[Q] Android and WP7 Dual Boot

With the recent developments of Android and WP7 for the HD2, I really can't decide between the two. Will there be an option of dual boot like with WM6.5? I'd love to have this option.

I would definitely love for this to happen, although WP7 is in the lead for me now, booting android once in a while wont be so bad.

i think itz possible in tmobile usa HD2 with itz 1gb ROM ... two partitions using two NAND OS... dual NAND..

I'm very interested in this option. Hopefully this will be available soon.

I hoppe we find a solution for Leo from EU (512Mo).
Like WIN6.5 + Android on SD ?
My favorite way : Android in NAND, WP7 on SD !!

think we should be able to still boot android off sd with magldr... we just need to switch to a different sd card that wasn't used with wp7. I hope its possible. will be trying it soon.

i would love to do this, i have a 124 leo.

F*ck the 512!
Android+WP7 would be sweeeet for 1024!

im still running an old build of sd, so is it possible to upgrade radio, magldr, win7 nand and keep android on sd?
im not really wanting to give up android just yet, but i do admit i want to see what win7 is like

based by the link above (with google translate), its possible to dual boot with wp7 nand and android sd

Is it possible to back up a android nand rom, so i don't need to download al apps again and set them all up again?

But since your lazy, yes there is. Its called Titanium backup and it saves all your apps and settings into a file. When you install a new build just recover that file from within Titanium backup and all your apps and stuff will be there.

So...does anyone here speak enough Chinese to make more sense of this than Google Translate does? I think some sort of modification needs to be made to init.rc. Possibly system.img too. It's also not clear to me if a NAND or SD ROM is meant to be used. There are some links which I'm trying to make sense of...

Im unsure on how to do this also, if anybody fancys typing it into something we could follow it would be great!
Im in work today and my phone is fully charged ready for win7/android combo

How would you boot android from nand if you can't access the file system of the SD card?
Its an unknown format and magldr surely won't be able to boot anything from it.
Maybe it works the other way round, though?
Or you could use your phone7 without sd card...
hey that may even work.
Limited storage for phone7 - who cares?

That's what I would like to be able to do. WP7 is nice to play with at this stage but I still plan to use Android most of the time.

Half of the sdcard is formatted in FAT32. The other in WP7 system file.

Here's that thread translated:

I have already declared in the title dual boot, or have friends do not understand the altar. After the following modifications, select the boot wph start guide wp7, select the boot ad sd sd boot on Android , Android WP7 and dual-boot, the boot options can, without disturbing each other. Start wp7 will not interfere with sd card, wp7 sd card did not even know exist, the question is wp7 little space available, but at least can be used.
Expect experts to address the first time in wp7 can choose to start the occupation of the sd card space, do not fully occupied enough.

Thank DFT ! Because SD Android running well, I have not brush Nand Android, waiting for the arrival of WP7.
Today, DFT has released long-awaited HD2 users WP7, I finally started to brush. Brush some of the altar before the access to the Friends of the experience, that really exclusive WP7 SD card, which can later how to run Android.
I have access to the information carefully and found that the SD card as WP7 only system expansion space, the first start of the SD card partition to use. Therefore, I decided to removed the SD card so reserved for Android use.
PC: Windows 7
HD2: SHPL 2.08
SD: Sandisk 8G c4 (from the phone in the show)
The following is the process of Brush:
1. Three-color screen brush Magldr 112 (all normal, NES Set )
2.Magldr start to select the USB Flasher, PC-side DWI (all normal)
3. Phone reboots directly into the WP7, simple to use, after all the normal (free space 98M)
4. Handset off
5. Insert SD card
6. boot holding down the hold button, enter the Magldr menu
7. Set always shows the menu (to decide, because I want to dual-boot often, so set the boot menu)
8. Set the boot path SD card Android
9. Guide the SD Android, the show finished HTC interface (kernel, Init after) boot into Andoird animation between the phone restart
Episode: I stupid out, SD card, there are a lot of information not backed up, hands and no card reader, can not enter the Andoird, the backup can not, WP7, when not installed into the SD card, do not expect him to. Fortunately, there are menu items that Magldr USB storage (my first use of Magldr), select this option, the memory card sorting.Remove the SD card all the Android-generated directory (the directory is generated Android, do not also delete a Android), re-boot, the first screen to enter Andoird die.
10. Online access to information, Magldr guide SD card Android, need to modify inti.rc.
11. Will system.img (I use the DHD Android) copied to the Linux modified.
In the service ril-daemon / system / bin / rild-l / system / lib / libhtc_ril_wrapper.so append --d / dev/smd0 nand parameters, to support
Nand boot.
12. Returns Android phone, after a successful boot.
Nagging: WP7 egg really hurt, WIFI without any settings, I have been using a static IP, can not be set.

