[Q] Can i flash JB (I9300XXELLA) Kernel in a ICS ROM - Galaxy S III Q&A, Help & Troubleshooting

Can i flash stock JB (I9300XXELLA) SDS Fixed Kernel in a ICS Stock ROM?
I just want to install the kernel on my ICS Stock Rom, is it possible or the kernel being JB will cause problems in my ICS System

Why are you still on ICS?
I'm pretty sure you can't flash just the stock kernel without the ROM. Update to JB and flash a custom kernel that has the fix, like perseus

I like the battery duration of ICS, also i ve read lot that JB drains a lot more battery and doesn't last as long.

You can't fix SD on ICS

ICS roms are beta at best, I wouldn't advise flashing one.
There is CM9 which is AOSP and there is Samsung leaks, all need ICS bootloaders, search and read before you even consider flashing any of the ICS roms.
how to get ics bootloader?? will it be automatically there if i flash a ics leaked rom??

Depends on the rom, stock ones will come with ICS bootloaders, you *may* need them first for CM9. Also if you want to go back to gingerbread from ICS you will most than likely need to flash back to the old bootloaders from this thread.

[Q] Can I flash official ICS using CF-Root Kernel?

I already have CF-Root kernel and CyanogenMod 7 on my phone. I'm looking for to flash the official ICS, but should I flash a NEW stock kernel for ICS? Should I go back to my GB stock kernel before doing that? Thanks a lot, guys!

There should be instructions on whatever page you download the ICS you intend to install from... Right? Follow them.
If you will push Android 4.0.3 or other Custom ROM on your current set up, it will over write your entire OS.

You can, but not every kernel supports every Rom. So I suggest make a nandroid and flash the kernel . If you face issues then restore nandroid.
I have tried many kernels on stock Rom , and never had issues till now.....
Yeah it works fine.
I don't know why you would want to stay with stock, because there are rom's like anryl's which is 99% stock, but with slight speed enhancements.

[Q]About custom ROM's based in 4.1.2

Hello,
I've been frequently checking the web for the official JB update and everything i've always have read is that it will be released soon, not OTA yet so I'm going a bit desperated about having JB on my s2. I'm actually on 4.0.4 official (yeah, the brick evil kernel) and I'm pretty happy with it but I'm very curious about all those 4.1.2 custom ROM's roaming around the net.
What's your advice for this ROM's? Are they worthy to install them at this point in my device? Are they fully working with all the JB functions? Or at this point should I wait for the official ROM and give chance the community to work in ROM's based on it?
Greetings, any advice/hint will be much apprecciated.

Fully working now, yes.
Now go out and do some reading so you can take your pick.

Well regardless of what above poster says, no they are not fully working. However the bugs that are present are not serious and most people will not come across them.
However I would HIGHLY recommend that if you flash the leaked stock rom or a custom one based on it you will need to flash Joboo kernel as it fixes the most annoying bug which is the lock screen delay which is really bloody annoying. It also increases battery life as Philz kernel is bad for this. You can also freeze non-needed stock apps to increase life more.
By the way incase you didnt know, since you have 4.0.4 stock you dont need to worry about the brick bug if you simply flash a custom kernel like Siyah instead of keeping stock.
Okay, they are not fully working I guess. I can always be wrong.
Still, reading time.

Yeah, actually I did know that I could flash Siyah to avoid the brick risk but I just wanted to do it all at the same time, I mean, root -> flash Siyah ->jump to another custom ROM. That's why my question about waiting for stock 4.1.2 for more stable ROM's before flashing and rooting :victory:

You dont need to "root" and then flash Siyah, Siyah gives you root.
If coming from stock rom/kernel all you need to do is....
Flashing custom rom:
Flash Siyah kernel via ODIN
Reboot into custom recovery
Wipe data/factory reset
Flash rom zip (and gapps if using CM based rom)
Reboot device.
Note that flashing a custom rom will come with its own kernel so it replaces Siyah.
Flashing Stock Rom:
Flash stock rom via ODIN
Flash compatible custom kernel
Note: If you using leaked JB you should use nothing but the Joboo kernel. If flashing GB or ICS rom you should use Siyah.

[Q] (Xgo) Cm9 or Stock

I was just wondering whether i should use munjeni's stock rom with oc kernel, or is the cm9 rom by fxp is worth it. Has anyone tried both and if so which gives better performance.
About CM9 and the .54

In my Opinion the Stock ROM ICS: a burden, seems like a just out of the 'beta' rom.
The CM, something is bothering me and I didn't found the thread about the Stock ROM b.54 ... Why do we have to have this ROM instead of the c.10 ??
Seems illogical for me regarding the baseband modem.
So if you find the answer to the b.54, please share it.
About you doubt bet on CM.
Regards.
There is no need for overclocking the cpu. I use CM9.1 on my Go and it runs very nice.
@lvcargnini the .54 ROM updates your modem firmware

ok, So it is done.
Running CM9 now, and it is really nice and neat this FXP203, of course this LED bar is annoying me.
