Ok, so ive been using android since around july from the stock nexus one builds, and then found my sweetspot with the Froyostone series with darkstone, after trying several Desire builds(which all worked very well). But after reading about all the advantages of the desire HD builds i went ahead and tried MDJs Froyo HD build. After booting into android, it worked well for about 30 seconds, untill it completely lagged up and was barely usable, so i continued with the setup anyway and got to the home screen (which took about 20 mins), then restarted, but this did not help at all.
Hoping that it was just this ROM, i tried several others, MCCM SE v3.4 and phiremod ACE, all with the same problem.
I never had these issues with any previous builds, any help would be greatly appreciated!
(Also has this happened to anyone else? I didnt see any other posts..)
UPDATE: I changed my radio from 2.15.50.14 to 2.12.50.02_2 and it seems to be running a lot smoother. Will report back, if this is a proper fix...
Did you create a HTC Sense account?
If yes, then your phone will be synced with HTC Sense (means: all your settings like games, apps, whatever will be backupped).
This can take a while and causes lags on your HD2. Otherwise you can disable it in the sync-settings.
Try it. I use the Desire HD build and its the smoothest i ever had.
Yeah I used the sense account on the first desire hd build i tried, then on the second, i skipped all the sync settings, still really laggy
On the m-deejay build I noticed that my cpu was at 100% constantly....
I've seen that RADIO version makes a difference. I am not sure what it is though as it isn't consistent and related probably to RIL version.
Right now I am back to 2.15.50.14 with MCCM 1.2b3 and it's been playing nice.

thnaks for the heads up, im gonna try this radio
After a night of testing, and a radio change, its still REALLY laggy, i really have no clue what is wrong, because using that radio which you are using, "2.15.50.14" it is pretty much unusable.
I never had this problem with the regular desire builds,
I'm on duttys V8 WM rom if that helps? Whould that affect it in anyway?
try with defragmenting your mem.card..
try with Restore Factory Data from SD & Storage menu (it will not erase your data actualy)
format your sd card with SLOW formatting, 32kb clusters
install & boot android
when on lock screen, dont touch the phone for 10 minutes
reboot
when on lock screen, wait 5 minutes, then unlock and do the wizard
after the wizard dont touch the phone for 10 minutes
reboot
when on lock screen, wait 5 minutes, then unlock and wait 10 minutes
reboot
when on lock screen, wait 5 minutes, then unlock, wait 10 minutes and then.. enjoy your fast android.
Yes, it takes time, but it works.

First of all I know screen freezing is a common problem that's not solved yet, but I really can't hold it any any any any more...
I got my HD2 just several days before(not t-mobile edition), now I'm using mattc 1.6b with 2.12 radio. Already replaced the original PPP with RMNET.
I don't know how about your situation, but my screen freezes about every 5 minutes, about 20 seconds a time, and if I turned my GPRS on(I'm not using 3G yet), it freezes almost EVERY 5 SECONDS... It's crazy
I can barely use my HD2 now, if there is no network connection, what could I do? I really don't know how to do, could somebody give me any advices?
It's a well known issue related to the G-Sensor. I can only recommend turning off screen rotation and trying other Android builds.
Edit: Here's a good thread to look at too, maybe one of these solutions might help you out. (link)
Thanks a lot, I'll try it.
try to boot the andoird as soon as you boot the WM it did help me or that issue
I was experiencing freezes with chunky droid, last night I changed to the latest vbn rom (full rom) (says he cooked in the power and performance tweaks) booted it calibrated g sensor, booted android no more screen freezes.. Using mattc 1.5c.. I didn't change my andoid rom..
Sent from my HTC HD2 Android
I am using the same rom. Infact the last few roms I tried I never experienced screen freeze - it works seamlesslessy perfect. It could be your SD card. Reformat it and reflash again
all the advice you need is in the thread for your build ...i promise

remove the setCPU app and disable screen rotatation if you don't use it, i have no screen freeze at all after that
Yea. The setcpu gave me a lot of freezes too...
ok screen freezes is a known issue, and we do not need another thread on it.

