Reverting M8 to ROM it came with

Storyline: I've bought Honda CRV 2016 with Connect system, it has mirrorlink integration, and I want navigation in my car badly.
What I've already tried:
1. Downloaded RUU_M8_UL_K444_SENSE60_MR_BrightstarUS_WWE_3.28.15 40.5_Radio_1.21.21331147A1.19_2G_20.63.4196.01_rel ease_394319_signed_2.exe (and many other .exe RUU instals)
It reverts my 6.12.117.4 to 3.28.1540.5 but when i click Next it fails during sending process

2. Downloaded stock 4.4.4 RUU_M8_UL_K444_SENSE60_MR_BrightstarUS_WWE_3.28.15 40.5_Radio_1.21.21331147A1.19_2G_20.63.4196.01_rel ease_394319_signed_2.zip

Connected phone in fastboot, then
fastboot getvar all

Code:
