Before anybody says to use the search function, I've been looking through the general topics non-stop for one that applies to my situation, and either it slipped through the cracks (likely) or it doesn't exist (not likely).
Basically, my tablet is rooted and unlocked, and I'm on ICS; the first one that had face unlock in it. I'd really like to update my tab to JB, but I need to be pointed toward directions for updating a rooted and unlocked tab. But on top of that, I also need recent instructions, because I know that earlier attempts at getting this thing updated have resulted in lots of bricked tabs.
If anybody could tell me if it's possible to update my tablet to JB right now, I'd appreciate it, and if someone has figured out how to do it, can you please point me toward that thread? I'd really appreciate it.

I'm in the same configuration, custom-ics-rom with twrp recovery on unlocked device.
I believe the first thing to do is enabling NVFLASH, that will make things safer also in the worst cases.
I did that and now hopefully I have an unbrickable device.
I'm a bit confused on how to go forward, I know that there are two versions of twrp, maybe I should install the JB version, booting inside it and then flash the downloaded JB update from ASUS site, or use the twrp for ICS for flashing and after that install the JB version ?
Anyone knows what is the correct option ?

Keep ICS, as JB will cause much trouble especially if you are rooted, trying to OC and is generally slowein my opinion
I prefer to try it anyway, tomorrow I will try flashing, after all if something will go wrong I should be able to recover with nvflash.

Thank you, Grim. That's disappointing to hear about JB, but if you think that my current build is better than that (which makes sense considering I've seen at least one thread about downgrading from JB to ICS), then I will keep my tab on ICS for now, and thank you for your input, I appreciate it.

If you have twrp recovery, can't you download the jb ROM from the Asus site for your region and flash it in? I'm unlocked and that's how I upgraded one version of jb to another, but my ICS to jb was ota, so in your case I can't speak from experience. There is a full upgrade, and root guide in the general section.

I just managed to do what you re looking to achieve.
I m pretty noob so it tok me a whole day to figure it out.
So first download jb update on asus website (pick the right one for ur type of tf300)
Flash it through adb
At that point i got jb installation working but bootloop
So i flashed jb version of twrp (adb)
I then went in recovery and flashed clean rom 2.5 which worked flawlessly
Just for the fun i did factory reset afetrwards and stock jb eventually launched right

I successfully installed jb following the guide on this site, the only thing that was not working was the flashing of the stock rom, neither given options worked (fastboot flash recovery or fastboot flash system) , I discovered that our eepad has a partition nmed staging used for firmware installs. I then flashed with
fastboot flash staging blolb
and all went good.
Btw I find the JB better than ics, more responsive and smoother, and also if it is not yet overcooked.
Hey guys, I just ordered this tablet today on sale from newegg. Pretty excited for it! I had a nexus 7 I purchased today but for $30 I feel I got a lot more tablet.
I have only rooted two devices in the past, my S3 and Droid X2, both were either 1 click roots or simply plugging into odin and flashing a rooted image.
I saw there were two different guides, one was very in depth..I also heard of tablets coming with a new software update that might not be rootable yet? Which is the best guide to follow for rooting this device?
Also, I noticed there are two CWM recoveries, one for JB and one for others. When I update to the latest JB OTA, and flash that, what happens when I install a custom ROM, should I flash the 'other' CWM then?
Thanks for the answers! Can't wait for this tablet to come in the mail!

For rooting and installing custom recovery, check out the videos on the link there, especially the ones from allaboutandroid. There should be a step to unlock your tablet there as well...
I'm guessing you're still on stock ICS, yes? In that case, after you apply the OTA JB update from Asus, you should install the CWM for JB only. You don't lose recovery after you flash a custom ROM. Do not, however, attempt to flash a JB ROM on ICS recovery, and vice versa. That would soft brick your tablet. Hope that helps

Link to a post that explains the rooting process as well.
Thanks man. That first guide is a little overwhelming at first. Lots of information haha. I haven't received mine yet but really looking forward as its my first tablet. Really appreciate the links and everything. Unlocking the boot loader seems easy enough!
Edit: should I apply the JB OTA and then unlock boot loader? Or does it not matter since the boot loader unlock works on ICS and jellybean?

Well, it doesn't really matter which step you do first, but you might as well apply the OTA first, and then unlock and flash custom recovery + root all at once. Also, there might be a chance that you won't be getting the OTA notification from the tablet itself if you unlock first (some users reported this, although it doesn't seem to be across the board)...
Update: http://forum.xda-developers.com/showthread.php?t=1845377
Another link for rooting and recovery, this one labelled 'noob-proof'. If you're installing the OTA first, start from Step 3..
Haha thanks. Really appreciate it. As I said all of my past rooting experience has been simple. This one is a bit more in depth but I can follow directions just fine
I recall reading somewhere about two types of recoveries. One for stock JB and one for everything else. If I flash a custom ROM will I need to change my recovery at all if I go with TWRP JB?

