You're going to want to wipe dalvik and cache (as you always should when Flashing something). Possibly even battery stats if you want to play it safe

Treat kernels just like you do roms I don't want you to be paranoid

Don't wipe data
Do wipe cache
I never wipe battery stats, but I suppose you could.

Exactly...
Just make sure to ONLY wipe cache and dalvik cache. This will ensure that the kernel is flashed correctly with no traces of the previous kernel. Again, like said previously, treat flashing kernels as you do flashing ROMs. It's easy, and if anything goes wrong (rarely ever happens, unless you use a kernel not designed for the EVO, LoL) then it can always be undone by reflashing
Good luck and enjoy! You'll be fine br0

For completeness....(? it's Christmas)
Due to some possible wipe (recovery) issues:
Wipe cache , twice.
Wipe Dalvick , twice.
IIRC

Thanks all for your help. I looked at a couple of different kernels, which one do yall think is the best mainly for the battery anyway?
SWYPED FROM MY EVO

I'm running SBC-net 4.2.2. And it runs great for me. Good battery and is smooth.

Do you have a link that I can download that kernel?

Return after MIUI

I just sifted through the forum and couldnt find anything so is there a special thing you have to do if you want to return to Sense after CM 7 and MIUI? Or can you just flash a Sense rom?
I remember on the Fascinate we had to ODIN a stock ROM after because of MTD BLM.
No you can just flash. Well you should clear data/cache.
I normally wipe data factory
wipe cache
format system
clear davlik
clear battery
then flash.
Might be to much but thats normally what I do and Ive never had any problems.

I would definitely wipe all those, especially from an AOSP Rom to a Sense Rom
FWIW, I do the same, except I don't bother to wipe battery stats.

Make sure you return to a stock kernel as well (if you changed it). From what I have heard, sense and AOSP kernels are not compatible with each other.

quick kernel question

i apologize for my noob question in advance.
i'm new to the whole flashing ROMs/kernels and what not scene. im interested in flashing the newest energy rom and i have seen a lot of people saying that the anthrax kernel is amazing with the energy rom. i know how to flash a ROM, I'm just not sure what to do about the kernel. so i was just wondering if somebody can give me a quick tutorial on how to flash anthrax's kernel with the energy rom.
again, i apologize for my noob question. any help would be much appreciated. thanks

You flash a kernel like a rom.
Wipe, Flash the rom, flash the kernel, reboot.
Should be good after that.
Make sure the kernel is for Sense if you are using sense or AOSP if you are using AOSP.
SetCPU will let you configure the kernel.
thanks for the quick response xnotta. i just want to make sure, i wipe everything, meaning dalvik, cache, and data, right??
On energy wipe ONLY dalvik cache mount data in recovery flash kernel unmount data reboot

If you are already running the rom(Energy) then you can just wipe Cache and Dalvik then flash the kernel(anthrax).
You only need to wipe everything if you are installing the rom(Energy) fresh.
Sorry for the confusion.

I always wipe with a ruj format all before I flash a new rom.. But as far as flashing modems and kernels I never wiped cache and had an issue.. But it won't hurt to wipe it before you flash a new kernel or modem

In fact some roms have issues when you wipe before a flash, take captainmorgan's miui port as an example, some of us had nothing but issues related to wiping everything first lol, its hit or miss on that so most definitely check the op for all your flashing info needs

agat cwm said its safe to use with ics ff18 but when i do a wipe the only thing that comes up is to wipe cache partition no other choices is that ok
also is it safe with agat cwm to use the wipe data/factory reset with the brick stuff thanks
Modems no, kernels always.

Correct. Always flash cashe and dalvik before flashing a kernel. Modem no. Just update prl and profile and you're good.

Flashing Kernel... advice

So I'm going to flash the Trinity kernel to my Wind Mobile S3 and i'm wondering... what all do i have to do before and after? from what i understand before i just have to wipe cache and dalvik cache, then install zip... what about after it is installed and rebooted?
do i have to do anything else? if so, what, and how (if it's not self-explainitory)
and if this is in the wrong place, i'm sorry mods, i'm pretty new here, and i just thought this would be a good place to post because a lot of people in here seem to do kernel stuff...
thanks
yes it's a wrong place to post here in development section.. but for your question yes, for better result you need to wipe partition and cache then flash the kernel of your choice.
Sent from my SGH-T999 using xda app-developers app
Its in the wrong place LOL! To answer your question...
1. Make sure the kernel you are downloading is for the correct rom (CM9/Stock)
2. Make a nandroid in recovery before flashing, its better to be safe than sorry.
3. Wipe cache
4. Wipe davlik cache
5. Flash kernel
6. Reboot wait till you get to the lckscreen. Be patient it has to optimize system
7. If you want to OC download setcpu in the market, its free here for members you just have to search.
8. Test and run the whole day...there's alot of kernel's you decide which combo rom/kernel you like!
9. Enjoy/Profit :highfive:

Great tips, how safe is it to OC with setcpu and at what speed?

[HOW-TO] Proper method to flash a ROM

First off if you're on ANY recovery that isn't CWM 5.0.2.7 you DO NOT NEED TDJS SUPER WIPE OR CACHE WIPE SCRIPTS!!!! Seriously stop flashing these people you're filling up threads with problems caused by both of these scripts and bad flashing methods. Here's how to PROPERLY flash a ROM..
If on CWM 6.0.x.x
1. Wipe factory data/reset
2. Wipe cache
3. Go into mounts and storage
4. Format /system
5. Format /data
6. Format /cache
7. Enter advanced
8. Wipe dalvik
9. Flash ROM then gapps
10. Reboot and let the ROM settle for 5-10 minutes if flashing TW ROMs, this step is unnecessary for AOSP based ROMs.
11. (Optional) if flashing a new radio flash AFTER the ROM has been initially booted for the first time. No wipes are necessary when flashing a new radio but it HAS to be flashed after the ROM is loaded and settled in. Flashing a radio first and then a ROM has caused issues like the phone not even recognizing there is a network for it. ( phone remains in emergency mode )
If you're on a Cyanogenmod nightly a full wipe IS NOT REQUIRED. The proper method of dirty flashing is just wiping cache, ( NOT FORMAT CACHE IN MOUNTS & STORAGE )
wiping dalvik and flashing your ROM. Simple as that.
If using TWRP 2.2+ the steps are essentially the same or use TDJs wipe scripts. They work perfectly fine with TWRP. Feel free to wipe 2x or even 3x if it makes you feel safer about your installation.
And THAT'S IT. People are cluttering up threads with issues than can totally be avoided by flashing the right way. I hope this helps some of you iron out these insane tiny quirks I keep reading about.
Happy flashing folks.
EDIT:
I forgot to note.. if you're still using one of TDJs roms or any other rom that automatically wipes with TDJs SUPER CACHE WIPE, do NOT use any other recoveries other than CWM 5.0.2.7 or TWRP 2.2+. With any other recovery such as CWM 6.0.x.x+, the wipe script breaks the roms ability to reboot properly and the only way to solve this is to use TDJs CACHE WIPE which in turn breaks your recoveries ability to work properly.

Thanks man this was needed. Yes threads get filled with this so often. I dirty flash like you mentioned accept I format system first. I also clean flash like you mentioned but never formatted cache and dalvik just system. That's good to know. Thanks
But I will add those new steps. I format system when dirty flashing because on the cm10 Site they mentioned that.
Again thanks

Sad we need to keep telling people how to flash. If you are not sure what you are doing I think you should be very careful before you destroy your expensive toy. Everyone should have an idea on how to flash and restore from a bad flash before they even root. Also as my sig says let Google be your friend people if you run into issues instead of running to a thread and clogging it up...
Thanks for post and this is a bump to keep it on page 1 and hopefully more people will notice it.
So I messed up and used the darkside scripts with 6.0.1.4 and I can't get my phone to boot, like you mentioned. It also destroyed the recovery, does nothing at all. What can I do, if anything, to fix?

Can you boot into recovery at all? If you can.. download the TWRP 2.2.2.0 zip in its thread and flash it. Its going to hang in the install process but should say twrp has been installed. At that point reset your phone by holding the power button. As soon as you feel the phone vibrate hold down both volume buttons and you should boot into TWRP recovery.

Darkside superwipe will only mess your ROMs ability to reboot on touchwiz ROMs. The only way to fix this is flashing the darkside cache wipe which WILL break clockwork mod 6.0.1.4 like the user above. Point is.. don't use either scripts at all on CWM. Wipe the old fashioned way.

I agree. even after switching to twrp I still find the script useful. But op warning about using script with cwm version 6xxx might be true. I have issue with boot when i was on cwm 6 and i had to Odin cwm 5.0.2.7 again to get into recovery menu.

Luckily enough, TWRP does this in the wipe section already when you hit system, cache and dalvik. Its an awesome and well thought out recovery!

Sub'n.
I just followed this and it answers many questions. I have great luck with CWR 5.0.2.7 and the darkside scripts. Everytime I had an issue, I would run the darkside cache script and all was fixed.
Now, since I upgraded CWR, I have had issues installing ROMS, bad recovery installs, etc. Just as you mentioned.
Got a new phone today. Flashed an odin CWR (didn't know the version). It turned out to be an older touch version. I CWR flashed the latest Sk8's recovery. I then followed your instructions. Installed JB ROM and Gapps and it was a success. Not boot loop.
Questions: What do I do if I want to wipe cache and dalvik or fix permissions in the future? What radio is recommended with the latest JB nightly?

Just go into CWM and wipe cache in the main menu and dalvik in the advanced menu. To be honest though you don't need to do this whatsoever. Only when dirty flashing a new nightly. In my experience atleast lol as far as gapps go..
