Thanks,

Yes I managed to sort it out last night after I posted.

What I did was instead of dragging the partition to the right until there was 6gb left (which I wanted for Android) I changed it to drag the partition to the left to create a 6gb partition, this solved the problem :)

I have got wp7 installed just onto the Android now I tried the gingerbread one from here http://xdaforums.com/showthread.php?p=11417869 but it just hangs on the black HTC screen (so more reading to do for me :) )

HEY!!!

What about using an SD card reader and then a 2, 4, or 8 GB flash drive!?!?

That way maybe the 2 SD card method can used???

I will try it out after I take a nap. Me sleepy...
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
The two cards method is really only useful if you are upgrading from one card to a larger card. In that case you simply copy the WP7 partition from your old card to the other card.

2gb card for dual boot....seriously?? You need at least 4gb which will give Android just under 2gb and WP7 just under 2gb. I would recommend minimum 8gb to enable room for music, office docs, pictures and video clips. Also I have already urged people to use a card reader in post 1.

There is a good build like this based off the original GB and bootable via Magldr. MCCM is a very good build maker and has some excellent builds and the GB build can be found here.

I would use cope/warrenb's CM7 gingerbread for now.... mccm's build was just a themed version of that, and his download links have been taken down anyways for using cope/warrenb's work without permission.

You can find cope/warren's build here... http://xdaforums.com/showthread.php?t=957652

It already includes a folder with the files to make it usable with magldr and dualbooting.

I'm going to be adding more builds to the 2nd post tonight, too. I've been having problems with my computer corrupting some of the rootfs.img's, so I have to re-edit some of the builds I had already edited. If anyone downloads any of the builds from post 2 and they don't work, please let me know so I can correct this.

I am having trouble setting up Android from MAGLDR/SD after setting up WP7.

On boot into Android, the unlock screen shows up and it sets up SD card and shortly afterwards it gets stuck. I've let it stay that way for upo 30 minutes, but it is completely stuck. I think it might have something to do with partitioning on the card. I did try two builds, but both by the same guy.

http://xdaforums.com/showthread.php?p=10602424

This is the ROM I am trying to use.

I have accurately followed this guide and repeated procedures 2 times, as well as other methods and still no luck :(

P.S. I am a little new to SD Android as it is, to run this from MAGLDR SD I just need to change the config.txt.sd to config.txt right? [this is specific to this ROM I guess]

EDIT: It was indeed a config.txt error, I fixed it and it seems to work just fine..

EDIT 2: It still gets stuck at random, maybe the ROM is bad or something. Will report back after trying a basic Gingerbread ROM.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
Glad you got the issue fixed. A lot of people have problems setting up that build where just following the instructions by the chef is all what is needed most of the time. For this build a simple edit of the config file and adding an data.img made it work.

The golden rule is always follow the chefs instructions.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
My mistake, I knew he had been restricted in the past but by the number of builds he made threads for I had the impression he was allowed back in.

I look forward to seeing more builds in post 2 :D
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] hayyaan:
Yeah, well I followed his instructions multiple times.. they always seemed a bit ambiguous.

Anyhow, I am just going to try AmeriCanAndroid now. Let's see how it goes.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
Try out JDMS or HD2One from post 2 of this thread...those are my favorite builds. Both are VERY fast, have great battery life, and overall just work great. JDMS is an AOSP Ultimate Droid build, and HD2One is a CyanogenMod6.1 build. AmericanAndroid is becoming a very good build, too. The beauty of these SD builds is that you can have many builds on the same SD card, so you can test a few out until you decide which you want to use full-time. I have 6 builds on my SD card right now.

Also, I just updated post 2 with a couple more builds. I'll be putting more on soon.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
Unfortunatly with DL Desire build he has put how to configure the config.txt in a small link in the middle of the page and it isnt easy to spot but netherless he has a good build there.

Never tried the AmeriCanAndroid build so you wil have to let e know how it goes.

Stuck at the Black screen, Green HTC

Thanks for the tutorial. I wouldn't be anywhere without it.

I have WP7 booting fine and as near as I can tell, fully functioning.

I'm trying to put the AmeriCanAndroid build in the second partition, but my Android boot won't go past the Green HTC on black screen.

I had a couple of small issues in the tutorial:

1. Step 11 mentions "Settings" option in MagLDR. I'm using the latest (1.13?) and I don't see the option. It didn't seem important beyond verification of sizes, so I didn't worry. File Manager verified the sizes.

2. Minitools Partition Wizard wouldn't allow the empty space when I created the partion on the right. It kept using the whole space, so I created the partion on the left, and then another and deleted the on on the left (not 200M) and it was fine. Downloaded Minitools Partition Wizard yesterday, so it should be fresh. Running on Windows 7 (if it matters).

