So, i have a htc hd2 running on android and i love it.
However, when lock my phone using the end call button or something.
I would look back at it after a while and the screen will stay black.
I try pressing the keys and nothing happens.
When i call the phone, it rings but i can't use the touch screen or see it.
It happens quite frequently. The android i have is darkstone froyo.
So it works but pretty frequently, the screen would go off and stay black.
What do i do?
Unfortunately threads like this are completely pointless unless you were to elaborate on which version of HD2 you have, which RADIO you have, which build you have, the current zImage, which Windows ROM you have.....

I wanted to see if Android would work on my HD2 before flashing a rom and changing my phone but I have this same problem as well.
I boot up Android and eventually I put the phone to sleep with the end call button and I can see the screen goes black but I can tell the backlight is still on. Then I try to unlock my phone and it never wakes up no matter which buttons I press. I eventually have to take out the battery to reset the phone back to windows mobile
Then again... I am also just running the U.S. T-mobile version with stock windows mobile 6.5 out of the box with no flashed rom with radio version 2.10.50.26
I will be looking over the sticky thread and doing the full conversion today but if anyone knows why it does this I would like to know so it doesnt happen even after I do it the correct way.
ooops. accidently replied by accident.
Same problem here.. I'm using chuckydroidrom, shubcraft 1.5 , radio 2.10.50.26 , have tried almost all the builds, radio versions, but result the same... would really like to know if anyone else has the same problem.

Same problem here. I tried on two hd2 phones. Everything is works fine but i cant end a call because the phone freezing. I'm using 2.15.50.14 radio and magldr113.
I gave up on the sd androids and went with a nand build, much more stable much better battery! Research builds READ THE POST and find one folks have the least trouble with.
I am currently using Motoman234's Moto-Mytouch4G V3.3 based on Iced Glacier by teamsilence. Shear brilliance in my opinion! i have tmous as well this nand for me is flawless. Everything works great and my battery will easily last the day. I had been using Darkstone SuperRAM FroYo v1.5 but the battery drain was murder. Great build beautiful and feature packed but not usable for me due to enormous battery drain. Ya installing them takes more (install hspl then magldr, then clockwork mod THEN the nand) but well worth the effort plus once all that is done you can change builds easily.
so far the core Droid series is great the v1.4 is fast and stable!! i can get up to 2500 on quadrant scores love it so much

Actually, if you know what you're doing and make sure there's not anything unnecessarily draining your battery, SD builds and NAND builds have pretty much the same battery life. You may be able to get slightly better battery with nand, but not a noticeable amount. I get 3-6ma battery drain on standby with most SD builds I've used. Performance isn't much different with SD builds, either. Main pros of using NAND is you can use clockwork recovery and can change SD cards while using android. If you're not going to use winmo or wp7, you might as well use NAND android, but if you still use winmo or wp7, it's probably not worth losing those for the small bonuses you get with NAND.
I used NAND android for a month when it was first released, but I'm back to SD builds because I have WP7 on my NAND... and I can notice no difference in the performance and battery life.
I am using a SD build and have no problems with it. As long as you're smart with it you will be fine.
To answer the op's question, I would upgrade your radio first. It's too low of a version.
Second, what rom are you using?

