted this question to the community to begin with.
Personally I can't believe that this hasn't been done already. I also can't believe that there seems to be no interest in this whatsoever. I can't be the only one that uses the flash after the battery is below 20%.
I didn't test it, don't have device
What i did was:
Open hex editor, Search for "00 53 E3 35 00 00 9A 1C 37 91 E5 02 00 53 E3" the number before that found should be "14" (which is "20" in decimal) change to "01" (which is "1" in decimal).
I used IDA and HxD
The modded file is in attachment

Little Off topic .. but you seem to know howto hex edit stuff
Been woundering why no one has hexed skyfire so it doesnt check for the skyfire server .. and just goes to google or so other website ..
I was able to get SkyFire working today kinda .. by "tricking" it and made it goto google .. after that .. I was able to surf NP ..
Just a thought
hmmm..i don't know about android...never tried.

Glad I found this. Will try it out when TMOUS sends me my two free HD2s. Thanks. If anyone can report back as to weather it works or not, please do. Might take me a while since mine are on backorder.

Hi all!
I searched for a possibility to activate AGC Microphone after a soft-reset automatically.
But I didn't find anything useful.
The key where the ON setting is stored in registry is
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\AdvancedCPL]
If you change MicrophoneAGC from dword 0 to dword 1 it is set to ON but after a soft-reset back to 0.
Does anybody know if it's possible to export this reg-key make a .cab and put this .cab in the Startup-Folder?
I also found this link http://forum.xda-developers.com/viewtopic.php?t=824 but how to use this programm code?
Another possibility is to create a shortcut to the AGC Control and put it in the Start Up-Folder http://forum.xda-developers.com/viewtopic.php?t=8496, but this gives you only the chance to change the setting to ON not to to this complete automatically.
automatic registry edit
Hallo,
you can automatically edit the Registry using mortrunner, a nice freeware tool. After mortrunner is installed create a file with extention ".mortrun" and put it into the startup-folder. Into the ".mortrun" file you write e.g.:
http://www.sto-helit.de/modules/edito/content.php?id=23#registry
RegWriteDWord HKLM,System\CurrentControlSet\AdvancedCPL,MicrophoneAGC,1
good luck
Contractor,
Ah, yes you must be running Microsoft Voice Command. I too ran into this, and found out that some brain-child developer at Microsoft (who works on Voice Command) decided to HARD CODE the setting of HKEY_LOCAL_MACHINE\System\CurrentControlSet\AdvancedCPL\MicrophoneAGC to 0 (false) every time it is run.
Apparently he/she decided this was the best setting for all of us, and to hell with what our personal preferences (you know, that thing in the control panel) were. Unfortunately, as voice command is in the startup, it resets/overrides this setting with every soft reset. IMO, there is a place in hell reserved for this style of development ;-)
I found that Voice Command works a lot better on my Jam with AGC on.
To get around it, I tranferred voicecmd.exe to my desktop, used a hex editor to replace the "HKEY_LOCAL_MACHINE\System\CurrentControlSet\AdvancedCPL\MicrophoneAGC" string in the exe with "HKEY_LOCAL_MACHINE\System\CurrentControlSet\AdvancedCPL\MicrophoneAGP so it wites to the wrong place (not affecting any real settings. I made a backup, and replaced voicecmd.exe on the defice (don't forget to replace the copy in \Windows as well if using the VCABT hack).
Just search for:
4d 00 69 00 63 00 72 00 6f 00 70 00 68 00 6f 00 6e 00 65 00 41 00 47 00 43
and replace with:
4d 00 69 00 63 00 72 00 6f 00 70 00 68 00 6f 00 6e 00 65 00 41 00 47 00 50
Hope this helps, enjoy!
@ orlando:
Thanks for your suggestion.
Mortrunner sounds very good. I will try it and I think I can use it for other settings as well.
@ dschur:
Everything is correct. I use a MDA compact with MS Voice Command and the VCAPT setting.
As a understand you Voice Command sets the AGC to "0" !!!!!!!
Don't they preach to enable AGC to have the best voice recognition???
You are right that Voice Command works much more better with enabled AGC.
Your workaround to override this setting is great. I'll try it and I think that if Voice Command is setting AGC off, orlandos suggestion would only work if mortrunner is loaded in the startup-folder AFTER Voice Command is executed.
P.S.: Voice Command is located on my SD-Card and there is the workaround to start Voice Command as your last application after a soft-reset to ensure that there is no error message.
orlando, dschur: Again - I'm with your help!
@ dschur
Your workaround works perfectly!!!!
Thx.
I'm interested in the workaround to allow Voice Command to be the last loaded app after a soft reset from the SD Card...
I cannot remember how I set this option. Now I start Voice Command in the main memory. But I think the application MemMaid has this option to set the autostart ranking.
Found some screenshots for Memmaid:
http://www.clickapps.com/screenshots.htm?pid=1505§ion=PPC
P.S.: Sorry, Autostart is the German translation. Startup Folder is the correct one in English....
For those of us who doesnt know too much about all this, mind making a cab installer that fixes this bug?
Cheers
I'll possibly be making an app to sort this kind of thing out. Eventually. Not too soon unfortunately.

