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.

[Request] SD - CM7 ROM bootable from MAGLDR

so I have not seen one ROM on the entire forums (in any flavor) that is an SD card ROM and can be booted and work from magldr.
But why would I need that when we have NAND? a few reasons:
1) If you have a NAND ROM you really like but want Sense for a day, or AOSP. etc.. it's kind of a pain to do a backup, wipe, flash, then restore later, be much easier to just boot one from MAGLDR.
2) the real reason I want this. If you have WP7 flashed on your phone, you could still use Android (since WP7 is pretty cool, but it's nowhere near Android) by turning off your phone, taking out your WP7 sd card and switching it with another one with the Android ROM on it, boot into MAGLDR, launch AD SD and you're good to go, when you're ready for WP7 just switch back to the original WP7 raided card and boot WPH.
I can't get any of the haret roms to load right or work when doing AD SD, the only thing we can use that for right now is CWM, which is cool, but really I can't be the only person who wants this. And CM7 just happens to be my favorite version of Android atm. Of course as resources allow donations would be forthcoming (even though we know you guys don't do this for money, it's nice to show appreciation).
Just want something nice and stable (or somewhat). The MDJ CM7 ROM i was running from SD had like no issues. Hell I'd take a CM 6.1 or even Sense or anything really at this point.

+1.... We need more sd bootable roms in general. There has been no work on sd androids since nand came out. I, too, want to use wp7 on nand with android from sd.

I support the idea of more SD ROMs bootable via MAGLDR too - ideally I want to tri-boot with WP7 for fun and fiddling, a DHD ROM for normal use and a AOSP ROM for development.

Android on SD Card + Original ROM

Hi there
So I'm reading for a while the topics about android on SD Card, but I couldn't fix some issues and I hope you'll get me out:
1) Can I use the original ROM from my HD2 and install Android on a SD Card
2) Is there a possibility to install Android on the SD Card and get a boot loader where I can choose between a WinMo boot and an Android boot or do I have to boot always WinMo 6.5 before booting Android?
3) I read that the speed with the SD Card Mode is slower than the other ways, how can I understand that? Do I have to wait longer during the boot of android or are there also speed problems while working with android?
4) Also on the speed problem: Which SD Card would you recommend for Android on SD? Are there any measurable speed differences between the CD Classes?
best regards

Yes you can install android on SD and use WM6.5. Its what most of us did back when you couldn't NAND boot android. There are several bootloaders around yes, however you always have to boot into windows in order to boot SD android. This means android SD boot time is much much longer than NAND, however this is not really that big of a problem. As with the speed problems with the ROM itself, well lets just say i much rather prefer NAND to SD, I used SD for a long time and NAND was something that made me very happy. I didnt really see a problem with SD builds however I simply felt more secure using NAND. Also, with an SD build the speed of the phone is dependent on your SD card class, most SD cards are class 2, mine is class 6 and my SD build worked fine however I have seen people saying its slower with a lower class card. I don't know whether its actually a real issue, like you need a class 4 card to run android properly however people sometimes complain. This however could simply be their ROM's/Phones being slow.

Does this version (FEB 14)[SD]MCCM HD V4.0 [DESIRE HD Sense] Perfect [kernel gauner1986's] work at anyobody with the original ROM ( 3.14.207.1 ) and 2.15.50.14 Radio ?
My actual version is the
[Dec 18][RAM] darkstone SuperRAM FroYo v1.5 [kernel: Hastarin custom]
and it works.
The installation of the MCCM is exactly the same but it doesn't work.
When my device reboots there is the HTC logo on a white background and i have waited for an hour but nothing happend.

Sounds good. So what I don't understand: Booting Android from SD Card - does WinMo Shutdown or does it still run in the background? So is the full capacity of the CPU & RAM available or not?
I think a Class 6 16GB should be enough for that game. I actually like my original ROM and would like to try android just for fun, so I think the NAND Method wouldn’t be that, what I’m looking for.
Do I have to buy a card reader for my SD Card?
Any other experiences with Android on a SD Card?

