Someone help me out ... I have a c6506, generic US. Completely stock on .101 firmware. I want to be stock w/ root. My bootloader is unlockable BUT I don't want to unlock it if I don't have to, because I want to keep DRM keys, etc. (I know all about Backup TA, but I would just rather not unlock it if I don't have to.)
One guy says I need to flash to .67, root, backup TA, let Sony upgrade to .101, unlock bootloader, flash custom kernel with recovery, flash SuperSU, restore TA.

Then another guy says I can just flash exploitable kernel FTF .423, use doomlords root exploit, flash Nut's dual recovery, then flash .101 kernel back. This is much easier but first guy says this will soft brick device.

So I'm looking at the flashable ZIP file and wondering if I can do this:
1. Use flashtool to return to stock 10.3.A.0.423
2. Root using Doomlord's tool
2a. (Backup TA just to be safe)
3. Flash Nut's dual recovery.
4. Flash the ZIP file provided in this thread
5. Flash the stripped FTF using Flashtool
Will that work?
