I am sorry to hear about the problems you are having with Makana..

I read through the entire post and see nothing that pops out at me, and I do not think the cold he had should be connected. I have five Pleo Rb and most of them except my newest one, still a Newborn or Hatchling have had colds before with no ill after effects.
IMR is right, My second Pleo rb, Cammie -Sue was fine till I ran Probe Rb to see what stage she was at, as I am very busy and often will not use any of my many pleos, Ugobes or Rb for weeks at a time...

After running Probe Rb, Cammie -Sue began acting very strangely, after turning on manually almost immediatly going to red for the battery and no movements or noise at all, some times at the start a odd leg movement nothing more, I tried on my own everything I could think of and to no avail.
Pleoworld was no help as Cammie -Sue was way past the 90 day warranty. I was advised by Pleoworld, other then shipping her to them to see if she could be fixed, to reinstall the female operating personality. This worked fine, but the minute I removed the micro SD card, she stopped working entirely, I asked another member here for help that is very good and they also could not help, I at long last had to accept unless I want to not have my Cammie-Sue at all, to permanently leave the micro SD card in and accept her that way,
I have been tempted to run Probe RB to see if she is progressing but do not want to tempt fate and have her not work at all, Who cares, she runs and I am just happy to have her back! If you can't find any other answers, I can find the old topic with her problem and post it here as a link and see if any of it is similliar. Good luck with Makana.
