boot into magldr and it should be under services, boot settings, boot source, then boot android from SD
[HD2 Windows Phone 7 Development] fatalus:
Is there some way we can have larger android partitions than Wp7 ones?
[HD2 Windows Phone 7 Development] HC4Life:
Impressive. I followed the tutorial step by step and it works great.

Good work!

Thanx ;)
[HD2 Windows Phone 7 Development] 96edwy:
yes there is

HERE IS A WORK AROUND SO THAT THE ANDROID PARTITION CAN BE THE LARGEST (SUBMITTED BY mr_brew)

When you create the Android partition instead of moving it to the end of the SD card move it to the front. After you go into WP7 the unallocated space will be moved under the 200mb fat partition and you will be able to resize it. "Works like a charm" That is the way that I gave myself 7gb WP7 and 9gb Android Desire HD.

Cheers mate great tut. P.S. I did it all through mgldr (mass storage) ver 1.3 .
[HD2 Windows Phone 7 Development] 96edwy:
Cant believe this :@ i was pissing around with my sd card adapter for ages, the write lock was messing up and write protecting my card, tried many fixes, taping it etc etc eventually tried borrowed a card reader from a friend that didnt require an adapter it just had a micro sd slot. n now people are saying they can do it through MAGLDR, that was the first thing i tried and it didnt work! FML

PS also the tuts i read on this said you either need 2 SD cards or 1 sd card with a reader, there was no mention anywhere of using MAGLDR mass storage so i thought, why would they not mention it as its the easiest way, it must be because its not possible
[HD2 Windows Phone 7 Development] DjEyeU:
Great work!......both WP7 and Android work.....but one small problem....after i setting up my WP7 and all and leave my phone charging and my cell start to retart itself automatically. it did like 2 time and i have to setup WP7 again. what cost that? and i think i need a bigger sd card...when i try to installed HTC HUB or any APPS and it said that i don't have enough space. right now i am using 14gb sd splite between WP7 and Android. suggestion please! thanks u...
[HD2 Windows Phone 7 Development] zarathustrax:
Magldr will work with mass storage mode ok sometimes, but I wouldn't trust it right now until cotulla fixes it. It's known to corrupt files or mess up a few bytes of a file when transferring. If you have nothing else, try using it, but if you have problems, that could be the cause. Cotulla tried fixing it in 1.13, but it still has problems, thats why its listed as experimental in the magldr thread. If you have a card reader, you're better off using that.

Sounds like an incompatible sd card if it's reseting automatically and causing you to set up again. After it reboots and sets up again, it's probably not using the memory card anymore, so that's why you're running out of space. How much memory does it list you as having in wp7? If it's not reading the sd card, it will probably say around 15mb.

Also to anyone having trouble getting any sd android builds working with magldr... I have edited and gotten most sd builds from december til now working great with magldr... I got like 13 out of 15 builds I've tried working well... so if anyone is looking for a specific build, pm me with what build you want and I will be glad to share copies of my edited builds if I have the one you want working.

SD Android builds that boot from MAGLDR : http://xdaforums.com/showthread.php?t=913964 (maybe link in OP?)

zarathu, thank you for the work you have done in that thread.

i have spent the last 24 hours fervently testing SD builds that are compatible with WP7.. i think i have found the winning combination of builds here guys.

i am on a tmous Leo and i have been using the 16gb class 2 Sandisk since i got the thing, hspl and on radio 2.15.x. i have tried 2 WP7 ROMs and i am using the Moon Light ROM now. i went over to NANDroid when MAGLDR was released and i tested over 20 builds there.

i can safely say that the SD version of Nexus HD2 Froyo (tytung) is by far the fastest build of android i have tried.. i tried every other build in the MAGLDR boot thread, and tytungs was by far the fastest build. DSs SUPERRams kept locking up and they would get laggy as hell after a couple minutes, and all the Desire HD ones had the laggy bloat of Sense, but the Nexus HD2 Froyo rom runs so damn smooth its not even funny.

android is seriously as responsive as WP7 when running this combo, and i am just amazed at how fast both OSs are running. just thought i'd share with you guys my experience so far.

