Wifi Grayed-Out: Troubleshooting & Fixes

27 02 2009

wifi-gray-outIf you are on trip, you may to switch on airplane mode to avoid any roaming charge. But sometimes, when I was in a cafe with free Wifi, I turned the Wifi on again. Everything works really fine until I was back home. When I tried to connect my iPhone to my home wireless network, it didn’t work. As I checked out the Wifi option in “Settings” screen, the Wifi option is just grayed out or disable by iPhone itself. Even I rebooted the iPhone, the wifi option still stayed in disable state.

This is not the first time I heard from my readers or other jailbreak iPhone users about this Wifi problem. But, I’m also have same experienced it on my iPhone. And here is the fix:

Reset The Network Setting

Just resetting iPhone’s network setting, the Wifi option comes back to normal. To reset the network settings, go to “Settings” -> General -> Reset -> Reset Network Settings.

I’m not quite sure if this is the universal solution to the Wifi Grayed-out issue. But this one works for my case

QuickPwn 2.2 is Here To Jailbreak iPhone 2.2 Firmware

23 11 2008

The iPhone Dev-Team have recently replied to Apple’s new iPhone 2.2 firmware with a new version of QuickPwn 2.2. Less than 24 hrs after Apple released the 2.2 firmware, the Dev Team have supplied a stable jailbreak and unlock for iPhone 2G users and jailbreak for iPod Touch 1G users.

There as a few points that you should notice here (Please Read Carefully)


For iPhone 3G

  • They suggest to use QuickPwn for iPhone 3G factory unlocked. You should use PwnageTool 2.2 to jailbreak your iPhone 3G without a factory-unlock, to prevent the baseband update and the future unlocks.
  • The new version of QuickPwn or PwnageTool will NOT unlock your iPhone 3G. iPhone Dev Team is still in process to develop a solution for unlock. And, if you’re using a locked version iPhone 3G and want to unlock in future, please do NOT use QuickPwn and do not use the official IPSW or iTunes update process.
  • In other words, if you’re using iPhone 3G, the only way to have a Safe Jailbreak is to use PwnageTool (Mac only). By using QuickPwn to jailbreak iPhone 3G, you’ll not be able to unlock your iPhone 3G in future, even iPhone Dev Team develops the solution.

For iPhone 2G

  • iPhone 2G (or 1st generation iPhone) user should have no problem with jailbreak & unlock firmware 2.2 using both QuickPwn / PwnageTool. As iPhone Dev Team mentioned, restore your iPhone 2G with iTunes, then run QuickPwn to do the magic.

For those using latest model of Macbook / Macbook Pro / Macbook Air

  • These latest models of Macbooks have an issue with DFU mode of iPhone. Please consider to perform jailbreak on other computers.

Before you update to 2.2 firmware you should aware a several statement from iPhone Dev-Team below. They state on the blog that:

  1. GOLDEN RULE: If you have a 3G iPhone and want potential soft unlock in the near future do NOT use QuickPwn, and do not use the official ipsw or the iTunes update process without using PwnageTool.
  2. Read item 1 again and again.
  3. At the bottom of this post are the bittorrent files for the latest versions of PwnageTool and QuickPwn.
  4. These are suitable for the recent 2.2 release.
  5. Please read all parts of this post before downloading and using these tools.
  6. The ‘late 2008’ MacBook/air/pro line of computers have an issue with DFU mode.  While it’s possible to go from Pwned 2.1 -> Pwned 2.2 (using PwnageTool), you can’t yet go from stock to pwned.  If in any doubt use a different machine.
  7. Choosing the correct tool is crucial. Be warned!

NOTE: ‘Simple Mode’ in PwnageTool currently only works for the iPod Touch. To use PwnageTool for iPhones you will need to use ‘Expert mode’. This is a workaround while we make an update and fix this issue. In order to do this you will need to navigate to the ‘General’ window and change two things: Deselect ‘activate’ ONLY if you are normally able to activate through iTunes (but if you wish to ‘hacktivate’ the iPhone using PwnageTool then leave it selected).  You will also need to change the partition size to about 1000MB (type in the value or use the slider).

