[iOS 11+12] Please fix cydia-no-network error for China devices

laoyur opened this issue 6 years ago · 59 comments

Hi, you may not know the fact that iOS asks network permission for an app when it get the first launch on all China device models. Network for that app is not available until user grant the permission.

However, with some reason, after the initial JB, Cydia just get no chance to show that alert. Users can not even find Cydia item in Preferences app. As a result, Cydia just not work after the initial JB.

A workaround is to delete some Network Extensions files or using a VPN to bypass, but that's very tricky and dirty.

The best method is to call AppWirelessDataUsageManager(link to /System/Library/PrivateFrameworks/Preferences.framework/Preferences) for Cydia explicitly.

code for iOS 11:

NSString *cydiaBundleId = @"com.saurik.Cydia";
[AppWirelessDataUsageManager setAppWirelessDataOption:[NSNumber numberWithInt:3] 
                                      forBundleIdentifier:cydiaBundleId completionHandler:nil];
[AppWirelessDataUsageManager setAppCellularDataEnabled:[NSNumber numberWithInt:1] 
                                       forBundleIdentifier:cydiaBundleId completionHandler:nil];

code for iOS 12:

        Class K_PSAppDataUsagePolicyCache = objc_getClass("PSAppDataUsagePolicyCache");
        PSAppDataUsagePolicyCache *cache = [K_PSAppDataUsagePolicyCache sharedInstance];
        [cache setUsagePoliciesForBundle:@"com.saurik.Cydia" cellular:true wifi:true];

and the entitlements required for iOS 11 & 12:

 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
 <plist version="1.0">
     <dict>
         <key>com.apple.CommCenter.fine-grained</key>
         <array>
             <string>cellular-plan</string>
             <string>data-usage</string>
             <string>data-allowed-write</string>
             <string>preferences-write</string>
         </array>
         <key>platform-application</key>
         <true/>
     </dict>
 </plist>

The code is required to call only once after the initial JB.
Could you guys consider adding that piece of code?

Answer 1 · 2018-12-06T06:49:08.000Z

大神说的没错，我最开始从Electra Rollectra，再用Unc0ver越狱，更新过两个插件后，Cydia就没有联网权限了，只能通过ConditionalWifi3来打开，确实这是个问题。如果Pwn能解决就方便了。

Answer 2 · 2018-12-06T08:34:23.000Z

非常棒的解决方法你能fork一下unc0ver并且将其添加进去吗

Answer 3 · 2018-12-27T07:30:20.000Z

go to /Library/Preferences/, remove com.apple.network*.plist, reboot your device and JB again, Cydia should be able to have internet. This is a workaround for China Models.

README before you try this on iOS12:

Since someone starts acting like a kid giving down thumbs only because my workaround does not work on iOS12..(if you really see the date I post this workaround, there was even no iOS12 JB yet), the workaround I mentioned is only tested on pre-iOS12 devices. and here's a free new workaround for now: buy a non-China model.

Answer 4 · 2018-12-27T07:34:20.000Z

@liuxuan30 thanks, but we are talking about solution rather than workaround here

Answer 5 · 2018-12-27T08:13:53.000Z

I understand that. and above is just FYI. I hope it can be fixed as well.

Answer 6 · 2019-01-02T01:29:57.000Z

@laoyur I just tried a new phone, it seems my workaround is not working. any idea?

Answer 7 · 2019-01-02T01:47:39.000Z

@liuxuan30 I don't know, the workaround itself is very tricky :(
I will consider forking unc0ver later when I have spare time.

Answer 8 · 2019-01-02T02:00:34.000Z

after trying reinstall Cydia and deleting those plist several times, it worked again... weird.

But I strongly support you and @pwn20wndstuff and maybe @saurik can help add this. It has been painful for Chinese devices!

Answer 9 · 2019-01-23T02:49:26.000Z

@Cryptiiiic what more info you need? I'm intersted in this

Answer 10 · 2019-01-23T05:25:58.000Z

@liuxuan30 pwn doesn't fully understand what this is, neither do I.

Answer 11 · 2019-01-23T05:32:22.000Z

@Cryptiiiic
Cydia cannot use WLAN/4G after JB on China devices.
Users need to use VPN or other ugly workaround to bypass.
if you can call AppWirelessDataUsageManager related API for Cydia's bundleid after initial JB, this problem can be fixed gracefully.

