You'll find the kernel 2.2.9 mentioned a few times in the first part of the OP (original post) page 1. It is not actually inluded in the ROM 2.2.2 download, but if you look closely to the

ROM

changelog, kernel 2.2.2 is (same as ROM).

If you scroll a little way down to Leedroid Custom Kernels and you'll find a FTP link and end up here;

http://leedroid.ftp.rshost.eu/DHD-Kernels/LeeDrOiD_Ace_V2.2.9_KERNEL.zip

You can also copy it direct to your dropbox from Lee's a little further down from that.

https://www.dropbox.com/s/nt7ddio6afj9ler/Addons

Lee has tinkered with the volume through his differing kernel builds, you might have to work through the various changelogs to see when it had been increased / decreased. Mine is still loud enough,.........but maybe I'm just used to it now :) The lastest build also has malware various patches, fix youtube bug etc

The index of his various builds is somewhere in his website;

http://leedroid.com/ (but seems to be down right at this instant :eek:)

Edit: Just flash it same as the ROM, place on sdcard and flash after boot into cwm recovery. It may take a little time to 'bed' (settle in) and also a reboot or two. There is info on the I/O patch and been discussed a few times also in the past couple of days. It is mentioned on OP page 1 and a small mention of a very small risk of potential data loss. It is supposed to increase performance. If you decide to use it (Lee has stated he is), flash same as the rest and immediately after the kernel before reboot.

Didn't make much of difference for me. Tried from 128 up to 4096. Put it back to the ROM's default of 128. Running a 16GB class 4.

Like I said it works for some SD cards but for some reason not all mine has doubled in write speed and got a more accurate 20.5 read speed

That's strange my friend.

My auto brightness doesn't work anymore after flashing this 2.2.2 ROM with 2.2.8 kernel. My proximity sensor works well though.

I noticed there is something (a .zip file) which can fix auto brightness but I just don't know how to fix it. Through CWM or using the Radio flashing method?

Just wonder how accurate is your feelings...:D
[Desire HD Android Development] UpInTheAir:
Cheers mate, :)

Did fairly thorough testing and found that some reults can vary quite a lot, but the overall mean has definately increased, particularly using 3072

In my case with a cl6 sdcard, now at 5.5-7.3 write & 50-178 read.

Excellent, thanks to brainmaster too.

oh, lee (and others) here some interesting sd card performance tweak:

http://www.androidpolice.com/2011/0...-200-with-a-simple-tweak-hands-on-benchmarks/

and yes, it really works ;) i have it running.
[Desire HD Android Development] UpInTheAir:
Cheers a user,

Leith51 was first off the mark a couple pages back. :-)
[Desire HD Android Development] a user:
oh. :O
[Desire HD Android Development] cgorki:
Hi Leith51 hi a user,

which values have you guys tested and flashed?
[Desire HD Android Development] a user:
i didn't tested much different values. the difference should be minor. i'm using 2048. in general it should be as faster your sd card is the higher the read ahead buffer should be. but 2048 should give you good performance in any case.
[Desire HD Android Development] UpInTheAir:
As Leith suggested/implied, the level of performance increase may be due to differing sdcards and class. Some may have huge gains, while others negligible. Obviously had a huge effect on mine at both 3072 & 4096 :)
[Desire HD Android Development] leith51:
i found the 3072 the best one for my card the 4096 seemed to drop lower after 5 tests one after the other

the 3072 was more stable and the varying was less but still doubled the speed played a few games and found them more responsive

its really a case of trial and error i would suggest test each one 5 times and take note of each result and stick with the one that your sd card is more stable with
[Desire HD Android Development] a user:
of course this is the case. the better (faster) the sd card already is the greater the benefit of a bigger buffer is. at the same time, if the buffer gets to big you start losing performance due to useless read ahead.
[Desire HD Android Development] CitizenLee:
I'm using a Transcend 8GB, so will give it a try on my lunch break. I always did think it seemed a bit slow for a Class 6.
[Desire HD Android Development] UpInTheAir:
I can see what your saying :cool: Good insight.

But,........... if there was a performance loss, probably not any noticeable 'real life' loss. Here we can at least see a noticeable 'real life' performance increase. Open gallery, and bam !!! All 200 pics are loaded almost instantaneously :)
[Desire HD Android Development] a user:
this sounds great. i haven't seen any reallife performance gain up to now. i see the sd card benchmark shows improvements, quite big ones, but in practice i didn't observed any difference.

have a 32GB class 4 card. arround 6 or 7 GB free.

edit: i just tried some other buffer sizes. am now on 4096 after trying 3072.
[Desire HD Android Development] CitizenLee:
It's not lunch time yet but I got bored....

As I mentioned before, using a Transcend 8GB Class 6.

I tried all the options (changed values with Root Explorer between each test) and see a little bit of an increase in speeds over default. I think I'll flash the 4094KB file.

[Desire HD Android Development] UpInTheAir:
CitizenLee,

Are you using gscript to test and ammend your value of the script script each time?

Those flashable zips don't work, and will need some slight changes to the script to stick on boot.

My slightly ammended script in a post above did the trick, and checked value after boot, all good. I just used RootExplorer to paste it in init.d.

If you don't know, don't forget to mount r/o and save changed permissions, as well as removing the .sh.
[Desire HD Android Development] CitizenLee:
I've only done the testing so far, hadn't got round to making it stick yet.

Thanks for the tip though, that will save me some head scratching! ;)
[Desire HD Android Development] tvetkalle:
The Flashable zips working fine for me...but only if i fix permission in clockwork mod before i flash the zip. otherwise it doesnt stick on boot.
[Desire HD Android Development] UpInTheAir:
Cheers, will give it a try (although managed to get it to work by other means)..... nothing else to do ;)

Edit: Yep, no issues with your way as well. Probably much easier and faster if your not to sure about creating and applying the script manually.

Patiently waiting for Lee's surprise :cool:
[Desire HD Android Development] turkish-soldier:
yeah,,you are right

it all comes from noobnes:\...yeah you are right...we learn it...but it needs time...i have read those pages but i didn't get it...so i asked it this way...well now i know it...thank you all :P
[Desire HD Android Development] UpInTheAir:
Yep, no problem, I'm relatively new to android too & seem to learn something new everyday. A lot is by trial and error (thankfully not too much error :eek:), but before I do anything, I try and read up all I can on XDA and shhhhhhhhhhh other sites, to educate all I can first. Some things go straight over my head too.

Keep at it, but don't panic. ;)
[Desire HD Android Development] andreasy:
Have you realized that SD tools will give you a + - 1.5 at each run, regardless if you change the cache size? How can you trust that the new gain or loss is due to the cache change and not just a random variation?

Personally I don't trust it and I'm leaving the default 128.
[Desire HD Android Development] UpInTheAir:
You're doing the smart thing ;), particularly since your seeing no noticeable increase in read?

Mine has increased 2.5x (50) -> 9x (178) since changing to 3072. Yes quite a large variation, but at a min many times that of the original value.

'Real' speed increase is evidenced by a huge increase in loading speed when opening gallery and having the thumbnails of my 200 odd pics displayed. :) So convinced to leave it at that ftm.

Others have seen little change :(

I upgraded to the 2.2.9 kernel last week, but ended up doing a restore as the battery life seemed awful, drained away within about 8 hours, and I barely used the phone as I was working on my car all day.

Anyone else find this?
[Desire HD Android Development] CitizenLee:
I tried v2.2.9 for a few days but went back to v2.2.8 as well. Battery drain wasn't as bad as yours but it was more noticeable than on previous releases.
[Desire HD Android Development] a user:
i have not observed any difference regarding battery drain between 2.2.8 and 2.2.9.

considering the changes i doubt it is due to the kernel. maybe it was a coincidence when you had the newer kernel. i suggest to try that one again and see if it repeats.
[Desire HD Android Development] CitizenLee:
I was also having video issues I'd never experienced before with v2.2.9. No problems since going back to v2.2.8.

Coincidence? Maybe... but v2.2.8 works perfectly so I'll stick with until Lee's next release.
[Desire HD Android Development] 2-die-4:
Okay, cheers I'll order a new one that can "hold" the charge
[Desire HD Android Development] cgorki:
I changed the values manually via root explorer , later I also flashed the patch.

