Can TF300 running JB be rooted?

After having spent a week or so to play with this new toy, I am more inclined to root it. But it seems all the rooting methods are for pre JB, do I miss anything? Can I root it while retaining the locked BL?

To my knowledge, a means has not been found yet. I'm wanting that too.

Yep, add me to the wait list. Someone will figure it out. It's a challenge

Not possible to root stock jb as of now without unlocking.

You can downgrade to .30, root, and then upgrade to JB

I apologize in advance for the noob question, figured this is prob the best thread to ask...
Im locked, stock, and (two smoking) JB... (sorry for the bad movie joke)...
i was reading the "noobproof upgrade to JB, recovery +root" thread and im having trouble understanding it completely. do i have to go to the Asus site and unlock my bootloader first? and from there, where it says to DL the files, do i DL them to the tablet? because this is confusing me:
2) Extract the recovery with fastboot files zip and open a command prompt in the same folder of the adb and fastboot files (Shift + Right mouse)
3) Reboot into the bootloader of your tablet, type: adb reboot bootloader
"open a command prompt in the same folder of the adb and fastboot files (Shift + Right mouse)" am i doing this on the tablet? if so, how do i open the command prompt? shift+right click doesnt sound like something i can do on the tablet, is it? and once i open it, i just type in the "adb reboot bootloader" ?
again, sorry for the noob Qs, this is all alot easier on my phone

i don't really know how to root but for unlock bootloader , you just simply go to asus website(as you said) and download Asus unlock bootloader application . This is .apk file so you can directly download by using your tf300, then install that application. open it and following its instruction.

Download the attached and copy to your device storage. Install it like any application. Open it and follow its instructions and let the device reboot itself to unlock automatically.

Fastboot not working anymore?

Hi all.
I went to update my Recovery today to a new TWRP.
I have not had problems in the past.
When I boot into fastboot it just says "Starting Fastboot USB download protocol".
The drivers are properly installed and made sure under device manager.
Any idea's guys?
When I type fastboot devices I don't get anything.
Thanks for the help!

Also tried in Ubuntu still no luck >_<

Let's talk about ubuntu a minute since fastboot worked before. It appears no one else has said fastboot worked earlier.
Are you running ubuntu on a different computer?
Same computer through virtualbox or something similar?
Same computer different drive or partition?
Try " adb devices " before you reply and include that info as well.
I should have also asked if fastboot previously worked on ubuntu?

the problem is not the computer itself, the real problem is that the tablet doesn't get in fastboot mode...

Thank you for the update.

Try this:
-use unlock tool
-boot tablet into USB MODE
(it will say fastboot mode,waiting)
-using the steps,copying over the fastboot files to one folder, with TWRP as the recovery, run fastboot command.
-done successfully,you be good

I'm not the author of this process, but apparently it works.
I haven't tried, because I use terminal emulator for my adb command

no way, i can't get it to fastboot damn it
---------- Post added at 11:45 PM ---------- Previous post was at 11:16 PM ----------
ok i solved the problem just now...
1-reboot the tablet in bootloader while connected to usb
2-use vol down to navigate to the usb mode and then vol up
3-the tablet won't show nothing but actually it is connected
4-proceed to any fastboot command
hope this helps

I had this issue when I first started flashing stuff (although I was flashing CWM not TWRP)
In my experience, if you don't see anything listed in fastboot devices, it doesn't matter because it still flashes.
Just try using the flash command (fastboot -i 0x0b05 flash blah blah blah.blah) and see if it works.
You -should- be able to see your device in "adb devices", and that's really what matters.
Also, what matt95 said is exactly what I do. Whether it shows anything or not, I just flash my stuff. Works fine, but I also don't use fastboot alot because with the new changes to the bootloader, one can flash stock through CWM now without having to fastboot flash it.

I'm having the same problem here with fast boot. I want to run NV Flash so I can update to the JB bootloader for CM updates. I've tried simple commands like reboot and nothing works. Any other thoughts?

I'm in the same wagon as all you guys, I just tried that and I can't get into fastboot still. Still waiting for device
---------- Post added at 01:10 PM ---------- Previous post was at 01:02 PM ----------
I'm sorted now, I didn't realise that we needed a different command
I was using
Code:
fastboot flash recovery recovery-jb-touch.img
instead of the correct method of using
Code:
fastboot -i 0x0B05 flash recovery recovery-jb-touch.img
This worked perfectly

it's same as this:
== Part 3 - Install recovery and rooting ==
Let's start with installing the recovery
1) Download these 2 files:
- Jellybean recovery with fastboot files: Fastboot files + JB recovery
- Root files => Root files
- You can also download the new CWM Touch recovery if you don't like TWRP: CWM Touch recovery thread or TWRP recovery and download this file : openrecovery-twrp-2.3.1.0-tf300t-JB.blob
2) Extract the recovery with fastboot files zip and open a command prompt in the same folder of the adb and fastboot files (Shift + Right mouse)
3) Reboot into the bootloader of your tablet, type: adb reboot bootloader
4) When your tablet has reached the bootloader navigate with volume down to the usb icon and press volume up to confirm.
5) To flash the recovery type:
- TWRP: fastboot -i 0x0b05 flash recovery twrp.blob
- CWM: fastboot -i 0x0b05 flash recovery CWM-Touch.blob
6) A blue bar will appear and the recovery will be installed, when the blue bar is filled press volume up + power button to reboot into the tablet.
Now we will root the tablet
7) Copy Superuser-3.2-RC3-arm-signed to the internal storage of your tablet. then reboot into the bootloader again.
8) This time you need to select the RCK icon with volume up to enter the recovery image.
9) In recovery flash Superuser-3.2-RC3-arm-signed and reboot into the system
10) Install Supersu from Google Play
11) Open up Supersu, it will ask you to update the binary, choose yes.
12) Now your tablet should be rooted

