For those of us on the TF300 JB bootloader you can revert back to ICS using my instructions in my other post here only be sure to grab the new .30 firmware: http://forum.xda-developers.com/showthread.php?t=1873635
Not only is ICS running smoothly again thanks to the bootloader but THE .30 BOOTLOADER ALLOWED THE JB KERNEL TO RUN!!
That's right I was able to flash my own TF300 ROM which has everything but the kernel removed from the blob and it ran JB while leaving the bootloader intact.
nice! good to hear asus has things figured out.
I'm guessing this is part of the prep for JB with the bootloader supporting both.

Yes, but you have to extract US_epad_user_9_4_5_30_20120907_UpdateLauncher.zip to US_epad-user-9.4.5.30.zip and flash it.

I've flashed it several times today. You will have to re-install TWRP via fastboot, and then flash SuperUser, if you care about root.

I know it's stated that you have already done this, but I really don't want to screw something up and I don't have NVFlash to recover from a hard brick.Can you, or others, confirm that you can indeed move from the .13 JB bootloader to the .30 ICS bootloader successfully and then be able to use the NVFlash?
Edit: Oops, I guess this is for the TF700 only, or will this work on the actual TF300 as well? Anyone know?

After my thread for the TF101, here are my first repackaged OTA updates for the TF700:
First of all let me make this clear:
If you have root and want to keep it, use OTA Rootkeeper.
The original recovery is removed from the blob, so you won't lose your current recovery.
If after flashing one of these zips you still have the OTA update notification, do this:
Go to Settings -> Apps -> All and clear data from DMClient.
Current OTA 9.4.5.26:
US version:
us-9.4.5.22-to-9.4.5.26-TF700-CWM-v1.0.zip MD5: 2C6C763D0A7618E4AB4CB530D714F833
WW version:
ww-9.4.5.22-to-9.4.5.26-TF700-CWM-v1.0.zip MD5: E9597AD7C18483445A1F006D91A44C1B
IMPORTANT! If you deleted/changed some files, these updates will NOT work. These updates are meant for people on a stock rooted rom.
Sweet I know a few people were looking for a flashable OTA update.

AFAIK cwm zips are compatible with TWRP.
It's a generic name which is supported by most recoveries.
(TWRP or CWM) As far as we are able to unlock our TF700... That not my case...
But it's a good news for those who can
Lizard, a better title would be "[ROM][FLASHABLE]" or something. People tend to get very confused when you say "CWM" because they think no other recovery can flash it .

I've changed the title to flashable, since I don't consider the update zips to be roms. I hope this will take away some of the confusion.

You cannot downgrade from 9.4.5.30 to 9.4.5.26; the 9.4.5.30 bootloader and above accepts only signed bootloaders and the older ones are not signed.

That sucks, I didn't flash .30, it came with it already installed. I'm used to flashing my phones, so it should be no problem flashing my tablet. Thank you very much for your help.
If you've flashed roms on other phones or tablets in the past then you should be fine. Just don't do anything crazy and you shouldn't brick it. I don't have NV Flash capabilities on mine, though I had the chance to but updated my bootloader anyway. Doesn't bother me as I'm not a dev and won't be doing anything crazy on mine. I've done plenty of flashing on many phones and the Asus Prime in the past, so I'm not worried about it

Guys,
a post with a flashable bootloader for both ICS and JB would be useful.
I've borked a JB rom and my CWM backups were not working because of the bootloader.
I had to flash ASUS stock back to get the bootloader.
Some zip files would be useful in case someone wants to go back to ICS
Much appreciated.
Abe
what if the JB bootloader sets some e-fuses and reverting to the ICS bootloader bricks the tablet?
without NVFLASH I wouldn't even attempt such a thing.

Asus wouldn't b that nice would they?
On Galaxy Nexus I do that all the time. They have an ICS bootloader and a JB one. I can check the version in Fastboot mode.
I am trying to flash some JB ROMS and if I fail all my CWM backups are useless since the bootloader is the incorrect one..
The tab gets stuck after restoring I assume because of the incorrect bootloader.
Thanks
Abe
I attached the ICS bootloader, I would strongly suggest you wait until NVFLASH
for the tf300t is released to mess with the bootloader because you have no way
back if it does not work (no fastboot).

