This is the guide I used and it worked fine. I wound up with a bunch of force closes after I downgraded, but I managed to be patient and get through them far enough to be able to root the device. It just took longer to get the device show up in the adb list of connected devices.
I think the force closes were related to a gmail widget that I had on my home screen, but not certain of that.

yes decided to follow that guide just trying too back stuff up with out root its tough dont want to loose my dolphin bookmarks etc but with them all being on the internal sd it gets wiped so going to back up as much as i can and root later

+1 for this guide, despite using Mac OSX so the commands deviated slightly when it came to entering them, it was so easy to follow the steps and rooted my transformer first time without a hitch. Good luck for later when you apply the hack.

Just to add not long after putting the stock rom on I visited the developer forum and saw that Prime V1.4 had been released. Have downloaded and flashed it and my TF does seem to have more zip now.

I am interested to see if any of you get a custom ROM and if you think it significantly improves performance.
At the moment, I am quite disappointed in the performance of the tablet.
Been holding off rooting due to not wanting to void warranty, and not positive about how/if can get back to stock for warranty purposes.
I want to be sure it is really worth the effort, and risk of warranty issues.

Rooting questions!

Hello XDA,
I've been searching here/google/youtube but no luck!, I have an Asus Prime that I would like to root and install a custom rom however, my tablet is currently stock running build number 9.4.2.28 update and all the root tools/ guides that I've tryed are not working!
someone please point me in the right direction!
Thanks

Edit: reading> me
anwya...since you want to run custom ROMs, you need to unlock the bootloader using ASUS's app from thier site.
unlock the bootloader
Flash a custom Recovery
flash the ROm of your choice.
if the unlocker app from ASUS doesn't work, then you may have some more work ahead of you.
run the unlocker app and report back here with the results.

ok, but don't I need to root 1st? before unlocking?
Thanks!

I 2nd this. The only way to go back to ICS is to get another tablet with ICS on it. Once you are on jb, that's it. There are so many changes under the hood with the jb update that it's most likely not going to happen.

No, you are not completely right.
It must be possible somehow since the Asus Service Centre of my country (Hungary) offered me to put back the ICS ROM when I complained about the bugs of the JB upgrade. They wrote me they would do it free of charge, covering by the warranty, because my ROM it's pure stock, without unlocking.
It's another story that now, after receiving the fresh OTA update I may not want to get back to ICS...

I agree with the above poster. I was locked and did the OTA JB update, which completely borked by tablet. I sent it back RMA'd to ASUS with JB and got it back with ICS. It was definitely the same pad since I had a long scratch on the back. They were able to do it somehow

Perhaps they were able to do something similar to nvflash only more enhanced. When I made my statement, it was referring to us normal tablet owners, not to those that work for the manufacturer. . This is good confirmation though, thanks for that.

No problem. If we were somehow able to get our hands on whatever ASUS has to be able to do that, we would be able to unbrick ourselves in the future if anything went wrong. That would a powerful tool to have

Wouldn't they have the tools necessary to flash literally everything, so any old stuff including bootloader would effectively be overwritten, and then no problem for reverting back
I suspect that they have dedicated hardware for this purpose, makes it way more secure

I'm too scared to try it, but I might be tempted if someone with NVFlash that can recover if it doesn't work, but the following link HERE says we can revert to the .30 ICS Bootloader from the .13 JB Bootloader.
Can anyone confirm or willing to test the capability for me?

It is already confirmed by xplowild on his CM10 thread. He was using NVflash to jump back all the time.
Because I am on JB I cant confirm it myself, cause I cant use NVflash

The thread talks about downgrading from .13 to .30 by flashing the .30 firmware update WITHOUT using the nvflash, that's what I was wondering if it was confirmed to be able to downgrade to ICS to the .30 firmware without needing NVflash?

There is no way. I tried all methods. You cant get the old Bootloader to flash, because of the signature missmatch
BTW
You can flash any ICS Rom over JB. It just want boot. So its not in any use to do so.
Just never do the bootloader wipe and you will be fine with fastboot.

Anyone have any of the threads where someone bricked going from JB to ICS? I have searched and searched with no examples!

I actually tried flashing ICS over JB as an attempt to downgrade. This was my process.
I tried flashing a custom ICS rom, and nothing happened, practically. Of course, I wiped the Rom, so when I tried to reboot, I was warned that no Rom existed. I tried flashing the stock rom from Asus, and that did not work either. So I use fastboot to push the ICS recovery to the tablet. When I attempted to reboot, it failed. When I tried to get back into recovery, I received a message under the message "This device is unlocked" in red letters saying, "Signature mismatch." At this point, my stomach was in my throat. I rebooted into flashboot, and sent the jb recovery image back to my tab. This was when I reflashed a custom JB Rom, and gave up. I know that I could've tried using fastboot to push both the bootloader from Asus and an ICS recovery image, but seeing those red letters was enough warning for me.
So I'm now JB for life, and I'm fine with that!

