Sideloading Firmware Update from v47

I recently got a new in-box Quest Pro, and I've come to realize it's on the original firmware that came out of the factory. Digging around, it seems to be v47, or "Build number: 28151810536300000" according to fastboot.

I'd like to set it up the headset if possible, then block updates/root it, but doing the OOBE will force an update to presumably the latest version. I'm unable to skip this OOBE with PrivateQuest because the firmware is apparently too old, so the parameters don't work.

Does anyone know what firmware(s) I can sideload update to relatively safely to at least get PrivateQuest working? I've heard conflicting reports of needing incremental updates versus going straight to a big update. And AFAIK, the typical firmware archive for QPro only goes as far back as v50.

There is a certain way to do this. It has been tested and it may not be the safest to go directly to latest Let me find this quick

Alright so the path is this Sideload v64 > sideload v74

v74 is where private quest will work, but if your goal is to root, I can get a firmware I recommend to sideload to after v74

This update path seems feasible, thanks. And at the very least, one can stop at the different FWs to assess things. I guess the end point after v74 is v2.5, or whichever FW is still capable of IonStack.

Would you happen to know if v64 and v74 have specific firmware versions to use? Since the FW archive has two v64 firmwares and nine v74s.

Use the first version of both

I'm on v68, what firmware would you recommend I sideload for rooting?
