[Q] [Q in need of A] Will installing NAND Android still allow me to run [SD] Android?

Title says it all

I am wondering that question as well..., how do you access the data/files on ya SD inside Android/NAND Android?

Well there's always file managing apps like Astro, but I'm not sure if it works that way, so, if someone could put kill our question!

Android is Linux based so there should be a similiar command to ls -a where you can see the files and be able to run SD Roms? Or I'm kinda hoping there is..., in SU maybe???

Thanks for the feedback bro, appreciate them.
We just need a response from actual experience; surely trying to run Android off SD wouldn't harm the device in any way.

I don't think we can boot an android build from an android build seeing as how clrcad and haret was build for winmo. >.> but looking at the magdlr notes, if i'm wrong, it has an option to boot android from SD or to boot from NAND, so guess that means you can have an android build in SD and NAND.

NEVER MIND... it failed the second time.

Yes but the build has to be built like a nand build. So you can't just boot the ones you have now.

I just tried..., I done what I would normally do for an SD Build and used the NAND boot menu to try to run the SD Build. Even though there is an option which says you can run from AD SD..., it doesn't happen.
http://forum.xda-developers.com/showpost.php?p=10202441&postcount=146 <-- This makes sense ( no pun intended )

I understand that a Nand build on SD card will work the same as Nand build on phone, that makes perfect sense.
Question is, is the SD card memory used for application files or will it use up all the memory on my phone like Nand on phone does? Is it possible to use a data.img. Of course, the perfect solution would be to add the option in Magldr (Nand) to boot into recovery so the SD card could be partitioned for files and ext3 for extra application system files like we can with a normal Android phone. Then the need to add another Android rom onto the SD card just for extra storage would not be needed for us European users.

[Q] Android and WP7 Dual Boot

With the recent developments of Android and WP7 for the HD2, I really can't decide between the two. Will there be an option of dual boot like with WM6.5? I'd love to have this option.

I would definitely love for this to happen, although WP7 is in the lead for me now, booting android once in a while wont be so bad.

i think itz possible in tmobile usa HD2 with itz 1gb ROM ... two partitions using two NAND OS... dual NAND..

I'm very interested in this option. Hopefully this will be available soon.

I hoppe we find a solution for Leo from EU (512Mo).
Like WIN6.5 + Android on SD ?
My favorite way : Android in NAND, WP7 on SD !!

think we should be able to still boot android off sd with magldr... we just need to switch to a different sd card that wasn't used with wp7. I hope its possible. will be trying it soon.

i would love to do this, i have a 124 leo.

F*ck the 512!
Android+WP7 would be sweeeet for 1024!

im still running an old build of sd, so is it possible to upgrade radio, magldr, win7 nand and keep android on sd?
im not really wanting to give up android just yet, but i do admit i want to see what win7 is like

based by the link above (with google translate), its possible to dual boot with wp7 nand and android sd

Is it possible to back up a android nand rom, so i don't need to download al apps again and set them all up again?

But since your lazy, yes there is. Its called Titanium backup and it saves all your apps and settings into a file. When you install a new build just recover that file from within Titanium backup and all your apps and stuff will be there.

So...does anyone here speak enough Chinese to make more sense of this than Google Translate does? I think some sort of modification needs to be made to init.rc. Possibly system.img too. It's also not clear to me if a NAND or SD ROM is meant to be used. There are some links which I'm trying to make sense of...

Im unsure on how to do this also, if anybody fancys typing it into something we could follow it would be great!
Im in work today and my phone is fully charged ready for win7/android combo

How would you boot android from nand if you can't access the file system of the SD card?
Its an unknown format and magldr surely won't be able to boot anything from it.
Maybe it works the other way round, though?
Or you could use your phone7 without sd card...
hey that may even work.
Limited storage for phone7 - who cares?

That's what I would like to be able to do. WP7 is nice to play with at this stage but I still plan to use Android most of the time.

Half of the sdcard is formatted in FAT32. The other in WP7 system file.

