I just installed a new kernel, and it caused a boot loop. How can I go back to my old stock kernel without using the RUU, because if use that, i'll lose my root :/
Did you clear your cache and dalvik cache before installing ?
No, was i supposed to? :/ sorry if i missed directions, i was pretty careless about this.

Yes. Always or you will get FC's and have to Factory Wipe and lose your data. If you have a nand backup, restore it prior to the kernal. ALWAYS backup before installing a kernal. Also they say use Amon RA Recovery. I guess ClockworkMod does not wipe the Dalvik Cache and Cache properly.
Make sure you read stuff over and over when it involves rooting, flashing a radio and kernel. I used the ClockworkMod to wipe the cache and dalvik cache and installed the Kernel and it disabled my usb and sdcard. That is not fun trying to get back working. Make sure you do that.
What do I have to do in order to flash franco's kernel coming from STOCK other than wiping cache and dalvik cache?? I already have franco running on stock do I just flash CM wipe both caches boot into CM go back into recovery and then flash Franco and wipe both caches again?? Any help is MUCH appreciated Sorry for the noob question I am still learning

Stock being stock Google?
Wipe data/factory reset,
Flash CM10,
Flash Franco.
Skip wiping caches altogether, no need to reboot in between flashing the ROM and the kernel.
If cm is already installed, you don't need to wipe anything if it's just the kernel. Just make sure you always have a recent nandroid

dont have to wipe anything, just flash it over.
note that when you flash a new nightly of cm, you will need to reflash the kernel.
Is there a list of supported devices somewhere so I can check to see if my LG E975 is supported?
Thanks!

When flashing to a new kernel, do I need to write my device or can I just flash from where I am? Currently I'm on matr1x kernel and I want to go to Franko's kernel. I was planning on wiping the dalvik cache but not factory reset. I'd rather not lose all my apps and settings if I can help it. Any ideas?

Just wipe cache and dalvik and your set to go!

You don't need to factory reset when flashing kernels just wipe cache and dalvik and you'll be fine. Note it might take a little longer to boot because it will be building up cache since you just wiped it.
No need to wipe anything. No cache or dalvik needed either. You just flash and boot!
BUT! When you are using a custom kernel that uses custom ramdisk (ex. Franco), you need to flash the kernel from your ROM first. (I usually just backup only my boot image in TWRP so I can go back and forth between kernels) If you don't, the phone might not boot (will boot to bootloader, which in that case, you can fix the problem)
Also, make sure that you don't overclock too much and expect bugs from nightly releases (a lot of kernels are in nightly version right now, but Franco seems to reach milestone soon). You might not experience any bugs, but you never know.
you should be able to do that
if it is just a zip, you should be able to flash it right across in the recovery.
I just did that an hour ago, it kept everything except the kernel.

This is my first android phone and therefore cm10.1 is the first ROM I've ever had so I've never updated my ROM before. Goo manager sent me a notification saying that Cm10.1 rc2 is now available but in order to download it do I have to wipe my phone to factory default or can I just install it over my old cm10.1 and keep my apps and stuff?? Thanks

The whole point of the CM updater is that you don't have to wipe anything - not data, not cache. Just start the download, click OK to install when it finishes downloading, and it'll flash itself over your previous installation. The same applies to downgrading to an earlier release - no wipe needed.
Yes, you can keep your apps and system settings. No need to backup and restore - they'll be exactly the way they were before you downloaded the update.
However, if you are migrating to an entirely different ROM (i.e. not the official CM), then yes, you probably need to wipe. Going back and forth between different updates of the same ROM doesn't need wiping though.
You can just flash it normally using CWM. It's called Dirty Flashing. DO clear Cache and Dalvik before flashing

So what do I do just download the ROM and its gapps again and flash them both? Which one first?

Wipe Cache and Dalvik -> Flash ROM -> Flash GApps -> Reboot.
And don't forget custom kernels

No need to flash Gapps again on CM, unless data is wiped because of the b/u scripts.
The updater script in the ROM also wipes the Dalvik for you.

Actually you don't have to do any of that except flash the rom and reboot. All the rest is automatic.
I reverted to my backup that I made before flashing. Franco kernel didn't work and I had all the crappy apps I uninstalled from cm10.1 like Apollo and stuff .. What's new is rc2 anyways?
updating cm10.1
Hi all
I am currently using cmw6.0.2.3 and rom cm10.1.20130411-EXPERIMENTAL-p3100-M3 and would like to switch to using cm10.1 nightly. Reason to switch is because pie control in M3 is not working and I saw in some video that it is working in nightly. May i know how to update usingmanual mode please? And also will it deketenall my installed apps and data?
Thanking you all in advance
People,
1) Nandroid Backup.
2) Dirty Flash, if something doesn't work or it starts to fails, restore nandroid, backup everything (needed) with Titanium backup or similar, wipe everything, flash, restore, win.
I have a Nexus 4.
To flash a kernel all I need to do is to go to recovery mode,
Install zip from sd card,
Choose zip from SD card,
Pick the kernel's zip file,
Press yes and reboot the system?
Don't I need to wipe anything like when flashing a new rom?
And should I flash the kernel and then the ROM and GApps,
Or flash the ROM and GApps and then flash the kernel?
If my device acts weird after I flashed the kernel,
And I did a nandroid backup before that (I backed up with a ROM and stock kernel),
After I restore it, will everything be like what it was before I flashed the kernel (Will I have to flash the ROM again?)
Thank you in advance guys!
Yes thats how you install a kernel. Some people say to wipe cache and dalvik after installing, but its up to you.
Flash rom, gapps, then kernel.
When you restore the nandroid it will restore everything, including the rom and kernel that were installed at the time of taking the backup.
So yes...if stuff starts acting up, and you restore your nandroid that you took while on stock rom/kernel it should fix the issues. You dont have to flash the rom again...its included in the nandroid.

What will be different if I'll wipe cache and dalvik or not?

Not 100% sure, but f you wipe them your dalvik will be rebuilt on the next boot, and your cache will also be rebuilt once the system actually boots.
Theres no harm in wiping them.

you never have to wipe anything when flashing a kernel, nothing, regardless of what others say. the dalvik nor the cache have anything to do with kernels. its like taking a shower and washing your socks to put gas into your car.

And two last questions,
How do I update a ROM?
Should I delete the zip files of previous Roms and kernels and keep only what I'm using (let's say PA 3.60 and Trinity/Franco kernels)?

if you want, keep the current rom/kernel and the previous. thats probably the smartest way, in case one is buggy. but, at least, keep a copy of the current rom/kernel in your storage at all times, itll save you headaches later.
when you update a rom, flash it in your custom recovery. flash the rom, gapps if needed, and the kernel, the reboot. if youre just updating, you dont have to wipe anything. but if you are flashing a new rom, you do have to wipe data/factory reset.
