I searched around a little bit and I have a good idea on what to do, but I wanted to double check with you guys.
I just received my Droid X three days ago. After playing with it for a few days I noticed that there a screen problem. I was able to replicate the problem in Stock 2.340, GummyJar2.5, and Rubix 1.9.5.
After replicating the problem on all these roms I concluded that the phone's screen is defective. I flashed back to stock 2.3.340, wiped data/cache, did factory reset in the stock 2.3.340, and called Verizon and worked with their tech support but we couldn't fix the problem. Then they said that they would send me a replacement phone because I am still within the return window.
I want to make sure that when I return my defective phone to them it is stock and they won't give me any hassle.
My plan is to run Maderstock's OTA 2.3.340 update.zip. After Maderstock's zip removes root and clockworkmod and returns me back to stock, will that be enough so that VZW doesn't know that I rooted and accepts my phone exchange?
