Tutorial: Dual Boot WP7 and Android + Magldr Builds + More To Come...

Thread update.​
I am now working on providing tutorials for the following.
One card method - I am looking to improve this if I can.
Two card method - This is for micro SD cards over 8gb. There seems to be issues when using 16gb card with the one card method so I am now extensively looking into this to provide tutorial to make larger Android partitions than WP7 if you wanted (As WP7 takes the largest partition with the one card method)
Android SD Magldr Builds - More support and more intuitive tutorials for setting up all known SD Magldr Builds.
I am also looking into alternative ways to the above. I have lots of ideas and theories to improve speed, functionality, setup and configuring you PC/Laptop for convenience to performing the 2 card method, not just for now but for when you do this again in the future. For example, you may wish to install the latest WP7 ROM. The tools are already included in Windows operating systems later than XP. I am now experimenting this and so far, it looks good.
If there are any requests on what else I should provide support or tutorials for, the please feel free to leave you comments either by private message or through this thread.
Please be patient with me as I am trying out the above to make it as clear and hassle free as possible. I have learned a lot from Xda and this is my way of giving back and helping others.

In this thread I have put together a tutorial on how to dual boot WP7 and Android using the one card method. To use Android, the build must be one that has been adapted to work via Magldr. Builds which has been kindly adapted by zarathustrax are on Post 2 so please show your thanks to him for taking time to convert them for us to use.
This tutorial presumes you already know your way around Magldr and know what buttons to press to select etc. If you need any help then let me know. I will help the best I can but cant always promise to be online. The tutorial recommends you use a SD card reader instead of Mass Storage in Magldr as Mass Storage is not always reliable.
1/ Download a WP7 and Android Build (Maglrd Build) you want to use.
2/ Run DWI.exe to install WP7 to your phone.
3/ Go through the setup and once it tells you that you have a new SMS which is welcoming you to WP7 go to Settings - About - Reset Your Phone and once phone restarts hold power to enter into Magldr.
4/ Remove SD card and insert it into the computer.
5/ I used Minitools Partition Wizard which you can get HERE, the Home version is free. Start the program and you will see two partitions on your SD card. Right click and delete the largest partition, this will leave you with Unallocated partition.
6/ Now right click the Unallocated partition and select Create. Leave 'Create As' as Logical and 'File System' as Unformatted. Under 'Size and Location', slide your Unallocated space to the right to roughly half the size of your SD card so the blank grey area is on the left. Click OK.
7/ Now click on Apply (The tick) and when it comes up saying Successful (This may take a while), remove your SD card and put it back into your phone and shut down Partition Manager.
8/ Boot up WP7 and go through the setup again. Once the message beeps again to say welcome to WP7, go to Settings - About and look at the 'Total Storage' and 'Available Storage'. These values should now be roughly the same.
9/ Hold Power button to restart and hold Power to enter into Magldr. Remove SD card and put it back in your card reader. Open Partition Wizard again, right click on the 200MB Other partition and select Delete. Right click on the new Unallocated partition and select Create. The File System should be Fat32 and set as Primary. Click Ok and Apply (The tick).
10/ When all the changes has been applied click OK and right click on the Other partition and select Modify and then Set Partition As Primary. This is important to run Android as well as WP7. If Partition were still Logical then once Android Build was loaded it would not recognise anything off your memory card . Put the SD card back into your phone and boot WP7 and exit Partition Manager.
11/ In WP7, go to Settings - About and double check the Total Storage and Available Storage to see if they are the same as before, they should be except the one should now be 200mb larger.
12/ Power off and insert SD card back into your card reader.
13/ This time start Computer or My Computer depending what version of Windows you are running. Move the Android Magldr folder to your SD card and read the instructions to set boot settings in Magldr. This time I will Boot MarkinXHDExtraClean Magldr Build but DL Desire Magldr build worked for me just as good as Nand. You can also use one of the builds in Post 2.
14/ Once Android folder has been copied, remove the SD card and put it back into your phone. When in Magldr, press the volume buttons up and down until you get to Services - BootSettings - AD SD Dir. For MarkinuXHDExtraClean Build the zImage and initrd.gz are on the main directory of the SD card so select <->. Always read the chefs installation instructions.
15/ You should now be in the main Magldr menu. Press vol buttons and select Boot AD SD.
Congratulations.......you know have WP7 and Android dual booting on your device. If this tutorial helped you, then please hit the Thanks button.

