Kernal ??

Is it necessary to flash a Kernal after flashing a custom rom ?
I am thinking of flashing CM 9 or Liquid Rom. Which is the best kernal to flash with them.

-The correct spelling is kernel.
-It is not necessary to flash a new kernel with a rom. In general roms will package the stock kernel unless they note otherwise.
-I am personally a fan of leankernel because of the mission statement behind its development and the accessibility and speed of its update cycle.

Nope. Custom roms have kernels included, so you are not required to download a separate kernel. However, some kernels run better (ie, more fluid, less heat, reboots, etc) than others on the same device. It all depends on the silicon in your phone. If you plan to run cm9, I recommend sticking with the default kernel. If you're going with Liquid, use imoseyon's leankernel (the default) or franco kernels.
Edit: BTW, I highly recommend franco's kernel app, especially if you are new to the scene. It can download & install either franco or imoseyon kernels, making kernel flashing stupid easy. It also lets you overclock & undervolt, change governors and tweak color settings. And it is the easiest way to keep up with nightly/experimental builds. Not to mention it shows your support and encourages more development.

i say try them all, but for cm9 i recommend fugumod.

Thanks you all for your suggestions ...
finally going to try Liquid Smooth 1.25 (http://forum.xda-developers.com/showthread.php?t=1555667)
along with Franco.Kernel (http://forum.xda-developers.com/showthread.php?t=1367341)
...... One last question Which Franco Kernel to flash there are Milestone 2, Milestone 1, Nightly ??? Whats the difference between them ?

Also when installing extras for liquid smooth do i need to wipe everything again .. I am new to this flashing stuff
and does Liquid Smooth comes with a kernel if so which one ?

Latest milestone is the most stable. Nightlies are experimental. And no need to wipe.

Liquid + franco is a great choice. Liquid is an extremely polished rom. Very, very smooth with absolutely ZERO lag (it is called Liquid Smooth for a reason) and lots of customization & tweaking options. franco kernel pushes the smoothness to another level. Liquid & franco are both awesome devs who have been tinkering with android for a long time, and they both know their stuff.
Liquid comes with imoseyon's leankernel, which is a solid kernel (obviously, or Liquid wouldn't have included it in the rom). imoseyon is another well-known & respected dev that churns kernels at a dizzying rate. He must develop in his sleep. A lot of people prefer his leankernel, and you really can't go wrong with it. But like I said before, it really depends on your device. Your phone picks the kernel, not you. Milestones are the most stable versions. Nightlies are bleeding edge experimentals with the latest patches & tweaks that may or may not improve battery or performance. Since you are new to flashing, you might want to go with milestone 2 for a few days and see how it feels. On the other hand, you could jump in balls deep and go with the latest nightly/experimental
And you don't need to wipe anything before flashing the extras package.

doesn't matter,
infact if you flash yakju then you will get OTA as well. if you are in japan you can flash a japan radio on top of the rom.

Kernal?
I have been researching the many different kernels out there all day. I have been running GummyNex ROM's since I rooted my GNex. I really do like the options he has. I forget which version, but the battery life was amazing (which included the baked in kernel). I flashed to .0.9 and recently 4.0.4 1.0.1 and the battery life is like a V-12 Lamborghini. I just flashed a Franco Kernal and am hoping this fixes my battery drain issues.
Something has to give......

Use liquid rom with Franco milestone built ... gave me a 4+ hour screen time. Don't know why but the nightly version reduces battery life
Sent from my Galaxy Nexus using XDA

I'm running Liquid 1.3 and am using Franco nightly #143 and, so far, my battery life is really great. I was at 89% after 2 hours. I also want to try Milestone 3, that just came out yesterday and see how it performs.

[Q] How to speed up ICS on R800i?

Currently running the latest version of Dark Forest ROM and a slightly too old version of DoomKernel.
I notice that there is some serious performance drops with ICS. Any suggestions on getting this back up to speed? Better ROM to use?
Also, off topic, I haven't been able to find a link to a version of the Beta ROM with WiFi, data, etc enabled and NO OTHER CHANGES. A link would be helpful and I have searched.
Thanks in advance for both requests!

CM9 based roms seem to be the smoothest - AOKP is the best for me. You can try overclocking on darkforest rom and updating your kernel may help alot as well.

Thanks! Been meaning to update the kernel but I guess I'm just lazy. I'll get that done and try your other suggestions later but for now I've got a pile of coursework to do. Already overlocked to 1.4 Ghz but I guess the old kernel may be holding me back. Also is there a CM9 available for R800i that supports the gamepads?
Cheers again!

Touchpads do work in all cm9 roms but they're app specific - some apps allow them to work and some do not, it depends on how the app developer implemented them or so I've read.

[Q] So I rooted my phone, now what?

Hello again guys,
I sucessfully rooted my phone but now I have a problem. I have read through alot of forums and sites and I guess the next logical step is to get a new rom and kernel. Now I have done alot of reading about all this but I'm getting quite confused between the pair. From my understanding the kernel controls all the complex stuff like making your phone run faster/slower and increasing/decreasing battery life.... I'm stumped at what a rom is,it's like, the operating system but custom ones are more streamlined?
So what I'm asking for is a little information and some suggestions of what I should put onto my phone, I read something about a smartassv2 which is supposed to keep the phone more balanced, now im sure if it is a kernel or a governor?
Any help would be apprciated.

Have you put cwm or different recovery on your phone yet. Also do you have the CDMA or gsm version

Yeah, the utility I used to root it also installed cwm, I checked it out and did a backup which should be on my SD card now.
beleive it's gsm, it has a sim card and is on T-mobile.

Ive just installed link2sd and partitioned my sd card, was able to move over a game that I couldnt originally get over to the sd card, saving a bit of space.
Also with link2sd I was able to delete preinstalled bloat like twitter, friendstream, news, weather, stocks, etc.
So far a good day

smartassv2 is governer you can use cfq scheduler with it.
about suggestions:
after rooting you have two options:
use cyanogenmod roms:
cm9.1/cm10
(original modpunk cm9.1 ,speed droid,jelly king,miui etc)
use stock sense roms:
(wildchild etc,sense 3.5 etc)
these all are main roms after there are many variations like pacman rom,aokp build cm9 but they are not much stable at this time so.

Sorry to be a pain can you give me a little info about the listed roms? You put cm9.1/cm10 then the others in brackets, are they just like the same roms but with slight differences or is cynaogenmod a kinda name for those type of roms?
EDIT: Just looked up CyanogenMod.org, doesnt show that it supports HTC Wildfire S.

ps there are many other roms based on cm10 like pacman,miui and also slimroms ,paranoid(its tablet ui rom you can change dpi of any app widget its benefit of this rom)
but i havent tried them but you can.

Personal oppinion
When I rooted my wildfire s I was exactly like you. I started wondering what I should do or where I could find it.
After testing a few roms I will tell you what worked for me: Test different roms till you find the one that suits you.
Anyway, I'll tell you my advice:
- WildJOY joyOS First rom I tested. No bugs found.
- Modpunk's CM10 As far as I've read the rom every one uses as the base for their own ones.
- JellyKing This is the one I'm using right now. Active development and really smooth.

Jelly King V2.0
I flashed my phone with Jelly King V2.0 4 days back. Its working very smoothly.
You get 69 MB of internal space to install things.
Panorma mode in camera etc. Try it. you'll love it.

I was v.happy with v1.3 dedoxed i had no problem with it till yesterday started to have problem with viber ''NO SOUND'' , skype signing out when i try to make a skype phone call.. i tried to many things re-flashing the Room without wiping data factory sittings No backup lool so today i flashed the V2.0 with full wipe but its kinda lagy!! not smooth like the older one !! Kantry 123 made amazing job i really appreciate his hard work :good:

I don't find it that laggy as you say. Maybe it's because i don't spect too much from my little device. If i were you i'd try the kernel to test if it goes smoother or not.

