hi.. does the wifi work for u????

if yes then how did u get it working?????
[HD2 Android SD Development] ahmedsalem89:
Make sure u did this step

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://xdaforums.com/show...&postcount=372

Android destroyed at new WP7 install.

Hi all,

After having done all this, and have WP7 in Nand, Android in SD and booting via MagLdr v1.13, i have an issue when i want to upgrade a new WP7 build.

Once new WP7 is installed in Nand, when i boot it, my Android partition is DESTROYED and i have to go through all this Tuto to partition my SD card again!

Is there a way to tell (at first boot of this new WP7) to "not re-partition" the SD card. Use it as it is??

Sorry if this has been already answered.
[HD2 Android SD Development] darrengladysz:
No and I don't there will be as the issue is with WP7. Best advice is to copy your android folder to your pc before flashing wp7 and then follow instructions to partition sd and copy it back.
[HD2 Android SD Development] Beatazor:
Maybe some1 made nice bootload application (to select btw android / wp7 loading) which can be flashable and accessable before magldr loads? Or after it, or from it.

Btw is it possible to make wp7 and android with ext3/ext4?

Htc HD2 with wp7 and android Dual boot overheats wi SD card

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.
[HD2 Android SD Development] kergekecske:
i use wp7 and sd android with mgldr

i have three partitions fat32/11gb , fat16/200mb , wp7/4,5gb and some unallocated space around 80 mb

i decided that i split the fat32 to fat32 - ext3 - linux swap -- to improve android performance

i resized the fat32 , after i created the ext3

and after this .....

the partition tool said : there is no more space in mbr for another (new) partition

so the question is :

one sd card - four partitions and some allocated space - is this the limit or I made a mistake? :)
[HD2 Android SD Development] cu2cool:
Hey kergekecske,

How did you manage to make the fat32 partition larger than the WP7 partition? Did you use the one or two sd card method?
[HD2 Android SD Development] kergekecske:
two cards (16 / 4 )

partition copy

perfect ...

btw i had issue with one of my 16 gb cards

so i think not all 16 gb sd good for it

i mean the double partition because this card doesn't work with wp7 but not works with dual partition although the method was the same.

i dunno the exact reason ...

so i changed the card ...
[HD2 Android SD Development] kergekecske:
possible

it works

i have problem with swap partition
[HD2 Android SD Development] mateuszd:
I followed the single SD card guide and have the following layout:

Primary Active Partition 6GB FAT32

Logical Partition 8GB WP7

WP7 works and shows 7.99GB, Android boots from SD but does not mount the SD card. I tried two different builds. Am I missing something?
[HD2 Android SD Development] futureshock:
same problem for me... i don't know either...

when i copy my android files on my old 8gb card (i use normally a 16gb card... 10gb for wph7 and rest for android) it works a usual.. have an running/"inuse" data.img file...
[HD2 Android SD Development] mateuszd:
I tried to repartition the SD card again from scratch but WP7 keeps partitioning it by itself :(

There may be something wrong with 16GB cards :/
[HD2 Android SD Development] futureshock:
do it like in video explained...

start up wph7 do a factory reset...

after in magldr put out sd or go into masstrg. and remove and recreate an unformated space....

this works 100%!!

but i think propably the android partion don't have to be smaller than the wph7 else it wont work...

i test now with a complete wipe of the sd...

with only android on it...

copied the wph7 part to a free unallocated space on my hdd in pc :D (windows 7 didn't now the filesystem and wants me to format it ... haha :D)
[HD2 Android SD Development] HQRaja:
I followed this 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 the one SD card method with 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 517588

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 Android SD Development] zarathustrax:
You must use minitool partition magic to change the wp7 partition from logical to primary... I believe those instructions were added to tutorial. Once both are primary, android mounts card fine. I've included minitool to post for convenience.
[HD2 Android SD Development] mateuszd:
Thank you a lot, it worked! My new partition layout is:

Primary Partition +- 5GB FAT32

Primary Partition 1GB EXT3/4 (just in case)

Primary Partition 8GB (Whatever FS WP7 Uses :D)

I assume that when you first create a logical partition WP7 thinks that it's all allocated for it even though it's not (we give it some space for the end of this logical partition) :)

I noticed that the unallocated space is actually a logical partition which is later allocated to the FAT partition. When we convert both of them to primary partitions WP7 feels cheated but can do nothing therefore accepts the new layout :D

Am I right (at least a bit)?

BTW. Just found out that DL Desire Android build ate my WP7 partition instead of converting the EXT3 partition to EXT4...
[HD2 Android SD Development] ohiosux:
I tried every partition ordering I could think of. After having concluded that the supposed method to do the single card method with the Android partition being larger than the WP7 partition is not possible, I did a pseudo two card method. So what I did was take an 8gb card and made the WP7 partition about 6gb (unallocated 1.8gb). Then, I copied that to my 16gb card. Voila! The inability to control how WP7 tramples an SD card is pretty ridiculous.

Hi, i just tried to make my dual boot hd2 ready. everything seemed to work till i booted the android from sd (Gingerbread CM7). it runs till the cyanogen boot animation and now it's frozen. what to do now? where could i've made a mistake? Both Partitions are set as primary!

Pls help!
[HD2 Android SD Development] zarathustrax:
Did you replace the rootfs.img with the one in the magldr boot folder that's in the build? You have to rename the one in the folder to rootfs.img before copying it into main build folder.

it froze on HTC white screen

[HD2 Android SD Development] nzxtneo:
mr brew must of been smoking something, because that $%# don't work...

So for anyone wanting to

dual boot WP7 and Android

, while having a larger partition for Android..............

Here you go (finally!!!):

(I created a 4gb WP7 build and allocated the rest to Android)

Copy everything in this vid exactly!

http://www.youtube.com/watch?v=JTHRAUHZHlo

(I used an 8gb SD card for this step)

Then connect the 8gb SD and a 16gb SD to a computer via card readers. (Yes this will be a 2 SD card process)

Open EASEUS Partition Master

Delete any partitions on the 16gb SD so that it reads as unallocated

Hit apply

Right click the unformatted partition of the 8gb SD and select copy

Move the unformatted partition to the larger unallocated SD card

Drag the 4gb partition all the way to the right

Hit apply

(Please note the move step will take a long time)

The unallocated partition is now ready for you to format for use with Android :cool:
[HD2 Android SD Development] ohiosux:
Contrary to popular belief, I think you actually need 3 partitions. 1 for WP7, 1 for Droid, and 1 for Droid data (ext4). I have 2 partitions on my card and Android runs like dirt. Complains about no SD card being present, etc.
[HD2 Android SD Development] zarathustrax:
That's because you forgot to change your wp7 partition from logical to primary. It's a very important step... otherwise android will not mount sd card. Use minitool partition magic to do this. 2 partitions are not needed.
[HD2 Android SD Development] libreee:
I think so, there's no way to run it...

I'll try your method, thanks you!
[HD2 Android SD Development] darrengladysz:
Let me know how this methods works out. It seems that the one posted by Mr. Brew is difficult to achieve and I can propose this one if it works.

I've mostly used the 2 card method. It is longer but it more reliable.

Thanks
[HD2 Android SD Development] zarathustrax:
Yeah, that method would work... I've done it several times in the past to make a smaller wp7 partition. It's just combining the 1 card method and 2 card method. Just use 1 card method on a smaller card depending on how big you want the partition (ex... if you want 2gb partition for wp7, use a 4gb card, etc.)... then once you have it setup ok on smaller card, copy your wp7 partition over to the end of the bigger card you want to use. You can use this method to make any sized partition as long as you have a sd card from the size to double the size of the needed wp7 partition.

I've got a few ideas I'm going to be testing out next time I repartition my card about how to make any sized partition with 1 card method, and an idea on how to keep partitions set when you change wp7 builds (it would still reformat the wp7 partition, so you would be starting over with wp7, but it would leave your fat32 partition alone, so you won't have to go through the process of repartitioning when changing wp7 builds if it works) I'll post my findings once I get a chance to test.

[HD2 Android SD Development] nokn956120:
I have tried the one card method for dual booting and i am having problems.

I have tried with two 16gb cards and it is the same on both my laptop and my tower.

When it comes to deleting the large unformatted partition and create a new unformatted partition just slightly larger than half the size of the card, it says successful only for it to leave just the unallocated partition the same size as the unformatted partition was which i deleted (the size before deleting the first partition).

I have also tried the two card method but when i copy the unforatted partition fro my 8gb card to the 16gb card, it fails to copy only to leave a blank unallocated partition.

Now when I try with my 8gb card, both methods work flawlessly.

I have done a full format on both 16gb cards and checked for any bad parts on it but they are both sound and work flawlessly with Android.

Triple booting

I was lead to believe that triple booting as possible, am I missing something or perhaps misunderstanding something? this link

http://www.techautos.com/tag/triple-boot/

Hey guys,

nice guide, but i still seem to have some problem.

I have a scandisk 4gb class 2 sd where im running WP 7 with. When I reset the phone, and it goes to the MAGDLR menu (and stays there), I remove my sd and put it in my adapter. In the pc it says that it needs to be formatted if i want to use it, when I do this I only have a 200mb card.

If I don't, and open it in the partition manager, it shows a disk with 200 mb of unlocated space, there is no other partition..

Anyone who knows what to do to fix it? I'm sure its a 4gb card, used it in my Nokia before (3 months).

Any help? Or tips? Thanks!
[HD2 Android SD Development] fuziontab:
cool, i really want to try this out!
[HD2 Android SD Development] cu2cool:
So are you saying it already works with WP7 on it? If so, the WP7 formatted space should be visible in with the EASEUS software mentioned in the first post.

