Need help rooting and/or flashing twrp - Transformer TF300T Q&A, Help & Troubleshooting

Hello everyone!
I need some help rooting my tf300t, because what I've read here and there was somewhat useless, since everyone sais different stuff. For first I'd like to ask for your help in clarifying which one is first. I have read guides in which rooting was first than pushing the recovery, and I have read ones in which fasbooting recovery was the first thing to do, and than flashing su. I have tried both methods, with no luck. When I try to fastboot twrp onto my device, it sais 'waiting for device'. I read that this means fastboot is not properly configured, but I am an administrator on my PC and I have the proper drivers, since adb reboot-bootloader works. So thats for flashing twrp first. Then rooting first. I tried with motochopper, but that does no work on 10.6.1.27.5. So I tried pushing root files manually, but when adb shell /data/local/temp, it sais failure. So if you could help me, of what did I do wrong, I'd greatly appreciate it.

First make sure that you have unlocked your bootloader (text in the upper right corner of boot screen). What I did first was flash TWRP from ADB. In your case, you would flash the stock ROM, and then flash SU.

I know I'm unlocked sorry for not mentioning that, though even that was strange, because the unlock device app should have wiped the memory, but it didn't, and still unlocked. But I don't exactly understand what you mean by flashing the stock ROM, then SU. And if you mean that do that with twrp, I can't because fastboot flash recovery twrp.blob just waits for device. Is there another method which I can flash it with? Thanks in advance

If it says "waiting for device," your PC is not communicating with the tab. What Windows version do you use? Does "fastboot device" command from fastboot mode on tab return any serial number? It should show a serial number before you can flash TWRP onto the tab. And where did you read that unlocking the device would wipe the memory?
Get fastboot to work first, then you can flash whatever. Otherwise, if you're on stock recovery, try loading the rom zip file onto your sd card and flash it using RCK option. If you have no idea what I'm talking about, read first, so you don't brick your tab just because you have no idea what the heck you're doing.

For first, I downgraded my device, so I could root it with motochopper. Then I flashed recovery with the way explained here:http://forum.xda-developers.com/showthread.php?t=1845377
Now twrp seems to be working, i can start it, but it cant mount anything, so i cant flash anything from the device. Both 2.5 and 2.4.4 does this. Goo manager cant find a recovery for this device, so i cant use that either. Fastboot still cant see my tab. Im on windows 7, with proper drivers

Nevermind my stupidity, I installed the wrong recovery, not the one for the 4.2 bootloader. By now I'm a proud owner of a tf300t with cyanogenmod on it Thank you both though, for trying to help

[Solved]

SOLVED!!
Hey guys, i've seemed to set myself up for a soft brick upon me not reading everything clearly and correctly.
I was trying to take an easy route and simply misread a few numbers.
I really need help here, I unlocked my bootloader then proceeded to use a 1 click root solution from here; http://android.modaco.com/topic/327000-08-aug-grj22-colour-revert-superboot-rooting-the-nexus-s/
I just went back to stock after wanting to start clean when I got this phone, anyway I didn't see that this was intended for 2.3 where as my phone was running 2.3.4 and thats where I think I went wrong.
I can access bootloader, after trying this method the phone just boots and hangs at the unlock screen and nothing else. I don't have recovery so I can't get into that, I tried locking and unlocking the bootloader to see if that would help but no luck.
Where do I go from here?
**at&t model
If you can access the bootloader, you're fine. Just install ADB on your computer and flash a custom recovery image. From there, you can flash a ROM.

the very last part about unlocking the bootloader
and it just keeps giving me that error
Okay, been awhile since I did the whole unlocking bootloader/flashing recovery thing. If I remember correctly, in the command prompt, you should navigate to fastboot which is located in <whatever you named your Android SDK folder>/platform-tools folder. Also, place your recovery image in the same folder. Then enter the command from the tutorial. "fastboot flash recovery <image recovery file name>"
sent you a PM
a huge thanks to deejaylobo for helping me out, a folder wasnt renamed so I had a hard time pushing recovery but he got me back on my feet!
thanks again!!

[Q] stuck in boot loop / pc not recognizing phone with adb

Hi,
I tried to install a ROM but it got stuck on the white screen with the HTC logo. I tried to do factory reset but it gets stuck again. I don't have clockwork recovery, and I rooted my phone using adb and ace recovery, which is not on my phone. I only temporarily used it to flash my rom, stupid I know. :-/ When I connect my phone to the PC it is not being recognized. I tried putting the PD98IMG.zip file on my sd card but it just says that it the image is incorrect. Is there anything I can do? Is this fixable?

