[Q] Should I update my kernel?

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.

EL29-FE22

Hello everyone. It's been over a year since I rooted and flashed custom roms on my phone. So please excuse me for my question. So I rooted and installed Clockwork/TeamRogue with the help of ACS's youtube video. I see a lot of people on FE22, I am on EL29 and I am using The Blu Kuban's ICS rom. Is there is a difference having FE22 vs EL29?

Welcome back to flashing. First, a couple of things: As soon as you flashed the Blu Kuban your kernel was changed to the one that the ROM comes with. EL29 is the stock kernel that came with your phone (and is a Gingerbread kernel). I believe you are now using Calk's FD26 Repack kernel (an ICS kernel). Under 'About Phone' in your System settings it will tell you the kernel version you are using.
Unfortunately, EL29-FE22 are also numbers for modems. So you are probably still using the EL29 modem and the FD26 kernel. The Blu Kuban has an awesome ROM Updater in the System settings and contains all the different kernels and modems that you can use with the ROM. Just be sure to use safe flashing techniques as the E4GT is still very susceptible to being bricked.
And don't forget to follow the Blu Kuban development thread, there is a wealth of information in there.

Is it possible he's running the Blu Kuban GB ROM (hence the reference to EL29 unless he's talking modem) http://forum.xda-developers.com/showthread.php?t=1449023 as opposed to the Blu Kuban ICS ROM? http://forum.xda-developers.com/showthread.php?t=1625535
The main difference between EL29 and FE22 is that one (EL29) is Gingerbread while the other (FE22) is ICS.
Read up big time before making the leap to avoid any nasty bricks.

thank you for your help

strange. I went to the development section and installed the ICS version and used the FD26. I will make sure to readup

Good idea and enjoy, it's a fantastic ROM.

So I decided to try Cyan 9 and followed the instruction including adding EL 26 as it says in the instructions but it still shows EL29. If I decide to go back to Blu Kuban can I just use rom updater and flash the FE22 modem?

som roms come with kernels some without but most roms dont come with modems they leave it up to the flasher to flash modem seperately. blue kuban makes it ez by making it all available within the rom updater options for reduced bricking risk.

All roms come with kernels. They wouldn't boot if they didn't. I think you meant to say custom recovery.

Flashing Ics roms

Hi guys I'm new to the epic touch and was wondering if it is safe to flash a Ff11 from an already installed ff11 rom and how or is it necessary to restore to gingerbread before flashing the new ff11 rom. Lastly, what is the most stable ICS ROM with everything working? I tried AOKP and it had messed up video recording and bad wake up lag. Thank You

Yes it should be safe but just do yourself a favor and only flash, back, restore, wipe, etc from el26 cwm kernel/recovery. Most stable ICS rom would probably be just a stock leak or maybe calks 1.6 rom. I personally use CM9 and its good.

Thanks I did just that. A question though, why do the rooms have wake up lag... Is there a way to fix this?

Personally I wouldn't take the chance with the emmc bug. It takes like2 minutes longer but I ALWAYS flash back to el26. Just not worth chancing a brick.

All ics roms are still leaks. Some devs have been working on tweaks but no source yet to work from. Soon we hope.

I flash from EL29 there is no difference in flashing from EL26 or EL29. I have been using team venom's roms and they work great and really could be an over the air with absoultly no bugs what so ever. I use my phone fro work all day long 5 days a week and havent had the first minutes trouble.

I have flashed Multiple ROMS, and if your looking for batter life, the any ROM from Mijjz of Team Venum is definitely what you want they are all stabil. I am currently using "Mijjz Blend ICS " No Name" ROM. the Xplod Mini rom runs on a sony based kernel and works well, so if you want a differnt interface its a great choice while still keeping the battery life. Blu Kuban Rom is great if you want a variety of optional tweaks built into the ROM. There is a new Team on here called Team Rejectz they just released a new ROM that looks great, I'll be flashing that this morning, and Give you guys an update on how that turns out. I always flash back to either EL29 or EL26 before flashing a new ICS Rom.

Same here I have been using cm9 as my daily driver for the passed couple weeks and it is rock solid stable! Love ICS I cant imagine going back to Gingerbread after the ICS experience. Its alot faster, way nicer and just overall smashes gingerbread. Lol Not like IOS5-IOS6 where ya get 1 or 2 new features.. Features that Android have had since froyo..lool!