I'm beginning to turn this post into a collection of the builds that I've edited to work with magldr to dualboot with wp7. I am keeping these builds in my dropbox for quick and easy download... just right click the download link and select "save link as". I am just including the entire build for most of these for convenience, because some of the builds needed the init.rc file edited after the build was booted up once, as there were updates and files that get installed on first boot and the init.rc file was changed back to normal... so all the builds here have any updates or files in a root folder already installed, so they are all ready to go... just unrar and copy build folder to root of sd card, and be sure to tell magldr which folder to boot android from. Most builds include a new 1gb data.img or they create one on first boot, in which case it may take 5-10min.
All credit for the builds go to the chefs of each build... all I did was modify the init.rc file so it could be successfully booted with magldr. If any chef does not want me posting a download link of your build here, and would prefer I just post the edited files or not post anything about your build at all, please pm me and I will remove the link immediately. I am not trying to take credit for any of these builds... I am just trying to make it easier for people to install and run.
So, here's the builds:

Darkstone SuperRam Build and Sense RAM build Edited by LeTama This is not edited by me, but by Letama. I am putting links here for easy download for convenience and so all the edited builds can be collected in this one post. These builds will take a couple reboots sometimes before they fully boot up, but once you get them fully booted and going, they should boot up everytime afterwards.

Remember, to download, just right click link and select save link as.
I have more edited, and will be adding more to this post as I get time to organize the post and builds and make space in my dropbox. If you have requests on what builds I should add next, or have any questions, feel free to pm me. I have gotten most builds I have tried working well booting from SD with MAGLDR. ENJOY!
ALSO.... I've had a few problems recently with my computer corrupting some of my edited rootfs.img's... I think all of the one's listed so far are ok, but if anyone has a problem with any of them running, please pm me and let me know so I can fix it. I'm re-editing some more builds soon, so I will add the rest of the builds I've got running to this post soon.

Very nice tutorial and easy to follow. I had problems before when I tried it and almost gave up.
Thanks

I used the original posted guide to get mine working, albeit I struggled initially due to not reading it properly. If your new guide helps more persons to get WP7 and Android dual booting then that is great BTW I am using this CM7 Gingerbread build on my android partition and it works great, just need to follow the additional instructions in the install folder for getting it to boot via MAGLDR http://forum.xda-developers.com/showthread.php?t=898831

Thanks for your feedback and I have to agree that with the original tutorial, I did struggle with it myself. Also it shows a few ways to do it. The one is a very long process copying one partition to another which dont apply for most people.
I posted this to try and make it clearer and easier to follow. I also focused on using only application for partition management where the original told you to use two.
Thanks for letting us know about the CM7 Gingerbread build. Most builds can be modified in a Linux Distro where just editing one line will make the SD build boot in Magldr.

Thanks so much for the guide and the Android Rom recommendation.
I got a question...
I got Android successfully booted, however under Android environment, it says no SD card is present. I'm using the DL Desire Magldr build.
Do I need to make another partition???
Any help is appreciated
Thanks!

out of curiousity,
Can the both of them share the same set of media files? or do you need two sets of it, one for the android partition, one for the WP7 partition.

You forgot to change the wp7 partition from logical to primary. That will solve that.

No, they can't share files. WP7 only reads it's partition and android only reads it's partition.
That's why I like to use dropbox with both of them. I can keep music or files in my dropbox and access them easily from both OS's. There's several dropbox apps for both wp7 and android. It also makes it easy to transfer files to my phone without having to hook it up to the computer or take the card out or deal with zune. Use my referral link below in my signature to get an extra 250mb added to the initial 2gb you get for free when you sign up and install the dropbox app to a computer.

The answer to the question and the how to is in the tutorial above. I have copied it for you for your convenience.
Make sure you have switched off your phone because you will loose info if you just extract the SD card in WP7, insert SD card into a card reader on your PC. In Partition Manager.....
'Right click on the Other partition and select Modify and then Set Partition As Primary. This is important to run Android as well as WP7. If Partition were still Logical then once Android Build was loaded it would not recognise anything off your memory card.'

Thank you I'll be trying it soon

No problem... I was very active in the other dualboot thread, too. You did a good job writing this tutorial up, so hopefully there won't be too many people confused, but I'll be around to help answer peoples questions, too. I figure once a thread is public, it's up to everyone who knows to help everyone out who's having problems... that's what this community is about... plus the more people that get involved in problem solving, the more we find easier and better ways of doing things. It was actually hyellow and me that figured out that you need to change the partition from logical to primary when I was having the problem of not being able to mount the card in android. It was fun watching and helping the method that you have posted evolve over several days and get easier and quicker to do.
Also, I was thinking that I might collect all my edited SD builds (I've got almost every build working) in to my dropbox and post the links to them in the second post to make it easier for people following this tutorial to grab a build that's already edited to work with magldr. What do you think?

htc hd2 overheats when dual boots
I have dual booted my HD2 using an 8 GB and 16 GB SD card. I got everything up and running and the bottom one third of the HD2 gets hot and freezes or reboots every time . When I placed one rom on the device, the device runs normally. Can anyone advise what might be the problem and the solution.

