magldr rom partition for nand dual boot winmo & android

i just check again cotulla magldr future features development
*support of fixed partitions layout with ability to reflash any partition
so it means we can make rom partition and use 1 partition for android nand boot and the other for winmo nand boot?? aka the real dual boot from nand ??
i read somewhere that winmo cannot read any partition in rom so its not possible... only android and other linux based can use partitions for 2 different build... but that future release point make me think again
what do you think, is that possible?
(well for euro hd2 its almost impossible with 2 partitions each use 256 mb for winmo and android, but tmobile user will have little to no problem with that 512x2)

Actually, current MAGLDR already partitions internal space. For example: seperate partitions for system and data.
Having a fixed layout with the option to just reflash one partition has advantages, for example when it comes to upgrading a build. It would be possible to reflash just the system partition, leaving user data intact.
I don't think this future feature necessarily has anything to do with flashing multiple OS's on NAND.

I hope that in the future we can have both winmo and android on nand... or wp7 and android. Looking forward to future releases of magldr to see what's possible.

If you did not mention already, there are huge problems with the EU-HD2 and Android with having not enough space on the NAND.
After a clean full Android Sense installation, there are only about 60MB left on NAND-space.
WHERE do you want to instasll windows phone 7? I am really sure it will need more then 60 Mb ;-)
I think the most reliable solution would be WP7 on NAND and Android on SD (like it worked with WM6.5 already) or Android on NAND an WP7 on SD (but i do not know if this would work or is in dev-progress).
Two Systems on the small NAND Space of 512mb is not capable i think!

well im thinking about the t-mobile version so 512x2 must be enough to dual boot nand android-winmo (i know its not fair for the euro user... but hey, thats life, i also seriously planning to swap my hd2 euro to the t-mob one if that features come)
also here http://htc-linux.org/wiki/index.php?title=Leo/Magldr
said magldr support YAFFS2 partitions and afaik means support for winmo and android nand boot
so dual nand boot in the future, i think its possible

Yeah, obviously those with 512mb nands probably wouldn't be able to fit 2 OS's on nand, but us lucky ones with 1gb roms may.

yeah the TMOUS useres COULD get that feature
But even if you would have 2 NAND operating systems where do you want to store your userdata?
ok on android it is solved with the NAND & userdata.img builds - but there is a long way to this with winmob / phone 7 - despite this there is the question if it is even possible ;-)
so we should wait and see if the real devs can do this... or not

I was just wondering if there had been any updates regarding the dual booting on NAND? I would really like to try WinMo 7, but not at the expense of losing my tweaked android build.

BUMP: So if there is a T-Mobile HD2, then it may just be possible to dual boot from NAND ? (Considering MAGLDR gets this feature in the future revisions).
Then I will wait for this, in love with HyperDroid-CM7 and cannot sacrifice this for WP7.

Holy shequie mate I'm so with you on the Hyperdroid, it is simply outstanding what I want is a way of dual booting winmo 6.5 (so I can easy stream vids and swap files on my home network) and Hyperdroid CM7 (coz it's the best phone/app experience ever!!) - This would be great, to dual boot, IS there a way, I only have EU HD2 unfortunately tho... But surely if you are running from HCSD it's pretty bloody quick anyway??
Thanks in advance for any feedback...

nand android & android

hi,
i was wondering what is the difference between
nand android
and just
android,
which one is better?
thx
Nati

As I understand it, the first way to run Android on the HTC HD2, was to install it in a special way (described in one of the sticky posts on this forum) on an SD card, and run 2 programs while the phone is booted in Windows Mobile.
NAND Android means that Android is actually installed as the main and only OS in the memory of the phone. That means that Windows Mobile has been completely replaced by Android.
Myself, I am only starting to look into Android, so I am going to do the SD based version first, and check out if it has everything I need (most prominently Microsoft Exchange Server integration of the same quality as WinMo has it).
If it does, then I'm going to switch to NAND android.

You're posting questions that make no sense, nand android and android are the same thing, nand, sd, ram android builds are different .If you read up on android and the difference on builds you will know what it is, and NAND is internal device

Dual Boot Possible with NAND ROMS?

I haven't bothered installing the MAGLDR yet because I am very comfortable with my setup, I have windows mobile 6.5 with android SD, however would it be possible to dual boot Windows Phone 7 with android or Windows Mobile 6.5 on the Nand? Like for the TMOUS1024 devices? I've read on the chinese site for the DFT that its possible but the instructions are very hard to understand. I can't be the only one wondering this or wanting this? Any ideas guys?

I too would love the ability to dual boot, whether it be dual-nand, or WP7 as an SD build (and Android NAND).
Any chance of this happening, devs?

Right now u can dual boot Android NAND and Android SD.
Windows 7 NAND and Android SD but this is too complex. u need to make two partitions on the SD card.

I too would like to still run wm 6.5 as my main os and boot WM7 and Android from my Sd cards. I would also like to know if this is possible.

Is it possible to boot a SD android version via magldr?
Mine freezes if I choose Boot Android SD :/
Using 1.12

I would love to try "Windows 7 NAND and Android SD" even If it is complex. Do have a detailed instruction on how to do this, or know where I can find one?
Thanks.

i think in the future u should be able to dual boot both from nand if u have the 1024leo because the windows phone 7 rom only uses half of the nand

I used this build (http://forum.xda-developers.com/showthread.php?t=801607) for over a month and all I can say is that this is the best Desire HD Sense build I've tried!!! (fast and stable)
So enjoy WP7 Nand and Android SD TOGETHER!!!