While I agree SD is better if you want to keep windows I disagree strongly on the battery life, at least on the SD builds I used. I would shut down bg data, wifi, bluetooth, location, and data when it was not in use but still had horrible battery drain (50 to 60 ma sleeping) and could never make a full day with out a charge. Now wifi and bg data stays on always I seldom NEED a recharge most days I can get nearly 2 days out of my battery. I tried different "battery savers" to no avail, applied every patch the developers suggested and researched extensively.
IMO "Know what you're doing" is a rather obnoxious statement.
In my experience, it seems to depend on the build. It may seem trite, but there are tradeoffs in all the available builds and different people do fine on those that suck juice, because certain features they want are there. I like the SD versions because sometimes I need WinMo, and it's easy to move between them.
As you guys all know Darkstone made a build that runs off the phones ram which i find is a fast build but Cotulla has released his nand desire build. So..which one is faster? any advantages/disadvantages between the two?
For me (when i do not look at quadrant score) the NAND is much smoother.
Ok the quadrant score is lower,but that is because of i/o writes.
But graphical is is faster,i love it
Try it yourself first?? So you have your own feedback ready to share..
By the way I'm gonna try now both of them for few days each.. let you know then.
Happy new year dude
Sent from my HTC HD2 using XDA App
I actually already tried them both. Nand needs a little more playing around with but it seems smoother. Or maybe its all in our head that nand is smoother since we have been waiting for it so long
I have the ram version its very fast it satisfies me but I wanna know about the ROM release, please share ur Xperience
Both Dark Stone and Cotulla and his team deserve to be commended for their efforts,nice one folks
I have yet to try the NAND ROM but i have Dark Stones Froyo SUPERAM Build on my phone and have had little or no trouble at all and the most important thing is - it is blazing fast,much much faster than any other build ive tried so i would be inclined to stick with the build that is faster,ill keep an eye on Cotullas thread and may try it but for me the speedness of SUPERAM is the winner but everyones different.
I thought most of the task killer are trying to release RAM . and says it saves battery also. now you are going load your going to the RAM. any expert can explain this ?

Well, from what I've seen so far smoothness-wise NAND Desire stock is good.
However, market downloading speed for me with Darkstone's build is over 1mb/sec, with Cotulla's build it's more like 250kb/sec. That's still reasonable but not amazing.
Additionally, whilst reinstalling my programs which I've backed up with ASTRO, it's quite clear to me that darkstone's RAM build was faster in installing applications.
ON THE OTHER HAND,
the NAND build wakes up instantly, as in INSTANTLY, when you press a button, even when it's sluggish due to being in the middle of loads of work.
So far, this is all I've noticed though I'm sure I will notice more as time goes on.
Does NAND flash do anything for battery life?

My main focus is power consumption, my HD2 can't handle more than 6 hours of heavy use. I receive/make calls a lot, and I constantly use the messaging system... I have to be plugged in all the time, that sucks. Is NAND better battery wise?

U can't modify ram builds extensively cause they are read only. U can mod NAND. In performance its seems to be on different. Except slower booting
Don't think we will know about battery for a week. We will see
Sent from my HTC HD2 using XDA App
as stated, only really thing i liked about ram was the quick boot but being the hardcore user i am i was constantly getting the device full error and needing to reboot due to max ram usage. Nand all the way
I really love the NAND and the Ram versions (thanks devs)
They are both smooth and working fast, but the problem I have is the amount of space for the apps.
The RAM version would let me install all my apps into the SD card as the DATA file is found in the SD card. Yet with NAND I can only install a handful of apps which in my opinion is the biggest disadvantage other than that I’m happy with the NAND version and still testing
to these who are running nand or ram builds
The main Question is the batterylife. Can anyone say somethig about this? How is it on RAM and how on NAND builds? That is the 1st fakt i want to look at.
And how about the Market download speed? On SD builds it's very slow, any changes?
At RAM builds there are still things like GPS not working, so they are nothing for me, at NAND builds i don't read anything that doesn't work.
I have two HD2's
First HD2, DarkStone SuperRAM 1.5 with patches from that thread, 5mA with correct configuration. Lot's of free RAM. After 10 hours usage with auto sync on, mobile data off lost about 10% of battery.
Second HD2, LEO "Stock" NAND Android, bunch of HTC apps/services running in the background, started with 3 to 5mA in standby right now. It fluctuated to 60mA, but came back to 4mA now, will have to check how it does over normal usage for couple of days.
NAND UI is faster than RAM.
Bottom line, based on your configuration mA in standby will vary, I feel HTC is too much of bloatware and designed for non-geek demographic.
Update: Unless you really love all HTC Sense, HTC background apps, widgets and services, I would suggest not to install stock NAND ROM.
i tried already 2 nand roms...all i can say that nand rom is fast indeed..!tried stock desire and desire HD nands rom for hd2..
So...nand is very stable and responsive..no lags at all!all works great..!the only bad thing is that your phone memory is low!!with desire stock phone memory is 80mb and desire hd nand is 156 mb..!compared to ram version u can extend your data.img so u can have more phone memory,ram is much faster than nand i think..hastarin and even darkstone stated it..!i think cotulla also i agreed..!i made benchmark scores with nand and was 1400 on dhd and 1200 on stock desire while ram desire stock gave 1700+..neocore on nand is 30.7 fps while on ram is 31.6fps !i tried games on nand such as asphalt avatar nova and lags while on ram dont!overall nand is great for those who want to get rid of winmo!battery is a bit much better on nand
thats all from..i suggest people try nand..its great!it is very easy to install and if you are not like it...it is very easy also to boot back to stock or custom winmo roms!
thanks cottula for all this and the devs for making all this possible ..have a happy new year

