The tablet is already in fastboot when you see RCK and the other options. If youlook above the options, you'll see 'starting fastboot usb download protocol' So you dont need to select the usb icon to enter fastboot.

Ok, thanks.... However one other thing I noticed there is also a message that says key driver not found booting Os. Is that important?

I read about it that it's not important. i also see that on my tablet too. i've flash my tablet more that 20 times without any problems. SO dont worry about it.

I have the same problem on my tablet; the point is:
if it is already in fastboot mode, how can i install clockworck mode recovery or install a new rom?
Beside, I've noticed that when i plug it into the pc, open a terminal (in ubuntu) and type "fastboot device", the pc does not recognize it and just displays on the terminal this message "<waiting for device>;
what does it mean??

You need to install the Naked Universal Drivers to use ADB and Fastboot. Look for the device in device manager as well.

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.

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
I decided to automate the process of entering commands. Post

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] Killed Fastboot??

I tried GOOMANAGER but wasn't rooted and I think that might have screwed up my Fastboot possibly....when I try to do boot into recovery now and select the RCK option I get the dead / sick droid and it says error every time. I don't know what to do now! Any ideas? I also tried to downgrade from 10.6.1.14.10 to 10.6.1.14.8 so I can root and install TWRP and ROMS, but need to get into recovery to do that. I cannot get into Fastboot / recovery to load stuff!!! HELP!!!!!!!!

I've unlocked the bootloader and I wanted to root it. I'd like to put a custom recovery TWRP and custom ROM probably CM 10.1 or something like that. Currently I'm running stock ROM build JOP40D.US_epad- 10.6.1.14.10-2-13-8-1. (I understand this build is not rootable so I was going to either downgrade or try to load a custom ROM) Kernel version 3.1.10-gb1a9af5 [email protected] #1
When I get to the fastboot menu there are the three options to chose from and when I select the RCK I get the dead droid with error underneath every time. So I have been unable to load anything.

The dead adroid is the stock recovery. There are two option for you to install the custome recovery.
1. Downgrade your firmware version and use motochopper to get root before using goo
2. Use fastboot to install your custome recovery

The last few pages have an instruction and link to use fastboot.... Good luck..

Ok Scott's too rebooted the machine into Fastboot and the USB Driver is not recognized. I have downloaded the USB drivers from ASUS Sync program and unstalled Sync.
In the top corner it says:
Key driver not found...Booting OS
Android cardhu-user bootloader <1.00 e> released by "US_epad-10.6.1.14.10-20130801" A03
Starting Fastboot USB download protocol
The options at the boot menu are RCK ANDROID WIPE DATA
Not sure how to get the drivers to recognize....without that I'm dead in the water...any thoughts?? I thought for sure that the ones from ASUS would do the trick....
Should I have other menu options at Fastboot?

But I cannot as the USB does not recognize the device when it goes into fastboot. Works fine when in normal operation I can access the tablet through the USB, but in fastboot it does not recognize it. Can't seem to find a solution all USB drivers I have loaded do not work. Updating the drivers from the window on PC that opens does not work. UGH!!!!!!

I followed this to the "T"
This is the summary from the Scott post:
1. Download the "install recovery.zip" from the above link
2. Extract it some where on your computer, prefer in the document folder
3. Check and make sure that the "USB debugging" is ticked on your device under the developer option menu
4. Download the TWRP 2.6.1.0.blob file from here: http://techerrata.com/browse/twrp2/tf700t
5. Rename it to "recovery.blob" and put it in same folder with all the fastboot files so that you can use Scott's script
6. Double click on the Scott's script or bat file and follow the instructions on the screen until you see the phrase says "write is okay or completed"
7. When it is finished, you can now reboot your device, done..
When it reboots it will not load drivers and I cannot access the tablet / fastboot.
It shows this at fastboot and I cannot do anything. Happens with script and if I manually do it. I can't use fastboot no matter what I try the USB drivers do not recognize the tablet.

Follow this post - - > http://forum.xda-developers.com/showthread.php?p=30260444 <-- if you want to install the drivers.
Also make sure that you have a working fastboot environment and run the command prompt from the folder where fastboot.exe is located. The dead android you are seeing when accessing the recovery it's normal with Stock Recovery, nothing is wrong with your device.
BTW, i suppose that your device is already unlocked because otherwise Fastboot won't work.

Dead Droid with the word "Error" underneath it is normal?
Yes the device is unlocked. I cannot get into recovery and cannot get Fastboot to work because the stupid USB drivers don't recognize the tablet. Works fine when not in Fastboot mode, but when goes into fastboot no USB. It's maddening!!!!
Yes dead android it's ok.As for the driver just follow the link i posted and install the driver manually,that will solve the driver issue.

What Windows version are you running? Win 8 doesn't seem to recognize the fastboot drivers, or maybe it was that you have to change the option of Windows only using Microsoft signed drivers?? Can't quite remember. But lots of people were unsuccessful getting fastboot to work in Win8.

[Q] Problems installing TWRP on unlocked JB, wont go into fastboot

Hello everyone,
I am new to XDA but not new to the Android rooting, flashing industry. I've flashed and rooted several phones, aswell as my own phone with a custom ROM. So I figured, since mine tf700t hasnt any warranty anymore that I will install Cromi due to the lag of the original software.
In order to install Cromi you need an unlocked bootloader and TWRP installed. The unlocking of the bootloader was like stealing candy from a baby. Then i wen't on to install TWRP with this guide: http://forum.xda-developers.com/showthread.php?t=1833212
1) Install Android SDK
2) Download TWRP Recovery blob and check the MD5 sum (don't skip MD5 check,is there to make sure the file is not corrupted)
3) Rename the downloaded file to twrp.blob and put the file in the same directory as your fastboot.exe (unless you have /platform-tools in PATH then you can flash from anywhere)
4) Turn off your device and boot to fastboot (power on while holding volume down, then select the usb icon and hit volume up to confirm)
5) Plug the device into your computer
6) Run the following command via the command line:
fastboot -i 0x0B05 flash recovery twrp.blob
At step 4 I ran into some problems. No matter what I do, i can't seem to boot the device into fastboot where you will see the three icons, among them the USB icon. I watched several youtube videos and read everything i could find but still no solution. What am I doing wrong at this point? What I did noticed was that the volume up and down buttons in some videos where at a different place then mine are. I have a Tf700t, when it is in landscape the volume buttons are at the top right corner on the edge of the device, the power button is on the top left on the edge of the device. At some videos the volume button was on the left side and on the top right side. Does this maybe have anything to do with it?
Thanks for the help in advance. I feel kinda stupid to not get it into fastboot mode, this never was a problem with other devices...
What firmware are you on? That guide is not updated for newer firmwares as newer firmwares have already removed that usb icon in the bootloader screen. In order to enter fastboot mode, all you need to do is power + volume down (holding down both buttons) and you should already be inside fastboot mode, no other button needed. Otherwise, through adb, you can try "adb reboot bootloader", which should take you to fastboot mode as well.

Ah this explains a lot. Now when I connect it to my PC it is recognized, but when i run a 'fastboot devices' (eveything is set properly with paths etc) my tablet isn't recognized. Should I install a different driver? As for now my PC says it has APX drivers

It most likely means that you have the wrong fastboot driver. You should follow the instructions here (http://forum.xda-developers.com/showthread.php?t=2263822) to install the correct fastboot driver from the Universal Naked Driver pack. If you install the driver correctly, the tablet should appear as "ASUS fastboot device" in Windows' Device Manager. Then fastboot commands should work. As a quick reminder, the fastboot driver is a different driver from the adb driver. Windows will only see the fastboot device when you connect your tablet to your PC while the tablet is in fastboot mode, hence a separate driver is needed.
Moreover, when you flash the recovery later, you need to remove the dock and connect your tablet directly to your PC. In my case, even though fastboot recognized my tablet, the flash recovery command failed if the dock was connected.

I tried many drivers from the universal naked driver pack. But still, wen i type in 'fastboot devices' nothing happens, and with getvar i only get 'waiting for device'.....I really dont get it, what am I not seeing her....
But then again I cant seem to get "ASUS fastboot device" in windows device manager. Only Asus fastboot interface and some others with ADB etc. Am I looking at the wrong drivers?

I am using Windows 8.1, so the first step for me was to boot into troubleshooting mode of Windows to disable driver verification, but you won't have to do that if you use windows 7 or earlier. After that, open Device Manager, right click on ASUS bootloader interface (or a different name with the yellow question mark, but I remember when I first connected my tablet to my PC, the name was "ASUS bootloader interface"), choose Update Driver Software, then choose "Browse my computer for driver software", and click on "Let me pick from a list of device drivers on my computer". At the next screen choose "Have Disk", browse to the Universal Naked Driver folder and select the file "android_apxusb.inf". From the list you should be able to find "ASUS Fastboot Interface" and install it.

