I've got the stock TW mk2 build on my s4 and I'm having trouble getting it to sucessfully install the nc5 update. I'm trying to update via the OTA. The problem is basically an error during the installation of the update, my phone boots back up then I get the message that the phone was not updated sucessfully. I'm not sure whether there's an error number associated with this, but my phone does show the "Samsung Custom" splash screen with the unlocked symbol when I restart it. I've been out of touch with roms, rooting and such, so I'm looking for some guidance on how to get back into this. I want to just install the latest update and I don't mind losing root. can anyone please assist ?
