Guide to Root TF300T - JRO03C.US_epad-10.4.2.17-20121018

[jerry43812]

I'm more confused than ever on trying to find the *correct* guide to root my TF300T. The development forum has mislabeled threads, and most guides I found were guiding the root process for a device with a 9.x.x.x firmware. So, that said, can anyone point me to the CORRECT guide so I can root my TF running 10.4.2.17 please? Thanks.

So first off I totally understand the apprehension. I have rooted a lot thingd and this tablet seems especially technical and convoluted.

First read through this thread:

http://forum.xda-developers.com/showthread.php?t=1697227

1) In that thread download the "unlock bootloader" app, run it and unlock the bootloader. Your device warranty will now be void and it will say "device unlocked" in the top left corner every time you boot it up.

2) Now go to this thread, http://forum.xda-developers.com/showthread.php?t=1845377, scroll down to Part 3 and download the "fastboot + JB recovery" files. Extract them into the Fastboot folder that they are zipped in. There will be two .dll files, an ADB file, a Fastboot file and a twrp.blob file.

3) Turn off your tablet. Once it's off press the power and vol/dwn buttons at the same time. Keep holding them down until you see the screen with "RCK", "android", a usb symbol, and "wipe data". Once in that screen let go and use the Vol/dwn to move the cursor and vol/up to select the USB icon. Plug your tablet into your computer and the computer should recognize it as a "fastboot" device. You can check under "devices and printers".

4) Enter the "Fastboot" folder and while holding down shift, right click the mouse. In the menu you should have the option "open command window here". Select that and it will open a cmd window. Type in the line:

fastboot -i 0x0b05 flash recovery twrp.blob

This will copy the TWRP recovery file to the tablet and flash it. You will see a blue progress bar on your tablet while this is happening. Once that is done type:

fastboot -i 0x0b05 reboot

This will reboot your tablet and you will now have TWRP recovery installed.

5)Once in android again, go to this thread, http://forum.xda-developers.com/showthread.php?t=1668173, and download the "root-signed.zip" file in the second post and copy it to the tablet.

6)Turn off the tablet and boot into recovery by holding power and vol/dwn again. Once at the menu select "RCK" with Vol/up. It will boot into TWRP recovery now. Install the "root-signed.zip" file, reboot and the tablet should be rooted.

At this point I recommend creating a backup in recovery in case anything goes wrong from here on out.

Now you can flash any ROM your heart desires. I recommend CleanROM 2.7. It's fast, clean and very easy to install.

TWRP is easily the best recovery for this tablet. I have had many problems with CWM not installing ROM's properly and causing boot issues.

I hope this help you out. I know it's kind of a mine field of information but it works very nicely.

I was just about to link you to the same thing. This process will flash recovery and root your tablet.

1) In that thread download the "unlock bootloader" app, run it and unlock the bootloader. Your device warranty will now be void and it will say "device unlocked" in the top left corner every time you boot it up.

This is a relatively big deal: while you could root stock ICS ROMs pretty easily, you can't do it on stock JB ROMs without unlocking the bootloader, Once you're unlocked, however, it's a piece of cake.

For the amateurs. Could you elaborate on these steps?

Step (1) (a) which file to download? the .apk for the .exe file?
(b) Download to where (the tablet or onto a laptop/desktop)?

Step (2): (a) Again, download to where? Tablet or laptop/desktop? And extract to where?

Step (3) & (4): This make it sounds like the files in previous steps should be downloaded and extracted to a laptop/desktop?

Step (5) & (6): CleanRom 2.7 is already rooted. Do we need to run these steps? Or can we install CleanRom after Step 4?

Backup: What files to back up? Everything?


Critical Questions:

Do the above steps work for tablets already on Android version 4.1.1 with .29 (or .17) builds?

Sidenote: Last night, my tablets had an ASUS update and it went from build .29 to .17. Is this strange? It's going backward?

I have followed these instructions exactly, but titanium and adaway both cannot aquire root privileges. and reason why?

Download the .apk and put it on your tablet. Install it. Run it.

Step (2): (a) Again, download to where? Tablet or laptop/desktop? And extract to where?

These files are to be put on your computer. It doesn't matter where you put the directory.

Step (3) & (4): This make it sounds like the files in previous steps should be downloaded and extracted to a laptop/desktop?

Yes

Step (5) & (6): CleanRom 2.7 is already rooted. Do we need to run these steps? Or can we install CleanRom after Step 4?

These steps are not technically required but I put them in there because then you have a backup copy of stock JB that is rooted.

Backup: What files to back up? Everything?

Run TWRP. Press the back up button.

This method works for any version.

Have you confirmed that you are truly rooted or are these apps the only ones that can't access the root directory?

 

[smokarz]

So you have to root first in order to do a backup?

 

[Ramrod421]

No you do not have to root first to do a backup.

I would try and clear the cache and data for supersu under settings>apps and that might make it start working properly.

I read the reply's to your Q, but as I have the same build as you I still haven't found one that anyone claims has worked.

You have any success?

Root TF300T

Thank you so very much for that very helpful post. Much appreciated.

After reading your instructions, I'm happy to proceed but may I ask one question first.

I've unlocked my TF300 with the ASUS application.

My build number is 10.4.2.18-20121122. It's a UK model.

Am I safe to use your instructions with this build?

Kind regards

 

[jerry43812]

I never obtained root, and since my OP, I've gotten an OTA as well, so it's back to square one in finding a viable root method.

I'm in the same boat. Got a 300 for Christmas, bumped up to JB w/o reading here first (yeah...that was dumb). So from looking around the only way to root is to unlock and the only way to unlock right now is via the ASUS tool which - from what I've gathered - will send my serial number to ASUS and void my warranty correct?

A few questions:
1.) does anyone know if work is being done to be able to unlock/relock w/o voiding the warranty? I love root, but I won't do it while in warranty in case something unthinkable happens . I'm not sure how much of this would be true, but can't we use nvflash to download the locked bootloader then find a way to spoof the ASUS unlock authorization? Hell, unless each tablet uses a different signature couldn't we just post the nvflash-able locked/unlocked bootloaders? I'm thinking back to the flash processes from my Tegra2 gTablet. I could be way off base, but it seems plausible with my limited knowledge.

2.) is it possible to root w/o unlocking? I know I won't get CWM/TWRP and the ability to load non-stock ROMs but I can live with that. I'd like to be able to run TiB, ES File - Root, etc though. I thought I saw something about obtaining root w/o unlock, but I can't find it and it might have been ICS instructions.

3.) I take it there's no downgrading back to ICS that would fix this either....

Hi!

You can try to unlock your device with AsusUnlock app ! - is the safe way to unlock bootloader ! ( certainly will void your warranty ! )

I don't think that's cause for concern ...I've unlocked bootloader in the very next day after I bought it ( in august this year )

- so far I think I made five hundred " flash and reflash rom " - ( for testing "custom roms" ) - and the device shows like the first day when I bought it

So, be more confident - the device is not so easily to break , you can install as many "custom roms" as you want - you just have to be very careful about the steps that you make - when you try to install a custom rom !

Good luck ! :good:

regards,
Surdu Petru

Not worried so much about flashing causing issues. I've flashed my gTab more times than I can count. More worried about pre-voiding the warranty should I have any hardware issues. Like my battery life seems to be horrible and it might need sent in for that.