He's dual booting, but none of the SD card space is for WP7. It only has around 100megs left. WP7 automatically RAID0's the whole card with internal memory for space. That's why removing the card screws up WP7 and a hard reset has to be done. I think what would be ideal is if the card could be split into 8gb for WP7 and 8GB for Android, but part of the problem is you can't call HARET.exe or CLRCAD.exe because there is no OS to understand those executables.

[Q] DualBoot Wp7 and android?

Just Installed Windows Phone 7 on my HD2 and I was wondering if there's a way to Dual boot Windows phone 7 and Android Either SD builds or NAND builds.
Thanks in advance

Can you not run Haret or whatever other android loader you have from your wp7 file explorer? P.S. I haven't installed WP7 yet, I need to know if Dual Boot is possible

I can't even find a file explorer
so far I like really the looks of WinPhone 7 but I miss the Functionality

There is a guide for this under the android dev forums, its one of the stickies.

You can still run android from SD with magldr... you just have to either partition your sd card or switch sd cards used for wp7 and android. WP7 doesn't run winmo apps. And doesn't come with file explorer, but schaps made a file explorer called touchexplorer that you can install. Read around the forums, there are directions allover for this stuff. I have WP7 on my nand right now with a 16gb card, and I'm about to setup my 32gb card to run android off of.

Thanx, so I have an 8 GB card and i'm Currently runing WinPhone 7
I don't Know exactly how to partition it and the method to run android too is there a guide?
and will it be NAND or SD build?
and if both of them run will Both OS's be able to see same Music, Photos, etc.

http://forum.xda-developers.com/showthread.php?t=913815
Here's a guide.
And no, they won't be able to see same music or anything... they will be completely seperate partitions and can't read each other. WP7 will be on NAND and Android is ran from SD card.

Thank u so much
just another Question plz
Android can't be run from NAND also as a second operating system, it must be an sdcard build right?
Edit: Ignore that found the answer in the thread which is no it must be ran from SD
Thanx again

Windows Phone 7 from SD card or Android/ WP7 Hybrid ROM?

I was wondering if it would be possible to either Boot Windows Phone 7 through MAGLDR from the SD Card like you can Android by maybe partitioning the SD Card so it cn have it's own space?
Or a more realistic option which would be to have a NAND ROM that includes both Android and WP7 installed to the NAND and partition the SD card for storage? This second option I believe could be possible if the NAND is partitioned correctly to allow them both to run and then you could select them in the MAGLDR!
I would like some dev feedback on this as I would try building a ROM myself but I don't know the workings of the partitioning system in MAGLDR well enough to try!
Thanks in Advance for any help!

I've seen that but what I want is to boot Android and WP7 from NAND NOT run android from the SD Card like that guy done because that makes android run slow and I want android as my primary OS!

I run Android from SD as my primairy OS, WP7 is on NAND just to play with and test it. I tried Android on NAND, but to me it wasn't noticably faster then when running from SD.

Snap I'm using sd build of Android from magldr and it runs fine even boots ok, there might be a little lag when doing something the first time but other than that its great

Well the thing is I like to use a fully fledged Desire HD ROM and it's stupidly slow from the SD card... my current build is squashfs'd so only takes up about 200mb for the actual OS and I'm sure WP7 could be fitted in the rest of the space and like I'm doing now I can use EXT4 on the sd for data! Now what's needed is if someone can build a hybrid ROM!

