Hi,
last time i came in here unhappy with my stock HD2 on tmobUK android was just emerging on SD, now i came in here the other day WP7 is available as NAND and so is android....things seem to be a little confusing now, quite a few of these great ROMS are from people whos first language is not english so its quite hard to sometimes understand what they are explaining so i would be greatful if someone could answer somes questions, i have tried to read threads as best i can but some of them, well most actually are well into the hundreds within hours.
1) A lot of chefs describe NAND and SD, i know the difference between the two, but then they get mixed with magldr and NAND with ext4 etc etc..basically i want to flash the phones software to my NAND, i am assuming this is the best way to have it running at its optimum ?..so if i do this why would i need ext4 partions on the SD as well ? whats the benefit of it ?
2) i have also noticed that you can scan a barcode and have a link download a new rom to your phone and flash it, could i do this with ANY rom straight over the top of another without question ? and everything will be as it should be.
3) Does each ROM need to be set up in a different way?, this partly answers the previous question.
4) i flashed WP7 to my NAND (i think)..i was not happy with it and i had magldr installed, i just formatted my SD card to fat32 popped it back in and followed instructions to put [Feb 01][DL DesireZ v3.4][DL Data2SD/Ext4 v2.6][Nand/SD/MAGLAR] on to it.... it took me into magldr and told me to do a few things...did this flash to my NAND ? and did it do what was needed to the SD card regarding format or was it up to me to make certain changes to the SD card myself ?..the phone works and i can make calls, but all the apps that are stated to be in the ROM are not there, i cant find any GPS stuff and when i go to market place itsays its downloading an app but i can never see it.
As you can see i really am quite discombobulated with all this...i would love a easy reading guide that explains everything from A-B and all the terminolgy.
Thanks.
1. Many of these Android roms would swamp the entire memory of the EU HD2, so a workaround is to have partitions on the sd cards to store apps and data, leaving the system to run on NAND. When you update your rom, you just flash the system files and all app and data remains on the sd card.
2. The QR code just allows you to download the rom to your phone. You would still need to flash it AFAIK. (Heven't tried one of those yet). There are basically 2 types of NAND Android roms. One type use the more conventional flash type where you run an exe (daf.exe) from the usb flasher option on magldr. The 2nd (more recent type) packs the roms as zips which you can download and copy to your sd card and then using Clockwork mod, you can flash the rom directly from your sd card. This also allows you to take full backups, try another rom and if you don't like it you merely restore the rom.
3.Each rom and each dev has their own way of building these roms, so you will need to read carefully regarding what to do wrt sd card partitions etc.
4. Flashing WP7 and the Android rom via magldr would have installed the rom to NAND. You would need to partition your sd card yourself prior to flashing the rom. There are tutorials on how to partition the sd card to give you more help.

1) MAGLDR is nothing but kind of a bootloader. You can select how you want to start your ROM. AD SD or NAND or also now you can back up ROMS with MAGLDR... SD ROMS use haret.exe method. NAND uses DFT.exe method. there is another way called Clockwork MOD which uses .zip method.
Differences:-
SD Method: you have winmo 6.5 on NAND and android on SD card.
NAND Method: you install android on NAND itself.
Clockwork MOD: you install android on NAND but the benefits include you can backup your whole ROM in the actual state and flash it back later... So you can try different ROMs without worrying about installing apps and adjusting settings on the ones you like.
ext4 is a type of partition used by system. you can use the ROM which supports APP2SD and put your apps on ext4 partition.
2) As for the barcode ones. I am not sure how that works, but deffinately not as easy as you are thinking...
3) All the NAND roms use DAF.exe method so you do not need to worry about setting up the ROMs or anything. It does it for you. But some NAND roms have capabilities for APP2SD, in that case you might have to format your SD card in some particular way (explained in the threads always) to get ext2/3/4 partition to use app2sd.
4) you can flash WP7 only on NAND as there is no other way to do it for now. As for the new build you used, it has more than 1 versions. SD and NAND. If you followed the instructions for NAND and used DAF.exe to install it, then the ROM is already set up for you on NAND. Now the build you used had data2sd option and you can format your SD card as the author has said to use app2sd functionality.
One more thing, mostly TMO US users do not need app2sd as they have enough space on their phone. So if you are TMO US user, you can opt your self out from that headache.
Hope this helps. Just for the clarification, I am also a newb... I tried my level best to answer your questions...
QR codes are just text, in this case a URL. Instead of making you type the URL on your phone, you can just scan it with a special app, and get taken to the URL. Nothing more.
Thanks guys...the fog is clearing a little now...just a few reiterations..
So if i opt to flash to NAND, is it flashing it to the NAND upon each boot or is it written once and thats it, it seems to take a little while longer to boot these ROMS on NAND than a stock ROM..so for instance, if i was to remove the SD card after shutting down the phone and then start it up again, would it not boot because its looking for the ROM on the SD to put into NAND ?...i understand that running from the SD card it just boots from the SD card.
So basically the last ROM i installed, as i did not pre setup the partitions on SD card, FAT32/1024mb ext4/512mb ext4 and went on to flash the rom it has ONLY flashed the ROM WITHOUT the apps and everything else it was supposed to have pre installed already ?...so i have now setup my SD card and i am going to follow through again from scratch and hopefully have the ROM running with all the said apps.
My SD card being setup FAT32 / 1024 ext4 / 512 ext4 doesnt seem to be a lot of space to store apps on the ext4 partitions, what data goes on what partitions...and do i HAVE to have the ext 4 at the stated sizes ?
Thanks again guys for your input, you have all been really helpful.

