[Q] How to flash different rom with other kernel? - Galaxy S 4 Q&A, Help & Troubleshooting

I'm currently using the i9505 GE ROM but it's causing lots of problems (random reboots, can't make phone calls) so since I am new to custom ROMs I don't know how to safely flash another rom if the one I am using now is using a different kernel. Help

For each rom has instructions on how to install

These are really basic question. You should already have know the awnser for it, before you started flashing.
Forget about kernels etc for a while. It's not important for you.
Just fully wipe and flash the rom you want with the custom recovery.

I know it's basic but I don't know where to find the answers.
So is it safe to flash the stock rom while i'm on a GE faux123 kernel?

Yes you are mixing things up.
A kernel has nothing to do with flashing roms. It doesn't matter on what kernel you are in order to flash.
So forget about kernels, it's not important for you.

[Q] Flashing kernel issue

I recently rooted my nexus 7 and now im trying to flash clemsyn's kernel to it, however i haven't been able to get it to work. I've tried rebooting into recovery and wiping the cache and dalvic cache, then installing from zip, but it always fails. any idea why?
You flashed it on which rom? I think it's not compatible with your rom.
Ensure you read the OP of the thread to verify that the kernel is compatible with the version of Android that you're using. Remember, always RTFM, even if you think you know what you're doing.
Do you have to flash a ROM before you flash a kernel?

Roms include a kernel and will overwrite the previously installed kernel. If you want to flash a custom kernel in conjunction with a rom, you always flash the kernel after the rom.
Oh! That makes sense. I'll try that later and see if it works

Android 4.2.2 - Settings -> Security error

Good afternoon.
I am using 4.2.2 in my LG Nexus 4. It is rooted with SuperSU and I am using Franco kernel.
Every time I try to enter in Settings -> Security I receive an error. I already tried go back to the default kernel, installed the Clockworkmod recovery and wiped the Dalvik cache and the error continues.
I don't know if there is anyway to export this error report, so here goes the screenshots:
Thank you!
Assertion issues, what rom are you using?
It is not really recommended to flash a custom kernel on the stock rom.

The stock rom only works well with the stock kernel for multiple reasons, I cannot get into detail why custom kernels can be bad for stock ROMS.
I maybe can get to detail if you want me to.

What???
I am running stock ROM with a custom kernel (Franco), as are many others, and it's fine.
A custom kernel is usually just the stock kernel with some modifications (could be a tiny change or something bigger). What's wrong with that?

Its the first time I've seen someone say custom kernels aren't recommended for stock rom. So just curious to find out why that is the case.

It can go well but sometimes something can go wrong so I am saying that it really depends on anything on the device.

Some custom kernels can cause issue on the stock ROM while others has no issues.

Sorry but this doesn't make any sense. Any app, ROM, kernel or whatever could have "issues", it's the same with any software.
Earlier you said that custom kernels shouldn't be used on the stock ROM and that's just nonsense which you don't seem able to justify. What's so special about the stock ROM which makes it less suitable than a custom ROM?
If a custom kernel has been designed purely for a particular custom ROM then maybe that one shouldn't be used on a stock ROM, but you seem to be drastically over-generalising. Most custom kernels are designed for any ROM on the N4, particularly since most custom ROMs are built on exactly the same AOSP base.

Flashing a kernel

I'm new to the Nexus 4 but not new to flashing custom roms etc.
I've just flashed a new rom and want to flash a different kernel over it. Do I need to do any wipes at all? Or can I just flash straight over it?

just flash over, no matter what anyone says. wiping anything has nothing to do with kernels.

Custom Rom Suggestions

Hi All
Does anyone know if an app like Safestrap exists for the Note 3 SM-N9005??
In the original thread it mentions its only for Verizon phones??
The reason i ask is there are so many custom roms and i'd like to find out which out suits me the best (without having to fully test and flash 10 different roms).
Other than that, what custom roms are you guys using at present??
Bobcat, X-note and Omega seems popular at the moment
Phone facts:
Knox at 0x1
Phone on MJ7
Recovery is CWM
Based in the uk
Thanks all

I'm on crash rom I've tried them all
All good roms crash and omega are almost stock and the others are themed
@jaythenut
Brilliant, wondered why there was so many roms but most of them all do the same thing!!!
I've read up on Omega but never heard of Crash, will look in to in now.
How did you choose which rom was the best for you?? Did you flash each one individually?? That must have been so time consuming!!

Thanks for your recommendation.
Im going to flash the crash aroma now and see how it goes
Also i hope Hashcode modifies SS so all users can use this great program

Would a factory reset increase performance and battery life?

Hello guys. I have a Galaxy S4 (TouchWiz Lollipop 5.0.1) that is rooted with KingRoot (I replaced KingRoot with SuperSU anyway), has a stock ROM, a custom kernel and TWRP recovery. I did install a custom kernel because I wanted to improve the performance and the battery life, but I noticed that even with tweaking settings a bit in STweaks , my battery life and overall performance hasn't improved. Especially the battery, it drains so fast.
My kernel is an Imperium Kernel (https://forum.xda-developers.com/galaxy-s4/i9505-develop/kernel-imperium-ll-kernel-v1-0-t3058867). I chose this one because it works well with stock ROM.
What I'm thinking is that I've been updating my phone from KitKat 4.2 but I've never wiped cache or factory reset anything, so maybe some "incompatibility" is causing this bad performance and battery drain?
If I wanted to factory reset my phone now from the TRWP recovery (without touching /system of course), would it cause incompatibility with the stock ROM and the custom kernel? And would it somehow help me improve my phone performance and battery duration?
Don't think so.
A custom ROM would make a true difference to general performance, but battery life may vary.
I found this ROM made by the same dev who made the kernel.
If I flash this, will it erase my current kernel?

It's still TouchWiz. TouchWiz is not known for its performance, that's why many people choose AOSP or Lineage.
@Pwnycorn , could u help me?
First of all sorry that I asked a question here but I had to do this as I wasn't answered in my thread.
I flashed a custom Kernel and now I've lost my network signals. Although my phone detects sim card as I can see contacts but I'm unable to make call? When I installed stock rom nothing happened. I tried restoring boot.img with no luck as every time my phone doesn't even boot after restoring boot.img.

Then reflash your current ROM.

No sorry I mean if I flash a JB stock kernel to my KK rom, would it cause problems?
Sorry but I've got no idea about kernels.

Of course it would! They are for different Android versions; it's like trying to put a cube into a triangle shaped hole.
