@Kwb , im sure i read it somewhere but cant find the doc
I have checked the Release Notes Software Release 9.0.0.193 Oct 2018
it says the ss 5235 and the ss5212/5220 are out ( they are before my time so im not even sure what they are)
it does list the Dual 5215 5220 5212/5224 with firmware 2.5.0.5 so i take that as those will be best effort supported
From memory the original statement regarding 52xx series was that mitel were no longer going to put any TFTP related files into the builds and as you said when they
try and connect - no tftp file , no boot
in our CXII recently migrated and then patched to 9.0.0.193 we have these files in the /var/mitelphoneloads

Its confusing i agree because there is a L2Boot_5235_00.bin file there ?
i no longer trust much of what mitel are saying until i have witnessed it for myself
i think we may still have 1 x 5212 handset in our office so i'll see if i can find it and will give it a go on Monday.
If I never did anything I'd never done before , I'd never do anything.....