I downloaded the TMoUSA version of CM7 Gingerbread and extracted to my local drive. Copied the Android folder within to the SD card at the root. Replaced the two files in the Android folder with the ones from SDMagLdr sub-folder with renaming the one per the ReadMe. Selected the ANDROID folder in MagLdr and booted from the SD on the main screen (#2), but it sticks at the HTC screen.

Of course it's me, but what did I miss? I'm new to ANDROID. And this is my first attempt at Dual Boot. I'm using the 16GB card that came with the phone (SanDisk).
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
I'm glad the tutorial was of help and I will look into what you pointed out and make it clearer tomorrow. Golden rule....read the instructions by the chef on setting it up. I have never had this build on my device so sorry, I cant help at the minute but I will certainly look into it first thing tomorrow as it is late now. Just quicky flicking through though it says this.

'BOOTSDfromMAGLDR: includes optional rootfs.img that allows to boot build from magldr (!readme! in /Android/SDMAGLDR)'.

I suggest reading the readme which comes with it for instructions but it looks like simply replacing the rootfs.img should do the trick.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] Lurk:
i believe that this is the same build that Aenedor referenced on the first page.

The SDMagldr sub-folder has two files and says to copy them to the \Android folder and rename one (strip the second extension). I've done that.

I'm reviewing your instructions again and reallocating and formatting that partion (the first on the card). There was a note elsewher about a bad card format hanging an android build at the same point.

Also, there was a fresh release on the ROM today, so I've downloaded it as well. So far, no luck. I appreciate any help you can offer and I understand that you might need to sleep for 5-10 minutes every week or so. ;) WM7 is my primary boot, Android will be a "nice to have", so don't treat it as critical.

EDIT: Problem solved.

I'm not really sure what I may have done to correct it, but the boot time is long. I have waited over 30 minutes previously, so it wasn't my impatience.

I deleted and recreated the partition. Recopied the files and got very technical on the details.

Instructions:

-backup your original rootfs.img and startup.txt somewhere safe.

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

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

-copy startup.txt from this folder to /sdcard/Android

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

::

I moved the file it said to move and copied the file it said to copy leaving a copy behind. I don't think this was it either, but ...

Finally, in my search today I also stumbled across a statement about initial boot for Android disconnected from USB. I can't be sure I did that previously, but I did this time. And it works great!

Thanks again.

It's been almost a day since I started using AmeriCanAndroid. Simply put, I love it.

I was looking for a good alternative android to install apps and general messing about, but I like it so much that I might even use it full time :D

Everything works great. It works super-fast, even faster than any of my previous NAND builds (though they were all froyo). Battery life is also very good, It ate around 2% battery after 3-4 hours of standby and averaged 3mAh during that time.

The Cyanogenmod makes it all the more sweet.

Any way I can sync all my call history and messages between the two OS'? :D Then it'll be perfect!

I have my hd2 with wm6.5 flashed with latest rom, so I have the latest radio I think. I need to install wp7 I heard about hspl which needs to be installed. I am a totally noob. Btw my phone is t-mobile and spl 2.14. Can someone guide me to complete my installation.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] hayyaan:
First you need to install HSPL2. [make sure your current SPL is compatible, I am not sure]

You can then choose to do Task29(format NAND)

Then install MAGLDR

Install any build of windows phone 7, instructions on individual ROM threads

Then follow this guide to dual boot

I suggest you familiarize yourself completely with the process before trying something, use the search button extensively.. there are plenty of good guides and tutorials around!
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] agdroubi:
My spl is 2.14 and where can I download hspl compatible with it. Will Wm be removed??
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] hayyaan:
Again, I am not entirely sure about the SPL but I think you'll have to downgrade to an older stock ROM via the sd-card method to attain 2.10 SPL.

WM will be removed after you do a task 29 OR install MAGLDR

HSPL will not touch your OS.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] agdroubi:
What do you mean by SD card method???
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] hayyaan:
Flashing via RUU (PC) even to the stock ROM doesn't change the SPL.

You need to extract the .nbh image from the rom and rename to leoimg.nbh and place it in the root of the SD-card.

Then enter bootloader mode (Hold down Volume button while pressing Red/power button)

This might not work on sd cards bigger than 8GB.

Actually I have a 4 GB WP7 partition and 12 GB for Android. I got this with 2 cards. Initially I had WP7 on a 4 GB card. I copied that partition to a new 16 GB card and formated the rest in FAT32 and installed Android. It works this way. Both partitions are set as primary.

