[Q] kernels

hi, i'm about to flash leedroid v 2 on my desire hd, but i was wondering what the kernels in his site for? do i really need to flash them? and how?

This is what a Kernel does:
http://en.wikipedia.org/wiki/Kernel_(computing)
Or, a short explanation: It's the interface between your Hard- and Software.
The faster and the more optimized it is, the faster, smoother and energy efficient your DHD runs.
If you're on Leedroids ROM you already have one of the best Kernels around.
In this case it only makes sense to flash another Kernel if you want to overclock your device. (And no, I won't describe overclocking, too. If you've clicked the link above, you're already on wikipedia to look that up, too ;-) ).

i think leedroids rom includes his latest kernel anyway, the flashable one is for people not using his roms

Every ROM comes with a kernel. Leedroid 2.0 came with a kernel. Then later Lee added some modifications to his kernel and a new kernel 2.0.1 was made available and so forth until 2.0.4. Since changes were somewhat minor he did not introduce a new ROM version. But this means different people may be using the same LeeDroid ROM each with different kernels and different experiences. For example the latest recommended kernel seems to be 2.0.3 as 2.0.4 has more battery drain.

Same problems with several Roms (Battery, shutdown, radio)

I try now since 2 moths running Android on the Kaiser with full performance.
I fixed several problems, but there are still some which frustrates my really!
1. The Battery lifetime is very short. The battery indicator in the homescreen reacts very slow, so it could be possible that I leave my home in the morning and the indicator shows a full battery. During the morning the Kaiser shuts down because the battery is empty. If I try tio charge it and connect it to the charging unit the charging process runs. When I disconnect it several hour (approx. 5 hour) later, on the display appears the massage that the battery is still empty. The problem is nearly the same with different Roms or Different Kernel. I never had this problem with Win Mobile.
2. I have a bad Radio performance. I tried several Radio Roms, but I couldn't fix it. Are there any possible values I have to change tio get a bvetter performance? When I have my HD2 next to the Kaiser it has each time a good Radio and the Kaiser has no Radio. Is it normal that the Kaiser has a worse Radio tehn the HD2?
I'm running at the moment the .25. Kernel with the update. But I had nearly the same problems with the .32. Kernel. Just the radio performance is a little bit better with the 25. KErnel then with the 32. Kernel.
I thik the problem could be at the kernel, because the problems are similar with each Radio Rom. Can anybody provide me a source with I kernel I can install which he knows thet the kernel will work very well?
I will have a stable Kaiser with Android and full performance. Thanks in advance for the help!

Can somebody help me please?

Change the kernel to possible an older one. And mind to use Kaiser specific kernel. Plus, What build you are using ? maybe possibly the instability of the build

Thank you very much for the feedback!
I tried the .32 kernel and the .25 kernel With the .25 kernel, I had a better performance the the .32, but not the full performance! Can you please help me with a link with a kaiser-specific kernel? Maybe I had the wrong one, but 'm not sure which one is the right.
I've tested several builds. The most stable ones were:
- not so super RLS 18 and
- My Modified Fresh Froyo Release 20-2-2011
But I had with both ones the problems as described above...

Battery status not working correctly eather
I have the same issue. Using the last kernel .32 and android 2.3 but have the same performence on 1.6 and 2.2 After a day my battery go to 70% decrementing smoothly with -1-2%. And after a day go from 70% to 15%. That is annoying do you have a fix for that?
Thanks

Until now, I didn't find a solution!
Does anybody have an idea?
At the moment I think whether I'll switch back to WinMo 6.5...

I found a solution!
I tried the following kernel:
2.6.32.9 [email protected]
In my opinion more important: I tried it before with an to 450MHz over-clocked kernel. Now I tried it with the mentioned kernel without overclocking and everything works!

Best Desire ROM for optimized battery life?

Hi all,
My partner has been experiencing a few issues with her 'stock' Orange branded Desire, not only being affected by calls dropping and Data being unreliable [sometimes works, sometimes doesn't], but also pretty poor battery life.
On that note, we think it may be a good idea to root her Desire and apply a custom ROM. Are there any ROMs out there which specifically target battery optimization?
I am assuming a new ROM/radio will help resolve her call/data issues, so battery is the next priority to look at.
I'm thinking CM7.0.3 is the safe bet [moreso because that's what I'm running on my Legend ] but is there a ROM out there in the Desire community known for great battery performance?
On a side note, if you can also recommend the best radio to flash [unless it's part of a ROM already] that would be cool.
Thanks in advance,
c_man

At first reducing the brigthness-level, turning off 3g/hsdpa, gps and wifi (sleep policy to "never" [settings > wireless & networks > wifi settings > press menu > advanced and set wifi sleep policy to Never; press menu and save) and only turning them on when needed will improve battery life.
A rom with a good battery life is redux:

I have installed it myself with the kernel in my sig. Especially the standby-battery-power is really impressive. IMHO all small aosp-roms like e.g. cm7, devnull, oxygen or redux will have good battery life. Furthermore, i good kernel with appropriate settings becomes important.
But final one can say, the battery life is most related how much you use your phone.
Hope, this could help you.