I just went through some similar stuff. What type of computer are you using? PC/Mac? Are you using the original cable? What troubleshooting steps for connectivity have you done? Different cable? USB port?
Can you access the bootloader screen when you pull the battery and reboot while holding the volume button down and holding the power button? By accident, I found that the phone and PC will communicate with each other when "Fastboot" is selected on the bootloader screen (you should hear a connection chime and it should change to "Fastboot USB") except I could only get fastboot commands to work. The good news is that should be enough to flash a boot or whatever else you need to get back in business.

Hi, Thanks for the reply.I am using windows 7. I downloaded the drivers for HTC, and I am using a data cable and the USB port in the back of my computer, nearest the mother board. I do see "Fastboot USB" on the phone but when i type in the command prompt "adb devices" I get nothing.

That's great you're getting the fastboot usb message! As long as you're not using a hub or some other usb extender, any functioning usb port on the pc will do. Again, I learned this by accident (ie the hard way) and found that in this mode, only fastboot commands will work, not adb. (on a side note, and others should correct me here, adb and fastboot work together when the phone is rebooted normally or in recovery but not in the bootloader screen)
Great test for connection: fastboot devices (if you get anything else except a serial # with fastboot after it, then close the cmd window, unplug, and pull battery/reboot to bootloader), fastboot reboot-bootloader. Once it reboots back into the bootloader screen, make sure you press the power button while fastboot is selected and you should again hear the chime and see fastboot usb come up. This is your phone saying it's ready to accept your fastboot commands.
Do let us know how it works.

As far as I know, fastboot only works when your phone is in fastboot mode. ADB works in recovery or system.

Flash a rooted stock ROM from recovery. Whether you have root is in your system partition. Whether your bootloader is unlocked is in your bootloader. Whether you have a custom recovery is in your recovery partition. Three separate things.

I'm guessing that you're trying to flash a PD98IMG.zip or a RUU. You need an actual stock rooted ROM, probably from here on the forum. Or just flash Android Revolution HD, an optimized rooted stock ROM, also from here on the forum in the development section. For more specific steps read the Ace Think Tank linked in my signature.

Dear friends,
I have this problem: I got a brand new TCL S720 and the Google Play did not work, being a known rom issue. So, before doing anything, I've managed to make a backup of it's original rom with MTK Droid tools whichI supose it did it well. Then I've tried to install a CWM recovery to try a custom rom for it. The CWM recovery seemed to install succesfully but I didn't manage to install the new rom. If I remember well, it stucked on boot logo. Then tried to revert at it's original stock recovery, managed to have the phone back as it was in initial state, but doing more tries, It remained stucked on boot logo. The problem is that my computer doesn't recognise it anymore, when I connect it to USB it tries to install MTP usb driver but even before the driver was installed well, now it refuse to install, like the driver is not good or the proper driver doesn't exist. So the only thing I can do is to boot on stock recovery but even I tried to copy the original rom update.zip on external SD and to flash the phone using install update from sd card in recovery mode, It doesn't find the external sd card. So I'm stuck here, the computer doesn't detect the phone to try flashing it with SP flash tool or MTK Droid tool, and I also can't flash it from sd card. Have you any idea how to make it work again?
Thanks in advance.

[Q] [noob] Multi-problems 4ext, CWM, superuser - Advice?

