I'm sending my phone back to HTC becuase since day one it's been presenting issues (loose screen, the volume button is saggy and ultimatly what made me send it back, the camera seems to be having issues, I get the "you are blocking the secondary camera" message, when I'm not, and the camera can't focus correctly making the pictures extreamly blurry.
anyways, I'm getting the phone ready to sent it back, I flashed 1.54.401.5 firmware and went back to my old nandroid backup which was in 4.4.2, I flashed the stock recovery 1.12.1540.17 and the CID to the original one BS_US002.
I did a factory reset in the stock recovery and set up the phone, however I'm not getting the OTA for 4.4.3 and I have no idea what I'm missing...
any help would be highly appreciated.
ps: I used this as reference.
