I just bought my TF700 and comes with JB 4.2.1 and as I wanted to get the files with nvflash so that it can recover from a brick if necessary, we've made a downgrade to Android 4.0.3 ICS V9.4.5.30 WW but I need the V9.4.5 .26 WW to work nvflash.
The link for that firmware in http://forum.xda-developers.com/showthread.php?t=1946456 is down and on the ASUS website is not that version.
I searched the web and I've only found one site but no MD5 and do not want to stay with an expensive brick on my hands¡¡¡
Can someone give me a valid link or the file in question?
Thanks in advance.

You cannot downgrade to 9.4.5.26. The 9.4.5.30 and later bootloaders only allow flashing bootloaders with the correct signature, and reject all versions earlier than 9.4.5.30.
And yes, that means you cannot get the blobs for nvflash. But don't worry too much - you just need to be able to read instructions and be careful to keep your custom recovery up to date when you update your bootloader, then you won't need nvflash.

Ok, thanks for your answer _that,
I d know this limitation, also I have a Prime and I got the blob files without a problem using nvflash long ago.
I'll update the latest stock bootloader to flash a rom JB 4.2 without problem.
thanks for your help.

The same here. If you find an answer somewhere else please let me know.
Gentlemen,
First you should do the NVflash tool to backup your golden bootloader (very important, this will help you to relock and unbrick your device).
Second, install Voodoo OTA root keeper then use OTA root keeper to make a backup.
Next:
If you want to upgrade to .30 version:
Download the correct version of tf700 (US, TW etc..)
Extract the zip file, then rename to something like recover.zip
Boot into your custom recovery and select recover.zip then flash away.
If you want to upgrade to JB version, you have to reflash your twrp(no longer work with JB) with the new CWM version then follow the same steps above. Detail instructions are in the link below.
Here is the link on "How to"

Thank you very much for your assistance.
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!
I have rooted my TF700, but have not unlocked the bootloader yet. I had to downgrade from JB to ICS so i am on the .30 firmware. Should I manually update the firmware to a JB firmware even though I am running ICS? Is there an adavatage, or will the firmware actually install JB back on? Also, when I load a custom ROM, should I also load an updated firmware?

What do you mean.
What would you like to do? Get back on JB (rooted, and locked bootloader) or do you want to flash custom roms, which require an unlocked bootloader?
I guess what I'm asking is, when I run a custom ROM, should I flash an updated firmware?

That depends. I am not that familiar with downgrading, so if you could turn off your tablet.
Then press the power button while holding the volume down button.
Then you should see 'bootloader version' somewhere on the left top corner.
If you could note that down and let me know, that'd help a lot.
It could be possible that your bootloader is still the one from before downgrading. If it is, you can start flashing roms as soon as you have unlocked your bootloader.
If it has downgraded too, you have to
1) Install Voodoo ota rootkeeper & make it protect your root
2) Flash the official latest firmware version
3) open voodoo ota rootkeeper and restore your root.
I think there's a walkthrough for your case somewhere in the general thread. Look for 'walkthrough' there, you should be able to find it.

Depend on the rom build. If the rom build on JB, then yes, you need to flash JB bootloader if you're on ICS. Custom rom only contained rom and kernel.(sometime without the kernel so you need to read the instruction). So if you're on ICS you need to flash JB bootloader (either just flash the bootloader alone or flash the entire firmware which included the boot loader). Then you can flash JB custom rom. If you're talking about the new CleanRom, it's on JB (so you need JB bootloader) and has option to flash stock JB kernel or custom kernel. For me, I always flash the full Asus stock firmware first to make sure I have everything then I flash custom rom. Of course, you could just flash the stand alone JB bootloader then flash Cleanrom.

Ive decided too take one of tf300s home from work to help feed my root hunger (also running cm10.1 on htc evo 4g lte)
This tablet is currently running 4.0.3
Assuming i will be walking the custom ROM road, should I leave tablet at 4.0.3 or upgrade to JB? I won't have my p c to perform fastboot until next week, this is why i ask.
Thanks in advance :beer:

I would suggest moving up to JB. I've been using CM 10.1 (which is running 4.2.1) on my TF300T and it's been great. The UI and options are better on JB than on ICS, even though ICS was a pretty great step up.

I also just got my tablet now and I'm holding the firmware update while reading, what do you advice? push to OTA or unlock,root,then custom rom? I thought I saw few others having problem with JB is that OTA JB? That's why I'm not pushing any OTA updates for now.
Thanks in advance!

1st solution (That I've made)
Don't update to JB now.
Rooted and unlock in ICS
Backup your root with OTA Rootkeeper
and after JB update by OTA and restore your root with OTA ROOTKEEPER.
2nd Solution:
Or unlock and root your TF and use the NVFLASH tool (with pre-JB bootloader)
3rd solution:
Go on OTA JB Update
Unlock your TF
and use this guide : [ROOT/ROM] Root Stock/Deodex Firmware 10.4.2.20 (US/WW) | Insecure kernel ! when you are on the version of firmware
Go to my index and you will find all the links that you need

Thanks for your help here's what I did:
-Unlocked using APK
-did NVFLASH tool
-flash CWM
-root
-install OTA Rootkeeper
Now I want to install hydro and I know I have to be in JB boot loader the only question for me now to be able to proceed is:
-Install the pending OTA JB update (I dont know if this will proceed installing since it was downloaded while Im stock, I'm afraid it will brick my device since Im now unlocked,nvflash,rooted)
OR
-Just DL latest from ASUS (ASUS Transformer Pad TF300T Firmware: V10.4.2.20 Only for US SKU (Android 4.1)) Can I just install the latest or I need to install pre requisite update first?
THEN
-Install compatible recovery for JB
-Install custom rom

It's really easy now that you're unlocked, rooted and used NVFlash.
I suppose you're still in ICS.
Backup somewhere all of your files (stock rom, nvflash file etc...) use Titanium backup for save & restore your apps later
You can use both process for update your TF
The OTA update, and every time, you are going to have to restore your root.
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.
