Can anyone verify that Android 4.1.2 Blur_Version.98.30.1.XT907.Verizon.en.US from the defunct sbf site == from drdevs FXZ site? MD5s match perhaps?

it was Locked and Unrooted, but with the help of kingoroot and Motopocalypse I rooted and unlocked the BL.
I tried to downgrade to 4..0.4 on my Motorola Droid Razr M using RSD lite and kept getting a downgraded security version update gpt_main version failed error.
and I tried to downgrade to 4.1.2 using RSD lite , reboot more and more and not power up the phone and remain in the motorola logo.
any one have soloution for my problem?
RSD lite 6.1.6
version 183.46.10

Don't know why you're doing it? You have an unlocked KK BL, right? Flash the twrp recovery, wipe it squeaky clean from it and install a deodexed and debloated stock rom. Very reliable!

I see no reason to downgrade even for users 'stuck' with a locked bootloader. KK rom is better in every respect, except one. I really miss the stock camera on Jb.. it was insane 'quality' considering such a lens. Photos usually turned out real good.
