Samsung Galaxy Note 3 — Galaxy Note 3 N9005 Not Functioning Well After Firmware 4.4.2 Flash

Details:
Phone Model: Samsung Galaxy Note 3 N9005
Current Firmware: Kitkat 4.4.2 (very likely bugged)

Hi,
I'll list the issue in 2 parts for easier interpretation.

**PART I**
My phone was on Lollipop 5.0 firmware, I followed this guide on Youtube to downgrade: ]*Tutorial Downgrade Galaxy Note 3 from Lollipop 5.0 to Kitkat 4.4.2 Installing a fresh OS Fixing Bugs* (watch?v=CtTVHTSlHtg)
The firmware I used specifically was: N9005XXUENA6_N9005OLBENA2_XME

What happened after flashing was this error: Unfortunately Setup Wizard has stopped working
I rebooted the phone in safe mode (Vol Up + Power Button + Home Button) and cleared cache and data

Then I completed the setup wizard, Wi-fi works fine & phone was able to be rooted
But the phone had these issues (even before root):
[*]Occasional freeze when unlock screen with swipe
[*]Restarts occasionally
[*]Baseband Unknown
[*]IMEI Null
[*]Mobile network not available


So I rebooted the phone in safe mode (Vol Up + Power Button + Home Button) and cleared cache and data

Problems still persist.

So I went to PART II

**PART II**
I followed this guide on Youtube: Unroot your Android phone + install stock Firmware (watch?v=3hVTzeLlvlg)
The firmware I used specifically was: N9005XXUGNI4_N9005OLBGNL1_XME
Now it is in black screen, and this comes up after awhile: *Unfortunately Setup Wizard has stopped working*

Please advise on what I should do to rectify issue.

Thanks in advance!

Seriously, no one's capable to solve this?

IT'S FIXED!
I reflashed it with firmware from the country I live in and it works perfectly, running KitKat!