If all else fails, you can try formatting the card in the phone or computer and start over.
[HD2 Android SD Development] dersna:
Yes, I can flash WP7, been using it for about 2 days and its working nice. Wanted to try with an SD Android partition, and actually got it working.

To reply to your tip, I've been formatting and formatting a few times. Strange thing was, no matter how, when I flashed WP7 and inserted the card in my adapter, it only showed a 200mb partition (not even fat16, unformatted or something). When I tried to format it in the partition program, it only found 200mb, nothing more. Also when formatting in explorer, same result, just 200mb nothing more. When inserting in my HD2 and resetting WP, it did found more mbs, the full size.

Then I decided to check it with my N78 (red something about it somewhere on google that nokias can do a lot with SD's). I could open it in the N78 and format it (although it said damaged memorycard). After that, I had my 4gb back. Then I just tried to use the card in my N78 as mass storage (after the WP7 resetting and restarting) and then my pc did see the 2 partitions...?! Strange, guess its my scandisk adapter that wasn't able to read it. Tried it afterwards with another SD and same results!

Now its working, the first boot in WP was buggy, it got stuck and rebooted on sync with my Hotmail account 2 times. Now its running nice, also my SD Android build! (using AmeriCan Droid). THanks for the tutorial!

[HD2 Android SD Development] dersna:
it took me some time to get past the htc bootscreen.. more time then usual (first sd boot under wp7) compared to sd build from wm6.5 or a nand.. Just give it some time? How long did you wait?

If you're stuck, maybe try to copy your android build again to the SD and remove the old files..

Windows Phone 7 keeps on formatting the card

Hi

I'm attempting to use the THIRD method (single SD) and I'm having problems with WP7 always formatting my 32GB SD card. I've followed the guide step by step and split the card down the middle obviously giving WP7 (on the rightmost side partition) the most amount of disk space.

When I get to step 7, WP7 always resets the SD card to the full 32GB. In fact, even when I don't perform a full phone reset, WP7 clears the partitions back to 200MB FAT and rest unallocated space. I've read the guide word by word, so I don't think I'm doing anything wrong. Is it a problem with my memory card?

Any help would be appreciated, its really doing my head it! ;)

i am trying to partition a 32Gb in this way

24gb android

8 gb wp7

i firstly tried the single card method, but i did not work (wp7 reformats the whole sd... but it is written in the guide that the wp7 partition must be bigger than the other, so i quitted)

i then tried the 2 cards methods.

i used an 8 gb sd, reformatted completely by wp7 .

i copied the 7,8 gb unfomatted partition creatd in this SD to the 32 Gb SD an copied and resized the fat 16 parttion to occupy the remaining 24 gb.

when i noot WP7 it does not recognize the almost 8 gb partition, it says it only has 10 Mb space available...

any advice to solve this issue?
[HD2 Android SD Development] ketzazu:
Yes. That is how my card is partitioned. Watch the youtube tutorial video in the WP7 section on how to do it. The written guide leaves some stuff out.

And if you can use a different card for android, that will be much easier. All you have to do is to boot the phone and hold down the power button to access MAGLDR screen, then remove and exchange the SD card for WP7 or Android, and choose the menu option to boot the OS [WP7 or Android] in your card.

That way, when you update your WP7 you don't have to worry about repartitioning your card again and recopy your Android build.And you end having more space on anddroid card to try out more than 1 build uy another 16gb card for Android itself. The 32Gb microsd is more expensive than buying 2 16Gb microSd cards. Get at least a class 6 card.
[HD2 Android SD Development] ketzazu:
Watch the tutorial video on the WP7 forum oo how to do it. Remember that the size of the partition for Android must be smaller than the size for WP7

I use 4 different cards with various builds on them. I still have my main WP7 card with my favorite Android partition on it. All I am trying to say is to use the whole 32Gb for WP7 and a whole other card for Android.

WP7 has the potential to be a killer. I use it to play my music because it plays louder than my Android builds. With the advent of WP7 mango, the only reason I bootup to Android is for Apps that I use that are not available yet for WP7. An example is an app called "Words with Friends" available in the iOS and Android platform and not in WP7 platform.

With WP7 Microsoft has given birth to a Bomb that can blow both Android and iOs away if Microsoft can manage to translate the iOs and Android apps to the WP7 platform.
[HD2 Android SD Development] ketzazu:
I may be wrong but I think you have to flash over NAND WP7 a new WM6.5 Rom and then go NAND with Android from WM 6.5.

Go to the NAND Android forum for their guide on how to do it.

And I just read that NAND Android Roms are causing Badblocks problem. A NAND Android may not be a good idea for the life of the awsome HD2. NAND Android may be carcinogenic to HD2.
