I have a CDMA HTC DESIRE that had 2.1 stock, I rooted it using unrevoked and recently there was an OTA update w/ 2.2 and I have saved it to sd card hoping I will be able to use it. Unfortuntaely, I have really messed up my phone as I downloaded the wrong official RUU,(which removed unrevoked root), unable to access clockwork recv as I keep getting red triangle w/ an ! and now I am also getting a pic of a phone w/ a red question mark when I try to do a flash. I am able to now root again with Z4root and also have the official OTA update stored on my PC and when I attempt to install on phone I keep getting the whole aborted signature failed status 7 and etc.... I have tried the various .zip methods recomended in the posts but with no luck and I am very frustrated. However, the good thing is that I am able to make and receive calls at least. I am in way over my head and realize my ignorance has brought this upon me. Any help is very much appreciated as I have spent all weekend trying to get back to my original stock 2.1.
