The problem is that we only have a few SD roms working. And for example DL DesireZ v2.1 works, but DL DesireZ v2.2, which is newer and just lauched, doesn't work, the support is gone :(

And we don't have as much roms as we had to choose in the past. I am trying to use WP7, to see if it is a viable alternative to my daily use, but I don't want to give up Android. Since we can't have WP7 and AD Nand at the same time, SD is the only alternative, and we have to get whatever is working instead of a lot of good builds like we have in Nand now.

If the devs start to make more sd builds closer to the Nand ones (same kernels and modules, which they can do now, since they will all be using the same hardware startup MAGLDR) we would have a lot of alternatives too.

Like I said, one of the best roms we ever had, tytung NexusHD2 froyo, doesn't work.

Santroph.

P.S: I'm willing to help any dev that need help. I'm a developer too, but a software one, not a cooker :)

I'm not a dev but I try to get it :D...I took 4GB sd and booted wp7, connect sd via usb reader to pc, copied the wp7 filesystem to my 16gb sd card...wp7 says I got 3.5GB disk space ^^...means: wp7 uses 3.5GB, 11,5GB free sd space ;). formatted other partition as fat32, but windows7 didn't find it. Now I'm trying around to get it working ;)...will post news

EDIT: WP7 got 3.5GB disk space, now booting MDJ Froyo HD 4.6 from sd card ;)...So I got WP7/ Android dualboot :D:D
[HD2 Android Q&A, Help & Troubleshooting and Genera] simonary:
I succeed to flash WP7 rom without SD card inserted. Inserting back the SD card after installation shows that SD storge with full size(not under WP7) and SD android rom (DL DesireZ v2.1) works fine with MAGLDR 1.12. Booting WP7 again will not destroy it, too. This may be a temporary method, while the free space left in WP7 becomes around 130MB which may not satisfy many demands :(.

This could be the best way to do things...

Can you please make a kind of Tutorial?

I understood what you said, and I can probably replicate it (surely will try) but some people would be really glad to have a tutorial.

I have a single problem with your approach, my biggest card, the 16gb one, was the one used for WP7, so I will have to reformat, and since I already got my WP7 working with marketplace and activated, I don't want to mess with it.

If I only had used the 8gb or 2gb card, I would be able to do it.... :(

Santroph.
[HD2 Android Q&A, Help & Troubleshooting and Genera] santroph:
The best way to know how to do this, would be to have a HD2 that has not a fully working copy of WP7, so we can test it as much as we can.

The biggest problem for me now, is that I don't have how to make a backup of my WP7 installation, or else I would do it and make a tutorial on how to use the dual boot.

Even with the option of using only one card, the SD rom version must be compatible, which in the present time, they are not (most of them).

[HD2 Android Q&A, Help & Troubleshooting and Genera] mstrk242:
The only way most sd builds will boot out of magldr, currently, is if you manually edit the initrc on the build. Backup your old init first, and keep in mind that if the init requires cpio, (cedesmith's and ram builds mostly), then this method won't work.

Edit your initrc on the sdbuild you want to run from magldr.

Look for the line that's similar to:

service ril-daemon /system/bin/rild -l /system/lib/libhtc_ril_wrapper.so -- -d /dev/smd0

(might vary depending on the build)

add nand_init at the end of it.

so it'll look something like this:

service ril-daemon /system/bin/rild -l /system/lib/libhtc_ril_wrapper.so -- -d /dev/smd0 nand_init

If you have a newer version of the ril-wrapper, you can also add rmnet_mode after, which should let you run rmnet.

So unzip the initrd.gz, edit the initrc inside, re g-zip it, drop it in the sd folder you're booting off, and you should be good. (*Again, this won't work on all builds, experiment for yourselves.)

[HD2 Android Q&A, Help & Troubleshooting and Genera] HD2_addict:
Could this work?

Here's a little trick that I used to use on my PC.

The Windows-XP installation procedure of my PC had the nasty habit of turning the entire hard disk into one big partition. There were no other options available. I remember that the IT vendor called it user friendliness, I prefer to call it stupid.