I think it's not so easy b'cause it's not like modifing the registry.
You'll have to patch the original MS Voice Command file and post the patched file here?!????
But the other version
(Set the key where the ON setting is stored in registry
([HKEY_LOCAL_MACHINE\System\CurrentControlSet\AdvancedCPL])
in a Sturt-Up folder should be possible.
Hi all,
Do you know a software which let met know what connection type I'm using between GPRS/EDGE and UMTS/HSDPA ?
The E icon tweak doesn't work on HTC TyTN... Thanks!
It has been posted on this forum that you do not need the tweak as the TyTN will show you the network that you are connected to. I would undo what you have done and check that you are really in UTMS coverage.
... or even try a search for other threads on this :roll:
Really?? So what should be displayed if I'm connected to HSDPA?
'U' I believe. Should say in the manual.
Ok, so this is my point.
I want to know if I'm connected to UMTS or HSDPA.
and the same beetween GPRS and EDGE.
I never saw a "E" on my screen ...
Right you are Taron.
I never saw "E" on my TyTN, though I'm sure I was under EDGE coverage.
I think TyTN just doesn't show clearly what precise kind of network you are connected too.
It just shows "G" if you are under GSM network data coverage (GPRS and EDGE).
It will show "U" if you are under 3G network (UMTS and HSDPA).
what a pity, but thank you for the confirmation
One more question http. Do you have the voicemail icon working fine on your TyTN?
I'm on SFR, and when I have a voicemail, there is no icon neither SMS (even if my voicemail is configured to send a notification)...
Thanks,
just so you know there is a registry hack to show the E instead of G when you are on the edge network. this works seamlessly. i dont know for sure but there is probably a similar registry hack for the same thing with the UMTS/HSDPA connections.
Thanks for the tips, but it was said that this hack doesn't work on TyTN
You can use HSDPA in France ?
Yes, SFR is claiming to provide HSDPA in some regions :

I have been trying the same,but in vain.
The reg tweak working for the previous models is not working on the Hermes.
Which brings me to the following question:
Previously with ADDING this new reg key the EDGE differentiation started after rebooting the device.
So some .dll obviously checked for this key, parsed and decoded it and invoked the function in the device.
Question:
How is a (secret) reg key added to the registry parsed ?
Will we find somewhere in a .dll the string "EnableDifferGprsEdgeIcon" (or in the case of the Hermes something else) in real text ?
Can we look for such a value this way ?
Come on all experts here!
I cannot believe that nobody can detail on this here!!!
(P.S. Whenever I try to analyze the ril.dll with a hex editor it just shows zeros. Why ?)
Actually it is not that simple.
First you need a proper ROM dump, with the files intact.
Then you have to know which DLL is responsible for the feature. I don't think it's RIL, it may be device.exe or whatever is showing the taskbar.
Then you need a good decompiler like IDA, which will find the strings.
Keep in mind that all strings on the device are in Unicode so when you look at a string with a hex editor you will see something like this:
65 00 66 00 67 00 68 00
for ABCD
With IDA though you get a special window showing you the list of strings.
there could be difference between what info different operators send to phones connected to their network
so this could explain why ppl expiernce different things connectionwise
help me understand this. i usually just intall 2 cabs on my 8125 after hard reset. one is the GPRS settings for media net and the Edge icon. now that cab only changes my GPRS to icon to E. prob is it dosnt change. now if i install all the extended cab files my connection is ONLY g. that must mean that there is another cab somewhere in there that enables the switch. idk someone help
this sucks. i cant even tell if i have Edge or not.

