Galaxy S4 Active With 4.4.2 NH4 ( Options & Opinions For Updating Welcome )

Just got this att G4 ACTIVE On Str@ightT@lk
SGH-I537
BaseBand version = I537UCUCNH4
Build number = KOT49H.I537UCUCNH4
OTA updated To NH4. Never been rooted.
It fails to update any further to Lollipop.
After downloading the update it restarts and says Installing...... but before its done it reboots.
MESSAGE Update Failed "Software Update Interrupted"
I tried manual method, renaming the file to update.zip on SD and get this ERROR
"error tmp/sideload/package.zip status 7" During install
it wipes the phone and no update

Most guides pertain to NE3 , NH3
How does Having NH4 change things?

Unlocked Galaxy S6 Active?

I would like to purchase the GS6A from Amazon. It's without a plan but it is locked. Will I be able to unlock it in my country if I don't have any account at ATT's, etc?
How does that work?

Best strategy for updating an unlocked S5 Active

Last phone(s) I updated via Odin were S4 Active, received a couple repaired S5 Active(s), both unlocked GSM (for AT&T and similar)

Is there a recent thread (did search first but not sure of results) with the multi-gigabyte link for download archive if so, kindly post it and I will download the 5x image and update these phones.

Apart from powering these on, have just verified they run 4.4 and are unlocked but will not insert SIM card until I have updated these.

Kindly note.. Yes, I do understand I could simply insert SIM and allow AT&T to do their thing OTA.

Thanks !