[Q] lupus v10 with stock 587 rom

Hi
I have a question for what I did not find a straightforward answer;
Some back story: I have an Xperia Arc S with stock .587 rom, I wanted to unlock it so I payed on a site to unlock it with point test {if this is the correct way to say it}, the simlock was removed 'yaay' and they also unlocked the bootloader. so a few days back I wanted to play around with kernels and roms, tried lupus with xperia hd 3.0.2, I didn't like it, don't ask why, and I wanted to return to stock, I messed up, soft bricked the phone...long story short, today I resolved the problem and I managed to install the stock rom again.
TL;DR; Can you use the Arc S stock rom with Lupus v10 kernel ? and does anybody have any experience with it ? worth ?
Thank you
If you have any other kernel suggestion that would come in handy too :fingers-crossed:
Greetings from Hungary.

As an old Arc S user, I'll tell from my own experiences..
Using Lupus or any custom made kernels that are made with the purpose to give you overclock options and alternative CPU Governors on stock & non-rooted ROM.. It isn't worth it, because you will not see any difference in performance.
Tweak and debloat .587 ROM in case you are going to use Lupus kernel, I am saying.

Sound interesting, I mean I don't really care about performance, that much, the only thing that I noticed with Lupus kernel {or I guess whatever kernel} is the battery life increase.
I'm still thinking and searching the forum to find a good answer, I have no problem with the stock kernel + rom, but if a custom kernel would give the same performance + better battery life that would definitely help
ps I have no idea how to tweak and debloat[ i don't even know what that is] :silly:

Well, battery life can increase if you are using the right CPU governor and I/O Schelduer (spelling?).
But the increase in your prefered option (BATTERY LIFE) isn't that big on an extended functionality custom kernel, I think, on stock & bloatwared ROM. It can be even worse.. Some battery tweaks in build.prop and some init.d power saving tweaks / scripts can help perhaps.
Best is to try it yourself! Be aware of partial wakelocks, Sony got some bad behaviour with applications that wakes up your Arc S..

Others seem to be having no problems. Perhaps its something to do with gapps. I'm assuming you used full gapps. Try the mini or light version of gapps. So long as u done your full wipes I can't see any other reason. Maybe try flash ROM let it boot then go back to recovery and flash gapps.
Edit - OK so apparently light gapps just causes FC'ing I'll link to other gapps when I'm home.

i flashed this ROM with full Gapps in Xperia Arc S, and it's working really fine, until now had twice random reboots, but that's not really a problem to me.
other than that the ROM is awesome. :good:

Hi,
May I also post on the Pro version here? There is no seperate thread for it.
It's my first attempt on a custom rom after using stock ICS. Unfortunately, I found it to be very unstable
My first attempt was Lupus/v21, now I'm on Fusion/v22. Both seem to be highly unstable. Just using apps is normally fine, but a few things seem to provoke lockups including unlocking the screen, listening to music and using the camera.
I did a full wipe before installing (system, cache, dalvik cache, data), I even tried the permissions fix.
Otherwise it seems a great rom, perfect feature set and very fast, but the unstability makes it unusable for me

Yes u can post here also. Comparing any 4.2 ROM to STOCK ICS, stock ICS would be the winner in terms of stability. 4.1 is the best if you want JB IMO. But 4.2 and especially PAC 4.2 has a lot more features, customization amongst other things. It doesn't matter on the kernel its going to be the same. This is why FXP stopped developing after CM10 for the XPERIA 2011 line-up. It will never be 100% stable as will any 4.2 ROM for Xperia 2011.

I don't know what calls you stabillity, but 4.1 is very stable, almost as 4.0. 4.2 isn't stable specially with 3.x kernels, but 4.1 is perfect. And FXP stop the development for 2011 line becase they have to develop for a lot of devices, i think.

I said 4.1 is stable. And no they stopped because without a stable 3.x kernel it would be impossible for a stable 4.2 J. There was no 3.x kernel for 2011 device back then, but even still they knew if there was a 3.x kernel it would need a lot of work to get stable, if it even can.
