I want to load WOA on my 950XL (RM-1116), ideally in dual boot mode with Win10m still accessible (no longer my daily driver, sniff). I have seen info relating to WPInternals 2.8 that I need to begin with a mobile OS build no newer than 15254.547 (Jan update) before unlocking the bootloader, but it currently has build 15254.566 (May update).
1) Do I actually need to revert back to the older build before proceeding (won't be able to unlock the phone), or is there a workaround to keep the phone (blind keystrokes, loading dual-boot, etc) as I have also heard may be needed for phones with the Jan update.
2) If I do need to revert to the Jan update build, how can I go about doing so? WDRT seems to show that it would revert all the way back to 10586.13169, and I assume that any automatic updates after that would proceed directly to the latest update.