Yeap, this tablet was my first experience with android, and from what I heard there are more steps involved here than with the other tablets/phones. I actually skipped a step and soft-bricked my tablet once XP
No, unless you want to flash stock-based ICS ROMS, which by now is kinda outdated anyway (they even ported CM10 to the JB bootloader already). TWRP should do the trick for some time

Sounds great, thanks for all the replies. I would hate to get my tablet and accidentally brick it (I would probably cry). It was between this and the Nexus 7 but I feel I made the right choice. My S3 already has a decently big screen, 3 more inches isnt worth $300 IMO. However 6-7 more I think is a winner!
Edit: Ugh, looks like an update was pushed out today. Curious if this will break the rooting methods or not...
I recently purchased my TF700- I wasn't aware of the fact that unlocking the boot loader would void your warranty, and that there was a slightly more complicated process for prepping the TF700 for flashing roms and kernels compared to previous android devices. (This is my first tablet, so I don't know if this is normal for tablets though!) Plus the fact that I need to be on ICS to do everything initially.
And just a BTW, this is comparing it to my experiences w/ the G1, Epic 4G, GS2, and the GS3- where I never actually had to deal with unlocking the boot-loader directly/or having the risk of ruining my warranty.
So basically what happened was that I read through the forums and learned that unlocking the bootloader would void your warranty- and being that it is always risky business + the fact this tablet is a lot more expensive than a phone- I decided I wasn't going to be rooting/flashing roms and kernels and etc, on my TF700. I didn't want the risk of bricking something I just paid $600 bucks for. So I took the OTA update to Jellybean.
With further research though, I found out about NvFlash, and then it would make my tablet brickproof. And that immediately sparked my interest! I read though, that it does not work with the .30 firmware though.
This is where I got a bit confused- I know I can downgrade to ICS (the .30 v tho) and then unlock/root/then flash stuff.
BUT, by me taking the OTA update to 4.1.1 JB, did I **** up my ability to use NvFlash? Cause I really want too unlock my phone and flash roms, but I'm just really scared of bricking my device.
If anyone could help with what my plan of action should be, it would be much appreciated, thanks!
Can't be done unfortunately, you need .26 firmware for nvflash. At the moment you're out of luck :/
****! Well just my luck :/.
I was going to send in my TF700 back in anyways for a replacement since the screen was popping out in the corner, so I guess I'll wait till then!
Thanks for the response!
Just out of curiosity, why doesn't downgrading back to an ICS rom do the trick? Is there something that gets left behind by Asus's JB rom that doesn't get downgraded when you go back to Asus's ICS rom?
Sorry to revive an old thread but I couldn't find a pertinent new thread about this.
Thanks!

You need a bootloader that does not check signatures to install the hacked bootloader. You cannot downgrade to such a bootloader, because all later ones do check signatures, and the unsigned ones are rejected.

Well, Asus had patched the security hole with .26 ICS firmware. They updated the next version of ICS which is .30 and this blocked the exploide. The signature (key) from the ICS .30 is no longer the same as ICS .26. So if you tried to downgrade to .26, you're going to see signature mismatch and it will failed. The signature on ICS .30 and all of the JB are the same, so you can upgrade or downgrade from 30 and up....Here is where the story ended!!
Ah, OK that makes sense. Thanks for the explanation!

Downgrade from JellyBean to ICS
Hi,
I am very new hear and not sure how to start a new thread. I just purchased the Asus TF700t because it was supposed to have ICS, but I found it has JellyBean. Is there a way to downgrade it to ICS?
Thank you.

You need to look around a bit.
I attempted an answer for you in another thread that you had replied in.
Please look here >>>> http://forum.xda-developers.com/showpost.php?p=38530719&postcount=5
Hello all,
I just bought a tf300t that already came flashed with ParanoidAndroid 3.60. It shows that it has a 4.1 bootloader (10.4.2.20) but is running JB 4.2.2. From what I understand flashing a 4.2 rom on a 4.1 bootloader will brick the tablet, but I must be mistaken since it's running fine. I would like to update to the 4.2 bootloader and flash a different rom since the one currently on it is a bit sluggish and unstable. I've read around the forum but the posts I've found usually start with the tablet having a stock rom. Any help would be greatly appreciated since I don't want to brick this thing
I'm going to use this guide to get it back to stock, but i'm a bit confused on one part. It says 10.4.2.20 is supposed to be running JB 4.1 but my tablet is not. Does that make any difference?

whay not just install twrp and make a nandroid back up then flash a custom rom like cromi-x, performance will be way better and the nandroid backup will help protect your tablet (although ive never had to use it lol)
Please forgive me if my questions have been answered many times but I really don't know what to look for in the search menu to address my questions.
1. I have rooted my phone and installed Liquid smooth but I went back to stock (still on 4.1.2 TW) and would like to update to at least 4.3 or higher. One issue I'm having is that when the OTA comes through and I go to update it gives me an error. But even before that as I am rooted it boots into TeamWin and wants me to install from there. It has been a while since I've done anything with the boot loader and I'm afraid to install from there and/or if that is wise. (frankly I've forgotten how)
Honestly I just want a quick way to install the update to 4.3 or 4.4 or whatever the next OTA is so that I can move on. I really don't even want to mess with it much right now as my life is way to busy.
2. My search so far has shown me that others are having similar issues but they are saying that the ota update is messing up certain things with their rooted phones (haven't found the answers I'm searching for either). Should I wait on updating? If so, how do I get the ota to stop wanting me to update my phone?
Thank you for any help you can provide.
wouldn't you know, that as soon as I submit this post I find another thread dealing with the same thing... Sorry for the clutter.

Since your life is too busy and you don't want to mess with your phone anymore, your best bet is go back to stock 4.3 which is very good by the way, very stable, smooth and bug free. After so many complaints from my wife I rolled it back to stock 4.3 and she's so happy now.
1. Flash stock MF1 here http://www.androidfilehost.com/?fid=23134718111254196 , just unzip the flash with Odin
2. Your phone should take the 4.3 OTA update and you're home free.

Thanks so much, but now that I've put a little more research into this update I'm seeing that others are having issues with tethering and that would be a serious issue for me.
Also I used twrp to root my phone and did not use odin so I don't know how to flash with odin (or even have the files on my computer) is there a way to us twrp?
It looks like I will need to put a little more time into this than I wanted. Anyway, thanks for the help.

No issue with tethering for me, just root then install wifi tether router.
