Two question about rooting

[Arjoma]

Hi everyone!
I just wanted to ask a few things referring to my TF101.
Fifa 12 doesn't work on it (strange graphical errors, even at the downloading dialog). I think Chainfire could solve that.
So I'd need to root my tablet. I've rooted my phone and installed hundreds of ROMs on it, I am just not so sure with my Transformer. I think I know how to do it, just some questions about it:
If I root, will the ICS update still arrive as supposed?
And if something should go wrong, I think I can still flash a clean official Asus firmware file to get it working again, correct?
Tanks!

Root only with stock recovery will still allow OTA update.
If you install CWM recovery than OTA update will not stick.
What's your serial #? As that will determine if you can use NVFlash or not in case
something does go wrong.

No need to install CWM right now.
My serial number: B70KAS313867

With a B70 it's one of those that could be a SBK v1 or SBK v2.
You can run SBK detect to find out.

So the only way to find that out is to use Ubuntu for SBK detect? Hm, I may try it when I have time. So as I understand, if I have SBK1, the device is nearly unbrickable, if I have SBK2, it's not (because when it doesn't boot and is stuck at a certain point I can't access it anymore and cannot repair it by flashing a working system on it again).
But, if I would just root it to install Chainfire (no CWM, no custom ROMs etc at the moment) the chance to brick the tablet isn't that huge anyway, right? (I know you can never guarantee 100%)

It is not very complicated to do.

I used Ubuntu 11.10 desktop for this. Drivers are included.
Just download, put it on a cd. Boot your pc with this (don't install Ubuntu but use it as a live cd).
Browse to this thread in Ubuntu and download sbcheck, untar and run it.
And of course put your tablet in APX mode.

Hm, I found a Ubuntu live CD (the 10.04 LTS version) and the CD worked.
Wifi doesn't work with it but I copied the tar file to a USB stick and opened it on the PC running Ubuntu.
But what now? I can decompress it, then there is a file without an extension and it cannot be opened.
Pressing Power and volume up on the Transformer doesn't help that much, because when you connect it to the PC it will boot regularly.

For APX mode:
Turn tablet off.
Connect cable to computer and turn device on while holding down Volume Up. Screen will stay off, but USB will come on.

The file is without extension and named sbkDetect.
Try:
./sbkDetect or
sudo ./sbkcheck

And this is exactly why I hate Ubuntu. I'm theory almost everything is perfect, in practice nothing works :banghead:
Maybe it's because the version is still 10.04? Or am I just too stupid?
The unknown file without am extension cannot be opened! (which program do you want to open it with? )
And I also don't know where to enter the commands you recommended (typing them into the terminal program, with or without the file path, won't do anything useful).
Would you help me again?

If you brick but use stock recovery, can you not just use the ASUS update system thing to flash the stock ROM back?

I don't know as I'm not really experienced in messing around with my TF101.
But could someone who has that experience just give an opinion,
if I just root the Transformer and use Chainfire, isn't the chance to brick the tablet rather small?
I actually wanted to be sure if I have a fallback and can flash a working system again if something went wrong.