I'm posting this in a single thread to minimize clutter.
I recently ran Easy Ace Root tool as instructed on my inspire. The bootloader unlocked, CWM flashed, but there was an error during superuser flash.
After a reflash of superuser things looked okay, but superuser began not responding. I re-flashed superuser twice in attempt to fix it using the Easy Ace Root Tool.
EDIT: I have discovered that superuser will only function with "USB debug mode" enabled. I've tried it on and off several times, and each time it malfunctions but function returns without a problem.
The backup I have been restoring seems to work because it was created with the debug mode enabled. Took a while to see it.
Second, CWM started to exhibit the "power off, charge" recovery bug where CWM opens.
Last, I attempted to install/flash 4ext Recovery Touch twice to address the CWM bug. Both times it hung at "flashing recovery" (approx 20 mins. both times). Eventually, it indicated that 4ext was installed. However, booting into recovery shows that I still have CWM. I used two different versions (RC8 & RC 7) in the attempt.
I'm now using the restored and working ROM. Solutions to the superuser debug issue I haven't seen posted
The failure to flash 4ext is troubling.
Questions
1. Could these issues be related? Or, what should I be looking for?
2. The recovery issue seems to be the most important. What might be the cause of 4ext to fail in this manner?
3. Can the Easy Ace Root Tool be rerun on the unlocked bootloader, and would that fix anything?
4. Is there reason to worry about flashing with CWM?
I see a number of possible solutions, the main one is to flash a new ROM, which I have already downloaded a couple, but doesn't adress the recovery problems.
The issue with CWM and 4ext leave me less than confident in using it to flash with, although CWM seems okay. The other item is that some ROMs indicate that S-off in required, but many of the threads are a couple years old.
5. Is it correct that S-off is not required to flash ROMs (I read it somewhere)?
I found an answer: NO, YOU DON'T NEED S-OFF TO FLASH ROMS....
Solving the issues are good lessons
Stock AT&T ROM
Android 2.3.5, Sense 3.0
Bootloader screen indicates-
UNLOCKED
S_ON
I know that's a lot for one thread but I'm just looking for a direction and I'll do the search.
If anyone has suggestions, directions, or ideas fire away.
Thanks
I think the fact that you are still S-ON is causing problems with the recovery flashing, since S-ON basically means that the recovery partition is not-writeable.
Have you tried using fastboot to flash a new recovery? Plug your phone into a computer, get into the bootloader, select "fastboot" (if not already selected), wait for "FASTBOOT USB" to appear, and then run the following on the computer:
Code:
fastboot flash recovery <path to recovery.img>
However that S-ON still worries me. You might have to do things manually:

Thanks, I think you meant to say the fact that I am still S-ON? The S_ON part shouldn't be an issue from all that I've gathered. In fact, that's how I have CWM. The Easy Ace Root Tool does CWM, with an unlocked bootloader S_ON. Nothing I have come across states that S_OFF is required to flash 4ext recovery.
Other noobs might find this other thread useful as there is some info and links to recovery images. http://forum.xda-developers.com/showthread.php?p=22489317#post22489317
No I haven't tried the fastboot yet. That is an option, I've got it and adb setup on my computer already. I have looked at AAHK, but as it says its no longer supported, and I don't think I need of S_OFF. Taking it slow to sort out the problems so I don't do sumthin stooopid.
How are you flashing 4ext? From fastboot?
Right, S-ON, that's what I get for writing this at 12 AM.
Don't bother with AAHK, it's discontinued, and even if you still had a copy it couldn't download the necessary files.

bananagranola,
I used the 4Ext Recovery Updater for both attempts. As I said in the OP, both attempts hung at "flashing recovery" approx 20 mins, and eventually indicated that 4ext was installed. In Recovery Updater it listed/highlighted the version I thought I had installed, but CWM was still the recovery that booted.

Yes, those instructions will work. If you can't boot into fastboot through the GUI, you can also power on the phone while holding the volume down button, and that will get you into the bootloader.

Probably. But I don't think it really matters, since if you can flash a recovery using fastboot, you can do everything that 4ext updater otherwise would.

See above.
If 4ext doesn't work, you can also try CWM and TWRP (TeamWin Recovery Project). I use the latter with my Inspire 4g.
I strongly advise you use the app to download the recovery, unzip, and then flash it from fastboot.

I'll take "strongly" as more than a suggestion. Thanks, it had not occurred to me to get the recovery.img from the updater.
I had actually found several other images and was trying to figure out what was what. That saved me some time, but I did read a lot about 4ext.
I was considering trying the Recovery Updater one more time. Bad Idea?

Solved the 4EXT flashing issue. Looks like 4ext flashed okay with fastboot, and the 4EXT Recovery Control works. Rebooted into recovery a couple times just to be sure. That kills 2 birds the CWM bug and the recovery flash.
Thanks for the help and suggestions all.
Some notes from a noobs experience -
Setting up ADB and Fastboot is very easy.
If your cautious as I am run some basic commands in ADB and Fastboot that won't do damage [devices, reboot, reboot-bootloader, etc.]
If you get "error: cannot load 'recovery.img" make sure you navigate to folder that recovery.img is located. Then run "Fastboot flash recovery [Filename]." Even though I set system variables on my desktop to point to adb and fastboot, it won't find the recovery image if you start from the wrong directory in terminal (i.e., C:\)
If you're in ADB and you use the command "adb reboot-bootloader" it will boot the device straight to "Fastboot USB".
Don't forget that each time you flash a ROM from recovery, you still need to fastboot flash its boot.img separately.

