[Asus Transformer TF700] Zeuszoos:
I think I would add; "Or if you have no recovery", meaning that you have not made even your first backup yet, to use for a recovery.".

I did not have one yet and mine got "boot loop bricked". And there is no coming back from that, by any method! You can't get any menu at all, even by manually holding the buttons and your PC won't even recognize your Tablet when you hook it up via USB (even with the Windows drivers properly installed), so you're just plain toast, period!

On a more positive note, TWRP would not work for me for as long as I have had it on there. "Reboot Recovery" in GooMgr doesn't work. It just boots thru to the Home Screen and it wouldn't come up even holding the buttons to manually go into it.

Why is that more positive? Because today, I downloaded the latest firmware for my TF700T, because I knew there was an update, but checking with the Tab kept telling me that none was available. And so I figured that I would just boot and hold the buttons and see about installing it through the factory menu. ASUS's web site just says to "Install it using SOP". Huh??? What is wrong with computer people and writing instructions for people?! Idiots!

Anyway, I booted into the factory menu and was about to pick the "Android" option (out of the three options) to get to an "Install" option, to get to the Zip file on my microSD Card and it suddenly started booting thru to my Home Screen. I was like; "Huh??? What just happened???"

Don't worry, I'm getting to the positive part. :)

So anyway, I shut it down again and powered it on again, holding the buttons and then pressing Vol-Up within 5 secs, like it says and guess what came up this time?

That's right, you guessed it (did you?)! The TWRP menu!!! :)

I had never even seen that menu come up and I did NOT run GooMgr AT ALL today! In fact, I had not run it again since I had first installed GooMgr and run thru the proper procedure for installing this recovery menu! Weird, huh? :)

Of course, now I was nervous and felt like I just got hosed, because I didn't know if TWRP could handle installing firmware updates or not and if it could, how do I do it within TWRP, ya know? So I did a backup first onto the mSD Card and then chose, "Install". After all, I was trying to install something, right? :)

So I chose that, told it to look at my mSD Card, chose the Zip file and told it to go for it. And it worked! My system firmware got updated to the latest firmware no problem! :)

So you'd think that would be the end of it. But of course that would be way too easy!

So what was hosed up now? TWRP stopped working (the factory menu reappeared) and my device became "unrooted"! So I used the DebugFS Rooting method again, which works flawlessly now (just make sure to run SuperUser afterward, before doing anything else) on the TF700T, with the latest update to DebugFS and it Rooted again just fine!

So now I had an ASUS TF700T Tablet, with the latest firmware, but no TWRP Recovery Menu yet. But I ran the "Install OpenScript Recovery", or whatever it's called from within GooMgr and it installed it fine. The "Reboot Recovery" option in GooMgr still does not boot it into the TWRP Recovery Menu and it still boots thru to my Home Screen. But if I hold down the buttons doing as I described above, then it goes into it fine. So I did that and performed another backup, so I'd have one that was done after the firmware update and the rerooting of the device.

So that's the positive thing! I now have an up to date device, with the TWRP Recovery Menu working and I finally have a backup, which really makes me relax a whole lot more when running my device, because I have had tablets hose up on me before and thank God I had a backup, because it takes me about three days to get mine back to exactly the way I had it!

But I still will NOT, NO MATTER WHAT, even though it may work just fine now, be trying that "Transformer Reboot into Recovery" app! I simply will not take the chance again, because I was completely hosed up last time and even if I had a backup then, there would have been no way to get to it and connecting it to my PC wouldn't work either, so given that it completely bricked me last time, I am simply not willing to take the chance, no matter how many people it works well for! It did not for me and it has not for some others and given that it's an unrecoverable bricking if something does go wrong, that's enough to keep me away from it!

Of course, to be fair to it, as I said, it has worked well for many and if it works well for you, I truly am glad for that and I hope it continues to serve you well. From what I understand, if it works the first time, you have nothing to worry about, which of course i good news to those it has worked the first time for. <lol!> :)