Hope you can understand now. :)

Answer 12 · 2019-01-24T01:32:34.000Z

@Cryptiiiic @pwn20wndstuff So let me repeat what @laoyur said from an user perspective:

The iPhone sold officially in mainland China has a special feature since iOS 10.3, that when you first time download the app and open it, iOS will prompt a popup to ask you do you wish to allow the app to have internet access. Some iOS built-in apps will also have this popup, like calendar ( I guess they are those apps can be delete and reinstall from AppStore).

Here are some screenshots to help you understand:
1. first time open an app, e.g. the calendar:

2. in settings -> WLAN, there is a page to list all apps using WLAN & cellular:

3. if you click:

this is my dev machine, the DPIHelper is my app. You can see there are AppStore and Settings. I didn't launch calendar app here for the first time when I capture this, so you won't see it. But I have launched Cydia and make it work, it still not shows Cydia.

4. and if you choose Settings:

So this is how it looks and functions. I was told this feature is dedicated only for mainland China because laws demand this. It seems like the iOS is reading the iPhone's hardware info to decide if the phone would have this feature. Only devices with Cellular are impacted. I have WIFI only iPad, which is fine. But I didn't have a cellular iPad, so I cannot confirm whether Cellular iPad has this feature.

About Cydia:

If you open Cydia for the first time, it will not have the prompt, nor the internet access. It's not even shown up in the above settings. Just like a ghost. I'm gussing it's because Cydia is installed in /Applications rather than the AppStore apps path in /var/mobile/...

The current workaround I'm using is to JB and ssh into the device, delete all com.apple.network*.plist in /Library/Preferences and reboot again. Then Cydia will have access to internet, but still not showing up in the settings list.

Note if you upgrade the Cydia bundle, it will be blocked again, and you have to repeat above steps to make it work again.

Hope this can help you understand.

Answer 13 · 2019-02-07T10:38:16.000Z

Yep. Can confirm all Chinese devices have this issue. Just FYI an indication that the device is a Chinese one is if you go to Settings, in the section where it should say “Wi-Fi”, it shows “WLAN” instead. Also if the device is SIM-compatible, let it be an iPhone or an iPad, in the tab Cellular it gives you the option to choose whether an app can use WLAN or both.

Source: have an iPhone purchased in China and looks like all iDevices whose serials end with CH/A have this problem.

Just want to add that if your device has this issue, using a VPN app that sets up a SOCKS server on localhost may help (possibly). It has to be on localhost so it won’t work if you add a VPN configuration directly in Settings.

Dunno why but /var/preferences/com.apple.networkextension.cache.plist seems to have something to do with it as well. My workaround when this was troubling my iPhone 5S on yalu used to be to SSH into the device first and then rm -rf /var/preferences/com.apple.networkextension.cache.plist, reboot and dang, everything worked. And when this is happening again on unc0ver I was like bugger it and boom, it works. So maybe anyone of greater knowledge than me can look into that file to see what’s going on (not sure whether it’ll be present on non-Chinese devices as well tho).

Answer 14 · 2019-02-11T01:57:33.000Z

I don't believe it has been resloved under WIFI without any reply from Saurik nor the authors.

Answer 15 · 2019-02-17T13:36:24.000Z

Encounter the same issue here on my Chinese Models of iPhone X.
All apps run as root involved.

Answer 16 · 2019-02-19T13:29:06.000Z

Get a VPN and then try it see if it works
If it doesn’t move out of China

Answer 17 · 2019-02-23T06:07:20.000Z

Code for iOS 12 updated.

We can make a NetworkFix.deb and people can scp it to the device and then exec for Cydia.
But I do hope unc0ver can embed the deb as built-in resource and call NetworkFix for Cydia during initial JB.
It will help a lot of ordinary people living in China.

Tried this method with the latest release on iOS12, didn't work.

Answer 19 · 2019-03-07T19:38:21.000Z

This seems to be the oldest open issue as of now but still unresolved after several months.

I confirm the problem still persists with iOS 12.1 on iPhone 6 with unc0ver v3.0.0%b42.

Symptoms: Cydia does not connect; network permission dialog does not pop up; no "Cydia" in network settings (under Cellular where you can assign network access for apps).

What is worse is that the removing plist trick does not work either @JQ555888.
By "no working" I mean, after deleting those files (and with or without rebooting) --
Cydia still fails connection;
Network permission dialog still does not pop up;
Cydia is still not in network settings so I cannot allow it manually either.

Tried multiple times, no luck.

Installing @laoyur Network Fix deb files does not seem to have any effect either (his fork of unc0ver does not support iOS 12 so I tried to install the deb file with dpkg).

