[Q] Dual Android boot up. nand and SD

Hi Guys . Sorry if this has been asked before but i cant find it in the search. I am already using a Nand Rom on my EU HD2 . I would like to know if its possible to still have a second android rom being able to boot from the SD card ? Lets say like a Ram rom booting up from the file explorer like haret was for winmo . Thus shutting the Nand rom down and then booting from the SD.
I know something similer has been done with WM7 but i dont want to take the plunge with WM7 yet as im happy with android. Has thi sbeen done or is it possible ??
Thanks in advance.

Yes you can, you can boot NAND Android, and still use SD Android.
Hold the Power button when you start your phone, to get into MAGLDR menu.
In the Service Menu, set the boot directory to your SD's Android folder, where the zImage and initrc.gz files are.
Usually, /sdcard/android directory, but depends on build.
Then go back and select Boot SD Android, and woohoo, good to go.
Now, when you select Boot NAND AD, you boot from NAND, when you select SD AD, then you boot from SD.

Thanks life u are a star !!!

What build is recomended for this Sd or ram ?? also im getting a error message in boot up from sd it says no newinitrd and continues to reboot . Help appreciated.

Ive got another question. It is possible, or will be possible in the future, to boot Winmo from sd?
I have an app that is dedicated for Winmo only, it is a navigation app.
I would like to have Android in nand, which is much more comfortable than booting it from SD.
Is there, maybe, another way to achieve it?

Well, technically, everything is possible. Booting WP7, booting WM6.5, from SD, etc...
But... The question is, will anyone even bother?

Well, it shouldn't be looking for newinitrd.gz but initrd.gz, if that is what it is looking for, and your directory only has initrd.gz, try renaming it and see what happens. I will go try when I have free time, I probably will be busy for the next couple of days, so I will see!

Actually cotulla posted in the magldr thread that he is going to try to get a winmo build working that can boot from sd. I don't know when he plans to have it finished, or if it will even work out... but he's working on it. I also hope it happens, as I still like using winmo for certain apps... like fpsece works a lot better than psx4droid for playing playstation games.

Oh, thats good to hear.

Hi life ive tried to rename no progrees there. I think a tutorial on this would be good on this matter.
Thanks Dappa

when i try to change the boot directory its nothing but symbols. i tried rebooting back into magldr but still the same
any help?

Look like you don't know what you talking about...

would love to have android, but getting very confused!

I am new to putting android on my hd2. I've never done it before. I want to do it. But i'm getting confused with everything that needs to be done. I think i want to do the NAND way, from what i've been reading its faster and i'm not going to want to switch back and forth to winmo.
I understand that you need to have the Hard SPL, MAGLDR installed. Then pick a ROM you would like to try. I'm getting confused cause i dont understand the CWM part. It seems like it is better from the comments and posts, i guess. Do I have to use that? Also I would prefer to not mess with my sd card. I will if i have to, though. Paritions and all that worry me. ha.
I guess I just want a fully functioning android build, that is stable and quick. And want all my sd card files to be there when i get the android up and running (pics, music, etc.) I was liking the DL Desire Series ROM by dandiest, is that one good? are there any better suggestions?
Hopefully I can get this all together, i'm probably going to need a very detailed step by step, down to even the minuscule of actions.
Thank you
Thank you
Thank you

It's just you have twocays to flash. Depending of the ROM.
If in the title of your thread ROM it's written "DFT" then:
1/ Flash HSPL (to do this start your phone by pressing the vol- key (keep it pressed until you see a 3 colors screen).
Plug usb and flash from your computer.
2/ redo the same process to flash MAGLDR
3/ boot in MAGLDR (press "end call" will booting your phone).
Choose the option "USB flash" (something like this)
4/ flash your NAND build (on your comp launch as admin "DFT.exe" or something like this
If You want to flash a CWM:
Do the same 1, 2 and 3 steps above.
4/ flash CWM from your comp (same, DFT.exe as admin)
5/ start your phone while pressing "end key".
Choose the option "AD recovery" (if CWM 1.13)
CWM will load.
6/ choose option to flash build from zip
Your done.
NB for step 6 you need to have the zip of your build on your SD card of course.
Best is to put it via a card reader. Avoid using MAGLDR to transfer the zip as a lot say it can corrupt big files.
For detail info read the thread of:
HSPL, MAGLDR, CWM and the one of the build you want to install.

You will most likely need to format the sd card. Most of the people you see complaining about android probably don't do it

I went thru the process not too long ago and it's a daunting one but worth it. Once you get the HardSPL in place, it's pretty easy to reset everything to the orignal state sans the Hardspl (using Task29) should something goes awry.

