32 Gb SD

I have a working dual boot 8Gb SD, so let's assume i managed the whole process more than once.

Now, as i stated before, i have problems with 32 Gb Sd cards.

I tried with 2 32 Gb Kingston microSD and i had the same problem with both :

when Wp7 restarts after the second reset, it does not formats and uses "its" partition (let's assume i have prepared a 16 Gb partition, unformatted, for WP7) but it reformats the whole SD, 32 Gb, leaving no space for poor android.

Now my question :

has anyone succeeded in using a 32 Gb SD with dual boot?

if yes, which brand?

I would like to understand if the problem here is the sd itseslf (a fake?) or , perhaps, the size.

Thank you.
[HD2 Android SD Development] devilman:
sorry to bother... but sometimes upping a post helps...

no news about my question?

has anyone succeded in having a 32 Gb card working in dual boot with both the systems?

thank you and, again, sorry for reposting the same question.
[HD2 Android SD Development] hyellow:
I have a sandisk 32gb class 2 and I have it working all the time.

I switch different wp7 roms on a regular base.

First flash a wp7 rom with your 32 gb sd card inside. Then go to the about screen en verify you have 32gb of storage (usualy it's around 28gb). When that is done, use the reset button in the same about screen and wait untill your phone restarts and stays in the magldr menu. It is important that when the phone restarts and upon boot stays in the magldr menu, otherwise it'll boot into wp7 again and starts to factory default your wp7 ROM.

If it stays in the magldr meny, you can remove the sd card and go partition it. remember to set it as logical partiton first and when all is set and done, convert it to primary afterwards. remember, with my method, it is important that the wp7 partition must be greater ( a few mb's will do) than the android partition, otherwise it will fail.

please check the instructions on the first post for more details. Use the single sd card method.

good luck
[HD2 Android SD Development] devilman:
Firrst of all, thank you for your answer.

I made exactly the steps you mentioned here, but when WP7 resets for the second time, it uses the whole 32 Gb SD (reformatting it) instead of the unformatted partition just prepared for it.

i tried twice with 2 kingston...

maybe the brand here is important?

I will try with a Sandisk.
[HD2 Android SD Development] hyellow:
have you made sure that you were resizing the unformated partition and not the 200mb fat16 partition. The wp7 partition should be the second in line or the rightsidw partition.

WP7 Reported Wrong SD Storage Size

Hi,

I'm using the 2 card method to dual boot, the method provided by NZXTNEO. Everything went fine and Easeus Partition Master reported the correct size for WP7 and Android, which are Unallocated 4GB, FAT32 14GB.

Booted into WP7 or Android fine. However, when i went to WP7 and check the storage, it says the total storage size is only 100MB. I have rechecked with Easeus and Mini Tool, they both confirmed that the 16GB SD card has only 2 partitions, and they are both correct size.

can anyone shed some light on this issue?

thx

I already tried all of these methods. They never work on the new Mango final build.

For the final Mango, sdcard locked whenver you turn off or just ON the phone. even, I tried to unlock the Sdcard by using the StorageLock in the WP7.... Please find out a new way, our experts!....
[HD2 Android SD Development] lyh1:
you need StorageLock to unlock the SD Card every time you turn off the WP7.5.

When the WP7.5 boot again, the SD lock again.

Very Annoying, but it still work.

I have a problem ifter i've installed android the hyperdroid rom i cannot boot wp7 i have this message wph not installed.I use the yuki's mango final biuld and the last update of hyperdroid.I use a single sd card because there are cab in wp7 thay can split the storage on my sd card.After the cabs i've just isntalled the android rom but after the boot image which is from wp7 i can only boot android :(
[HD2 Android SD Development] anseio:
I'm lost here.

I've tried using two different SD cards. Upon resetting WP7 and stopping the reboot while in magldr, I put the SD card in my reader and into my laptop. EASUS and diskpart NEVER show anything other than a 200MB unallocated partition. Not once have I seen a 200MB FAT16 and another area of unallocated space.

So, when I try the method in this tutorial, or the newer method using the extrastoragexxGB.cab, I cannot see the WP7 partition to make it primary. This pretty much locks up WP7 and the only way to rescue my SD card is to completely reinstall.

I don't know what I'm doing wrong, but am annoyed that this seemingly easy process is not working.
[HD2 Android SD Development] anseio:
Solved - dunno if it's a Win7x64 thing or not. Booted into Parted Magic for GParted partition manager and was able to see the partitions as described in the tutorial. Wierd.

No luck with methode single SD card

Hi mate, i have been trying for 2 days now to do this but cant seem to manage, my problem is that when i put the SD card in the computer (windows 7) a notice appears saying: You need to format the disk in drive I: before you can use it.

