Sorry for the late reply,
Been spending too much time on the P3 thread lately trying to keep up around working.
I posted originally thinking that using the SDK interface would allow you to tell if you were in the bootloader or not (remember reading something about that in the past...), and you should be able to unroot from there.
BUT...
after reading the crazy responses of sixty some pages of posts in the last couple of days about the 'days to come', I think we should all take a look at what we do.
I agree that taking the phone back, explaining that it was dropped and the screen no longer works should be a call that Verizon makes about warranty replacement or not. I know that these new phones are a lot more sensitive than my old Samsung flip phone, but a mild drop 'With a case on!!' should not cause a hardware malfunction.
Now, about the root thing...you violated TOS when you did that, *but* it had nothing to do with the trouble you are having. If you had constant reboots and FC's because you cooked the processor it would be a different thing altogether.
I hate to say it, but it's becoming a situation that when we choose to root, we take responsibility for the hardware, even if the malfunction is not due to our actions. The more of us that follow that lead, the less likely the 'Doom N Gloom' we've all been reading about will come to be. Sucks, but it's the honest truth.
Yes, you should be able to unroot without seeing your screen if you know what you are doing, and if you feel that the damage to the phone is completely irrelevant, I encourage you to do so...bear in mind that repercussions may be coming that will not allow this in the future. And honestly...I just got a D1 on ebay for $100...as a back up. Why even put your name in the system if you have a long time on your contract (I've got almost a year before renewal - and a tad over for completion!!)
If you didn't root using SKD/sbf, then you should probably just eat the insurance charge and go on. If you are comfortable with operating your phone from the computer interface, then you most likely did nothing you are unaware of, other than dropping your phone and can recover it to a point that a legitimate claim could be made. I still doubt that Big Red will honor a warranty claim for a dropped phone, but it's worth a try.
Too long winded again...
