I am having a similar issue. I got everything working with WP7 Twilight and JDMS SD ROM and had everything stable and working. Using android as primary. Yesterday afternoon I got everything all working well and fine and then when I woke up this am my phone was frozen...rebooted and it would not boot into android. Plugged sd card into reader and it prompted to format...sd card error. After some expletives I decided to go ahead. Only problem now is from a 16 gb card I now only have 30 mb available! Tried partition mangers and all and it is still not showing as full 16 gb avail.

Anyone have any suggestions?

FREEZES

Hello.. this is very frustrating, every android build i try just crashes!! i dont know what to do :(!!
[HD2 Windows Phone 7 Development] zarathustrax:
It is a pretty easy procedure. I'm not sure how the video in this thread shows how to do it, but the method from the thread in my signature is pretty easy.

Have you tried magldr compatible builds? Check post 2 in the thread link in my sig for all the builds I edited to work with magldr.

is any1 else having this issue

K so far gotta show mad love for the excellent work with the dual boot, however I wanted to know if any1 else has this issue I boot into both o.s. fine, but if i boot into android and use it for a little bit, and go back to windows 7, windows tells me I have to reactivate my phone even tho it was activated before and I lose everything all my installed apps, my contacts...the whole 9 yards, so wanted to know if any1 esle was having this problem and if there's a way arnd it ? thanx
[HD2 Windows Phone 7 Development] zarathustrax:
It sounds like when you boot back into wp7, it is no longer reading your sd card. Check how much memory space you have on wp7 when this happens. If it only has 10-15mb, then that's the problem. It could be that wp7 doesn't like your SD card if that's happening. Try a different SD card.

Important trick !

Don't know if has already been told BUT

I just install a fresh wp7 on my previous one but forgot to backup my android partition. As it was installed I thought ok, too bad but I lost all my andro settings.

In fact WP7 installation ONLY format at first boot (not during install process).

So I was able to backup my partition before wp7 delete it in magdlr usb host mode (before wp7 first boot) ^^

Think it can be useful if you're too in hurry like me ^^

HELP PLS..!!

HI,

I did everything as shown in tut (excellent work btw).

But when I click on BOOT AD SD, (the 2 option) it says SD open Kernel failed.

I did everything as you said. Even changed the name of rootfs img and startup and copied it to Android Folder.

Please Help

Thanks
[HD2 Windows Phone 7 Development] seizitp:
[SOLVED]

Forgot to Select the AD SD Folder under Services..

Works Fine Now..

Booted in less than 5 mins..

:D

To increase the bootup speed, just format the SD card using My Comuter with 64K allocation unit size, and then copy-paste Android..

:D

Thanx XDA..

Help

I have two 16gb cards and with both i cant seem to create the unformatted partition to the right leaving the blank bit on the left just after the reset. I have checked for errors, performed a full format on both cards but it just refuses to create that partition. Now with the 8gb card I have no problems at all and I can successfully dual boot but with my 16gb cards, all it does is says it is successful when partitioning only to leave only the blank unallocated partition i had in the first place.

I have tried with both Easeus and Minitool partition programs on both my tower and laptop.

Can anyone help me on this.

16 gig card

Using a 16 gig card that came with phone, and have been running WP7 with no problems for almost a month. Kinda missing some things about android so I wanted to dualboot. I'm following the steps, but when I use EASEUS, the only thing showing is 14.84 gig of unallocated space. That 200 MB fat16 partition is no where to be found. Any help on this would be greatly appreciated.

EDIT: I guess my adapter is screwy, and I don't have a micro reader, so I used magldr USB storage and everything seemed to work. Booting into Android now and it is taking a while...

UPDATE: After waiting 20+ mins at the HTC screen, I took the battery out and put it back in and still no luck with Android. WP7 boots fine though, got it up and running, live services and all, no problem. I guess I'm going to try a different Android build :\

UPDATE: Tried a different rom and it's working perfectly! Thank you so much for this easy-to-follow guide. HD2 is the ultimate device.

Excellent video!

Followed your steps and I can boot to Droid andWP7 no problems, thanks. I would like to try different droid builds - anyone doing this dual boot with a droid build other than the on linked?

If I use a differn't Andrioid SD build, do I still need to copy the 2 files (startup.txt and rootfs.img) on top of the build files?

