If you followed the instruction and asked you to flash full Asus firmware .30, then you don't have JB bootloader. You only have ICS bootloader.

If you downgraded you were already on JB... you couldn't really have downgraded if you weren't. If you did downgrade from JB to ICS, that means you have the JB bootloader. The JB bootloader sticks with you, even if you downgrade to ICS.

Maybe it works even with the ICS bootloader.
I know a nice way to find out which bootloader you have: Look in /proc/cmdline - if it contains "vmalloc" then it's the ICS bootloader. They removed this parameter in the JB bootloader.
You cross-posted this question in the CleanROM thread where I just answered. I'll copy my reply out here:
The easiest way to check is booting with VOL_DOWN pressed -- if you ''immediately'' get four options (with "RCK" being the leftmost), you're running a JB bootloader.

Ran out of thanks for today, so I'll have to do it manually: thanks.
I didn't flash .30 stock, but as far as I know, only the JB bootloader did this. You may very well be right, however, because of the aformentioned fact I did not actually flash the "full" .30.
Furthermore, the current version of CleanROM has the prerequisite of a JB bootloader, so in this case it is a moot point: the OP has a JB bootloader (check Scott's OP at: http://forum.xda-developers.com/showthread.php?t=1919851)

Such a "prerequisite" can be any of "I've never tried anything else" or "I don't want users to try anything else to reduce possible support issues" or "It really doesn't work".

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.

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

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).

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.

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?
I've heard that the JB bootloader gives a few, quite nifty new features. My question is how should I go about installing this bootloader? I've seen mixed responses all across the forums lately about how and where to get the JB bootloader.
Anyways, I am unlocked and currently running Cleanrom 1.3. Great rom.
I'm still on the .22 bootloader.

You may want to install the AndroidRoot bootloader first to make the backup files required for wheelie and nvflash. Doing this before flashing the JB bootloader is your last chance.
http://forum.xda-developers.com/showthread.php?t=1901479
Yea you should be able to just flash it from your recovery and be done with it.
Alternatively, you can do it with fastboot (which is handy if you flash a ROM that requires the JB bootloader while still using the ICS bootloader). See my post in the CM10 thread for more on that.

sandmann241 said:

Yes. The JB Bootloader comes with the official ASUS update.
My TF700 is currently on JB (not sure which version since Build Number isn't showing up on Settings menu anyway), rooted, and unlocked with custom ROM CROMI 3.0.4. I can see that last month there was a new update for the tablet being 10.4.4.25, and I want to update to that to see what improvements there are. The things I'm concerned about needing help with are:
1. How do I update it? As far as I know, I have two files on hand for the new update. One that's about 400+MB from the Asus site, and another being from sdbags' topic introducing his latest version of CROMI that's being about 8-ish MB. Which is the correct one to use?
2. Will I lose my root access after updating?
3. Is there any other precautions I should take before and after I update?
I'm sorry, I'm still a newb at doing this kind of stuff for Android and I've been looking through a lot of threads here on XDA to find the answers I'm looking for. Much help would be appreciated, thank you.

The correct way to upgrade CROMI is to install the latest version of CROMI - it includes the firmware updates from 10.4.4.25 (but the bootloader is separate).
For the bootloader, you can check its version by holding down "volume down" (left) while powering up - the build version should be displayed in the tiny text at the top of the screen. All bootloaders from 10.4.4.18 to 10.4.4.25 are identical, so if you have any of these, you can just install the latest CROMI. Otherwise, in addition to the latest CROMI, also flash the updated bootloader from sbdags.

2. No, if you install CROMI and not the stock ROM.
3. Backup your data before, and then follow the instructions in the installer.
So there isn't any importance for me to really update to 10.4.4.25? I see there is a log of what it fixes, and I was just interested about updating my bootloader to it. Also, how about the two different bootloader update files?

The full firmware includes the bootloader, the stock recovery, the kernel, and the system image. Updating only the bootloader is pointless - the changes you read about were made in the kernel and the system image, not in the bootloader.
Which "two different bootloader update files" are you talking about?

Did you even read my previous post? "The full firmware includes the bootloader, the stock recovery, the kernel, and the system image." That's the difference.
I've got a similar question. I'm on the .30 bootloader, which I've unlocked. I don't exactly remember why I'm on it, but if memory serves, before unlocking/rooting, I did the official upgrade to JB (which updated bootloader to 10.xx.xx) then I had to use the blob to downgrade to .30 in order to get the Asus unlocker to work. I've since flashed CWM Touch 6.0.1.9 and am running a fairly recent CM10.1.
So, am I now able to upgrade the bootloader to a newer (read official JB, or, more quantitaiively, 10.xx.xx) version? If I understand correctly, I can use a blob to flash a new "firmware", which would include the bootloader, rom, ril (we have these right?), etc. However, once I do this, I will be stuck on a stock recovery and rom, correct? If there is a way to upgrade the bootloader and keep it unlocked (/unlock it after), what are the steps involved?
I'm fine with the .30 bootloader, but it's ridiculous that the "Reboot to ..." options do not work. OK, so it's not ridiculous, it's just a bit inconvenient and has been causing me to not flash as many nightlies. My followup question would be, does the JB bootloader address this "issue"? And, correct me if I'm wrong, but the only way to get ROM Manager or GooManager to be able to do scripted flashes is to have these reboot options working, right?
TLDR: Have unlocked .30 bootloader, want JB bootloader but want it to be unlocked. Can it be done? Do I really want it?

In sbdags' CleanROM Inheritance dev thread, he offers bootloader-only installers - you can use these to install only the current 10.4.4.25 bootloader and keep your current recovery, kernel and ROM (no RIL on a WiFi-only device).
Warning: Make sure your recovery is compatible with a JB bootloader on the TF700 - too old recoveries (created for ICS) are known to cause hard bricks with the JB bootloader.

Hey, thanks for the prompt reply. Can you please confirm that this will let me keep my bootloader unlocked? Also, if this does happen to **** things up, do I have any recourse (ie. can I re-flash another, older, bootloader that will allow me to boot?). As I'm on the .30 firmware, I don't have the ability to use NVFlash. Also, will upgrading the bootloader make the "Reboot to.." options work?

Once you've unlocked your bootlader, updating it to the lastest (and presumably greatest) will only updat its code, and not relock it. (If it did that, I bet a lot of the users with trouble could've gotten a free warranty reset! -- ASUS wouldn't do that, trust me.)
For completeness' sake: if you did not unlock the bootloader before, the unlock tool will remain as functional as it would have been in the first place. If you can't unlock the new bootloader, you couldn't have unlocked the old one either (issue is on ASUS' side, well referenced on the forum).
Reflashing an older bootloader: no, unless you have NvFlash and the concurrent backup files-- I didn't gather you ran that procedure before upgrading to .30...
TL;DR: your bootloader will remain unlocked if you unlocked it prior to updating, and remains unlockable if not.

In any case, before you use any "reboot to recovery" tool after flashing a new recovery, always test the new recovery by starting it at least once with the power/volume button combination.
