I did not install the stock rom. I was running Liberty RC1 (i think that is what it is called) and wanted to come back to Th3ory. I backed up all apps with titanium and did the whole factory reset and all of the wipes. Then i installed the R3Blurr3d 2.0 and the system version I am sitting on now is 5.5.893.XT875.Verizon.en.US. From what I understand he built the rom from the "Leaked" Cheesecake. I could very well be wrong... but I don't think you need to Install the "stock" leaked rom unless you want all of your blur back. I did however do the whole "forever Root" thing.
Actually the reason for the leaked ROM install is for the radios and battery lasting. The ROM is based off the update but no radio update.
