Default [Q] XT912 4.1.2 to 4.0.4 - is it possible?

Hi all! I have a question.
Is it possible to downgrade from 4.1.2 to 4.0.4 with no problems?

System version: 98.72.16.XT912.Verizon.en.US
Kernel version: 3.0.8-gbacb1cf hudsoncm@il93lnxdroid89 #1 SMP PREEMPT Fri Feb 1 20:59:31 CST 2013.
Build number: 9.8.2O-72_VZW-16
Rooted
Bootloader: Locked

Or i can flash any custom ROM using BMM or SS without downgrading and having any problems? I've read, that flashing another ROM with another kernel will cause some trouble.

And how to unlock bootloader?

Sorry if there was a similar thread!

Well, unlock boooader is not possible on this device. If you already flashed JB.xml via RSD Lite were isn't any downgrade sollution to ICS. You can flash Custom ROM via BMM without problems. Your ROM still can be JB, no need of downgrade to ICS. These ROMs seems to be so far stable for me.

I flashed and rooted Jelly Bean on my droid razr, that came with ICS, using DROID_RAZR_Utility_Jellybean_XT912_WinMacLin.zip. The Jelly Bean 4g and Wifi Radios are terrible compared to the Ice Cream Sandwich radios. So, I want to go back to ICS. Is this possible? Google gives kind of vague answers. If not, could you recommend JB custom roms with a good 4g radio? My phone is my only source of my internet.

There's only one custom kernel,JBX, available for RAZRs (AFAIK), and it is not compatible with stock ROM. You need a kexec based ROM for JBX kernel.
The latest configuration at present is KitKat ROM+JBX.

Plain answer, No, you Cannot downgrade. As for the custom ROMs, they've been working very good with LTE. You can try the CM 10.2.1 stable if you want to stick with JB.
My friend told me,there was life outside the internet and that I should check it out.
I said "Cool.! Send me the link. !!"