My opinion about Android on a SD card is very positive.
My version is very stable.
Until now I hadn't problems with any bugs.
The browser is very fast, the camera good, the connection to WiFi is perfect and all games work
But it's clear that you have to charge your mobile often

SD android also has a high battery drain, I dont know the exact figures but i think in standby sd builds are 5-10mA, where most NAND builds are 2-5. You wouldn't NEED to get a card reader, however it would be an extreme help. SD android is very good, however NAND is better for me because personally, android blows the socks off WM6.5, so I just decided to go all out. SD android runs on top of WM6.5 yes, however WM6.5 is shut down so you do get the full power of ram/cpu etc.

I love SD, partly because I love my build (Black&Blue Remix), and have been rock-solid on it since November. I keep trying other SD Builds, as well as NAND builds, but I'm so hapyp with my set-up I have no desire to change, at least until builds with updated Sense/GingerBread/Honeycomb come out
I've got the Extended Battery pack so maybe that sways my judgement.
But I have no qualms in recommending SD!

To make this part clear: I can only download a Android ROM, put it on my SD Card, insert it in my HD2 and here we go? HSPL is only needed when I'm trying to flash android?

So the question to you is:
What do you understand under high battery drain? I recharge my phone every night, not depending if it's empty or not (does this have an influence on battery life btw?), so... does the battery last for 2-3 hours of surfing, emails ... on sd android ?

A Few Questions about Windows 7

I have been using a NAND Android ROM since they came out and love it, but I'm curious about Windows 7. My questions are as follows:
Does Windows 7 run off the SD card or NAND?
Can I go back to Android if I don't like it?
Does everything work on 7?
Is there a working Pandora hack?
Thanks for anyone's help on this.

1) It runs from NAND
2) Yes, simply flash your preferred NAND via MAGLDR
3) Yes, if you get your activation code to use Live services
4) The jailbreak is called "Chevron" and is cooked into most custom ROMs - but not the very first "Leo70".

The nice thing about the HD2 is you can install wp7 on your NAND, and still boot android off your SD... I went from NAND android back to SD android builds so I could also use wp7, and I've noticed almost no difference in performance and battery life between NAND android and SD android. Only thing you miss out in with SD android is that there's no clockwork recovery... but it's easy enough to boot different builds and make backups with SD android.
WP7 is great, but it's still missing some functionality and apps that android has, so having both is perfect. At this point, I would have a very hard time choosing between the 2 OS's if I had to get a different phone. WP7 grows on you very quickly. Can't wait for MS to put out the update that gives multitasking to WP7.

[Q] Can i have WM 6.5 and boot android from SD as dual-boot?

I've been playing around a bit with my HD2, installed ubuntu v0.3 and android (both using haret. the problem is that booting android using haret is really slow... the logical solution would be to put it on my nand. if i would do this, would i lose WM? I really want to keep WM cause you need to boot ubuntu via haret.
Does anyone know a trick/solution?? all help appreciated. Thanx

Hi,
Sorry to say ,you cannot have all three.
Either WM + SD android boot(as you say ,slow),or Android on NAND (fast).
If you choose to go the way of the NAND...I suggest lots of reading,starting with the guide in my sig number 2.
Good luck .

If you put Android on your NAND, yes, you would lose WM.
You can keep your WM and boot into Ubuntu/Android via Haret.
There are some apps/tools that helps you automate the dual-booting.

Like the two other posters before me said, if you want Windows Mobile, then you will need to keep your SD build. Once you go NAND, you will lose Windows Mobile. My experiences as well with SD builds is that they are much slower to load than NAND. Anywhere from an additional 1.5-3 minutes longer than NAND. The fastest loading NAND builds are the Gingerbread ones. They load for me in under 30 seconds. Non-Gingerbread NAND builds seems to load from 1.5-2 minutes. Search the forum for the dual boot up options to speed loading a bit quicker while helping to reduce battery drain. I am currently using a NAND build but when I was using an SD build, I made sure to have my dual boot up setting at 3 seconds to ensure a better battery life while quickening the boot up time.

Try taking a look at these dual-boot apps/tools:
Exceller Multiple Build Loader for Android/Ubuntu
Jmz Android Dual-Boot for HD2
Android/Ubuntu Loader for HD2
