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
I am about to install Android on my HTC HD2, and the advise I was given was that I must use the SD method. I just want to be sure.
I need a system where when I start the Phone Winmo starts up, and then I run another program to run Android, and then I can go back and forth (via reboot or some other way).
Thanks for your advise and information!

So far as I know, you'll have to go with the SD variant if you want to keep WinMo. That way, WinMo is only a re-boot away. It's the method I prefer as I'm not so taken with either Android or WinPhone to go for the full NAND flash.
yeah, you would need to use the SD card method, i would recomend using RAM builds because they are very fast!
Yes, you must avoid the NAND versions, cause these will erase your Windows Mobile ROM and replace it by a Android ROM.
Thus, you have to choose a build inside the "HD2 Android SD Development" thread.
But here inside it is not always simple. Cause for some SD builds you will need to flash MAGLDR to be able to boot these builds, while for others the old method of executing CLRCAD and HARET is much simpler.
Hi!
I forgot to format my SD card when I installed android, so I was thinking doing it now (just in case, it might get a little better). Do I connect the phone and do the formating through ''My PC'' ? (I don't have a SD Reader or adapter) Or i will have a problem with that?
I've installed Frankstine, and its very good, but I want to test a few so I choose wich one I keep is there any other cool rom? (I'm looking for some rom with Sense )
Thanks!
you can simply format it from android or CWM. if you format it from windows however make sure you keep FAT32 file system, android doesn't recognize ntfs
Some ROMS write files to the sd card for use with the ROM,so formatting it may cause the ROM to stop working properly.
You should really format your sd card BEFORE you install a new ROM.
After you format it you want to make sure you have the correct partition for the ROM you want to install.
ALWAYS BACK UP YOUR SD CARD BEFORE YOU DO ANYTHING TO IT.
P.S. check my sig for a good sense ROM
Yeah keep backup of everything that you want in a folder on your PC. Do you know what program you need to create an Ext partition with? If you do well then its easy.
But I suggest you buy a card reader - they're not too pricey and they will always come in handy. The easiest way to do it is through MAGLDR (supposedly buggy but I've never had any problems personally) or CWM. I've found that using CWM I would regularly get 'Bad Disk' on Minitool after using it though. Don't do it when you're booted up in a ROM as it might mess up the ROM, and some ROM's that use Data2SD make sure you don't mount your SD card while using it as it will most likely cause your phone to reboot and it won't mount, so its useless basically.
Btw, good to see you getting Android working or your HD2 haha.

Hi,
I intended to post this question to the [3.Nov.2012][ROM] NexusHD2-JellyBean-4.1.2-CM10 V1.2 [NativeSD] thread, but not allowed to (http://forum.xda-developers.com/showpost.php?p=32624318)
Can someone help me redirect the question? Thanks!
First thanks for the great ROM, tytung. It looks great and easy to install.
I have a HD2 and wanted to dual boot WP7 and Android. Found this new method NativeSD and decided to try it. But once I installed the ROM (through MAGLDR 1.13 and Recovery 4Ext 2.2.7), everything works fine, except that the camera app (and other apps) says that it cannot find the external SD card to save the pictures. It does not give me options to save on phone. But since both system and data are on external SD, and that partition is treated as /mnt/sdcard0, I am not sure if I am supposed to have an external SD card from the perspective of Android.
Cannot seem to find similar post with this issue, so I must be doing something wrong with partitioning. Could you help??? Thanks so much! I am inches away from having a great Android JellyBean experience on my HD2.
Thanks!!!
-----------------------------------
Details:
4 partitions on my 16GB SD card:
1) FAT32, 3GB (this is the boot partition, where I installed Recovery 4Ext and through it, installed the boot files in /NativeSD)
2) Ext4, 8GB (this is the system/data partition, where installation put all Android files)
3) Ext4, 2GB (this is current empty, reserved for another ROM that requires two partitions)
4) Other, 2GB (this is a WP7 partition)
I formatted these using Mini Partition Tool on Windows (not via Recovery 4Ext)
I think you need to run CHKDSK on your FAT32 partition of the card with fix option, once, using a card reader and computer. Once done, put the card back to your phone and boot to your preferred Native SD rom. Then check whether you applications are able to trace the SD card. Should work, since the same worked for me, when I had a similar issue. Hope that helps.

Hi dheerajk27, thanks for your quick reply. Was wondering
1) should Android JB think that I have an external SD?
2) where will this external SD be mapped to? The Fat32 partition? The same Ext4 partition as system & data?
3) what would chkdsk do? I just want to make sure that it doesn't mess up the Win 7 stuff as well.
Thanks!
Hi braveliquid, welcome to the forum.
Did you set all your partitions as primary using minitool?
1. yes
2. depends photos/music => fat part, apps=>ext part
3. not sure either

Thanks for your reply. Upon multiple trial and error, I found out that the logical partition is the culprit. When I have 3 primary (FAT32, Ext4, Ext4), Android can recognize the ext SD card. However, when I have 3 primary and 1 logical (the Win Phone 7 partition is made logical by windows), then Android does not recognize the ext SD card anymore.
Any thought on how I can resolve this? Or else I will have to keep 2 SD cards, one for WP7, and one for Android. Doable, but a bit of a hassle.
Thanks!
use minitool and set your wp7 partition as primary too.
Problem solved.
you could use two cards, i am at the moment (I keep spare card in a cellotape pocket on inside of battery cover). You can also dual boot without partitioning see http://forum.xda-developers.com/showpost.php?p=34009754&postcount=1126 but only really as a backup phone in case wp7 goes wrong and you are away from pc.

Thanks Robbie. Yes, I have set the WP7 partition as primary and then it works! I am liking the Android experience (have been using iPhone).
Btw, in WP7, it is asking me to update software (I have a very old WP7 installation, migrated to dual boot in early 2011 i think). Can I just upgrade WP7 like normal (i.e. by connecting to Zune)? Or will that destroy MAGLDR? If that won't work, how can I upgrade WP7 to 7.5 or later 7.8? I cannot use Windows Market Place apparently with the old WP7 OS.
Thanks again!

I would just flash one of the new wp7.8 roms, your choice which. Ansar's does not seem to be able to use the new wpbackup app at the moment.
With Hd2o and pdaimatejam you can backup your phone and restore apps sms calls etc. Sooo much better for trying out new roms.

Hi
I just wanted to know what operating system beside windows mobile 6.5 I can install on a HD2 without an SD-card?
I know it's the best to get an SD-card for installing something else than WM6.5, but I get the HD2 tomorrow and the SD-card arrives to the retailer on Monday, so I can't wait to get going. I mostly wanted to install Android 4.x.x on it, but from what I read, it's almost impossible to install Android on it without an SD-card.
Welp, you can't install Android on SD, that's for sure, and installing WP7 without it is not a good idea since the OS takes majority of internal memory and you are left few megabytes. You can also install some old Android ROMs which are distributed not through zips, but through special exe files which are compatible with magldr. The rest (which is all the newer ROMs) needs to be installed through recovery which needs SD card to install it.

well i don't know much but if i'm not wrong you can install android on your phone without an sd card by using the nand method. you can read more about it here: http://forum.xda-developers.com/showthread.php?t=893948
