Both occurrences of the unique hex string pattern need to be modified accordingly to reflect a change in the pagepool. If you are only seeing one occurrence, my guess is the OS.nb or Ruu_Signed.nbh you are attempting to edit is not based entirely off of the Sprint Diamond WM6.1 stock rom (1.09). The first occurrence of the unique hex string pattern is located in S000 of nk.exe (device kernel). If this kernel has been hex edited or replaced entirely as part of a new XIP in the rom you are attempting to edit, then, more than likely, the pattern has been altered or removed entirely and only one occurrence will exist.

Hope this helps. Good luck.
