[AT&T Samsung Galaxy Note II] digitalnerd:
Good news! GPS is working again. It takes about 30 seconds to a minute to get a lock but it could be my location? It won't get a lock from inside, I have to be outside. Do I need to tweak it with TopNtp or something? I'm using the most recent files from the OP.

Mega-Dn3 V5 Final

dn5v2 update3_signed (I read this includes the most recent ATT GPS fix so no need to apply anything else. Am I correct?)

I went back to stock with this guide : http://xdaforums.com/showthread.php?t=2275844 (a big thank you to TexasPenguin for pointing it out and topgun303 for writing it up!)

Here is a screenshot before the OTA update :

I did run into one problem. After I downloaded the OTA update and the phone rebooted it got stuck at the "Samsung Note II" screen. I did some research and read flashing a bootloader with Odin would fix it.

I flashed the UCUCNE5 Bootloader pointed out by 2545 with Odin 3.07 : http://xdaforums.com/showpost.php?p=53841081&postcount=2 (Thanks Zen Arcade!)

Here is a screenshot from the terminal to verify the bootloader update took affect :

That brought it back to life but not sure if that was the proper way to do it?

Here is a screenshot of the details after the OTA update :

I continued with an AutoRoot-CF and TWRP recovery installation via Odin. Boot into TWRP and then flashed the "Mega-Dn3 V5 Final" and "dn5v2 update3_signed" zip files back to back making sure to ONLY DO A FACTORY RESET before hand. That is where I went wrong before, I didn't realize I was wiping way too much data . I need to read more about the powers of TWRP :eek:

Where do I go from here? Do I need to flash a kernel and modem? Here are the current details of the device :

LTE bandwidth speeds are slow but it could be my location? I'll have to try different APN configurations and locations unless there is something I should flash right away?

It appears I'm using the latest Modem/Radio according to the "About Device" device details and the one stop thread : I317UCAMH3 (Latest) Uploaded byGuitarboarder28

This came with the latest OTA update I assume? Since the this ROM does include a modem, there is no reason that would change. Is another Modem/Radio recommended? Or should I stick with what I currently have : I317UCAMH3

If you tell me to change the modem would I just grab whatever I need from the the one stop thread and flash it TWRP? Do I need to clean anything in recovery mode before I do so?

Do I need to change the kernel? I'm interested in the AGNI kernel but unsure if I'm supposed to use it right now because of stability issues with the ATT model. I don't have any WiFi issues but is AGNI supposed to improve performance? I assume my kernel is stock? 3.0.31-1398348

To take the AGNI plunge on the ATT Note II i317 would I flash PSN_AGNi_pureSTOCK-v4.2.4_N7105_4.4.2_AROMA-signed.zip with TWRP and then follow your latest recommended settings? Do I need to clean anything in recovery mode before I do so?

If i change these 2 things (modem and kernel). What in what order should I do it? I need to boot into the OS between installations?

Let me know what changes to make (if any) please.

Sorry for the long post! Hopefully this post can help some others. It's time for me to give something back. :good:
