@lakota Thanx again mate 4 your assistance, I'm Trying 2 Uninstall the UbPorts Recovery or OverwRite it w/ TWRP or CWM Recovery, I've Decided that UbPorts isn't a good idea 4 me, But I'm Stuck or rather the Device is Stalled, But Not Bricked, Displaying the Google Splash Screen & Unlocked Padlock icon on the Black background. By Pressing the Vol. Down Key While Pressing the Power Button, I can Call the Menus, Power Off, Start, ReStart BootLoader, & Recovery Mode which of course Calls UbPorts Recovery that Offers 2 ReBoot System Now or Ubuntu Actions or Android Actions or ReBoot 2 BootLoader or Power Down or View Recovery Logs. if I choose View Recovery Logs & then Select Any of the /cache/recovery/last_logs I get the Orange Android Logo & it says installing Update, But it is in fact Parked Up!

Back 2 the Main Menu w/ the Green Robot Logo, Choosing Start Only Produces the Google Splash Screen w/ the Unlocked Padlock icon on the Black background. While ReStart BootLoader Loops back 2 the Green Robot again.

Choosing Recovery Mode as I said B4 does Nuthing, including Ubuntu Actions & Android Actions.

I'm Sorry I don't Recall if it is in Developer Mode, But I Can Categorically Confirm that I did have UbPorts 15.04 Running on the Subject if that's Any Clue. re the OEM UnLock I don't know if that's Associated w/ the UnLocked PadLock icon on the Google Splash Screen? & re the ADB Tools installed, I thought that was only Relevant 4 M$ Virus Bait! ie. Windows which is 1 of My Options along w/ MacOS 10.13.4 Hi' Sierra & Linux Mint 18.3

Yes I did Try the Above Link, which is the Russian Bride Chat Channel?

I Hope that Clarifies My Status & Provides the Required info 2 Solve this Nitemare. I'll Continue Researching the New Link that yoU Offered & the Magic Device Tools, But Please don't desert me,

Thanx Lakota 4 Replying 2 My Desperate SOS,... I did Sucksessfully install the Telegram App, But Alas the 1 & Only Channel Dealing w/ My Nexus 5 Hammerhead Device is in Russian! & I Reckon My Wife Will be Suspicious of Me Chatting w/ Russian Women?!? Surely there's Got 2 be Sumbody in this Forum that Can HELP Me Please....