If your wife is used to the Desire as it is (inc. HTC Sense) then I would highly recommend LeeDroid.
Its well indexed and offers good battery life. The fact that it's based on Gingerbread (2.3.3) is a big help for battery. As far as I know Orange Desire is still on Froyo?
The big benefit with LeeDroid is that if your wife isn't as keen on trying to learn to use stock and likes HTC Sense, she will not notice any difference. It would be worth putting an ext partition on the SD card as well so she wont run out of room for apps.

I have installed 7.0.3 and my battery life drains super quick. All i have enabled is mobile network. So if you ask me.. .I would say CM 7.0.3 is not a very good batt saver.

Im using Redux at the mo
3ma drain on standby with GPS and BT enabled
ManU Havs Axi kernel undervolted with Vipermod
I found GV to be very good on battery drain too...

In all fairness you wont believe the difference in battery life between stock and a custom rom imho

Thanks for the replies so far.
@MatDrOiD - thanks, currently its between CM and Redux.
@JokerNJ - She doesn't mind having to use 'pure' Andoird, she's used my Legend on CM7.0.3 and know's its not massively different. We'll take a look at LeeDroid...
@alexander7567 - this is not what we wanted to hear. CM7.0.3 has done wonders for my Legend...

Positively or negatively!?

@MatDrOiD - you mention that you run Redux with Kernel: 2.6.35.9-Redux-SVS_BFS + ULV-Script.
Is there a recommended kernel for Leedroid and also for CM7.0.3?
This is slightly offtopic but can you supply a link on how to install/flash a kernel? I've not done this before [for my Legend].
Also what radio should I go for her Desire?
EDIT:
Doesn't matter if the radio and kernel you suggest are not the latest/greatest/cutting edge, but as long as they are stable and known for good performance, that is good enough!

Mobile network is one of THE battery killers at all. Turn it off and just turn it on, when you really need it.

I do not know a recommended kernel extra for leedroid. For CM7 (or aosp-roms in general) the manu-kernel is very good:
http://forum.xda-developers.com/showthread.php?t=883598
Furthermore the couttstech-kernels are very good (they can be used for sense-roms as well:
http://mirror.couttstech.com/android/index.php?dir=bravo/kernel/
But i would say, search for the corresponding threads of this roms, i think you will find a good kernel.
Flashing a kernel is very easy:
1.) Download the kernel you want to flash as zip and copy the file without extracting on your sd-card
2.) Go into recovery
3.) Do a nandroid-backup, just in case.
4.) Wipe cash + dalvik-cache
5.) Flash zip rom sd-card like you would flash a rom
6.) Reboot
You are done.
I would recommend to use this radio, which is the mentionend recommended radio in the corresponding thread for the rom. E.g. for leedroid it's 32.56.00.32U_5.17.05.08. If there isn't mentioned any recommend radio, just use the radio which comes with the rom. Nevertheless, you are free to update to the respectively newest one:
http://www.mofirouz.com/wordpress/2011/03/htc-desire-radios/
You flash a radio like you flash a rom or kernel. But when you do this, DO NOT TOUCH YOUR PHONE UNTIL IT'S FINISHED. With flashing the radio you update your desire's hardware. If there somehting goes wrong, your desire will be bricked probably. So before flashing the radio, check the md5-sum of the downloaded zip.

Thanks! I didn't know the method to flash a kernel was the same I've done radio before for my Legend so that's all good.
Now all that is left is for my partner to choose a ROM and away we go...!

Thanks, happy i could help. But after your last post i edited the procedure for flashing a kernel and named another recommend kernel. Take a look at it.

You are free to choose. But this is the recommmended and most used one (also by developer).

Danke schön...!
Fingers crossed for the root [will use unrEVOked 3 - this shouldn't be a problem even though her Desire is Orange branded as I understand it - someone please correct me if I'm wrong]
You Desire guys are lucky to have so many ROMs/Kernals to choose from.
For us Legend guys the choice is almost made for us [and I sold my Desire to own a Legend ].

Another vote for LeeDroid here for the Desire. I have been using LeeDroid since I got mine and have never had a problem with my battery life at all. I can go for two days at normal usage without a charge. Even with heavy use I can go a whole day. I charge mine each night in a dock on my bedside.

Thanks FlareHeart, is that running the radio/kernal that arrive with LeeDroid too? No other mods?
Now it's up to her to decide if she wants a ASOP ROM or one based on Sense .
Hopefully we'll root tomorrow...

I used Amethyst a bit before the dev jumped ship to Nexus S. It used Coutt's kernel for it and the longest I got out of a full charge was 2 days. And that was general usage (few texts/phone calls a day, push email, Facebook/web browsing).
Using Oxygen now and I frequently get over a day and a half on general usage with thalamus's kernel.

best Rom for desire
I have used devnull then gingervillain, all vanilla roms. but without sense there is no sense!!. thus I went for insertcoin 1.0.5. which is stable, very nice. u need ext4 partition. 500 mb ok. use minitool partition wizard for Windows. everything is working fine.

