First of all, web injections stopped working after 9.5.0-22, thus ON 9.5.0-23.
Secondly, ram2sav cannot simply "be updated" to work on higher firmwares.
And lastly, the latest firmware is 9.7.0-25 (as of april 20th).

What I was talking about was that people who are still on 9.2.0 can spoof their firmware so they can download the patches even when staying on 9.2. However, since the later patches (ORAS 1.3/4 and XY 1.4/5) natively block the injection, the patches have to be temporary removed to be able to go online.
