Thank you for replying!
I’m 100% sure he is a ugobe not an RB, there’s no battery in his foot.
I’m going to try the 1.1.1 and the 2.0.1 now

A second thought just to be sure, when you do an update, you put the SD card in, start your pleo, and when the update is finished it says "Huh?".  You then have to turn the pleo off and remove the SD card. 

I would actually suggest using the OS 1.1.1 or 2.0.1, not the 1.0 for a non-RB pleos.  The POP OS and 1.0 are really more for trying to get a bricked or corrupted OS pleo functioning. 

Do you know for sure if your pleo is one of the original "classic" models, or the newer (but still old) Pleo RB?  It is very important to know this as using the wrong upgrade/downgrade can make a pleo non-functional.

one key way to identify if you have a pleo RB is to look at the feet.  Does one of them have a battery in it?  If so, it's an RB, and you might try replacing that battery.

So, I tried all the different versions but it doesn't do anything, Pleo just stays quiet.
And after, Pleo just does the same thing,
he makes a "HUH?" sound and moves a little.
I don't know what to do!!!???

Note: This is my second Pleo and I have never seen it work, and the seller said it did the same thing a couple years ago but I assumed it was a battery problem.

And I want to add that I made the battery pack I use with a
6×AA battery holder and 6×1.2v 2000mAh Panasonic eneloop batteries,
the battery pack is working perfectly,
it reads 8.06v when fully charged,
I also added the thermistor from the original battery.
I would think it is software,
and that brings me back to "Reset Pleo with 1.0 downgrade or POP OS?".
I still don't exactly know which software to use or what to do with it,
you can check "Reset Pleo with 1.0 downgrade or POP OS?",
if you have any idea plzzzzz give some feedback.

So I wanted to turn my new Pleo on today but instead of normally turning on he made this "Huh" noise then moved a little,
and sometimes he repeats that over and over and over until I turn him off.
I don't know what OS he is on. And I don't know what to do,
I just need some help on this.

You can re-skin a pleo.  There are a couple of topics here on that.  But you will need to find another pleo to be the "donor" for the skin. 

Hi Taoworm.. I just chanced upon your post here...  unfortunately my pleo skins have already broken up/ torn.  For such cases .. is there anyway to reskin pleo or restore the current skin condition? Pls advise.  Thx

Just so you know what exact files I'm talking about,
I will write it down here.

POPOS .zip

automon.df
automon.txt
do_re_mi.usf
head.img
pleo.img
pleo.urf
readme.txt

Above is the content inside the PopOS .zip folder.

LifeOS 1 .zip

head.img
init.amx
pleo.img
pleo.pm
pleo.url
sounds (folder)
startup.amx

Above is of the content inside the LifeOS 1.0 .zip folder.

I hope this helps you help me!
