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)

i dont know what you did but for me you are wrong! flashed gauners build i am more than happy! fast stable fast market downloads! everything that could somebody want from an android build.. and i use igo on that build wich also works like a charm!

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.

Gotta second this!
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] Everyone says "fast"... but actually theyre not?!

Hi there,
Currently i'm using a SD-Android of MDJ.
Because of laggy animations i would like to update my current Build.
I've read through several NAND-Threads and nearly everyone says "fast fast fast".
This:
http://forum.xda-developers.com/showthread.php?t=877777 NAND looks very interesting, but after looking the Youtube-Video ( http://www.youtube.com/watch?v=4Ab0ztDxibo ) there i'm a little bit confused... The UI looks nice, but it's lagging as hell there! - OK, it's not like "Ok, i started the app, now i can make a coffee", but the animations arent smooth... There are SD-ROMS availible which are smoother!
Is this behavior normal?
Is there any fast Android ROM, SD, NAND, RAM, etc?!
The only thing i want is a Build, which is:
- nearly stable
- fast
- small (to maximise user storage, but i dont need that much, just a few apps and Mails!)
- without "Not working in this build"-Parts
Greetz and thx for helping!

Try Darkstone's SD-RAM build, it's really fast ...

I do know 2-3 SD-Roms which are very fast, but i want to get rid of WinMo, so i need another solution
SD-Roms are still "Workarounds till NAND"

Please post in the right section.
Darkstone's build seems to be the fastest at the moment, closely followed by Markinux's builds. MDJ's gingerbread builds are getting there. I find if I set the governor to OnDemand and OC to 1300MHZ, most NAND builds become as fast, if not faster than my benchmark Desire HD.

I was skeptical about NAND at first, I thought "what's the point"
BUT, all I can now is WOW! WOW!
NAND is 4 million times faster, smoother a a lot more than SD builds

Joined in 2008, 269 posts, yet you clearly post a question in the developers section, ignoring the Android question section
BTW, it depends if you want a sense build, non-sense, gingerbread, desire, desireHD etc etc. Each has it's positives and negatives. The slowest of the lot are the DesireHD builds.

Thx for your answers!
Sry for wrong-Posting the Thread, well i'm a little bit tired
Well... I do not need Sense, and i do not need Gingerbread, all i want is a fast Android build

Your given example NAND is experiment, testing NAND, Can't compare to the rest.

So is there no NAND availible for daily use?

I think you mean, stupid fast, I was using this before I went NAND, this was definitely faster than NAND builds.
This ROM is also stable enough for everyday use. If you are using Sd though, just install-backup-change-restore, is easy with titanium backup, just try a few ROMS until you find the one you like.

But i think NAND Roms do have a better battery life, right?

I've been using my NAND build on a regular basis since it came out. Haven't been back to WinMo since NAND was first offered. For me the fastest NAND ROMs are TyTung which I would rank as best as far as speed but its completely Stock. I've also tried cmylxgo and his is pretty speedy as time goes by...I'm actually using that one right now and its been running for 4 days with no issues. Got like 60+ apps installed and using ADW Launcher with a theme and loving this build. Might go back to Gingerbread tho after another week cause I have a problem staying on one ROM too long lol...
Haven't tried MDJ ROM but Im using his kernel and no data issues and market downloads are insane...may try his GB build out...
Also heard DarkStone build is crazy fast which is a plus too...

Have been using my HD2 1024 for past 3 days and love it. ATM have miui but its okay, dont like interface much. Tho I must say, every nand rom was laggy for me for first 5 minutes for sure. Then once you set it up, fix things up, do few restarts, the phone gets super fast. Like really fast. Unless you have ****ty laggy hd rom.
atm trying darkside rom

i am using mdj revolution hd sd version for over a month now.daily usage that is.i have a great battery life and its fast.i think its one of the best sd version.like the animations,recommend it.

Just installed darkside 5 mins ago. No lag at all so far.

:O Got rating of 4000 WTF :O
Thats on darkside nand rom

Hm...It seems everyone prefers another Build (and technique)
I've tried to setup setCPU on my current build... looks smoother till now, maybe i dont need to update that fast... maybe i'll wait for "the ultimate super fast and stable NAND ROM"

Thats not darkside, it's Darkstone1337.
#2
The build is called SuperNAND.
#3
It's an amazing testiment to the advancement of NAND/RAM developments by Darkstone1337, but not stable enough (yet) for daily use.
#4
To the original poster [infernalshade], I would recomend reading some posts 1st
That's where you're going to find the most indepth information on what's working & what's not in a certain build. Before you post, search search seach & search again. Most times it just takes some quick skimming thru all the pages to get the jist of things.
#5
Try it out. Sometimes stuff just works better on different phones, call it 'The Ghost In The Machine" or whatever. Besides that, who cares what anyone says if it doesn't suit you and your end needs

Happy Flashing !

Most of the ROMs I've used are faster than SD builds. The Gingerbread ROMs are fast. The Gauner DesireHD is as fast as the SD builds of the same version of Android. But it does require getting through setup and a few reboots thereafter to smooth out to WP7 smoothness. However, every DesireHD ROM I've tried boots up super slow. That is where the SD builds excel above the ROMs.

its cm7.theres no stable build for cm7. its still laggy and buggy. cm6 will be less laggy and glitchy

[Q] Best Android 2.3 ROM for HD2 YET ?