Answer 20 · 2019-03-07T19:40:10.000Z

Restoring network settings does not seem to have any effect.
Reinstalling Cydia does not seem to have any effect, even combined with deleting the plist files or restoring network settings or installing @laoyur deb file.

Answer 21 · 2019-03-07T23:45:53.000Z

@bfrggit the deb in my fork is for iOS 11 only -- I haven't update it with iOS 12 support
I will upload a new version later.

Answer 23 · 2019-03-08T03:16:15.000Z

@bfrggit downthumbing me is no sense and won't help anything. The time I comment on the workaround is way before an iOS12 JB POC. I didn't say it would work on iOS12 - it works on iOS 10.3 and iOS 11, though it's sad to find out this.

this is ONLY for China sold iPhones, so I assume you have one if them. If you are in the US, the easiest way is to buy a US model.

Answer 24 · 2019-03-08T09:37:16.000Z

@bfrggit
com.laoyur.network-fixer.deb.zip

try this one and feedback :)
remove the .zip file extension before install with dpkg
usage: NetworkFixer com.saurik.Cydia

It worked for me.

I downloaded the new file and renamed it to remove ".zip".
I SCP-ed it onto the phone.
I installed it with dpkg -i.
I then ran the command exactly as @laoyur said; note "Cydia" has capital C.
Then "Cydia" appears in the list of apps under network settings, and WLAN + Cellular are enabled for it.
Cydia works.

@hyl946 Did you try exactly these steps too? What is the output of command NetworkFixer com.saurik.Cydia?

Edit:

For @hyl946 I am on 12.1 instead of 12.1.2 so might be different?
I cannot really help you debug with the output of the command but I noticed that there were some relevant info there when the command runs... (I did not screenshot sorry...) But the author might be able to help if you provide more details.

Answer 25 · 2019-03-09T05:07:39.000Z

uploaded a new deb with a postinst script which should auto call NetworkFixer for Cydia during installation.

com.laoyur.network-fixer-0.1-2.deb.zip

usage:
0. download com.laoyur.network-fixer-0.1-2.deb.zip 👆, and then rename to com.laoyur.network-fixer-0.1-2.deb(remove the .zip part)

scp deb to your phone
install
enjoy Cydia :)

Answer 26 · 2019-03-09T13:41:41.000Z

Just FYI, apps installed from Cydia can encounter the very same problem, say, Flex 3.
One solution is to get package name from app's Info.plist (might need to convert to xml by plutil in case of bplist), and then run NetworkFixer package.name provided by @laoyur.
Probably not the best way to do it but oh well.

Answer 31 · 2019-03-12T04:35:36.000Z

@laoyur 's method works just fine on iOS 12.1.1~12.1.2, across my Chinese region devices, should forget about deleting those plist files.

Answer 32 · 2019-03-12T04:51:40.000Z

@Hdot1 so essentially it’s a way to copy files from your PC to your phone via SSH (secure shell) and “scp” is the terminal command to do so. “deb” stands for debian package and it’s the installation file format for jailbroken iOS used by dpkg. You can switch to a graphical interface by using apps like Cyberduck (if on mac) or WinSCP (Windows). Both should do :)

Answer 33 · 2019-03-12T04:56:47.000Z

@JQ555888 so I download WinSCP, connect my iPhone to my pc and paste ‘https://github.com/pwn20wndstuff/Undecimus/files/2948085/com.laoyur.network-fixer-0.1-2.deb.zip’ into the WinSCP??

Answer 34 · 2019-03-12T04:59:05.000Z

@Hdot1 if you have Filza installed, you can upload deb via webdav, and then install the deb in Filza

Answer 35 · 2019-03-12T05:02:50.000Z

@laoyur do I download Filza off safari? What’s webdev?

Answer 36 · 2019-03-12T05:03:37.000Z

@Hdot1 actually you don’t have to connect your phone to the PC; just make sure it’s in the same network as your PC. Also you’ll need to get your phone’s internal IPv4 address, and in WinSCP use that IPv4 for host, “root” for username and “alpine” for password so that the client can correctly identify the host

Answer 37 · 2019-03-12T05:06:48.000Z

@JQ555888 IPv4? So once the host has been identified I just paste that code into it or something?😂

@Orgmist
1- Down File .deb

2-CSP .deb file into the var/mobile path (in fact, anywhere)
2-Use WinSPC no wifi or iPhone Tunnel (Terminal) to Console (shortcut Ctrl + T) and then type the following

3-command:
dpkg -i filename.deb

For example install the application
abcde.deb
dpkg -i abcde.deb

4- Reboot machine -> enjoy Cydia
