[HD2 Android SD Development] shree.cse:
I don't think so. I have an 8gb transcend class 2 stock SD card. I partitioned it with 3.5gb for windows7 and the rest of fat32 for Android. When ever I booted into Android and restarted to wp7, I am loosening all my settings. But not the hard reset, O am sure. And now my Memory status in wp7 is 15mb only, before it must be around 2.6gb

May something is causing SD card to be corrupted!

This is my whole problem

Now I am back to nand Android of imilka's glacier sense. Happy with this and stick with this till I can found a solution for this SD card partition problem
[HD2 Android SD Development] shree.cse:
I tested that, but freezed at HTC black boot screen. Any way, I am now on Nand Android

Thank-you

I am trying this with Copes AOSP SD build, which I've put in /sdcard/Android/*, I've followed the instructions, set AD SD boot in Boot Settings to the Android directory, but I get stuck at GO GO GO! (Magldr 1.13), what's going on?

Here is exactly what happens:

ANDROID LOAD at 11800000
[COLOR="Lime"]from MicroSD[/COLOR]
Load zImage
K: /ANDROID/zImage
Load initrd.gz
I: /ANDROID/INITRD.GZ
[K]11808000:31FA4C [I]12200000:1D0137
Load done!

GO GO GO!

At which point nothing at all, does in fact GO.

Since many days i'm trying to get darkstone's SuperRam 1.5 (of course without Sense) to boot from SD-Card using Magldr 1.13. This android version is the most stable, fastest, smoothest and closest to stock Android version 2.2.1 i've ever had on the HD2 !!!

But i don't know how to get this fabulous build to load. There is a download-link for darkstones SuperRam, but with Sense and that's useless, because damn slow.

Could anyone give me a hint?

!Desparate Houseman! :-(
[HD2 Android SD Development] popab:
Yes,you can boot Android from SD,and have WP7 as your primary rom.
[HD2 Android SD Development] Bobby9:
Yes, I know this well ! Could you dive into detail and tell me how to edit the initrd.gz/initrd/init.rc file behind the /dev/smd0 with the obligatory "nand_init" text on a debian Linux-System with all this gunzip and gzip commands - that's what would help me... (see first post on page 1)

Darkstone's build and a corrected initrd.gz (sync-problem) can be found here:

http://xdaforums.com/showthread.php?t=870518

The best initrd which boots with haret.exe is right here:

http://www.mediafire.com/?ebwijry3m9k6p3u

Or can somebody edit this for us to boot with magldr AD SD?

the letama edited ROM (see page 1) is unfortunatly with sense and useless, because very slow and it judders like hell.
[HD2 Android SD Development] zarathustrax:
The tmous hd2 has same ram as euro hd2s and any sd android build will work on both. Only difference is rom size, and sd builds don't touch the rom.
[HD2 Android SD Development] Bobby9:
with haret: yes, you're right (the fastest is darkstone SuperRAM 1.5 without sense)

with magldr: will NOT. Will freeze to death while booting.

Some guys don't understand the difference between haret and magldr booting. Never mind...

What version (link) is working with MAGLDR ?? All booting but frezee

I tryed:

- SuperRAM_FroYo_V1.5

- NexusHD2-FRG83D_V1.8_(Froyo 2.2.1)

- Motoman234_Desire_PCB_Sense_V1.0

- Core_Droid_HD_V0.4_Release_Version

all this booting but freze :(
[HD2 Android SD Development] zarathustrax:
It makes no difference if you have a tmous hd2 or a euro hd2... haret and magldr booting work the same on both. How is magldr different on a tmous hd2 and a euro hd2... if you can boot a sd build on one, you can boot it on another. The edited sd builds I have given to people have worked fine on both versions. I completely understand the difference between haret and magldr booting.

And I have DS Superram 1.5 booting with magldr fine now with letama edited initrd.gz. It just freezes the first couple times you boot, but after you get it going, it boots everytime fine.

EDIT: I notice the link on post1 goes to sense ram build... I have posted the correct edited initrd.gz that letama posted. I have also modified many other builds to work and have gotten almost every build I've tried to work. If there's another build you want, just pm me.
[HD2 Android SD Development] Bobby9:
Wow! Thank you, zarathustrax! darkstone's SuperRAM 1.5 without sense ist booting with magldr from sdcard without any problems now! Very fast. You've done a great job, zarathustrax!

Thanks again from Germany, Bobby
[HD2 Android SD Development] Bobby9:
1. Download darkstone's SuperRAM 1.5 from Dec.18th, 2010

(the fastest, stable, stock Android 2.2.1 without the consuming Sense = small, clean & bloody fast)

2. Get the initrd.gz file from zarathustrax in post # 223 on this page and copy it into your android folder on sdcard

3. boot AD SD with magldr and smile :-)

EDIT: some off-topic-tipps:

- format the FAT32 part of your SD-card using Windows-Explorer with cluster-size set to "standard". This will speed up your SD AD and not destroy WP7 partition.

- flash radio 2.10.50.28_2 AFTER you are finished with WP7+Android installation (unplug USB-cable, power off, hold volume down, power on while holding down volume, wait for coloured screen displaying "Serial", plug in USB, then flash radio). This will help you to have as less as 3 mAh power consumption in standby and ~100 mAh less while in use.

- disable 'Use wireless networks' in Settings>Location menu. You will now get 7mA or less constantly. darkstone discovered this as the main culprit. Also works in other builds.

More tipps welcome

can u help me initrd.gz from [Build] PSFreedom , problem is it boot load and when to start phone reboots
[HD2 Android SD Development] ricola7:
EDIT: works now, don't know why...just booted it up a couple of times...strange stuff

Thx for the tipp...I can't get it to work though ;)

I took the Darkstone build from Dez 18th, exchanged the initrd.gz with the one zara posted...

It boots up fine, but when it finally displays the android lock screen, it instantly freezes (no touch response whatsoever)

I used a formatted sd card (which works well for other builds booted from magldr)...Don't know whats the prob...

Greetz Dom
[HD2 Android SD Development] zarathustrax:
Yeah, sometimes it takes a couple times to fully boot up, but once it does, it should work everytime after that. It took me 3 boots before it fully went through setup.

I'll take a look at that build and see if I can get it to work... probably just need to edit the init.rc file.

Desire HD2 Build

FYI

After some reading and research (I'm not familiar with unix systems) I managed to get my favourite SD Build running.

HOWTO:

-- download the Desire HD2 rom

-- browse into updates\init-files\ folder

-- there you can find the init.rc file

-- overwrite the service ril-deamon line with the one mentioned in the first post

-- finish

no need for mounting the system.img or download the linked file from the first post.

this was all I have to do to get this build running.

BTW: I tried to install also the updates, but one of them crashed my build, so be carefully. I don't know exactly which one was the problem cause I tried to install it in one boot cycle. At the moment I use the build without the updates and every thing is working as far as I can see. :-)

[HD2 Android SD Development] hlpdt10:
i installed wp7 to my HD2 Nand and i want to install more android rom to my sd card ( i used "two sd card" method to install wp7 and android rom in my 8gb sd card). I was sucessfully install some android rom to my sd card (ex: Future stock rom, desire_z..) but now

i have a problem:

i'm using a Gizmo drive to mount system.ext2 of rom "[6 Feb][DL DesireZ v3.4 final][DL Data2SD/Ext4 v2.7][Nand/SD/MAGLAR]" (to edit the init.rc file)

but after mounted i can't edit the init.rc file inside the drive. ( i have already installed all driver and sofware for reading ext2/ext3 file) i can only read the ext2 file and copy init.rc file from ext2. please help me:

- may be the system.ext2 has been locked??

- How can i edit the init.rc file inside the "read only" system.ext2?
[HD2 Android SD Development] hyellow:
have you tried... right clicking on it?
[HD2 Android SD Development] hlpdt10:
yes..i already did right click but i still can't edit the init.rc. I can copy it to my desktop and can edit the init.rc in my desktop but after that i can't replace the init.rc in system.ext2
[HD2 Android SD Development] zarathustrax:
Are you using a microSD to SD converter to edit the microsd? I had the problem using that before because I accidently had to lock switch set to lock on sd card. Or maybe copy the whole system.ext2 file to desktop, then replace init.rc, then put system.ext2 back.
[HD2 Android SD Development] ricola7:
Hey,

what you can try is following (even though you already installed the ext2 drivers):

1. restart your pc and don't open up gizmo yet (must not be in autstart either)

2. Go to this page http://www.fs-driver.org/download.html and download the file.

3. install it on your pc (if you have windows 7, run it in vista compatiblity mode)

4. you can abort the installation when you are asked to designate partitions, the drivers are already istalled at this point)

5. open gizmo and mount the ext2 file. maybe you can edit the file now via right click
[HD2 Android SD Development] ricola7:
Hey guys,

any experienced linux users who can help me?

I installed an ubuntu virtual machine a few days ago to edit the init.rc files located inside the initrd.gz archives. This works perfectly...

Now I would also like to edit the init.rc files inside the system.ext2 files/partitions.

Is it possible using ubuntu to acces system.ext2 and edit the files inside? (I can access and edit using gizmo under windows, but I would like to do it with ubuntu too)

And if its possible I would need the commands for the terminal...

Thx.

Greetz Dom
[HD2 Android SD Development] hlpdt10:
yes. i'm using "micro to SD converter" to edit the microsd, but i'm using a tape to keep the lock off on my sd card before i inserted it to my mac. ( by the way, i'm using vitual w7 on my mac). I already coppied system.ext2 to my desktop and edit from that but i still can't do. I'm afraid the problem may be is: i'm using vitual w7 inside mac ( so it hasn't got enough driver, i had some problems when i uprom by vitual w7 in mac, i have to using another lap to up)

Can any one can edit the system.etx2 in side mac?

Yes. I already installed all the driver i need. :(
[HD2 Android SD Development] ricola7:
i can upload the edited system.ext2 if you want...but tomorrow, I'm tired now...

Is it even necessary to edit the init.rc in system.ext2 too? Cause the init.rc inside initrd.gz is already edited and as far as I know this build is magldr ready?!
[HD2 Android SD Development] hlpdt10:
hehe..Finally i find the way to mount ext2 in mac and in ubuntu too for editing it. :D

and
[HD2 Android SD Development] zarathustrax:
What builds do you have to edit initrd.gz files for? Only builds I know of that needed those files edited were Darkstones RAM builds, and letamam has released edited initrd.gz files for both of those builds already. Every other build I have gotten working by just mounting the system.ext2 or rootfs.img.

[HD2 Android SD Development] ricola7:
THX DUDE!

You saved me! I had to add "sudo" at the beginning of the line though (if some others want to try this too)

Glad you got it to work in windows (or mac ;)) too.
[HD2 Android SD Development] ricola7:
I only edited the initrd.gz files for the Darkstone RAM build (wo sense) and for "MDJ Gingerbread 1.0 rc5". I noticed too late, that I could've used letama's initrd.gz atleast for the Darkstone wo sense ...maybe this would've worked for MDJ too... But I like to play around and it drove me crazy that at first I just couldn't get my edited initrd.gz to work. And after that hassle it's sooo sweet if you finally get it going ;)

And regarding the system.ext2...I didn't even notice before that there is an init.rc inside too. I thought there is only one iniside the whole build, and when I found the init.rc in the initrd.gz I thought that is the way to go...I learn alot in this thread *lol*
[HD2 Android SD Development] sallal:
hey,

i made a modified initrd.gz for a Gingerbread 2.3 Build

Original Build:

Modification can be found in the attachments.

just unpack it and replace the initrd.gz it with the original one you find in the android folder, and start living out gingerbread :)

cheers

sallal

EDIT: Ok , i tried it out now in quite all issues a phone should work like and have to say -- it has a lot of bugs. i dont know if that is from the developer himself or through my editing, but i advise NOT TO USE THIS VERSION.
[HD2 Android SD Development] zarathustrax:
Isn't that build already have modified files in it to use with magldr? All of Cope and Warrens prior versions did, so I don't know why that wouldn't. Also, you only have to modify the initrd.gz if there is no system.ext2 or rootfs.img with an init.rc file in it... only builds I'm aware of that need edited initrd.gz file is Darkstones 2 RAM builds.

EDIT: I just downloaded that build to test, and like I said, there's already a folder in the build called SDMAGLDR and it contains the rootfs.img that you replace to boot with magldr. That build doesn't need the initrd.gz file edited, so that is probably what caused all those bugs.
[HD2 Android SD Development] sallal:
nah my friend, i tried it out already, and there are the same bugs ...

i think this wont get me to cope... back to (/edit: mdj) Froyo then.

