Looking forward to it. I had to look long and hard to find anything like this. I'm new to rooting and would love to see which roms people like most rather than trial and error. I can't believe how many are out there!

so let me start by saying that akazabam definitely knows what he is talking about. that guy is the resident guru around these parts though he has not been around much lately. and it is hard to take his post out of context like that. not sure what other post he was refering to. do you have a link to the thread his post is in.
actually what he says is true. his main thing was that if you flash a rom that has mods in it like a2sd and then you flash a stock kernel (the one release from htc) then it could break some mods like a2sd.
the rom and kernel you are talking about are fine. just flash the rom first and get it set up then go back to recovery and wipe dlavik cache and cache and flash the kernel.
really the best place to learn all of this is to read the http://androidforums.com/evo-4g-all...ooting-dummies-guide-gingerbread-edition.html. there is sections on flashing roms and kernels.
The problem with all (or most) of the flashable stock kernels you'll find is that they are provided as a boot.img. Pretty much every custom ROM out there has a modified boot.img. Unless the ROM is stock or meant to be stock with very, very few changes, you should not flash a kernel packaged this way, or you will undo some changes. For example, if a custom ROM supports a2sd, even if it comes with the stock kernel, there are modifications done to the boot.img to support a2sd. If you flash a custom kernel, then flash a stock kernel that is just packaged in a boot.img, you'll break a2sd. That being said, if you happen to find any stock kernels out there, I highly recommend you not suggest people flash them unless they are on a completely stock ROM. I do remember myn providing a flashable version of HTC #17 in modular format (what you want; not packaged in a boot.img), but I can't seem to find it now. Anyway, you can tell pretty easily if a flashable zip is just a boot.img or not. Just open it. If there is just a zip file at the top level, and in that zip is a boot.img file, then it's going to flash a whole boot.img. If you open the flashable zip, and it has just a directory named kernel or something like that, and in that directory are other files, but no boot.img to be found, you should be fine.
All that being said, what users need to do is just flash their current ROM without wiping data to get the stock kernel (or whatever came with the ROM) back. That will undo all other mods, but it's the easiest way. Another option would be to take the boot.img out of the flashable zip of your current ROM, package it in a flashable zip, then just flash it. That would certainly do the trick, but it would be really impractical to make flashable zips for all ROMs and versions.
In any case, it's not impossible to make a flashable zip that has just the stock kernel, but someone with more knowledge than me would have to make it, and I haven't seen any others out there beyond HTC #17. Those that know how to do it always just suggest to reflash your current ROM, anyway.
It's actually post 8 on this thread. http://androidforums.com/evo-4g-all-things-root/284413-roms-kernels-download-page.html#post2329913
I'm not sure I really understand what he's saying.
A ROM includes a kernel, a kernel image and software?
If you flash a kernel that is just an image then it messes up the kernel image you have from the ROM? Is that what he's saying?
Why doesnt the kernel image match the kernel?
Speaking of links in the dummies guide, I just saw this post by smelkus about his recovery modified for s-on folks.
Thought it might be useful....look at post 261

) I haven't been that good at keeping up anymore with AF. I need to get back up here, lol

I haven't been that good at keeping up with AF recently. I need to get back up here, lol
I'm definitely in the works of getting another phone, however. You guys might knock me for this but it most likely will be the Samsung Galaxy S II Epic 4G Touch. Why? 1) I work for Sprint (now) and the LTE towers aren't going to be in my area for a long while (major cities/areas first - common sense) so I might as well utilize WIMAX which is in my area until I get another upgrade. Then I'm sure LTE will be in abundance all over the country even more so than WIMAX 2) According to a tech friend, the LTEvo and the S3 can't turn off their LTE radio without turning off the 3G because it's on the same toggle or it's in the same setting as 3G data (I'm not quite sure what the source said for this). That seems like a MAJOR battery drain right there. Letting an LTE radio sit constantly searching, not good. 3) It's not a bad phone. Comparing that phone to a couple of the new ones, it gets pretty great battery life. Anywho, I'm rambling.

Well, good to see you around here too!
I have the Eltevo and my 4G as well. Not likely to get LTE around here either for a while but no biggie for me.
congratulations on whatever phone you get, hope you get one you like and that has good dev support like the Eltevo does.
One thing, you CAN turn off LTE mode and leave CDMA on. It can be in either both or CDMA only.
I leave mine in both as I heard it may help with the 3g speed. Haven't noticed that it did particularly but I did notice that I could talk on the phone AND surf the net at the same time, just out on the street, not having to be on wifi. Don't know if LTE on had anything to do with it or not.
Also, I have not noticed ANY drain on the battery from leaving LTE on in a non LTE network area. Wimax does chew up the battery, I have noticed, in a wimax area or not, but LTE doesn't seem to have the same effect.
Battery life seems to be ok too!![]()
actually, i just tested it, i was in cdma only mode, not on wifi, i was on a call and surfing the net at the same time!

The LTEVO (and I assume the S3) CAN shut off the LTE radio without losing 3G connectivity...but there's no reason to shut it off. The LTE radio has a negligible drain on the battery life. By the time you factor things in such as normal connection strength and all the other variables I'd say it makes no difference. These arent the Wimax 4G radios that are known for killing the battery. The phone sleeps at -3mAh with the LTE radios on.
Having no LTE in your area is a relevant point. I have never had 4g Wimax coverage so that doesn't really matter to me. When I move to Minneapolis I'll have it in october/november. I buy my phones with hardware specs being the number 1 thing in mind.
Edit: looks like dustwin posted this up too.
You can talk and surf at the same time on 3G with the LTEVO.

well the first few days you have your phone you are going to wear it out messing with it anyway. like when you flash a new rom, you can't tell anything about the battery.
Then you will want to root and get it s-off, can be really simple or a bit of a pain, depending on drivers loading and such. Then, the new Evo, has a boatload of people developing stuff for it, so that will keep you busy...
Eventually you get a little more stable in your usage, and the battery lasts great, depending on the rom and usage, of course.
i have started messing with Tasker, and Mike at xda has put out a new version of the Mean rom seems like every day, and they are great stuff too.
phone is too thin for me without my Otterbox. makes it all good though, don't have to worry about dropping it, easier to hold and operate too.
