since you are rooted you should be able to reflash the recovery partition. i would suggest you grab the cwm one click package and flash cwm to your ouya. then you should be able to go into recovery.
otherwise try with safe recovery.

have you tried rebooting into recovery form a shell, like this
adb shell
su
reboot recovery
if you don't have ADB set to run as root I'm not sure adb reboot recovery will work for you.
you also may need to hit the home button the the USB keyboard to get the menu to show up.

Thank you Ill try when I get home and let you know how it goes.

How to enter recovery mode?

I've followed youtube videos and other sites to enter recovery mode but all i get is an option to factory reset or to exit. I've held down the volume down and power key together until the LG logo appears and then let go of the power key after a second.
What am I doing wrong?
Thanks

What android version are you running? And how did you install the recovery img? And which one? If you installed the recovery properly and want to enter via hardware buttons it's the correct procedure.
--> If you're in the LG Stock recovery (where it asks you if you want to wipe your phone) just click yes twice and you'll boot into TWRP or clockworkmod (Whatever you've installed). I know that's a dumb way but it works
Note: If you didn't install the recovery correctly you will then wipe your phone!!!
To find out if you've done everything correctly with your recovery (and if you're rooted) just use the app Quick Boot from the play store, grant permissions and reboot into recovery. If you've done everything correctly you will be in recovery mode then And you can be sure that everything is setup correctly and use the hardware button method to access recovery (Just like I told you).

I'm on MM without a custom recovery., I'm hoping to just get into stock recovery and wipe cache partition. Is there even a stock recovery? Maybe factory reset yes/no is all there is?
Thanks

Nope and yes - There's only the option to factory reset if you don't have a custom recovery installed. Sorry to bear the bad news I thought you had a custom Recovery installed and don't know how to enter it. There's no stock-like recovery to access on the G4. Sorry :crying:

Do this, install lgup on pc, plug in usb, start lgup, let it detect on com port, click com port, ui will open, then click pbone info, it establishes avalid usb connection to phone, when it has, start adb prompt and type ' adb flash recovery (recovery image name) when done type adb reboot recovery and you're in recovery.
Just remember twrp recovery image must be in same folder as adb istalled to)

on Stock MM?

does this work on stock MM 20A or 20B without unlocking bootloader. i'd do it even if its just temporary to wipe cache and return to stock recovery after the wipe. factory reset just is too much to start from scratch with installs and setups. i am Never Buying a LG phone ever. it was my mistake

I have an unlocked bootloader, twrp (2.8.7), root and on MM V20a, Stock.
I can boot into revocery via adb reboot bootloader / fastboot recovery boot twrp, all works fine (excecpt that I cant access the external exfat sd card with cm12/cm13 based roms).
But I cant boot with Power on /Vol down keys intoTWRP recovery.
Altough I can boot in LG factory reset menu but if I perform that it wipe indeed to facotory reset no way to reboot in recovery.
I try it a couple of time without success. Also I try differnt key combinations (Power on / Vol Up + Vol down etc.), around 15 times.
Also I cant use tools like "Quick Boot" I try 4 or 5 diverents the result is always the same - android on the back with open hatch.
When I try to boot on CM12/CM13 via Power Menu directly to recovery the same effect occurs.
Whats gos wrong? Where is my mistake?

If you flashed TWRP, the "LG Factory Reset" menu will still show up. Just confirm 2 times with yes there, and TWRP will get started . Bit confusing, I know.

As I wrote - when I do this a factory reset is performed - no recovery.
Thats is my problem and unfortunately not the solution.
Update:
This is the solution:

So there is no option to clean system cache without installing custom recovery?...

Does this happen to anyone else? Can't access TWRP unless I flash it

So the only way I can get to TWRP is by flashing it.
Everytime I do the button combination to go to recovery while the phone is off, it takes me to the LG thing and says "would you like to reset to factory settings?" and only says "yes" or "no."
No TWRP at all.
If I choose yes, then all my data is gone. If I choose no, then nothing happens.
The only way I can get to TWRP is to go on fastboot, and do "fastboot boot twrp.img"
If I do "fastboot flash recovery twrp.img" then it does nothing.
Any help is appreciated.

You can either try this, or you maybe need another method. I had the same problem when I installed TWRP on 6.0. It didn't seem to be properly installed. What I did was
- Use LGUP to go back to 5.1 Stock ROM
- Root it following THESE instructions
- Install TWRP (Works flawlessly on 5.1 and you can use Quick Boot from the play store to check if it works)
- And THEN Upgrade to 6.0 with autoprime's Guide --> THIS one
After I did this I had rooted 6.0 with TWRP working. Maybe this will solve your problem. Cheers

the recovery is there, just say yes and yes and it will load

It just wipes my phone.

If you're at TWRP, reboot with it into TWRP again. Just follow the instructions and deny SU-things, you get presented. You can also flash SuperSU through it, boot up, install Flashify and install TWRP with it - also works great (did it this way). Just download TWRP from the official source & don't download it through Flashify.

You have only copy the twrp-xxx.img to your internal storage or sd card.
Boot via adb into TWRP, go to install, choose the twrp-xxx.img flash it as revovery and thats it.
Now you can rebooter apps to boot direcly into recovery or use the power down/power key combination during while you power the phone.

Download and unpack/unzip the file in my link below, if all goes good you get a file named: recovery.img after that:
https://mega.nz/#!QIZQ0LJT!eqJg2ysy_THf1i8skuks78WwKZwszzcog_ao4Ott7C4
Try to boot into fastboot (power button+volume down) and open up a command prompt, and navigate to the map where you downloaded my recovery, and typ in: fastboot flash recovery recovery.img

Are you able to go into fastboot mode ?
If so then flash this TWRP http://forum.xda-developers.com/devdb/project/dl/?id=21835&task=get
By typing fastboot flash recovery <name of the twrp you downloaded above>