I think I have to find some other ROM for NAND, DFT LEO Stock NAND Android is running too many junk HTC app's and services in the background.
I have leo1024 and currently running running on a SD build. I was thinking about switching to NAND, but had few questions prior to switching.
Is the NAND build worth switching to? Is it faster? Does it consume less battery? What are the disadvantages to switching to the NAND build?
Also what is the best clean froyo NAND build?

It could be a good move to compare two same builds (Nand and SD)
like :

and stick this if ready.
It could stop many questions about what is better.
Thanks.
I can only tell you my experience. One of my biggest frustrations was that if I locked my phone by pressing the red end button, and tried to turn the screen back on right away, I had to wait 20-30 seconds. That no longer happens. For battery, the lowest I ever saw was a 4ma standby, but usually closer to 6-8ma. I routinely see 2ma in standby, but probably averages 4ma...this is probably 25-50% better battery. It just seems more smooth also. Plus, with RMNET being as fast as PPP, there are no longer any data drops.
Again, this is my experience. Try it...if you don't like it, you can always go back to WM and SD card builds.

I have been on nand and all kind of recovery and app2sd and ++ methods. trust me SD based built is best one. you have more choice(window and android) and that is the speciality of HD'2'(2- means 2 operating system)
battery wise nobody can't boast about nand because any latest phones bettery(including desire HD itselt) is very bad . Also android drinks battery if you are not maintained your running applications properly.
furthermore no complication and less harmful to device.so better to stick with SD. Trust me.. in couple of weeks time all guys will turn back to HD '2' do you know what i mean...??
No way I will ever go back to windows + sd...
Nand is better in more then one way, smooth all around (as mentioned never unlock delay), better battery usage, faster downloads and installs (and no freezes when doing a market install)
If you are wondering why you still have windows on your mobile because you only see your android booting up, go got nand

