Yes, you have to reroot.Anyone that has updated, did you lose root from .206 or .208?
I'm amazed at how many people in here are having trouble all of a sudden... I had no problems and all I did was repeat what I did to move from .84 to .208.. This is easy.
If you're coming from .181 all you have to do is:Yep. Not only that, but it seems that the steps all have a slightly different order to them, depending on which thread you read about what leaks. Ive tried every way I found instructions for. It always ends the same way... either I am on .181 or the phone goes as far as the M logo for about 20 seconds before powering down.
1. Fastboot to .181 to make sure you're completely stock
2. Root
3. Install ROM Manager
4. DO NOT CLICK INSTALL RECOVERY, AND DO NOT INSTALL BOOTSTRAP
5. Copy the update file and the .crc to /cache
6. Open /cache in a file browser of your choosing that will prompt you which application to use instead of opening the .zip file itself (I can't remember which I used, but yeah)
7. Tap on the .zip and open it with ROM Manager
8. Don't check anything in the popup and reboot recovery
9. It will flash and finish
10. Done! I recommend factory resetting again here. Reroot if you want.
