I really appreciate the work you do on this Bud, it must be frustrating to have some random guy on ebay profit on it.
I have searched the thread and read the last 10 pages or so. The only reference I can find to the 2.1L hardware revision is pds and darix362 upgrading their E5xt cameras, nothing about the E4. Does a E4 wifi 2.1L hardware revision even exist / is the E5xt similar enough to the E4 where it does not make a difference?
The procedure for upgrading the camera seems simple enough, I just wanted to check if anything has changed recently in terms of software or hardware revisions. I guess if I receive a camera with a new hardware/software revision that will not work I can always return it, but it would be great if that could be avoided.
