Hi All

I have the Hong Kong Note 4 N910U
PDA N910UXXU1AOC3
CSC N910UZZH1AOC3

As you may know, lollipop 5 is not out yet for this particular version. As I am experiencing some issues with the phone, I thought I'll just do a factory reset. However I've read somewhere here that I can use the other stock roms of the N910U eg; Taiwan 5.01 or New Zealand 5.0.1. So I thought I might aswell update to lollipop and then do a fresh factory reset.

So I downloaded this Taiwan one
PDA N910UXXU1BOD4
CSC N910UZZT1BOD4

However it keeps failing in ODIN.

I did use all different versions of ODIN, tried on different usb ports, re-installed installed new drivers, used a different computer etc.. Still same outcome. I am using the original usb cable that came with the phone. What am I missing, any help will be much appreciated ?

When my phone trying to update official 5.0.2, it appeared a red triangle and exclamation mark. Then, the phone become a brick. It can only access fastboot and recovery mode now. I unlock the phone and try once more, it still failed. Also, i tried to use RUU 5.0.2 and 4.1.2, it also failed. I can't find any RUU is for 4.4.3 HK ver to try.
My phone now unlocked, S-ON, HBOOT-1.61.0000, unroot
I can do nothing now. Does anyone can help my? Thank You.:(:crying:

Who knows a store in Hong Kong, that has the LG G4 in stock today?
