[Q] Bootloop on any rom, after wiping cache, data, etc.

Hi,
Last night my I9300 decided to randomly reboot and get stuck in a bootloop. This morning I took the time to wipe my cache, data, etc. through CWM but it still would not boot. I did a wipe data/factory reset, wiped cache again and installed the latest AOKP nightly, but it still will not boot.
I can start the bootloader through CWM and I can also get into download mode, but it just won't boot Android.
ADB does list my device while in the bootloop, but I get a "device unauthorized" message.
I've had bootloops before and wiping cache/data/factory reset/installing a new rom always worked, but in this case I am clueless.
What can I do? Is there maybe a way to connect logcat without unauthorizing, or authorizing from CWM, or something?
Do you have the newest CWM?? Or try any other custom recovery
As above, use the latest recovery then manually format system, data, cache preload and data/media/0

How can I do this if I cannot authorize a ADB connection?
If yours recovery works flash the newest version
If not flash a stock ROM via Odin
dalvik cache

On Cwm click advance and try wiping dalvik cache if that doesn't work install your stock rom

I would suggest booting to boot loader. Then....
Fastboot format cache
Fastboot format user data
Fastboot reboot
Note that this will wipe your SDcard and data.

help to save data with recovery (note 2)

Dont mean to start a new thread but no one is answering me.
My phone just boots to the "Saumsung Galaxy Note II" screen and is stuck there.
If I do volume up and home, it goes into the recovery screen but I m afraid using odin would erase everything.
I want to save my data, what should I do?
i cant do anything within recovery.
now i have a bunch of of failures..
i can reboot, apply update from adb, or external storage, wipe data, wipe cache.
i did what you told me, to wipe cache, the bootloop persists.
which rom do i use? i dont remember what i used.
Please specify what I need to download in order to save my data, thanks!
