Can't update iPhone 3GS even to 6.0 (error 3194)


Recommended Posts

So after the problems in the previous thread i 'gave in' & decided to upgrade to v6.0.

Seems this also doesn't work. It wont let me do this & i get an error 3194 message. I'm receiving no carrier signal due to attempting to downgrade my baseband as per instructions on iClarified.

I just want to get my phone to work. Any ideas?

From looking around online it could be due to editing your hosts file.

Try this

Fix Error 3194

The fix is the same regardless of what operating system you are using:

  • Quit iTunes
  • Locate your hosts file, in Mac OS X this is /etc/hosts and in Windows this is c:\windows\system32\drivers\etc\hosts
  • Open the hosts file with Administrator privileges
  • Add the following lines to the very bottom of the hosts file:
  • 74.208.105.171 gs.apple.com
  • Connect your iPhone to the computer
  • Launch iTunes
  • Put the iPhone/iPad/iPod into DFU mode** by turning the phone off and then holding down the sleep and power button for 10 seconds, then release the power button but hold onto the home button until iTunes tells you that the device is now in recover mode
  • Use the iTunes Restore feature as usual with the iOS device

How to enter iPhone DFU mode

  • Connect the iPhone to your computer and launch iTunes
  • Turn the iPhone off (hold down the power button at the top of the iPhone)
  • Hold down the sleep/power button and home button together for exactly 10 seconds, then release the power button
  • Continue to hold down the Home button until a message appears in iTunes telling you an iPhone in recover mode has been detected

Does IOS6 even support the 3GS? Not sure.

Yes it does, which is because it was still officially sold shortly before the start of iPhone 5.

Does IOS6 even support the 3GS? Not sure.

Yes it does. Possibly the final hurrah for the 3GS.

So after the problems in the previous thread i 'gave in' & decided to upgrade to v6.0. Seems this also doesn't work. It wont let me do this & i get an error 3194 message. I'm receiving no carrier signal due to attempting to downgrade my baseband as per instructions on iClarified. I just want to get my phone to work. Any ideas?

Update your iTunes to the latest version (10.7), then perhaps u could do a full backup of your device and the restore it then upgrade it to iOS 6.

Technique: Error 3194 search on Apple's Website says that access to gs.apple.com may be getting BLOCKED by your PC or Mac's Firewall.

Well i have fixed it, sort of & now i really don't like my phone.

What i did was pretty simple in the end ....... Settings>General>Reset

Then i selected to reset the settings but not the files. After this i TRIED resetting the entire phone but it just had a spinning circle for an hour. I shut the phone down & restored via iTunes & it finally allowed me.

So now i'm running iOS6 & i really don't like it.

The phone is no longer jailbroken. I have no idea if an untethered jailbreak is available or not for this.

I have my SHSH blobs saved, but i've no idea how to use them. I also have no idea if i can downgrade to a version of iOS5. I know online articles suggest i can, but online articles also gave ways of solving the 3194 error & none of them worked.

So in the end, i'm happy that i can now actually USE the phone - make calls, send texts etc, but i'm not happy with what i've gained/lost.

I had the same issue, I read a tutorial where I flushed DNS, then I tried to upgrade and got Error 6.

I googled that error and it had to do with the firewall, I go to my settings and see the firewall was off, so I turned it on, then I went to go upgrade again and it worked.

As for a jailbreak, there is a "tethered" jailbreak available. But you can also downgrade from what I have read on The iPhone Dev team's website.

Edit: I just went to upgrade my iPad 2 because it didn't matter if it was jailbroken or not. But, I received the Error 6 message again, opened up my Firewall, since it was "On" so I just clicked on the lock to make changes (which I didn't), hit restore in iTunes and now my iPad 2 is on iOS 6. I'm assuming I need to run iTunes in Administration mode when I want to upgrade.

Google will release a Maps app either way eventually and it's not like there are no other navigation or maps apps in the App Store lol

Yes, if you saved your blobs, you can downgrade.

I have never done that before, so I'm probably the wrong person to ask how to do it and what to pay attention to, sorry. :/

Interesting, i was getting the same error while trying to upgrade from 5.1 to 5.11 so I could jb my ipad. I tried a range of things from tiny umbrella, to the hosts to different cables :p but did not try the reset. Not sure I still can do the 5.11 update as I believe the signing period has ended etc but your solution may be handy if I choose to go to 6 as I suspect it will give me grief still.

why would you expect your phone to be jailbroken after upgrading to iOS6? :s

Well a tethered jailbreak is available, just a matter of time before the untethered version is released.

    • Screamer is 50% off on Steam, making it £24.99 here in the UK: https://store.steampowered.com/app/2814990/Screamer/ You might remember the series from the mid 90s / early 2000s, this new game is also by Milestone who created the older games.
    • U.S. partially reverses Anthropic AI ban for Mythos but keeps Fable 5 off the market by Karthik Mudaliar Anthropic says that the U.S. government has finally allowed it to restore Claude Mythos 5. But of course, there's a catch. The rollout is again for a limited set of U.S. organizations that operate and defend critical infrastructure. The company announced this in a post on X (formerly Twitter). This does not mean that Anthropic's latest frontier models are back to normal availability. Fable 5, which was a tuned version of Mythos 5 for public release, remains unavailable. Anthropic said that it is still working with the government to expand Mythos 5 access and make Fable 5 available again, but there's no timeline. Reports from Bloomberg and Reuters say that this decision actually came through a letter from the U.S. Commerce Department. According to Reuters, this would allow more than 100 companies and institutions access to Mythos 5. Reuters also reported that Commerce Secretary Howard Lutnick’s letter removes the need for export licenses for approved companies’ non-US citizen employees, as well as Anthropic’s own non-US citizen employees, while restrictions remain for organizations outside the approved list. Anthropic isn't alone with this kind of controlled rollout. OpenAI's newest model family, GPT 5.6, was announced just yesterday, but isn't available for everyone yet. In its announcement, OpenAI also said that access to these models is initially limited to a select group of trusted partners and organizations, with broader access planned later this year. Both of these cases show that frontier AI launches are no longer just ordinary product releases and more like slow and vetted deployments shaped heavily by the U.S. government.