You can try without, although it may not work. Of course if it doesn't, your phone us not ruined in any way. just save the files you want to keep then format. I know cwm seems daunting at first (i myself was very hesitant to try it) but trust me, once you get the hang of it, it's simple as can be. Also, I've never used g parted. Don't know why that's there, I don't think it had anything to do with cwm.
As far as partitions, you don't need to partition your card unless you're run out of memory for apps. If you have the us t mobile hd2, you don't even need to worry about this.
If you're talking about partitioning your phone, this is super easy and is just party of the process of flashing your dft. Just choose the dev recommended partition size.
keep in mind that there have been very few, if any, instances of people bricking their hd2. Usually, this has to do with flashing the wrong radio. as long as you flash the correct radio, you should be fine.
Good luck!

Purchasing HD2 today and need some newbie pointers

Yes, I did see this sticky with links, but that is by no means a starting point for a total newbie, and by newbie I don't mean someone that's incapable of following instructions, as I've gone through several ROM's on my Pre, G1, myTouch 3G, EPIC 4G, iPhone/3G/3GS. I am just new to WP7 and that sticky doesn't really explain where to start.
Specifically, I am getting a used HD2 with WM6 on it and I want to end up with a dual-bool WM7/Android system on it. I just saw that was possible, but saw different combinations and different methods: WP7 on NAND & Android on SD and viceversa, etc.
Any tips would be appreciated.

First install hspl,than flash a good radio, then magldr,then clockwork mod and then flash a great android rom
Or for win phone stop at magldr and flash win phone ...i know its very short but you will have Tor search for a tutorial for each because there is much to say )).if there is a special question write me a PM

Short yes, but actually, that should give me a starting point, even though it did not explain which OS I should flash on NAND and which on SD or why, which sounds like one of the first things I need to decide. But yes, I guess I will need to do a lot of reading before knowing my path. Thanks.

Hi,
First of all you can't have WM7 and Android at the same time, or else, if you had a TMOUs you will find some tutorials to doi it.
I recommend you to search, you will find aht you are looking for.
At xda-developers.com first page you will find a link to how to do it... ok I give you a tip : http://www.xda-developers.com/android/complete-guide-to-installing-nand-android-on-hd2/
And I think this is not the correct forum to ask this
See you

ok lets clear this up, HSPL, radio, MAGLDR, flash WP7, then follow tutorial to install android as well
Ive not bothered, since i moved to WP7 from android you couldnt pay me to go back, but i think the process is basically, install WP7 with a working small SD card, take SD card and clone it to a bigger SD card and then install android on the SD, there are plenty of tutorials on all this,.
also to be clear, you MUST install WP7 to NAND, it uses the SD card as well, you cant use it just on SD, so if you want android its (or it was the last time i checked) NAND+SD for WP7 and a alternate partition for android.

OK, doest your purchase seems to you as some sort of DEVELOPMENT? I guess not. SO why the hell are you placing your question in development section?
And are you joking about that you dont know where to start? You want dual boot WP7 device. Ok, what about looking for a thread about -fanfare- how to dual boot WP7 and android? And yes, it is present on this forum and I gues it has sticky on it.
YOU ARE LAZY!

Definitely not joking and that thread (which isn't stickied, by the way) is hardly the starting point I'm looking for, since it starts assuming you already have Gingerbread on your HD2 and you know that's now how they come from HTC or your local carrier. See part 1 video for yourself.

if you want to run both wp7 and android it is possible but you will have to flash wp7 nand as uptill now it is the only way to flash wp7 on (nand) and android on your sd card that way you will have both the worlds..

So I have both WP7 and Android booting now (woohoo!), but I still have one problem left, as explained in this thread. Could you guys advise? Thank you.

Here's your problem.
it looks like you didn't have an SD card in your phone when you flashed WP7 or something, you should have like a 3.5gb "unknown" partition if u used a 4gb card the first time. Here's how are/were supposed to do it.
Flash WP7 with a smaller micro SD card than you plan on using (you have to use 2 micro SD cards for this to work, one "big" and one "small") let's use a 4gb for this example and a 16gb.
put your 4gb small microsd in the phone and flash WP7, load up WP7 for the first time and do some set-up.
turn off your phone
put the 4GB card into your computer's SD card reader, and open up that partition manager, you will see a 3.5gb partition. If you have another card reader put in your 16gb and copy the parition from the 4gb to the 16gb, if you don't have a card reader then copy it to your PC or any flash drive with more than 4gb, then take out the 4gb micro sd and put in the 16.
copy the 3.5 partition to your 16gb big card and when it's done, you should see like 11gb unallocated and 3.5 unknown and 200mb ntfs or something.
resize the 200mb as high as you can (11.5gb) or something), then reformat it to fat32.
copy your Android build to the new fat 32 and put the 16gb card back into your phone.
You should now be good to go. WP7 has 3.5gb of space and Android has 11.5 or something. Do not EVER start WP7 without this SD card in there or it will hard reset and you will have no space for WP7

I am finishing the entire process again. This time, I used a different guide for the partitioning. It's very similar, but I think there's one little step in this one that was excluded from the other one and it's critical. Specifically, I'm referring to steps 2, 3 and 7 of Method # 3. Basically, after you've done the partitions in step 4, you must let WP7 reset again. I actually forgot this and experienced the 10GB... 10MB problem again. At that point, I manually reset settings again and was able to get my exact total and available storage right after the phone booted back up. Right now, I'm booting up my Android OS for the first time, but I did boot up WP7 twice successfully, with the right storage amounts.

