Right now in order for u to get the. 894 update u need a new bionic so yes do the replacment if u want the .894 update. Second prior to doing the. 894 update forever root the phone cuz the .894 update does retaim root. Third theres no point to going back to the. 893 update cuz it is a bad update an not the most recent its a qoute/unqoute relief update not a full on like the .894 that actually patches the android os. And not just the kernel/radio and some enhancements for data connectivity that the .893 does
This sounds pretty ridiculous to me. So they send out a bad update and then they're going to send a second update that fixes all the issues but if you applied the first update they don't have enough sense to allow everyone to apply the 2nd update no matter what kernel and radio you have?