Moon Light WP7 + SD Nexus HD2 Froyo = MASSIVE WIN
[HD2 Windows Phone 7 Development] zarathustrax:
If there's any other build you want, like I said earlier... pm me. I have many more working than is posted in that thread.... JDMS, HD2One, SkinnyEvo2.1, both of Motoman's Evo based builds, cedesmith's desireHD2, TopiaHD, etc... Personally I find JDMS and HD2One my favorites, both running fast and with low power consumption.
[HD2 Windows Phone 7 Development] Penzi:
unfortunately, i seem to be very stupid as i am not even able to move past the partition creating point of the tutorial. first i loaded wm7 on my hd2 without any problem. afterwards i did as is explained in the (excellent) tutorial. reset the phone to factory settings, enter magldr, take the sd card (16gb) out and i put it into the card reader of my laptop. first i deleted the 14 gb part and when i wanted to create the new partition (also, new partition was bigger than unallocated space before and i chose unformatted in the dropdown menu) it said some error in the operation and it could not be completed. i already checked to see what i did wrong but unfortunately, i seem to be too stupid to find it out. is there any one here who might be able to tell me what i am doing wrong or what has happened?

thank you guys in advance

cheers

Data loss?

This sounds awesome, but I have two questions:

When messing with the partitions, will I lose all my WP7 apps/settings/music/etc?

More importantly, would I have to activate the phone again?

I just finally got everything set up, and I'm not too keen on doing it all over again.
[HD2 Windows Phone 7 Development] 96edwy:
youll just be missing the apn settings, i have a thread on here about it
[HD2 Windows Phone 7 Development] 96edwy:
yeh youll lose everything because ryt at the start of the video i do a hard reset, also yes you will need to re-activate
[HD2 Windows Phone 7 Development] jsc619:

[HD2 Windows Phone 7 Development] en!gma:
Thanks for the quick reply. :D
[HD2 Windows Phone 7 Development] benjaminries:
Just a note of thanks for the tutorial, and some new info - I managed to get this working using cope's extra linux partition scheme. Basically when resizing the 200MB FAT16 partition in EASEUS and formatting it FAT32 with 32KB clusters, I put it at the start of the card but don't swallow all of the unused space, leaving about 1.5GB in the middle of the card between the FAT32 partition and the "unknown" (WP7) partition.

Then when going into MiniTool to switch the WP7 partition from Logical to Primary, I also create two new primary partitions in the "empty" space in the middle of the card... first an ext3 partition labelled "sd-ext" sized 1024MB, then a linuxswap partition sized 512MB. So my 32GB SanDisk class 4 card is now partitioned as follows:

7GB Primary FAT32 "Android"

1GB Primary ext3 "sd-ext"

512mb Primary linuxswap

20.5GB Primary (unknown)

Not only does WP7 still boot just fine, but Android sees the swap and internal storage partitions too. This is supposed to improve performance; it also provides a method of retaining user-installed apps in Android even when the build is entirely replaced.
[HD2 Windows Phone 7 Development] benjaminries:
Oh and like others on this thread, I'm only able to get Cope's 0204 build working... the 0209 just stays on the initial HTC bootscreen for over an hour before I give up on it.

Wow finally a very good tut, thanks
[HD2 Windows Phone 7 Development] bankarce:
One question if you do not mind.What can I use to backup everything on the Windows Phone 7. You see I got WP7 installed since two weeks ago. I do not want to go thru the hassle of reinstalling everyting from market and resyncing the contacts the smart tiles and everything,

Is there a app for WP7 that can backup everything on the device prior to formatting the SD Card?

Thanks

Help With WinMo7

Im gonna do your tutorial on getting 7 on the HD2 but I think I heard something about not being able to download apps.

Is this correct?
[HD2 Windows Phone 7 Development] 96edwy:
you cant download apps without a activation code which you need to ring microsoft to get one. however thats why there is a jailbreak for it, i have a video on my channel on how to jailbreak your wp7. if you flash one of the custom roms then you wont have to jailbreak as they come already done
[HD2 Windows Phone 7 Development] imthewillieg:
Awsome. I couldnt be happier with the windows7 side of this. Glad to get ride of that cluster F@*& 6.5. Ive got 7 activated and fully functional! Cant thank you enogh.:D

I havent been able to get any android builds to run. I keep getting a Zimage load error. However I LOVE windows 7 so far. And am not dissapointed the slightest.

