Fix iPhone 3GS Endless Reboot or Sudden Shut Down After Replacing New Battery

Got your iPhone 3GS battery replaced and now it keeps booting every few minutes or so? Try this fix.

This issue seems to be caused by the battery or how the iOS handles power management of the iPhone. Sometimes after a battery is replaced, when the power percentage drops to 30~50% the iPhone will turn off. After trying to turn it back on again it goes into an endless cycle of showing the Low-Battery screen. It then attempts to start with the Apple logo, then restarting all over again in a minute or two.
The folks at reported that:
This could be a mismatch between the presumed or old battery charge curve and the new battery is likely. Mostly the iOS installed thinks that the battery still has 30~50% of power left when in fact it empty, a lot of this is because lithium cells have an exceptionally flat discharge curve and thus estimating the energy left is not always practical without keeping track of the mAh consumed.

Now here’s what you can try:

1. Put the iPhone 3GS into DFU mode (black screen)

a. Hold down the power button for 4 seconds
b. Hold down the home button for 10 seconds
c. Release the power button
d. Wait 15 seconds
e. Release the home button

2. Charge for 30 minutes.

3. Exit from DFU mode.

a. Press the home + power button for 15 seconds
b. Release both buttons
c. Press the home button for 3 seconds

Your iPhone should now be booting into normal mode and you should be able to continue charging normally once more.


Temporary Fix for iPhone 5 Weak WiFi Signal or Connection Issue on iOS 6.x

The iPhone 5 is great but we’re constantly receiving emails from customers on how to fix their WiFi issues. Here’s a temporary fix while waiting for a permanent fix from Apple.

This isn’t the first time an iOS device has had issues connecting to routers and hotspots.

This solution may not work for everyone and definitely not a permanent fix. However, many have reported that their WiFi signal has significantly improved after doing this.

The fix is accomplished simply by changing the protocol used by your router over from WPA/WPA2 to WEP. Newer routers are quite straight forward to configure. When in doubt, Google for your router’s model number and a bunch of tutorials should come up to guide you on how to change the settings.

Essentially, all you need to do is go to the Wireless and Security options on the router, and select WEP instead of WPA.

Once again, this may not fix everyone’s issue but worth trying. Now let’s wait for more software updates from Apple.

Apple Released iOS 6.1.1 for iPhone 4S with Baseband Updated to 3.4.02 (Jailbreak Safe)

Two weeks after the release of iOS 6.1, Apple rolled out another update specifically for the iPhone 4S.

This update is really critical because according to Apple, it is supposed to address an “issue that could impact cellular performance and reliability”.

The “performance and reliability issues” are related to sending text messages, connecting to your cellular network, and also something related to Microsoft Exchange.

European carriers in particular Vodafone UK sent out warning to its customers not to update their iPhone 4S without waiting for this patch. Hopefully, this patch will help sort out affected customers.

Due to the critical nature of this 23MB update, Apple probably didn’t spend any time patching the untethered jailbreak exploits found in iOS 6.x, which means it’s safe for iPhone 4S users to continue updating to iOS 6.1.1 and jailbreak it with evasi0n 1.3.

Meanwhile, the baseband is now updated to 3.4.02 and as usual, there’s won’t be any ultrasn0w or any “free” unlock available for this baseband. An official unlock is by far the best solution for now.

Here’s a direct download iOS 6.1.1 10B145 for iPhone 4S hosted on Apple’s server.


Fix for iPhone 4 Baseband 1.59.00 No Service Issue with Ultrasn0w 1.2.8 on iOS 6.1

If you have an iPhone 4 with baseband 1.59.00, you will encounter a major compatibility issue with ultrasn0w 1.2.8 and iOS 6.1.

You will notice the following symptoms:

  • It cycles between “no service” and one bar signal with 3G.
  • Every 20 seconds it pops up one bar for your network and then returns No service.

Unfortunately, there’s no fix for now. Even the ultrasn0w fixer won’t do your iPhone 4 any good.


See the comments section below for possible fix.

Your best option for now is to downgrade your iPhone 4 back to iOS 5.1.1, assuming that you have the SHSH for it, but most of you should have it saved on Cydia/Saurik’s server already.

Of course, the best solution is to get your iPhone officially unlocked so you won’t need to deal with this type of problem in the future.

Meanwhile, let’s wait for a a fix from the Dev Team.
