[Q] Should I update my kernel? - EVO 4G Q&A, Help & Troubleshooting

I am just wondering if I should update my kernel? I have been rooted since day one and I don't believe I have ever accepted any updates. I have also been running the MikG 2.1 rom for many months. The kernel I currently have is 4.54.651.1. I saw that I can download 4.67.651.3. I know there are also lots of others out there.
Will there be a big advantage to this, or should I just leave it alone. I am about to update to the MikG 3.1 rom in a few minutes is the reason I am looking.
Thanks.

Every rom you flash comes with a kernel, or it wouldn't boot. Just flash the mik rom you want, it will have what you need.
Now if you wanna ask about updating your radio, that's a whole different thing, and depending on how old your radio is, it is possible you may need to update your radio. But I'm guessing since you're on a relatively recent rom already, you won't have an issue with your current radio.
The only time I read that I HAD to update my radio to flash a particular rom was when the rom was built off a new OTA (going from froyo to GB), I believe. But that may have not even been true/necessary.

You shouldn't "need" to update kernel. Many kernels available do have some improvements over the stock in regards to lower voltage for better battery performance, ability to over clock, other performance tweaks as well as hdmi stuff. Maybe none of those features will interest you but the option is there, flash a custom kernel and if you don't like it, flash the stock kernel. User experiences vary, you are the best judge of performance.

I was unsure about flashing a kernel for a while, it can be a little intimidating but u won't regret upgrading your Kernel. I eventually moved onto building my own kernel.
If you looking for a good sense kernel I would recommend Lionfish. Freedom and Chop Suey also are good kernels.

[Q] Which root has least Sprint crap, most stable WiMAX, and best battery use??

So far I have tried unrEVOked and AVA-FROYO V10.
unrEVOked is little bit behind on latest kernels and is stuffed with Sprint garbage. It did have great battery life with 4G and WiFi enabled (12 hours for me).
AVA-FROYO V10 was OK, very little Sprint crap... but battery life on it was extremely unpredictable (from 4 hours to 12 with cell standby chewing up most).
Unfortunately the latest radio update messed it up and now I need to reflash everything, so might as well look at other roots.

Do you mean ROM?
WRONG SECTION !
unrEVOked and kernels ? LOL
I am sure they will move it to the right section.
Yeah, you are right, I did mean ROM. Had a massive brain cramp, so I called it a root
Re. unrEVOked, hey, I had to start somewhere
Cyanogen..... soon

I didn't have the best luck with AVA V10, but V9 has incredible battery life. Here is a link:

Whichever ROM you download, you can open the zip (don't extract), go to system>apps and delete any apks you don't want it to install when you flash it. Of course, make sure you know what apks you are removing first so you don't get problems later and have to end up re-downloading/re-flashing your phone.
unrEVOked is not a ROM, nor a kernel, and has nothing to do with battery life. Other than the superuser app showing up, it should not affect anything at all. It's a rooting process, specifically intended to unlock your NAND (S-Off, visible in the bootloader).
Popular ROM options are Fresh, MIUI, CyanogenMod. Fresh has fully working WiMax. CM is close. Don't know about MIUI, but it's probably not packing working 4G. None of them have any of the Sprint apps by default.
You can bake your own Fresh ROM with whatever you want included. CM doesn't even include the Google Apps by default (you can add them easily), so it's even trimmer.
Once you are fully rooted, and familiar with the nandroid backup process (and Titanium Backup), you can switch between ROMs fairly easily and make your own decisions.
To get started, root and then flash Fresh. Actually, wait a few days (but don't accept the current OTA if you haven't already), and install Fresh once it's been updated. Because it's based on stock with Sense, you can probably flash without clearing your data (DO clear your caches) and get off to a quick start.
Yeah, I am still learning this rooting process. I have very little time available for playing around a bit and no way in hell am I going to use time of my devs in the office. Hence me doing it the lazy way - asking you which ROM is the best for my needs and then flashing and forgetting it.
BTW, thanks for the advice so far. Saving me a lot of time!
MYNs is popular or if you want a stock one, I suggest looking at the ReEngineered Stock ROM that aamikam made. He spent alot of time fixing up the apks so that they are smaller in size and speeds up the ROM.
i would just find a rom that you like and run with it. the rom itself shouldn't make THAT much difference. from what i have seen, its your kernel that really makes the difference in batter-life and performance. Most of the bloat-ware in the majority of these roms can be removed pretty easily.
Myn has some great stuff for ROMS. Ava V10 (if you have bad battery, try a different kernel)
Here are my 3 fav Kernels:
Hero's Laptop Kernel (all i have to say is WOW)
Net's 4.2 or 4.1
King's CFS
ROMs:
Sense: Calk's or Myn's or for a pure stock feel try ReEngineered 3.70.651.1.
AOSP: Cyanogen Mod (No Contest)
Kernels:
I always stick with Stock on all the ROMs I have tried.
Have fun flashing man.
Try Azael X its very fast very little no bloat and stable 4G plus battery life is great he will update to 3.70 soon he's working on it now Rick is very picky about letting his roms out with bugs so he tests and tests before release