So i just cant get past this step, i look at the card in EASUS and it says Unallocated 200 Mb.

Could you please give me a hand for i do not know what the problem seems to be.

Thanks a bunch!!

Dual boot with Mango 7740

Hi,

I tried the steps mentioned for single SD above but that were not seem working for me straight as mentioned there were some steps missing. I would like to tell you exact steps that I followed.

My configuration:

Device: HTC HD2-Tmous with default WM6.5, r2.15.50.14

SD Card: 8GB sd

WP7 Rom: Back to the Future[XBmod-Yuki][Updatable]

Android ROM:[SD/Magldr][BoxmaX KS v9.0.Final][DesireHD GB 2.3.5 +Sense3][K:ty r14+RCMiX6]

After step 2 below you must eject the USB cable from phone as it would restart you phone while you actually want it to be shut down in some steps.

Steps:

1) Flashed Wp7 as mentioned in the WP7 ROM url above

2) Installed DEV_STORAGELOCK.cab (google it)

3) unlock the sd card using storage lock

4) reset phone in WP7

5) while restart hold End key (call end button)

6) wait on Magldr screen and pull sd card.

7) Insert SD in PC, now the sd card is viewable in EASEUS

8) Drag the Unallocated partition from left to right (so left space is 3.5Gb and right one is 3.9Gb)

9) Apply changes and after completion pull SD from PC and insert into HD2, Press green button and WP7 will boot.

10 Verify storage space in WP7 it appears as 3.9 Gb.

11 Power off Wp7 wait for complete power off (should not do while you plugged in the USB cable or charging)

12) Pull SD and put it in PC, now you can see 3 parts in EASEUS - Fat16 Green in Left and two grey parts in right.

13) Right click the Fat 16 and select Move/Resize. Drag it to fill the middle grey portion and apply.

14) Now you will see only 2 parts left (android) and right (Wp7). Right click the left part and format it with FAT32 using 32 kb (that is only available for me but you can choose 64kb also if available) Apply.

15) Pull SD from PC and insert in HD2.

16) Start the phone holding End key and it will boot to Magldr menu.

17) Plug in USB, select USB storage, copy android build to sd card (make sure you copy Magldr build and not the sd build).

18) After copy complete eject USB and go to service, select booting select AD SD directory, move back to main menu and select boot AD SD.

Your HD2 is dual booting now.

WHEN YOU ARE IN WP7 AND WANT TO BOOT TO ANDROID PLEASE CHECK THAT YOU CARD IS UNLOCKED, RUN STORAGE LOCK AND READ THE INFO IF IT IS LOCKED THEN UNLOCK ELSE ANDROID WILL NOT BOOT.

I think this will help you people out.

unallocated 200MB???

Hi All,

can any one help please, i have tried all method, still show "unallocated 200MB"

when i remove the card from pc and then put it back to the phone, it

wont work, showing "storage card not working"

i then reset the phone and still showing "unallocated 200MB" on PC.

i have tried 2 HD2 phones and 2 SD cards, same problem.:confused:
[HD2 Android SD Development] ukjeeper:
I have followed the instructions, and appear to have it correct as i now have a 1gb ext4 partition and a 256 'swap file' partition on my 16gb card.

However my internal memory remains at 200mb and i'm constantly getting 'low space' warnings.

Don't think i missed anything. I'm running one of the ICS roms, don't know if that affects anything. Thanks.

I have heard Xperia phones do not Support Boot looping which is required for Dual Boot.

Is their any Kernel available for Neo V that Supports Dual Booting..

Please Answer

Thanks
[HD2 Android SD Development] pakure:
the easiest way to partition : in 5 minutes

another way to partition sd card: much easier way

1. you need a wp7 rom which allows xbmod cabs certification (eg: pdaimatejam or hd2owner rom)

2. after flashing wp7 rom, using cab sender, send xbmods sd partiton cab of your required size, to the device

3. go to settings/about/more/reset your phone (hard reset):rolleyes:

4. done, check size of memory in settings/about:D:D:D

5. shut down phone, take out sd, put android files on the sd and enjoy:D

i have already a dualboot but with android roms

i want android/Windowsphone
[HD2 Android SD Development] gazzacbr:
Just a quickie, can i do this with a spare card and then image the partitions on to another, bigger one?

Yes, and thats the best way to do it. then you get a small WP7 partition (about half the size of the first card) and when you copy it onto a bigger card the rest is all for Android

Sent from my HD2 using the power of ICS :-)
[HD2 Android SD Development] gazzacbr:
hmm, and youre asking in the HTC HD2 Android development forum?

my advise is to not try anything in here on your phone.

you would really need to go to the Samsung Galaxy S2 Windows Phone 7 forum.