    • Microsoft Weekly: 5 years of Windows 11, more support for Windows 10, and expensive Xbox by Taras Buria This week's news recap is here, with Microsoft giving Windows 10 one more year of support, Windows 11 getting new taskbar settings in preview updates, Steam Machine prices, higher XBOX prices, and many more. Quick links: Windows 10 and 11 Windows Insider Program Updates are available Reviews are in Gaming news Great deals to check Windows 11 and Windows 10 Here, we talk about everything happening around Microsoft's latest operating system in the Stable channel and preview builds: new features, removed features, controversies, bugs, interesting findings, and more. And, of course, you may find a word or two about older versions. On June 24, 2026, Windows 11 turned five. The controversial operating system was released half a decade ago, and during these years, it received a fair share of criticism (such as poor Windows Search and its web results), which Microsoft is now actively addressing with regular preview updates that deliver missing, long-requested features. With Windows 12 nowhere to be seen on the horizon, it will be interesting to see if Windows 11 can stay on the market for as long as Windows 10 did. Speaking of Windows 10 and staying on the market, this week, Microsoft quietly prolonged the Extended Security Updates program for Windows 10, allowing users to get one more year of security updates if they do not want or cannot upgrade to Windows 11. Finally, Microsoft released this month's non-security update for Windows 11. KB5095093 arrived with a traditionally long list of new features, including point-in-time restore, new Windows Update settings, quieter Windows Widgets, new accessibility features, File Explorer updates and performance improvements, and more. Windows Insider Program Here is what Microsoft released for Windows Insiders this week: Builds Canary Channel Build 29617.1000 and build 28120.2374 These builds bring new accessibility features, new Windows Update controls, audio improvements, and more. Dev Channel Build 26300.8758 This build includes redesigned taskbar settings, File Explorer improvements, and more. Beta Channel Build 26220.8754 and build 28020.2366 This small update fixes the OneDrive bug in File Explorer, tweaks system sounds in dark mode, and more. Updates are available This section covers software, firmware, and other notable updates (released and coming soon) delivering new features, security fixes, improvements, patches, and more from Microsoft and third parties. If you use AI-powered browsing history search in Microsoft Edge, the company has bad news. A new update on the Microsoft 365 Roadmap revealed that Microsoft is discontinuing the feature. Despite using on-device models for natural search, some users found it creepy, claiming that Microsoft lacks trust in features like this. While the ability to find pages without using 100% precise words may sound cool, customers argued that it was nothing but another feature to bloat the browser with more AI. Good riddance? PowerToys received several updates this week. For one, Microsoft released version 0.100.1 with several improvements and bug fixes for the recently arrived version 0.100. A couple of days later, Microsoft dropped another update, this time fixing memory leaks in Command Palette Dock. In addition, the company is working on a new module that will make it easier to switch between windows within one application using the Alt + ` shortcut. The new module should make it to the stable release somewhere soon. Here are other updates and releases you may find interesting: New Ventoy update adds Windows 11's mandatory update support and more Microsoft updates Visual Studio Code with chat cost tracking and multi-agent chats Microsoft is building an AI datacenter that "uses less water than a fast food restaurant" Microsoft adds new AI study and teaching tools for free to Microsoft 365 Education Researchers claim Microsoft's quantum breakthrough is flawed by basic Python errors Microsoft is bringing a much-needed Recap app to Teams Microsoft's fast coding model, MAI-Code-1-Flash, comes to Copilot Business and Enterprise Here are the latest drivers and firmware updates released this week: AMD Radeon Software 26.6.2 with FSR 4.1 support for RDNA 3 graphics card. However, the driver contained a bug, which prevented installations on Windows 10 PCs. AMD fixed that with a quick hotfix update. Reviews are in Here is the hardware and software we reviewed this week This week, Steven Parker published several reviews. He shared his experience with the Creative Sound Blaster AE-X PCIe, a high-quality sound card with a headphone amp, low-latency communications, great build quality, and DSD256. However, it is on the pricier side of the spectrum, and it lacks EMI shielding. Check out the full review here. The second review is about the TerraMaster F4-425 Pro, an octa-core Intel NAS with a stand-out feature: built-in AI (OpenClaw). We also published a few Hands On reviews, which you can view below: We check out the SKG PS700 Neck Massager SKG Hand Massager with Heat OS500 hands on Hands-on with BOOX Tappy: cute little reading accessory Hands on with the ProtoArc EM25 affordable ergonomic mouse On the gaming side Learn about upcoming game releases, Xbox rumors, new hardware, software updates, freebies, deals, discounts, and more. If you plan to purchase a new Xbox, it's time to act now. This week, Microsoft announced yet another Xbox price increase. Starting August 1, 2026, all Xbox Series X|S models with 512 GB of storage will cost $100 more. As for the 1TB models, they are going up in price by a whopping $150. Finally, Microsoft is discontinuing the 2TB Xbox Series X. To make up for that, Microsoft announced a few programs to make its consoles more accessible. Those include BNPL, interest-free financing, pre-owned consoles, certified refurbished consoles, and more. Valve also shared some not-so-welcome news. The company has finally announced prices of the upcoming Steam Machine console, and if you plan to buy one, get ready to spend a whopping $1,049 on the 512GB configuration. The Steam Machine is now available for preorder, with shipments scheduled for June 29, 2026. Grand Theft Auto VI also received its official price tag. Rockstar Games announced that the long-anticipated game will launch at $79.99 for the base edition and $99.99 for the ultimate edition. The latter includes an exclusive collection of premium vehicles, weapons, apparel, and action threaded across all aspects of Jason and Lucia’s story." Those who preorder the game will get extra bonuses, including a Vintage Vice City Pack of cosmetic items as well as a free month of GTA+. NVIDIA announced new games for its GeForce NOW streaming service. Those include Dark Scrolls, SAND: Raiders of Sophie, Deer & Boy, EMPULSE, and more. Steam is running its annual Summer Sale, during which you can purchase plenty of various games with big discounts. It runs until July 9, so in case you missed it, you can still get some games at a lower price. Also, you can get two games for free in the Epic Games Store, plus more deals are available in this week's Weekend PC Game Deals issue.