In the official cm10 thread it states that nvflash is not going to work with the jellybean bootloader. I think they where close to a release before jellybean dropped.
here is the post.

As the title says. I uploaded the tf300 firmware while rooted and an unlocked bootloader. I had twrp
I've heard that flashing the 'update' removes root and relocks the bootloader.
I really have no idea how to go back to ICS but i've read that theres a way. I just can't find any clear directions.
just download the new rom from asus and flash it in recovery.
when it reboots you will be back to stock with new bootloader.
I thought the bootloader went untouched by reflashing the stock ROM? (I might be mistaken here, but isn't that the entire issue with not being able to get back to the ICS bootloader after flashing the JB bootloader?)
New ROM has a new boot loader which will flash over jb.

you do need to unzip it since it is double zipped for some reason.
then flash as usual.

No, not yet. For now, you have to flash back to .30, root it then use OTA keeper to save a backup, then upgrade to JB, then restore root.

I was gettin worried, downgrading seems like such a hassle
OFFICIAL JB, TF700, WW SKU, C70 serial 64gb
I just wanted that 3.1.x kernel SO bad.
Now to finally start tweaking/debloating it. I can't believe this BLOATED STOCK firmware runs as "smoothly" as it does, compared to stock .22, stock .26 and stock .30 it is hands down worth the hassle.
I have JB that has portrait mode, IPS+ and I can still plug my NTFS formatted portable hard drive into it, that NEVER worked on any of the custom JB roms working around the 2.6.x kernel.
now to see how vnc-loopback-linux-over-android works!
all the excitement, all over again. I've only had this thing for a little over two weeks, but it's so much fun. I love being on the ground floor with new devices, so many risky experimental things to try.
I'm f'n stoked! Haven't gotten bored with it yet!
Keep up the good work everyone!

Yes, you can follow the soft brick recovery in the "All-In-One" thread to downgrade from JB to ICS .30 without unlocking your boot loader.
So, let me get this straight.
Revert to .30, then root, then use Superuser (I have Elite) to OTA save, then apply the JB update, then use Superuser to un OTA save?

If it's not working for you, you could try to downgrade to .22. Basically, download full .22 version, extract, renamed and copy to your SDcard then use twrp to flash.

OK let start over. This is how i would do this:
1. Downloaded .26 from Asus site.
2. Unzip and moved the zipfile inside to root of internal sd card.( /mnt/sdcard)
3. Rebooted, your device should found the update and prompt you to update, flashed the update. You should be back on .26 with stock recovery and unrooted.
4. Reroot and download OTA root keeper to save root. Run root keeper to save root
5. OTA to .30. (if OTA is not working, let me know).

Sure if you want to, download .30. Tablet should pick it up, make sure you unzip it first. Yes, you're correct you have to upgrade using manual process. Every methods here on XDA are not 100% work for everyone (you already knew that). But it should work for most ppl.

Mate do you actually know what you are saying? The JB firmware from Asus site it's a full rom not just an OTA (incremental) update, this means you can update from any version (do you see any word from Asus saying you must be on. 30 before installing?) because everything will be updated (BL, Kernel, etc) so installing this with TWRP will get you Full Stock JB (yes, you will loose twrp too).

I'm not disagree with you! just saying no one here have tried to go straight before. The only question here is the bootloader between .26 and JB is different and why Asus pre upgrade to .30 before JB? IDK, maybe there is a reason, maybe not. Some how I think they need to prep the bootloader on .30 to be ready for JB? again I don't know.

My personal opinion on that is that Asus did this because they made a mess by letting people install TF300T Jelly Bean on TF700T (that should never be possible with locked bootloader and official firmware) so they updated the bootloader on .30 update so ppl could downgrade from that tf300t Jelly Bean rom.Maybe i'm wrong,but it does make sense and if i'm not wrong TF700T is the only transformer device that can downgrade from JB to ICS so easily.

Guys you can just install the JB firmware from asus. Unzip, flash that file in twrp and boom straight from .26 to JB with no issues. It even keeps all your data.
