[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.

Death of SD/RAM Builds?

Hey everyone, I am glad NAND is finally released (for those that have been waiting for it), but I'm wondering if theres anyone (yes I know the pros of having NAND Android) that prefers being able to dual boot? I'm starting to feel that work will halt on the SD/RAM builds. Any reassurance? Thanks guys.

I'd like to keep SD builds as well.

Naw I think a lot of us non-TMOUS HD2 owners will still use SD builds. Reason being, we just don't have a lot of storage space, which many of us need. Unless Devs perform the ext4 partition thingie onto or sd card, for us to expand storage, storage will still be small for non-TMOUS HD2 NAND users i guess.

Yes, RAM builds are the biggest source of competition for NAND - however, I haven't filled up my storage yet with my apps and still have about 90/100MB left of phone storage.
What about installing apps to SD card???
Signal strength is much better on NAND though for me.

Can you report how many %of the.time without signal with sd and %with nand? I believe you but I didnt test nand roughly because of the memory limitation. But I guess thats gone now

I hope the response will be "No". I use the PSX Emulator (FPSece) on WinMo so I prefer switch on Andoid or on WinMo.

Nand is obviously the next stage of evolution in rom development towards running Android natively on our hd2's.
sd card builds have the great advantage of being swapped easily, especially with multiple sd cards (I have two, one stable daily use which is fully configured and one experimental)
Moreover the risk of bricking your previous device is rather low from sd..
I am not very clear about the difficulty of transferring a build from an sd build to nand and vice versa, but if there could be a migration tutorial, as a sticky we could have both, latest builds in nand and the choice of running them from sd..
Is this technically possible? Which factors could inhibit easy migration?

I thought originally MAGLDR was supposed to be able to multiboot Android and WinMo (probably a non-sense version of each due to space)?

I hope MADLR can do the following soon:
- Load SD\RAM\NAND Android from custom folders on the fly
- Allow backup\restore of the data store
- Load WMP 6.5 and maybe even 7
I think this will keep the flexibility of multiple build loads alive which will benefit the user and the devs. I know some of this should be coming but it would be nice to get all of our belated Christmas wishes.

not sure but,,
im not sure but the aMAGLDR menu does also have the option to boot from SD-card, i havent tried it yet though..
also one thing i still want is the ability to boot my ubuntu-sd-card build, now i cant use haret.exe im not sure how to go about the dual booting thing ??
much stuff to try out
***edit***
ok, just put the contents of an old sd card build directly onto the root of an sd card (ie, without the 'android' folder) booted phone holing power key until magldr menu shows, then select boot AD from SD and it boots just like the old sd card with haret method, -
so far i see it finds zimage and initrd.gz, then i get the boot screen, .... looks like dual booting is still an option even if it may need a bit of tweaking.. i guess its just the startup.txt that needs to be read for it to boot properly ,
*********

I think in the original NAND release thread, Cotulla explains that a SD build (haret.exe) and a NAND build are very different, to use the SD boot option in MAGLDR, you need to put the content of a NAND build on the SD card, somehow...
edit: forum.xda-developers.com/showthread.php?p=10202441#post10202441

I would like it if they could implement a better DFT installer, which had options such as
• Install to NAND
• Install to SD
• Customise partitions
• Multiboot
Instead of just being able to install to NAND. This way, we can have a single installer / release for both methods (and this would make it easier for chefs )

I think it's impossible to say for how long - but on Darkstone 1.5 RAM, and MDJ's HD4.6 I would find the signal to have disappeared at least once a day up to three times - requiring a reboot of the phone - airplane mode did not seem to work.
After reboot signal would return to full strength in the same exact spot.
Problem is the signal would be lost in a pocket or on my desk and you simply would not notice it until you went to use the device - in fact the first time I realised it was happening was because I was getting far fewer emails/smses and calls and the phone was utterly quiet - very peculiar for the holiday season and party planning.

I haven't as yet downloaded a NAND build although i may well do that this evening, however having downloading many different builds for Android over the last few months i can safely say Dark Stone's SUPERAM blows everything out of the water in terms of speed it really is very fast which IMO is very important.

