How To Enter APX

1. To enter APX mode you either have to boot, choose reboot (if available) and hold volume up pressed until it reboots and then the screen should remain black. Or if that doesn't work, completely shutdown your tablet and wait a second or two and then hold volume up pressed while pressing power on and keep it pressed until screen is blank.
or
2. fastboot -i 0x0B05 reboot (hold volume up)
or
3. adb reboot (hold volume up)
or
4. with unit powered on hold volume up and press reset with paperclip - (don't press hard)
reset is located about 25mm or 1in below the sdcard
or
5. su
reboot -hold volume up.
This is done using a terminal; Android terminal is free from the play store.You must be rooted for this to work.
or
Only 6. if there is no other resort!
6. remove cover from unit, disconnect battery, press and hold volume up, reconnect battery!
or
7. Another way:- Provided by daws
Power off the tablet and don't touch the power button again.
Connect USB cable to tablet but not to PC yet.
Press volume up and then connect USB cable to PC.
Wait a few seconds before releasing volume up button.
You should now be in APX mode.
Works every time for me.
Thanks for the help daws.

How To Enter bootloader – recovery menu

1. To enter recovery menu you either have to boot, choose reboot (if available) and hold volume down for pressed until it reboots and then the recovery menu appears. Or if that doesn't work, completely shutdown your tablet and wait a second or two and then hold volume down pressed while pressing power on and keep it pressed until recovery menu.
or
2. fastboot -i 0x0B05 reboot hold volume down
or
3. adb reboot hold volume down
or
4. with unit powered on hold volume down and press reset with paperclip - (don't press hard)
reset is located about 25mm or 1in below the sdcard
or
5. su
reboot -(hold volume down).
This is done using a terminal; Android terminal is free from the play store.You must be rooted for this to work.
or
Only 6. if there is no other resort!
6. remove cover from unit, disconnect battery, press and hold volume down, reconnect battery!
or
7. Another way:- Provided by daws
Power off the tablet and don't touch the power button again.
Connect USB cable to tablet but not to PC yet.
Press volume down and then connect USB cable to PC.

or - no need to hold volume with these
8. adb reboot bootloader
or
9. fastboot -i 0x0B05 reboot-bootloader
or
10. from terminal - you must be rooted for this to work
su
reboot bootloader

Note 1: If you are on ICS or have nvflash installed some of the commands presented in this post may not work; possibly 8, 9, and 10 - THANKS TO wha2do for this info!
Note 2: adb commands are available while in twrp 2.3+; if this fails update your version of adb and try again.
Note 3: as you go through different processes to recover you may gain or loose access to any of the suggestions in this post so try them again as you progress.

I've heard APX/NVFlash doesn't actually work in the most recent stock releases. Do you know what this actually works on and if you can actually do anything if you get into APX?

Nvflash can only be installed while on ICS and APX mode is useless unless you have installed Nvflash.
Once Nvflash is installed you can use ICS (android 4.0) or JB (android 4.1) rom.
I'm speaking of Nvflash and APX as they relate to the TF300T.

I flashed recovery on my tablet a few minutes ago.
I'm assuming here that you have nvflash installed.
wheelie -r --blob blob.bin
nvflash --resume --download 5 ProperRecoveryForYourBootloader.img - this file can also be blob.
nvflash --resume --go

Info:
I just realized something - 6 months - are you using flatline?
These instructions are for nvflash not flatline!
I have not yet investigated flatline.

boomingshot · Oct 8, 2013

Not to be a smartass, I'm a huge noob and appreciate all your help

But, when I try it I get the following error

I'm assuing that blob and bl are the same thing, I tried the following wheelie --bl blob.bin. is that the same thing

Thanks sooo much for your time:highfive:

never heard of flatline, could that be another potential recovery option?

so far only APX mode works on my tablet, all the rest is inaccessible

I downloaded the latest firmware from asus and copied blob (no extension only called blob) file into the wheelie folder like instructed.

I tried the command I say I would in my last post and it didnt work. I tried the following wheelie -bl blob and got this prompt.

Everyone was new at some point. Not a problem except I'm not helping when I give a wrong answer.
wheelie -r --blob blob.bin - not wheelie --r --blob blob.bin
is the proper command; I just proved it on my own tablet.
blob.bin is one of the files generated by nvflash
your command C:\wheelie>wheelie --bl blob is flashing a complete blob - I don't know what blob file you had in the directory.
Contents of a blob:
blob.PT - partition table
blob.APP - system.img
blob.LNX - boot.img
blob.SOS - recovery.img
blob.EBT - bootloader.bin

It is probably best to stick to the commands as presented.
We are trying to flash the blob.bin file you saved from your nvflash install.

Formatting is not working properly on XDA at the moment so I have no idea how this will look or read.

What version of wheelie are you using? Would you mind putting it on mediafire or something? In my version, which I thought to be the latest, wheelie -r is not an available option

I only have these ones

-1 or --sbkv1 Use wheelie for SBKv1 devices
-2 or --sbkv2 Use wheelie for SBKv2 devices

As you see I have less listed than you have but the version is the same.
Some have had issues with certain usb ports and others with windows in general.

I followed every steps and this tablet is not working, I'm seriously thinking about using it as my new Frisbee.

I'll right down all the stuff I did, so you can point where what I did wrong

1- Download Firmware From Asus Website

2- Download Wheelie/NVFLASH from
androidroot.mobi/pages/guides/tegra3-guide-nvflash
For TF300:
androidroot.mobi/download/tf300_nvflashpack.zip

3- Then the NVFlash program dosent even show the same option, I tried a different version of NVFLash and it want working either

You left out blobtools to extract partitions from your stock blob. It is unimportant at this moment with your other issues.

It will be a while or maybe tomorrow but I think I can borrow a windows laptop. I'll give it a try and report back.
I have a neighbor who has been very helpful in this respect. I do provide some help with his androids and laptop.

This is with windows 7 pro.
Both with the -r and without work on this pc.
There are three usb ports - one is usb2 and two are usb3 and all function the same.

I have used this laptop to restore my tf300t to stock ICS in the past. Tonight I just plugged in my usb drive and used the files left after my previous use.

Try all usb ports.

Hello!
A few days ago I tried to root my Asus TF300T because before that, I changed the lcd and the touchscreen from FPC-1 to G01 version. So I had to root and update touchscreen's firmware to 02-3011-4820.ekt. I already updated with last firmware from asus.com. First, I installed a TRWP recovery but was useless since the touchscreen doesn't worked. So I tried to rewrite CWM recovery. I reset it and I don't remember exactly if I begun to install or not CWM but when I tried to wipe data (Vol- + Power), the tablet has freezed. After a few minutes I did a hardware reset (pin hole). Since that, the tablet freeze with "Device Unlocked", Asus logo and nVidia. The device was already unlocked. I don't have any backup from it. No fastboot, no adb. Just APX mode. Is it possible to do something with it anymore? I tried BootTools2, extracted bloobs from last version of firmware, tryed to flash them with nvflash and wheelie but vainly. What is the next step? I'm a beginner!
Thank you in advance!