Dual boot from NAND only
Well, just the question I wanted to ask (OP, not the hijacking posts):
WM 6.5 (or WP7) NAND partition 1, Android partition 2.
At least that's the idea. Two OS's from the faster NAND memory, rather than the slower SD. Only applicable, of course, to the 1024MB version of the HD2. I know this is difficult, but if the chinese are doing it, why can't we ? This would just make this phone more awesome than it already is.
Can anyone answer if this is possible or not, and if not, why?

What chinese are doing it? I've never seen 2 OS's both on nand on a phone anywhere... even those cheap chinese fakes that claim to run both wm and android are just running android off the sd.
I, too, hope one day someone makes this possible... but not sure if it will happen or possible yet.
Also, HD2 NAND is not faster than a good quality SD in most cases. You might get a little better random access speed from nand, but if you find a good sd, even that is probably about equal. Even WP7 is now using SD cards as internal memory, now, but you need a good SD card that matches the NAND speed for it to work right. SD Android builds run at the same speed as NAND builds in most cases, but most SD builds aren't updated like NAND builds are.
But anyways, I agree that I would like to see 2 OS's from NAND on our phones.

I have a nice tutorial on how to do this. You have to be careful to choose the right SD Android Builds which you can use. There are only a few which are compatibe with SD Magldr. In my thread there are some of the more popular ones which has been converted to work with more coming shortly.
When Nand first came out there were a tutorial which I came across to convert SD Builds into Nand so in theory reversing the process you might be able to convert Nand back to SD and convert that to work with Magldr. It is something I have been wanting to look into for a few weeks now so I might just make it a priority of mine cause any build to dual boot with WP7 would be pretty awesome.

I think its possible, but its difficult because Windows properity OS may conflict with Androids OS so someone would have to configure it so that they both won't conflict with each other.

Thanks for the participation! That chinese bit was mostly to just stir the pot a bit .

A Few Questions about Windows 7

I have been using a NAND Android ROM since they came out and love it, but I'm curious about Windows 7. My questions are as follows:
Does Windows 7 run off the SD card or NAND?
Can I go back to Android if I don't like it?
Does everything work on 7?
Is there a working Pandora hack?
Thanks for anyone's help on this.

1) It runs from NAND
2) Yes, simply flash your preferred NAND via MAGLDR
3) Yes, if you get your activation code to use Live services
4) The jailbreak is called "Chevron" and is cooked into most custom ROMs - but not the very first "Leo70".

The nice thing about the HD2 is you can install wp7 on your NAND, and still boot android off your SD... I went from NAND android back to SD android builds so I could also use wp7, and I've noticed almost no difference in performance and battery life between NAND android and SD android. Only thing you miss out in with SD android is that there's no clockwork recovery... but it's easy enough to boot different builds and make backups with SD android.
WP7 is great, but it's still missing some functionality and apps that android has, so having both is perfect. At this point, I would have a very hard time choosing between the 2 OS's if I had to get a different phone. WP7 grows on you very quickly. Can't wait for MS to put out the update that gives multitasking to WP7.

Any chance to run wp7 from sd totally?

and use android in the nand? i want use wp7 only for make hd videos and use android for all days, let me know please

no.... it's impossible.... WP7 system not operate in that way... WP7 must be flashed to NAND and use SDcard as storage and RAM memory

it's a shame! with android is possibile and with wp7 not

I remember several months ago there was speak of cotulla creating a way to boy wm 6.5 via sd card too but i never heard anything since..maybe just because 6.5 has continued to lose favor

you cant boot WM6.5 by SD card either an doesnt SD android copy its self to RAM? WM2003 might be possible.
The clever chap has got some form or working WM5/6 Emulator working under WP7 if that has direct hardware support, im talking com ports etc, the HD2 would become perfect
course another interesting experiement would be running android via WM6 which is running on WP7, im sure it would run like **** if it was even possible but damn that would be pretty cool

Perhaps what you are thinking about was that there was some talk about a 3-in-1 DFT ROM for the US T-Mobile HD2 that would be able to run Windows Phone 7 or Windows Mobile from NAND memory and Android from the Micro SD card. When booting the phone it would be possible to choose 1 of the 3 operating systems. Other versions of the HD2 (such as the European or Asian models of the phone) do not have enough NAND memory for a 3-in-1 ROM.

is possible install wp7 and android in nand together?

i did some research on this with MS documents and i dont think its possible without it running like **** or having persistant storage issues. WM2003 didnt need persistant storage and ran mostly from RAM (thats why in the good old days if your battery died it reset!) so that might be possible although you'd probably run in to driver issues.
With Android you can more or less change what the OS does, with WM you cant
Essentially SD is very slow, you could build a form of loader that would install to SD but thats not ideal because you need to run the OS in RAM, RAM drives would do, but thats not persistant and WM didnt have a way of mirroring that data back to the SD. In essence, it was never designed to do it, and it was never designed to be changed, so its unlikely it will run from SD unless those issues could be resolved.
I think the 1GB HD2 was going to get a dual boot at one point, and this new emulator looks promising, thats about as close as we'll get i suspect, but then again, perhaps i miss understood what i saw..

I would guess that it all depends on what MAGDLR 2.01 has in its arsenal. Only time will reveal that. And, for sure it would only be possible on the US T-Mobile version of the phone.
