hello guys, newbie on the block here...

being able to port wp7 is surely one of the reason that i bought hd2, but i don't have the courage to do it back then so i played around with android sd build (playing safe) for a few months...

now i'm bored with android and also this tutorial video. i'm willing to try dual boot wp7 and android, but the question is does it worth doing it?

can anybody gives me a reason to port wp7?

can it play xbox live games?

can anybody tell me the pro's and con's of wp7?
[HD2 Windows Phone 7 Development] daniel_kiefer:
You can play WP7 games and get gamer score for them. WP7 is a pretty snappy OS, the downsides are that it's the new kid on the block, so there's not much for customization and app support. Other than that it's nice. Very streamlined. And since you already run android on your sd, there's no reason not to dive in. Just back up your sd card before flashing anything and setting up your partitions.
[HD2 Windows Phone 7 Development] Audio Oblivion:
Just to let you guys know... i tried with xboxmod's latest build and no issues... couldn't get past the storage error with DFT's latest build though. Thanks again!
[HD2 Windows Phone 7 Development] collins521:
Finally got this to work last night with a MIUI SD build and W7, only problem I'm having is the wifi on both sides blows. Android won't connect and W7 is hit or miss. Anything pointers on getting it to work better? Do I need to reflash everything?

Cannot have FAT16 partition

Dear All,

I have a very strange issue when trying to install dualboot.

After installing WP7 and resetting the phone as requested.

When I put the SD card in Easeus Partition Manager what I see is only 1 partition 200MB unallocated.

no FAT16 partition

no unformated partition

I try this operation several time with same result with 2 different SD card 8 and 16G

- HD2O© v1.14 WP7 BUILD 7.0.7392.0 NODO COPY&PASTE from HD2Owner

-SD card SDHC 4 fron Kingston

Please help
[HD2 Windows Phone 7 Development] daniel_kiefer:
I was having that problem too, I figured it was my card adapter. I used mass storage in magldr and it worked for me, but I've heard that some people have problems with it.
[HD2 Windows Phone 7 Development] webvan:
Yes I was having problems with that too at one point, also WP7 was seeing varying sizes for the microSD, not sure why.

What's the best way to upgrade WP7? I did it once and it was a big hassle...or rather I had to start from scratch after copying the Android partition to my hard drive and then copying it back. Worked ok but took time. Is there some kind of backup tool for WP7? Can you keep the existing partitions on the microSD card?
[HD2 Windows Phone 7 Development] daniel_kiefer:
As far as I know there's no backup yet.
[HD2 Windows Phone 7 Development] webvan:
Thanks,even less of an incentive to update then...

Has anyone tried booting into Android SD from MAGLDR without the SD card prepped for WP7/Android and not have it messed up by WP7? Reason I'm asking is I'm using an 8Gb card and am starting to feel the lack of space in Android. So I was thinking of copying my Android partition to a fresh 8Gb card and use only that.
[HD2 Windows Phone 7 Development] daniel_kiefer:
I haven't tried it, but it seems it would work in theory. As long as the folder you set it to boot from is there.
[HD2 Windows Phone 7 Development] russsauntry:

Fantastic video and instruction. All working well except for Data transfer over 3G on Android, any ideas?:confused:

Upgrading to a newer Windows Phone 7 Build?

Hi guys,

if i want to upgrade to the newer Mango build(http://xdaforums.com/showthread.php?t=1157535),do i have to repartition the sd card and go over all the steps in the video,or can i just flash the WP rom without it affecting the ability to dual boot properly?...p.s:i think its the former,but just want to make sure:)...thanks alot!
[HD2 Windows Phone 7 Development] nizaamh:
Hi. When u flash wp7 it resets and partitions the sd card again so u will have to start all over again.

Question guys: I also updated and changed wp7 rom ( XBOX ) and loaded a new android rom ( jag miui july rom ). Ok so when i flashed the wp7 rom first it workes fine. When I load the android rom and set the (other : as primary ) the android works fine but going back to wp7 it says the card is either damaged or not compatible. ie. the wp7 wont work.

