DroidX 2.2.1 Unroot / Upgrade / Re-root
I'm sure this has probably been covered before, so if it has been please send me in the right direction.
DroidX running 2.2.1 (Froyo), and rooted. (every day I tap "Install later" when the "time to upgrade" pop-up makes its annoying appearance...for over a year)
I'm also running a custom ROM (DarkSlide).
I figure it's time to get current, but I have a couple of questions in this regard:
After I get current (Gingerbread), will I still be able to root to get all nifty and everything again? The main things I don't want to lose are Wireless Tethering and Titanium Backup).
So, making a slightly educated guess, please tell me if I'm close:
Return to stock
Upgrade to GB
I'm sure Z4 Root will unroot, but I'm sure I need to return to stock to upgrade to GB. The biggest mystery is how to get back to stock.
Once I do get back to stock, (and go through the laborious task of initializing the device again), is Z4 Root the key to re-rooting?
Will Wireless Tether run on GB, or will it require a patch or fix?
I do have Titanium backup, which I read is essential to success.
One last question: Blur or Non-Blur? I'm looking more for performance than features, so I assume that non-Blur will give me better performance, but what would I be losing if I chose that over a Blur ROM?
Sorry to sound like so much of a noob, but I'm the kind of user who gets his phone the way he wants it and doesn't touch it for a (very long) while.
If anyone could lead me in the right direction I'd really appreciate it.
Many thanks, in advance, for any assistance offered.
