[DEVS needed](Camera / Multitouch / Sound).. getting closer to native WP7 experience - HD2 Windows Phone 7 Development

Guys (and girls ... if any are reading .. )
After some tinkering about (for days now) with Mango build 7720 (Thanks again YUKI + XBOXMOD!) I can confirm that the many of the issues present in Mango Beta are now gone ... Ok granted the MicroSD gets encrypted but its not meant to be removed on an original WP7! You can refer to Yuki's thread on how to unlock your MicroSD card if you don't fancy the likes Microsofts OS and want to revert back to Android .....
Now, it's a known fact that multitouch is an issue together with sound and camera. I was unable to find solutions to this issue. This thread seeks to ask / reply and hopefully implement some of the issues which remain for us to make the HD2 and hopefully run Android and WP7 natively without the abstraction layer present in the secondary bootloaders.
Question 1 - I am aware that CLK runs android only. Are the sound / camera / and multitouch issues present in WP7 also present in Android NAND roms running on CLK ?
Question 2 - How possible is it to modify CLK to run WP7 if the answer to above is NO?
Question 3 - If the issue iies in the secondary bootloader drivers (if any) ... Is there a way to modify/contribute for further development on them?
If we resolve these the HD2 would truly be a remarkable piece of hardware running virtually any OS. Presently the multitouch issue kills some of the enjoyment on WP7 ... and the source sound input gain is too high.
I really wish if we could get some serious thread going and if anyone is confident that he/she can help resolving the driver issue, feel free to pm me. I am a software developer (c#) if this can help in any way. Have been using it some years now on a daily basis. I am willing to provide my help. I hope that anyone could help along maybe we create yet another open source bootloader which does the trick.
Hoping to hear from you so we get something going ...
Regards
Al
I would really like to hear from some devs I am more than sure that the community would be very grateful.​

I suggest that you all Sign this Petition.. Kindly inform all fellow HD2 owners to sign it ... especially if they were impressed by WP7 on HD2.​

Question 1 - I am aware that CLK runs android only. Are the sound / camera / and multitouch issues present in WP7 also present in Android NAND roms running on CLK ?
No there are some issues in camera and sound with android but is related to incomplete kernel. They are not related to each other for example no multi touch issues on android. All those issues are related to not perfect drivers hd7 is using another touchscreen panel I guess and maybe different speakers and camera. Anyway those drivers are complexed to write because we dont get source from microsoft on how to write them.
Question 2 - How possible is it to modify CLK to run WP7 if the answer to above is NO?
Theoritically yes but CLK is designed to load an linux kernel. So if we want that we need to write a complete new bootloader.
Question 3 - If the issue iies in the secondary bootloader drivers (if any) ... Is there a way to modify/contribute for further development on them?
Yes but you need to go backt to Windows 6.5 and read out the current drivers and port them to windows phone 7 properly. But you will need a JTAG for it and you must be very skilled.
If we resolve these the HD2 would truly be a remarkable piece of hardware running virtually any OS. Presently the multitouch issue kills some of the enjoyment on WP7 ... and the source sound input gain is too high.

Hope this make some stuff clear.

You talk about a sound issue.
If your talking about the sound being too high, then a cab can be downloadeed to fix this. Doesnt limit the maximum volume, just reduces the minimum and puts bigger steps in placce.

We need an asm developer for try to fix multitouch problem... or the source code of driver...

---

Multi-touch is a bit better for me (don't know if the games which need two screen pressure work I didn't tried yet) but in Bing Maps and IE9 it's working most of the time.

---

Just hope that's will come soon, I cant wait it !
However, I also hope the Mango will worked with flash and include more apps in the marketplace.

Its not working in any of multitouch Games.

Nice thread,curious to See the answers, definitely camera is a big issue for me, hope it get fixed soon.

Dont forget the need to use the "batterytrick"
good thread by the way

Unfortunately the thread won't lead to anywhere. Development on WP7/7.5 is not like development on Android. WP7 is closed source and so is the drivers.
So unless HTC themselves step in or a developer hacks new drivers up(which won't happen). We'll never see a native WP7.
We're using all the stuff that was leaked from the original LEO ROM. Also, CLK with WP7/7.5 boot support would not change this. And no, all these problems are not present in Android. But that's because the developers have more tools and open source code to work with, something we don't have.

Try to think positive man... Have you ever seen the arm listed file? We need to find a timer between the two finger... would not be so so so hard... but only hard...XD

Hi and thanks for the feedback. With a negative attitude the thread will lead to nowhere yes. That was what people said a year ago when they said that WP7 will never run on the HD2 but the devs ultimately got there. Thanks for answering the question re the Android drivers though.
You are RIGHT that the drivers in WP7 are closed source drivers ... so is MAGLDR. Rewriting another bootloader (if needed) which does not have all the frills of MAGLDR but which is open source could be a possibility.
I am not interested in getting into the WP7 ROM and modifying the drivers built in ... We have to use a technique similar to what they use when creating emulators by reverse engineering ... The most die hard emulators out there such as some of the Playstation emus out there were all closed source but it did not stop the devs from doing a proper emulation of the console.
I'd really appreciate if you could be more specific when you said that we are using the stuff which was leaked from the original "LEO" ROM ... as far as I know, is it not the Schubert which was leaked? Correct me if I'm wrong ... We got too far to give up just now...
Multitouch games do not work .. with the current Multitouch driver .. mainly due to the finger position bug .... This is explained in detail on youtube.
Sound is distorted because the input gain is too high ...
Let's not speak about the camera for now ... I think those are the two major issues which need to be remedied for now. Hopefully this thread will get us somewhere.

Good initiative ! I hope we can make things work.
Also for those with the negative attitude...if you dont have anything good to say...dont say !

That is not exactly fixing the issue... It just modifies the maxima and minima ... The sound (input gain) is too high making it sound distorted from the HD2. The fix does remedy this a bit but its ... erm not really fixing the problem.

do think this would be a good idea, but its not being negative pointing out the obvious issue, its being realistic.
you see the point you made on MAGLDR and WP7 running of the HD2 is mute, and im not sure you fully understand its use, there are fundamental differences in making WP7 believe the HD2 is a native device and changing the actual drivers, you see, the SPL for the HD2 was opened up a long time ago with HSPL to be put in place which pretty much allowed us to do anything, the next critical piece was MAGLDR, which sat on top of the HSPL which gave us the potential to install android then WP, both HSPL and MAGLDR are very much programed by folk on here, they were not "hacked" or copied, they are closed source as you put it but they are built for a purpose of doing exactly what they do, enable custom ROMs, for WM, Android and WP to install. But that’s not the issue, the issue is a driver
To be clearer on the matter, IF WP7 had never been tested on the HD2 initially then we would never have had it.
The reasons for the bugs we talk about are because we have test drivers that were never supposed to see the end user. Had we not had that opportunity with the drivers on the HD2 then we would have been up the creek with it.
There are only a number of possibilities to get what we want
•HTC/OEMs go out of their way to finish the HD2 WP7 drivers and give them to use
•HTC/OEMs gives us the Relevant code and tools to do it ourselves
•We find native Windows phone devices that uses EXACTLY the same hardware which we can borrow
•Finally, the wildcard, someone who happens to know how to program for the hardware in question comes to help us.
That is it im afraid, its not being negative, you want to know what we need to do, well, there you go, the chances of HTC etc helping us are almost non-existent, finding devices with the same hardware, well i think we have more of a chance of HTC giving us them, BUT thats more to do with the very old digitiser we have, less so with the other hardware elements, so there is a possibility there.
Finding someone who can actually build a driver from the ground up? its possible, but short of putting adverts out on every developer website asking for help its not likely we will find one from this thread alone.

ur right...man sometimes i so feel like bombarding Drew Bamford (product design HTC) emails about windows phone 7 and androi on HD2 and force him to be convinced to make drivers for us....its our right
but then again...can we really ???

I'd say... let's do this! If we get enough people, and those will send emails like everyday, then why not? There's nothing to lose

---

IF, and its a big IF, we are going to get it working better its going to need ideas like the comment from backlashsid to get unofficial support from these companies
In my humble opinion there is little chance of getting anything else working better without the support of people in the loop, essentially that means HTC and Qualcomm, but remember that by getting the HD2 running WP7 we are costing them money in lost sales, so there is little incentive for them to support us in an official capacity, what we're looking for is an insider!
it doesnt hurt hunting for new devices with the same hardware but its unlikely anyone would use old gear.

This would be nice so then we (as the community of XDA) can show off our HD2's as the beast-mode phone and bestest phone ever!
