ROM developer community, CyanogenMod, has released CM12.1 snapshot [stable] version for YU Yuphoria.
The new CM12.1 is different compared to the official Cyanogen OS 12.1 series. While the former has been created and tested by independent developers, the latter has been developed by dedicated software engineers of the company.
YU had claimed that Cyanogen OS 12.1 for Yuphoria entered final testing phase back in June, but it is yet to be made available for the device.
Tech-savvy YU device owners who are tired of waiting for the official version can try out the new CM12.1 version.
It is around 367MB in size and brings IMAP idle support, SDK v1 release and numerous bug fixes, including those to the Stagefright security loophole.
Prerequisites (Things to remember before installing the Custom ROM):
- Make sure the device is rooted before going ahead with custom ROM installation.
- The new CyanogenMod CM12.1 [official] Android 5.1 Lollipop custom ROM - has to be installed on the YU Yuphoria aka lettuce model only ; if tried on other devices, it might get bricked [To check your device model: Go to Settings >> About phone >> model number]
- Users are advised to pay close attention to the CM release version and check whether the version of their third party installs (kernels, mods, gapps, etc) are compatible with the custom ROM.
