Hack LCD res/timings on Windows Mobile? - Upgrading, Modifying and Unlocking

Hello, I want to know if there is a way to modify LCD timings and resolution through regitry settings or similar on Windows Mobile OS.
I have Asus P750 and I want to replace the LCD. It is an experiment.
Thanks.
Or at least replace in rom pxa27x_lcd.dll to one compiled from me.

Ok, I tried pxa27x_lcd.dll from another CE development platform vendor, and it doesn't work.
The phone hangs on boot screen.
Any help is welcome

How to change startup image on Windows Mobile 5?

I have a Windows Mobile 5 cell phone (not a well known brand or model) and I am wandering if I can change the startup image that first comes on which is a blue Windows Mobile image to my own. I know this is possible because I see all cellular makers do it like I-Mate and so on. Plz help!
If I am not mistaken you need to replace welcome.png in windows folder.
thanks, levenum. this was really helpful!

Create your own Diamond OS?

Hello there guys,
I have a question about the Diamond. How hard will it be to create your own OS for the Diamond? I'm not talking about a full OS, but just for testing purposes only. Like displaying Hello World on the screen. I've adjusted some ROM's, changed the boot screen, played with some applications etc. but i'm looking for a source to display Hello World on the Diamond screen. Just for fun. I know ASM and C and i'm just looking for a good source to brick my Diamond
Where to start?
Greetings,
S
Anyone? I'm not talking about writing your own app, but to start a code after the SPL!

Reading linux/android thread would give you a good start?
That's not an OS, that's learning to write a simple application. The starting point is reading a primer on writing code for Windows CE (The core component of Windows Mobile X). There are several books available on the topic. You'll need an appropriate C compiler, etc. Some books might even include one.
I think that many simple application developers use rapid development tools. Visual Basic kind of things, but for CE. There are several about.

Need app to run at higher res

Hi all,
unfortunately I only know a little of coding and do not have time to learn (full time student AND full time job = little time for extra activities) so I hope you can be helpful..
My father needs to emulate an HP41cv calculator on a mobile device. I found an emulator that does exactly that, only the mobile device is an HP IPAQ with 4.3" 800x480 screen running CE 5.0.
The problem is that:
a) the app loads too small on the screen
b) at the wrong orientation.
b) isnt such an issue as we can solve this by rotating the screen, provided a) can be solved.
to fix a) i think it has something to do with the size (and possibly orientation) of the background bmps, or could possibly be fixed by SCALE code?
the link to the original app is below. source code is attached. first it installs it on PC then installs CAB through ActiveSync or Device Center (im running Win7).

Any help is greatly appreciated.

Acer n50 : Upgrading WM or install Android

Hello everyone!
I have here a quite old (well, perhaps not so "old") PDA, an Acer n50, and I'd like to improve it.
I have seen recently that great people have been able to port Android onto Windows Mobile designed PDAs and smartphones. I even have seen a youtube video guy able to start (just start) Linux on a n50 back in 2007.
So finally my question is : do you think it is possible to install/run a reasonably recent version of Android on this Acer n50? If not or if difficult, can it be possible to install/run a more recent version of Windows Mobile on it? (but honestly, I have a much greater estime towards Android ). I would also like to have some help to achieve this. I have already searched the net for this and Android's developer pages, but I have not found this kind of information or I simply got lost.
I am not a hacker. In fact, I don"t have any experience in this at all. I just know how to fiddle in the console to launch some stuff and have the least of the basics.
Here are the Acer n50's specifications :
Constructor : Acer
Screen : Backlit Color

Microprocessor / Frequency : Intel PXA272 at 312 MHz
Operating System : Windows Mobile 2003 Second Edition
Memory : 128 Mo de RAM, 64 Mo de ROM
Wireless connection : IrDA, Bluetooth, Wi-Fi 802.11b
Audio/vidéo functionnalities : Audio system with integrated speaker and microphone, headset plug
Integrated basic applications : Microsoft Pocket Outlook, Pocket Word, Pocket Excel, MSN Messenger, Windows Media Player 9, Internet Explorer, Calculator, File Explorer, Microsoft ActiveSync 3.7.1, Pictures, Games
Extension port : Accepts SD cards, MMC, CompactFlash
Power : Lithium-ion polymer rechargeable battery
Dimensions (l x p x h) in mm : 120 x 70 x 17,4 mm
Weight in grams : 150 g
Thank you by advance for your help and far by advance.... your patience.
64mb ram is too little for windows mobile 6.5 but someone just did the impossible so you might ask them to cook one for you providing they have the hardware.

Acer n50 never got WM5 upgrade, so there is NO chance for any upgrade from WM2003SE.
To cook a WM6.5 ROM for a device at least WM5 ROM is required as they share almost the same kernel.
There are several posts on the net in french and english about this WM5 upgrade from Acer for n50. But the download link to it seems blocked now by login restrictions or dead links.
Up to now, the up-to-date repository for Acer n50 is this : ftp.support.acer-euro.com/handheld/n50/ there is no rom in there so right now there is no upgrade in fact.
So, as the upgrade for n50 was just vapor or has disappeared mysteriously, is there a way I could install WM5 (through a rom or whatever way that can be possible) over WM2003SE? I have read some people would try this without being sure if it is possible.
By the way, do you think it can also be possible to have the system in french in 5 or 6.5 in someway?
Thank you for your help.
I think that Acer n50 WM5 ROM never existed or maybe Acer made it, but never released it.
As there is no WM5 ROM for n50, there's nothing you can do.
ROMs are device specific, so that means you can't use any other device ROM.
System in french would only be possible if there would be a WM5 ROM.
All right so all possibilities are getting restrained then.
So, two last questions :
Could there be a way for me to install Windows Mobile 5 on this Acer (I guess not otherwise you would already have told me)? It looks weird that people are able to cook WM6.x and not WM5...
Can it be possible to install a version of Android on this PDA?
Too bad it cannot be possible to try to improve this device like it could be for some little bit old computers...

People are able to cook WM6.x because they have a WM5 to use as base. That means if device does not have a WM5, there is no chance for a cooked WM6.x ROM.
You must find a WM5 ROM for n50, that's your only chance.

Basically it's possible, but someone must make it. But I don't think that it will ever happen.
All right then, thank you for your answers.

Swapping ROMs between Acers

Hi there.
I own an Acer BeTouch E400, with Android, wich is fine. But Im starting to miss a little the expanded multimedia capabilities (TCPMP mostly) of my Windows mobile devices.
Looking around I've noticed, that the Acer NeoTouch P400 is THE SAME phone, same exact hardware, only with Windows Mobile 6.5, and I was thinking, does anyone has it? Would it be possible to dump the ROM and install it into mine?
Of course, could be also done the other way around, dump my Android ROM and leave it for those who want it to swap for their WinMO.
Anyone?
Thanks in advance.