Can you provide a bit more clarity to your problem.
Does this happen with both the 8gb and 16gb cards? Also what build are you using when your phone gets hot and restarts or freezes?
I find it strange that it is fine when you are using either Android or WP7 without dual boot as you are using only one build at a time when dual booting. You are only gaining access to different partitions on your card, pretty much the same as you would if you have an EXT2/3/4 partition for data saving in Android. Do you still have the same problem if you partition you SD card for a EXT2/3/4 for data saving?
From what you have said the only possible reason is somehow your phone might have a problem dealing with partitions because in theory dual booting runs either one or another and shouldnt be different if you were using only Android or WP7.
Using Minitool's Partition Manager, you might also want to try formatting the Fat32 partition by right clicking on Fat32 partition, click on Format and choosing the cluster size to 32. Save these changes and try again.
The solution could be setting up Android to work properly. In DL Desire's build, there are quite a few options as to how you save your data. You have the save to Data.Img file which must be placed inside the directory for the build, and without going through every type there is also save to EXT2/3/4. You must alter the values in the Config.txt file for the build to know where to save data. Double check you have setup the Config.txt file correctly as you could be telling the build to save to EXT2/3/4 when there is not one. I dont know but it could affect the WP7 partition so it corrupts it and causes the above mentioned problems. Always read the chefs installation notes. Try installing MarkinXHD Extra Clean Magldr Build instead of DL Desire just to make sure.
Can anyone else throw any solutions to this problem?

I completely agree with the community sharing knowledge and that was one of the main reasons for me posting this tutorial. I am a strong believer in if you give a man a fish, then you have provided one dinner but if you teach that man to fish, then he has a lifetime worth of meals.
It would be very generous for you to share the builds you have converted to boot into Magldr as it would give people more options to what build they can choose to dual boot WP7 with. As a matter of fact, being certified in Microsoft, I was looking into doing this myself and was the next mission for me. I have limited Linux use but I am starting to sink my teeth into it and become fluent.

I post a video here if you like to follow by visualization

Hey which would be the best way to do this activate my phone when i get it then flash, or flash and activate the phone service after i install the Os's.

What do you mean by activate? Do you mean get your activation code? If so, get it anytime... you will need the activation code to use live services in wp7 anytime you flash a new wp7 rom. If you mean activate your cell phone service, that can be done at any time, also.

Thank you for the YouTube link to the same process as described in this tutorial.
I have watched the video and it does not mention that you have to change the Unfomatted partition from Logical to Primary. This is essential if you want to use the camera and to gain access to other files such as music from you SD card. Also in the video it is being demonstrated in Easeus Partition Manager. This is a good program but with it you cant change the Unformatted partition from Logical to Primary. This is the main reason I chose to use Minitool Partition Wizard. With this program everything can be done.

You really should download the HD2 NAND Toolkit. You can use the toolkit to flash HSPL, MAGLDR, or clk to your HD2. It has all of these included in the download for the Toolkit. You can also use it to flash an .nbh file to your HD2. This means you can flash Splashscreens and Windows Mobile ROMs with the Toolkit also.
Go to this thread to learn how to dual boot Windows Phone 7.5 and Android. But just so you know Android can only be run from SD card when you have WP 7.5 installed in NAND. You can not however dual boot Android from NAND and WP 7.5from SD card as WP uses your SD card as internal memory.
Last of all for your on good please read the guide in my signature so you can hopefully educate yourself about exactly what the MAGLDR is and what it's function is. Plus it is a load more of info I think would very much help you to read.

The first thread you linked is a tool used to install Android to NAND widget means Android boots from internal memory. So unless you want to just use Android on your HD2 this is not the guide for you right now.
The second thread you linked is to a SD card buildvthat uses Super RAM which means that part of the main Android system boots into RAM on start up widget makes the build run faster. If this is what you want to use for your Android you just need to download it and extract the contents of the .zip file to the root of your SD card and then either use the file explorer to touch on CLRCAD and then HARET, or you can install a dual boot app for Windows Mobile that you can use to boot your Android from SD card.

I just want to correct a very very wrong statement, WP7.5 is very well supported. The HD2 is often better supported by the dev community than official WP devices, infact the HD2 got Tango before any other WP phone. Also with WP7.5 on NAND you can dual boot so you can have Android and WP7.5, you can't do that the other way around. I would suggest dual booting HD2Owners ROM found HERE along with AmericanAndroid on the SD found HERE. These two are both realy stable and well supported.