Hi levenum,
you mean a dump of all files which can be seen in a file explorer (e.g. Resco) but cannot be read, as they are marked ROM or hidden or system, don't you ?
Well there seems to be a tool for extracting such files on buzzdev, called "WM5 Files Dumper".
Unfortunately it won't work with my TyTN as it tries to write the files on to a predefied directory on "Storage Card". Unfortunately in the German version the Storage Card location is called Speicherkarte.
I do not know if it is safe to change this temporarily to Storage Card without destroying all other links and no longer be able to access or start the programs installed on the storage card.
Maybe someone could fix that rather in the "WM5 Files Dumper" where the output directory is hard-coded.
What a painful restriction ! I can imagine that this utility would be valuable for many of us trying to find out more about their devices...
I know that most of the strings are encoded in Unicode.
The Cygnus HexEditor is able to look for Unicode strings, so this wouldn't be the problem.

I know the Athena community is small compared to the Kaiser user base and their video driver bounty is over $5,000 now. But we suffer the same video issues: Lack of dedicated driver support for ATI Imageon graphics hardware.
I am putting my hard-earned American dollars where my mouth is by offering $100 to any developer(s) who can remedy this.
The intent of this thread is identical to the one over in the Kaiser forum; the "rules" are the same. Who's with me?
I'll put in: $25 for a driver that would make the general UI faster. $50 for a driver that would make the general UI faster and would be able to run full-hardware support mode in TCPMP and/or CorePlayer.
Would the drivers be similar so that we could piggyback onto their work? If so I would ante up some cash to get 30fps video @ true 640x480 resolution!
I will up the ante by USD 50.00 more if everything in this thread can be produced by whoever that can make the ati driver.
I'm down for $50.00 USD also. Lets keep this going gang, someone out there has to have some kinda know how in doing this.
Will this ATI fix work? It totally did for my Hermes.

Guys... When I look at my Advantage, EVERY indicator is there that the ATI driver is fully integrated. The HKLM\System\DDraw key is pointing at the ATI driver, the drivers are in \windows and the ATI cfg TXT file is there. This is exactly like my HX4705. I have the US Advantage x7501
Why do you think it *isnt* supported and are now offering cash? If its because of the HTC class action issue, please realize that that is specifically the Qualcomm chipset and, personally, I think Qualcomm is a big piece of that problem. The Advantage is a traditional PXA270+Imageon package that is very well known and understood.
Are people feeling the *driver* isnt there because of TCPMP performance? I really hope not. Picard *acknowledges* and always has that TCPMP and now Core Player are just really not good on the Imageon. He has always blamed ATI and says that now they ARE working with him. You can see the threads at coreplayer.com.
Performance on my HX4705 was horrible as well. I see NO issues on the Advantage from a display performance perspective outside of TCPMP (WMP *always* sucks) Games, scrolling, aspect ratio change, etc are all fine. And I see *clear* evidence that the driver is on the device.
Just look at whats in that "fix" ZIP. Always CHECK before using crap like that. The files are ALREADY there on my Advantage. The config file of course will be different and is a HUGE part of the ATI driver on Win Mobile. Putting a CFG file from a different Imageon down will almost definitely cause you trouble.
Before you offer someone your hard earned cash, please research for yourself how to tell what display driver is being referenced (just look at HKLM\Sytem\DDraw\DeviceEnum and see if it indicated ace_ddi.dll - also look at HKLM\System\GDI\Drivers ), locate the files on your device, learn what those files are and look for the ATI cfg file: atihwtbl0.txt
Here is an ANCIENT thread on the ATI driver on Windows Mobile:

Anything look familiar? On my Advantage at least, the driver is CLEARLY there and loaded.

