[Q] Reverting back to stock from franco.kernel

I have a quick question.
I flashed the franco kernel using franco's app, and also made a backup of my stock kernel using the same app before flashing.
If i decide to revert back to stock kernel, all i'll have to do is flash the stock kernel backup, right? It won't mess anything up?

I'm actually getting ready to flash Franco's Rom now, I figured since the kernel is in the boot image, and if I make a backup with TWRP (doing full since I want to keep my latest changes). Then if I don't like it I can just restore only the boot image portion of it assuming everything else remains the same.

Flashing a Custom Kernel

Hi, I have some question about flashing a custom kernel (+Franco kernel):
1. Let's say I have Franco Kernel and a new version comes out, do I need to flash it again or I can use the app to flash it? Also, do I need to wipe something before I flash?
2. If I switch to another kernel from Franco, what exactly do I have to do? Just wipe cache+dalvik and re-flash my rom?
3. Will I have to re-flash the kernel after each rom update?
Thanks!

Hi I'm not sure about #1 because I don't use Franco's app, but 2) Sometimes you can just flash a new kernel over the old one. Personally I prefer to dirty flash my ROM, then flash my choice of kernel. 3) You'll need to flash the kernel after a ROM update. The ROM is compiled with it's own kernel.

So I need to dirty flash my ROM (=wipe cache+dalvik & flash) then install a new kernel? Thanks.
Still need an answer to Q1 though

I use CM 10.1 and just flash the new Franco kernel ZIP over the old one and it's been fine...

1. When a new version comes out all you have to do is flash the new version on top of the old one. You can simply download it from the app and let it do a auto-flash. No need to wipe anything.
2. It depends. Some kernels will need you to flash the stock kernel first then flash the custom kernel you want to you. Ex. Faux kernel. Don't forget to read the first post of every thread to look for installation instructions.
3. Yes, you will need to reflash the kernel after a rom is flashed. Make sure to flash the kernel last.

1. Does the app need a special recovery to work? I have a TWRP recovery..
2. What do you mean by stock kernel? And is it correct that Franco is the only kernel that I need to re-flash my ROM to switch to another kernel because it changes something in the ramdisk? If so, do I just need to do a dirty flash?
Thanks.

1. No special recovery needed. I too use TWRP.
2. Nothing special need be done to flash to Franco. Going from Franco to another kernel it is easiest to reflash your ROM. You are correct about the ramdisk.

2. So going from Franco to another kernel - just dirty flash without a factory reset?
Thank you very much.

1. Having a recovery is good. When you download a new kernel there is an option to let it do a auto-flash and it'll flash it you. The phone will reboot itself when it's done.
2. Some custom kernels need to flash the stock kernel, (the original factory kernel that it's shipped in) if you're going to switch to another custom kernel like Faux's kernel. So when the next time you want to make a switch to another kernel, please make sure to read the first post of the thread to look for instructions to install the kernel. If you're updating to a new rom or switching to a new rom, you will need to flash whichever custom kernel you were using on top of the updated/new rom. When you flash a new rom, it is recommended to do a full wipe to avoid issues. After every rom flash you need to flash the kernel.

No. no. You don't need to do a factory reset. I don't know how many times I'm going to say this but read my answers to all of your questions again. (Don't mean to sound like a jerk or anything)

I think that's what he was saying/asking... That's correct, no need to factory reset.

you have made alterations to your phone so its not longer stock. the file you are flashing is for a stock rom and to be flashed in a stock recovery. to flash the update simply re-flash a stock recovery and allow the update to go through. you can also simply wait and flash an updated custom stock rom.
Edit: link deleted....may confuse you
Edit2: Using the toolkits you should be able to find the stock recovery image and flash it back

[Q] [HELP] I flashed wrong kernel file and now my device don`t boot

So, i was in a hurry and i downloaded the wrong kernel. I wanted to download the linaro franco kernel for android 4.4, but instead i downloaded this one "franco.Kernel-nightly-r14-linaro.zip". this is an old version.
So now, my device does not boot and i cant install the correct kernel file.
What should I do?

Use a toolkit like wug and install through it the stock or any custom kernel you want.

But...
But, there is a way to only replace the kernel or i have to re-install the ROM?
Re-install only the kernel may affected something?
Thanks a lot.

No.
You need to flash the stock boot image to get the stock kernel.
You need to flash the stock ROM to get back to a stock OS.

Ahh ok. Still got oxygen but I flashed Franco was all.

If you want to get rid of the Franco kernel just flash the stock boot image.
You will then have the stock kernel.
