How to root a stock Thunderbolt with newest update

[teknotronik]

My girlfriend accepted the update to 1.70.650.0 with the 1.39.00.0627 radio. (Official release with new radio) she want's to root her phone at this point and I was wondering if the Downgrade RUU would flash her rom/radio back to stock settings so all is fine or if it only restores the system but not the radio. I don't want her getting the security warnings from a failed downgrade. If anyone knows what to do please let me know. I don't want her to brick her device. Let me know!

I just rooted with the new update using the adb (2.5) method. You just have to flash the updated radio and current 1.70 rooted rom or a custom one. She shouldn't get any update warnings after that.
