Problem : No GPS signal, they are almost dead. You won’t find even a single tower connectivity in Navigation applications like Sygic.
Here is a working solution to fix it to great extent.
Solution: You need to install Pushfix 3.1.3 using “Cydia”.
Go to Cydia -> Sources -> Edit –> Add http://fishbone.ge
Search Pushfix and install it. (P.S. After installing PushFix all wireless network passwords, email passwords are deleted, you just have to update them again.)
Please Note the wireless(Wi-Fi) needs to be always active, it does not matter whether it is Connected or not. It will not point your accurate position there may be an error up to 10 meters. Also it will not show full signal bars in Navigation Applications. The pointer will move as you go but may not display your speed.
Well this is like heaven instead of having a dead GPS. 🙂
Ok, so you might have restored your iphone 3gs using 4.3.3 ofw(official firmware) or cfw(custom firmware) using sn0wbreeze and also it might went into DFU mode loop. NOT recovery. All there could be a black screen.
I had also faced the problem problem with my 3GS. And I fixed it using redsnow beta 0.9.10b3.
Here is the stepwise description of the fix:
- Download Redsnow 0.9.10 beta3
- Download offical 3GS firmware 4.3.3 for 3GS
- Run redsnow beta 0.9.10b3 and click on “Extras” command button
- Put your device on Pwned DFU by clicking on “Pwned DFU” command button
- Create custom firmware preventing baseband update
This will create a custom firmware file that will prevent baseband upgrade in the same folder with “NO_BB” prefix in the file name.
- Start TSS server using Tiny Umbrella and restore the newly created custom firmware using iTunes.
That’s all! Now Jailbreak the device using the same version of Red Snow.
Follow the printed instructions. And here you go with your device jailbreaked. 🙂 Now unlock it using ultrasn0w using this guide http://iguidespot.blogspot.com/2012/01/how-to-unlock-iphone-3gs-firmware-433.html.
The iDevice in your hand (iPhone 2G, 3G, iPod Touch) is factory fitted with ARM Cortex processor having more Hz speed than you think. But that has been underclocked to provide effective Battery life.
That is clear that the processors fitted in the device are not fully harnessed, but it is possible with overclocking process. But your device should be Jailbroken tp process that method. The actual processing capabilities of iDevices are :
iPhone 2G/3G = 600 MHz (underclocked to 412 MHz)
iPhone 3GS = 833 MHz (underclocked to 600 MHz)
Steps to Overclock the CPU (iPhone 2G, iPhone 3G, iPhone 3GS, iPod Touch)
- Using a SSH tool like Filezilla or iPhone Folders navigate to
- Rename file “com.apple.SystemPowerProfileDefault.plist” to “SystemPowerProfileDefaultbak.plist” or whatever different.
- Reboot, and your iPhone/iPod Touch would Run on native Processor clocks.
Note: Increasing the clock speed would degrade the CPU’s lifespan by several minutes. However, since the device is not designed to handle the heat generated at higher clocks, we recommend you to terminate apps if device appears to overheat.
Easy steps to Update Apple’s iPhone 3.0 software
Firstly, before anything else, make sure that the battery of the iPhone is fully charged, and also if you are using a laptop, make sure it is plugged into the power outlet or be ready with some alternate power source.
If you must use the battery on your laptop, make sure you have enough power to last through downloading a 200MB file, installing, and updating your phone. You don’t want your laptop to die in the middle of your iPhone update, it might damage the phone.
Secondly, end users need to download and install iTunes 8 . iTunes 8 lets the phone communicates with the computer so it can be updated.
Next prepare to connect the iPhone to the computer with iTunes 8 software installed. Wait for sometimes until iTunes opens. When iTunes opens, select your iPhone under Devices in the Source List on the left and then navigate to ‘iPhone Summary pane’ and click the buttons for ‘Check Update’.
In no time a message will appear click ‘Download and Install’ wait until the updates has finished and there you have it the new iPhone OS 3.0 software updates.
One of the best things about the iPhone is Apple’s openness to accepting new apps from independent developers. But getting your app on the iPhone is competitive, so how is your app supposed to stand out from the crowd? By checking out these websites and forums, you can keep up with all the news, issues and opinions about the iPhone, so that you’re better prepared to design something that Apple decides it just needs to have.
