Important: before attempting to flash this ROM, please understand the risks to your device, which include the possibility of causing it to enter a bootloop, causing a soft-brick, or potentially even a hard-brick. Understand that the chances of causing a problem which cannot be fixed is very low, but still a real possibility. If something crazy should go wrong, and you end up with a broken device, do not blame anyone but yourself. Consider yourself warned.[/CENTER]

Here are a few things you should do before starting:
Create a full NANDroid backup.
Backup your /efs partition to an external location, such as your computer. A great tool to do this is provided by lyriquidperfection — EFS Pro.
Ensure that you're running a 5.x version of ClockworkMod Recovery.

Instructions—
Using CWM, make sure to wipe data/factory reset, then wipe cache, and then go into advanced, and wipe the Dalvik cache too.
From there, flash the ROM (JellyBeanAlpha.zip).
Afterwards, repeat the wipe step (step #1).
Continuing on, go into advanced and fix permissions.
After fixing the permissions, go back and flash the kernel (zIMAGE-JB.zip) — this will fix the mobile data connection. Then flash CWM-SU-v0.89_fixSU.zip, it will get SuperUser working on the ROM.
Finally, reboot the device.

Downloads—
ROM: JellyBeanAlpha.zip | mirror #1, mirror #2, mirror #3, mirror #4, mirror #5, mirror #6, mirror #7.
Kernel (to fix mobile data): zIMAGE-JB.zip.
SuperUser fix: CWM-SU-v0.89_fixSU.zip.

What works, what doesn't—
Working: device boot | LED-flash | SD card (internal-only) | MTP (can't copy files) | ADB | Vibration | SuperUser | GSM (courtesy of bpear96) | Network Data (courtesy of stormtroopercs) | logcat (courtesy of edint3000 & bpear96, again).
Not working: WiFi | Bluetooth | Camera | Google Now/Google Search | Audio | anything else.