Phone freezes no matter what I try. Stumped
I have a question that seems not to be able to get answered where ever I post it. so please forgive me for posting here if this is not the correct place. I have been trying android from the beginning and I've tried everyones builds. from winmo to droid and different radios to find the right combination. The problem i keep running into is that my phone freezes up no matter what i do. I tried the letama .2 & .3. This problem even occurs in winmo even with the sd out. I may get a full day out of it with no problems then the problem returns. Right know i'm running MDJ Froyo revolution v.1.3 and winmo ozrom 5.10 wwe and radio 2.10.50.26. Also, wipe the sd clean every time i switch builds or upgrade. Haven't figured out how to do logs yet. still searching and reading to try and teach myself how to be more useful around the forums. Thanks and I appreciate all the hard work the DEVS put in. That's why i follow the rules except this time.

Obey the rules!
Naa, just kidding. But if your phone's freezing even in WinMo there's something really messed up. Did you try to make a task 29 and flash your ROM again? That might be helpful.. If not, turn your phone back to original standards (ROM, HSPL, Radio must be as given by the factory) and go to your retailor to use your guarantee if you still have.

I like you sense of humor. thank you for taking the time and commenting. there has been 30+ people that have viewed this and haven't even responded. But, some can ask like where is the download link and we all now where its at. always at the beginning of the thread,but they get all kind of replies. It just makes no sense to me when someone has a legit question they can't get much help. don't really understand that. Thought we were here to help each other.I don't believe that its an issue hardware issue. i believe its more software than anything. It comes and goes. My phone was going thru a period where it would reboot all by itself with no apparent reason. Then all of a sudden it stopped it and hasn't done that for 4 to 6 weeks.
really 97 views and no insight.
you tried the stock factory rom?? It might be hardware. You will be surprised a tiny drop of water inside your phone will slowly mess up your phone through a long period of time.
Are you on tmobile? I will try to look for a stock rom for you.
BTW, what do you mean by freezing? it hiccups or you have to do a battery pull.

btw, your title is a curious one, that is why you have many views and received little to no response. If they can't help you they won't post anything. But I will try my best to see whats going on.
if your suffering from the freezes in winmo and android then you I think that you need to forget about android for the time being and concentrate on getting a stable WM set up........
If you havent already done so then try a hard reset and see if that helps.......
try booting and running your phone with and without your sd card........
with and without your sim card........
if it still happens after the hard reset then you will need to reflash your WM rom, if you plan on using the phone mostly for android then I would opt for a basic rom like the energy reference series or one of duttys roms.....
there are many reasons why your phone might freeze and you need to spend time trying all situations to figure out what makes it freeze..........
if it still happens after the reset/reflash then we can only assume that it is a serious problem which may well require a warranty replacement.....
if your suffering from the freezes in winmo and android then you I think that you need to forget about android for the time being and concentrate on getting a stable WM set up........
I have tried all that you have suggested. The curious thing to me is that it seems to come and go. It first started with the energy rom and it's also happened with dutty's as well. if you guys know how to pull logs that devs need is possible you could give me a run down on how and then maybe i can find out if it is hardware. My phone has never been near water. i'm very careful about that. I'm using ozrom now. This is the 3rd HD2 i've had. the last one lost all touch response. I just have a feeling its software, but i just have a gut feeling on that. Thanks everyone though for your input i greatly appreciate it and keep it coming.
BTW, what do you mean by freezing? it hiccups or you have to do a battery pull.
I have to pull the battery. Then i may have to leave it out for a minute or two maybe longer then replace battery before it will load windows. it will just show the splash screen.
was this happening even when you were running the stock rom?
Have you tried to reformat your SD Card? I have two, and when I used my original card received with my HD2, TMOUSA, it would freeze. Since I reformatted and use new and old card, no problems for over a month.