I got a problem :(

Today i went and bought a brand new 16GB microSD card because i wanted to have enough space for both OS'

I followed your steps carefully but the only thing that shows up in Partition Manager is two Red Colors Partitions; both called "Other" (The Size is ok.. its around 15GB and 200 MB)

What can i do?? I did format the card.. i even reinstalled WP7 twice ;(

Is the Card maybe not supported.. did i waste my money? :mad:

If someone knows a solution please tell me :(

guese no one there to help
[HD2 Windows Phone 7 Development] zarathustrax:
So what's the problem? The 1st 200mb partition is the fat16 partition, the 2nd is the wp7 partition. Delete 2nd partition and create new logical partition for wp7 in the size you want, leaving it unformatted. Then after you got wp7 set up and using the partition you made, then erase 1st partition and create new primary fat32 partition using the rest of the space on the card. Then change the 2nd partition from logical to primary.

I have now just finished partitioning my 4gb SD with WP7 and Android (the Copes_AOSP_SD_HD2_GB232-CM7_A2SD_(04-02-2011) recommended on the YouTube video). WP7 boots ok. Android, however, runs into the same problem you mentioned. Exact screen capture is:

ssSDKernel open failed

I tried accessing he services menu (option 9 in MAGLDR 1.12) and select the AD SD folder under services but I can't seem to find such an option at all! at least, it does not present something intuitive to me.

Also tried going into the "Settings" menu but, again, MAGLDR does not show such a menu to me.

In short: I am lost :(

Can you help with a step-by-step cook-book shoing how to solve this?

I would greatly appreciate this!

When I'm booting Android from the sd card it seems to get stuck at 123456 GO! GO! GO!

I've tried to change to magldr 1.13 and I've tried three different radio's, to no avail.

Any help please?

EDIT: Never Mind, I just went through the whole procedure again, reinstalled magdlr 1.12 and I'm on the HTC screen so I'm hoping it'll work this time!

I just bought an hd2 with android 2.3.3 on it andmagldr 1.13. How do i install wp7 on it so i can dual boot? Can it be installed to the sdcard?
[HD2 Windows Phone 7 Development] fake:
It depends on your android build. if it's SD build, it's possible. If it's a NAND build, you have to install WP7 first and then install a SD build's Android.

If you decide to do this process, you can use American Android which is good and reliable and can be found here: http://xdaforums.com/showthread.php?t=957652
[HD2 Windows Phone 7 Development] fake:
Check this link out and choose whatever you want: http://android.hd2roms.com/

By the way I think american android is one the best in SD builds.
[HD2 Windows Phone 7 Development] fake:
I think you format your SD card after installing your WP7 and then install Androi. WP7 store basic settings on that unformatted partition after installing WP7. By formatting your SD card, settings will be reset every time you boot to WP7.

If u r going 2 downgrade to win 6.5 u should copy ur win 6.5 image file into ur memory card. Turn off ur phone. Turn it on while holding volume down and continue to install win6.5

didn't work...

Hi guys,

need your help.

I have followed the tutorial, but after installing the MAGLDR 1.13 phone doesn't boot, nor can enter in the MAGLOADER boot options.

So my phone is a brick now.

I have installed HSPL previously and the radio from this tutorial (Radio Leo 2.15.50.14).

Previously I only had WM 6 on the phone.
[HD2 Windows Phone 7 Development] Majidjan:
Just Relax.

Turnoff your phone, then go to bootloader ( turn it on while holding volume key down) , if the colored menu appears then :

- Try to install MAGLDR again and so on.

or

- Try to install Winmo by cable or SD card.
[HD2 Windows Phone 7 Development] dea.cristi:
Thanks.

It didn't work initially. However, I have downloaded and installed HSPL4, after this, I got the boot menu of aMAGLDR V1.13.

But, I got an error while installing WM7, the one attached, and the phone got to the stage as in the first video of tutorial at min 5:47. It is stuck. Any recommendations?
[HD2 Windows Phone 7 Development] dea.cristi:
Happy happy

Hi,

I have tried several configurations and now it's working.

After installing HSPL4 I have reinstalled the radio (one mentioned in this thread) and:

* first the MAGLDR 1.12 + WM7(DFT_LEO70_RELEASE) -> got stuck in same place;

* then, the MAGLDR 1.13 + WM7(DFT_LEO70_RELEASE) -> got stuck in same place;

* then, the MAGLDR 1.13 + WM7(HD2 1.01.00.WP7) -> got stuck in same place;

* in the end, the MAGLDR 1.12 + WM7(HD2 1.01.00.WP7) and it WORKED.

I am continuing now with installation of Android.

Thank you for all the info in this thread.