Ok let me see if I can walk you through this some. First download the 02.04.12 HD2O© ROM, the AmeriCanAndroid AOSP HD2 SD card build, the Leo_RADIO_2.15.50.14, the EASEUS ALL-IN-ONE Partition Manager Software mentioned in the guide I linked, and if you do not already have it download the HD2 NAND Toolkit. You will also need to download and install Active Sync or Windows Mobile Device Center (these programs have the USB drivers you will need) depending on what version of Windows you have, you will just have to google for a download as I do not know what version of windows you have, I suggest you put both the WP7 ROM, the Android SD card build, and the 2.15.50.14 Radio in a folder that you can easily remember were they are on your computer. Also go ahead and install both the HD2 Toolkit and the partitioning software on your computer.
Now to make sure you do not have any problems with your SD card I recommend you do a full re-format of your SD card. You will need a USB card reader and a Micro SD card adapter.I linked them just so you will have a visual reference of what you need, but those are the ones I have and they work great. Aslo if your computer has a card reader you like mine does you just need a Micro SD card adapter. Now back to re-formatting your SD card.
Place your SD card in the Micro SD card adapter, then place the Micro SD card adapter in the USB card reader (or the USB card reader on your computer), and then plug the USB card reader into one of the USB ports on your computer. Let your computer install the drivers and go to the windows start menu and click on Computer or My computer depending on which version of Windows you are using. You should see the SD card as a removable drive. Right click the drive and select copy and then create a folder to paste the data that is on the SD card already so you will have a backup. Now right click on the drive again and select format, when the format window pops up make sure to uncheck the the box beside Quick Format and also make sure it says FAT32 under File System. Click Start and then click Ok on the warning window that pops up. Then set back and relax until the card is done being formatted.
Now you need to make sure you have at least 50% or more battery, but I suggest you have a full charge before you start just to be safe. Once you have the proper battery level you need to boot your HD2 into the bootloader by holding the volume down button down while you power on your HD2. When you see the multicolor boot connect it via USB and wait until you see the Serial in the white bar of the bootloader change to USB. Now open the folder with the 2.15.50.14 Radio in it and extract the files from the .rar file, you will need Win RAR to do this. Once you have the files extracted click on the CustomRUU.exe file and follow all of the on screen instructions. Once the RUU is done you will have the 2.15.50.14 Radio installed on your HD2.
Next you need to boot your HD2 back into the bootloader and connect it to your computer via USB again. Open the HD2NAND Toolkit and click on the Install HSPL button under Main Tools. Follow the on screen instructions and when it is done you will have HSPL 2.08 installed on your HD2. Now go back to the HD2 NAND Toolkit and click on the Insatall MAGLDR button under Main Tools. Follow the on screen instructions and when it is done you will have MAGLDR 1.13 installed on your HD2.
Now that you have MAGLDR installed on your HD2 it should only boot up to the MAGLDR 1.13 main menu. Go to option number 5 USB Flasher and then find the HD2O ROM file you downloaded and extract the files drom it. Once the files are extracted click on the DWI.exe and follow the on screen commands. When it is done you will have Windows Phone 7 on your HD2.
Now you need to follow the part of the guide you linked that I have quoted below. I left the link to the video of the method that I have quoted so watch it as it is a very good video. Oh and in case you do not notice it in the video, you need to hold down the power button while your HD2 is booting to boot to the MAGLDR main menu. And the video will show you how to get the Android build to boot on your HD2.

THIRD METHOD - USING A SINGLE SD CARD - HERE IS ANOTHER ALTERNATE METHOD PROPOSED BY XDA MEMBER HYELLOW (UPDATED)
1. Put your sd card inside the hd2 and power on.
2. Go to about screen, in settings, and reset your device. Let it reset and boot to WP7 again. While booting to WP7, it'll create the partitions it needs, so this is important. After you have gone through the setup wizard, go to about screen and reset your device again.
3. When it has booted into magldr screen, remove the sd card and insert into pc. (make sure that magldr is shown and stays there at bootup, otherwise it'll boot straight into wp7 without sd card and that is not what we want.
4. You'll see two partitions. A whopping 200mb of fat16 partition and the other is unformatted. Now right click on the unformatted partition and click delete. After that, click apply. Now you have unallocated space. Right click on the unallocated space and select create. Set parameters to logical and unformatted and size the partition. This will be your WP7 partition, so decide how much you want to allocate to it, this is permanent, no changes afterwards can be made. Also, make sure you move it to the end of the sd card in the same 'create' window. Hit apply. IMPORTANT When using this method make sure that the wp7 "unformatted partition" is larger than the Android partition otherwise the wp7 "unformatted partition" will move in 2nd place and you will not be able to resize the fat 16 / android partition.
5. Sit back and take a break.
break.
6. You now have a green fat16 partition to the left, some unallocated grey portion in the middle and your WP7 partition in modern turqoise colour on the far right. Agreed? Now remove the sd card from PC and insert in HD2.
7. After you have inserted the sd card, let it boot into WP7. Remember what your last action was when you were still in WP7? Yes, you pressed reset, so the device actually thinks he is still resetting the device. He might do it too, but just go through the setup wizard again.
8. Go to about screen and verify your storage. Don't look strange if when the storage has a different of about 1Gb, this is swallowed by WP7 for system stuff etc. Are you happy with the progress so far? Then power down your device and remove the sd card. Allow the HD2 to fully powered down as sometimes the screen is pitch black, but the device is still turning off.
9. Insert the sd card in pc and, using EASUS right click on the green fat 16 partition and select resize/move. Now fill up the rest of the unallocated space and hit apply. This is your android partition.
10. Format the sd android partition (not the whole sd card!) using EASUS to FAT32 using 32 or 64 kb cluster size and put an android build onto it and test.
11. IMPORTANT You need to convert the wp7 unformatted partition to primary for the sd android to see the sd card Use minitool partition wizard to do this. Right click on your WP7 unformatted partition and select modify and then click on set as primary and hit apply. Here is the link for minitool: http://forum.xda-developers.com/showpost.php?p=10887494&postcount=372

Hope this is detailed enough for you.

T-Macgnolia did a great job with the walk-through the only thing I would suggest is that you can save yourself a LOT of headache if after you get the HD20 ROM installed use CAB Sender and send one of the partition updates from xboxmod to your phone. This will let you skip all the hard partitioning stuff. The CAB's with various partition sizes can be found HERE. After you send the CAB you will have to go to 'Settings' -> 'about' -> 'reset your phone' -> 'yes' -> 'yes'
From that point on you can finish with installing Android onto the SD card.

Well to be very honest to you I have only flashed four WP7 ROMs to my HD2. So my knowledge of the ends and outs of WP7 on the HD2 is somewhat limited. I do remember reading something about Cab Sender. I think you have your HD2 booted into the WP7 ROM and your HD2 connected via USB to your computer to I se the Cab Sender to transfer cab files to your HD2 and install them also. Maybe XDA Seior Member voluptuary can spread some more light on it for you. But if I remember correctly if what voluptuary is telling to do takes out Step 1 to 11 of the guide I qouted and everything in the video up to here he puts te Android build on the SD card as I think it will. Then I say it sounds like you may want to check it out I am willing to bet it is not complicated to figure out.
Now just on a side note, I do still say it would be a very good idea to still do it te other way even if you try the Cab Sender. It is always a very good idea of how to manually do things. This way you understand a little bit better what you are doing to your device. And remember knowledge is power.

All you would have to do is after you install the HD20 WP7 ROM send one of the partition CAB's I linked to earlier, so say you want a 2GB partition for Android you would send "DEV_EXTRAPART_2G.cab" with CAB Sender and then do a full reset from within WP7. Then let WP7 reboot and you should be all set to power down the phone take the SD card out and copy the 'Android' folder over to the SD card that you would have taken out of the ZIP from the AmericanAndroid thread. You have to be sure to follow the few instuctions in the AmericanAndroid ZIP readme to get it to boot via MAGLDR.
Then to point MAGLDR to the right place to boot Android you need to, while powering the phone on with the loaded up SD card, press and hold the power button to get into the MAGLDR menu then go to '10. Services' -> '1. BootSettings' -> '3. AD SD Dir' and then select the 'Android' folder you just copied over to your SD card.

Well to get a Windows live account you just have to go to live.com and creat a account or just creat one when you go through the set up when you first boot WP7.
But I think what you are asking is how to get live services working. To do this you will have to contact Microsoft. Check out this thread for more details on it. I got my code over live chat on m computer, I told them it was a HTC HD7.

Or you can use skype and call 1-800-642-7676
its microsft Us support number and its toll free so you can call it on skype for free (from anywehre in world) say you have a technical problem and its user related.
then it will connect you to an operator
he/she will ask for your problem, just say u have a HTC HD7 phone and it wants a 25 digit activation code from u.
Then he/she will ask for your phone number, ur operator, ur email, and your name (don't worry they r not gonna spy on u, they just want it for registration, believe me I know ;-P )
then u have to be on hold for 5-10 mins and he/she will read u the activation code
BUT: if you have a poor connection or bad English language skills then the chat method is far better
PS: my opinion as an ORD? it doesn't worth the hassle. I remember after lots of hours spending online and finding the best rom and the best way to change to WP7 and finally activating it... I couldn't make it through the first day on WP7 (even thou I had SD android, the wake up bug really bugged me). then I just flashed to an ICS rom and then it was happily ever after

ok thanks evrey one soo i see a lot of ppl say thet WM7.5 is not thet good...
but i have 2 more qestion:
ace4cia i saw ICS on HD2 in youtube and i saw it is slow not moving fast do you have thet problam ?
and what rom do you advise?
and whan voluptuary says DEV_EXTRAPART_2G.cab its for the sastem only? if i install apps i can do it only on the 2 G or the all SD card

nope, not at all, well it's not like a quadcore phone but it is pretty well for ours, still far better than wp7 though ↖(^▽^)↗

Triple Boot WP7+SD+NativeSD EXT4 @ 1 SD with pictures

Lets try to triple Boot our HD2's with WIN7 + SD + Native SD via Magldr, although I got mine working OK, i'm not entirely sure if this is viable to all. please see last part.
I assume you already have Magldr in your HD2 & its either running WP7 or Andy in NAND or already dual Boots.
If not flash WP7 first in NAND by trying to follow this, WP7 is always in NAND **Anything you have in NAND/ SD will be deleted including CWM**
http://forum.xda-developers.com/showthread.php?p=25781675#post25781675
after that is done the partitioning begins
1 FAT32 Partition
1 EXT4 Partition
1 WP7 Partition
MiniTool Partition Wizard Home Edition (MTPW) using this to do those above.
Be very careful when using the minitool partition as you can accidentally format/ delete your Hard Disk Partition.
i'll be using a 16g card & after flashing WP7 it uses the SD Card as it's own storage using it's own format similar to a RAID setup making it like an Internal storage & what's left is usually 200mb of free space. We need to take back some of that space! :cyclops:
A - Set Magldr > Service > Boot Setting > Always Menu
After you reboot & setup WP7 go to:
••settings > about > reset your phone > YES! > phone re-boots
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
since you set A your still in magldr (don't let it boot to WP7 - yet), remove the card, put it in your PC & run MTPW
you will see something like this
right click on the larger (other)(14.64GB) partition & choose delete
right click on the larger (now unallocated)(14.64GB) partition & choose create partition as "Logical" with "Unformatted" file system.
Slide the tab to the Right leaving a partition slightly larger than 1/2 the SD card that was shown in MTPW
Make sure the "Unallocated Space After : is ZERO 0
after pressing OK something like below will show
Noticed that the "Unformatted" is larger than the "Unallocated" partition
click "Apply" & wait for it to finish.
••Close MTPW > insert SD card to HD2 > Boot WPH
WP7 will continue to boot & do the usual setup stuff
settings > about > to see if the partition has changed.
Turn OFF the phone, take out the SD card & plug it in the PC then run MTPW
the "Unformatted" before now becomes "other" to MTPW which WP7 formatted for it's own use.
right click on the 200MB "other" partition & delete it!
noticed that it combined with the "unallocated" partition & now we have just 2 partitions
right click on the "unallocated" partition
Create As > Primary > FAT32
slide the Tab to the Left for the EXT4 partition, i choose around 2g
when you press OK, an allocated space will be there
right click on the "unallocated" partition
Create As > Primary > EXT4
right click on the "Other" partition
Modify > Set partition as Primary
Now we have 3 Primary Partitions, click Apply & when all is done your ready to go!
copy all the necessary files you need to the SD & see if WP7 boots First, see more on NativeSD+EXT4 below

for partitioning I followed This

Hey man , thanks for tutorial.
I'm using WP7 on my tmous hd2 for long time.
Today i decided to try dual boot native sd and wp7 , and i was searching all day how to do it.
However i accidently did what you wrote there , formatted my main hard disk!
And now trying to recover my partition
I'll try dual boot with that tutorial tomorrow.

YIKES!!!
that's what I was afraid of, that's why I made BIG & Clear, well actually it happened to me once a long long time ago
Anyways there are powerful partition recovery out there, I hope you get it back.

Man this is a pretty good guide, it is also needed to as Native SD is still new to the HD2. I am glad to see you can use 4EXT with the HD2 now as I feel it is truly the best custom recovery out at the current time. I absolutely love the 4EXT recovery Control app, it is the paid version but you can also get the 4EXT Updater app which is free but not all the features are available in it. I am going to suggest this guide for the Portal as it proves you can multiboot OS using Native SD. Thanks for taking time to write this up mengfei.

thanks Man!
I just extended the dual boot of WP+SD to include EXT4 & i hope it's helpful to those that want to have as much option as they can have. I now have like 10 roms just in case one goes bonkers, what a Paranoid hehehe :cyclops:
BTW here's Xylograph's reply to the error I was getting.

I have been away from WP7 for a long time but would like to taste it once again

Hi mengfei, do you expierence poor speed performance on android with triple boot? I installed NexusHD2 rom with nativesd and, I must say, it is painfully slow and barely usable. Even downloading something to the card is slow. I have no speed problem with wp7. I have a transcend 8gb class 6 with this partition layout: 2,5Gb Fat32, 1,5 EXT4, 3gb for wp7. Is there something I can check or I can do to improve my android installation or the speed of sdcard?

@serverless
no problem with my 16g Sandisk Class 10, just flashed JB AOKP's latest & it's buttery smooth.
I had problems with a 4g Sandisk which i think had a problem or is fake even when running normal SD Rom's & my Class 10 16g Transcent is not compatible with WP7 - it wont detect it.
if you can try another Card or reformat the card, give it shot.
HTH

Yes, it is very good. though I now feel that I need to change my SD card. I have an 8 GB Class 2 SD card (the main culprit for slow speed) and now I am thinking to buy a 16/32 GB SD card but confuse with the class. I know Android write data on non-sequential manner but which one would be better? I am thinking of buying either Class 4, 6 and 10 SD card.
Thanks

Because Class 2 and 4 have better random access speed than an Class 6 or Class 10! Class 2 or 4 was the better choice for an OS, Class 6 or 10 was the better choice for big datas like movies or pictures, because they have a cache! This cache (Class 6/10) must always rebuild and this make it very slow for random access.

Then i followed your steps and flashed wp7 and android. Everything is working perfectly in spite of using 16gb class 2 sandisk.
Today i bought a 16gb class 10 sandisk mobile ultra which is specially for android devices (thats what they said) and will flash android again.

I have question regarding the used radio when dual booting wph7 and android (native sd). Currently I use radio 2.15.50.14, as I did with android on NAND. Now I read that in wph7 it's recommended to use radio 5.51T. Is that even possible?
I'm sorry if that's the wrong thread or a stupid question.

@soulforger
good to know you got your files back! :highfive:
let us know how it goes with those cards.
@derschnelle
2.15.50.14 is good for all, once you flash this radio from the start you can leave it alone with WP7 or Andy. One Radio to rule them all :cyclops:

Hi mengfei, do you expierence poor speed performance on android with triple boot? I installed NexusHD2 rom with nativesd and, I must say, it is painfully slow and barely usable. Even downloading something to the card is slow. I have no speed problem with wp7. I have a transcend 8gb class 6 with this partition layout: 2,5Gb Fat32, 1,5 EXT4, 3gb for wp7. Is there something I can check or I can do to improve my android installation or the speed of sdcard?

hi, did you fix the speed problem that you where having? if so what was the problem in the first place? please do let us know. thanks.

Hello mengfei,
Thank you a lot for your excellent tutorial. It's I've been looking for.
Would you Please let me know how to install native SD Android ROM on such prepared SD (WP7 delletes CMR I use to install zip ROMs from SD) or maybe you can address my question to developer who knows ?
Thank you once again and regards,
=======================================
Hello again,
I've read your tutorial again, carefully and came to conclusion that my request is senseless, everything is described. So, I'll try to install WP7 on NAND and AD on nativeSD.
Thanks again,

Hi,
I have followed the tutorial but my nativesdrom (evoHD2v10final) can't find the FAT32 partition. So i can't use the storage.
i have 3 partitions: FAT32 + EXT4 + unformatted( wp7)
Does any has the problem?
Thanks in advance

I am going to get hd2
one of the legendary devices out there

How to dual boot Latest builds of WP7 and Android JB

Hi I was wondering if anyone can guide me through dual booting the latest WP 7.8 build and Android JellyBean v.1.2. I love both but can't seem to dual boot both. It's either one or the other.Thanks in advance.

But that forum doesn't say what to do once you install WP7. Like how to install android JB to dual boot both. I want to dual boot the latest builds for both.

Emm... It says you must do reset of you phone from settings (or hard reset from magldr). Then you should don't let your phone boots (just stay in magldr). Remove your card from phone and put it to PC's card reader. Use MiniTool Partition Wizard to create more partitions (fat32 and ext4). And there you go. Try to boot WP7. If it boots normaly just install Android as NativeSD.
You will be lost any of your data on SD.
I think those tutorial is clearly enough. Hope you can repeat all of this steps.

I too, am finding the various tutorials a bit confusing. I used MAGLDR V1.13 and successfully installed Pdaimatejam Rom Wp7.8 OS 7.10.8835.35 v8.5. My goal is to e able to dual boot the installed WP7 and MIUI_JB_2.9.14_NATIVESD. THIS tutorial, was followed to partition sdcard, but I'm still confused when it comes to installing the SDNATIVE Android ROM.
Do I install cwm?

I probably should state that my volume down button in not working by the way.

There is a sentence from those tutorial:
copy the "TOUCH" or "TWRP" or "RECOVERY" folder your SD Card (they all do the same thing)
you should copy recovery folder to sd card.

You can do hardreset from WP settings anyway. And magldr has looping menu, I think.

Maybe you should read more carefully?
Code:

All of this is jus REPLACEMENT of recovery. Then :
Code:
Magldr > Service > Boot Setting > AD SD Dir > TOUCH
Tap Install, notice that the compatible ROMS for this methoid have a div2 or NativeSD designation, tap on the ROM you want to flash.

lojjj, I too have attempted to follow that series of tutorials, and finally succeeded, but due specifically to the part you are mentioning, it took me HOURS. There is no "Touch", "Recovery" or "Tap" folder on a freshly partitioned SD card with 4extRecovery on it. The instructions are absolutely extraneous and cause confusion. Moreover, instructions for using HD2Toolkit to partition the card are useless for triple booting if one has already partitioned using a card reader in your computer. Yes, it can be done, but doesn't need to be done if one has followed the instructions up to that point.
The other problem is that one needs to combine three or more tutorials just to do this, and they sometimes have different options, but no reason given for choosing those options. This may be the best tutorial out there, pictures and everything, but still a far cry from being perfect or complete. Oh, and sometimes the tutorials are continued in another post, which also leads to confusion.