Using partition software, I turned part of the hard disk into a partition that Windows XP couldn't recognize. When I installed Windows It tossed that partition aside, took what was left of the hard disk and turned it in an NTFS partition. I wonder if the same trick could be used on an SD card.

- Turn part of the SD card into an unknown partition.

- When you install WP7 it will hopefully discard the unknown partition, use what's left of the SD card and do it's own thing with it.

- Reformat the unknown partition to a FAT32 partition and copy your Android files to it.
[HD2 Android Q&A, Help & Troubleshooting and Genera] futureshock:
i think not... wph7 is here to use the entire space...

on thing i read anywhere is that when the phone founds a partition allready that it canuse... it wont reformat...

in the tut thread i called for someone who could try this (format a part of the sd with exfat) i cant because my 2nd sd card is not recognized in wph7 ....

have to buy an 16gb sdhc card in a few hours!
[HD2 Android Q&A, Help & Troubleshooting and Genera] HD2_addict:
"on thing i read anywhere is that when the phone founds a partition allready that it canuse... it wont reformat..."

By unknown partition, I mean any partition formated with a filesystem unknown to Windows (Linux EXT,EXT2,...). Wp7 can't use those partitions because it simply doesn't understand the filesystems. As far as WP7 is concerned, those partitions might as well not be there.

If I am correct then only the MAGLDR bootloader needs to see the partition, not WP7. Haret is no longer needed.
[HD2 Android Q&A, Help & Troubleshooting and Genera] santroph:
It doesn't matter what kind of partition does exists in the card in the first boot.

WP7 does erase EVERY partition in it's first boot with a card and formatting a whole card with its partition.

So your option doesn't work with how WP7 function.

The only option will be to use the way the other user showed us, with a smaller card and a bigger one, getting the smaller WP7 created partition and puting it on the bigger one, with a new fat32 partition.

I promised to do a video tutorial, and will, the thing is that I can't right now, only in a couple of days.

[HD2 Android Q&A, Help & Troubleshooting and Genera] santroph:
One thing that I'm looking is that the thread is kinda of going a different way.

I would like to tell you all again that the thread asks for SD version that can be booted with MAGLDR SD option.

Those roms could be used to Dual boot WP7/SD Android OR Nand Android/ SD Android :)

Of course a WP7/SD Android in the same card IS a important deal in itself, BUT this thread is, in its most important factor, to call the attention of the devs for a MAGLDR SD compatible version.

That said, let's try to find bootable versions of SD Roms.

The DL v 2.2 and 2.1 are already said to be working, I still haven't found any other easily bootable rom.

Just tell us how you did it, it was with the copy partition way?

I must say I droped Wp7 as I think this version is WAY limited for people outside of US/Europe right now, and since I'm from Brasil, the system doesn't give me a rest in several ocasions: Zune doesn't work right, I can only sync from pc, not download from phone itself like the Zune player. I can't have portuguese in keyboard, not even some chars, I can't do several stuff, and since this is the first version I can wait for a new one.

I still would like the chefs to give us some new SD version, so Nand Android, and SD Android can coexist :)

You can't flash wm6.5 with magldr, and its not possible to have 2 os's flash to nand at once yet.... but cotulla is working on a wm6.5 build that can be booted from sd card with magldr. But for now, if you want wm6.5, you have to leave it on nand and boot android with haret.

Is there anyway to get updates about this?
[HD2 Android Q&A, Help & Troubleshooting and Genera] zarathustrax:
Just wait and hope for cotulla to release it. It was a week or 2 that he posted that he was gonna try to make a sd version of wm6.5... he seemed to already have an idea of how he was gonna do it, because he even talked about how it would consist of 2 files... a .bin file that contained the os and a file which would basicly be the data file which was what winmo would read and write data to. He even said you could mount that data file from android so that you could share music or files with android. The post by him is somewhere in the magldr release thread. He didn't say that he would definitely be able to do it, but that he would try... but if anyone can do it, cotulla can, so im hopeful that it will be released eventually. Cotulla doesn't give release dates, though, so we'll just have to be patient.
[HD2 Android Q&A, Help & Troubleshooting and Genera] abima80:
im imagining that our phone is like pc, we can have multiple OS like windows and linux, maybe we can use the same concept like pc, all the OS runs from hard drive (sd card) so that all the ram or rom can utilize the memory space to run the OS, its like entering magldr same like entering dos.

