Limitation: Free Apple IDs only keep sideloaded apps active for 7 days. You must refresh the app via your computer every week, or the app will crash on launch.
Success Rate: Medium. Only works if your Apple ID history includes that specific version.
The iPhone 6 only has 1GB of RAM. Modern YouTube is a RAM hog. Surprisingly, this legacy version is much friendlier to the hardware. I didn't experience the crashing or freezing that often plagues other updated apps on older firmware. The phone ran cool, and battery drain was manageable.
If you never downloaded YouTube 1257 before, you can manually sideload the .ipa file (iOS app package). This requires a computer.
For iPhone 5s, 6, 6s, 7, SE (1st gen), or iPad Air on iOS 12-14, jailbreaking is the most reliable way to permanently install YouTube 1257 without expiration. install youtube ios 1257

Installing apps on older iPhones running iOS 12.5.7 can be more complicated than on modern devices because many current App Store versions require newer iOS releases. YouTube’s current app may not support iOS 12.5.7, but there are practical paths to get YouTube functionality on such devices. This essay explains why installation can be difficult, outlines several step-by-step options (official and workaround), evaluates their trade-offs, and concludes with a recommendation.
Why iOS version matters
Option 1 — Official App Store with “last compatible version” Limitation: Free Apple IDs only keep sideloaded apps
Option 2 — Use YouTube in the browser (recommended when the app won’t install)
Option 3 — Install via a family member’s or another Apple ID that previously downloaded YouTube
Option 4 — Use an older IPA via third-party tools (not recommended)
Option 5 — Jailbreaking (not recommended) Success Rate: Medium

Recommended path
Conclusion While iOS 12.5.7 limits direct installation of modern YouTube app builds, you can still access YouTube reliably via the mobile site or, in some cases, obtain a last compatible App Store version tied to an Apple ID’s download history. These options balance safety, usability, and risk: the mobile web is the simplest and safest; the “last compatible version” from the App Store can restore the native app experience if available; sideloading or jailbreaking poses significant risks and is not recommended.
