PSTV & Vita only!

There has been some amount of confusion regarding how to do this, as well as what I consider undeserved FUD, so I decided to create a post with detailed instructions. Follow these directions carefully. As with all console hacking endeavours there is a possibility that things can go wrong and there are no guarantees implied or otherwise that you will not get banned or break something. YOU WILL LOSE SAVES & PROFILE DATA IF YOU DO NOT HAVE A BACKUP. So do create backups first.

This short guide is adapted from the original Russian tutorial found Here. Also, thanks to u/kiru2488 who seems to be the first person to bring attention to it in the english speaking scene, and who I first heard of it through his post Here.

IDU mode WILL begin system updates WITHOUT WARNING or any prompts at all if the PS4 is connected to the internet. Disabling Internet capability is VITAL.
Back-Up your user data, if you can isolate figure out what causes data loss in this process, please contact me via DM or @ Reddit in r/PS4homebrew (u/fuctface)

Spoiler: PREPERATION

You will more than likely lose your Save and Profile Data if you haven't yet made backups!

1. Remove all USB devices from PS4.
   
2. Make sure you are able to run payloads via cache mode with network disabled (or use offline method).
   
3. Exit to the main menu and select "Profile" -> "Change User".
   
4. In the "Name" field, change the name of your user to "User1".

Spoiler: ENTERING IDU MODE

1. Power on the PS4. Go to "Settings" -> "Network" and make sure the "Connect to the Internet" is left unchecked.
   
2. Go to your browser (or user guide if applicable) and launch the "HEN" payload.
   
3. Go to "Settings" -> "Debug Settings" -> "System" -> "IDU mode", select "On"
   
4. Click "OK" to reboot.
   
5. Wait until you see "Provide unit with a valid network connection or insert IDU update disc" in the upper right of the screen
   
6. Turn controller back on and hold (R1) + (R2) + (L1) + (L2) + (Option) + (UP) until "Staff Mode" is enabled.

Spoiler: ENTERING REMOTE PLAY

1. On your PS4, go to "Settings" -> "Remote Play Connection Settings" and check the box that says "Direct Connection to PS Vita / PS TV System".
   
2. Next while still in "Remote Play Connection Settings" choose "Add Device".
3. On the device you wish to use remote play on (Vita, PSTV, PC) start the Remote Play/PS4 Link application.
4. On your Vita/PSTV, create a new (direct) connection to the PS4 and enter the pairing code on the Vita/PSTV.

A new user will be created, "User2". Do not delete this user or you will also disable Remote Play for the other profiles.

Spoiler: EXIT IDU MODE

1. Run "HEN" if "Debug Settings" is unavailable under system settings.
   
2. Go to "Settings" -> "Debug Settings" -> "System" -> "IDU mode" and choose "Off" to disable IDU mode.
   
3. Click "OK" to reboot.

A Note on PC Remote Play: I do believe it is possible to get it to work, but you need have both PC and PS4 connected to an access point without internet. A router with the WAN cable unplugged or a similar setup. I have had some success with connecting both PS4 and PC to an ESP8266 flashed with a localhost exploit server. You may also need an older version of the Remote Play application. I don't have anymore time to work on this today but I hope to get it going and I will detail it in a later post.

Spoiler: ADDENDUM: Daripa has shared some instructions for those with Unactivated Vita's

For those of you who do not have psn on the vita 3.60.
copied from my post at wololo

First install netcheckbypass on vita/pstv
create a psn account on pc

1. set Henkaku DNS (or use vitaupdateblocker)
2. install registryeditor
3. navigate to /config/np1/ and make sure the keys for your email and password blank
4. install uricaller
5. open uricaller and call the uri “psnreg:”
6. if you have HenkakuDNS or Vitaupdateblocker running the app will just work
7. Sign into or Create your PSN Account
Press done and the app will auto-exit and assign your account to the system

On the ps4 as per the Russian site

1. Remove all USB devices from PS4.
2. Make sure you are able to run payloads via cache mode with network disabled (or use offline method).
3. Exit to the main menu and select "Profile" -> "Change User".
4. In the "Name" field, change the name of your user to "User1"

Keep in mind i lost all my save games. Some people claim they don't lose them however. Make a backup just in case.
5. Power on the PS4. Go to "Settings" -> "Network" and make sure the "Connect to the Internet" is left unchecked. I turned off my internet on the router.
6. Go to your browser (or user guide if applicable) and launch the "HEN" payload.
7. Go to "Settings" -> "Debug Settings" -> "System" -> "IDU mode", select "On"
8. Click "OK" to reboot.
9. Wait until you see "Provide unit with a valid network connection or insert IDU update disc" in the upper right of the screen
10. Turn controller back on and hold (R1) + (R2) + (L1) + (L2) + (Option) + (UP) until "Staff Mode" is enabled.
11. On your PS4, go to "Settings" -> "Remote Play Connection Settings" and check the box that says "Direct Connection to PS Vita / PS TV System".
12. Next while still in "Remote Play Connection Settings" choose "Add Device".
13. On the device you wish to use remote play on (Vita, PSTV, PC) start the Remote Play/PS4 Link application.
14. On your Vita/PSTV, create a new (direct) connection to the PS4 and enter the pairing code on the Vita/PSTV.
15. Run "HEN" if "Debug Settings" is unavailable under system settings.
16. Go to "Settings" -> "Debug Settings" -> "System" -> "IDU mode" and choose "Off" to disable IDU mode.
17. Click "OK" to reboot.

Do not delete USER2

You should mention that it’s possible to accidentally update in IDU mode.

I recommend update blocker, Al-Azif DNS in your router, or host offline, just incase.

Oh and it will wipe your saves, so back up everything.

If you follow this exactly it will leave the saves untouched. Step one is disable networking. I will add an extra warning about updates as it isnt at all obvious that IDU mode does system update without any prompts.

I have had reports that even renaming accounts to user1 saves still wiped.

I don't think there were clear instructions until now. They were posted in Russian on one site, and the Reddit thread that people were using didn't have detailed instructions, it was only 3-4 lines so I think anyone who was brave enough to try it was playing it by ear mostly. I also lost all my saves etc the first time I did it. But I just went through each step as I wrote this guide and my userdata is safe this time around. I think I know what my mistake was, but that's not really relevant.

Cool, well once we have more confirmation I will definitely condense this and add it to the AIO guide.

 

[DayVeeBoi]

Feel free to do so. I have heard of 2-3 people losing their save data that did not follow this method, but I have also seen about 2-3 other reports of saves being okay. I am not disregarding your input, I have been using this for about or so, and have gone through the steps twice myself. I am aware that it's quite possible to lose save data or be updated in IDU mode but I am pretty confident that the tutorial is succinct enough that following the steps shouldn't be too hard and if the steps are followed I don't think there will be any problems, but peoples actions never surprise me.

 

[KiiWii]

@DayVeeBoi asking around @Broka added that you should include:

“All PSN activated profiles will be wiped, along with any linked saves”

You're correct, there is some other factor happening here. I'm not going to be the one to try and isolate it, but I just went through the process again and this time my profile is gone. I'm not going to be the one to try and isolate what the problem is or debug it (at least not today as I have things to do) but definitely just following this guide to a tee is not enoubh to save profile data.

Also:

Regardless if you rename the profile via ftp/online.json (PSN profiles do not have the luxury/ability of being manually renamed, as non activated profiles do)

Does this work on an unactivated Vita?

No, but I am pretty sure that Yifan created a homebrew that does that although I can't recall the name of it ATM.

I've lost all my saves and trophies after using this method but DB SG Backup saved my ass. I think it could depend on the console's language. The default profile name in IDU Mode for me is Użytkownik1 (User1 in polish) and maybe if I changed my main profile name to it's polish equivalent in IDU or console's language to english it would work properly.

Yeah thats possible. I actually adapted this tutorial from a Russian site and just used google translate. It's possible that something got lost in translation as well. It seems like the loss of profile data is consistently inconsistent. Hopefully we can iron it out over the next few weeks and save people some headaches.

 

[DayVeeBoi]

What do you guys think, should I see if the mods will move this to the Vita section? It seems like it has more relevance there than here considering this method only works on Vita/PSTV ATM?

 

[Broka]

@DayVeeBoi works on pc as well (RemotePlay ver 2.6.0.02270, patched with MysteryDash' offline patch)

Oh cool, thanks. I assumed it would work with a little finesse. I just wasn't positive, so thanks for confirming it and letting me know about the patch. There are a few ppl on my reddit thread asking about using it with PC.

 

[windhazard]

Will definitely try this. But what's the point of yellow texts?

 

[DayVeeBoi]

Well they're pretty clear. They mean exactly what they say in them. And the obvious intention is to highlight important parts of the text. Are you unfamiliar with highlighting? Bold and underlined text also serve the same purpose, although without a cautionary connotation that is clearly warranted in this context.

So, this really works? You dont need to connect your PS4 to the PSN network (just FOR ONCE) with IDU mode?

I know that if we go the normal/legit route without IDU mode, hacks etc. that its nesssary to connect the PS4 atleast one time to the PSN netowork to be able to link it with the PS Vita console (to unlock the Remote Play settings on PS4).
