I am pretty sure that T17,S17 ad S17 pro can use the same recovery files, you can take my words for it, as far as the E and + versions of both S17 and T17 I am not 100% certain of how they differ in terms of firmware, the reason why I initially thought that all the E and + versions could use the same the recovery files is because when you order a new control board from Bitmain labeled with (S17+,T17+,T17e,S17e) it comes with the MP Test firmware, and then whichever firmware you flash on it, it will accept it, Bitmain doesn't know which mining gear out of those 4 you have, and the recovery files all have the MP test firmware so I still think it will work, unless someone trusted like yourself, phill, thierry4wd or taserz tell me that they have tried E files on + files or vice versa and it didn't work.
