Seems like an extra step, is using a different sysUpdater really all that important?
Is Julian's build more safe somehow?
I'm asking this because I've done successful downgrades with SafeSysUpdater.
Julian's sysupdater isn't safer , it just installs and deletes the cias one by one and it installs native_firm at the end , so if you end up getting a softbrick halfway through you'll be able to use recovery mode
