Please read previous posts on JB 4.2 vs 4.1 bootloader. It is nearly impossible to down grade to a JB 4.1 based ROM once you have installed a 4.2 ROM. I believe it changes the bootloader and will leave you stuck on the boot screen. I recommend the following (I assume you have an unlocked bootloader).
1. Update the boatloader with TWRP JB 4.2 using fastboot
2. Install any ROM stock or a custom JB 4.2 ROM
Good luck!

That has not been true in my case. Link. I've gone from 4.2 back to 4.1 a few times. No need to panic.

I'd suggest you go back to official 104220 and find out what kind of touch firmware you have. This topic has been discussed numerous times. Go to /etc/firmware/touch/ folder and tell us what you have in there. Check /settings/about tablet/touch panel firmware/ to see what version shows. We'll go from there.

Hello to anyone who offers to help!
First post ever on XDA.
I just installed this: http://forum.xda-developers.com/showthread.php?t=1893714
Jelly bean release on my TF300T, however, I seem to be stuck in a bootloop.
Stuck in the screen where it says "The Device is unlocked" in the top left corner.
On the thread above I flashed the first out of three options (untouched official latest firmware ;stock kernel ;su & Superuser for root access !).
I did wipe both cache and dalvik before flashing with TWRP.
Any help is appreciated

Were you already running jb before you flashed the ROM? If not, get the latest ICS release from Asus and flash that, then upgrade to jb. If you were already on jb, flash that again via twrp, then see if it boots fine, if it does, then begin your root process again.

All the ROMs that are available right now for JellyBean require that you are already on the JB bootloader. If you are NOT on the official (OTA) JB update, then I suggest you read up on NVFlash before you do cause you can't go back to the ICS bootloader once you update to the official JB firmware 10.4.2.9 or .13.

Hi Guys!
I also got this beauty today! Still charging!
So.. what should i do 1st? Put the last ICS and bootloader? And only then go to JB? Firmware?
Im confused....
Is it safe to downgrade from stock jelly bean to stock ICS?
There reason I'm asking is that I wasn't able to get the Jelly Bean OTA to work so I manually flashed the Jelly Bean OTA using Odin. The one I flashed came pre-rooted and pre-loaded with a custom recovery. I want to have a completely untouched stock version of Jelly Bean, something I haven't been able to find here or elsewhere (I would get this by doing an OTA update to Jelly Bean from the stock ICS rom that I flash).
I'm thinking that the reason that I couldn't get the OTA to flash (it gave me an update fail notification every time) was because I wasn't completely stock on the previous ICS version, even though I had unrooted, relocked the bootloader, thawed bloat, etc.
If anyone could answer the first question, and the others I've raised, that would be great.
(I know that it is probably OK, but I wanted to double check since it was a major no-no to downgrade when I had a Droid Razr Maxx).
Yes, you can safely downgrade in order to take the OTAs.
Yes, your past OTA attempt probably failed because you weren't fully stock in some way. There is an error log stored on your phone that you could have checked for the exact cause. As a general note, OTAs require you to be on stock recovery, but not necessarily Unrooted.
You mention that you are unable to find a stock image file for the JellyBean update. This file is readily available here at XDA, and can be downloaded from the following thread:
http://forum.xda-developers.com/showthread.php?t=1974114
Performing only Step 1 from that thread would leave you with a fully stock, unrooted, locked bootloader JellyBean ROM.
Sorry if this question has already been addressed. I updated to stock 4.2 Asus firmware. I'm able to run stock-based ROMs, but I want to run Paranoid Android. Atm, I can't run it cause of the 4.2 bootloader. Is there some way to downgrade from 4.2 bootloader to 4.1? Would it do to unzip the 4.1 firmware from asus once, and flash that?
Thanks in advance
Edit: I was able to successfully downgrade from 4.2 to 4.1 by unzipping the asus firmware once and flashing it normally in twrp. That got the 4.1 bootloader back too. I have flashed PA 3.15, and it's worked fine

That's pretty much what i ended up doing Thanks for the quick reply
I'm currently on Android 4.1.2 using Baked 6 and I want to upgrade to Baked 8, or anything on 4.2 for that matter. If I update a ROM, does this also mean it updates my bootloader? If not how to I properly update my bootloader without bricking my tablet? I've been reading around but there's so much data on the forums that I feel like I'm going to accidentally make a mistake

No flashing a custom rom will not upgrade your bootloader, only the stock asus firmwares will do this or a custom made blob file.
There are several methods to upgrade your bootloader to a JB 4.2 bootloader which can be found here or here. I prefer using the fastboot method for upgrading but up to you. Just make sure that once you've upgraded your bootloader to a 4.2 bootloader that you flash a -4.2 version of twrp or you will brick. I would suggest upgrading to JB 4.2 - 10.6.1.15.3 & twrp 2.5.0.0-4.2 as I find this more stable than 10.6.1.8 & twrp 2.4.4.0-4.2
If using the fastboot method and you need any help with any step just let me know.
Currently my phone is on 4.1.2 bonestock ROM with [VRBMF1] and I believe the bootloader is unlocked. I've been out of the loop for so long that I dont know what the best way to get to 4.3 is while keeping my root and bootloader unlocked. Any help is appreciated!

First, a caveat: Android 4.4 was just released for our phones a couple days ago, so you may want to wait a little while and see if any ROMs based on it come out. As of right now, there isn't a rooted version available, so 4.3 is your only option.
If you're on Bonestock, your bootloader is in fact unlocked. You can flash any of the 4.3 ROMs you find in the Android Development section. You should update your recovery first, I use TWRP version 2.6.3.0, the newest version is 2.7.1.0.
You should also flash the newer modem for the phone, VRUCML1, first, you can find that here under the Modems folder: http://d-h.st/users/invisiblek/?fld_id=35604#files. Only do that if you are actually going to update to a 4.3 ROM. Then you can flash any ROM you like: CleanROM 8.2 would be my pick, there's also Alliance and MOAR.