Partitions in SD card problem

Hi all,

I followed exactly the procedure. I installed WM7, reset the phone, took out the sd card. My problem: only one unallocated partition of 200mb is showing.

I tried with different sd card, same.

I tried reading with different card reader or the phone itself, same.

I tried different partition softwares, same.

I tried another WM7 rom, same.

So, i am really looking for help here. I now have installed WM7 only and it's working fine (32gb micro sd card).

Would really like to install both OS so any help appreciated!

thanks,

Mehdi

[HD2 Windows Phone 7 Development] Kritec:
Thank you for this awesome guide. As a matter of fact I owe you double thanks since it was your video that taught me how to flash in the first place. Keep up the good work

I will note a few things. I am running Xbmod v.1.10 with nodo and American Android. The rom you had included in link kept returning errors during extraction. I re-downloaded but that didn’t do anything. I compared the Startup.txt and edited accordingly.

Also I had allot of trouble formatting my 16GB MicroSD Class 10 since for whatever reason EASEUS Partition Master wasn’t able to detect it. I am using my Laptop with built in card reader. I used MicroSD Adapter to read my card. To bypass this I used MiniTool Partition Wizard. It detected the card right away. Also when resizing WP7 by adding the rest of the memory to 200MB partition I had to use MAGLDR's USB Mass Storage option to mount my card to be able to format.

It took me 2 times before I got it all figured out the 3rd and final time

Again Thank you very much!

ive done this alot of times. now im tryiing it again and having problems. whenever i get to resizing the the fat32 partition and put it back in the phone, windows 7 wont load. its telling me the card is damage or format had changed. anyone knowa why?
[HD2 Windows Phone 7 Development] bdaboy338:
sethin for me, have u figured it out yet?
[HD2 Windows Phone 7 Development] LuckTR:
Happens to me each time I am setting up dual boot. All you have to do is flash WP7 again. Partitions will carry over hence you'll end up having your working WP7 install only allocating exact size of unformatted space that you've designated via Easeus... Only thing left is to create the Android portion, format it Fat 32 FS, copy your build of preference on it, set WP7 part as primary and off you go ;).

Hope the reflash method will work out for you :)
[HD2 Windows Phone 7 Development] bdaboy338:
everytime i reflash the card formats and all the space goes to wm7
[HD2 Windows Phone 7 Development] bdaboy338:
i keep messing this up. can u give me the exact steps. what partition to i make first.

I tried making the fat32 first and leaving the rest as unallocated space, then intall wm7 and that didnt work. what do u mean by partitions will carry over when everytime i flash wm7 it format the card and takes back al the space.
[HD2 Windows Phone 7 Development] mfrey0118:
Well, quite an adventure for sure and it took me all afternoon. I had been planning to try a WP7/Android setup for a while because I had it work (kind of) in 6.5.5...but what finally motivated me was that my wife loves this scrabble program called Words With Friends and she plays with her sisters all the time. I wanted to play her but was dismayed that Windows Phone Marketplace did not have it. So I figured if I get Android in here, we'd be good to go (she has MT3GS).

The biggest problem I had was that EASEUS would not work for me. For some reason, it refused to see the SD card. So I had to figure out how to do it all with Paragon Partition Manager 10 and MiniTool. Then I had the partitions backwards, FAT32 > Unformatted > unallocated. With some little 7mb partition in front of unformatted that was stopping me from modifying any of the other partitions (over 3 and the program will prevent it). So I had to wipe and start over...

I should note that resizing the partitions and moving them was much quicker in MiniTool then Paragon. Paragon won't do it in Windows, it forces a restart and then does it VERY VERY SLOWLY in a DOS setup that takes about 2 hours. MiniTool took about 10 minutes.

It still wasn't working, and I already had been at it for several hours and was about to give up, when I realized that I had not set the unformatted partition as primary. Once I did that, bingo, dual boot setup works flawlessly.

I just finished downloading all my apps from android and windows marketplaces, and I was able to instantly side load all my .xap's without redoing the unlock procedure. Nice!

My advice for those having problems is to go back over the instruction videos carefully and redo all steps in order before hopping on the forum looking for help. That's how I fixed all my issues.

I no longer miss 6.5 and it's customizability and the FREAKING PROPER BROWSER TEXT RESIZING WHEN ZOOMING of Opera 9/10...

I am using Sandisk 16GB class 2 SD card and so far I haven't noticed any degradation in performance from either Android or WP7.

Thanks once again XDA, for keeping my HD2 a sweet-ass phone!