If you use NAND then you can start your phone without SD card. The build is on NAND(ROM). Where win6.5 used to be originally. You do not HAVE TO partition your card. You can use whole card at FAT32 and store all your data on there. But if you choose, you can give some storage space as ext2/3/4 partition and store your apps in that partition. The benefit is you can free some space from your phone. When you boot your phone for the first time, it will be in original state. Then you can install apps from the market. These apps will be going to your phone's inbuilt memory by default. But you can use some apps to move apps from your phone storage to ext4 partition. But be aware that after you move your apps to SD card you have to have SD card in all times or those apps will not work when SD card is not there. As far as the size of ext4 partition is in question, 1024 MB is more than enough. As you will have some space on your phone and 1024MB on ext4. I would say if you install more apps than that, then you phone will be laggy like hell. ext4 partition size should not matter according to me.

^ Agreed. Don't do Apps2SD if you don't really need it. It's another possible source of problems (I've had my fair share of system crashes with A2SD on my ol' Magic, and the biggest problem was that there was no way of backing stuff up - stuff probably got more reliable nowadays though), it's not ideal for your SD card and speed isn't optimal either.

People would have you believe otherwise..ext4 is faster but ext2 parsay is more reliable... for the life of me i have followed numerous guides explaining how to format the card, even one i followed from a rom was in perfect enlgish and easy to follow but my phone just locks at the spinning tmobile logo, it wont even boot into magldr...all i can do is reflash a stock rom using RUU...im sure i am doing everything in correct order
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.

What about apps to sd????
Sent from my HTC HD2 using XDA Premium App
Is there a possibility that we can have 2 Android OS simultaneously i.e, MAGLDR version & SD Card version..???
If so, is there a bootloader that let's us select the version as we had in the SD card ROMs..???
You can use this
http://forum.xda-developers.com/showthread.php?t=1090783
to install MAGLDR and Clockwork recovery.
Get a CWM NAND ROM and put the rom.zip on your phone's sd card and flash it via Clockwork.
Then get an sd build, extract it to your sd card, and follow all the installation steps in the thread you downloaded it from.
You boot the sd build from the MAGLDR menu by chooding AD SD, but first you must set your sd directory. To do this, in the MAGLDR menu choose Services, BootSettings, then AD SD Dir, and choose the directory of your sd build.
Once you have flashed MAGLDR and CWM, you must hold down the Power button while booting up your phone to get to the MAGLDR menu.
Make sure you flash the right partition size for the ROM you'll be flashing to NAND

Dear all,
I hope nobody minds reactivating thread.
I'm currently trying to install an Android dual boot setup. I installed a NAND Android (TBD SensationXL v2.5) which works already quite well for me. Now I tried to start an SD Android Build via Magldr. But none except ICS Beta 5 starts. All other start showing their Boot splash but phone boots never the less to NAND Android.
Has anyone an Idea, what the problem could be?
Thanks in advance