Also i could not partion my SD card corectly. I found a way though. use 2 SD cards (one half the size of the other). I Use an 8GB and a 16GB. Start windows 7 with your 8GB card in your phone. Partion your 16GB card with 8GB at FAT32 (for Android ). Partion the rest as unallocated. Then copy your 8GB unformatted partion to your 16GB card. Put the 16G card in your phone for use.

I quess my question was not interesting enough the first time.

I did the tutorial and now i am able to dual boot WP7 and android. Well, i was able to. The first two times to play in both OS's. This morning the phone woke up in android with full battery charged and everything was ok. Then I decided to go inside WP7 to check on some pictures I took with it yesterday.

The WP7 booted up properly and then in the middle of going thru the pictures it crashed to MAGLRD and then the Android started to boot. And it is still booting. Tried to restart the device by removing the battery, but to no avail, the phone hangs on the green HTC logo.

I am using all the correct radios and kernels.

What could be the cause of this?

Hey guys.

I have a problem with flashing radio, magldr..etc.

Everytime i start RomUpdateUtility it comes to the loading screen but it stays like that for a long time.

I have no idea why...some weeks ago I could flash a radio within 30 seconds..

And when I flash WM7 with MAGLDR V1.10 it comes to magldr ..."Booting WM" and then it goes to the boot menu again ..

No idea why.
[HD2 Windows Phone 7 Development] HD2kty.:

WM7..i flashed it its not starting ...

Now I rebooted it and stuck at the htc bootscreen..nothing happens :(

How can I flash WM 6.5 or something on it ??

thanks for the job realy nice

i have a question! I ve alrady installed win7 on my HD2 with a lot of applications

so if i want to partition the sd card all app installed from win 7 will be deleeted !!!

so how to save sd before partition ?? when i put the sd card in may reader, windows 7 do not recognise files created by winphone7 !!!!

any idea ?
[HD2 Windows Phone 7 Development] futureshock:
i've a small problem maybe someone can help...

i had an working dualboot with phone 7 and my miui android port...

yesterday i had to reflash wph7 because i relocked it and didn had any change to reunlock...

after that i recognized that it usesed the full 16gb SD Card... (i had backuped my android folder before because i thought this will happen..)

than gooing trough the process of getting dualboot to work...

now i copied back my android folders and when i boot up android from sd, android didn't recognize the sd card as inserted!!

i can't start any app thats installed on sd... no idea what i should do now.. have tried to reformat, and also to completly delete and recreate the fat32 partion... no luck... android didnt says sd is inserted!!! :(

edit:

i'm pretty sure now something with the partition layout has to be the problem.. because when i copy the files to my 8gb sd card. everything is working... android sees the sd card... ;( wtf...
[HD2 Windows Phone 7 Development] HQRaja:
I followed your guide to the point where I needed to insert the SD card into a card reader and connect it to the PC. I am using an 8GB SD card and now when I open EASEUS Partition Master (or any other partition tool for that matter including Windows Disk Management and Minitool Partition Wizard), it does not show me any 200MB partition. All I see is 1 GB unallocated space and that's about it - nothing else. The remaining 7 GB isn't even shown as unallocated. Here is a screenshot to elaborate things further:

View attachment 517583

Any help with restoring the SD card to the way it was and reclaiming the lost space will be greatly appreciated. Also, any help on how to avoid this issue when I try again will also be welcome. Thanks in advance.
[HD2 Windows Phone 7 Development] futureshock:
wph7 did not formated his filestructure on it...

try again...

maybe you have an non working sd card..
[HD2 Windows Phone 7 Development] HQRaja:
The card was definitely working perfectly on my HD2 with Android before I attempted this. It sure is non-working now though. I tried the WP7 procedure all over again, but to no avail. Now even if I can mange restoring it without being able to use it with Windows Phone 7, I'll be fine but I have tried all the tools I could find including EASEUS Partition Master, MiniTool Partition Wizard, DriveRestore Professional, SDFormatter and even Hard Disk Low Level Format Tool, but to no avail.

