I'm looking for (2) , The quest 2 OEM is locked. I know people have been able to bypass it in previous versions, but I'm already way past those versions and there's no way to downgrade.
Discussion
(1) may reduce the odds of bricking the device, but let's go with (2).
All OTAs can be found here https://github.com/QuestEscape/updates and https://cocaine.trade (lol).
If OEM unlock option is disabled on Developer Settings (hidden android settings can become visible with "adb shell settings put global development_settings_enabled 1" and https://m.apkpure.com/hidden-settings-for-android/com.jami.tool.hiddensetting) then have you already tried
(1) DownQuest https://github.com/basti564/DownQuest
(2) Flash unlock_token partition ("legitimate unlock") https://github.com/QuestEscape/research
(3) Telling Zuck you are making the first VR BTC HWW (lol) https://www.tradingview.com/news/tradingview:fc74aa984094b:0-meta-quest-os-open-to-third-parties/
(4) Shizuku + Setedit to manually set all oem setprops to 1 and then unlock both on Developer Settings and with fastboot?
