Forced Windows 8.1 Update 2 Install On Lumia 635 RM-1005 (SKU:S561A)

Hello folks! It's a pleasure for me making this thread.
So 2 week ago i swapped my Lumia 635 from SP because my old 635 died on my pocket without unknow reason :( sh*t i miss my phone, but know i have a new one and trying to stay ok with my phone installing apps, updating i just figure out i've missing features on my phone, like equalizer, factory reset protection, denim update and much more things, so i started checking info on internet, searching why my new one do not have these features, its a shame.

At least all lumia 635 are getting denim but this Lumia its getting only updated Extras and Info App with denim flag, why this Happens?

My old Lumia 635 wih SKU 6599A have Firmware 02173.00000.15154.50010 so this is the POSTPAID AT&T Device
and My New Lumia 635 with SKU 6561A have Firmware 01061.00070.14246.29017 and this is the PREPAID AT&T Device.

AT&T is not updating PREPAID devices? it's okay :evil: we don't need them. :grincry: :grincry: :grincry:
