Default [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/show....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/show....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?

Let me try to recall the exact steps that I did to get the driver installed. 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....

Default 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

Oh! GooManager works again? Which TWRP version did it flash when you ran the Open Recovery script?

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.
