Antifreezing Tips

I have been using rom 3.1.2 now since it came out...along with k6.9 and 7.2.

ZERO FREEZES...a known reliable stable combo. (even with the complexity of my personal setup) The exceptions listed below represent the most common culprits...

Bad Blocks and System Cache...I can't prove it, but when I changed from 150 up to 180mb system cache, knowing that I had 6-8 bad blocks, I stopped getting freezes 100%. (a few months ago) I would like to think that the OS marks the BB as BAD and consumes more space if it is available. (to my knowledge, no one has proven this)

Boot Loops or Boot Freeze...make sure you have enough or MORE than you need for System Partition...eg 180m

Undervolting definitely can cause hot reboots...possibly even the stock voltage settings may be too low for some finicky CPUs.

Zram...I used to use Zram and it was very reliable...but somewhere along the way, it became unstable when combined with AUTO KILLING using apps like System Tuner Pro. I finally made the switch to a Swap partition and all has been stable since. With my setup I have 100% control of when apps get killed...BUT even with Swap, there is a certain low memory threshold when the system will become unstable and freeze. (500mb swap + 200mb real ram = 700mb at boot. I can't let it get below 250mb or it will freeze) and believe me...I did the homework and the testing.

SDcard...it goes without saying that a bad SDcard or a poorly formatted SDcard can cause major issues especially when using EXT3/4 partition. CWM stock formatting seems to be the most reliable.

Over/Under-Clocking CPU...yes, some CPUs cannot handle 96, 128mhz or even 245mhz especially under certain load conditions...including wake from standby. I Overclock mine to 1420mhz (whatever that actually is) and anything higher has potential instability for my CPU. NOTE: careful not to have more than one app controlling your CPU scaling. Lastly, I have been using Smartassv2 for quite some time with NO SLEEP profile. I get some of the lowest standby battery drain values.

OTHER...once in a while...sh*t happens....either an app freaks out, or a bad release version, or a random OS glitch etc etc. We should not be so surprised to have a freeze once in a blue moon. But regular freezes can usually be addressed and resolved.

Hi sounds good. But where i can download the 3.1.2 Rom? in the mirrors is the downloadlink deleted. plz help.
[HD2 Android NAND Development] ionbasa:
You cant download the 3.1.2 Rom. It doesn't exist on the download site anymore. Only way of getting it is by:

a) asking Dorimanx to re-post it

b) someone else might still have the .zip, but they need permission from Dorimanx to re-distribute it.
[HD2 Android NAND Development] sum8222:
hey, after changing to light rom, freeze problems not occur on my phone anymore! :)
[HD2 Android NAND Development] themadproducer:
Check your PM.
[HD2 Android NAND Development] maxking:
hello everyone how do I change the system cache 150 to 180?

I have to reinstall the new recovery?

I have the CWR_5_150_5m_EU_5.0.2.6

very thanks
[HD2 Android NAND Development] sisferas-sax:
yes you must reinstall it from the recovery menu (flash zip)

download the recovery http://www.bourseanalyse.fr/dorimanx/ open the flash.cfg and change system ya 150 with 180M
[HD2 Android NAND Development] somebully:
As smooth as this rom? I tried tytung hwa ics v2.2 but it was lagging and not smooth at all.. Slow response for instance setting an alarm..
[HD2 Android NAND Development] alho:
Or, if you like to install CLK (I prefer CLK) you can install this leo.img as the easiest way. but please unpack the zip and do it on your sd root card.... THANX :) I think, its a manual in the zip to know to work with it....
[HD2 Android NAND Development] maxking:
very thanks

need FRIST task29?
[HD2 Android NAND Development] sum8222:
hey dude, thanks! my phone now run smooth!
[HD2 Android NAND Development] alho:
I would recommend you to use task29 to get a very clean system.
[HD2 Android NAND Development] gomez.pl:
Im using 3.1.7.1 and I noticed one fail:

When I want to wake up the phone Im pressing the red button and then I want unlock the screen but it dont react at all.

I need to switch off the screen wait few secounds and after that I can press the green button and unlock the screen

the screen stop to react when Im using keyboard

Its happening from 3 days....

Can someone confirm that
[HD2 Android NAND Development] fahd_freak:
Yup... Same thing happening to me... I think something broke the fix for screen turn on delay fix auo panels in the latest kernel..
[HD2 Android NAND Development] gomez.pl:
but Im using kernel 6.8 not the lastest one (7.2)

and what can cause that ? Its very arduous....
[HD2 Android NAND Development] hoost_pt:
I'm using 3.1.9 ROM with 7.2 Kernel since release day without any issue at all, 0 freeze, 0 reboot, no lag, battery with moderate use last for 24h... The best so far...
[HD2 Android NAND Development] hoost_pt:
Try update to latest ROM + Kernel and don't use clock speeds below 245mhz

Fyi: I use SetCPU with SmartAssv2 governor in all profiles
[HD2 Android NAND Development] gomez.pl:
So I will wait for new ROM, hope its going soon :)
[HD2 Android NAND Development] moti1elash:
Understand. Try to wipe dalvik cache.
[HD2 Android NAND Development] hoost_pt:
Did you already tried the 3.1.9 ROM and 7.2 Kernel?
[HD2 Android NAND Development] piet3r:
Hi guys.

A few days ago I have installed the new ICS rom with sd-ext and zram partition.

After I installed, I turned on my phone, but the phone does not recognize the sd-ext partition. I don't know if zram works, beceause I don't have enough space to install apps. I reinstalled the rom and kennel a few times, but that did not work.

Any tips?

Thank you. :)
[HD2 Android NAND Development] gomez.pl:
I have changed the Rom and kernel for ver 7.2 but still the same :P

I made wipe cache, dalvik...

whats goin on ?
[HD2 Android NAND Development] jack2502:
Black screen again -.-

I posted this problem before month´s ago, and now i´ve got it again. After doing a full wipe because i had tested ICS, i updated to latest DM rom. After having installed and backed up everything, I can use the phone as always, until it sleeps a longer time. Then, when I try to wake it up, only black screen and button lights appear. Only way out is to remove battery, but on next wakeup it happens again. I tried different Kernels, reflashing, wipe dalvik and cache partition, but nothing helped. Hope you guys know a way to fix this.
[HD2 Android NAND Development] Hinnne:
try not using 96mhz and ...

start with 245mhz as min.

perhaps try another gov.

do not uv.

this is the only thing i can think about which can cause such behaviour.
[HD2 Android NAND Development] jack2502:
I tried with 245/998 or even 998/998, but it still happens. I also changed the governor, nothing changed, and i´m not undervolting. Can´t imagine what could cause the problem:(
[HD2 Android NAND Development] hoost_pt:
Did you try disable lockscreen to see if the problem persists?

I use WidgetLocker Lockscreen and don't have any problem
[HD2 Android NAND Development] jack2502:
Thats a possibility i didn´t think of, I´ll try it the next time i get the black screen, the last few times it woke up as normal:confused:
[HD2 Android NAND Development] gomez.pl:
Screen is freezing ....

I tried new kernel, new ROM, other ROM but still the same, can someone help with this issue ?? I need phone for work...

Edit:

I think its hardware issue.

Im just testing the WM 6.5 ROM and its the same problem with screen....
[HD2 Android NAND Development] jack2502:
Ok, it happened again, also after changing to Widgetlocker. With the only change that with widgetlocker the background appears on wakeup, but without locker. Then i´m able to put it back in sleep with power button, but after wakeup again only background appears. Any other ideas?
[HD2 Android NAND Development] themadproducer:
A Shot in the Dark for yah (hey I like the title)

Try disabling Auto Brightness and test.
[HD2 Android NAND Development] jack2502:
Interesting idea, I´ll try it:D
[HD2 Android NAND Development] maddoc1007:
http://www.androidpolice.com/2012/0...e-and-now-parts-of-it-are-being-added-to-cm9/

hi dori have you seen this linaro seems it makes cm9 twice as fast you should look at it maybe will help with this and cm9
[HD2 Android NAND Development] themadproducer:
The video of the benchmark interview is impressive!
[HD2 Android NAND Development] x3dnd3x:
I have this problem too sometimes but it didn't really affect me much. If you just leave it as it is for a while, the problem would go away and your lockscreen would appear again. Of course to most it would be irritating.

Do you so happen to be using GoLocker? I used GoLocker and once in a blue moon I would have this issue.
[HD2 Android NAND Development] maddoc1007:
lots more info at www.linaro.org

they have a working ics for panda board
[HD2 Android NAND Development] piet3r:
Hi guys,

I did a fresh installation (task29, mag, adrec (250mb), partionSD, etc)

When Installing the aroma installers says: SD-ext: -1mb.

The SD-ext is still not working. Do you know what is wrong?
[HD2 Android NAND Development] jack2502:
I tried disabling auto brightness, but it didnt help. And i'm using the build-in locker. Nothing helped, so i did a clean install again. This time i didnt restore or install anything, and until now i only had one freeze. Now i'm beginning to restore everything piece for piece, lets see what caused the problem;)

Edit: Ok no restoring, now I get freezes instead of blackscreen-wakeups :( Seems like i´m doing something wrong or my hd2 is broken-.- Or maybe it´s the SD card..?

Edit 2: Ok thats it, I´ll try another rom and see if problem still appears. I really like this rom, but these blackscreens and freezes are really annoying:( But it seems like i´m almost the only one, so me or my device are stupid:D
[HD2 Android NAND Development] themadproducer:
I would like to see you resolve this jack...I am rootin for yah! ;)

Do you use ODEX option or Zram? Try without either of these two.

Any chance you are running low on ram when attempting to come out of standby?

Have you temporarily tried running a winmo rom to rule out HARDWARE being the issue.

Finally...I read somewhere one time, a similar problem resolved by not only disabling auto brightness, but Wifi Sleep policy set to NEVER....and reboot. Yah never know with these quirks. My wifi happens to be set for NEVER and I don't use autoBr. either. You can't lose to try.
[HD2 Android NAND Development] guma55:
i have install new rom and 7,2 kernel and now i stuck on boot screen i have 170/5 partition
[HD2 Android NAND Development] maddoc1007:
try 170/10 everytime i used ###/5 i had problems since changing cache to 150/10 iv had no problems

hope it helps think 5 cache is too small
[HD2 Android NAND Development] guma55:
still the same i stuck on boot animation
[HD2 Android NAND Development] nqkoidrug:
Do you wiped cache, dalvik and fix per. ? After flashing with 7.2 ?
[HD2 Android NAND Development] maddoc1007:
linaro gerrit

hi dori here is gerrit for linaro if u want to take a look

http://review.cyanogenmod.com/#/c/17380/
[HD2 Android NAND Development] jack2502:
I used no ODEX, but Zram;) Low ram cant be, had nothing running in background. I had both sleep policy set to never and disabled auto-brightness. I ran no WinMo rom, but now I´ve changed to Hyperdroid, and everything runs fine. Fast, stable, no black-screens or freeezes. So it´s no hardware issue (what i´m really happy about:D), but maybe i screwed something up with the Zram/swap partition... don´t know;) But I did so many fresh-installs that i dont think so.. For now I´ll stick with hyperdroid, maybe I´ll be back and try Dorimanx rom in a while. But thanks for the help guys, and keep the great work up;)
[HD2 Android NAND Development] imagin112:
Hi all :)

Rom is great, but I have one q.

I have problem with my ears, how to make more louder this rom?
[HD2 Android NAND Development] Hinnne:
Try app volume+ play store or search in xda

If you get buzz sound after using this app. reboot ROM.

I also changed handset in system/etc/init.d 10mic_level echo 0 from 700 to 800.

After reboot buzz sound bug was gone.

No idea if reboot is enough or if changing echo 0 is also needed to solve buzz sound if activating volume+.

But now all good and loud.
[HD2 Android NAND Development] imagin112:
What about sony xloud system? Do you test it on this rom?

Wysyłane z mojego HTC Sensation XL with Beats Audio X315e za pomocą Tapatalk 2
[HD2 Android NAND Development] Hinnne:
I do not think it will work on our phone.

dsp manager is also not as good as volume+

So deinstall dsp and use volume+

No idea why sometimes after playing music .buzz sound is here again then it is gone.

Perhaps dorimanx can look into this and solve this little bug.

But volume+ works great.
[HD2 Android NAND Development] themadproducer:
Ok Cool. Your back in business.

I have done an insane amount of Zram testing over the last 6 months and I no longer use it because it is ...well...unstable under CERTAIN circumstances. One of my XDA colleagues went and gave the latest rom/kernel a shot with Zram instead of Swap and immediately ran into F/Cs and the likes. You really should try the rom without Zram when you get a chance. (Unless I miss-read and you have already)
[HD2 Android NAND Development] hoost_pt:
I disable Zram a couple of Weeks ago using only use swap and it seems that the general behavior of the phone improved. I don't remember when I had the last F/C or random reboot :D

Everything running fast and smooth...
[HD2 Android NAND Development] JoonatanO:
Really stable on the latest version here. I was getting really sick of NexusHD2-Gingerbread getting hot reboots multiple times per day. It would randomly reboot during music playback, recharching, or just for kicks.

With this ROM I haven't gotten a single hot-reboot to date, it runs cooler than the previous ROM on stock clock speeds even when I overclock it.

Thanks Dorimanx; your ROM makes my HD2 feel like a brand new device. :D
[HD2 Android NAND Development] jack2502:
I´ll definitely try it, but not now;) If i get tired of hyperdroid, and there is no fast and stable ICS rom, I´ll come back here and try my luck;) Was a great rom until i updated and it stopped working:) But as said, Hyperdroid is cool, too. And I think its a bit faster;)
[HD2 Android NAND Development] dbsportsbrit:
I am looking for the the ringtone folder so i can add some of my own ringtones to it i found the notifications folder but i cannot find the ringtone folder does anyone have any suggestions how to add my own ringtones. thanks in advance
[HD2 Android NAND Development] x3dnd3x:
You must convert it to .ogg format to view it from the ringtone selection if I'm not wrong.
[HD2 Android NAND Development] dbsportsbrit:
i know in some roms you can use music as ringtones ok thanks
[HD2 Android NAND Development] maddoc1007:
u can find ringtones in:-

system/media/audio/ringtones u need a file explorer that allows u to look at system files
[HD2 Android NAND Development] dbsportsbrit:
My data signal keeps dropping with latest dorimax kernal I am tmous magldr
[HD2 Android NAND Development] MystaMagoo:
Just make a new folder on your sd card and call it ringtones.

Place your mp3's in there and then you can use as ringtones :)

Also you can do the same for 'notifications' and 1 other but can't remember the name?
[HD2 Android NAND Development] Looki75:
alarms
[HD2 Android NAND Development] MystaMagoo:
:)

that's the one
[HD2 Android NAND Development] trmacdonal:
You can put your "ringtones", "alarms", and "notifications" folders inside a folder called "media" on the root of your SD. This keeps it a little neater.
[HD2 Android NAND Development] yugoport:
Already searched but it's not easy to do it from the phone, anyone having fc with market?

Sorry if this has been answered.
[HD2 Android NAND Development] miguelidanez:
I also have problems booting after updating first time. I download again and all ok. Several error, but tried to close all, remove battery, reboot and OK.

It seems more faster and stable. I will check how is drain battery, because the last rom took less a day to drain with little use.

New music apk (version 3.0) works only sometimes for me (is it a beta?). However looks good.

I decided to use go launcher ex, and Equalizer, so I deleted .apk with root explorer.
[HD2 Android NAND Development] miguelidanez:
For "the_mouse": I tried Go Launcher EX with some previous versions and all worked ok, without graphics glitches.

Have you upated it to last version? It updates me just today, after installing this rom to version 2.39.
[HD2 Android NAND Development] virtuweb:
Bluetooth Audio Controls

I'm thinking about switch over to this ROM; however, I wanted to get some quick feedback as to if anyone has had issues using their in car controls to skip back and forth, pause, and play audio tracks. Any input would be greatly appreciated. Thanks:D

P.S. Ignore the signature is very old... LOL
[HD2 Android NAND Development] dorimanx:
About Cache,

We overload the SD with SWAP + EXT apps + files on FAT partition.

Then we expect that card will hold 2048 readahead cache... well it's too much to ask.

I made lots of checks, and there is difference from 4KB to 64BK, after that, no difference in read /write speed, only choke on buffers and IO wait time...

So Look like this is the best set...

Please use this, for some time... then update to 2048 in 99script (look for 64)

try to use, then you see no difference, only more LAG...

About the OC, yes i have configured ROM to use PERFORMANCE governor, in BOOT time, to faster the load,

And OC to safe 1.15Mhz,

Then when done load,

CPU will jump to ON DEMAND + tweak to power the Mhz up to max if needed when cpu need is over 40% to speed up the wake up and daily use.

But if you have SETCPU or any other app that tweak CPU then it's set what you have configured after app is loaded to RAM.
[HD2 Android NAND Development] dorimanx:
Actually i am using the same SET about the task killer,

It's very good combination!

Tuner is killing apps on screen off and advanced task killer, close unneeded apps every 30 minutes, they start in deep sleep...

So no LAG :)

The lock screen is cool, i like the style of unlock..

I am using GOTO lock (paid) but this lock look nice, i have tied it also..

No problem to integrate... i can also disable the internal lock by default!
[HD2 Android NAND Development] dorimanx:
New add-on :)

Please read the change log :)
[HD2 Android NAND Development] dorimanx:
NICE!!!!

Will be integrated to new ROM!

for now just install if you like :)
[HD2 Android NAND Development] dorimanx:
Can you tell me what kind?

I have updated to latest Graphics driver, but looks like some apps not supporting it.

But old driver cause instability, can use it any more :(

And also it's make lots of graphics bugs...
[HD2 Android NAND Development] dorimanx:
This hopefully will be fixed some day in nightly update,

Nothing i can do... sorry,

Use the touch 5 dots lock... much better. just don't show the combination to others :)
[HD2 Android NAND Development] michie:
Hey Dorimanx,

It is and stays your rom but isn't it better to create 1 clean CM7 rom with your tweaks but without additional integrated apps or themes ?

You can add your apps and themes to your download page in a second section and let the users decide what they want to install additionally.

This will make your ROM more appealing to other users on the HD2 forums as well.

Just a proposal!
[HD2 Android NAND Development] brolynchhung:
When recording video, audio seems to be low.
[HD2 Android NAND Development] ORiZorrie:
I would say allmost right after install. However the 3g connection drop was only noticed since yesterday.

Anyway i did a task29 and clean 2.7.1 install. Running smoother now already. Will report back when i have tested it more.

Thanks for ROM dorimax. Great job mate.
[HD2 Android NAND Development] dorimanx:
for now, its as is.

when I will be bored, I will think about it.

I have the best users here already,

and they know how to make the best ROM for them.

all tools in mirror.

Sent from my Dorimanx Rom on HTC HD2
[HD2 Android NAND Development] dorimanx:
did you covered the mic by mistake? :D

I will check, thanks.

Sent from my Dorimanx Rom on HTC HD2
[HD2 Android NAND Development] the_mouse:
What kind of graphics glitches?

on the home screen for example the icon dock at the bottom just turns into a white blur

when the desktop working area is slid to next screen the icon dock goes white

opening and closing the app draw leaves some artifacts behind on the screen
[HD2 Android NAND Development] miguelidanez:
DO you use advanced task killer and manager toguether? I also use Tuner Pro (for Dorinmax recomendation), and I have download Advanced Task Killer, but Advanced Task Mangager seems to be a similar program...
[HD2 Android NAND Development] brolynchhung:
Okay maybe I'm just tripping. With headphones on, it seems loud. Or maybe I just didn't have my speakers on loud enough.

Hey Dorimanx is there any way you can enable auto focus on video recording? I remember earlier Android builds had auto focus when recording.
[HD2 Android NAND Development] feanor91:
Hi Dorimanx

Updated 2.7.1 this morning (late on work by your fault...:))

Somewhere in the thread, you spoke about a mail app to remove that could cause some battery drain. Of what app did you talk about? I did'nt manage to find anyone mail.apk or somthinh like that ine app folder.

By now, I made an application (on pc) that wil be able to analyse the currentwidget.log. If someone is intereted in...Don't know if it will be of great help, but will see.

Another thing. Besides the use of taskkiller, I can see, that even if I killed a task, some relaunch very shortly (map for exemple). Is there an app or a tool that could block the relaunch of an app?
[HD2 Android NAND Development] michie:
Battery drain is reduced by 50% since 2.7.0, my battery now lasts +2days average use!!! :D

Great job mate, keep up the good work!
[HD2 Android NAND Development] feanor91:
and for me unplug at 6h am 1% at 22pm, no use of video and so on, only a few sms and look at screen from time to time.

Is someone able to explain, because I'm unable to understand something. This battery stuff drive me mad.

I applied all informations found here and there, use juice defender to block data (which is a huge bettery killer), but from time to time as phone is waiting, I have little drop, in battery percentage and I did not know which app made this
[HD2 Android NAND Development] Howell:
Try to clear Market cache ;)
[HD2 Android NAND Development] yugoport:
Thanks mate, already did,and Google services framework too..

Let me add that I'm using light version, odexed and 192 dpi, in system/app ,the vending.apk is the only app that has not an odex file, could this be the culprit?

Thanks
[HD2 Android NAND Development] x3dnd3x:
May I know whether its possible to edit the incoming and outgoing call thing? I recently purchased Ultimate Call Screen and it would preview the stock caller then UCS when I have a call.

Can I uninstall the stock caller so that it would directly show UCS? If yes, how?
[HD2 Android NAND Development] maddoc1007:
maybe its because u have dpi set at 192 i think u need hacked market?

partition size

Hallo.Maby I'm blind but I cant't find what partition size I must use.I want rom without swap:o
[HD2 Android NAND Development] Santiago94:
Anyone watching this? might be better to build a ROM on the LINARO AOKP instead as it is now. Although I see something recently that Dorimanx not seem the new version, bored? Link to the benchmark: http://www.youtube.com/watch?feature=player_embedded&v=mrQRYmYip6Q
[HD2 Android NAND Development] Hinnne:
150 is enough without odes option.

With you need 170

I recommend 180 to have no problems. And so bad blocks are also no big problem

---------- Post added at 10:53 AM ---------- Previous post was at 10:46 AM ----------

Cm9 will soon use linaro as base. I think aokp will also. So soon new power.
