[Q] HTC HD2 running android.

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?

It was near the top of my unread threads page? Somebody replied to it, not me and I found that nobody answered the op and were instead discussing the pro/cons of NAND vs SD.
Sorry that I didn't check the date of the thread before posting.

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.

The rush to NAND, what am I missing here?

Since the first NAND build almost everyone here in the forum can't stop talking about it.
Am I the only one thinking, why do one need it?
- it makes no progress to functionality. We had everything already with SD builds.
- Switching between build is now longer and riskier.
- One needs to commit himself to a build because it won't be possible to jump from a sense to a stock, or from froyo to gingerbread with a single boot.
For example MDJ's gingerbread without GPS can be quickly switched to a full working froyo.
- With SD build one can take full potential of the storage on the phone. With NAND system size is limited and one can't install unlimited amount of apps.
- So boot time is longer with SD builds. Come-on got to be some other reason to move to NAND.
I open this discussion for people to enlight me what am I missing when I ask for SD builds.

Maybe u should take a look at the NAND pro and contra thread.

I fully agree with you. I don't really understand the interest for NAND. It boots faster for sure and drains a little less but compared to the advantages you mentioned of sd card or even ram NAND is not for many people.

Aside from the battery life and faster boot I think most of the desire for Android NAND is due to the dislike/hatred of windows mobile on this phone.
HTC produced a stunningly specced phone and then slapped windows mobile on it with no option to upgrade to win phone 7 or sidegrade to Android, and a lot of people see that as a bit of a slap in the face. I certainly do. Stating that there will never be an android build from HTC for it and then producing the EVO was a bit disrespectful of customers.
Also there is the (for me) a slight feeling of im-permanence of the SD builds. Yes, they are great and its fun and useful to be able to switch between them at will but the nand versions just feel a bit more solid, if you will.
A lot of it is down to human nature rather than actual technological benefit, sort of a "Hah, you said we couldnt do it but we did, so forget you". (With apologies to Cee Lo Green).

I dont get it why ppl make a topic only to whine about NAND. The devs put so much hard work in it and then they see topics like this.... plzzzzz
If u dont like it ... dont use it ok ... or buy a native android phone

They didnt get enough hugs as a child??

As stated before it has many improvements over the SD version:
-battery life
-stability
-loading times
-there is no risk in bricking your phone(unless someone is very very stupid, and i am not saying that someone is)
-with the sd version a download from the market sometimes took 2 minutes, now it takes max 2-3 seconds.
-flashing back to winmo if you like is maximum 5 minutes
-flashing a new android takes max 5 minutes(MAX).
- no lag at all
I am sure there are more but this is what i could think of right now.
Try and you will see.

Seriously.. Why wouldn't you like having more options to choose from?
If you are afraid that devs will stop developing for SD builds, then you shouldn't be.. There are enough people out there staying with SD builds.
I just don't like the sluggishness the WM-boot gives me.. It adds another layer of uselessness to me, as I don't use WM anymore at all..
I love my HD2 running NAND with the HTC Desire HD build of gauner. For one, I don't have to be messing around with SD mounting and unmouting anymore. I hate the fact that the main OS actually tuns off the card that you should use as swappable storage, which it was introduced for.
Everyone is entitled to their respective opinions, and there is no harm in having more to choose from.

+1 on that. I'll be sticking with SD builds for the foreseeable future. At least until Android is perfected. The Gingerbread build doesn't even have working GPS or camcorder and is NAND. That, to me, is ridiculous.

I know its been said enough already but the clincher for me was the improved battery life. I just got a full two days with phone usage (light) SMS usage (heavy) and WiFi usage (heavy). That really was a breath of fresh air in the world of 12 hrs SD builds.
Also, i think people were right to point out a lot of draw towards the NAND build has been a reaction to WM6.5. The OS was seriously lacking and was a poor choice to put on such a capable device. It lacked the real functionality of a smartphone which seriously hampered the HD2. With android the phone seems to get a new lease on life and i am quite happy in keeping it for another 1 year.
Although it is early days for NAND builds but i am sure with the passage of time their obviously advantages will be apparent to all. Although SD build do give you fast switching but seriously it becomes a pain to keep switching and then backing up and restoring all your data and applications. I have been there and done that. Atleast with a NAND build switching is prevented and stability is creeping in.

You missed out No Windows Mobile I really dont get this Thread,The guys have been workin on nand for months so that we can eliminate the problems we had booting off SD ,Nand has made things a lot easier now that we no longer have to rely on Windows,Ive been testing it for a day now and its fantastic,a hell of more stable and you can use every day

It depends on which SD build you were using. The ones in my sig are top-notch, fully-functioning and daily-use stable. The battery life is excellent.

Can someone confirm this. It seem rmnet is not stable at edge connection. The data arrow always gone and then it reconnect again. Happen with me couple times when I was browsing internetan

Right, but Almost all my SD did not boot correctly with MagLdr
My experience with nand is FASTER A LOT, drain less battery, no lag at all (except on my old hd2 (probably broken, no proxymity detector, no more vibration, volume key works bad etc.) that lags more than with the sd card (I had to revert to win)).
Mag is a LOT Faster to download/install apps. (50kb/s now its 400k/s and installation is faster), smoother.
Because now, I can change my SD card whenever I want (Full of taken videos/photos with the phone, full of mp3 etc).
Why nand, because Lock Phones utilities are useless with Windows.
Why nand ? .... Because !

There's a few factors to consider and these can be deal breakers for some people.
1. The version of the HD2 running a Nand version. T-Mobile US phones get more space to play with whereas the Euro version doesn't. I've got a US version but I really only use 20 or so apps.
2. Data - Since downloading Topia HD last night, I had one data drop running from Nand and that was opening market. When it was SD it was constant!
3. Battery - some people are reporting excellent battery life on Nand. But they reported that on SD versions as well. Everyone has their fixes for it too, but it doesn't work for everyone. Right now I seem to be doing ok so we'll see.
4. Risk - its less riskier than flashing HSPL or a new ROM in WinMo which brings me to my final point and deal breaker for me.
5. It's no longer running WinMo!!! For me that was what I was waiting for. No more gimpy OS ruining my phone. I know a lot of people love WinMo but I'm not one of them. I almost gave this phone back when I got it in March of 2010. It was frustrating and by my 1st week of owning it I had done 3 or more fresh resets. After that I did a reset almost every month until Android became stable to run everyday. I say good riddance to WinMo finally lol
In the end, its about preference. My preference is a phone with little or no hassle and huge functionality which I now get with Android and especially now with it running from Nand. If it was still running from SD or RAM I'd still be ok as long as it wasn't WinMo.

One big issue with NAND, that is being overlooked, is no support right now for WinXP. The magldr seems to be flashable only in Win7. There are a number of people who still don't have Win7, myself included, and are still on WinXP.

Are you still on XP by choice or becouse of old hardware / no budget for new OS? if your still on XP becouse you dont wanna go Win7 i only have to say Get along with the times. I would say a update for windows XP and Vista would come sooner then later.

why went back to sd built from NAND?

Hi guys,
While I am respecting and thanking all devs for their hard work and time , i would like to share this thread with the guys who are not happy with nand and went back to window rom with sd card based android built. and the reasons for that
I used NANDroid for the last couple of days and felt missing something. From NAND i did not get big advantages as expected.
reasons are (please do not get offended this is my personal experiance)
1.nandroid internal memory is not enough to save lot of applications
2.Even after Data.img is created in some builts using app2sd it is too laggy, i feel the lag in SD built is better than NANDroid
3.what is the point of using android alone as i could buy a cheap wildfire for £100 brand new handset.
4.some applications can not be ussed in ANDROID like tom tom and Garmin( i dearly miss TOMTOM as you all know NO.1 SATNAV in Europe
5.whatever we do the HD2 hardware is not fully support to NANDROID like native android as this phone is designed for windows
6.some SD builts like mdeejays desire HD 4.6 and cedesmiths desire HD and darkstones superRAM are better equiped than NANDROID.
7.if I use SD build android it will be 2 in 1 and i can get both experiances.
those are the reasons i went back to SD card based built which is Mdeejay desire HD 4.6.(cheers mdeejay)

hi friend
I was using that before but when you install more than 10 apps from market or back up you data you will get warning 'low memory'.