Has anyone had a problem like this and did they sort it out?
[HD2 Windows Phone 7 Development] afridiaziz:
I have the same problem but my card is not seen by the partition manager at all and hence i am unable to follow the procedure to have android as well as wp7. I will try with another wp7 rather then this one though and see. any other suggestions?

Question... So I got everything working, JDMS is working great w/WP7 as well, besides one thing. It is not recognizing that I have an sd card in JDMS so I can't really download anything for android or save anything. Any suggestions?
[HD2 Windows Phone 7 Development] afridiaziz:
I tried with XbMOD ROM WP7 and with other cards....same isuue and now even trying to flash ROM 6.5 via bootloader failed as well.. Can anyone help please. I think i will go back to 6.5 and Android...Better combination then wp7 untill my issue is resolved. thanks
[HD2 Windows Phone 7 Development] zarathustrax:
Sounds like you forgot to change the wp7 partition from logical to primary. You can use minitool partition magic for this... i have attached it to many of my posts in other sd partitioning thread in the android sd dev section, if you can't find it, pm me and I'll send it to you.
[HD2 Windows Phone 7 Development] vagelisv:
same here too... no sd card on easeus... tried partition magic and has only only a primary not formatted partition... what should I do ?
[HD2 Windows Phone 7 Development] axw820:
Thanks for the great guide! I've got everything working fine, both OSes boot and function ok, apart from WP7 doesn't seem to have any space for anything. I checked the about part after finishing the process and it says I only have 15mb of total storage space, it should be about 3.5gb. It won't download anything or even receive texts due to the lack of space. any ideas?

thanks.

EDIT: I've taken the sd card out and it's displaying the same - Total storage: 15.73MB. So it's not recognising the SD card.
[HD2 Windows Phone 7 Development] masteroe12:
thanks for the tut, it works great !!!

When i want to install a new Windows Phone 7 Image ,

do i have to do the same procedure again ????

Am i able to stay with my Android Build (on the first partition) without installing it again from beginning? I think Windows Phone 7 will format the whole memorycard during installing or?

My Android Version ([DL Desire Series][DL Init v3.5][Nand/SD/MAGLAR) works so well (incredible battery performance ;)) that i do not want to install it again with all installed apps....:eek:

Going to HSPL instead of MAGLDR

I have installed WP7 on my HD2 and trying to install Android on the SD card.

My problem is that after I reset the phone in WP7 and restart, I keep holding the power button but I end in the tri-color SPL screen not the MAGLDR screen, why is that happening?
[HD2 Windows Phone 7 Development] htcluver87:
Followed all the steps, partitioned fine...WP7 boots and I am able to see my empty partion on Android side of card. Copied all files to sd, changed file name and copied both files to replace. Placed all files in android folder. Rebooted device into MAGLDR and tried boot ad sd...it hangs at sd kernal open failed.

Any suggestions?
[HD2 Windows Phone 7 Development] zarathustrax:
Are you using a magldr compatible build or editing the build to work with magldr? I have links to some of my edited magldr compatible builds in post 2 of this thread...http://xdaforums.com/showthread.php?t=945565

I figured it out. At the point where he first trys to boot to sd it fails, then you have to go into the setting menu and do the rest. I got it to boot at the htc load screen now. My fault for not following all the instructions.
[HD2 Windows Phone 7 Development] crayola555:
Ok here's a question I got in my head for a while.

Since wp7 formats your sd card on every first boot, if I was dual booting wp7 and android then decide to flash a new wp7 rom, would my sd card get formatted by the rom and I have to do this android partitioning again?
[HD2 Windows Phone 7 Development] D-r-e-a-m-e-r:
Thanks for the detailed information. Both the OS work like a charm however I have a similar issue as under:

- In WP7 my 8GB card (4Gb used for WP7) only shows 15.30 MB space soon after reboot but it resets to 3.49 GB when I set all user data.

- Soon after reboot WP7, all user data is erased and again the memory is back to 15.30 MB

My WP7 alone works very good with this Micro SD card hence no SD compatiability issues.

Any help experts...

Thanks :)

Struggling with WP7. Used all the methods for partitioning but still in vain....

The WP7 user data deletes with the reboot.