‘Hactivate’ means to activate the iPhone yourself without Apple. This is used if you live outside an officially supported region and cannot activate the phone using iTunes.

Baseband 101

The ‘baseband’ is the generic name given to the internal components of the iPhone that handle the phone calls and Internet access. This ‘baseband’ is a tiny and unique independent computer system that runs inside your iPhone, it is separate to the main system that handles the applications (such as email and google maps) and it talks to the main part of the phone over an internal communications network. Think of it like a cable modem or other peripheral that is attached to your home PC that needs occasional updates. When a software update is released and presented to you within iTunes the baseband is sometimes updated (to fix bugs or add new features). The 2.2 update for the iPhone 3G contains such an update, so running the vanilla updater straight away with iTunes will reprogram and update the baseband. This could be bad for certain people, depending on your ultimate aim.

SIM Free/SP Unlocked/Factory Unlocked iPhone 3G

This applies if you bought your iPhone 3G for $$$$$$$. This model of iPhone 3G doesn’t have an Service Provider lock (aka factory unlocked) and you are able to put any SIM card into the phone and get service. Your phone is already unlocked so you do not need to worry about baseband updates, simply upgrade to 2.2 using iTunes and then use QuickPwn to Pwn and Jailbreak. This will add Cydia and Installer too.

Locked iPhone 3G – Preserve Baseband

This applies if you have a locked iPhone 3G and you wish to update to 2.2 but preserve the iPhone’s current baseband software. Preserving the baseband will give you the maximum chance for any upcoming software unlock. To upgrade your phone to 2.2 and preserve the state of the baseband you need to create a custom .ipsw with PwnageTool. This custom .ipsw will not contain the baseband update but of course will still allow all the cool new stuff from 2.2.

There are plenty of tutorials about this process on the web, but PwnageTool contains intuitive graphics and easy to follow prompts that should have you up and running in no time at all.

Locked iPhone 3G

If you are using your iPhone with one carrier and have no interest in the possibility of an iPhone 3G unlock in the near future then just restore or upgrade to 2.2 using iTunes and use QuickPwn to Jailbreak and add Cydia and Installer.

iPhone 2G (1st Generation)

Restore your iPhone 2G with iTunes then run QuickPwn to do the magic, ‘nuff said.

iPod Touch 1G (Original iPod Touch)

Update to 2.2 with iTunes and run QuickPwn.

iPod Touch 2G (New iPod Touch)

Sorry, no support at this time.

Warning: Do Not Update to 2.2 Firmware

23 11 2008

This is a reminder that those interested in a software unlock should not update to the 2.2 firmware until instructions are made available. Quoted from iPhone Dev-Team, the developers of QuickPwn and PwnageTool mentioned you better hold off the upgrade.

So, as anticipated our friends the misfits have recently released the long awaited 2.2 update. We can confirm that this update SHOULD NOT be applied using iTunes if you want the chance of a soft-unlock in the near future.

Also,

If you apply this update and you previously relied on PwnageTool or QuickPwn to activate your phone, it may become temporarily deactivated and unusable (until we release the new version of PwnageTool or QuickPwn).

The existing version of QuickPwn and PwnageTool was designed for jailbreak and unlock firmware 2.1. You should expect the next version of the tools can jailbreak firmware 2.2 and will be released very soon as the team noted,

We believe that our Pwnage technique (and therefore the Jailbreak) isn’t affected, but PwnageTool and QuickPwn do not support this release as yet, so DO NOT install 2.2 using iTunes as you will lose your jailbreak.

and

PwnageTool and QuickPwn updates will be released as soon as possible that will allow a safe update path to 2.2.

So, please hold off the upgrade and stay tuned. Considering that the iPhone Dev-Team is one step closer to finishing the unlock, I would strongly recommend you wait until i post the proper upgrade tutorial.