I really dont get it....It just wont work. Fastboot still wont recognize my tablet.
If i get my hands on another Windows PC I will make a second attempt.
If someone knows a different solution, please tell me. Fastboot on the pc is properly installed for whats it worth....
Try Goo manager Open Recovery Script
I am not sure if this will help you because I am also new to this but I unlocked and rooted my tf201 prime using the steps you did. I rooted my Tf700T a few days ago and my unlocked didnt work until yesterday using unlocker 8 from the Asus site but I still could not make changes to my recovery with Clockwork Mod or TWRP until I used Goo manager and ran the Open recovery script. It worked on my TF700T with build number JOP40D.US_epad-10.6.1.14.8-20130514 which has Android 4.2.1. Give it a try it is easy.
Peace. I hope this helps

Hello everyone,
I am new to XDA but not new to the Android rooting, flashing industry. I've flashed and rooted several phones, aswell as my own phone with a custom ROM. So I figured, since mine tf700t hasnt any warranty anymore that I will install Cromi due to the lag of the original software.
In order to install Cromi you need an unlocked bootloader and TWRP installed. The unlocking of the bootloader was like stealing candy from a baby. Then i wen't on to install TWRP with this guide: http://forum.xda-developers.com/showthread.php?t=1833212
1) Install Android SDK
2) Download TWRP Recovery blob and check the MD5 sum (don't skip MD5 check,is there to make sure the file is not corrupted)
3) Rename the downloaded file to twrp.blob and put the file in the same directory as your fastboot.exe (unless you have /platform-tools in PATH then you can flash from anywhere)
4) Turn off your device and boot to fastboot (power on while holding volume down, then select the usb icon and hit volume up to confirm)
5) Plug the device into your computer
6) Run the following command via the command line:
fastboot -i 0x0B05 flash recovery twrp.blob
At step 4 I ran into some problems. No matter what I do, i can't seem to boot the device into fastboot where you will see the three icons, among them the USB icon. I watched several youtube videos and read everything i could find but still no solution. What am I doing wrong at this point? What I did noticed was that the volume up and down buttons in some videos where at a different place then mine are. I have a Tf700t, when it is in landscape the volume buttons are at the top right corner on the edge of the device, the power button is on the top left on the edge of the device. At some videos the volume button was on the left side and on the top right side. Does this maybe have anything to do with it?
Thanks for the help in advance. I feel kinda stupid to not get it into fastboot mode, this never was a problem with other devices...

I had to flash it with openrecovery-twrp-2.6.3.2-tf700t.blob. using the platform-tools because I could not use the one with Open Recovery script by that time I wiped the entire device! It could have been my fat fingers but I just installed CM 11-20131221 (Kit Kat 4.4.2) on my tablet today without any issues. I have not done much with it yet but I will let you know later.

[SOLVED] Recovery and fastboot problems (soft bricked?)

I was given my friends tablet to try and fix for him. Basically the recovery (TWRP 2.5.0.0) cannot mount any partitions at all (and asks for a password for some reason - can be bypassed with the cancel button). The tablet will boot straight into the recovery mentioning that no OS is installed. I have attempted to boot into fastboot to flash an older version of the recovery (which I've read up on a few websites that say it will fix the mounting problem) however while pressing VOL DOWN and POWER it will boot up to the ASUS logo and no message appears about fastboot in the top-left. I'm out of ideas now and the only way I'll be able to fix this (from what I know) is either by flashing the ASUS firmware or an older version of TWRP via fastboot. Has anyone got any ideas on how I can fix this? Thanks.
EDIT: May be of reference https://github.com/TeamWin/Team-Win-Recovery-Project/issues/138
EDIT 2: I have finally solved the problem! I have quoted the important parts below in case anyone else has the same problem.
Basically I had some problems with the drivers the whole time on Windows 8. So what I did was disabled driver signature enforcement in Windows 8 (I think it re-enables after some time). I downloaded the drivers from this post and followed this other post , specifically this part:
jpasher said:
Making Windows recognize the TF300T
You will need to add the hardware IDs for the TF300T in the driver to make it recognize the ADB interface
Open the file android_winusb.inf in the naked drivers directory.
Look for the section titled [Google.NTx86] (for 32-bit systems) or [Google.NTamd64] (for 64-bit systems)
Add the following lines to make it recognize the TF300T hardware (it doesn't matter where, but I put it after the existing entries for the TF201 APX interface)
Code:
%AsusTransformerADBInterface% = USB_Install, USB\VID_0B05&PID_4C81&REV_0232&MI_01
%AsusTransformerADBInterface% = USB_Install, USB\VID_0B05&PID_4C81&MI_01
%AsusTransformerADBInterface% = USB_Install, USB\VID_0B05&PID_4C83&REV_0232
%AsusTransformerADBInterface% = USB_Install, USB\VID_0B05&PID_4C83
After the information is added, you should be able to install the drivers as usual for the device. If for some reason the device is still not recognized, you'll need to find its hardware IDs and add those to the file.

Then I booted up the tablet and connected to my computer. The drivers finally worked! I went into command prompt and typed "adb devices" and the device was there! Then I typed "adb reboot bootloader" and I got into the bootloader.
I had to look for the SKU too and since I couldn't find it cause I couldn't boot into Android it was in really small text in the bootloader at the top. Unfortunately after trying to flash the firmware in the bootloader it would not write over the system every time. So I followed this post instead: http://forum.xda-developers.com/showpost.php?p=49164067&postcount=167
After following the procedure it finally worked! Thanks cmendonc2 and everyone for your help, my friend is happy!

What bootloader is it on? It is on the top left corner of the screen wneh you enter the recovery menu in the bootloader.

It doesn't say in TWRP recovery. When I boot the device straight up in the top-left corner it saw device is unlocked. However holding VOL DOWN does nothing and the tablet boots straight into TWRP

You can still use fastboot in TWRP, but you will need to find the bootloader in order to figure out which recovery to flash over TWRP. There should be a fastboot command to find out.

Okay that's good to know. I am still unfortunately not able to get into fastboot. So I'll have to figure out what version the bootloader is before flash the firmware over.
Okay I got access to APX mode (useless from my understanding since my friends has no backups via nvflash), the bootloader while the recovery is loaded (although the driver isn't working for the bootloader), but I CANNOT GET INTO THE BOOTLOADER VIA VOLUME DOWN + POWER. Please help, somebody!
Here's a video explaining my problem.

Have you tried pressing the reset pin, then going into TWRP and going into ADB mode.
Then type ADB reboot bootloader and then try getting into fastboot by pressing volume down.

I tried it out but I get the the message "ADB Sideload Complete" and below it a message in red" Failed". I have it plugged into the computer and I didn't hear a connection sound.
I have also looked in Device Manager and there is the Transformer with no driver loaded with it. Further searching using the device information gave me this link: http://binarydb.com/driver/ASUS-Android-Bootloader-Interface-208738.html
EDIT: Found a driver on softpedia and installed it: http://drivers.softpedia.com/get/Ot...iver-4004-for-Vista-Windows-7-Windows-8.shtml Doesn't look like it's working though.

While the ADB is attempting to connect, reinstall the naked drivers. If you are on Windows 8, use test mode.

Just an update. I got it working!! I did the following on this post to the universal drivers and then tried installing them on Windows 8. After booting my tablet to TWRP and plugging it in to my computer ADB works! I can reboot into fastboot now. Now I either have the option of flashing a JB compatible recovery or flashing the Asus firmware...
Since I'm not able to boot into Android would anyone be able to tell me what is the SKU on the picture below? So I can flash the correct firmware.
EDIT: Found it in the bootloader in small text. -.- It was the "WW" version.

[Q] Stuck in boot loop, can't detect in ADB or fastboot

Hey guys, I really need some help here, I'm not good at any of this stuff - my OPO just randomly got stuck on a boot loop, I have never played with the USB debugging or any of that or tried to flash anything else, I was using just stock cyanogen.
I've been reading around and I've downloaded all the drivers but still can't detect the device when I do the Shift + Right Click --> Run CMD "fastboot devices" or "adb devices".
I never enabled options such as the USB debugging or anything else, can someone please help me out? I'm really clueless to all of this stuff.
You must first put your phone in fastboot mode.
To put your phone in fastboot mode, turn it off, and then hold power+volume down until you get a screen with only the cyanogenmod logo. If you get to this screen, you're in fastboot mode. If you have installed the proper drivers in your computer, you should be able to connect to the phone from your computer. Connect your usb cable to the phone and the computer, open a dos box and type "fastboot devices". If you get a series of letters and numbers then you're OK.

This, except that's the wrong button combo (power + volume down is for recovery). Use power + volume up to get to fastboot mode and then try the "fastboot devices" command.

There's no point in using adb commands in fastboot because only fastboot commands work. What drivers do you have installed?

I tried that, but again no response in CMD when I type fastboot devices.
Although I just tried and am able to boot into recovery mode, would I be able to do some sort of factory reset there? I've already tried to wipe user data but I'm still getting a bootloop there.

HELP!!!!! Stuck on bootloop and fastboot not working
i was flashing twrp on infinix s4 withfast boot. after flashing the device is stuck on bootloop. the recovery is not accessible (i press the key combo nothing happens) and fastboot combination is also not working. i tried connecting it with adb cmd and ran the command "adb reboot bootloader" but no device is detected.
ps: the link for drivers is broken