Your steps should be as follows
1. Download an SD Android ROM with MAGLDR contents as well
2. Rename folder to whatever you like but the startup.txt MUST have rel_path= same name as folder
3. Place folder on root of SD card
4. Go to Services>AD SD Dir>Desired folder (in MAGLDR)
5. Select 'Boot AD SD' (or whatever the Android SD boot option is)
Oh, and reactivating the thread is infinitely better then starting a new one
Dear Nigeldg,

I'm just wondering why the ICS SD build boots normal while every other tested SD build won't boot

I think the SD ROM is not suitable to Recovery..
I've tried installing SD first, after that i install CWR, n try booting AD SD but got stuck on bootsplash..

I have one question I have android 2.3.5 cynogenmod rom install on my htc hd2
on 16 GB card.... now i also want to taste win 7 on other card.....
Is it possible to use both Os without changing any setting while swaping the cards......
The HD2 (ATM) can't boot Windows 7.
But if you mean WP7, then no.
No because the HD2 can only hold one OS on its NAND, either WP7 or Android.
However, you can dual boot both OS's under two conditions:
1- It must not be a mango version (e.g nodo) .. because Mango locks up the SD and you can't use it for android. (AFAIK)
2- Android must be on the SD (an SD version).

Isn't there a SD card unlock for Mango ?
No its not possible to run both os off two sd cards
I got dual boot on my hd2 mango running as nand and android off the sd card
There is a storage unlock.cab file which partitions your sd card to whatever size you want to run android off the sd card after you flash mango..

a) Got to the back to future WP7 rom thread.
b) Read.
You just install the cab to unlock card and resize partition and then put your android files on the sdcard and boot android via magldr.
yeah but after i did that i cannot boot wp7.I use hyperdroid nand rom and yuki's mango build.Can anyone help i'm new in dual boot and i really dont know what to do but i want to fix it.If there is some way without flashing a stock rom and install the mango all the way from the beggining please share
I have clearly stated that you cannot boot Android (NAND) along with WP7, yet you tried to use HyperDroid NAND + WP7?
You need Android on your sd (refer to the SD development forum) and WP7 on NAND.
Alright so here is the situation. I have HD2 with NexusHD2-JellyBean-4.1.2-CM10 V1.3a installed with NativeSD version. Is it possible to dualboot WP7 without wiping off the Android? Most guides I've seen always mention to install WP7 first, but they are outdated, because they always say to install both WP7 and Android to NAND which I'm not using right obviously. So is there any way to install WP7 with Android existing already?
Note: This isn't really THAT importnant which is why I'm not keen on wiping Android. I just want to experiment.
Hi!
I'm afraid you cannot install WP7 on sd card. Afaik there were experiments with WP on sd but several problem occurred so the best way is installing it on NAND.
If you don't want to lose your data on android you can back it up with Titanium Backup and restore your apps, sms etc. after installing a nativeSD rom. Or you can make a nandroid backup from recovery, try WP7 and if you don't like it just restore your old system.
I used mengfei's tutorial for dual (triple) booting: http://forum.xda-developers.com/showthread.php?t=1896213 :good:
I don't want to install it to SD. I want to install it to NAND along with my Android being NativeSD, but I don't want to wipe Android first but as I understand it installing WP7 into NAND now will most likely break the Android which is why I'm asking if there's way to install it to NAND as a second OS rather than installing it first. Sorry if my English sucks.

Nope, unfortunately there isn't a way to install more than one OS on the NAND (at least as of yet). And Windows Phone requires the memory card to be formatted.
I can list you some options:
- Do what NxStep said and make a nandroid backup, flash WP7, repartition and reinstall the ROM.
- Theoretically, you could make an image of the ext partition on your sd card, and after installing windows phone you restore it. I am not sure of this one, haven't tried or heard someone try it before.
I suggest doing option 1.

Oh well I understand now what you just wanted.
Marvlesz is right, you cannot have both on nand. WP is quite "strict" with installation but you have more options placing the android system as described above. If you install WP right now, it will format your entire phone including nand and the whole sd card as well.
