2. Install HERE Maps (microsoft.com/en-us/store/p/here-maps/9wzdncrfhw6b) from the store, and move it to sd card. Download installation file manually ( wpsnitch.appspot.com ), if you want to install it from SD card.

5.Extract Install.zip from below , and put the extracted "Install" folder on the root of your sd card. The Install folder should have 4 files in it.

12.Navigate to D:\WPSystem folder and rename Apps1 back to Apps

13. Navigate to the root of your sd card. Get into "Install" folder we put here earlier. Choose all 4 files from there to Copy.

16. After you apply the unlock, you can sideload vcREG_1_2_SIDELOAD.xap to have the app available in your applist for future use.

Q&A

HOW TO USE THE APP TO CAP UNLOCK

now that the app is open, you want to unlock all capabilities. hit the app bar, and tap "templates". here we see two options, interop/caps unlock, and full fs access through MTP. check your options, and click apply. Reboot for MTP.

HOW TO USE THE REGISTRY EDITOR

the main registry editor is pretty straightforward. put the correct path, the key name and value if its a write.

string: it will read as one string. writing is the same,write a string, no spaces, hit write

multistring: multiple strings are read as strings separated by spaces. to write multiple strings, separate each string by a space, hit write.

dword: it will read as 8 characters of ascii. so a value of 1 will read as 00000001. writing is the same. you MUST write 8 characters or it wont write it,so a 1 is 00000001 and B0000 is 000B0000. all bytes are hex, not decimal.

binary: when you read, the app will return 20 bytes, regardless of how long the binary is. if the whole binary sequence is 11 22 33, it will read as 112233 and then 17 00s. the reason for this is that there isnt a method to know how long the binary sequence is,so i hardcoded it to read 20. even if its longer than 20 bytes, you will only get 20 bytes back. i can up the limit at a later time if its something people need.

writing binary is also limited to a max of 20 bytes. if you are writing less than 20 bytes though, dont put the extra zeroes. if you are writing 4 bytes such as 11 22 33 44, then simply write it like this 11223344(no spaces) then hit write.

DO THESE REGISTRY CHANGES PERSIST AFTER A HARD/FACTORY RESET?

no. if you hard reset, you will revert back to the stock rom and any changes you made to the registry will be lost. you will have to make the changes again after a hard reset. file system changes, especially in the windows folder can persist though.
