AP2800 - Mobility Express conversion no space on device

Hi all,

I've picked up a few AP2802 access points. My plan is to convert one to ME software and have the rest as regular CAPWAP access points subordinate to it.

I can't get the conversion process to work though. I've done a MODE button 20s factory reset. Software running below:

AP Running Image : 8.5.135.0
Primary Boot Image : 8.5.135.0
Backup Boot Image : 0.0.0.0

If I do the ap-type mobility-express tftp://172.16.10.10/AIR-AP2800-K9-ME-8-8-130-0.tar I get:

AP6C8B.1234.1234#ap-type mobility-express tftp://172.16.10.10/AIR-AP2800-K9-ME-8-8-130-0.tar

It may take a few minutes to finish download.
If it is longer, please abort command, check network connection and try again

Archive done.

I've tried 8.10.196 also. Same thing, except 8.10 gives some messages about a seemingly successful Master being upgraded. The MD5 checksum of both .tars matches that on Cisco downloads. When I reload the AP, the software version shown is back to 8.5.135 despite it suggesting at least some of the upgrade worked.

I've Googled.. other people seem to have run into this but don't point to a solution. This video (https://www.youtube.com/watch?v=7E5qmmb_drQ) shows the chap running into the same issue and he shows the workaround of upgrading the CAPWAP software first (he's at 8.2.111 and upgrades to 8.5.x suggesting there's an issue with CAPWAP software <8.3.xx. So he upgrades.

If I follow his instructions, (using ap3g3-k9w8-tar.153-3.JPT.tar) my AP tells me that it's expecting an ME image. He says to use the same (ap-type mobility-express) command.

So I'm stuck....  how do I get this flippin thing into ME mode?

cheers!

Convert a CAPWAP AP to Mobility Express controller/AP. I added a trick and a solution to the most common insufficient space issue I see when doing the conversion. Commands Used: logging console disable capwap ap ip 10.0.0.101 255.255.255.0 10.0.0.1 ap-type mobility-express ...

Absolutely yes, I was deliberately verbose for that reason.