Core Droid HD 0.4 Desire HD Sense build works for dual boot

Hey darren,

it's me again ;)

EDIT: IT WORKS NOW THX TO DAYSEY!!!!!!!!!!!!!!!!! He supplied me with the correct init.rc which is attached under this post.

I got an Android SD-Build to boot with Magldr. Had to edit a init.rc file though which was quite a hassle ;)

Anyway, the Build I could boot over Magldr is:

Build Name: Core Droid HD 0.4 It's a Desire HD Sense build...

http://xdaforums.com/showthread.php?t=801607

(This was my favorite sd build which I used over a month with no problems. It's fast and smooth)

Follow the link to get to a tutorial I wrote to make it work easily:

http://xdaforums.com/showpost.php?p=10689007&postcount=1106

Solved (see my later posts on this page) What went not so good:

I followed your tutorial to make the two partitions...after more than 2 hours the formatting was done and I tried to boot up WP7... WP7 didn't detect the sd-card at all, meaning after boot it shows no device name and you have only 15MB of storage...

Did a mistake then, chose to reset device under WP7 which caused WP7 to create new partitions during boot, so all the work was smashed...

Do you have a tipp for me what I could do that WP7 detects the SD-card (or the created partition) during first boot??

Do I have to reset sth via Magldr between creating the image on the small card and putting the formatted large card back later??

I want get this thing to work!

Greetz Dom

EDIT: Here is the edited init.rc file, but as I wrote in the linked tutorial, the actual hassle for me was to mount the rootfs.img...

EDIT 2: To peops who are having the issue that android does not detect the sd card... Try this solution posted by scrondone:

http://xdaforums.com/showpost.php?p=10725793&postcount=119

I can't really try it out myself cause I have never faced any sd issues (tried multiple builds on multile cards), but the approach sounds very promising to me (makes just sense ;))

Credits go to scrondone for this solution!!!!!
[HD2 Android SD Development] darrengladysz:
I had no issues with wp7 not detecting anything. Wp7 acted as if I did not even change the sd card.

Make sure fat32 is your 1st partition not the 2nd. Re-read my instructions. I had no problems with this. BTW used a windows vista to move/resize the partitions. Again 2 partions, one fat 32, re-format it to 32 or 64 kb sectors and the wp7 partition in 2nd place. It is ok to have a few mb left as unallocated.

Second thing. Make sure you enable dual boot with menu in magldr as per my instructions otherwise you will load into wp7 and wp7 will reformat your sd card.

Are you using a sd card that wp7 is compatible with. Seems at present it is mostly sandisk class 2 cards. Look in the hd2 wp7 general forum. You may have a sd card issue.

I do not know if this may help, but I sometimes click hard reset AD in madldr but not sure if this does any good. I think this is for later when you try to load android from sd.

Also, if you could post the modified init.rc file it would be nice.

Presently trying to get a desire hd sd build going. Tried Superram but it was a no go.

Let me know.
[HD2 Android SD Development] jessesam:
Does anyone know how to go into magldr without going into windows7 ?
[HD2 Android SD Development] darrengladysz:
As per my instructions, hold the end call key during boot.
[HD2 Android SD Development] ricola7:
thx for the quick reply!

What do you mean by that. I mean I followed your instructions regarding setting dual boot in magldr anyways. But theoretically, if i boot WP7 via dual boot it is going to "load into WP7" too! (cause this is the whole putpose of the dual boot, right ;)) Is there a difference if WP7 boots directly or is started manually via magldr (using dual boot)?

EDIT: Doh...I think I new what was my mistake. After applying all the changes in magldr to dual boot I pulled the battery out to start magldr again...I read somewhere now that taking the battery out is like a hard reset for WP7...which may be the reason that it couldn`t read the partition anymore...

I repeated the whole formatting process and now I have a correct partitioned sd card again, but actually I'm not sure if I pulled the battery out again somewhere..fck.

I guess I have to try *lol*
[HD2 Android SD Development] ricola7:
Regarding sd card, it is compatible with WP7, tried it a few times before...

I can attach the edited init.ec file here (I guess it`s okay with the dev cause Android is open source ;)). But actually the hassle was not to edit the init file itself but to mount the rootfs.img. So actually it would be better if I could post the edited rootfs file...problem it is too big to attach it here (16MB). And I have no account for a mirror like hotfile or rapidshare...
[HD2 Android SD Development] darrengladysz:
Hi,

Hmmm I do not have an account either. We should find a way to upload these as you can then just subsitute them in the build and get it working. At 16mb it is also too large to email.

