Hello. I had a hard time finding an update to Dingo that would work for me after I had updated to ermine. Apparently many of the "golden" updates that are around on the web have some sort of check in them that kicked me out of the update process for whatever reason. Eventually I figured out how to remove it, but afterwards I found this thread:

The second post has a link to the modified golden update to Dingo that should work for you. Remember, if it is working it will get stuck on the updating screen forever until you force reset. This is because it has to be run twice in order for the golden part to finish due to some crazy CRC checking that I only pretend to understand. The "official" procedure is to use the update.zip updating process as per usual and let it sit on the updating tablet screen for about 10 minutes and then hit the reset button. After that, boot it as if you're doing yet another update.zip update while leaving the USB drive in the PE (or sdcard if that is what you're using) and it should go through another update that shouldn't get stuck forever this time. Eventually it will reboot and should at this point be 100% reflashed with Dingo 1.13 I think but it might be 1.11 or something which shouldn't really matter.
If the issue your PE is having is software based, this should fix the issue. If it is hardware based, it actually still has a chance of solving the issue but probably won't. I have read about a small number of people having more hardware issues in ermine for whatever reason probably due to the hardware itself being just barely good enough to run the older version of android or whatever. Just some stuff that probably SHOULDN'T happen but might. Good luck!
I am also pretty sure that the sticky thread for resources for the eDGe in this forum has more than one link for the Dingo golden update that aren't related to the old websites. Unfortunately for me, those versions didn't work as they were supposed to for my PE and I need to remove the version check to get it to flash. Feel free to try either version and I hope your issue is just some random software problem so you can get back to using your machine! I liked my woot PE so much I went ahead and bought another one even though that is mostly useless but I'm a weirdo what can I say.