Well, thats one opinion, ok.
Personally, I didn't try all kinds of recovery, didn't try app2sd, didn't try any ++ method stuff extra extra extra!!1!. Just didn't.
I just tried a few ROMs on NAND, and generally the user experience is so good I don't want to bother using SD or RAM builds.
The biggest plus of NAND is that it makes use of the device's hardware in the way it was supposed to be, without having the deal with Windows Mobile juckyness.
The battery life is dramatically different, because constant reading and writing from SD uses battery charge that isn't even monitored by currentwidgets. If you say 'any new phone has crap battery life' you probably only tested a rom with the 60mA after call bug. These eat battery charge just as fast as RAM builds do.
imagine what happens if you compare such a system to one that averages 4 mA
My father also has an HD2 and he is running a rom that still has the notification led bug thing going on. Still he gets 3 days battery life out of it!!!
NAND For The Win
NAND is the way to go.
I experienced lots of standby battery fluctuations on SD. After trying almost every SD build that made "battery saving" claims I honestly still couldn't reliably use any of them for day to day use. So I just stuck with Window Mobile.
After flashing to NAND I usually see 1-4mA standby. Even in poor signal spots!
Well seeing that you have that damned 1024 leo, you have the ideal device for android on NAND. Advantages for you:
You have a lot of free storage, prolly 500+ since you got TMOUS
Power consumption is low
Performance in sense builds, for me, has been better, especially with Desire HD builds.
Fast boot time
Disadvantages:
Not as much free storage as to what you can get from SD builds
MAGDLR and installing a NAND build, might pose some problems for you, if you don't read the forum...
If you like winmo then installing android onto NAND may be considered a disadvantage for you.
So I went ahead and tried out the NAND method and I kinda like it but I am confused about few things.
I have read throughout the NAND forum and people keep talking about AP2SD+ thingy. I am still kinda unsure about what it is, but I am guessing its to automatically install all apps onto the SD card instead of the device itself. Am I correct about this?
Also, is there a good clean froyo build? When I was using the SD card method, I used MDJ's Froyo HD 4.6, which didn't have a custom skin. I currently see that the only good NAND build by MDJ is the Froyo Revolution v.2.3. Is there a way to remove the custom theme and revert back to the default?
Also, I see here on the MAGLDR boot menu that there is an option of "Boot AD SD". I went to Services > BootSettings >> AD SD Dir and changed the folder to "Android" which is the location of build on my SD card. I manged to get it to boot, but it just get suck on the boot screen and doesn't load up into the system.
hey why not any one with two hd2 mobiles(one with NAND and the other with SD) make a video comparision so that people could really see the speed and effiency of both roms?.i think this solves the problem!..
i like nand better then sd
Apps2sd that is used in the nand roms stores the bulk of an application on an ext partition on your SD card. This in effect gives you a ton of space for apps.
Nand builds for me work great. Battery life is better than even winmo was, and there aren't any glaring issues remaining. Its becoming very fine tuned in the nand forum. I can't speak for SD builds because I abandoned them a long time ago. You can always flash winmo back if you dont like it.
Sent from my HD2 using XDA App
as far as windows mobile is concerned its good with battery backup but if i choose between nand and sd i would have gone for nand as its really smooth and without any cons in some built and its going great with provide me better application and a lot to choose without any lags.so a liitle compromise in battery is ok for me though new nand built dont have the battery problem either.Except in few people complainig about battery issue that must be because of wrong installation or their luck
I kind of SD ....
I changed to SD from winmo recently.its smooth and no response problem yet.SD has the advantage that ,I can just go back to winmo on a reboot in case some thing goes wrong with green.I recommend SD at least for beginners.Once you are Ok with it > move to Nand if you want so ....

Use CWM, the advantage with CWM is that you can backup your NAND build, try other builds, even revert back to winmo if you want, then come back and restore you backed up android and its all back to how you had it, awesome
I have a LEO512 so I stick to Cyanogenmod and MIUI roms, I would like a really nice updated desire rom, but everyone seems to have moved on to desire HD and left the desire rom by cotulla behind, which is a shame because I have issues with some APN's with that build. I've never ran out of space and I don't use app2sd, but maybe I just don't use as many apps as some people.
I used to get sleep of death issues with all SD builds, now I dont get it with NAND, thats probably the best reason to move to NAND, instant wake up.
NAND offer way more functionality, a few appd I've played with wont install on SD android, angry birds is a perfect example, running NAND thus far has no limitations, MIUI has some very stable roms with alot of additional functionality that stock android doesnt

So I have been searching the forum for a while but haven't been able to piece together a good answer from what I have been reading, so I decided to go ahead and ask. I know that these questions have been asked before, more or less, but at the rate development is going, and with the updated Android builds, I would guess things have changed even from 2-3 weeks ago, let alone 2-3 months.
What are the advantages of a NAND build (nowadays anyhow) over SD? Is it the speed?
Is battery life better on NAND or SD or it is really up to the kernel?
Are RAM editions somewhat speedier than their counterparts? if so, are they less stable or something than a regular NAND or SD version? I mean, if they are equally as stable, why isn't every developer doing RAM versions to get the most possible speed?
I know the speed of the SD card helps with SD versions to some extent. I bought a 16GB class 10 Wintec for that purpose, and it seems to do well. At that point, battery nonwithstanding, would be it worth it to go to a NAND build or would the speedy MicroSD make up most (if not all) the difference?
Thanks for the answers in advance. I just wanted to get a little bit of updated info from those in the know
While I am at it, another question to add to the list.
Does the underlying OS make a difference with the SD build? I know that Android should shut down and supersede the WM drivers, but would having WM7 over WM6.5 as the underlying build make any difference whatsoever to anything when booted into Android from SD?
thanks!
Main advantate of NAND is that you can replace SD card without turning off phone. And your build don't rely on speed of SD card. But due to small storage space, many builds still use SD which kinda defeats it's purpose.

