[chirp_users] Baofeng UV-5R Frequency mod

I would like to open all the frequencies on my Baofeng 
UV-5R to allow me to program in from 10MHz-999MHz in 
the  CHIRP application. I understand most of not all of 
these frequencies will not work but it might give me a few 
extra frequencies around the working bands.

Bench testing has shown the actual  transmit range of an 
expanded 150/450 MHz UV-5R to be:

     VHF range 136 - 174 MHz   expands to   127.8 - 176.0 
     UHF range 400 - 520 MHz   expands to   383.5 - 524.3 

Outside of that range, the radio would either not transmit 
or was unstable.
Receiver coverage drops off sharply to zero outside the 
factory specified range.

I followed the instructions below from: Baofeng UV-5R: 
Extreme Receive Modification: (Web URL Link Removed)

1) Open the library.zip file located in your C:\Program 
Files\CHIRP\ directory  (location may slightly differ 
based on your flavor of windows, but you get the  idea).
2) Enter the Chirp folder inside the library.zip
3) Delete the  UV5R.pyo file from the zip
4) Add the UV5R.pyo file (if it's named uv5r.pyc,  rename 
it to .pyo before placing it in the zip file)
5) Save the modified  library.zip
6) Open chirp and on the radio selection popup, select the 
Vendor  "Baofeng Hack"
7) Program your radio as desired (be aware of the radio 
chip  limits)

I was able to download the UV5R.pyo file but 
cannot  locate the  library.zip file located in the 
C:\Program Files\CHIRP\ directory.  Has the library.zip 
file name changed or has the Chirp been  programmed to not 
allow for this modification anymore?  Could someone send 
me the library.zip or the new file or tell me how to 
make  this Baofeng UV-5R Frequency mod?

Thanks, Tom
