I rooted my evo yesterday, so I am still completely new to how things work. (Though I have read the forums for a while)
I know I can flash a custom rom to fix the 28FPS limit I am getting, but I don't have time to completely wipe my phone and rebuild everything again.
It's kind of looking like I just flash a kernel? but I am not sure and I don't want to brick my phone.
Is there a way to just fix the performance limitations (i.e. FPS limit) and keep my stock 2.2 and all my settings/preferences?
Thank you.
I searched but didn't find anything that made sense.
Phone:
Evo w/ stock 2.2 (UnrEVOked3 root)
You should be able to just flash a custom kernel, but I don't know how those work on plain stock. Make sure you nand first.

I have rooted stock 2.2 with Kings kernel #9. Works flawlessly. It's hard for me to go back to regular once the FPS is unlock.

Just flash the zip file from recovery. Make sure you do a nand backup before you start flashing the kernel.
Thanks for the info.
I will give it a try later.
Can I flash any kernel? Or how does that work?
I was looking at snap 8.2. Is it compatible with stock & sense?
(http://forum.xda-developers.com/showthread.php?t=733099)
Also, once a kernel is flashed can you update it without problems or doing a full nandroid restore?
Thanks again,

No. Go for Netarchy's or Kingklick's kernels for 2.2 Sense roms. Snap is only for cm6/AOSP style roms.

I'm using hero 4 on stock odex with no issues and great battery life.
Thank you.
I will read into each kernel.
Any suggestions on which is best/worst?
EDIT: Thought I would post some links to each kernel you listed:
KiNgxKernel
netarchy-toastmod
I couldn't find the link for Hero_over's kernel. The forums search function is down for some reason.
Please correct me if those aren't the correct or official links to the kernels.
with netarchy it says:
An important note for Clockwork mod Recovery users:
Clockwork Mod is reportedly not wiping correctly (ie; if you try to wipe cache/dalvik-cache/data/etc it's not actually doing it, or not doing it right)
You may want to consider using Amon Ra Recovery instead.

not wiping correctly may cause your phone to bootloop no matter the kernel(Fresh's seems to be particularly sensitive to it), you should be ok though. If it happens just keep redoing it till it works.
I'm using netarchy's 4.1.9 cfs ATM and it's working great. Smooth as butter.
king kernel is really good, thats what im on right now. medium use: 500+ texts, wifi on, data on, hour of browsing, 30 mins of music playing, live wallpaper. with all that im hitting ~13 hours and im at 8% right now. king kernel is pretty good, nice and smooth too

Wow! that is double my current battery time with stock and everything turned off to conserve power.
Should I use BFS or CFS?
Can I back it up my kernel so I can reflash it if I ever need to?

im on the latest king kernel which is BFS (the king kernel #9)
as for backing up your kernel...i dont know...(didnt know that was possible). once you unlock fps, you'll never want to go back.
edit: also forgot to add that my screen off is underclocked to max:245 and min:245. so that made a HUGE difference in battery life

There really is no generalization for which is better, BFS or CFS. Every phone is slightly different in build due to margin of error in production. Some people have great results with BFS where others do not. I tried both extensively on Netarchy and much prefer CFS (better performance and battery). Why? I don't know. It just works for me. You will probably have to do some experimenting of your own.
Edit: Also concerning recoveries, I would go ahead and flash Amon_RA's recovery over ClockworkMod just to avoid conflicts. Amon works with everything is very straightforward to use.

Rom Manager won't work with Amon_RA, will it?
I still know very little about root abilities so I would like so stay with something easy like rom manager.
And are Nandroid back ups interchangeable between recovery images?

you can use rom manager to install ra, but then all you'll be able to use rom manager for is to download roms. Which is still ok - some folks prefer it this way, because some things shouldnt be too easy, if you know what I mean. If you let a tool do all the work, what do you do when that tool breaks or is unavailable, and you have to do it manually?
ra can only be used outside of rom manager. Nands cannot be used between ra and clockwork - if you backup with ra, you need to restore with ra, and if you backup with clockwork, you need to restore with clockwork.

I don't mean to be ambiguous, but it really depends who you talk to. Some people swear by RA, and insist that clockwork doesn't wipe properly. Other people can conclusively prove that clockwork does indeed wipe properly, and use that with no issues. Personally, I use clockwork, but do all my flashing and wiping manually and not through rom manager. The only time I ever had any issues was a while ago, with an older version of clockwork.
I also think that clockwork has the benifit of not requiring signed zips, but don't quote me on that.
edit - just wanted to add that some devs will specify one or the other to be specifically used for whatever it is that you'll be flashing. So if they say to use X to flash, you better try using X to flash before asking why you're having issues
idk im new to trying kernals, but im running fresh 2.2 and im only getting 31-33 fps.
using kinklicks bfs 9 kernal
any help?
I have tried most of the kernels listed. For me, the best has been Netarchy's 4.1.9.1 cfs. It is smooth and has not had a single glitch, which I can't say for the others I have tried. The second best I tried was the Baked snack battery kernel #5.
cfs or bfs? What I found was that bfs gave slightly better benchmark scores than cfs, but I had a lot of odd problems or glitches when running bfs kernels (mainly scrolling lag in some apps, and some apps fcing randomly). haven't had any problems with the cfs kernels. Frankly, I haven't found any advantage to bfs because, while it seems to give better benchmark scores, in actual use it seems much slower and more laggy to me than cfs.
Clockwork or AmonRa recovery? I have used both, only had a problem once (boot loop), and that was with clockwork. Since then, I have always used Amonra's recovery to flash with. When flashing just a kernel just wipe cache and Dalvik cache, then flash the kernel. As long as you do not wipe data (reset) you should not lose anything when you flash the kernel.
Oh, and when you do a nand backup, it backs up the kernel you are currently using with it. So you can easily switch back and forth to test by restoring your backups.

If Ive flashed Pershoot's kernel and CM 6.1 and for some reason i decide i want to Nandroid back to my stock setup....how would i go about it. Do i have to use the PC10IMG.zip because of Nandroid not touching the kernel?

Well if you didnt do a Nandriod Backup of your stock rooted rom before you flashed CM6.1w/Pershoot's kernel you will not have an available Nandriod backup to use. Also when you do a Nandriod backup it's of the entire system including the kernel, so what ever you back up it also backups the kernel, so to awnser that question it does restore the kernel.
Next and most important you do not ever want to reflash the PC10IMG.zip image on your rooted HTC Vision unless you have true permroot with gfree, if you rooted the old wpthis.ko file way and did not run gfree, and you would know if you used gfree, then you dont have true radio s-off and if you flash PC10IMG.zip you can brick your phone, here is a link to the thread discussing the problem I am talking about:
http://forum.xda-developers.com/showthread.php?t=838484
Next if you have gfree'd your phone then you should be able to reflash the PC10IMG.zip(T-mobile G2) onto your phone without any problems, I have not personally tried to reflash the PC10IMG.zip myself and I am gfree rooted, because never found a need to, but I have found a link to a post where someone has flashed the PC10IMG after gfree with out any problems :

I really dont know about the Vibrant, but I would think any nandriod backup would include the kernel because its like a snap shot of the entire system.

Ok , I read your links the radio and kernel are two diffrent things, the nandriod backup restores the kernel not the radio. But unless you specifically flashed a new radio your phone still has the shipped radio even with a diffrent rom, like me right now Im running Enom's rom w/ 2.6.32.27 kernel, before this I was running Virtuous with evils kernel, but even after all the diffrent roms I have flashed and kernels I have flashed, I still have the shipped radio, I never flashed a new radio. So again unless you specificlly flashed a new radio you still have the same radio the phone shipped with even though your on a custom rom. And you would know if you flashed a new radio. Custom Roms do not come with new radios they use your existing radio.
So nandriod backsup the kerenl not the radio.
Correct you are Joe. Must be vibrant specific (Nandroid not restoring kernel).
Any problems with pershoots kernel for you? I just flashed it and my battery is awesome. I'm just using set CPU with no profiles.

I didnt notice any benefit or real difference from the two, plus when they first started coming out with the OC mods 1.5 and above always seemed to give people problems, so Ive always ran my phone at this speed or even a little less. Just being cautious I guess.
Okay I need to know how to backup my radios if something goes wrong. I would also like to know if myn's 5 is ready for testing. Thanks in advance.

Maybe this didn't aswer your question, but I just finished flashing Myn's RL5 without upgrading the radios.. if you flash a custom kernel (one in a few that myn's list in his OP) and DID NOT boot between flashing the ROM and the kernel, you can used RL5 just fine with the old radio.
I think the new HTC kernel that need radio update.
Okay soo you are saying that if I flash myn's rom and DON'T reboot after flashing a kernel then I won't have to worry about updating the radios?

do this :

btw, don't forget to do nandroid backup before doing that..
Thanks for the assistance. I tried the rom for ten minutes. It is was not that good. I blame the kernal that I used.

Try Netarchy's 4.3-havs-more with or without sbc.
Just fyi, i tried overclocking these and it messes with the phone not writing pictures to the sd. The first set of pics are fine, but once you connect to the computer and save them, the rest of the pics you take show up in the phone but not on the sd. It took me forever to figure this out, lol.
Good luck on finding the right match.
well since i cant flash kernels but i can flash roms that comes with kernels is possible i can customize the kernel in the rom? i mean like flashing a rom and adding my own choice kernel?
Why can't you flash kernels? You do it in recovery the same way you flash a rom - with the exception of wiping data. You only need to wipe cache/dalvik.

you dont know i try everything i even posted it on xda asking for help. i follow all there steps still same problem bootloops. i even had to factory reset twice because i was stuck in bootsceen. i used unrevoked to root but i was thinking maybe if i unrevoked it and using a differnt method to root. but i havent tryed it. so i donno if its phone or the program im using to root i donno whats the deal. i never flash any kernels because i was unable to pass the bootloop. the only way to get a custome kernel is flashing a rom that has a custom kernel.
It def doesnt have anything to do with unrevoked. What ROM are you running and what kernel are you trying to flash? Are you wiping cache and dalvik?

How did you root? May just be something wrong with your phone.
i had the same problem a while back. couldnt flash anything at all tho. had to unroot and wipe completely, and go stock for a day or two. everything has been flawless since.
well I just traded my epic for evo and im woundering how to root this phone, im confused because I have hardware version 0004 and the video I saw he had 0003, and then there two different recoveries, so idk witch is more popular with roms, Any help is apperciated
Go to unrevoked.com and use unrevoked to root your device. It is simple to do and arguably, the most trusted method. If you do use the unrevoked method, it will put the Clockworkmod recovery on your device. Although clockworkmod is darn good, I suggest that you flash amon RA v2.3 as your recovery. Instructions are very easy and installation takes less than 10 seconds to complete. Just post your questions and someone will assist you as quickly as possible.

Lots of good information in the thread below, the hardware version shouldn't be an issue anymore and it seems to be split as far which recovery to use. AmonRA has been more reliable in the past and has more options while clockwork will allow you to flash ROMs through ROM Manager.

We told you it was easy...LOL....Anyway, for a sense based rom, I recommend Myn's Warm TwoPointTwo RLS 5 and for an AOSP ron, I recommend Salvage-Mod 1.2.1. Be sure to make a nandroid backup of your current setup first to fall back on in case you don't like the roms you decide to try. After making your nandroid backup, wipe EVERYTHING except the SD card itself and then flash whatever rom you decide to try.

When I used to use the ClockworkMod recovery, I made it a habit of wiping at least twice before flashing, but with the latest amon RA recovery, I simply wipe once. Remember these unofficial rules:
Changing roms: Wipe EVERYTHING except the SD card itself.
Updating a rom with a nightly build: wipe cache & dalvik.
Changing kernels: wipe cache, dalvik & battery stats.
Anything else: wipe cache & dalvik

If you're using a sense based rom, I recommend a Netarchy kernel. I do not overclock, but many people do.You can achieve overclocking with setCPU. An. AOSP rom like Salvage-Mod has a built in setting for it.
