How to install custom rom on 4.5.141?

[johnny13oi]

Hey guys, I have an Atrix with stock 4.5.141 and was wondering how do I install custom roms?

Huge warning here:
http://forum.xda-developers.com/showthread.php?t=1501532

that says to never flash SBF files which seems like I have to do to make the device unlocked so that custom roms can be installed so what do I do?

I see this automatic unlocker: http://forum.xda-developers.com/showthread.php?t=1182871&page=88

But it just seems like a scripted program that runs what I am not supposed to do on 4.5.141.

I just want to make sure everything is alright before I proceed and end up with a brick.

johnny13oi - This is all you need to do on .141:
Flash this - http://dl.dropbox.com/u/34025287/4547-fix-try2.sbf using RSD lite, 5.3.3 or higher will work fine
Its the pudding only - not the full service sbf. Its only the unlockable bootloader. Flash that and then flash RomRacer's latest CWM - load your ROM of choice onto your internal SD card and flash it. Simple as that.

Thank you so much for your help. Can anyone please confirm these instructions? It just seems like the very thing that the warning post said not to do so I am just worried.

I can 100% confirm that this works for 4.5.141

I unlocked my device using this method. It was simple and painless. However, you will have to re-root if you are already rooted. If not, you'll just have to root after!

Johnny if you're that paranoid about it - then modding your phone isn't for you.... That isn't an actual sbf file i linked you too - its only the bootloader..... you WONT brick.....

You just need to finish the process.

This is normal for gingerbread bootloaders and causes a lot of panic but just get into fastboot (which you wouldn't be able to do if you were hardbricked) and do the unlock process.