No one has any idea on the other questions? Thanks for your input matejdo.
Again, some info is appreciated.
SD/RAM/NAND?????????????????????????/
I would really like these questions answered too.
I know that so far NAND is more complicated ....
with 2 or even 3 partitions, from EXT2/3/4, < who knows which is best.
And NAND is not as fast as RAM obv but is much safer in regards to corruption.
I have found SD builds to score higher in flops and quadrant than NAND however which is strange. SD is easier to copy to device, other than that im sure all custom roms have their issues. including screen light on lag.
i have tried and loved darkstone ram edition which was rapid but just not all there is you know what i mean, and now after giving up on dandiests desirez3.4/5 in nand and sd after too many lags, crashes and data drops etc im looking at MCCM HD V4 or MCCM GB1.8 SENSE GINGERBREAD as these seem to be the most stable build with all functioning functions but i shall soon see how they fair.........
.............................greatest respect goes to all devs for you efforts
we're nearly there!
but please any input regarding these questions would personally b appreciated!
Ok, here's my 10 cents. Some of this is debatable but these are pretty standard answers.

Battery life is typically better on NAND. Kernels can also make a difference.

Technically, RAM editions are faster but they are worse on battery life. Data stored in RAM requires constant power and does not survive a power cycle of the phone, therefore the data is stored typically to SD card, which also consumes more power.

They say NAND write operations take longer than an SD card but for the life of me I still find it faster when a ROM is running completely off NAND than off NAND and an SD-EXT partition. Or, NAND versus full-SD- there is a huge difference in responsiveness between read speeds. They are much faster on NAND than even a fast SD card.
Hope that helps...

It can be more complicated... until you do it once or twice and fully understand how it works. Now that this has all been out a while everything is starting to standardize and more and more ROM's are using the same partition layouts. From a performance perspective there really isn't anything noticeable between EXT 2/3/4.
Oh, most ROM's now also use CWM, which along with an SD-EXT partition can leave you with up to 7 different partitions on your device. Fortunately, you don't really have to manage any of them as the ROM's do all the work once you've set it up once.

This is due to a slower write speed of NAND storage versus SD storage. But, because the read speed of NAND storage is higher you still get an overall feel of greater responsiveness and speed even though the scores are lower. NAND ROM's are easier to backup and manage via the CWM aspect.
I mean, if they are equally as stable, why isn't every developer doing RAM versions to get the most possible speed?

