So I would currently like to upgrade my tablet to the Official JB bootloader. I am rooted, and unlocked running Hiemanshu's 9/25 build. I've noticed that many of the custom ROM's I'd like to try list the Official JB Bootloader as a requirement. I have followed the nvFlash tutorial, and now currently have the AndroidRoot 9.4.5.30 Bootloader installed.
So to sum it up:
Unlocked + Rooted
I'm running Hiemanshu's 9/25 CM10 Build
I have performed nvFlash and am currently on AndroidRoot 9.4.5.30 Bootloader
My recovery is TWRP 2.2.2.3
Could anybody provide me with some instruction on where/how to find the Official JB Bootloader, and how to properly install it on my tablet? Thanks for any help!
If you want just the bootloader it is posted in the twrp thread.
Otherwise go to asus.com and download the latest rom.

Done! I was actually on the IRC channel the other day and Dees_Troy himself posted that same link for me. I didn't know it was flashable! I was using fastboot commands to try and flash it but it wasn't working, looks like that was a good thing!

So I recently got a SGS3 for verizon and I was looking to install CM10 on it. On the CM wiki it says that "CyanogenMod on the Verizon variant of the Galaxy S3 you need to load an older bootloader."
I'm not clear to whether this means I just need an unlocked bootloader (which I have now from EZ Unlock) or if I need an entirely different bootloader, because looking at some forum posts for the official CM10.1, it only mentions that I need updated CWM or TWRP.
Any help would be appreciated.

I installed it without modifying my bootloader, just rooted, unlocked and flashed CWM then flashed many CM ROMs (10 nightly's, 10 stable and 10.1 nightly's)
root. unlock bootloader. download rom manager from store. flash away in recovery.
do a search, theres guides EVERYWHERE.

There are guides everywhere, but they don't mention the need to flash an older bootloader, yet the how-to guide on the cm wiki says to. A little odd don't you think. I just want to get my facts straight before I turn my 2 day old sgs3 into a brick.

What they mean by the older bootloader is to unlock it. The way we unlock the bootloader is with a leaked EC build that was never officially released for our phone. So just do what others are saying, backup your imei/custom recovery/root/unlock bootloader and flash away
Thanks, that cleared up things for me.
But one more question, I didn't accept the OTA to JB when I first got this phone and I'm still on ICS, can I go from ICS to JB or would I have to accept the OTA/ flash JB through odin first?
This also applies to if I wanted to go from jb to ics. Can I just flash an ics Rom over a jb Rom or is Odin required.

The unlock and root guide is very good. If you have the latest stock rom installed you will have the latest bootloader.
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.
How do I identify what version of Bootloader I am running. I am rooted and unlocked and have TWRP installed and also running the Hydro7 ROM. Looking at other ROMS I need to have the JB Bootloader installed. How do I check this?
Thanks in advance.

You can check your bootloader version in the bootloader menu/screen.
Hold vol- & power to boot to bootloader and the text in the top left of the screen will show your bootloader version.
Hydro 7 requires a JB 4.1 bootloader and is based off JB 4.1 - 10.4.2.20 - so if running Hydro 7 you are currently on a JB 4.1 bootloader.
Alot of customs roms are now based on a JB 4.2 bootloader, so if wanting to flash a rom that requires a JB 4.2 bootloader you will need to upgrade your bootloader first.
If upgrading to JB 4.2 bootloader please ensure the you flash the correct recovery, only the -4.2 versions of twrp are compatibly with the 4.2 bootloaders. Flashing a non-4.2 version of twrp or cwm will brick your device. Have a look at my how-to is sig below for more info.
If you need any help in doing this or more info just let me know.
Hi pjc21, thanks for the reply that clears up my bootloader question and your follow on information. I can now confirm that I am running bootloader "10.4.2.20" and TWRP "2.4.3.0".
So just to confirm after reading your instructions about upgrading my bootloader to "JB4.2" all I need to do is to follow your instructions and flash firmware "V10.6.1.15.3 Only for TW SKU (Android 4.2) 2013.04.23 Update" and TWRP "openrecovery-twrp-2.5.0.0-tf300t-4.2.blob".
Is this correct?
As ever your help is greatly appreciated.

I am on this bootloader us-epad.10.4.2.13.20120907 and twrp 2.2 with CleanRom I will like to flash KickKass MM but i need the new TWRP.
Can you point me to a guide on how to upgrade the bootloader ?
Hello guys,
I tried to find an answer for my question on the forum, but didn't succeed. Anyway, I have an Asus TF300T with the following specs:
Bootloader WW_epad-10.6.1.27-1
Unlocked
Custom Rom SlimBean 4.3
TWRP 2.5.0
I'm looking to upgrade to this ROM CROMBi-kk which require :
Bootloader 10.6.1.27.5 and TWRP 2.6.3.1 (at least)
My question is :
How can I update my Bootloader version to the latest one 10.6.1.27.5 ? (OTA do not show up anymore since the unlock/rooting etc... So I need to do it manually)
And if I succeed, can I flash TWRP to the latest version simply by using ADB?
I've already got the latest bootloader on the ASUS Website, but I'm pretty ignorant on how to update my tablet with it
Cheers!

10.6.1.27.1 will still work fine so you don't need to upgrade the bootloader.
Just flash the correct version of TWRP over fastboot (not adb)