Hello Folks,
Right now I'm using wildfire, but I don't like it any more. I'm planning to switch to HTC HD2. how good is it ?
More over I'm no more impressed with Windows Operating system available in it (W 6.5). I have gone through some positive replies and videos on HD2 running Android 2.3 (Ginger Bread). So please help me out to find which ROM will be fast good enough with less issues to use on HD2.....
I'll be waiting for your valuable replies !
Thanks in advance

Android runs perfectly without any performance issues for a longer time now.
There are a lot of roms in the Hd2 Android-nand section which are running without any bugs.
Which fits to you you have decide yourself.
I would recommend you to have a look at typoon(look at my sig), hyperdroid and nexusHD2..think thats a good start to begin with.

you would be best off getting a native android device

Go for a native android device
Of course there are some nice Android builds for HD2. BUT, nothing is perfect. For example I have these two issues that are not solved in any build.
1. The speaker volume (ringtones, notifications, music) is very low on android compared to windows mobile.
2. Whenever you press the wake up button the screen comes up only after 1 or 2 seconds.
So there are some issues like these. So better go for a native Android device.

I would have to second Pongsters Hyperdroid CM7 newest build. The only thing you need to do is replace the stock camera with another. Like the MIUI camera or the LG camera.

These issues are solved in some roms:
The sound is related to /system/lib/libaudio.so & /system/etc/firmware/default.acdb
I forget what the wake up lag is related to (Sensors lib i beleive)
I use a personally modded version of CyanogenMod-7 to run on my HD2 and don't suffer from your problems!
It does depend which rom you are using but you should be able to patch/replace those files!
Hope this helps

Hi....
In my opinion the graphic glitches are annoying in current gingerbread roms (as much as I experienced)... I use Desire DL roms from SD, but I'm looking for a relatively bug-free rom with htc-sense to flash instead of WM 6.5 and run android directly.... I'll be honored if someone could recommend me a rom, running as fast as possibe with least bugs, and specially without delay after installing applications or waking up on calls....
Thanks in advance...

Use official Miui from Miui-devs.com. Rom updated every week, if bugs are found, they usually get fixed with-in few days or in next weekly built.
so far i have no bugs. other that common signal bar issue that most in not all users have. Sense 2.1 ROM was also bug free for me.

is it true that running android via NAND has less battery consumption than via SD ?
cos I run via SD and the battery drops like a %every 2 minute...if I am on wifi...

laggy, choppy, slow response?

Hey guys,
I just dual booted my hd2, super fruit 7.5 and cm9 ics nexus SD build, and I don't know if its just me, or if I was expecting too much, but the android portion is very laggy and slow to respond. Even typing is slow and laggy. Is this just me expecting too much from an Sd build? Or is there maybe something I did wrong?
Spl 2.08
Radio 2.15.50.14
Maglrd 1.13

And Also when in windows, the earpice and speakerphone volumes are extremely low even when turned up to max.

12.Aug.2012 MAGLDR/SD NexusHD2-ICS-4.0.4-CM9-HWA-SD V2.6 is the ROM you've installed, isn't it.
I would at first try all recommendation of members in that thread which reported same or at least similary issue before starting a new one.
Short wrap up what you can do, update initrd.gz, increase sd speed, limit background process, increase cpu, format your sd card and so on.......you have to play with all of these parameters.
For most of all these actions you can use RomToolbox pro.
If you're still suffering maybe you try another build, again some people get the build running smooth some not, even the set up looks same on the first view.
I have alway's 2 or 3 builds on my sd and try them under normal conditiion, which means for my daily work, which includes phone calls,SMS, data/WiFi usage to justify which build to use at the end.
Good luck :good:!!
Cheers.....LinChina

I believe we entered the era of laggy semi-functional ROMs post-Gingerbread. The last time I had no problems, lags of FC and the ROM felt stable and reliable was over 6 months ago. Can't honestly say which ROM worked as expected, no matter the title or description promises, so if you want to go with ICS or JB (even less functional), find the ROM you can live with without expectations of full functionality or lag.

[Q] JellyBean - why so laggy?

Hi. I know that it is a noob question, but I am wondering why JB builds are so laggy. They should be smooth. I don't mean performance, because that one is great, but overall interface is "heavy" and laggy. Eg. statusbar line (this one we slide up and down), switching windows etc. Scrolling is great so why these stuff aren't so? And MIUI Jellybean: I know MIUI as the smoothiest roms, but JB edition is a nightmare. I understand that these are early builds, but not so early :/

Did you tried the NativeSD releases or the NAND ones? Which class does your SD Card have?

I've tried both of them. My SDs are 4class and 2class, which 2class (about 18MB/s read in Low Level Benchmark in Flash Memory Toolkit, and about 1.5ms access time) is better than 4class, I think 4c is just dead. And transffers and I/O is perfect, but animations are sharp, like the GPU was weak, but it shouldn't be SO weak...

I agree with him, and it's not a matter of NativeSD or NAND. Jelly Bean just doesn't feel as smooth as Ice Cream Sandwich, even though it has hardware acceleration. That's why I'm sticking to ICS atm.

i really dont know what yall use your phones for but i use the roms in my sig

Well admittedly I only have experience with one JB ROM on my HD2 (the one in my signature), doesn't feel laggy at all to me, in fact it's pretty zippy, and consistently so. I have OS on NAND and programs on ext (class 10 SD card). It's a rather mature version. I read that MIUI is also no slouch. Could you possibly have had a faulty install?

I have the some problem with the lag. I use kovjanos' PA ROM with the pure PA framework. Everything is smooth and fast except for the window and framework animations. When I open an app the opening animation lags and if I pull down the notification drawer, it seems like the drag bar "stays behind my finger" so it follows my movement really slow. The usual display-off animation doesn't work either. I tried different 4.1.2 ROMs and had the same thing everywhere, no matter NAND, NativeSD, or DataOnExt.
I tried the evervolv 4.2.1 as well and it works perfectly, all animations are smooth without any lag.
I think it might depend on whether the ROM is compiled from source and with which device tree, or whether it is ported from an other device and which ROM was used as a base.