Possible problem may be higher amount of RAM needed. Especially sense builds would need a lot of RAM.
I have to disagree with a lot of what the post above mine said... The main difference between NAND and SD builds is with NAND builds you can use clockwork recovery, remove and replace your SD card while booted in android, and maybe a few other small improvement in stability and performance, but nothing too noticeable. Speed and battery life are about the same. You might get a little better battery life on standby with NAND. I generally got 3-5ma drain on standby with NAND, while I get 4-6ma on standby with SD. Speed and performance are pretty much the same because when you're running something with either type of build, it does it from RAM with either type of build. When an app or a process is running, it goes into ram, regardless of where the info was stored. NAND and SD are just the 2 options of where the data is stored when it's not being used by ram. Actually, the NAND in the HD2 can be slower than the NAND in good quality SD cards... but the random access speed is good in the HD2 NAND. But with a high quality SD card, you can get just as good random access speed with SD. That is what makes the performance difference with different SD cards... when the OS is trying to access small amounts of data or write small amounts of data, different SD cards will take different amounts of time to access... and the class rating of the card has nothing to do with that... in fact, class 2 cards tend to have better random access times than class 6 or 10.
But anyways, if you have a good SD card, performance and battery life are about the same... depending on the build of course. Desire HD builds tend to run a little better on NAND... but some recent SD DesireHD builds are good, too. AOSP and CM builds run pretty much the same off of SD and NAND as far as I can tell.
RAM builds work by loading more of the OS files into RAM at startup so that the random access speed of them is improved greatly, since RAM is the fastest memory and where any data is loaded to run anyways... it cuts down on the need to access the SD card for as many small system files, which improves performance and battery life in theory. The RAM is used anyways, so it doesn't use any more power keeping extra data in RAM, and since the SD card isn't accessed as much, it saves power there. But SD doesn't use much power anyways, so it's not really a noticeable power reduction. Also, RAM builds are still pretty experimental, and can have problems with data corruption... if any changes made to the os are not recorded to the SD, then if you lose power suddenly, there can be problems. Also, keeping all those system files in RAM causes you tohave less RAM available to run other apps and such... thats why there's no RAM builds for DesireHD builds, because there's not enough RAM. Personally, I never noticed too much of an increase in RAM builds performance compared to other AOSP SD builds like JDMS. Also, I'm not sure why, but I don't think RAM builds worked very good with NAND. But in theory, the system files in RAM is a good idea, especially for SD cards so it takes some stress off the SD cards. When running a build off SD, your accessing the SD to read and write system files while also accessing it as normal to run your apps or play your music or other data you have on SD. Keeping system files in RAM cuts down on the work the SD needs to do in the same way installing android to NAND does... then the SD is just used to access your media files or apps or data.
So in the end, it all depends on what you want from your phone... if you are not going to use winmo or wp7, and only use android, you might as well put android on nand, even if the improvement isn't that noticeable, because you can then use clockwork for easy updating or flashing roms, and you can change out your sd card, and there may be other small improvements. But if you still use winmo or wp7, then you have to decide if it's worth losing the ability to run more than one OS to give your android the added functionality of clockwork and other improvements. I use android on NAND for a month or so, but I didn't like how it turned my phone into just another android phone... it couldn't do anything that you couldn't do with a desire or evo or other android phone. But with the ability to run winmo or wp7 also, it's the only phone that can do it this well. When wp7 was released for the HD2, it was perfect for me because I wanted to try that OS out, and now I love that OS almost as much as android... I would have a hard time picking between the 2... luckily I don't have to. No other phone can run both of those OS's, either... I feel like I'm really making use of my HD2. If I just wanted android, I would've bought a native android phone from the beginning. But the great thing about the HD2 is no matter what OS you want, the HD2 can do it. People who want just android can make their HD2s almost like a native android phone now that it has clockwork recovery support. People who want 2 OS's can do that too. Android runs great from both SD and NAND... so use what works for you.
the battery life in android roms, is better than original windows mobile?
speed battery and efficiency are the main reasons
Yes it has a beter battery life (imo)
Ram is faster memory wich will make everything very fast, but you have to fuzz with Windows Mobile (?) to get there and that is what people dont like, the I/O on RAM is very fast, thats nice and makes quadrant scores very high
Class 10 card is good for SD versions, but imo that is very outdated, NAND is the way to go, like real Android devices loaded from the phone memory, not ram or sd, wich gives a beter battery life and fast speed (almost like stock) .. and also important , no fuzz with Windows Mobile.
And rest of the data wich isnt on your phone mem can be get of your SD card with a NAND version, cause the phone mem doesnt have rly that much space left after u installed Android on it (enough for enough apps though), class 10 mostly means a faster speed, so it will benefit you in some way

No offense at all, but I really tried to read your massive wall of text but I got lost after the first sentence.
I beleive that the custom android roms do last longer than original winmo. I love this 2.3.2 rom on my HD2. 2.3.2 on my gf's mytouch 4g last about 18 hours on moderate call/text/ use with overclocked on 1.3