I have already declared in the title dual boot, or have friends do not understand the altar. After the following modifications, select the boot wph start guide wp7, select the boot ad sd sd boot on Android , Android WP7 and dual-boot, the boot options can, without disturbing each other. Start wp7 will not interfere with sd card, wp7 sd card did not even know exist, the question is wp7 little space available, but at least can be used.
Expect experts to address the first time in wp7 can choose to start the occupation of the sd card space, do not fully occupied enough.
-------------------------------------------------- -------------------------------------------------- -------------------------------------------------- ---------------
Thank DFT ! Because SD Android running well, I have not brush Nand Android, waiting for the arrival of WP7.
Today, DFT has released long-awaited HD2 users WP7, I finally started to brush. Brush some of the altar before the access to the Friends of the experience, that really exclusive WP7 SD card, which can later how to run Android.
I have access to the information carefully and found that the SD card as WP7 only system expansion space, the first start of the SD card partition to use. Therefore, I decided to removed the SD card so reserved for Android use.
PC: Windows 7
HD2: SHPL 2.08
SD: Sandisk 8G c4 (from the phone in the show)
The following is the process of Brush:
1. Three-color screen brush Magldr 112 (all normal, NES Set )
2.Magldr start to select the USB Flasher, PC-side DWI (all normal)
3. Phone reboots directly into the WP7, simple to use, after all the normal (free space 98M)
4. Handset off
5. Insert SD card
6. boot holding down the hold button, enter the Magldr menu
7. Set always shows the menu (to decide, because I want to dual-boot often, so set the boot menu)
8. Set the boot path SD card Android
9. Guide the SD Android, the show finished HTC interface (kernel, Init after) boot into Andoird animation between the phone restart
Episode: I stupid out, SD card, there are a lot of information not backed up, hands and no card reader, can not enter the Andoird, the backup can not, WP7, when not installed into the SD card, do not expect him to. Fortunately, there are menu items that Magldr USB storage (my first use of Magldr), select this option, the memory card sorting.Remove the SD card all the Android-generated directory (the directory is generated Android, do not also delete a Android), re-boot, the first screen to enter Andoird die.
10. Online access to information, Magldr guide SD card Android, need to modify inti.rc.
11. Will system.img (I use the DHD Android) copied to the Linux modified.
In the service ril-daemon / system / bin / rild-l / system / lib / libhtc_ril_wrapper.so append --d / dev/smd0 nand parameters, to support
Nand boot.
12. Returns Android phone, after a successful boot.
Nagging: WP7 egg really hurt, WIFI without any settings, I have been using a static IP, can not be set.

He's dual booting, but none of the SD card space is for WP7. It only has around 100megs left. WP7 automatically RAID0's the whole card with internal memory for space. That's why removing the card screws up WP7 and a hard reset has to be done. I think what would be ideal is if the card could be split into 8gb for WP7 and 8GB for Android, but part of the problem is you can't call HARET.exe or CLRCAD.exe because there is no OS to understand those executables.

things have moved on a lot..a little help please

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

[Q] How to install dual boot alongside my present SDrom

Hi,
I have MAGLDR installed.
I am happy with my present SDrom (in fact the best and fastest rom I have tried regardless of Nand or SD type).
How do I correctly install NAND rom alongside my present SD rom?
I do not want to destroy my SD rom.
btw, I tried to install and everything seems to be fine, but I think that NAND rom once I boot in to the Android is asking for SD card permissions...........I THINK!
How do I install NAND now correctly?
Regards

You should be fine to install normally as long as you don't delete the contents of your SD card. Just follow this guide but skip the step which asks to partition the SD card. It doesn't matter if the ROM needs to use the SD, as long as it doesn't format it (and I think it will warn you about that should it happen).

[Q] Loading SD ROM via MAGDLR---Stuck at Logo Splash

Hello,
I installed a NAND Android (NexusHD2-ICS-4.0.4-CM9-HWA V2.6 (Kernel: tytung_HWA_r3.4) which I’m quite happy with but would like to try out some SD card ROMs.
Now I tried to start SD Android Builds (e.g.JaguarMIUI-V21 to run via MAGDLR v1.13 and MccM MixTheme V1.3 HTC) but no matter what I do it’s stuck at the Boot splash. I even notice that the data.img gets built. But no Android gets loaded. Just logo splash. I reformatted my SD card. Same result.
What are the considerations: Does only the Kernel of the SD Card ROM matter? If so which one is recommended? Does the resident NAND ROM matter? The version of MAGDLR? SD card format/partitioning?
I’ve seen others encounter this but it’s been hard finding a definitive conclusion. Most point to using the right Kernel for the SD ROM.
I have followed the instructions to copy rootfs + startup.txt to ROM folder as well as to ensure that the startup.txt shows the appropriate path (i.e. rel_path=Android).
Any advise would be appreciated.

Hi, just take the sd build as it is. Everything will be ready to go, kernal etc. Nand will not make any difference as you are rebooting from the card files.
Check the location of your files, you can rename main folder but change rel_path in the startup.txt
Otherwise, also in startup.txt, check the data_size, 512mb file could take 10mins or more to create

Thanks gazzacbr. Note I didn't have this issue when I was on WM 6.5 and loaded SD ROMs via HaRET.exe. Now I'm on NAND Android and attempting to build and load same ROM from MAGDLR using Dev's instruction. I notice some report similar issue in individual ROM threads but I've not come across consistent root cause and resolution documented. Perhaps I'll try a newer SD ROM and see if experience is different from the previous SD ROMs I've attempted.

I am able to now get yugoports miuiv4.1 to boot via MAGDLR. Still not sure why I couldn't get the other MIUI SD ROMs to load. I have some old data.img files from those roms from my wm6.5 days. I'll extract data that I need by leveraging ext2explore app. gazzacbr, I saw you mention this app on an unrelated thread and so I thank you.
