No, you will not need to unroot, since you have root, you will be able to install the new version of android long before it is officially released onto the incredible thanks to all our wonderful developers.

 

If you are rooted, I would say do not accept OTA updates. It could cause problems. It could just take away root (though if you are S=OFF, you can just re-root easily). Besides, anything that is offered in the update, especially anything that is of any significance, will either already be in what we have available through rom devs, or it will be coming soon.

 

You will need to be on a custom ROM and S-OFF in order to not get that update.

Or so I hear...

 

new RUU already out [ROM]RUU_Incredible_C_Froyo_VERIZON_WWE_3.26.605.1_Radi o_2.15.00.07.28_2k4k_NV_1.70 - xda-developers

I recently unrooted, turned s-on and installed previous RUU waiting to see if I can receive OTA. If you are rooted or unrooted you can install the latest RUU (It is signed). As for the OTA, rooted with S-off is hit or miss for recieving OTA notification (Seems to not show up 90%+ of the time). Its just up to you, even with official RUU with S-On and unrooted I am unsure I will even recieve the OTA notification.

**Cant find the Verizon page with ALL details at the moment, on a time crunch

 

I rooted but i just made my phone S-on. Would it be safe to install the OTA update?

I get confused when people say i shouldn't or i should. Should i go back to s-off to install the OTA?

 

To ensure root, leave S-off. I would guess that if you can find anyone who installed via latest RUU and attempted root (Success/Failure), you will have a definitive answer. Good luck