for ex in win mobile, using the hd2 moderatly, how long the battery survive? and in android?
Wow! Lots of great info here!
I have been playing back and forth with different OS's and builds and SD builds and NAND builds etc. My phone is probably screaming at me to give it a break
As per responsiveness, the NAND builds (non-sense) seem to be a little snappier than the SD ones for me. The battery life seems about the same. Haven't had a problem with NAND space as I bought a US HD2 with 1 gig of ROM space, which is plenty for me. I haven't actually delved into the WM7 yet, but after reading this, I think I might give it a whirl and see what happens.
The biggest difference for me between the Android Nand/SD builds was the initial loading times. Which makes not that much of a difference because I tend not to turn off my phone anyhow.
The 2nd biggest difference is the wake from standby. On almost all the SD builds I tried, I would hit the hangup button, and the screen would come on in like 1/3-1/2 a second. If I accidentally hit it twice, I would have to wait 3-4 seconds for it to work properly again.... more presses seemed to do nothing. On a NAND build, it seems like the screen comes on instantly, and does not have the repress issue. But, then again, this is not a big issue for me at all.
The fastest build, by far, that I have tried so far is the Hyperdroid v5 build. It really does respond faster than almost anything I have put on the phone.
Thanks for all the answers people! It really helped to fill in the gaps in my admittedly shaky knowledge!

Yeah, sorry about that... I tend to try to fit too much info into a post all at once and I sometimes don't organize it well. I'll also ramble on sometimes to get everything out I'm trying to say and it ends up making the reader miss a lot of the important parts.

i understood it quite well..i think u have alot of valid points.. There arent big differences between sd/ram/nand...its a matter of choice imo..

if its on sd card it will still load into android after turning off everytime right? i dont want to see windows anymore at all

Thank you for your post it has the best thought out points for and against, and greatly helped me in deciding which build to go for.
i want to know which is better the Nand method or the SD method,which is more stable to put on my htc hd2,thing that i want to work for me that are must are the mms/sms send and receive,the cam and the wifi-and to be able to close the apps and not have all of them running when i start up the phone also i was haveing a problem everytime i turned the phone off then put in the wall charger it would just turn off,if one could point me in the right direction in to which is betterthat would help,as well as direction on to install either one SD/NAND METHOD.thanx a mill
personnally, i noticed a huge improvement when i switched from sd to nand. incomparable.
far better, all aspects. no more disconnections, better battery life, less lags, i donot regret winmo.
My favorite rom is sergio's team core droid rom series for all the fancy effects and, of course, the swiftness.
I did not even try other ones, and tiped the team. but i'm sure others will tell otherwise.
I would agree with the above poster. Going from a SD build to a NAND build, the NAND build is much smoother and uses less battery. The best I could get on standby on a SD build was 7-9mA and actual use from 300-450mA. The NAND build uses on standby from 2-3mA and actual use from 125-300mA. If you are a TMOUS, then you should try Cmylxgo's Desire HD(2) build. The build addresses everything you are asking. It even uses an optimized gps.conf file to lock onto the GPS satellites quicker.
do you have the link for that one Cmylxgo's Desire HD(2) build.cuz that sounds like you said address all my issue

I've couldn't really tell a difference between NAND and SD as far as performance and battery life. I got 3-5ma on standby with NAND, and currently I get 3-6ma on standby with SD builds. No noticeable difference in performance. The nice thing about NAND is having clockwork and being able to change out SD card. Also more builds available for NAND now. I used NAND for a little more than a month, but I felt like I took away what makes the HD2 special and unique and turned it into just another common android device like everybody has. With android flashed to NAND, the HD2 can't do anything that an Evo can't do. I was thinking about going back to WinMo because I still liked using that sometimes, when WP7 was released for HD2. After trying that, I couldn't be happier with my HD2. What other phone can run 2 great OS's almost as good as the native phones can. I now use both WP7 and Android about equally, and at this point wouldn't be able to decide between the 2 OS's if I had to get a new phone. Luckily I don't have to pick right now with the HD2. I don't think we'll ever see a phone as versatile as the HD2 is again. Hopefully soon I'll be able to boot WP7(nand), Android(sd), WM6.5(sd), and Ubuntu(sd) all from my hope at any given time.

ok so i flashed a rom useing the nand method the problem iam haveing now is that wheni turn the phone off to charge it.and put the wall usb in the phone comes on,as well the when i got to the task killer app just about all the apps are open some are open that i never even touched,any info would help

With magldr, you need phone on to charge. It will automatically boot when plugged in. You must charge with phone on.
And some apps do things in the background without you doing anything. Task killers aren't actually needed in android... they usually mess things up more than helps. Android is good at managing memory on it's own.