Hi, anyone can share how to u do this ? is it through the method that uses 2 sd cards during the formatting stage ?
Btw, what if i dont mind swapping sd cards for diff os ? Can this be done and how ? I tried to insert another sd card which I previously use for my android sd build, tried the sd boot , it gave an error of sd kernel . anyone can advise ?
Thanks !!

[Q] SD Card mode from NAND mode

Hello All....
I have installed android on my HD2, via NAND, and found that i suddenly ran out of space, and i cant install any apps. This is obviously due to a large rom, loaded onto the phone. I therefore started invetigating android via SD card. What should i do as precaution not to brick, or where can i find a guide to going to sd method from the NAND method.
Or alternatively, if you can help me with my partition sizes, for when i reflash android that i actually have some space. If someone can give me a breakdown of what the partitions must look like...
while this may be easy for others, i am a noob on the hd2-android..
a Speedy response would be highly appreciated...
thanks

Here is a decent walk-through on how to dual boot with Windows Phone 7 (with WP7 being on NAND and Android being on SD). He covers pretty well the partitioning processes that are needed. I haven't tried it out myself, cause my HD2 is being shipped to me currently.

You don't have to partition your card for most SD roms. If the Rom requires partitioning it will tell you in the instructions. You can boot SD roms through magdlr as well. Just copy root folder of Rom ("Android") to root of SD, then in magdlr go to services>SD boot settings and ensure it is pointed at you Android directory. Then select ad sd boot and it should boot from there.
P.S. If you intend to keep your nand install, you will need to rename your Android sd folder to something other than Android. Be sure to change the directory in magdlr to match the new name of your folder. This worked for me. I am currently running a nand build and a sd build and both run great.
Cheers

Android on NAND and also on SD?

Part of the beauty of having WP7 on NAND and Android on SD is that you can have as many Android ROMs as you can fit on your card and you can boot into any of them as you please. But say I want to install Android on NAND. Can I still be able to have that one Android ROM on NAND, but multiple other Android ROM's on SD?
Simple... If I want to be able to boot into more than one OS, must I have WP7 on NAND? If so, is there any guide for this? I cannot find one in the main sticky.

Good question, It would be good if you could switch and chang based on mood.

You can have Android on NAND and as many sd builds as you want, same as with WP7. Until my HD2 broke a few days ago, thats just what II did, a DHD build, a MIUI build, and a CM7 build on sd, with UD on NAND. Just have to choose your AD SD directory in magldr's 'services', and then boot AD SD.

I do not think you can due to the fact that you have to run the HARET program. It only runs under Windows Mobile as Android does not run .EXE files.

Yes you definitely can. Check my sig

Well, I saw several builds in the NAND Android forum that specify they support MAGLDR. No need for haret. Here's some of them: LeoRCMix, JW MIUI, HardDroid2. So I didn't think that was a limitation.

How do you partition your card for this setup? Is there a guide somewhere you can link here please? Or is it the same procedure you use to partition your card when you're running WP7 on NAND and Android on SD (which I've followed before)?

Any advise whether NAND build or SD build is better? In terms of performance I mean.

NAND builds will usually be faster.

As far as partitioning your card, with Android it's not necessary, you can do everything on a single Fat32 partition, unless you want to use A2SD then you'll want a single (primary) Fat32 and a single (primary) ext3 or ext4 partition for your apps/dalvik-cache. I recommend using DarkTremor's A2SD script with your NAND ROM, and if you use the DHD build in my sig, then it will automatically detect your ext3 and you'll automatically have the installed apps from your NAND on your sd build.

sd android builds for magldr will work if you have another android in nand,but the kernel for sd build must not be a nand kernel.for example if you have a sense build in nand and you go to start from sd a build that has tytung r10 or rafpigna kernel the kernel will start but for some strange reason it will load the nand build and not the sd build.then if you go to settings you`ll see that the kernel is changed and you have error wifi because of different kernel modules.this at least happens to me,every time i tried to start a magldr sd build with another android in nand.at first times i thought that i was pushing wrong button on magldr

Great advise, guys. I'm going to play with this soon. Thank you!