The bad news is that I would actually prefer to have 12 GB for WP7 and 4 for Android :)
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
Well you can do that with this method... you only need 1 card, and you can give 12gb to wp7 and 4 gb to android. You would have to start fresh with wp7, but it's not so hard now with all the pre-unlocked custom roms.

I have a 32gb class 4 sandisk with 22gb for wp7, and 7gb for android. Then I have a second 32gb card just for android (and ubuntu once magldr compatible version 0.4 is released). I keep the 2nd 32gb android card for keeping my music, psx roms, and comic books on, as 8gb doesn't leave much room for that on the other card, and I want to leave a good amount of space for wp7. This setup works well for me. Too bad they don't have 64gb cards... that would be perfect for me.

Are you erasing the folder you're suppose to erase after first boot? It's posted on first post of the Superram thread... it's an apps folder inside the root folder, I think. Also, are you shutting down correctly? Do not reset with this build or you can get data corruption... fully shut down and then turn back on if you want to reset it. See if either of these help.

3-way split??

Is it possible using this method to create a 3-way split on the SD card such that i can run

1) wp7

2) Android

3) have a partition which will act as the SD card (or external storage) when Android is running?

The reason i ask is because some apps. e.g titanium backup and more importantly form me, "CoPilot" SatNav software need to be able to access the SD card. Also it would be useful to be able to have a piece of my SD Card to act as a USB Mass Stoarge device?

Thanks

It is possible to have a 3 way split with an ext3 partition as your 2nd partition. It is only possible with the two card method. I am planning to include a tutorial for this in the next day or two. For every build to what I know to, simply editing the config.txt file will tell your Android build to save to data.img instead.

[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
The WP7 Roms, Magldr Android builds and Magldr are for HD2 only.

If you have WP7, Magldr or simular and Android which can boot with Magldr for the Evo then you could try this proceedure, but if not then

dont chance HD2 software on your Evo

or you could turn your phone into a very expensive paper weight.

Are you sure you are using an Android Magldr build? If you can let me know what build you are trying to install then I might be able to assist you further. If it is the Desire_DL build then you need to configure the config.txt file, how to can be found a few pages back. This one gets most people.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
As far as I know, Easeus see's the unformatted partition as a partition which is not formatted so only creates it as a primary partition. I recommend using Minitools Partition Manager as it can change the unformatted partition into primary, with Easeus, you cant do this.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
In most Android Magldr builds, with the exception of MarkinuXHDExtraClean and FeatherMiui, there may be a couple more, they come with startup.txt. In the startup.txt is a line which should say something simular to this, 'set set cmdline "rel_path=Android gps_zone=us nand_boot=0". If you change re_path=Android to rel_path=copeNwarren for example, then the Android folder must also be renamed to copNwarren too.

Example:

set cmdline "rel_path=Android gps_zone=us nand_boot=0"

Folder name 'Android'

to

set cmdline "rel_path=copeNwarren gps_zone=us nand_boot=0"

Folder name 'copeNwarren'

Hope this helps.

[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
I am afraid it is not possible to resize the unformatted partition so you must reset your phone then delete the unformatted partition to create another unformatted partition to the size you like. The size must be at least 200mb larger than the rest of the space available on your card and the unformatted partition must be created on the right.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] zarathustrax:
Actually magldr doesn't even have the ability to use the startup.txts yet (hopefully cotulla will put it in later builds), so there's no need to make any changes in the startup.txt when booting with magldr. Unfortunately, that also means any changes that you can make to builds through the startup.txt also will not work when using magldr.

Just a quick (and hopefully easy) question:

If we are lucky enough to receive a NoDo updated ROM soon, do i have to install Android also again? If not, i will try Dual Boot immediately today :)
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
If you want to keep the Android as it is setup without having to install anything Android related again, this is quite easy.

Since when using Android Magldr's builds, all of the data is stored on your card. Simply copy everything off your card into a folder on your PC/Laptop. For example, create a folder on your Desktop called Card Backup, insert your card into your card reader, select everything on the card and either copy and paste or drag and drop everything into your backup folder. Once copied, dual boot as you did before and then move everything from your backup folder back onto your card and Android should be as it was before.

I have done this many times before and I have never had any problems with this but as normal, I cant give any promises.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] Ryoukou:
Thats great, thanks!

Well, then i only have to find a nice Gingerbread ROM :)
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] AndHD2:
I would recommend American Android. It is very stable and suitable for daily use. Make sure you move the files for Magldr use into the main folder and of course you download the right one for the HD2 you have, ie Euro or Tmous. After first boot, restart and move the root folder from 240buildprop folder to the main Android folder if you dont like the smaller icons and interface. This will restore it back to the size what most Android builds use.
