trying to boot in fastboot mode when children let me try that...

Edit: fastboot ok.

I placed the the files

KatKiss-6.0_TF701T_033.zip
open_gapps-arm-6.0-pico-20170120.zip
UPDATE-SuperSU-v2.79-20161211114519.zip

In
C:\Program Files (x86)\Minimal ADB and Fastboot

ok I don't know how to proceed now.

Seems I cannot change the recovery from CMW to TWRP,
My bootloader is 11.4.1.17 and the tutorial to install TWRP says in capital red:
MUST BE ON A BOOTLOADER 11.4.1.27, 11.4.1.29 or 11.4.1.30

So how can I do?
I there a way to upgrade the bootloader to be able to install TWRP?
Or should I Flash the custom rom from fastboot?

My TF701 in not booting anymore.... only bootloader and recovery CMW

the positive thing is :

C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot devices
15C3E10090400000011FA8580 fastboot

Please help

I have been able to flash CROMI X (unfortunately with strong battery drain) so CMW is able to flash but for some reasons not Katkiss 6.0.

I have been told that my problem is not ROM related... So it is recovery related?

What is the better option to get katkiss on my tablet? Flash the recovery to get TWRP even if my bootloader is 11.4.1.17 and the tutorial to install TWRP says in capital red:
MUST BE ON A BOOTLOADER 11.4.1.27, 11.4.1.29 or 11.4.1.30????

There is a technical reason about this warning?

Edit: I found this on an old post:

You can try this:
Download the stock recovery from here: http://droidbasement.com/db-blog/?p=3210
Copy the image to your fastboot folder.
Download the Asus firmware, unzip the file once and copy it to your internal SD.
Boot tablet into fastboot
Issue this command
Code:

fastboot boot recovery.img

Note: Do not flash the recovery, just boot it.
It should recognize the firmware file on your tablet and flash it.

Would this method work to get the latest stock rom from Asus?

Got your PM and will try to find some time at work today. Hang in there and don't do anything to make it worse

Ok, work was crazy busy so it took a bit longer.
If you flash a recovery that is incompatible with the bootloader nothing happens. Until you use the recovery... That could permanently brick the tablet. So heed the warnings, they are there for a reason.

Ok, let's try to get you on the latest bootloader. It's no suprise at all that nothing boots if you try to flash a Android 6 rom on an Android 4 bootloader....
Download either WW or US package from here: https://forum.xda-developers.com/showpost.php?p=61045480&postcount=2
That zip contains the latest bootloader and a compatible TWRP recovery. Flash the zip in your current recovery just like any rom, then reboot.
When you flash a bootloader or recovery you actually write those files to the staging partition. On the next boot the bootloader will unpack it and write everything to it's proper place.
So it's essential that you flash, then reboot. Does not matter that the boot does not go anywhere. The first part, flashing the contents of /staging to it's partition(s), will happen anyway.
You should see a brief blue bar filling up when that happens. It does not take long.
Boot back into fastboot and check your bootloader version.
Enter recovery through RCK and that should be TWRP now.
Then format /data. Do not wipe it, format it. Do not interrupt it. Wait for it to finish even if it takes an hour (a full battery is a must before you start this). The format command is under the Wipe menu.
Unfortunately the formatting in this kanged TWRP is pretty buggy, but I still like it better than CWM.... If you get lots of error messages after the format (cannot mount this, cannot mount that) go into Wipe > Advanced > select Data > Change or repair file system > Change file system > choose ext3 and execute
Note: The button you have to swipe is pretty "sticky". Swipe it slowly and fully
Reboot to recovery
Go back into Wipe > Advanced etc and change the file system back to ext4
Reboot to recovery
Now everything should be ok, try to mount/unmount data.
Finally you are ready to flash Katkiss

If the bootloader flash does not work, we can try to flash Asus firmware in fastboot, but try the above first.

Thanks a lot to take time to help me.
Will try that tonight and I'll let you know the result.

Thanks a lot!
It was just like you said.
I had to format to ext3 and ext4 because I had errors.

Battery seems to be very good. Just the screen display is very white, needs color saturation and contrast I guess...
Thanks again you save my tablet.
