How to find out if iPhone 3GS is an old bootrom or new bootrom

Apple iPhone 3GS models has either old bootrom or new bootrom. What is the difference between the two? Well, jailbreaking community found bootrom exploit for iPhone 3GS back in 2009. Bootrom exploit actually meant that hardware exploit for iPhone 3GS has been discovered and it can be jailbroken (untethered) on any new firmware that Apple might release in the future. To fix this, Apple started to produce new iPhone 3GS’s which had ‘new bootrom’ or ‘fixed bootrom’ after 9th of September, 2009.

So if your iPhone 3GS is an old bootrom, you can always jailbreak (untethered it) on any new firmware version. And if it has new bootrom, you still be able to jailbreak it but you won’t get untethered jailbreak until jailbreak communities find exploit for that specific firmware.

In this tutorial, you will learn how you can find if your iPhone 3GS has old or new bootrom.

Step 3: At the bottom of Redsn0w, see if it reads old BR. If it does, then your iPhone 3GS has old bootrom. Otherwise it has new bootrom.

How to Enable Battery Percentage in iPod Touch 5, iPod Touch 4

Battery percentage is enabled in iPhones and iPads by default but in case of iPod Touch, there is no option there in settings to enable battery percentage. With a little trick, you can enable it on your iPod Touch 4G, or iPod Touch 5G. The only thing you need is a jailbroken iPod.

You can jailbreak your iPod Touch 5 using Evasi0n jailbreak tool. Follow the guide posted here. If your iPod Touch 4 is running iOS 6, then you can use Evasi0n tool to jailbreak it. And if you are running iOS 5, search Google for Absinthe jailbreak and you will find out how to jailbreak it.

I assume that your iPod Touch is jailbroken by now. Go to Cydia, search for SBSettings and install it.

Now open SbSettings app found on one of your page of iPod Touch. Scroll down until you see System Options. Tap on that and finally enable Numeric Battery option.

Today I downloaded Hitman 5 Absolution from Sorry about not buying the game and downloading it illegely. I had already finished it on my Xbox and just wanted to give it a shot on my PC. Anyways, the game was crashing right after selecting difficulty level. Something like “Hitman 5 Absolution has stopped working” on my Windows 8 – 64 bit.

Step 3. After a short while, a pop-up window will appear stating that Steam is updating. Click Cancel.

Step 3.1. If steam doesn’t autmatically start after installation, manually run steam.exe from your desktop.

That’s it. Now run Hitman 5 and you won’t face up with crashing after selecting difficulty.
