I tried 4 times to upload the sys files to PPCGeeks FTP, but failed. I have to choose the fs2you again, but it need raysource installed, I am sure it is safe, you need not worry about that. Many peoples are using fs2you.

Please note the 19701OS files are only the core files, if you already have an ENG WM6.1 Kitchen, you just need replace the same files and RGU.
For the OEM folder, you must use the REV.A from Alltel new ROM, it is important.
