I was very skeptic in beginning on installing Custom Roms. But once i say the guide on how to do it and on how easy it was, its eased the pressure and i caved in a installed a Rom. Now that i have gotten the taste of playing around with my phone I want to take a crack at installing a Custom Kernal, but i have no clue how or where to start.
There are guides for installing and flashing everything for the Evo. I myself have just started using custom Roms and now i want to try a Custom Kernal, Yet i have no clue as how to flash/install a Kernal onto my Evo. I did a forum search and i didnt see anything. Can someone please guide me in the right direction on how to install a Custom Kernal. I know this is prob not the proper section to post this in but i thought if this is the place where all the guides are to Roms and other goodies why not post this here.
Also if i do manage to Install/flash a Kernal is there anyway to undo that kernal and go back to stock kernal ?
Thank You, Very Much Appreciated
ummmmm you flash it just like a rom in recovery... it doesnt get any easier than that....

Is there anything else ? If I install it will it be automatically Overclocked ??
you need set cpu to coverclock the right way buy it off the market to support the dev
I just downloaded setcpu and it looks like an extremely interesting depth app. I wouldn't even know where to start using an application like that with all if its settings. Its there a more user friendly app that does the same thing?

Its really not that bad. For now, just look at the main page. It tells you your current Mhz at the top in big letters. Then it'll say how its scaling (probably ondemand). Below that there will be a max and a min. Change the max slider bar to change the maximum speed you want the processor to work at. Change the minimum to change the minimum speed you want it to work at. I'd recommend leaving scaling alone for now. On demand just means that when the phone needs more processing power, it will automatically work faster, and when it doesn't need it, it will slow down. Setting it to Performance makes it run at the top speed continuously (this could be very harmful to your phone if you leave it alone for too long) Thats about it. If you want I can help you with profiles too.

WOW Thanks a million. I really appreciate all of your help. I dont really know what profiles are pertaining to overclocking. Also where can i get the stock Kernel from if i ever want to go back? I have the Evo with the 003 Screen but i had the version that came with the non update. Its totally rooted and everything.
question...
Ok, so do you need to do a wipe of everything when you flash a custom kernel?
(The irony is I flashed netarchy kernel 3.7.8 about 2 wks ago, but was late and drinky when I did it, and can't remember if I did all that. Wanna flash his new 4.x kernel)
Thanks in advance.

Hey, thanks. I just couldn't remember if I did a full wipe of everything before. I now just wiped cache, and dalvik, and it worked without a hitch. Flashed 4.0 kernel. Crazy fast. But, now wired tether for root is no longer working. If anyone can get it working in froyo, please let me know. I've searched and find nothin. Don't want pdanet or easy tether because they require the host to have special drivers, wired_tether_for_root_users works on anything you plug into, no extra drivers reqd. Just doesn't work with newer version of kernel. Anyone knows anyhow, please fill me in.
Thanks to all
For the people that want overclocking, here is your chance. I took my standard voodoo kernel, and put in the stuff needed to overclock it. Thanks to nemesis2all and his OTB kernel from the Fascinate for the code needed to get this to work. Also, use extreme caution when using the higher clock speeds. The stock "max" voltage for the CPU is 1300mv, and 1500MHz and 1600MHz are both at 1500mv, so it's heavily over-volted at the top end. By default, the system will boot to 1000MHz and you need to set the speeds you want in Voltage Control App. I don't personally use this because I think overclocking is useless, so any bug reports need as much information as possible, or they will be dismissed and not looked into at all. If you run into an issue with the system locking up, odds are that you have undervolted to much for a given clock speed. Other than that, you're on your own. Same FAQ applies as the regular PBJ kernel, so look there until I get a chance to post it here as well.
Installation Instructions:
1. Download zip
2. Transfer to SDCard
3. Reboot into recovery, you'll need to have CWM if you don't already
4. Install zip from SDCard and select the zip you downloaded.
5. Reboot and enjoy

If you are experiencing problems, I need detailed info to be able to fix it or help you out. Failure to provide detailed info will mean I'm just going to ignore your problem as user error. Details would be something such as which kernel you are flashing (filename) and steps to reproduce the issue. Also, if you used any other kernels that had the same problem or didn't have the problem.
DISCLAIMER
By downloading and using the kernels, this signifies that you have read this full post and the FAQ before reporting an issue. You also take all responsibility if your phone breaks or your warranty becomes void (which, if you're flashing this, it already is). I offer no guarantees as to anything working, though I try not to release broken stuff, it happens sometimes.

