Thanks for this thread!
I went from a bone stock Rezound yesterday, to unlocked, rooted, S-OFF, running ICS firmware with Nils' Business ICS ROM and working (with WPA2) WiFi Tether today.
For those that follow, if you want to get to the same place that I am, here are the high level steps I had to go through.
- followed the instructions given here to unlock (using HTCDev tool).
- followed instructions here to root (which involves installing Amon Ra Recovery)
At this point, I tried to setup WiFi Tether and found that it will only work with the stock ROM with no encryption.
- used the wire trick to get S-OFF. Worked first time, no problem. This returned my phone boot loader to LOCKED.
- Installed the latest ICS RUU (3.14.605.5). This blew away Amon Ra Recovery
- Unlocked phone again.
- Installed Amon Ra Recovery again, but did not go through the steps for rooting again.
- Installed Nils' Business ICS Sense ROM (v4.1 for S-OFF).
- Installed WiFi Tether for Rezound (from a thread on XDA). Somewhere in there root status was preserved or else Nils' ROM was pre-rooted (probably the latter).
In retrospect, I probably could have skipped the first time around of unlocking and rooting, but oh, well. If I had known then that WiFi Tether wouldn't work with the stock ROM, I probably would have tried that route. Fortunately, those 2 steps are quick and easy (i.e. takes a minute or 2).
