[Q] flash new rom from another - Nexus 5 Q&A, Help & Troubleshooting

I'm using catacylsm rom+franco kernel
If I want to flash another rom, do I need to flash back to catacylsm's kernel and flash the new rom?
Thanks!

Hi,
No, no need to flash back the stock kernel before (or the one from Cataclysm rom). Since you'll flash another rom you do a full wipe (clean flash), it will be enough.

Flashing

So I've been flashing various roms, kernels, and radios onto my Nexus S since the release. I've never read to deeply into the exact procedure for flashing these items.
I know you are suppose to wipe device, cache, davik, ect. But then are you suppose to flash the rom, reboot the device, and then flash the kernel and radio?
What if you wiped the device and just flashed a rom without a kernel? Does the kernel you have previously take into effect or is it built into the rom?
No, Roms come with a kernel. If you don't flash a kernel you will have whatever kernel the developer uses in his/her Rom.

Wha? Not all ROM's come with kernels... if you flash one that does not have a kernel then you will be left with what you had before (stock).

[Q] OTA on stock rom and trinity kernel

This is my 1st time on this forum!! be gentle!
I have stock rom and trinity kernel, can i get OTA working?
you won't be able to install it regularly because you changed the kernel, but you can always flash a full 2.3.6 rom through cwm. i'm pretty sure you'll be put back on stock kernel though

youll need a completely stock /system and the stock recovery.
Thx for the help!
Just flash the rooted version and you are done.

Flash stock kernel without Rom?

Is it possible for me just to flash stock kernel instead of the whole stock Rom ? If so is it available here ?

extract the boot.img from a stock rom and flash it via the terminal emulator app or via fastboot. theres always the chance that the stock kernel wont run on whatever rom that youre using. if so, just reflash the rom.
I've got a link to a stock kernel somewhere, which you can flash via cwm recovery. I'll see if i can dig it up.

[Q] Little help installing rom

Atm i have elementalx kernel installed and thinking about switching to franco when i install a new rom. I am on stock rom and will probably flash to Slimkat, will i just have to flash Rom + google apps and then elementalx/franco?
Read the op for slim. If it says to flash gapps then you'll need to do that. Then flash the kernel
