1) Send yourself e-mails with the following support_uri(s) as links:

2) Open your E-mail App on the Vita, wait for the mails and click on the link in the first mail

3) Now just type in your e-mail address and send back this e-mail with the registry file as attachment. You will notice the E-Mail app close itself, thats normal and supposed to happen! :)

4) Do the very same thing for the second mail

5) Retrieve both dumped files with your PC's e-mail client and just leave them on your desktop for now..

7) Download fixreg_vita 0.1 if you haven't already and extract the archive.

8) Now we are going to just drop our registry files next to the fixreg.exe

9) Run the fixreg.exe the first time

10) It should create a seg-folder for the various segments

11) Okay! Now just open the system.dreg with any Hex Editor of your Choice.

Just search for region_no via the search option.

Note: The offset varies depending on your Firmware Version!

Region	Value	Region	Value
/	00	Hongkong	08
Japan	01	Taiwan	09
America	02	Russia	0a
Europe	03	/	0b
Korea	04	/	0c
United Kingdom	05	China	0d
United Kingdom 2	06	/	0e
Australia	07	/	0f

12) Change said value to whatever region number you like and save.

13) Now once again run fixreg.exe so that your changes get patched and the checksum is valid for the Vita

The system_.dreg file is our patched registry file which we can now write back..

14) The very first thing to do now is to simply rename the 'system_.dreg' file to '#0' without any file-ending!

15) Now we are going to write a new e-mail with the #0-file as attachment and the path we want the file to be installed (vd0:registry/system.dreg) as Subject. Send it to your vita!

16) If everything did go right you should see a camera symbol. Touch it and DO NOT click OK on the appearing Error Message but simply close the e-mail app completely!

17) Restart your Vita! Done!

1) Install CMA/QCMA if you haven't already and make a full backup of your Vita.

2) Find out your AID (PSN Accound ID). You can simply find it inside CMA's file structure once you backed up your system. PSVita/SYSTEM/xxxxxxxxxxxxxxxx/

3) Now visit http://cma.henkaku.xyz/, enter your AID there and copy the generated key.

4) Next up you'll need to download PSVIMGtools for your OS and extract it somewhere.

5) Now copy the .psvimg backup file from your CMA folder next to the just extracted psvimgtools.

6) Run the following code via terminal.

7) You can now obtain your registry backup file from /output/ur0_tmp_registry/registryBackup.txt

8) Okay! Now open the registryBackup.txt with any Hex Editor of your choice.

Just search for region_no via the search option.

Note: The offset varies depending on your Firmware Version!

Region	Value	Region	Value
/	00	Hongkong	08
Japan	01	Taiwan	09
America	02	Russia	0a
Europe	03	/	0b
Korea	04	/	0c
United Kingdom	05	China	0d
United Kingdom 2	06	/	0e
Australia	07	/	0f

9) Change said value to whatever region number you like and save.

10) Run the following code via terminal.

11) Copy back all created files in your output directory back to your CMA System folder

/PSVita/SYSTEM/xxxxxxxxxxxxxxxx/

12) Update the QCMA Database or simply restart CMA to find the changed files.

13) And finally restore the backup back to your Vita

Done!