YES

yes. I have two the 16 that came with it and an 8. it happens with both. I reformat every time i switch builds.
I see that your using radio 2.10 and that caused my HD2 to freeze a lot. change your radio to 2.12 or 2.14
I use the same Android build as you but with the elegancia gtx wm rom with radio 2.14 and after upgrading the radio the freezing (SOD) stopped.
I started using the radio 2.15.50 and have had no problems whatsoever. Also unchecking auto rotate and auto britghtness helps. Sometimes redownloading and installing your Android helps if you got a bad download the first time.
Update
now runnning enery extreme from 11/5 and mdj desire hd with his newest kernel smartass and the only time it freezes in during a call. usually anywhere from 5 - 15 minutes into the call. Anyone have any insight two a possible solution?
This is what I would do:
1. Task 29
2. Flash a slim WM ROM such as the one mentioned in my signature.
3. Flash a NEW RADIO...at least 2.12 or even higher.
3a. Install NOTHING. NOTHING AT ALL. Just answer and make calls. Period.
4. Test that build for two days. If I have freezups, then my phone is bad and I would flash the stock rom and radio and return it. If it does not freezup goto 5.
5. Completely reformat my SD card to Fat32 32kb (or 64kb if you think it affects stuttering in music).
6. Since you and I are both in the US, I recommend getting an Android that has a built in TMO MMS fix such as the new MDJ build (with link to MMS fix) or the fine MooMoo build or even Bluetopia.
7. Test the basic features in Android for two days minimum and see if I get freezeups (after disabling auto-rotate and wi-fi on the Android build as well as completely shutting off all radios in WM).
8. Be glad I got this far, and slowly reinstall my apps, testing each thoroughly for freezing.

Thanks for taking the time to post this i appreciate it. I have tried it all. It appears to be getting better. I have been using MDJ's kernels since he posted them with his desire hd build. I have always felt that it was software related and not hardware. It appears to me to be caused maybe by the data drops from ppp. Not sure though till i teach myself how to do that. thanks again though.
Turned out to be a hardware issue. Got my new replacement and it works flawless. Can't believe the fun I was missing. At least it was a great learning experience.

MDJ's builds work perfectly for me, 3g, WiFi, Navigation & Camera all work for me.
They all worked on Darkstone's too for me.
My advice would be stick with WinMo if you're not happy with what's on offer
Get mattc's 1.8 and hastarin 8.1. With Chucky ROMs this runs smooth like butter. And everything is working.
sounds like force close issues due to trying to restore data from other builds? or leftover data being picked up off the card causeing corupted files.
all the builds you mentioned are pretty reliable builds, that leads me to belive issues lie on your end.
if it was me?
id do a full format, not the quick format in windows. better yet, do it in gparted! a linux machine will do a much better/cleaner job.
Hi there! after googling a lot, and looking here and there around the forum's threads, i found no solution to this one....
I'm quite new at all this so i might not make myself clear enough.
I am using stock winmo HD2 Rom (the october 2010 ROM Update for EU) with 2.15 radio version.
So far have tried only Mdeejay's roms yet still i will try the rest to confirm the problem exists.
So on the first load of any of the version's i've tried (even after swapping kernels and trying different sizes of data.img file) android boots perfectly, runs amazingly smooth, fast, battery long lasting and so on (thanks to MDJ for all this), yet! i've seen many people have the same problem: After some random time (maximum of a few minutes) the phone reboots automatically thus taking you back to winmo.
It's not that i don't like winmo, it's just that i thought someone had found a solution to that.
So.... any clues?
mine is more of, turns off automatically. I thought the battery is dead (or the batt meter/notification is inaccurate) only to find out that it just turned off automatically.
have you tried checking the Q and A section rather than the Development thread???
2 solutions = Format sd card. if problem still persists than you need a custom winmo rom. I suggest elegancia. My setup in my signature runs without a hitch
iv never expierience this, i do get the coma bug, but iv heard a newer radio fixes that so im about to update mine

Sorry, was in a rather hurry and mistakenly posed it here, please admins could you move this?
I have the same problem.
At first the reboot was performed afeter a while, from 30 to 15min, and then it quickly began to reboot after a short time, around 5min. Now, the reboot is performing during the loading process of Android.
My winmo ROM is an Energy 23699 from 24th Nov, but the problem was present while I was in Energy ROM 21xxx from October one month ago.
My Radio is 2.07.50_27.2 flashed 5months ago, no issue with it.
My Android ROM is the llast Froyo with Sense from Darkstone (17th october).
I didn't formatted my SD Card because I wanted to know if there was some boot log somewhere in order to check the problem.

I am satisfyingly using android on my HD2 using a stock ROM.
I guess that the problem exists on using some of Android Kernels on some HD2s
I found my solution by using "evo carbon remix" currently using v.0.3.1 with Hastarin r8.2
I have not updated nor nothing, having a great battery life and all looking more or less the same as Mdeejay's rom.
I hope this works for you too!
@jsacp : Thank you for the advice, I will try later when I will 100% switch to android.
Well I think I have found the problem. My data.img was 256Mo and I have installed a lot of applications lately, maybe I ran over memory. I replaced the 256Mo data.img with the 1Go data.img which was present in the archive of my Android ROM, and Android didn't have reboot since then. But, of course, I lost all my setup, preferences and applications, I knew it before doing the jump, but glad to see Android back on my HD2
Hope it can help.
Did you notice if your phone feels hot at all? Last time I had a reboot I was downloading stuff with the phone plugged in and it got really hot and restarted. Was an older kernel tho and I think it happened when ppp connection got stuck.
Sent from my HTC Desire using XDA App
When I undervolt my phone too much, it starts randomly rebooting as well.
My guess is that mdeejay's undervolt is too much for your phone.
Try a ROM with hastarin's kernel, it will probably end the random reboots.
How to fix Android phone automatic rebooting problem
Recently my phone got into trouble, it kept restarting. I had to get out of the boot loop error. My phone was HTC Desire 1818 runs on Android Bravo. I was really frustrated because I had many valuable phone contacts in my phone. I searched everywhere on the, I couldn't find any solution at that time, so the only solution in front of me was to format my phone!. Oh.!.. Error fixed by formatting, but my all data on the phone including my valuable phone numbers lost. After 7 or 8 months my phone again got in to the same auto restarting trouble when I installed WhatsApp in my phone. It was really irritating me to encounter these sorts of wretched errors on Android. But at this time I found a good solution. This solution is available and applicable for all Android phones, and Tablets regardless of models and companies.
The solution is simple, Simply Switch on your Android device in 'Safe Mode'

Hey guys.. I love Android. I've ran so many different rom's and CM6 Nightly's n such on my Nexus One and I really love the phone. I love this HD2 also tho.
I've been using the HD2 with DarkStone FroYo for the last 10 Days or so. I must say I LOVE the HD2. It's a great phone, I love the screen and it's size, but hard buttons all being one piece of plastic was a bad move but thats about it.
Basically here's my issue. I have screen freezes that are a few seconds, or up to 10 allll day long. sometimes it will freeze and wont go into sleep mode for up to a minute (at least a few times a day) I lose my Data signal at least 10 times a day also. Sometimes it comes back, other times I need to Toggle Airplane on/off and my signal will come back.. Basically it's very smooth and awesome, then just craps. and this is extremely often and very random and it's starting to get very irritating. I wanna go back to my Nexus. I've also tried SkinnyEVO and had similar problems.. Are there any ROM's that are smoother and more stable, screen freezes and data drop-outs are really starting to irritate me knowing I wouldn't have these issues on my N1.
Should I wait for Nand to get going, should I try a few more ROM's. Is there fixes for these issues? Any info or suggestions would be great. I'd love to use this for a Daily phone, but in the current state it's a hard call.
Man Try MCCM 1.6 with updating kernel hastarin 8.5
it doesn't freeze at all.
everything work no bugs at all.
camera with zoom , face detection.
it is an awesome build
which radio u have and wim mobile u got ?
Darkstone has not updated his build for quite some time. Definitely try an updated build with latest kernels before giving up on the ole HD2. The touchscreen freeze has been eliminated with the newer kernels. I've been using the Motodroid build which has very good performance with the best working camera; no green tint, full 5 mp with working wide screen mode and shutter sound is selectable (which I have not found in any other build).
I don't know what MinMo build. I'll check, but I have the latest Kernel for the HD2. Kernel 2.15.50
I'll check what WinMo after work. Thanks for posts. I'll report back later
Do try a newer build, like the others said. I upgraded mine to hdone and replaced the kernels and i have yet to have my phone screen freeze. When i was using every other build with the old kernals, it froze all the time. Don't give up on your hd2 yet!
I think you have hit on 2 major issues the first screen freezes has been pretty much solved with the latest kernels with the g sensor fix. So try Hastarins 8.5 or mdeejays latest.
Second the data problems still exist but has been much improved with Letamas Ril Wrapper and other ppp tweaks ,see Letamas thread. if you try one of the newer roms they might have all above already in, so worth a try before going back to nexus.
I've been following Android on HD2 since August, and I've gone from all your problems and more to almost none (touch wood: my phone has begun to freeze today after three weeks of no problems - I'm hoping it's an installed app issue).
They are getting better and better and it's only battery life which remains an issue (for me).
Everyone's going to have different results depending on Radio/Location/Operator, but personally the MDeeJay Sense Revolutions (both types - Froyo and his other one), have worked very well for me, on Energy ROMS (currently the barebones one).
I can't promise Android on HD2 will always be flawless, but your two biggest gripes are certainly solvable on the right combination. (I hope!)
Change your SD card to a Class 6 and let us know.
Give up on the HD2, go back to the Nexus, send me your HD2
Scan my signature for my setup - I find it the best after changing at least 15 builds, 7 WinMo ROMs and 4 different radio combinations.
PS I am really stubborn guy, so that tells you that I've tried all possible combinations with above count of builds, roms, radios - and so far this one gives me what I want: HD2 with the Build that is smoothest and more stable than any Android phone I played around with so far... including nexus one
Thanks for all the information posted here guys. I appreciate it. I'll try mdeejay's latest and see how things go. (all of mdeejay's are Sense UI) I want stock Froyo
Another question. Can I copy everything from my Android Folder, to a New Android Folder for the new ROM I'm about to try, and have everything be exactly how it is now on DarkStone, or will that not work?

