The Yalu Jailbreak was the First Jailbreak in iOS 10 which is still used by many People by Now. The Jailbroken version was 10.2 which is Super Stable, Yalu called it the Mach_Portal and is based on Project Zero Exploits powered by Google. Apple immediately Patched it, now the users on iOS 10.2.1 or above can not Downgrade to iOS 10.2.
People Still on iOS 10.2 can install Yalu and enjoy the Cool Jailbreak except for iPhone 7 Users and iPhone 5 Users (Since iPhone 5 runs on 32-bit). The iPhone 7 and 7 Plus Users can only Jailbreak if they are Running on iOS 10.1.1 which is also Unsigned by Apple.
Predictions for the ios 10.2.1 or 10.3 jailbreak
A person named Luca Todesco has been a Skillful person and is Genius in Hacking and Jailbreaking but Jailbreaking the iOS 10.2.1 or above is a Great Challenge as it has completely Different File System Now called APFS. Apple hates Jailbreak and they will do anything to Prevent it. Todesco has also said that he will soon stop his Work maybe after his next Project.
Without any sign of Jailbreaks, for now, you could not do anything Right Now. Maybe Pangu this time can do something Miracle (Maybe) but if you are Running on iOS 10.2 or below, we highly Recommend you to Jailbreak Right Now.
SHOULD YOU UPGRADE TO IOS 10.3?
The iOS 10.3 is still not out, anyways you could install the iOS 10.3 (Beta 6) Easily on your Device if you want to but will it be the Same mistake as upgrading to iOS 10.2.1 from 10.2?
The iOS 10.2.1 and iOS 10.3 seem to be having almost same File Type and if the Experts even Jailbreak any new Version of iOS, that should definitely be iOS 10.3 because jailbreaking the iOS 10.2.1 doesn’t make any sense, as everyone could Upgrade to iOS 10.3 Right Now.
So it’s up to you to Decide whether to Upgrade to iOS 10.3 or not but I would suggest you stay on iOS 10.2.1 because maybe the Experts are working on iOS 10.2.1 Jailbreak.
IF YOU ARE RUNNING ON iOS 10.2 OR BELOW, HERE’S A GUIDE ON JAILBREAKING IT