Windows Phone 7 from SD card or Android/ WP7 Hybrid ROM?

I was wondering if it would be possible to either Boot Windows Phone 7 through MAGLDR from the SD Card like you can Android by maybe partitioning the SD Card so it cn have it's own space?
Or a more realistic option which would be to have a NAND ROM that includes both Android and WP7 installed to the NAND and partition the SD card for storage? This second option I believe could be possible if the NAND is partitioned correctly to allow them both to run and then you could select them in the MAGLDR!
I would like some dev feedback on this as I would try building a ROM myself but I don't know the workings of the partitioning system in MAGLDR well enough to try!
Thanks in Advance for any help!

I've seen that but what I want is to boot Android and WP7 from NAND NOT run android from the SD Card like that guy done because that makes android run slow and I want android as my primary OS!

I run Android from SD as my primairy OS, WP7 is on NAND just to play with and test it. I tried Android on NAND, but to me it wasn't noticably faster then when running from SD.

Snap I'm using sd build of Android from magldr and it runs fine even boots ok, there might be a little lag when doing something the first time but other than that its great

Well the thing is I like to use a fully fledged Desire HD ROM and it's stupidly slow from the SD card... my current build is squashfs'd so only takes up about 200mb for the actual OS and I'm sure WP7 could be fitted in the rest of the space and like I'm doing now I can use EXT4 on the sd for data! Now what's needed is if someone can build a hybrid ROM!

Hi, anyone can share how to u do this ? is it through the method that uses 2 sd cards during the formatting stage ?
Btw, what if i dont mind swapping sd cards for diff os ? Can this be done and how ? I tried to insert another sd card which I previously use for my android sd build, tried the sd boot , it gave an error of sd kernel . anyone can advise ?
Thanks !!

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] HELP!! I was going good until these came along!!!

Ladies & gentlemen;
Good day!
Well, I am one of those who admire the XDA BIG TIIIMMEE!! However I have an HD2 and managed to have it as a NAND Android after the help of the XDA (as usual of course!) Anyway when I started looking for new ROMs I have noticed that there is new method or way which I do not grasp, comprehend and assimilate AT ALL....ZIP that is, such as [A2SD+], NAND SD and ClockworkMod.Recovery!!!
What is the difference between running Android on NAND & SD with ClockworkMod?!
I am sorry people because truly I must have missed threads or the way of understanding, so hopefully you'll going to be the teacher of mine for now and always!
Could anyone help me as if I am 7 years old?!!!
THANK YOU XDA & Members!!!!

Android nand is running off internal memory. Sd option is what it says, a build running off your sd card opposed to running it with nand.

Thank you for your explanation, but does that mean if the Android runs off internal memory would make the running proccess faster or it would hepl smoothen applications response?! What is the use if I already have the internal memory, wouldn't be even better off?!

Hello
SD Builds start to boot from SD card while being on WM6.5. The hardware shutsdown WinMo and runs Android on it.
NAND Builds run from the internal memory of the phone(just like where WinMo was before)
RAM Builds load all the OS from the SD Card inside the RAM.
[A2SD+] means that you can use a small ext2,ext3 or ext4 partition in your SD Card for increasing your internal storage memory for installing more apps... so this means more internal space.
ClockworkMod is a small linux-based booting utility allowing users to install Android Builds on-the-go which are stored as zip packages on the SD Card. It allows you to install new kernels as update.zip packages as well without having to re-format your entire phone again, or just to erase all personal data on the sd-ext partition.
So, in fact a lot of things have changed in the last 3 months... these are just a few features i can tell you about every method, but at least I hope this will help you to understand quickly a bit about all that.

You know!!?? I Thank you all guys!!!!

NAND runs off the internal memory and even though you get much lower Quadrant scores, NAND is much more responsive and smooth.
The only reason SD based builds get more Quadrant is because of I/O speeds thanks to the SD card.
SD builds are fast, but NAND builds are much SMOOTHER and reliable and if you can do something on SD, you can do it just as well on NAND (gaming for example).