[Desire HD Android Development] tolis626:
Hey guys,I applied the SD patch(or whatever it is) and I found it works better with 3072 for me.A test with SD tools gave me 14,5Mb/s write and 140Mb/s read! :eek:

I have a 16Gb class 10,so not so big a surprise,it's just that it was around 5-6 before. :)

However,I now have a problem.I ran three consecutive tests with SDTools.As you probably already know,during the test it creates a 190mb large file on the SD,which it deletes.Mine,however,didn't delete the files completely,and something got corrupted.It kept saying my SD is mounted as read-only,but it was easily fixed with a check in windows.But now,when I try to run a test with SDTools,it won't start testing.It stays there saying "Writing..." but the gauges won't move and it doesn't test.I tried uninstalling and reinstalling from market and I tried deleting the SDTools folder from my SD.Nothing.

Any ideas?

Also,Antutu still gives me pretty low scores for SD w/r.Any ideas for that?

Thanks! :)

[Desire HD Android Development] UpInTheAir:
Did you find an answer to that issue?

A workaround could be using Titanium to move in batch mode and select some of the apps to move to phone internal memory.

This would easily move apps from the ext3 (a2sd+) to the internal and reclaim some of that 'wasted' memory.

You might have to reboot after. I haven't tried yet, as current use 1gb ext3.

Edit: Not sure if a2sd+ script will (should) try and move them back to ext3 during reboot? If you still want to use the ext3 partition, maybe you could just reboot into CWM recovery and increase the ext3 partition to 1gb after moving to internal.

(THIS USUALLY OCCURS WHEN the messages are about to be wiped).

after this my DHD's battery drains much faster, i've repeatedly tried to close the app but even then after sometime watchdog alerts me. and the battery drain is back.

Hi, i would like to flash this fabulous rom on my desire hd. I have some quick questions, i already have root, s off, radio s off and clkwork.

So i would like to install the rom, the radio, the notification power widget, the a2sd patch and the kernel.... How can I do it? I make a full wipe from clkwork, then install rom, without rebooting continue installing power not. widget, a2sd and kernel, is that correct? After i install the radio, or is better before on the other rom i have? For A2sd which is the recommended maximum size i can make, i have a 16gb card. Tahnkyou!
[Desire HD Android Development] SupremeBeaver:
No i believe you must reboot at least once after flashing the rom. Then i would flash the kernel followed by the power widget. Im not too sure about a2sd because i dont use that, maybe someone else could chip in here.

As for radio, it doesnt matter when you flash it, before or after is fine.
[Desire HD Android Development] a user:
skip the a2sd patch. it has nor real benefit.
[Desire HD Android Development] winwintoto1234:
SupremeBeaver is right.

You should reboot at least once after flashing the new ROM. If you flash other things immediately after ROM, your phone MAY not be able to boot after that.

Tell from my own experience...

Make a full backup in CWM recovery & copy sdcard to pc !!

512kb and up, I use 1 gb, 0 swap

Full wipe if comming from another ROM or experince problems

Place ROM, latest kernel 2.2.9, i/o patch, a2sd+ zips on sdcard

For safety, enable USB debugging !! (although flashing kernel 2.2.9 will take care of that anyway.

CWM Recovery; flash ROM, a2sd+ patch, kerenel 2.2.9, i/o patch in that order

don't use system/app. apps in this directory may have special permissions. this is for so called system apps.

[Desire HD Android Development] SupremeBeaver:
Hey guys decided to use the UOT kitchen for the first time in my life today and im facing some big problems. This is what i did.

I selected a battery mod, uploaded my framework, then cooked it. I then replaced some pngs within the drawable-hdpi-v4 folder. I just wanted to use a few different icons in the statusbar. I then decided to push the framework-res.apk directly to the phone using adb rather than flashing it and now i get MANY force closes when the phone starts up. However i can see the mod was applied because i can see the new battery mod. So what could have gone wrong here?

Is it because i decided to push the framework-res.apk through adb rather than flash through recovery?

Also on the file upload page there are some options which i don't quite know what to do with. Look here:

http://img96.imageshack.us/img96/5535/unledr.jpg

I just left that the way it was. Could this have been the cause?
[Desire HD Android Development] a user:
1. you should replace the pics BEFORE cooking with uot (because of signing etc.)

2. try deleting dalvik cache. this you usually should do anyway after replacing/flashing a new framework, no matter if you push it through adb or flash it from recovery.
[Desire HD Android Development] SupremeBeaver:
Thanks for the response. So the image i posted.. are the settings fine? Im still using clockwork 2.5.3 so maybe i should have ticked the second option?