@mlambert890: Thanks for posting. Iwill happily stand corrected if this is true (and change my sig ). I do see the ATI cfg file on my x7501 but not the reg key you reference. I based my decision to post the bounty on numerous threads complaining about the video performance of the Athena as well ass offline disucssions with other Athena owners. Can anyone else lend any insight?
Weird that you dont have the reg key!
Can you check for me and tell me what you see under:
HKLM\System\DDraw and also HKLM\System\GDI?
Maybe we can make a breakthrough here
Also, do you have access to the TCPMP toture test clip? It was the Matrix Reloaded trailer at 640x480x1.6mbps It used to be freely available from a bunch of places, but now it seems gone.
Im curious what your benchmark results would be on that clip. In TCPMP, what video driver setting are you using?
I have no HKLM, System, Ddraw key at all. I do have Drivers, ATI, Camera in HKLM, System, GDI.
EDIT: I will benchmark the clip if I can get it. If anyone is hosting it, PM me please. Could ATI support be in the x7501 ROM only and not in the others (including derivatives of the HTC OEM ROMs?
Really weird... well, if you're feeling adventurous, you can create the DDRaw key...
Basically, its HKLM\System\DDraw
Under DDraw, another key: DeviceEnum
Under DeviceEnum, another key: ace_ddi.dll
Under ace_ddi.dll I have 3 values:
"Description" , string value, empty
"DesktopFlags", DWORD value, set to 0
"GUID", binary value, set to 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

I've never found there to be any problem with playing video. All my videos play very smoothly, even those which did'nt run at 100%. As long as I don't do the benchmark, I don't even know that it's below 100%
I had said all along that there are many things to improve in Athena, but Video is not on my list. I played "the dog" video smoothly although others are seeing the slide-show effect. In both cases, the speed are quite the same. The effects are completely different. What that tells me is that benchmark speed may not be a good indication of smoothness. What I see with my own eyes is the only thing that matters.
errrrr....
I dont know what people are expecting. I upgraded to the X7500 from a Universal and prior to that I was using a Magician.
The Ameo runs vids better than both those devices. I have my display driver set to ATI imageon with No hardware acceleration within TCMP and Coreplayer and I get GREAT results. It will happily play any 700 - 800 MB DIVX/XVID .avi file which I download to be used on a PC. I dont ever do any conversions unless I have to rip from a DVD.
I think that the Ameo is a great device to play videos on, much better than my N95 and my PSP.
Is it just popular to offer bounties? Best place to do that is to donate to Athena project for more ROM goodness
I want to try that and I can find the HEX code for 12mb as [03 15 A0 03 00 10 8E 05 03 00 00 0A],but I dont know what can I do to 0mb……anyone can help me？thanks
on the artemis tom codon came up with 'change pool size' app (6,8,10,12 i think) but i don't think there's one for polaris - don't try that app for polaris, it won't work, just saying in principle.
i'm no expert at all here and i may get this the wrong way round but...
larger page pool = faster system operation (but less allocated memory for applications ie. 2 or 3 larger apps running at once may struggle)
smaller page pool = emphasis on launching and running programs/applications (but slower system overall)
so i'm guessing (and it is a guess) that a zero page pool isn't possible because this would make the system unusable (you can vary the scale of memory allocation but not loose one side all together), say it's a volume control - you've 0 - 30 in sound but you're only allowed to change between 8 - 24, the others are off limits.
wanted to change my page pool on polaris roms like with tom's app, read a bit about it, pm'd tom for guidance but got no response - probably because all the info is already out there somewhere, just gotta dig and read.
good luck though
(also my memory's **** so as i said before, i could have the above the wrong way round, there's a few posts about though)
You can use OmBy's pagepool changer:

But you can not change the pagepool "on the fly". That means you have to extract the rom file, change the pagepool and flash it.

I want to create very simple calculation app. For example i want to calculate the winning rates of football teams. There is a formulation and there will be a database file. Let say i create 2 files called database.java and calculation.java. I will enter all the football teams skor database to database.java. What i want is calculation.java should take the data from database.java file.
how can do that? is there any sample like this?

Yes there is, but read the doc about storage options first to decide how you want your data to be stored. If it is very simple and small data sets, using SharedPreferences is simple and fast. A text file is quite ugly for this task but will work as well, but if you really have time or will be dealing with large data you'd want to implement an SQL database.
SQL database