Nizaamh:confused:
[HD2 Windows Phone 7 Development] webvan:
Looks like the SD got modified at some point :-(

Thanks for the heads up about Mango but WP7 has been so useless to me and also wasting 50% of my SD card that I'm about to try running Android alone on the SD or even in NAND...
[HD2 Windows Phone 7 Development] spikespencer:
Has anyone tried to do with with Mango? There are no longer a FAT partition when I tried it just two Other Partitions. I tried to make it work and managed to get a FAT32 but as it is not the first partition I cannot make Windows see it. Has anyone gotten this to work with Mango?

This seems to work http://xdaforums.com/showthread.php?t=1082343.

[HD2 Windows Phone 7 Development] Barmalei:
Thank you for your excellent video!

The video is absolutely fantastic, I followed all the instructions, and it works very well. I am running WP7 Mango (blackSideSeven v2.0).

I only wish I did that (dual boot with Android) long time ago, but I guess it always seemed much more complicated than it really is, thanks to these instructions by 96edwy. You're the man!

Now I need to start exploring Android. This already solved one of my main problems with WP7 which does not have Wi-Fi tethering capabilities.
[HD2 Windows Phone 7 Development] webvan:
...or the ability to connect to WiFi AdHoc networks. I used WP7 a few times but honestly it doesn't have much going for it compared to Android. I copied my Android partition to a new microSD card to have more storage space and the installation still works (we were wondering about that a few messages above) and even if it boots into WP7 by accident the microSD card doesn't get totalled, WP7 just says it can't boot and needs to be turned off.
[HD2 Windows Phone 7 Development] SamStone:
I followed the steps and my Windows 7 works great but when I try and boot into Android I get the HTC logo, then the Cyanogen screen comes up, but then I get a popup that asks to continue using device.android.com or setup menu and my screen is frozen and it won't let me continue. My Win7 is YukiXDA's and my radio is 2.15.50.14. Anyone have any suggestions and will this radio work OK with the SD Android Cyanogen build?

Thanks
[HD2 Windows Phone 7 Development] SamStone:
I finally got it working, just a few mistakes kept it from bewing as smooth a install as it should be, mistakes on my part of course :). Thanks again to 96edwy, great video tutorial.

dude you are awesome - your video tutorials are excellant very detailed and clear you dont miss anything out helped me flash hd2 for the 1st time to xbmod nodo ROM.

any chance you could create a video tutorial how to install xbmod/yukis 'back to the future' ROM then dual boot with android?

[HD2 Windows Phone 7 Development] sta1cs:
I've managed to dual-boot my HD2 with XBmod-Yuki 7720 with a bit of playing around but even though the Unformatted partition for WP7 is some 7.5GB, WP7 says it's 52.84MB total. Strange.

Also I did it by flashing v1 of 7720 and did the 1hr cab update sender, then reset WP7. Didn't even lock the sdcard when it got to 7720.
[HD2 Windows Phone 7 Development] daniel_kiefer:
You can dual boot with v2 now. There a couple of cabs, one of them does the formatting for you. It's very quick and easy.
[HD2 Windows Phone 7 Development] futaris:
Where can I find these cabs?

There in one of the first few posts on the Back to the Future thread.
[HD2 Windows Phone 7 Development] anab:
probably this issue has been responded earlier....

but so many pages to read...and no time..

i have a problem with my sdcard...

in Easeus , the program dont detect my sdcard ...

I've already tried another adapter and others microsd..

and nothing...

tried to boot in windows 7 ( currently on xp)...and same..nothing...

what should i do ? :(
[HD2 Windows Phone 7 Development] soapbox23:
your sd card is locked. you would need to unlock it in a compatible nokia device or try and reflash WP7.

best way to do it is to do the manual flash (may take you a few hours)...flash the back to the future romv2 WITHOUT your sd card in. go all the way up to 7392 (NoDo), then put in your sd card and go to settings => about phone => reset your phone. when it boots back up it should format your sd card correctly then you can continue on to 7403, 7712, then to 7720.
[HD2 Windows Phone 7 Development] anab:

i have here a nokia e71...should do right ?

what other build could i use with this? any recomendation? im not a big fan of cyanogen look, is to tiny icons for me
[HD2 Windows Phone 7 Development] daniel_kiefer:
Any SD build will work as long as the devs have made it able to boot from magldr.
[HD2 Windows Phone 7 Development] Robbie P:
Screen density (icon size etc) can be changed by editing build.prop.