Got to disagree with you OP. I think NAND is the best thing to happen to the HD2 since android was first ported. Im using HD2one build and it freakin awesome. The battery life is also spectacular, especially in standby. Can now run a full working day (9 hrs) and still come home with 60%+ battery life, with SD i was lucky to come home with 30%. Just my 2 pennies .
Ricey

I don't have the ability to try out the NAND ROMs (broken microUSB), but I am still thrilled that it can be done by others, if only for the renewed dev interest in the HD2, and more options for people is always better. But even if I could flash an Android ROM, I think at least for now I'd stick with WinMo and SD builds (more options is better). But surely with a little time, the NAND ROMs will surpass the SD builds in terms of stability, usability, and performance overall. Once we can flash Clockwork Recovery, and use ext2 a2sd, NAND will beat SD hands down. But even with that, having WM plus several Android builds and Ubuntu on the SD is a very attractive option. For me, multi-functionality will be preferred to stability and battery life. But to each his own, more options is better. I just hope the SD builds don't fall by the wayside, they still have alot of use left in them, and for those like me, theyre the only option.
~HD2 Android~

I will most likely go back to my tried & true SD builds because you can't update these ROMs with new kernels or framework of desired launchers. And regardless of what anyone says about changing kernels, I can't do it because I have no clue what ADB is and nobody explains it.
My SD versions work just as good as these ROMs and boot up in 1/3rd the time. I kid you not, it takes on average about 4 to 5 minutes to boot the Gauner or cmylxgo ROMs. And there is no stock m-deejay DesireHD ROM.

I can see the problems of the original poster as I'm in the same situation. The gauner build is nice and all, uses little battery and is snappy enough, it is lacking some important features (like led notifications). The speed difference is not as massive between nand and a fast sd build. Gauners build is just a bit snappier than mdjs Froyo HD 4.6, but the difference is hardly worth getting rid of the advantages of an sd build in conjunction w/ Winmo.
If m-deejay did a nice NAND build of his 4.6 I'd flash it right away, but it's nowhere in sight. First reason would be a fast and snappy, stable ROM.
Soon I'll go to a roaming country that I've got Tom Tom maps for, and I don't have igo. So I'll likely flash Winmo back and get back to MDJs HD 4.6 sd build.

A week ago I thought the same, using an EU HD2, you get half the internal memory of the US phones, tried a couple of recovery roms now using Jaws MUIU recovery and all I can say is WOW...a little confusing at first setting up your sd card partitioning and the setting up the recovery bit, but once done everything runs fast, slick and reliably.
I really did want to stay with windows mobile as I thought I didn't need android, but now I have android running so well I don't miss windows anymore, best of luck with your hd2 the best device

I'm back to SD purely because of the dual operating system, I find that making a call in poor signal areas wm is much better prob because it was designed for the phone.

This NandRom absolutely ROCKS!!!! Do yourself a favour and try it!!
Concerning TomTom: I do agree.. TomTom is by far the coolest Navprogramme, but Navigon for Android is actually quite good too..

Wtf lol....
NAND with data.img is much faster as a sd build,logical also:
You can see it as a pc with 2 harddrives in it,1 for the os,1 for writing data on it,so disc 1 keeps his speed (nand is this case)
I have zero lag using this method with the nand build that i use,and i am getting easy 2100 quadrant score on 998mhz ghehe.
No way that sd android is faster

[Q] NAND vs. SD vs. RAM builds of both. Speed and Battery life?

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.

Yes, speed, responsiveness, battery life, etc.

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.

Previous answer is why, more power consumption, data stored on SD.

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...

I know that so far NAND is more complicated ....
with 2 or even 3 partitions, from EXT2/3/4, < who knows which is best.

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.

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.

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.

[Q] which is better

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.

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.