Go into a Terminal Emulator on the device and type Mount. 3rd or 4th row on the list should show ext4. If it does then lagfix is enabled. If you do not see Ext4 and it says rfs still then it is not enabled.

Well it's definitely enabled. I just must have set the CPU settings poorly because this thing is crawling right now, I can't even scroll through the app drawer!
I've been trying to CWM back to the other PBJ kernels however my phone hangs on reboot, I'm guessing because those need to be flashed with Odin.

Just curious as to why you think it's useless. I am sure you know some thing that I don't so your opinion matters to me. I love the fact that I can overclock, but if it's not needed then I might not bother. I know it did make a difference for my DX.

Use a program like CPUSpy that shows you the clock speed stats of your phone. >75% of the time, it will likely be in 400MHz or less, this probably approaches >90% if you say 800MHz or less, especially if you are not a heavy user. At that point, why overclock your phone? To get the overclocking stable, you need increase voltages across the board, and despite undervolting, you'll never get the same power usage as you can with a non-overclocked kernel as some of the voltage changes you can't revert. My opinion is that while overclocking can smooth some stuff out, for most day-to-day usage, it has no practical benefits and only causes more battery drain than you would otherwise have. Given how precious battery life is these days, why knowing make your battery drain faster?
it's funny you say that becuase i noticed with ludeboy's kernel that when overclocking system panel very rarely showed my phone running over the stock speed. Usually it was as you stated some where around 800mhz..I understand what your saying...Thanks for the quick response.
So what if we run stock clock...but undervolt? Do you think we will see any batt savings?
Backup SD and app data b/c crashing/freezing can corrupt files.
Edit: Also keep Voltage Scheduler Remover on your phone just in case.

Potentially, yes, but you may lose stability.

I love it. I can deal with a slightly shortened battery life. I wanted to OC because a lot of the more intense games don't run as smooth as I would like. With OC, its all butter. Thanks!! I have mine set at 1400, and it really didn't improve my quadrant scores, but there's a noticeable decrease in lag going from one app to another.

You would see better battery life at stock clock speeds if you just used the standard (ie. not overclocked) kernel I built.
Just wondering if you're going to branch off development of PBJT w/o overclocking separately - or if this is going to be built/rolled into future releases?
I'm on board with not thinking it's necessary - though I can see how the tinkerers and speed demons would love it. (And all the more power to them, literally)
I don't know imnuts, I always noticed when I forced the phone into a higher overclock it always seemed quite a bit snapier.
Keep it on conservative. Interactive is buggy.

This will remain separate from the standard kernel most likely. I will see if I can build off of this source without overclocking and have it work, though I don't know if it will. I want to keep them separate for stability and battery life reasons.
Can anyone explain to me what kernels are what is their function? I noticed that the update did not change my kernel. Is that a bad thing that they did not include a new one in the update? Also I am voinv to be installing xboarxers stock. Rom first to root the phone and I want know if I should chance the kernal and what effect it will have. I am taking small steps because want to understand what I am doing. Thank for any help you guys can give me.

The kernel is the lowest point in the system. It controls how the software communicates with the hardware: how the CPU behaves, how the buttons behave, how the screen functions, etc.
The main use of custom kernels is to Overclock and Undervolt. OC means pushing your CPU to be faster than it was ever intended to be; you get better performance but if overclocked too long, it will be damaged. Worst case scenario, you will literally melt your motherboard. But this is only a danger if you leave it overclocked 24/7 and constantly push the CPU to its limits (playing 3d games for instance)
Faux's kernel can OC to 1.5 GHz and Morfic's can OC to 1.1.
The next common use is Undervolting, which means giving your CPU less electricity than it would like. This again is extremely dangerous if not done properly, but yields noticeably better battery life. Morfic's is the best for UV IMO, though you cannot change the undervolting, he has it locked into what he has found to be the best. And this isn't necessarily a bad thing, as too much UVing will cause potentially serious stability issues with the device. It's not nearly as dangerous as improper OCing (it won't permanently ruin the hardware) but it is a danger. Faux's lets you UV to your heart's content.
Faux's is better if you want performance, because it has higher OC. Morfic's is better if you want battery life, because it has better UV and the CPU clock speeds themselves are better tuned for lower speeds than higher ones.
I absolutely love my faux kernel. its at 1.4 and amazing battery life. The screen sensitivity is awesome. Honestly its all prefrence.... I won't go away from cm7w/ faux

Can you flash faux kernel on top of bionix 2
Sent from my HTC Sensation Z710e using XDA App
When you flash a kernel, you just need to know what the base of it is to pick the proper one. There are really only 3 bases at the moment:
1. Stock 2.2 That'd be faux's .5, and I know morfic has some older 2.2 based kernels in his thread.
2. Stock 2.3 (Which faux is working on now, there are a couple floating around)
3. CM7 Faux and morfic both have kernels that work here. (2.3.4 and 2.3.5 based roms use this, miui, and of course cm7 )
Bionix is based on 2.2 (Which I haven't actually checked, but I'm sure it's in the first post.)
For most of them, just read the first post, or even the title. It'll say what it's based on, and then you can flash whatever you want. Just always do a nandroid backup before, you never know if you might for whatever reason have to flash back. If you don't, you need to reinstall your rom (or manually change the kernel and modules, of course) to get back to what the rom came with.
Happy flashing.
If i am running stock rooted GB OTA, can I flash faux's latest Kernel 006 with ext4?? Or do you have to have an ext4 rom to be able to flash ext4 kernels?
Thanks.
Thanks a lot that shed some light on. The subject
So it appears that the dev will tell you which mernels arw compatible with their rom in the thread for that particilar rom. If I want to use eglesblood which is 2.3.4 or.5 xan I use tbe stock kernel? Also what is the difference between the .3 .4 and .5 in the gingerbread make is that carrier specific or moel specific like the blackbwrry 8520 is for tmo and 8530 is for sprint?
Sent from my LG-P999 using XDA App
2.3.4 and 2.3.5 are based on cm7 code, so you'd use the cm7 based kernel. (LG hasn't given us 2.3.4 or 2.3.5).
As far as ext4, it's a different file system is all. Faux's kernels mount the data and system partitions as ext4, but don't actually convert them. Morfic's do a full convert. Ext3/4 support is in the kernel, not the rom, so as long as the kernel supports it you can do it. (Which every custom kernel I've seen supports ext4)
If you want more information, google is your friend. Here is a pretty simplistic explanation of the ext2,3,and 4.
http://www.thegeekstuff.com/2011/05/ext2-ext3-ext4/
As for the differences, 2.3.3 to 2.3.4 had some major framework changes. 2.3.4 to 2.3.5 seems to be only minor bugfixes. If you want full changelogs, I'd google them.
So if I want to use eglesblood then I have to change the kernel too? Do I have to do it separately or is it included in the rom?
Sent from my LG-P999 using XDA App
You never *need* to change kernels. Using the kernel that comes with the roms works just fine. Only time you need to change kernels is if you want to overclock, (never really saw the point in it, and quadrant benchmarks are useless.) want tun or cifs support, undervolting, ext4, etc.
If you don't need any of those things, or don't know what they are, just stick with the kernel that comes with the rom.
Okay that's cool so all I have to do is put EB on my SD card and flash away I am thinking about starting simple first with either xboarders stock or tweeked

Hello,
FIRST OFF!
This thread is NOT for discussing whether or not benchmarking is useful. If you feel the need to flame me or anyone here for CARING about benchmarks, then go find another thread to piss in! I made this thread to clean up Faux's thread as it was taking over.
Ever since moving to any of the newer CM7 updates, I have noticed extremely low benchmark scores on CF Bench. When on CM7-1 with one of faux's kernels, everything is fine. (Cf Bench = 7000)
When I say low, Im talking 4000 on CF Bench despite OCing to 1.56Ghz. That is far below what the Sensation STOCK is measured at...
Notes:
1-Scores can be all over the place. At one point, I got a 6400. This would immediately become a 5000, and then back to 4000 range.
2-I have tried using three different methods of controlling the clock. (System tuner by 3c and fauxclock, both recommended by faux for his kernels, and then the CM7 performance settings). Fauxclock had the best outcome, but EXTREMELY unstable!
3-I have done NUMEROUS restarts along with cache clearing and dalvik clearing. I even pulled the A-Bomb out and used the superwipe script to start fresh. After the a-bomb, I DL only what I needed to test with...
4-My phone feels laggy, which goes along with the crappy scores.
At this point, I am restoring to my trusty Alpha 1 + faux kernel. While that works, I feel I will wind up getting left behind.
What could cause this? What are some things I may have overlooked? Others DONT have this problem, at all.
Matt
well i will say benchmarking isnt a totally conclusive. although there isnt any other method of tangible scoreing as of yet. However i will say that if your phone is laggy then your benchmarks are a good way to test why.
scoreing varies when you have active apps in the background unknowingly.
also if you flashed a new rom and kept your old kernel that will dramatically reduce your scores. check out some other kernels for your new rom and see if that makes a difference.
try flashing back to stock and deleting the kernel, then flash the CM7 rom without the kernel in your system and run a test.
theres a lot of things that will change your scoreing.
let me know what you get out of this.

I came from ARHD with fauxs kernel. I did a superwipe and then flashed cm7-1 and then flashed fauxs kernel. Everything was great until I tried any of the new CM7's...Just tried cm7-6 and got a WHOPPING 3000!!!!!!!!! YAY!!!!!!!!
I knew it would be low, just playing with the phone. I find it so weird that going back to cm7-1 fixes everything.
Either their new updates kill my performance for whatever reason, or going from one cm7 build to another is a no go. (I did a superwipe just to be sure when going from alpha1 to alpha 5).
Damnit.
If it werent for seeing others with good scores, I would blame cm7 or faux's kernel. Its got to be some little quirk with my phone. (And a few others).

I recently rooted my P999/G2x and installed CM7.1.0.1, and am extremely happy with it. Am looking to tinker just a *little* bit more, but have some questions... I have LOTS of answers on the forums, but am somewhat skeptical about the currency of some of the information out there (let's face it, stuff changes fast!). So, down to it:
Kernels:
- Did CM7 overwrite the stock kernel?
- I understand the benefits to changing the kernel; what about drawbacks?
- Does CWM back up your kernel with Backup and Restore? If not, how do you do this?
- Recommendations on a good, reliable kernel to use w/ CM7? I am looking at faux123's CM and morific's Trinity. Thoughts?
OC/UV:
- Can you OC on stock/CM7 kernel?
- What is the best app to manage OC/UV? I have my eye on setCPU, cpu Master, and Android Overclock (JRummy16)
- Any recommended settings for the G2x? Any settings to avoid? My plan is to incrementally adjust, but don't really have an idea as to where to start.
Thx in advance!
- Did CM7 overwrite the stock kernel?
Yes
- I understand the benefits to changing the kernel; what about drawbacks?
Since not all the chips are made in the same way, you could soft brick your phone if you try to flash an undervolted kernel. This is the way mine is, and it's somewhat irritating but not all that bad using the stock voltage and overclocking to around 1.4ghz rather than 1.5ghz+. Also, battery life should be expected to be less with an overclocked CPU. It's up to you to decide how you want to run your device.
- Does CWM back up your kernel with Backup and Restore? If not, how do you do this?
Yes, backup creates an image of the entire thing. Before you start making changes, always make a backup so you can revert to previous settings should you soft brick your device. Make a backup, clear cache/dalvik, flash the kernel and reboot the phone. First boot times will always be a little longer when flashing a kernel, so be patient and don't pull your battery right away. For me personally, if it hasn't done anything noticeable after about ten minutes, I pull my battery. Reboot into recovery and restore from the backup you made. If you started off trying an undervolted kernel, time to try the standard voltage now!
- Can you OC on stock/CM7 kernel?
No, and you'll be able to tell once you flash CM7 and use SetCPU (or whatever you use) and see the max is still at 1ghz.
- What is the best app to manage OC/UV? I have my eye on setCPU, cpu Master, and Android Overclock (JRummy16)
Personal preference. I think probably SetCPU is used by most people including myself.
- Any recommended settings for the G2x? Any settings to avoid? My plan is to incrementally adjust, but don't really have an idea as to where to start.
If you want to be safe just start out at 1ghz. If you have no random reboots with your kernel then move it up to 1.1 or 1.2 and see if it's stable there. Personally, I just went ahead and overclocked to 1.4ghz. For the most part people don't really have problems with this I guess. The problems usually lie in whether or not you are undervolted and by how much. If you find your device can run an undervolted kernel, I would just leave the undervolt settings the way they are. As I said, I can't run OC/UV and have to use SV, so I never touch any of the voltage settings.
Hope this helps!
Using eagle blood (cm7 based) with faux kernel.
I heard trinity kernels may have random reboot but don't quote me on that.
Try faux kernel with oc/uv. Its very good, latest is 0.48. But if you go with the ds version (debaouch?) The battery percentages are all over the place... Lol one minute its 50% the next it may be 34%...
Use set cpu. I've uv additional 25mv across the board with no I'll effects. Screen off profile at 503 mhz max and some other profiles will have you getting 24hours easily with normal usage.
Make sure test it out before you "set on boot"...

I tired using DS OC/UV Kernel Version 0.4.8 kernel on my g2x running the latest stable release of CM7 1.0.1. Followed all the necessary step of wiping cache, and darvik but when I reboot, I get the blue lg sign after which the screen just black out and its stuck like that till i pull the battery out. Any one know what I may be going wrong here? ? ?
Trinity ELPmax with Phoenixblood is the best combo. Trinity batterylife is amazing. When i leave the house my phones battery is 100%. 11 hours later (I when i make it home) my battery is always under 60% but never less then 40%. I play music as soon I leave the house, and till I get in the house. I also turn of data when not using and have setscpu set to 900mhz max and screen off profile set to 432 max 216 min.

- Any recommended settings for the G2x? Any settings to avoid? My plan is to incrementally adjust, but don't really have an idea as to where to start.
If you want to be safe just start out at 1ghz. If you have no random reboots with your kernel then move it up to 1.1 or 1.2 and see if it's stable there. Personally, I just went ahead and overclocked to 1.4ghz. For the most part people don't really have problems with this I guess. The problems usually lie in whether or not you are undervolted and by how much. If you find your device can run an undervolted kernel, I would just leave the undervolt settings the way they are. As I said, I can't run OC/UV and have to use SV, so I never touch any of the voltage settings.
Hope this helps!

+1 to everything you said
just to add if you want to over clock then go with faux or trinity. the cm7 kernel is faster then both @1000mhz, if speed is what your looking for without the dangers of oc. The stock cm7 kernel also lacks the ability to under volt soo battery life might not be as good though

I tired using DS OC/UV Kernel Version 0.4.8 kernel on my g2x running the latest stable release of CM7 1.0.1. Followed all the necessary step of wiping cache, and darvik but when I reboot, I get the blue lg sign after which the screen just black out and its stuck like that till i pull the battery out. Any one know what I may be going wrong here? ? ?

Format data/ factory reset.
Wipe all cache.
Format system. (don't forget)
Flash cm.
Flash kernel.
It may take a while for the system to boot, 5 min. Let it load, and reboot, enjoy.
