Ansar. Your Signed Bootloader RUU works perfectly to Downgrade the Arrives Mango Bootloader from 4.3 to 1.25 as you supplied which worked perfectly to install the DFT HSPL #3 on the Arrive. Just want the headsup to be known so we can get some custom roms rolling on the Arrive. I have been dying for a fully unlocked device since release.
Maybe it is time to get back into Rom Cooking again... Hmm.