Who need ICS back? I think that Jelly Bean is just great on this tablet (at least with a custom rom). I upgrated and I never looked back lol

NVFlash!
I should have said this is in reply to geldebanho
Sorry for the confusion..

To be honest, I did not necessarily want to go back to ICS, but I didn't like the thought that I couldn't. Rebellious human nature... . I flash between GB and ICS on my phone on a daily basis.

[Guide] TF300 JB downgrade to TF700 ICS to gain ROOT access.

Warning: So far it's a one way trip to ICS, cannot return to JB. If it bricks your tablet, I'm not responsible for any damage.
There are two ways to flash an official update file.
1) Extract the .zip within the downloaded .zip file and place it in internal root directory.
2) Extract the .zip within the downloaded .zip file and place it in sdcard root directory and rename it EP201_768_SDUPDATE.zip
If you use method 1, you'll see an notification in the notification bar prompting or upgrade/downgrade. If you don't, try rebooting it. If it still doesn't show up, try method 2.
If you use method 2, you'll have to reboot into bootloader, selecting RCK with volume up button and it'll flash.
To downgrade into TF700's ICS rom, make sure you are on the latest 10.4.2.18 for TF300. Next, downgrade to 10.4.2.9 (can be found in TF300's forum) using either method 1 or method 2. Next, you downgrade into 9.4.5.30 (can be found in TF700's forum) using either method 1 or method 2 again.
If you happen to have flashed the wrong file, don't worry, it doesn't brick. It'll simply have an error of "signature mismatch" and restart (however your tablet would have been reset by this point).
After it's in 9.4.5.30 you can use the 1-Click-Root method that can be found in TF300's forum and gain root access.
My original goal to downgrade to ICS is hoping that I can spoof the MAC address to fool the unlock tool and allow me to unlock (I know my MAC address that is on ASUS's server file, which is different than what it is on my tablet), however that is not working out...
I have not been able to flash back to any of TF300's JB rom or TF700's JB rom after getting into the 9.4.5.30 ICS rom. I keep getting the following error...
Installing update...
Finding update package...
Opening update package...
E:resource mismatch, it's not mdpi!
E:check resource fail
SD Installation aborted
So right now I'm currently stuck on TF700's ICS rom.
I don't know if any of this is helpful to people. If it is to you, good for you. If you know how to fix the problem for me, let me know too, thanks.

Did you try to replace the build.prop file from TF300 ICS and try flashing the TF300 or TF700 JB ROMs?

Unfortunately, I don't believe this will help with allowing the generation of NVFlash files if you manage to get the TF300 to the TF700 9.4.5.30 ROM. NVFlash doesn't appear to work with 9.4.5.30 either. 9.4.5.30 most likely has the bootloader signature required by the JB bootloader, but thus prevents using the androidroot.mobi NVFlash one.
But maybe this can help people root without unlocking if there is a way back to the TF300 stock updates.

well I tried and replaced the build.prop
with TF300's ICS one... now it won't start at all anymore lol.

Think you have to push ICS of TF700 to Internal memory via ADB and reflash.
That should bring your tablet back. I would wait for senior members to comment to avoid mucking up further

Don't know if that was that good of an idea. The older devices of the tf300t have ics bootloader so they of course can achieve nvflash - but the newer devices didn't only get fixes in software I assume.
Read about ghost touches and so on which apparently doesn't happen on the newer devices.
Just get anyone you know to sign this petition so Asus might give us poor devils stuck on jb a chance to achieve nvflash

You are obviously getting an assert error when you try to allow stock recovery to install 10.4.2.9. Have you considered removing the assert and trying to install 10.4.2.9?

News? Did you try to update from tf700 ics to tf300t jb trought fastboot?

Official Blob files released. As well as new 4.2 unlock tool

Just so everyone is aware, i know this may be a pointless thread but i just want people to know that Asus released a new version of their unlocking apk tool on their website. This version is for 4.2 only.
They also released the official .blob files for Android 4.2

Do we need to unlock the bootloader again (?)
I think I'm going to try this, but I'm still afraid it will break my tablet...
I just hope we have a updated recovery soon

No just posted for people like Samsung.Galaxy.S3 who need to unlock their bootloader. Also posted because I feel like partition mapping has changed resulting in the failure on recovery. Also, TWRP believes the kernel just needs to be upgraded. One Asus releases 4.2 kernel source then I'm going to update and test TWRP builds.

Red triangle
Hi, I downloaded the Firmware from the asus website for my tf300t (ww version). I need to manually update it to 4.2 because my bootloader is unlocked. I'm with a stock rom and recovery.
I extracted it to the root of my internal memory and tried to update it (I turned off the device, pressed power+volume down and selected the first option).
It starts to update but after about 1 second the android with red triangle appears.
I'm doing it right or not? I'm sure that the firmware that I downloaded is the right one.

U sure its updating or just entering rck recovery. After putting the zip on root of sd or internal sd just reboot and after start up a triangle should apper in the notification bar then select the drop down menu and select it. In some cases people have had to rename the extracted update file. If us the name it to US_epad-user-10.6.1.8.zip if ww the capital WW where the US is.
