[Q] FPS Fix for Stock 2.2?

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.

what? doing the nand backup? that's just in case the kernel doesn't work you can restore to the previous condition your phone was in (so do it before you flash baked's kernel)
I'm not sure if his kernels will work on other roms though, I think I tried once

I've used it on my ROM what ROM are you using that might help.

Yes the kernel can help with battery life. You should be ok with flashing a different kernel and that ROM but as posted do a NAND backup before flashing the kernel.

Does anyone know how good the battery is for baked snacks kernel and does anyone know where I can find his kernel #6 ?

#6 has never been available for download. I used BS 1.7 on NA 4.19 and my battery was day and a half if not better with average use...seriously. I was amazed. I tried all the baked kernels and nothing worked like that.
Now I am on BS 1.8 using the same kernel and not getting near the same batt life.

I have no clue how you guys are doing it, but I have the 1.7 version with kernel 6.
I took it off the charger this morning (after a full charge), it is now almost dead, with very little use.
How do you guys do it? Your not shopping the images are you?

This is a newb question I know, I have searched all over the forums. i have the stock rom and am not interested in any of the roms since most of them seem to not have 4g working or some other things( cant wait until they do!). My question is how do I flash just the kernel? i have never flashed anything before and I just backed up everything with rom manager. thanks!!!

Wipe cache, wipe dalvic, flash like you would a Rom. Don't forget to nand first.

Edit - I'm assuming there's a specific kernel you have that you want to flash, and you didn't mean how to extract the kernel from a full Rom - also just noticed that you said you already backed up with rom manager. You may want to consider backing up manually through recovery or using amonra instead - nobody seems to know what exactly rom manager wipes when you tell it to wipe.

i think you're misinformed (or haven't searched hard enough) - most, if not all, sense based ROMs have everything working and some (i.e. wireless/usb tether, performance/efficiency tweaks, etc.). it's the cm/aosp roms that don't have everything working (yet).
flashing kernels is similar to flashing roms. there is a plethora of threads on the topic. read some of the stickies and many of your questions will be answered to get you started with flashing roms/kernels.

I have not seen any Evo roms that have the 4g working, If i did I would have just used one of those.Trust me, i have searched all over this forum and others before bothering or asking stupid questions. Maybe I am searching the wrong stuff, I will search for sense based roms, thank you.
Also, I have never flashed anything before. Still trying to figure that one out. Thanks for the info guys!

here you go:
http://forum.xda-developers.com/forumdisplay.php?f=653
all roms are there. aosp roms are usually the roms where everything is not working.
general steps to flashing (but always read the post from the developer for any special instructions):
1. download file to sd card
2a. get into recovery (either via quickboot app or via powering down then holding volume down button while powering up)
2b. navigating in recovery - volume keys to change selection, power button to select
3. nand backup
4. wipe data, cache and dalvik (only wipe cache and dalvik if you're flashing a kernel)
5. flash the rom/kernel you downloaded
6. reboot
7. drink beer
if something goes wrong, get back into recovery and restore your nand backup.
hope this gets you started.... but read, read, read.
good luck.
sorry OP - back on topic. did you wipe cache and dalvik before flashing the kernel? what's your up time and awake time (found in settings>about phone>battery). do you have any monitoring apps installed (i.e. system panel, android system info? you may have rogue app.

[Q] Not bricked but i cant boot my roms!

So my roms i download will install and boot up but once i get to that specific roms boot screen it just does an infinite loop. i then take the battery out, boot it into recovery and go back to my back up. I am not sure why it is doing this and would just love to be able to use cm7 (which did the infinite boot as well). its rooted using unrevoked and i have used a few other roms on it as well this has just been what has been happening lately. any help would be much appreciated!!

Had the same prob with cm7 #22, but 23 is working just fine, try that one. Remember the Dec said some may be broken, just fish around, but be very careful.

Sorry, meant to say the "dev" said some cm7 nightlys are experimental and may be broken. Flash to the last rom that functioned for you, then use rom manager to download the latest cm7 nightly. Which is what I'm using now and am very satisfied with.

Flash CM7 in recovery. Then BEFORE you reboot, install a different kernel
This is your best choice for CM7 - http://forum.xda-developers.com/showthread.php?t=905873
Then reboot your Inc and see if it boots up, I have heard of a couple people who couldn't get their Inc to boot up with the stock CM& kernel, no clue why though.

hahaha so i got it to work. it was rom manager not letting me go through with it all. just did it manually through recovery. but i got sm7 to install and no notification bar. hence why im laughing. just gonn install miui and give her a shot.

You are using 3.0.0.5, there is a known bug with that version and it not wiping correctly. Upgrade to 3.0.0.8 and wipe and then flash. Your problems will be fixed.
Anytime you have a question like this, please post it in the appropriate forums also, this is the development forum.

if you still cant flash roms after wiping data you could always find the latest RUU (or is ir RRU file and go back to 2.2 stock, then you would just have to run unrevoked to root and install recovery with rom manager
FOLLOWING THESE INSTRUCTIONS WILL ERASE ALL USER DATA AND BRING YOUR PHONE BACK TO THE WAY IT WAS WHEN YOU FIRST BOOTED

Don't go into the market, go into rom manager, go all the way to the bottom to "All ClockWork Recoveries" and pick 3.0.0.8 from there.

Also, use this to wipe everything, including system. Do this once or twice, then flash the rom of your choice.

Kernel

For some reason now, my phone won't take kernels anymore. I can install ROM's and everything else, but when i try and flash a different kernel my phone won't keep it. It will reboot fine, but when i go and look in the settings to see if the kernel is there it is not installed. I do the usual clear dalvik and the cache then flash the kernel. It says it installed it, but it doesn't. Has this ever happened to anyone else, and if so how do you fix it? I have also completely wiped the phone and that did not help either. I have a HTC EVO 4g. I hope someone can help me with this problem.

Hey Partyman this may sound silly but did you double check that you're not flashing the wrong kernel with the rom you're flashing?