[Q] kernels

hi, i'm about to flash leedroid v 2 on my desire hd, but i was wondering what the kernels in his site for? do i really need to flash them? and how?
This is what a Kernel does:
http://en.wikipedia.org/wiki/Kernel_(computing)
Or, a short explanation: It's the interface between your Hard- and Software.
The faster and the more optimized it is, the faster, smoother and energy efficient your DHD runs.
If you're on Leedroids ROM you already have one of the best Kernels around.
In this case it only makes sense to flash another Kernel if you want to overclock your device. (And no, I won't describe overclocking, too. If you've clicked the link above, you're already on wikipedia to look that up, too ;-) ).
i think leedroids rom includes his latest kernel anyway, the flashable one is for people not using his roms
Every ROM comes with a kernel. Leedroid 2.0 came with a kernel. Then later Lee added some modifications to his kernel and a new kernel 2.0.1 was made available and so forth until 2.0.4. Since changes were somewhat minor he did not introduce a new ROM version. But this means different people may be using the same LeeDroid ROM each with different kernels and different experiences. For example the latest recommended kernel seems to be 2.0.3 as 2.0.4 has more battery drain.

[Q] Telus friendly Kernel's for CM7

I'd like to start using the custom Kernel's but TMK, the Telus variant has specific requirements.
I started looking through some of the Kernel threads to see if a Telus owner chimed in to either ask or confirm compatibility but found that very tedious.
Do you know which custom DHD kernel's work with both CM7 and Telus?
Thanks.
Since nightly CM7 #22 you havnt needed a kernel. Pretty much any kernel for the Inspire/dhd. Everything's been ironed out i believe
Always nandroid before attempting of course you can always go back
I'm coming from an N1.
There a need for a kernel isn't necessarily warranted but found for example iR's CM-specific kernels to have significant benefits over stock CM.

[Q] Need help picking a kernel

Ok so I am new to the droid Incredible and as you can kind of tell I am coming from the HTC Hero by sprint. I looked around but nothing really helped me making a decision so now I am asking you! I am currently running the newest Synergy ROM which is android 2.3.3 and I haven't seen any gingerbread Kernels, just froyo. What kernel would you recommend for battery life because I am used to having atleast 2 days but I was running cm7 but I missed sense way too much lol
Unfortunately there are no options for custom sense GB kernels aside from what the rom comes with.
ok so that's why I could not find any, is there one in the works though?
That'll be a possibility when the official GB version source code is released, which will be after we would receive the OTA.

Kernal help
I too need help picking a Kernal. I am totally new to this Rom thing but luckly was able to root & get SkyRaider 4.2 running on my Droid Inc. on my first go with no trouble.
So what I'm mainly looking for is to get:
1. Better battery life
2. To overclock cpu
(If you have any other tips for me on getting the most out of my phone, they would be MUCH appreciated.)
So I've been thinking of flashing the Incredikernal 2.632. But I know that this new version of SkyRaider was just updated or released not too long ago. Will this effect my decision? Is the Incredikernal I want even compatible with my current SkyRaider rom? Or should I just stick with what I have? Thanks in advance.
I'd recommended trying incredikernel, you're not gonna hurt anything flashing kernels so there's nothing to lose and you very well may see improvements in performance and battery life. Just make sure you get the incredikernel for sense from 12/23. Other options to look into are heyitslou and ziggys.

[Q] Evo 4G Kernel

I just recently installed a custom ROM and i wanted to overclock my Evo because it was laging a bit but i heard that to overclock your evo you have to have a custom kernel. I have no idea what a kernel even is, lol. I was just wondering if anyone could tell me a good kernel, that i can use to both overclock my fone, and that won't brick it. If it helps im using the Longed Shooter ROM. And just to let you know, im new to this stuff so go just a tadddd bit easy on me

chopsuey, goldenmonkey, poonsense and freedom are the current gingersense kernels meaning they run on android 2. 3. 3 Roms with sense tiamat, savaged-zen are the aosp kernels I know of off hand as I don't run aosp my particular phone doesn't like aosp for some reason after an hr or 2 every aosp Rom bootloops. I personally run The EVO classic v 0. 0. 3 with more freedom v. 9 golden monkey 1. 1 or chopsuey 9. 2. 7 depending on what I need battery performance or hdmi chopsuey 9,. 2. 7 runs hdmi well on my phone aggressive or more freedom give me good batterylife. and goldenmonkey gives me good performance for heavy graphics gaming but sacrifices the batterylife a bit just pick one or more to test download to ur SD and save somewhere ull. remember it go to recovery wipe cache dalvik cache repeat repeat again for good measure flash and test it out give it a few days to settle in b4 deciding to switch it up and if after 3 days or a week u don't like a particular kernel repeat process with ur next choice. I keep all my roms kernels mods and such in folders labeled what they are and for which Rom if thy are mods inside a folder labeled 0.roms,mods,kernels so its the first folder in my recovery to save my volume rocker some abuse scrolling in recovery

what rom did you flash? if it was a aosp rom check out the link in my sig for other aosp roms/kernels. in my thread there is also a link to another thread on how to set up everything
sense rom - sense kernel (chopsuey, freedom, etc)
aosp rom - aosp kernel (tiamot, cm kernel, etc.)
Its really a preference on which ones you like and how your phone reacts