Current Best ICS Rom?

Hey all,
Finally about to make the jump from GB (on Calk's 3.0) to ICS. I need a Rom that is stable (daily driver status) and wanted to see what thoughts you all had. I've been reading all the threads for weeks and think Phantom's Blazer might be the way to go. I'm also considering just using odin to install the stock (and rooted) stock FF18 as my signal is horrible and not sure why (tried many modems). Anyway all thoughts welcome... CM9, AKOP, re-Calked....
May have to try them all!
Thanks!

CM9 all the way. Getting great battery life, its typical for me to go 12 hours right now with moderate use (texting, phone calls,web browsing and flipboard) and still be at 50% battery. This rom is so customizable with the notification shade and tethering it should just come with it CM9 out of the box. I was a little worried with the stability of this rom but I haven't had any issues at all. 4G, Camera and GPS is great too. Its snappy quick responsive. Going from stock to CM9 will feel like its a new phone and until we get LTE for Sprint in Minneapolis I'm sticking with this great phone

blazer 1.5 has been remarkable in smoothness and speed and I installed agat. 4.2 and ff18 modem

If you want to stay on caukulins roms there is a recalked 1.7 out for ICS.

Blu Kuban is fantastic and stable as well as Milestone 6 and make sure you update your modem if you make the jump. Using Milestone 6 with fg20 modem and loving my phone

seriously
I'm on CM9. It's relatively stable as a daily driver and my battery life's been getting much better. It was horrible for about a week after flashing. CM9 and AOKP are pretty interchangeable, but I think I like AOKP more. Keep in mind, they're still alpha, so bugs will happen, but I don't know why alpha 6 wasn't just made beta1 as planned. From my understanding, the ICS FF18 official source needs to be un-f*cked before CM9 goes official, so I'm holding my breath. Meanwhile, I'm interested in CM10. JB is supposed to be better than ICS in many ways. Going from GB to ICS, you are probably going to be let down unless you choose a rom wisely.
If you love Calk, like everyone does, it really might be worth trying the RE-CALKED 0.1.7. I'm debating flashing it now, but I want to know more people's opinions about it first.
So, rest of this forum, how does RE-CALKED 0.1.7 compare to CM9?

Hey everyone, thanks so much for the replies. This is REALLY helpful. I'm really excited to get started on flashing! I think I'll give CM9 a shot first but may try a few others.

Thanks, glad you mentioned this. I was actually wondering, given all the issues with ICS and bricking. In the "how not to brick your phone" thread it states not to restore GB while it ICS. Does this refer to nandroid backup/restore? If so, then I would suppose that you need to first oden back to EL26 or ED 29 then restore, correct?

I was on gb a couple days ago and restored my ics back up.. All I did was flash a Calkuins wipe all script (if you don't have it I can link you one) restored my ics back up & then flashed agats source kernel to get it to boot.( http://forum.xda-developers.com/showthread.php?t=1767421)
You're good as long as you use a wipe all script and agats source kernel (they say you can wipe data in agats new source kernel but I haven't yet.. I just always use the wipe all script just by habit Plus it saves me time to have to manually wipe everything)

Just to go on top of that. I have/do wipe data manually in agats recovery. No issues so its available/safe if you want to.

How do i use a rom with any kernel?

Hey all, i've been running through ROMs here going back and fourth trying to find the best one for me. And so far i love a couple of ROMS, but the only ROM where i get data speeds that are good is Snipers Lightweight ROM using EL29 modem and agats fl27 repack kernel. I want to be able to use this Kernel and modem on other ROMS (the blu kuban for instance), but it seems most of ROMs require a certain kernel. Is there anyway around this? so i can use whatever kernel i want on any ROM?

I don't think so. As you know, a kernel is like the base and the bridge between hardware( CPU,etc...) and apps. So if the rom isn't made for a specific kernel, the phone won't boot up

Yes you should be fine. The aroma installer included in Lightweight even has several different kernels to pick from, as they're all for ICS TouchWiz (like Blue Kuban ROM).
Now, if you're using a repack (like fi27), you won't have all the extra tweaking/over/underclocking options like you would from a custom source-built one. But if all you really care about is data speed then there should be no problem.