240dpi seems standard, for market etc. Some roms ship with 167dpi and can have problems with certain apps.

There is an app in market with which you can change density until next reboot.

I updated to mango 7720 but for some reason when I try to boot to android it stops, what to do what to do does any one have an idea of what's going on I partition the sd card with 8/16. Does anyone one what to do????
[HD2 Windows Phone 7 Development] Robbie P:
use storageunlock to gain access to SD

Switch off

Go to magldr/ 10 services/ 1 bootsettings/ 3 AD SD DIR/ ANDROID

this sets the directory where to find your android folder and need only be done once

then 2 boot AD SD

you should then be firing on both cylinders!
[HD2 Windows Phone 7 Development] ikando2on2:
still no boot

still no boot did what u told me......!!!!
[HD2 Windows Phone 7 Development] Robbie P:
Ok so I guessed wrong;)

But If you give more information, extrapart size, android rom, what you have tried, what message you are getting, anything that might give people here a clue as to what your problem may be, then we may not need to guess.

Ok, mango 7720 using American a ndroid. Using a 16gs and used n used those steps tha those steps on the site partition 8g. The anroid being and stop I have to pull battery out....????
[HD2 Windows Phone 7 Development] Robbie P:
In the AmeriCan Android installation instructions it refers to "Includes optional rootfs.img that allows to boot build from magldr (!readme! in /sdcard/Android/SDMAGLDR)" which says

-backup your original rootfs.img somewhere safe.

-rename the rootfs.img.sdmagldr to just rootfs.img and

move it to your android install folder ie: /sdcard/Android

-reverse the changes if you remove magldr from your device.

did you do this?
[HD2 Windows Phone 7 Development] ikando2on2:
boot

I did that but no can do I will try downloading another rom
[HD2 Windows Phone 7 Development] `SBR`:
try 3dak MIUI rom it has all the option to boot on Magldr

Hey guys.

Can this guide be applied to Mango?

Thanks in advance :)
[HD2 Windows Phone 7 Development] GreatLorens:
I Have a question as new on that ... can i always just by a smiple way and how

go from wp7 to android any time i like from Mgdlr menu or not ?

or i have to do something again and again every time i want to switch rom ?

and one more question this can be done that way on nand windows 7.5 only?

or to all windows 7.5 roms ?
[HD2 Windows Phone 7 Development] Robbie P:
It depends on which wp7.5 rom you are using.

DFT, HD20wner & pdaimatejam rom is ok to use this.

Yuki xbmod rom you must send extrapartition cab.

Either way, on startup WP7 is booted from magldr automatically.

to boot android you press on/off hardkey, then option 2. boot ad/sd.(after setting up bootsource)

Hope this helps
[HD2 Windows Phone 7 Development] GreatLorens:
Thanks for your repply , it helped me

But unfortunatelly after i have read some more on the forums i realised that using in my case the Xboxmod_yuki rom i have to reset the phone after the partition cab ...so i dont like to start all over again the windows device ....its borring at windows 7 to reset it's planty of apps...that must be re-installed ... so i will pass till i buy my next Original Windows phone then i will try androin on HD2

I don't have a problem with mango rom on my phone now...except if i will find plenty of time to waste so ...i will do ti all over again.

thank you anyway and everybody in these forums that repply to stupid(for the most) questins..

Go back to WM 6.5

First of all, thnx for the tutorial! All works great!

It's just that I'm not to happy with WP 7... I like WM 6.5 better...

Unfortunately I have no idea how to flash back to WM 6.5. I allready tried it the "normal" way, but my phone with WP 7 won't connect to ActiveSync...

How do i go back from WP 7 to WM 6.5?

Thnx!
[HD2 Windows Phone 7 Development] cajunflavoredbob:
Go into the bootloader by holding down the volume down button while the device is powering on. Plug in the USB cable to the PC and the device. Flash any WM ROM from the RUU on the PC, or use the SD card method of flashing.
[HD2 Windows Phone 7 Development] Virome:
Thnx! Did this method before, a long time ago...

Works great!

Thnx for the help!
[HD2 Windows Phone 7 Development] judgefargo:
No need for SD adapter.

If any of you are having the problem like me, that when you put your SD card in the pc it asks to reformat to use an the Easus wont see the 2 partitions, just mountsd in the magldr after the resetting wp7 part of the tutorial. you will see both partitions as described this way.

Hope it helps, happy christmas!!
[HD2 Windows Phone 7 Development] Maximenis:
I've been through the thread and another tutorial, but something that wasn't made clear to me was the need to have both the FAT32 and the WP7 partitions made primary partitions. I could boot up to android but the SD card in Android wasn't available until I made the WP7 partition primary as well. Just FYI in case someone runs across this problem (I originally thought only the FAT32 partition needed to be primary).
[HD2 Windows Phone 7 Development] mutil:
i was just exploring information about this situation. thanks for information. i'll try this right now:)

If I could get an answer ASAP i would appreciate it!! Thanks in advance!!
[HD2 Windows Phone 7 Development] d3m0n1:
That depends on the way you are trying to dual boot wp7 and android.

If you use another sd card for android, and remember not to boot wp7 when the other sd is in your phone (the one with the Android build), then you are fine. If you are trying to boot android from the same sd as wp7 then you will loose your wp7 data, because one of the requirements of setting up the sd card for dual boot is to hard reset wp7.

[HD2 Windows Phone 7 Development] PrometheusUnbound:
Thanks!! I appreciate the info. Dang, looks like I'll have to back up everything and, start from scratch, oh well can't have everything. I also saw on another thread, can't remember where that dual boot gets ride of green tint on the wp7 camera, has that been confirmed? or was that just some lucky ramdom guy, with dual boot? Incidentaly is anyone working on the green tint fix?? I think I'm asking questions that might not be for this paticular thread, but if you could point me in the right direction I will appreciate it. Once again thanks for the info, now I know what to do.
[HD2 Windows Phone 7 Development] youngdaddytc:
couple questions...

SOLVED - never mind, I figured it out after some reading. just had to make both partitions primary. now they both have 7.5 gb's available.

"Ok so I followed your tutorial, everything worked like it was supposed to. I have a couple questions though.

'My sd card is formatted with 2 partitions. 7.5 GB for windows and 7.5 for android. But i find that when booting android, i can't take advantage of that extra space. Im only allowed 1 gb internal and no sd card card shows up. Is there a way to extend it so that instead of the 1 gig i get, i can instead have 7.5?

'Second question. If this isn't possible, can we fool android into believing the extra space is a mounted sd card?

'Right now i have unused wasted space and that's no good. I also wonder...for apps that require that sd card space will they work? Namely copilot...?

'Lastly, i have researched that it's possible to enlarge the space available, but not to the size i want. I'm hoping there is an alternative. Tnx in advance."

You need to make your android and wp7 partitions to be primary. You can do this with Minitool partition manager (or wizard). Search google for the app, it's free for personal use.

really? i though of doing it this way and it was the first thing i tried but my computer didnt recognise it, i assumed it was because MAGLDR cant interpret the strange wp7 partition in usb mass storage mode, but maybe i was wrong

there is a report that DFT team are working on winmo 6.5 for SD cards to probably yes, i wud image it wud b the same proccess as wp7 and android but you would make an extra partition on your sd and put winmo on that
[HD2 Windows Phone 7 Development] 96edwy:
im not 100% sure but i dont think so, wp7 does some formatting on your sd card when you install it from fresh so i think it might overwrite the partitions that you create to put android on your sd card

[HD2 Windows Phone 7 Development] 96edwy:
yeh just take it out and plug it into your reader, put another build on it the way i did in the video, just copy the files across, you will need to make sure that the build you put on is dual boot compatable tho, by this i mean you will need to have an edited rootfs file. check your roms thread to see if anyone has done it for you or if the dev has included it in the rom. if not their is a tutorial on here on how to change the sd build to be MAGLDR compatable
