Owners of Xiaomi Mi3 are in for some great news, as the industrious CyanogenMod team has unleashed the latest custom ROM for the flagship smartphone via Android 5.0 Lollipop based CyanogenMod 12 ROM.
With Xiaomi refusing to publish the source code for their kernels, it becomes impossible to create a custom kernel for third-party Android developers.
However, a group of developers from CancroCM Team comprising XDA senior members kD, audahadi, kairi_zeroblade, XDA Forum member david_korbu and XDA Recognised Contributor jack_eagle have successfully created a functional and highly stable build of CyanogenMod 12 for the smartphone.
Despite the effort of the CancroCM Team, the ROM is not free from a handful of minor bugs with Bluetooth connectivity, NFC, camcorder and USB-OTG.
Except for these bugs, the rest of the features are reportedly working fine with the new CyanogenMod 12 ROM for Xiaomi Mi3.
Interested users can go ahead and install this ROM manually on the Mi3 via CWM recovery, using the step-by-step guide provided below.
IBTimes UK reminds readers that it will not be held liable for any damage to device during or after the ROM installation. Users are advised to proceed at their own risk.