[Q] Is it possible to convert an SD android os to a rom?

I just had android installed onto my sd card, and I would really like it to boot up into android, opposed to having a dual boot. Is it possible for me to convert my os to a rom? What do I have to do in order to get it to boot directly into android? I'll pay someone to walk me through and do a flash of my hd2 if necessary. Thanks!

Yes, it's possible. Just download magldr version Rom from where you have downloaded your sd Rom and flash magldr,it ll boot your Rom which is on sd. ( note that you ll have to download magldr Rom,xda developers provide same Rom in both type - magldr and sd.)
Goodluck.

still confused^^^^ sorry

Here's the answer in another way:
No you can't convert it to a rom, but a devloper can.
A ROM, at least the way I know, is what you put on your device memory, while what you use on SD is called a build.
so basically to use android on HD2 you have two options, NAND which is a ROM installed on device memory, and SD which is a build copied to your SD card.
The SD method has two ways of working:
1- using haret, which is what you're using now, and this allows you to dual boot easily.
2- MAGLDR which needs to be flashed on your device. It is a tool that runs SD android right from the start, not allowing WinMo to boot. It only needs a file (usually provided by the build's developer) to run correctly, but it's the same SD build.
Note that when flashing Magldr there are certain conditions you should meet. read the whole magldr info page (that's the firsat few posts with info, not the whole thread), because if you spend 15 minutes reading what can go wrong is better than spending hours trying to fix what you messed up.

okay, I understand. How to I run MAGLDR on my phone? Do I just copy it to the sd card? Sorry for the noob like questions ive just never flashed a phone before.

The best thing to do is spend some time reading the guides etc. You are not the only person to ever ask this question so obviously there si already topic that cover this and will have all the info you need.

If you still not getting then pls watch video tutorials on YouTube. There are lots of video tutorials for newbies.

make sure you have a properly formatted, error-free SD card.
Scan in for file system errors, backup your data, then format it using this

make it a full(overwrite) format for first time. and try again.

Whichever ROM you're using is extremely old, so it may have even been a known issue of that ROM (although I highly doubt that) but we need more information as Kamerius said. For the mobile network issue, have you checked that the APN settings are correct?

Well, can you link me to that ROM please? I wasn't aware that there were any ROMs by DFT outside of the Stock Desire one, so I'd like to see it (although it isn't necessary of course).
You're using an extremely old and outdated method of flashing anyway, everything nowadays is flashed via CWM. See this guide and start by using the wipe data thing in MAGLDR, then just skip to flashing CWM with the correct partition sizes etc. It might not necessarily solve your issue, but you might as well do it nonetheless.
Are you trying to insert the SD card after the phone has booted? Just leave it in the phone and turn it on, I don't see any reason it shouldn't work other than if it was a known bug of the ROM or if your SD card is the one with the issues.
I'm confused about your second issue. The OP says that your data connection isn't working (data being mobile network) but the second post says that it's the USB connection to the PC that isn't working? Which one is it? Or are both of them not working?

That's fine, it just means it's an EU/International HD2 rather than a TMOUS. The only difference (spec-wise) is that it has 512Mb ROM rather than 1024Mb

HSPL4 means the package which is used to flash HSPL2.08, it's not a SPL version in itself. The highest SPL/HSPL version is 3.03.

There is no 'best ROM', it's all a matter of opinion. I prefer ICS ROMs such as NexusHD2 and IceCreamTosti because of the HWA capabilities, but you may not like them. It varies between each user. If you decide to flash one of these, you can create an EXT partition on your SD card and use the app Link2SD from the Play store to use that partition.

Did you follow the guide I linked fully? Including step number 2 - partition your storage card for a2sd ROMs? If so, then this is an EXT partition which you have created on your SD card with CWM. If you meant repartitioning the NAND with CWM (i.e. in your case flashing a 150Mb partition) then this is NOT on the SD card and isn't an SD EXT. However, since you have stated that the app App2sd works fine, I think you've done everything correctly. Congrats, you now have a fully functional Android HD2.
The ROM you chose (TyphooN) is a very good one, I used it myself as my standard ROM for the whole of 2011 and a bit of 2012 and it was absolutely great, but right now I personally feel that ICS ROMs are better. ICS is simply the latest version of Android (GB is Android 2.3, ICS is Android 4.0) and it's the best version of Android by far. As well as this, ICS ROMs have full Hardware acceleration. This basically means that games and videos will play a LOT faster on ICS than on GB.