[Q] Asus TF300T Does Not Start Because Of The Clockwork Recovery

Tablet: ASUS TF300T, Unlocked.
SO: Cyanogen 10
Old (working) Recovery ROM: “recovery-jb.img”
New (NOT working) Recovery ROM: “recovery-clockwork-5.5.0.4-tf300t.img”
Keys combination don’t work, just the APX one.
Symptom: the cyanogen didn’t work well so I changed the recovery ROM. As the new Recovery locks when executing from the bootloader, I decided to restart in recovery directly from the cyanogen (power button –>Reset -> Reset into Recovery). VERY BAD IDEA: Now the tablet always tries to start in recovery and gets stuck on the start screen. I can only enter the APX with keys combination. I cant enter boot loader and ATX doesn’t recognize fastboot & adb instructions.

Hi, I believe cyanogen 10 uses a jellybean bootloader and CWM 5.5.0.4 is for an ICS bootloader, so you will need to flash CWM 6.0.2.3 which is for jellybean bootloader.
Have a look at link below and download 'recovery-jb.img' & follow the how to flash.

I think it goes into APX mode, holding "vol +", the screen remains off but the USB recognizes the APX. What should I do at this point to re install the ROM CWM or enter bootloader? when I go out the APX mode all remains the same, the tablet is still stuck .

Ok I no expert here so anyone else please correct me if I'm wrong.
When you say the USB recognizes APK, do you mean (assuming your running windows) that you can see your tab in device manager - something like 'Asus Android Device - Asus Android Bootloader Interface'
If so try this, open cmd (I always run as admin, don't know if it makes a difference) navigate to your /android-sdk/platform-tools and type
'fastboot -i 0x0B05 device' and hopefully you will get a response about your device (tab). If you do I would assume you could then flash recovery, ie put recovery-jb.img in your platform-tools folder and in cmd type 'fastboot -i 0x0B05 flash recovery recovery-jb.img' once done type 'fastboot -i 0x0B05 reboot' and hopefully all will be good, you may then need to reflash you rom not sure.
If your tab does not show in device manager then I have no idea sorry.
Hope this helps.

Hi! thx for your help. fastboot and adb don't recognize the tablet in APX mode. My PC recognize APX mode. I installed the drivers for APX and I have nvflash ready to work, but it seems to be useless without access to fastboot.

You have to wait for NVflash for JB bootloader.

Hi, sorry to say after alot of searching and reading looks like the only soluation is to send it to Asus for repair.

[Q] locked, rooted, can I install twrp?

I purchased a tf300t that was at 9.4.3.17 so I ran the 1 touch root and got root, then installed root keeper. Ithen let it update to 10.4.2.20 and then ran root keeper and restored root. I can run titanium backup and do get the superuser request all seems well. But I can not seem to be able to flash recovery. I tried using both twrp and cwm blobs and both seem to work but when boot to recovery I get the android on his back with chest open. I tried to install it using the fastboot and the terminal method and both look like it has worked but then doesnt when i try to load recovery. Am I doing it wrong or will this just not work without being unlocked? I dont really want to unlock it yet due to some dead pixels I am debating on exchanging it, but fear I might end up with one that has jellybean preloaded.

No you cannot. Flashing any recovery requires fast boot. Which requires unlocking theboot loader

I am able to select USB at the bootloader and use fastboot I think? I typed the fastboot -i 0x0B05 flash recovery twrp.blob command and it does show the blue bar with it transferring the file, is there more that isn't happening?

Then you are unlocked.. I dont even think the USB is an option on locked bootloaders. I may be wrong as i havent really used my device before unlocking

If I may, even while locked you can select the USB icon and use fastboot. Type fastboot devices on your PC to confirm it works, but if you try to flash anything like recovery, and you are still locked, you will get a status 7 error. It will not flash. You must unlock for that.

Fastboot CWM/ Root Help needed

I have been trying to put cwm on the tf300t for about two days now reading everything and still got no where. The device is unlocked i used asus apk to unlock it. every time i do the power and down step i do not have the usb option just rck, cold start, wipe data. i cant do anything with fast boot to put cwm onto the tablet. any help would be appreciated. i tried reinstalling fast boot and reseting the tablet. i am on 4.2.1

Which guide are you using? The 4.2 bootloader automatically connects in fastboot mode as far as I know when you get into the bootloader menu which is why the USB icon isn't there. You should be able to use fastboot commands whilst in the bootloader menu

I did read that somewhere and i tried running the recovery through fastboot but it just says waiting and does nothing. I also noticed when i plug it into the computer it says fastboot on the usb but it has a little symbol next to it as if it wasnt running right,but i have reinstalled it a few times

AFAIK, there is no version of CWM compatible with the 4.2 bootloader. You'll need to use the TWRP versions that end with -42.

I have tried installing TWRP running command "fastboot -i 0x0B05 flash recovery twrp.blob" still no luck just says waiting for device and the tablet stays at the rck screen