BTW desire hd build 4.0 from mccm did not work :(

As for madlrd, yes you got ir right. There is no diference if you boot automatic or manual. My mistake, wrote too fast. Just wanted to ensure that you did not reboot wp7 before the process was over.

What os are you using - I used vista? Also, do you move and resize the 200mb fat partition?

For me, I got it going 1st try.

Edit: Are both your sd cards wp7 compatible? Are you using a fresh wp7 install or trying to copy the partition from one that was used for some time?

Thanks
[HD2 Android SD Development] ricola7:
THANKS for your effort darren... I got it to work now too. Guess it was the pulled out battery during the first try.

So what do we learn...never pull the battery out while running WP7 (hopefully it never freezes for me ;))

EDIT: Attached the init.rc file...
[HD2 Android SD Development] ricola7:
Doing this with only one card...

Hey...

Maybe somebody can try this, cause I'm setup perfectly right now and will not screw around with that...

Isn't it possible to:

1. Taking your 16GB SD

2. using EASEUS Partition Manager to create a fat32 partition (8GB) (called partition A) and a dummy partition (8GB) (called partition B) which WP7 can not delete/overwrite/whatever (like ext2 oder sth like that)

3. pull battery out and than in to hard reset WP7

3a. put SD in the device

4. boot WP7 and let it repartition partition A

5. shut WP7 down and take SD out of device

6. reformatting partition B to fat 32

7. put android on B

8. SD in device

9. boot wp7 or android

Should be easier and much faster, if sb could try that and report back would be great...

[HD2 Android SD Development] darrengladysz:
Tried ext2, ext3 and ext 4. None work. Wp7 deletes them all...
[HD2 Android SD Development] jcsy:
i think WM7 deletes everything on the sd card, whether u have partitioned or not

clearing all the tables and partitions created
[HD2 Android SD Development] ricola7:
Damn ;) Would've made the process much easier...Send you a pm by the way
[HD2 Android SD Development] tigerlocc:
Hey Ricola, That does look to be a good idea. Maybe someone can try that out and post the results for us.

edit: Man that was fast darren hey at least we know for sure now

As for the Android build for the SD card - I browsed around and came across a tutorial that details how to do this:

http://xdaforums.com/showthread.php?t=913964

It's similar to what you posted here. I'm wondering if we can modify other builds and get the same result? LOL I'm getting ahead of myself I can't even get the Android build Darren posted in this thread to boot!

I'm off to try again - and hopefully come back with positive results
[HD2 Android SD Development] darrengladysz:
Hi Tigerlocc,

Edit: I tried the ext 2, 3 and 4 (even linux swap etc.) the day I got wpy working and before posting this tutorial and was pulling my hair out to find a solution until I found one posted on xda and decided to post this tutorial.

For your problems, format your drive with fat 32 and 64 kb sectors. Then copy the build I posted. Don't forget to apply the update on the posted build.

Edit: Method in link for superram sense does not work
[HD2 Android SD Development] tigerlocc:
Oh snap was I supposed to apply the update? No wonder lol. I'll have to keep trying - yeah that SuperRam build is very enticing isn't it? haha
[HD2 Android SD Development] tigerlocc:
Alright the outcome is not looking good for me at the moment. I'm getting different results with different Android builds - but it always concludes in 1 of 2 ways by either hanging on the htc bootscreen, or not even leaving magldr at all after 123456 GO GO GO.

I've retried the desire_z build at least 5 times now, I've reformatted the fat32 portion of my sd card once (maybe i should try again?) and have even gone as far as to try 3 or 4 other versions of Android. Still no go - I'll keep searching and browsing for solutions. Will keep you guys posted
[HD2 Android SD Development] darrengladysz:
I don't understand what may be your problem.

Can you read your sd in windows?

Look at this thread as well for work around on builds:

It seems that you need to add nand_init as per 1st post. Got some problems with this as everything booted and worked mobile network did not work :(

i have only one sd-card adapter so i can't mount both cards at the same time. is this necessary ? so i'm tryin now to handle thiw with dd from http://www.chrysocome.net/dd.

[HD2 Android SD Development] tigerlocc:
Yeah I know it's a little odd. I'll keep trying - can't give up yet! :D

Oh so that workaround does work? Did you try adjusting your APN settings for the mobile network issue?

A few questions:

Okay so after that I have 13Gb's unallocated space and 16Gb of space for WP7 set as primary...

For the 13Gb does it need to be primary or logical? Theres no option in EaseUS for cluster size when selecting Fat32...

Furthermore theres no option for Fat16 so I'm gunna try going without WP7 is booting fine already.
