I did the same thing and got the same "no update.."
I am not sure how to use this OTA file. Would someone kindly chime in. I did a lot of searching this morning still not much luck.
I have unlocked bootloader, S-OFF, TWRP, on 4.3 using RUU, rooted.
Question:
1) I can I use this OTA image with TWRP or must I use stock recovery. If I must have stock recovery, how do I get back Stock recovery, without going through RUU again?
2) can I use this with SuperCID?
Sorry if some of these questions maybe obvious to you but I am new coming from Galaxy Note 2 last week.