You're looking for this ones? The link provides at the top of first post. There are a lot of recoveries with NativeSD support. You need to download one of them, unpack and copy to root of SD Card. And then you can get to Magldr > Service > Boot Setting > AD SD Dir > Recovery.
Maybe I'm wrong cause I never did such things. Good luck :fingers-crossed:

[Q][HD2][NativeSD] Cannot find external SD in camera app

Hi,
I intended to post this question to the [3.Nov.2012][ROM] NexusHD2-JellyBean-4.1.2-CM10 V1.2 [NativeSD] thread, but not allowed to (http://forum.xda-developers.com/showpost.php?p=32624318)
Can someone help me redirect the question? Thanks!
First thanks for the great ROM, tytung. It looks great and easy to install.
I have a HD2 and wanted to dual boot WP7 and Android. Found this new method NativeSD and decided to try it. But once I installed the ROM (through MAGLDR 1.13 and Recovery 4Ext 2.2.7), everything works fine, except that the camera app (and other apps) says that it cannot find the external SD card to save the pictures. It does not give me options to save on phone. But since both system and data are on external SD, and that partition is treated as /mnt/sdcard0, I am not sure if I am supposed to have an external SD card from the perspective of Android.
Cannot seem to find similar post with this issue, so I must be doing something wrong with partitioning. Could you help??? Thanks so much! I am inches away from having a great Android JellyBean experience on my HD2.
Thanks!!!
-----------------------------------
Details:
4 partitions on my 16GB SD card:
1) FAT32, 3GB (this is the boot partition, where I installed Recovery 4Ext and through it, installed the boot files in /NativeSD)
2) Ext4, 8GB (this is the system/data partition, where installation put all Android files)
3) Ext4, 2GB (this is current empty, reserved for another ROM that requires two partitions)
4) Other, 2GB (this is a WP7 partition)
I formatted these using Mini Partition Tool on Windows (not via Recovery 4Ext)

I think you need to run CHKDSK on your FAT32 partition of the card with fix option, once, using a card reader and computer. Once done, put the card back to your phone and boot to your preferred Native SD rom. Then check whether you applications are able to trace the SD card. Should work, since the same worked for me, when I had a similar issue. Hope that helps.

Hi dheerajk27, thanks for your quick reply. Was wondering
1) should Android JB think that I have an external SD?
2) where will this external SD be mapped to? The Fat32 partition? The same Ext4 partition as system & data?
3) what would chkdsk do? I just want to make sure that it doesn't mess up the Win 7 stuff as well.
Thanks!

Hi braveliquid, welcome to the forum.
Did you set all your partitions as primary using minitool?
1. yes
2. depends photos/music => fat part, apps=>ext part
3. not sure either

Thanks for your reply. Upon multiple trial and error, I found out that the logical partition is the culprit. When I have 3 primary (FAT32, Ext4, Ext4), Android can recognize the ext SD card. However, when I have 3 primary and 1 logical (the Win Phone 7 partition is made logical by windows), then Android does not recognize the ext SD card anymore.
Any thought on how I can resolve this? Or else I will have to keep 2 SD cards, one for WP7, and one for Android. Doable, but a bit of a hassle.
Thanks!

use minitool and set your wp7 partition as primary too.
Problem solved.
you could use two cards, i am at the moment (I keep spare card in a cellotape pocket on inside of battery cover). You can also dual boot without partitioning see http://forum.xda-developers.com/showpost.php?p=34009754&postcount=1126 but only really as a backup phone in case wp7 goes wrong and you are away from pc.

Thanks Robbie. Yes, I have set the WP7 partition as primary and then it works! I am liking the Android experience (have been using iPhone).
Btw, in WP7, it is asking me to update software (I have a very old WP7 installation, migrated to dual boot in early 2011 i think). Can I just upgrade WP7 like normal (i.e. by connecting to Zune)? Or will that destroy MAGLDR? If that won't work, how can I upgrade WP7 to 7.5 or later 7.8? I cannot use Windows Market Place apparently with the old WP7 OS.
Thanks again!

I would just flash one of the new wp7.8 roms, your choice which. Ansar's does not seem to be able to use the new wpbackup app at the moment.
With Hd2o and pdaimatejam you can backup your phone and restore apps sms calls etc. Sooo much better for trying out new roms.
