Interop unlock using vcREG: Lumia Reg Editor (live/perm interop unlocking , full fs access) SD req’d

vcREG is a lumia registry editor that can access the registry as SYSTEM,so you can use it to capability unlock your locked and stock lumia or do other registry tweaks. Unfortunately, an SD card is required to bootstrap the app. It has been tested on quite a few devices, from a 520 to a 1520.
this tool uses low level RPC to gain access to the registry in a mostly unrestricted manner. it doesn’t rely on any third party code or libraries, its purely using windows functions. i’ve implemented reading and writing of Strings, Multistrings, DWORD and BINARY. Since capability unlocking can be tedious to do manually in a reg editor, ive created templates in the app that apply a predefined set of registry entries. So far, there are 2 templates in the app, with more to come. The first one is interop/capability unlock which unlocks all capabilities on the phone and adds some other ones i found poking around in manifest files. The second one is full FS access through MTP. I plan to add a .reg file importer hopefully in the next version if there arent too many bugs.

if you are already unlocked using the other method recently released, you can just sideload vcREG_1_1_SIDELOAD.xap, and use the app as a registry editor,or use its other functions from the all apps list.

if you are not already unlocked, you can follow the following instructions. here we will use the SD card trick to load the app in place of “extras+info”, and once we load the app, we will fire off the capability unlock. Once the phone is unlocked, we can restore our extras+info back, and sideload vcREG_1_1_SIDELOAD.xap so it shows up normally in the apps list instead of settings.

files you will need to have

– CustomWPSystem_0600.xap, you can grab it from Here or here

Download –  vcREG_1_1_BOOTSTRAP.xap

1.If extras+info is already installed, set your date 100 years ahead, and try to open Extras+Info from settings. It will give you a popup and let you uninstall it, so uninstall it. Now that you’ve uninstalled it, go back and change your date back to the current date.

2.Deploy CustomWPSystem 0.6 to phone memory from your PC. make sure it doesnt install to sd card but on the phone(settings->storage sense->store new apps on my phone).

3.Copy vcREG_1_1_BOOTSTRAP.xap to the root of your sd card. DO NOT DEPLOY OR INSTALL IT,just simply place this file there

4.Go to settings->storage sense->store new apps on my SD CARD. Now all app installs will go to sd card.

5.Open CustomWPSystem

6.Click the red SD Card permissions button, tap “sd card” then hit the check mark. The red button will now be green if everything went smoothly.

7.Under “select target app”, choose “Extra & info”, then click download from store. It will take you to the windows store page for “extras+info”. Hit install, and when its done installing, click back a few times to go back to CustomWPSystem the way it was.

8.tap “select the xap” and the filepicker will come up. tap “sd card”, then tap “vcREG_1_1_BOOTSTRAP.xap”

9.tap “Apply XAP”.

10.When the operation completes, go to settings and scroll down. You will see an entry that looks like this “D:WPSystemApps{2377fe1b…”, click it, and vcREG should open.


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. Once completed, you can remove the app and put extras+info back, and then you can sideload vcREG_1_1_SIDELOAD.xap to use the app normally from the all apps list.

After applying the full fs access template, you need to reboot before the access is granted. be careful not to brick your device by playing with the wrong files. the windows folder is wide open,so be wise.


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.


just try to deploy dummy.xap that’s attached below with wp power tools,and it will fail, but at the same time it will delete the app from the phone. now you can install extras+info again from the store


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.
