Hi,

I just reinstall Chrome Os after having tried Ubuntu. It was a bit difficult to do, but it works well. 

Only one problem remains: impossible to update the system or to switch to other channel. 

The version of the OS is currently stuck on 36. I found some stuff about the policy in Chrome Os, but when i go on chrome://policy all of them are disabled...

Is there anyway to solve this issue?

Thankls !

hardware_class="X86 PEPPY TEST 4211"

that looks wrong, like an invalid hwid

did you get updates before installing Ubuntu?
Also did you overwrite your firmware somehow?

Hi

Thanks for your answer.

I installed all updated for CrOs before installing Ubuntu (as far as i remember, it was version 37)

To install Ubuntu, i used this tutorial http://www.circuidipity.com/c720-sidbook.html

Then,  to restore the original firmware i used this: https://johnlewis.ie/extracting-the-shell-ball-rom-using-a-chromeos-image/

I also put the gbb_flags to 0

In fact, my Acer C720 is now recognized as "X86 TEST peppy 4211" as the model...

What I mean is, did you ever receive an auto-update? I'm trying to
determine whether you've always had this hardware ID or not. If you
have, chances are you've not gotten an auto-update in the past either
and you probably need to return the machine since it has an incorrect
ID.

Hi,

FInally i managed to rewrite original hwid, using this https://code.google.com/p/chromium/issues/detail?id=222462 (post 8) and the orignal C720 hwid.

Now, everythings work great !

Thanks for your help

Ok, if you're able to write that then you must have removed the
write-protect on the spi flash and overwritten it. Basically, I would
say our advice is "don't do that" because of problems like this and
the possibility of bricking the machine, but I'm glad you were able to
fix it. I would recommend re-enabling the write protect.