Thanks for the reminder. I just spent an hour looking at 4EXT "smartflash no available". I hav some links for doing fastboot flash of the boot.img. I think I'm good there.
One question from my OP remains. Superuser only works (i.e., grants root access) when I have USB debug mode selected. When it's off superuser says the app (e.g., Titanium BU) is granted permission but just hangs until I force close it and re-enable USB debug. i can't find anything on this problem.
Is it an issue to run my phone in USB debug mode all the time? Or, any clue to the problem?

TF300T 4.2 TWRP Error

Hi XDA,
I am a complete noob, and this is my first time posting, so bear with me.
Some time ago I rooted and unlocked my TF300 with SuperSu. Recently I wanted to upgrade to 4.4 kitkat. However, my Tablet was stuck at Andriod 4.1 because of the the unlock.
I went to manually update my TF via the Asus website. I installed the 10.6.1.8 using my TWRP 2.5, and Oem 4.1 OS. Installation worked just fine. After install, I booted up and I had 4.2 with everything working correctly.
Next step was to install TWRP 2.7.0.1. I reset my TF and went into RCK to see something went wrong when updating.
My TWRP will not load, and I get the Android on his back with the red triangle when I try to enter RCK.
Thanks in advance!!
I managed to install 10.6.1.27, but it did not change anything with my boot loader.
I downloaded motochopper, but that didn't seem to work, just told me my abt was out of date. SuperSu isn't working now either, "No Binary, There is a problem."
How do I install TWRP 2.7 with no boot loader? Please help.

Most people just install TWRP via fastboot like
Code:
fastboot -i 0x0B05 flash recovery twrp.blob
You could try using other root methods, like Framaroot or Kingo. I think Kingo was reported to work on the latest stock version.

I will look into that, but I am pretty sure I was already rooted, unless losing my boot loader means I am no longer rooted.
Another thing, I can't find a twrp.blob for 2.7, just a zip. I have one for 2.5, but that is useless because I already have 4.2. I also have not been able to find a working link to fastboot.
If anyone could give me a link to the fastboot or a link to a tutorial, that would be amazing. I have done my research, but all the lingo and different methods can be mind bending.
Thanks

You can get the img (which substitutes as a blob) from extracting it from the TWRP 2.7 zip file.
1) You will need ADB and fastboot for this: http://forum.xda-developers.com/showthread.php?p=42407269. I would suggest keeping the tablet at least at 50% battery.
2) Install Naked Drivers. This may be optional for you. If you can proceed to the next step without, you won't need it.
3) Enter fastboot by rebooting and holding down the power button. TF300 enters fastboot automatically since this is 4.2 BL.
4) Next we need to enter a command. In side the ADB folder, hold shift and right click. Then select Open command window here.
first check to make sure the device is connected:
Code:
fastboot devices
The device serial number should be listed.
enter command:
Code:
fastboot flash recovery twrp.img -i 0x0b05
Blue bar on device will fill. Be patient.
5) Reboot the Device back into Android. This is an important step.
6.) Go back into TWRP and install what you want.
You are amazing. I will give it a try tonight and report back!

Installed adb fastboot. However, my device does not automatically go into fastboot, I still have to hold down the volume key.
Once I am in fastboot usb (with the 3 icons), I fastboot successfully and get the serial number, then when I type the 'fastboot flash recovery twrp.img -i 0x0b05' command I get this error: cannot load 'twrp.img' : No error
I am attemping to use the 2.7.0.1 twrp from the 4.4.2 page. I have extracted the recovery.img (tried renaming to twrp and left it the same) and placed it in the root of both my external and internal sd.
I have now tried it with .zips .img .blob and I receive the same error everytime. Not sure what I am doing wrong now.

Put the twrp.img into your ADB folder, where you installed it. Then run the next command.

Awesome! Worked like a charm. twrp 2.7.0.1 installed perfectly.
Then I tried to flash the cyanogenmod. Said it installed fine, but it just gets stuck on the loading screen...
I am trying to do exactly what TallMilk is doing...put Cyanogenmod on my tablet. It is my understanding that I have to unlock my bootloader though? Which I have tried doing a million different ways with the Asus Unlock tool which always gives me an error.
If I follow the instructions posted above I will be able to flash Cyanogenmod without unlocking my bootloader?

Finally got it to work. I had to do a wipe first, read about old roms interfering with new installations.
SilentSpartan, I used SuperSU last year to root and unlock my tablet when it was still a 4.0 android to flash to 4.1. This recent update was from 2.5 TWRP on a rooted device running 4.2. When I installed 4.2, it blew away my TWRP, and I had to flash the new TWRP 2.7.0.1.
That flash from OEM fastboot to TWRP 2.7.0.1 is what I needed help with.

You're going to have to unlock no matter what. Did you try both v7 and v8 of the unlocker and calling Asus Support to tell them to put your serial number back into the database (get a manager)?

I've tried every firmware and unlock tool combination. Nothing works. I sent them an email a day ago. Depending on there response, maybe I'll try calling. I'm so fed up with this tablet, I'm about to throw it out my window. $400 POS. :good:

Did you ever get your tablet fixed? I am having some problems myself after a miserable m9 update.

Soft bricked shield tablet PLEASE HELP!

So I bought my shield tablet back in March, used it until about may I think. Was browsing the internet then it suddenly crashed and got stuck on the Nvidia boot screen. tried to reboot several times. Nothing. So I forgot about it and thought I would just google the reset option later when I had time. Now since June I have tried everything! From factory reset to fast boot and adb my pc won't even recognize my tablet. Also I never turned on usb dbugging cause I didn't even know what that was. I even gave it to the IT guys at work and they couldn't fix it. Now after reading everything there is to read on this problem and trying to fix it myself I'm stuck on the no command screen with the dead android robot. And now I hear there is a recall do to the battery, I can't even check what type I have. So if someone can please help me I would be much appreciative. Also this happened after updating to the latest OS.
okay so i was able to unlock the bootloader and start flashing but from fastboot flash recovery.img and beyond it says failed to write. any ideas of why?

Hello,
Did you use "Fastboot flash recovery.img" as your command line??
I believe it is "Fastboot flash recovery recovery.img"
If you were able to unlock bootloader you're on the right track.

Yes I used "fastboot flash recovery recovery.img" but every command after that keeps telling me "failed to write file"

TWRP (Team Win Recovery Project) is a custom recovery that you can flash on your device. You can flash it like the stock recovery over fastboot. With TWRP you can make full system backups, installing roms or other stuff, wipe partitions and more. Keep trying to install the drivers on your pc. Try to use another usb slot or boot your pc into test mode to install the driver. If you can still access the bootloader, you have really good chances to rescue your device.
Okay will try that. Thanks man.

I see what your doing wrong. You probably don't even have the recovery img to flash. That's why it's giving you a write error.
There is a tutorial in the general section, that should have all the files and links, etc etc that you'll need to flash TWRP/CWM recovery and root the device if you want

If your referring to the recovery images from Nvidia website I have dowloaded that, also the correct drivers. Maybe there is something else I'm missing?

First off, let me ask, what is your end result for the tablet?? Are you trying to just go a Complete stock tablet or are you trying to do anything custom (ex. Custom rom, recovery etc etc)
I'm assuming that since you unlocked your Bootloader, your trying to do something custom.

Those official nVidia recovery images come with smaller .img files such as recovery.img, system.img, etc. You'll need to flash those one by one ("fastboot flash recovery recovery.img", then run "fastboot flash system system.img", etc. etc.) or you can just run the flashall script that I think is included in the nVidia images.
Otherwise, if you want to flash TWRP, you'll need to download the TWRP recovery (you can rename it to "twrp-recovery.zip"). Then you'll need to "fastboot flash twrp-recovery.zip" in order to flash the twrp recovery to your tablet.

OK. Then the link I gave earlier should help flash stock software onto your tablet.
However, that guide is only to go back to factory "state" Operating System wise. It may not help with hardware. Once your flash everything correctly but device still doesn't boot, its probably not software related.

After you unlocked the device but before trying to flash anything else on the device, try putting the shield into Fastboot mode. At the bootloader, select fastboot using the volume buttons.

So i selected "fastboot protocol" it blipped for a second then brought me back to the bootloader. tried flashing again and once i reached the fastboot flash system system.img it said write failed again. did it not engage the "fastboot protocol"?
Bringing you back to the bootloader was expected behavior. The "write fail" is a mystery to me. Sorry, that is all that I can offer.
