Hi, I'm not yet ready start to flash my TF300TL, but today I try to access bootloader menu (Restart and press hold volume down + ON button).
and i accidentally choose (volume down) and chose the "USB icon" and ENTER (volume up), and now my device keep showing "Fastboot USB Download Protocol".

How to cancel this? If not mistaken, need run one command from PC after plug in the USB cable.
Is that anyway to cancel it without using command from pc?

I really newbie and do not know how to cancel, please guide me step by step, thanks in advance.

Well, i'm planning to root for my new unit TF300TL (4G/LTE), until now I still do not understand and how to start it.
Can anyone point me a direction step by step how to root / unlock for my device so that I can flash it with CleanRom?

Really appreciate if got a simple step by step before I can flash it.
and I'm totally do not know what is fastboot, bootloader, CWM and TWRP, anyone can guide me? :cowboy:

If without anything now, can i just download the ROM and flash it directly?
or I need to unlock something or install something before can flash it?

~help~help~

You need to install ADB platform tools (search the forum for it) and proper drivers (I used Universal Naked Driver), then follow the directions in this thread. The driver will enable Windows to "see" your device as fastboot, and the platform tools will allow you to issue ADB commands from within its folder. You need to also put your tab in fastboot mode (if you have custom recoveries such as CWM ot TWRP) by going to recovery menu and select the USB icon.

Note: once in cmd admin mode, you must first navigate to the platform-tools folder, wherever it is located. Ex: cd C:\platform-tools\ assuming that your PT folder is in drive C on your PC.