Contrary to popular belief, I think you actually need 3 partitions. 1 for WP7, 1 for Droid, and 1 for Droid data. I have 2 partitions on my card and it runs like dirt.
[HD2 Android Q&A, Help & Troubleshooting and Genera] zarathustrax:
You only need 2 partitions... one for android and one for wp7. If wp7 is running bad for you, it's probably because of your sd.

Some sd android builds... well, 1 or 2 sd builds can use extra ext3 and linuxswap partitions, so you would have 4 partitions with wp7. Only AmericanAndroid and I think dandiest's DesireZ builds can use these extra partitions... but they are not needed.

Are you trying to run good 3d games like NOVA, NFS Shift, Gameloft HD games on your galaxy 3 and when you ran them you only saw beatiful white textures on the screen and then started to abuse your phone's GPU. Actually you are there isnt any problem with galaxy 3's hardware it can run all the gameloft HD titles without any lag.

You can see on the youtube that a phone (crap) like LG GT540 Optimus can run gameloft HD games. It has only 600mhz processor and 156 mb RAM and not a very powerful GPU.

The actual problem with galaxy 3 is that its opengl drivers cant render 32-bit graphics and are replaced by white ones. It is probably possible it get its opengl drivers get updated after it gets official froyo update or it also possible if some developers finds way to put drivers in the phone.

i5800 have a Samsung S5P6422 with 667MHz clock, 256MB RAM

The CPU itself is the same(ARM1176JZF-S). Only differences at tech - our's is 45nm, Spica is 65nm.

And at all - our processor is cutted version(DMA channels, GPU, etc) of Spica's.

No, you can see here the complete spec, not just MHz: http://pdadb.net/index.php?m=specs&id=2582&view=1&c=samsung_gt-i5510

CPU: Samsung S3C6410 downclocked to 667, then "Browse devices based on S3C6410" or http://pdadb.net/index.php?m=pdamaster&posted=1&cpu=a6410

And see devices...

"It neither has i5700 cpu (if you know i5700 wasnt able to run proper 3d games even worse than i5800 "

No it's the i5700 CPU, and can run 3D games with PROPER DRIVERS, which in Spica's case missing that's why i5700 can't run 3D games.

I5800 will never run any 3D game, because doesn't have the hardware to render it (ok you can play laggy white textures if it's enough for you).
[Galaxy 3 General] apoorv28:
I thank Szaby59 for taking interest in the thread. Now lets just gets rid off that i5510 (I have already tried my hands on it it has a slower UI than g3 and it has only 256 mb RAM not 512 mb as listed in your link but I am not sure about its CPU) topic it has gpu or not it dosent matters to us. We should think about galaxy 3. I actually a very big gamer yet I am in 9th grade only and have more than five years of extreme gaming experience. I am one of those guys who cant live without gaming even for 3 hrs. When I saw gameloft launching HD games for android I thought they would be supported on all android phones and resulted buying this crap. I already knew g3 had a bad gpu but my parents wont buy me a better phone.

Lets get down to the topic - Although g3 had problems with gpu I tried running some real 3d games on it and some of them even worked like raging thunder 2. Many people have problem running it on g3 and phones better than it. People usually see white textures on it but it ran it with full speed without any texture problem ( I going to upload its gameplay on youtube and paste its link here by tomorrow). Fifa 10 also worked on phone with only the texture of the field missing and rest of the details were ossom and the gameplay didnt lag. So after a plenty of research concluded that maybe the opengl drivers have problem rendering 32 bit textures just like spica. If there would have been a gpu problem rt2 wouldnt have ran so beautifully. So according to many people if its the gpu is weak then why does rt2 works on the phone? Please answer it.
[Galaxy 3 General] Szaby59:
What does it mean 'working' for you?

For me: good framerate, minimally 25 FPS, and correct textures.

In RG2 the whole car is a big white texture and lags.

If you wan't play some good game download angry birds or Sega Genesis Emulator and play old classics.

HD games maybe work, if the game doesn't require 3D accelarator.