[HD2 Android SD Development] zarathustrax:
You must have left your wp7 partition as logical. Use minitool partition magic to change wp7 partition from logical to primary... right click partition and there is option to change to primary. You may have to hit apply. After it's primary, android will mount sd card fine.

[HD2 Android SD Development] somebully:
Will this work OK with the stock WM 6.5 ? I see OP keep refering to WM 7.. I'd like to have WM 6.5 (NAND) and darkstone SuperRAM run from SD..

I dont use WM 6.5 but for "emergency" I'd like to have a OS that I can trust (no matter how stupid that might sound with WM 6.5)
[HD2 Android SD Development] zarathustrax:
This thread is about editing sd builds to run with magldr for people dualbooting wp7. To keep WM6.5 is not stupid... I would have WM6.5 on my phone if I didn't have WP7.... I love the ability to run 2 OS's on my phone. I would rather make use of the unique ability of my device to dualboot than flash android to NAND and make my HD2 into just another android phone, which is nothing special. Dualbooting WM6.5 or WP7 with android on the SD card makes my HD2 able to do things no other phone can! Getting rid of the dualboot ability makes it so the HD2 can't do anything that many other android phones can't do as good or better. Winmo is a great OS, too. Hopefully a SD version of wm65 will come out soon so I can tri-boot WP7, Android, and WM6.5.

Anyways, back to the point... you don't have to do anything special to run builds with WM6.5. You don't use magldr... you use haret.exe from within winmo to boot android. Builds only needed to be edited to be able to run them from magldr. With winmo, most builds are already setup to boot correctly.
[HD2 Android SD Development] somebully:
Thanks, I already run Android SD build with haret.exe.. So magldr dual boot wm6.5 nand + android sd build (edited to support nand so all hardware is initialized) is currently possible?
[HD2 Android SD Development] somebully:
Thank you for the comprehensive reply, found every part interesting.

I think I will go for the WM7 nand solution. My only concern is that whenever something has gone wrong with my phone (running Android), I could always trust WM 6.5 for my sms/call/GPS needs.

Is GPS working 100% in WM7?
[HD2 Android SD Development] zarathustrax:
As far as I know, GPS works fine. Haven't tested it much. One big thing missing from WP7 so far is a good Turn by turn GPS navigation app. There's an app that uses online data, so you need a data plan, but there's nothing that stores map data on phone yet. I'm sure that will change soon enough... but that's why it's good to have android as backup. GPS should work good in recent android builds.

Another thing you should know before jumping into wp7 is that WP7 will format your SD and make it so only WP7 can access or see your card, so you can't take card out and use a card reader on computer to transfer files. And to dualboot android, you have to partition your SD card so WP7 gets it's own partition, and you have a fat32 partition at the beginning of the card for android. You will be able to access the fat32 partition with a card reader in your computer, but not the WP7 partition. And WP7 can't access the fat32 partition... only it's own partition... so you can't share files between the 2 OS's. It can also be a little tricky setting up partition correctly, but there's a few threads about it... a link to one good tutorial is in my signature.

Also, WP7 can be picky about what kind of SD card will work for it. Some cards won't work or will cause lag or resets or other problems. I've had good luck with class 2 and 4 sandisk cards.

One last thing about WP7 on HD2 is that you need an activation code from microsoft to get live services working and marketplace. You basicly have to call, e-mail or chat with MS customer service, and tell them you have a HD7 that is asking for activation code... some people have trouble getting codes from MS because they don't support HD2's, and they'll sometimes ask for imei from your "HD7" or proof of purchase. But most people are successful within a few tries, if not first try.

You should go to the HD2 WP7 section and do some research and make sure you know what your doing and what you have to do before just jumping in and flashing. It can be complicated setting everything up, but I think it's worth it in the end. But definitely read a lot and make sure you're comfortable about knowing what you are doing.

Would someone be so kind and edit my rootfs for me? I was unable to mount it using the Ext2 IFS driver with Virtual Clonedrive. When I mount it via clonedrive, Windows says it can't access the disk. Not sure what I'm missing, but probably my unfamiliarity with the IFS driver and how it works.
