[Q] 1.29.401.16 to 4.19.401.8 Step by Step ? topic

I' using M7_U (801e) CID HTC_058
Out of the factory, it had HBOOT 1.54 and Firmware version 2.24.1136.2.

I SuperCID'd, and flashed 4.19.401.8 Firmware from here http://forum.xda-developers.com/show....php?t=2627416

and now with HBOOT 1.56.
And currently with ViperOne 4.3 Rom.

The situation is I'd like to have Stock 4.19.901.8 ROM
(not for warranty return, just to taste the Stock KitKat Rom
I'll still want my phone with BL Unlocked and SuperCID'd.)

I now have these required files in hand:

RUU Zip M7_UL_JB_50_HTC_Europe_1.29.401.16_R_Radio_4A.14.3 250.13_10.33.1150.01_release_318486_signed_2_4_dec rypted.zip (http://goo.gl/haCFs2)
OTA_M7_UL_JB_50_S_HTC_Europe_2.24.401.8-2.24.401.1_release_331108tottoh71qygw07hf.zip (http://goo.gl/274FYz)
OTA_M7_UL_JB43_SENSE55_MR_HTC_Europe_3.62.401.1-2.24.401.8_release_338160gxmo5sd9337kadux.zip (http://goo.gl/EOp9Iy)
OTA_M7_UL_K44_SENSE55_MR_HTC_Europe_4.19.401.8-3.62.401.1_release_34978069qunfn8klmohm8p.zip (http://forum.xda-developers.com/show....php?t=2627416)

The questions are:

Are these files exactly correct required ones?

Then how do I have to do to have Stock 4.19.401.8 Rom?

Lock BL > Flash 1.29 RUU zip > Flash 2.24 OTA zip > Flash 3.62 OTA zip > Flash 4.19 OTA zip > Unlock BL > Flash custom recovery ?

Thanks...
