[Galaxy Note 3 Q&A, Help & Troubleshooting] lagoboss:
Thanks again JosHeron for offering to talk to Sammy in Panama for me.

I fixed my issue :D I used a XXUDNA9 4.4.2 KitKat rom that I flashed with ODIN 3.7. Once I flashed the rom, the phone rebooted and then it said that it was optimizing the apps. After that, I went through all of the steps and on the sign-in screen, it accepted my Sammy account and password on the first try.

Here is my theory on what caused the issue. When I did the recovery screen (vol up, home, power) wipe data and erase all, I think that it tripped the abnormal reset thing. Im not sure if it would do the processing failed if I had reset the phone from the settings menu. In any case, attempt to reinstall XXUDNA9 4.4.2 KitKat and then try to enter the Samsung account and Password.

Detailed Steps:

I am assuming that you have a SM-N900 International Note 3. If your phone does not boot with SM-N900 on the splash screen, find the appropriate stock rom for your phone. Otherwise, you can break your phone

This process should could take 4 hours +/- 1 depending on your internet speed.

Step 1: Get Materials (Adapted from http://nasirtech.blogspot.com/2014/02/n900xxudna9-android-442-kitkat-firmware.html)

- Download KitKat XXUDNA9 4.4.2 for SM-N900: http://terafile.co/3120933f433b

- Download Odin Verision 3.07 (3.09 does not play well with Note 3 and the old KitKat): https://copy.com/zowadQ32bn9T

Step 1: Factory Wipe and Clear Cache (Adapted from http://nasirtech.blogspot.com/2014/02/n900xxudna9-android-442-kitkat-firmware.html)

- Switch off the phone

- Remove the battery and then re-insert it after several seconds

- Next, press and hold simultaneously Volume Up, Home and Power.

- Release the buttons when the screen flickers and then wait for the Recovery Mode main screen to appear.

- If the Recovery Mode doesn’t boot, then you should keep trying until it does.

- Select factory wipe with the volume up key and then the power button, confirm

- Select Clear Cache

- Reboot the phone in normal mode by selecting the Reboot option.

Step 2: Make Sure the Phone to at least 80% capacity

Step 3: Reinstall KitKat XXUDNA9 (Adapted from http://nasirtech.blogspot.com/2014/02/n900xxudna9-android-442-kitkat-firmware.html)

- Switch off your phone and boot Galaxy Note 3 N900 into Download Mode by pressing and holding the Volume Down+Home+Power buttons (long press until the boot screen appear), now press Volume Up key to proceed to Download Mode.

- Extract the downloaded Odin3.07 zip file and run the Odin3 v3.07.exe file as an administrator (Right click on the .exe file and click on Run as administrator)

- Now connect your Galaxy Note 3 N900 to your computer via USB cable

- In Odin3 screen, you should see a COM Port number like “0:[COM7]” at ID:COM section and “Added!” text at the message box. This means -your device has been detected by Odin3.

- Make sure that, only the “Auto Reboot” and “F. Reset Time” options are checked. Failure to do so can brick (break/damage your device)

- Now, extract the downloaded firmware zip file, you’ll find a firmware file with extension .tar.md5

- In Odin screen, click on PDA button and select the firmware file with .tar.md5 extension (The firmware file look something like: N900XXDLJ5_N900ODDDLI7_INU.tar.md5)

- Now, click on the Start button to begin the installation process, wait few moments.

- Once completed, you would see “PASS!” message in ID:COM port having green background

- Your phone should automatically reboot after completion

- You can now disconnect your phone from computer

You should be able to enter your Samsung Account and Password without processing error_0000 now.

(Update: There is an issue with the Internet browser, flash the latest KitKat to fix)

Although it is fixed, I'm still scared about what else Samsung and Knox may do. I love the phone, but the thought of $700.00 down the drain was pretty horrific.

Lessons learned: Turn off that Samsung Activation thing before reset and don't update the phone until most users say that it is stable.

I hope this helps. I'm going to get some sleep. I've spent the night obsessing over it lol