[Q] how to overclock HTC Wildfire?

HI,
I want to overclock my HTC Wildfire for batter gaming performance. My device details:
Rooted and running SUnAabh v1.1 ROM
Baseband: 13.55.55.24h_3.35.20.10
kernal 2.6.32.21-g0f9e.... tue noc 30.....
Build Number: vibhu's rom froyo
I am have used SetCPU app but it not working ?
Can any one tell me how to overclock my device.
Thanks

Overclocking wont do much good in terms of gaming performance. Our device lacks gpu which is why games don't work as they should.
Overclocking needs an overclockable krenal. I am using kwbr rom which is sense based as is sunaabh. I use rempuzzle kernal for overclocking on this rom. You can get it from the rempuzzle thread. Alternatively you can use Hcdr kernal.

guys please stop posting in the wrong thread...this is the development thread...move it to the the thread......
and kindly try to use the search button....it solves all your quarries

Has this thread changed section or was I that sleepy I didnt notice it when I replied?? Wierd
Sent from my HTC Wildfire using XDA

Use Cyanogenmod... Performance options (which include overclocking) are integrated inside the rom. Easy as 1 2 3

I want to overclock my device on same ROM, what I need to do ?
Can overclocking improve the games performance ?
I am playing Tekken 3 on my HTC Wildfire Buzz, by using FPse emulator and ISO image of game.

so u have root, and a custom rom. The only thing u are missing is a custom kernel, i think. Flash a kernel that supports your rom and can be overclocked. Than setcpu will work.
The game will run maybe a bit smoother. a gain of 1-5 fps hopefully. Maybe more, but i dont know for sure.

Wow this is an old rom, not seen this pop up for a time.
I used to use fpse(the whole reason i rooted my phone lol) and too played tekken.
Overclocking does help a little but dont expect to be pulling off special moves lol as response is not great even at highest o/c. Mess around with fps in the game/app (cant remember how it works) i think i used 25/30 i got it running quite good at one point but still laggy.
P. S stick with a sense based rom for fpse as it works best on sense on wildfire.

So can you tell me what's new and stable ROM for HTC Wildfire that improve performance.
What I need to do for fast and smooth play of Tekken 3 ?
Reduce frame rate or anything like that ?
Or can you recommend me any good game of PS3 that smoothly run on HTC Wildfire ?
Thanks

Trial and error really but 1st i would flash an o/c kernel. Head to dev section sticky, complete wildfire guide and try jacob flash to any rom kernel or rempuzzle thread and flash rempuzzle kernel.
Then its about testing which values work best for you,use setcpu to adust carefully as setting o/c too high has been known to cause boot loop for some. Go up in settings in parts not straight into 768.good start would be 633 test, then 652 test...... Etc etc
Ive already mentioned about framerate so test different values along with o/c values.
There is only one sense rom. I personally recommend and that is rempuzzle.
Thats it you have to do the rest lol. Goodluck, hope it goes smooth.

Hi
Below is the link to Wildfire complete list of ROM, Kernel etc

Scroll down to Kernel list section to to choose the kernel that match your rom.
For Sense Froyo ROM alternatively you can use Rempuzzle Kernel to OC

[Q] ION Kernel vs HD-Kernel vs PachaRX vs4

Hi Guys!
1st i have to say that is my 1st post :'D , and my english not is very good...
ok, I want to ask you what kernel works better in our desire hd. Nowadays I have flashed the rom SVHD 2.1...
The 4 kernels are:
->HD-KERNEL T-16.1 (ION) Based on linux kernel 3.0.101 : http://forum.xda-developers.com/showthread.php?t=2195735
->HD-KERNEL T-10 (ION) Based on HTC Stock 3.0.16 (same as before but a 3.0.16 base and a older release t10) This and pacharx appears on myHUB of the rom
->MELKANG KERNEL R1 (ION) Based on 3.0.16 and with some bugs as not S2W and not OTG (idont use these things) and wifi bug at start up (need to disable and enable to work). Some People on SVHD says that this kernel is very smooth compared with the stock custom kernel on the rom (pacharx 2.9). I dont know if they have tried any of HD-kernel to say that this is the "best" i dont know. Neither I am criticizing anything, only I say that if before they have tested some another kernel with ion to say this. The link: http://forum.xda-developers.com/showthread.php?t=2560386
->PachaRX-VS4 2.9 (not ION) htc stock 3.0.16: http://forum.xda-developers.com/showthread.php?t=2129153
If anybody knows what kernel is faster and what kernel have beter battery life, pls answer this post!
And other 2 little questions:
->Can you recommend to me a good battery with protection anti short circuit and everything what must have one original but be extended battery?
Pls dont say the 2450mAH japanese battery, i have hear that this battery can explode because dont have any charging protection.
->Link2SD slows the OS and the load of apps? Always I have believed that this application was an improvement of rapidity for the system on having left more internal Free memory, but in the last flash I did not install it. I notice more speed in the load of applications.
Thank you very much to all the members of the forum of desire hd. You are the best, are doing of this smarphone of 1st OP SmartPhone generation a marvel:laugh::laugh::laugh:
