Apple rolled out a new OS upgrade, iOS 10.3.2 a couple of days ago and the latest update brings about minor changes to the operating system. The update is available for iPhone, iPod Touch and iPad. Just like always, this upgrade breaks through jailbroken devices. The upgrade is compatible with iPhone 5 and above, iPod Touch 6 Gen and above, and iPad 4 and above. To manually download the upgrade, go to Settings > General > Software Update.

What exactly does this upgrade do? The latest upgrade brings about changes in security of the device. It secures many of the flaws and though minor, is actually pretty big in a quiet way. However, like many Apple upgrades, this one too is not without its flaws. The new update has been bashed on social media for bringing up what seems to be an old issue reportedly resolved by Apple. Looking at both the parameters, the question arises – should you upgrade?

The Good

iOS 10.3.2 brings some much needed changes to the security of the device. The description on the new update does not vary from the bigger 10.3.1 update rolled out earlier, iOS 10.3.2 includes bug fixes and improves the security of your iPhone or iPad.” As per the listing on Apple’s support page, iOS 10.3.2 resolves 23 different security flaws in applications and the device.

Apple resolves two major security flaws in the device kernel, letting applications execute arbitrary code with kernel privileges or read restricted memory; over 20 WebKit-related flaws, most serious of them found in iBooks. The flaws led to processing maliciously crafted web content may lead to universal cross site scripting and arbitrary code execution. Multiple SQLite flaws are also resolved. Apple has updated its Safari browser which will now deny user access to a suspicious or established malicious page.

Apple has long since neglected the iPod and the device is clearly nearing the end of its life with no new releases or any patches. However, iOS 10.3.2 resolves issues faced by iPod users, making it an important update. Overall, the latest update brings about some much needed security improvements which could traditionally negatively affect the device and compromise security.

The Bad

Though the upgrade does bring some much needed changes to the device security, one of the major issues users are facing is the battery. Many users are complaining of low battery performance post the iOS 10.3.2 upgrade. Surprisingly, excessive battery discharge has been reported even while it is switched off. Unplugging from the charger causes the battery to drop by nearly 20 percent almost instantaneously. Infamously called the ‘30% Battery Bug’, the issue Apple reportedly resolved in iOS 10.2.1 is back.

Apart from battery woes, many users are also complaining of TouchID errors and getting locked out of the device, sudden app crashes, missing photos and random update failure. ALSO READ: Apple iPhone 8 final look leaked, the smartphone stays true to rumors

How-to downgrade to an older version

Clearly, the positives outweigh the negatives in this update. Though the security updates matter much more than battery issues, if as a user battery matters the most to you, we would suggest waiting a bit till Apple releases a patch for the issues. However, if you’ve already downloaded the latest upgrade and wish to now downgrade, how do you do that? Follow the instructions below:

1. Backup all data

You need to first back-up all your data and ensure it is saved so there is no data loss in case of an unsuccessful attempt. Backup to iTunes and iCloud and Archive the Backup. However, files backed up in iOS 10 won’t be available for iOS 9.

2. Locate the .ipsw file

You need to find the file for the older version you wish to downgrade to. If you wish to go back to iOS 10.3.1, locate it on your hard drive, in the iPhone Software Updates folder. Simply follow youruserfolder/Library/iTunes/ to locate it. You can even download it from an external site.

3. Open the .ipsw file

Once you download the file, connect your device to your Mac or PC and open iTunes. Disable the ‘Find My’ feature on your device. Under the iTunes interface, click on your device and select Summary. Now hold down the Alt/Option/Shift (key, and click the Restore button. Navigate to iOS .ipsw file and click Open. iTunes will begin installation of the older version.

4. Recovery Mode

If the above method fails, try upgrading in Recovery Mode. Power off your device and connect it to the Mac/PC. While connecting, hold down the Home button and iTunes will activate Recovery Mode. Press and hold the Option/Alt key, choose restore and open the .ipsw file.