Titanium backup is your friend there. google for the wiki and read up on how to backup and restore.
Oh and if you don't like Sense, that's fine, just install whatever launcher you want, press the home button and it will ask you what launcher to use, tick the box for "use this by default" and sense won't come back to bug you. You can also remove the lockscreen slide by deleting the "HTCLockScreen.apk" via adb.
Just also to backup what others are saying, later builds like the one in my sig are far more reliable and useable, I get no data drops or any of the other problems you experience currently.
I know how titanium and all that works, thanks for trying to help though.
I just figured since everything is in the Android Folder, couldn't I copy it to another Android1 folder and boot to that build, and everything be there. but if not. It's ok. I'll just titanium backup everything instead.
I'm thinking about trying out BiffMod 1.2

You need to change you're SD card. I had gone through the same problem with A-Data class 4 sd card...but large waking times randomly spoiled the whole android experience....so much so that I gave up android...
But ever since I went back to replacement 16GB samsung SD card (which is ironically class 2) things have improved...and the phone wakes up instantly..
Also upgrade the kernel to hastarin v8.5.1 of ur build..it just solved all Data issues for me..maybe it will work for you too
I'm using the stock 16GB Class 2 Samsung that it came with. I have a 16GB Class 10 in my Nexus if we want to compare. but I'm not sure how large the SD class will really change things. Maybe a little.
I came to the HD2 from a Nexus.
I love my nexus... but wanted a larger screen.
Originally I had all the issues you commented... Id already sold my N1 so I really had to work on the HD2 working how I wanted it.
After flashing different roms, radio's, androids and kernels Ive finally landed where I am happy and in just the recent weeks with the tweaks the devs have done to their kernels my phone is rocketing and would never go back...
Only thing I do miss is the trackball and its colored notifications.
OP, you asked about overwriting your files, here's what I did...
I backed up my whole SD Card to my PC, so that I had my full working phone backed up just in case.
I then overwrite the contents of my old Android build with my new Android build, ignoring the data.img file.
Then re-booted, and Voila! EVERYTHING (apps, settings, wallpapers etc) came back, but my ROM was faster and smoother and upgraded.
This was switching from one ROM-maker to an entireley different one (both were Android 2.2 though).
If this had failed, I could have wiped my SD card, and made a choice between trying a fresh new Android, or using my SD Card back-up. If I'd had to go fresh, I'd know my Google Account would hold my contacts and purchased app settings. The AppBrain app is also useful in this regard.
Have fun!
im in a similar situation. i got me a secondhand nexus one, to try how android runs on a native device. i walked around with it for some days now, and i think im soon going back to my hd2, cause I CANT GET USED TO THE SMALL SCREEN ON THE NEXUS XD
really. not.
android on the hd2 runs almost as smooth as on the nexus one, i dont even cared in choosing the right build for my hd2, i just picked froyostone, and thats it xD
so yea, in the end, the only thing i really love on the nexus one is the awsome trackball, with its different colours :3 omg i want that on my hd2... ;(
i was having the freezing problem when i was using energy rom with the stock sd card when i flashed to the newest tmobile rom all of my freezing went away so if you have that problem try the newest tmobile rom it worked for me
