Guide to Install Android 5.0 Lollipop on Xiaomi Mi 3W [AOSP ROM by Ivan]

The wait is finally over for Xiaomi Mi 3 users (almost) as ‘Ivan’, the popular developer at Xiaomi has released a working Android 5.0 AOSP ROM for Mi 3. The ROM is based on the latest Android 5.0 Lollipop OS but it is not a final version and contains some bugs. The Lollipop ROM with build version 4.12.9 is available only for Mi 3W (WCDMA variant). The ROM by Ivan comes with minimal apps, thus offering users a Nexus like pure Android experience on Mi 3. It supports English language and seems pretty stable. As there are no Google apps included, you need to flash the appropriate Gapps file separately. Interested users can follow the below stated step-by-step procedure to flash Android 5.0 Lollipop on Mi 3W. The official Android 5.0 by Xiaomi will reportedly be released by Q1, 2015. So, either wait or better taste it now!

• Reboot into CWM Recovery (Go to Tools > Updater > press Menu key and select ‘Reboot to Recovery mode’)

UPDATE: There is an easy workaround to fix the reboot issue in Ivan’s Lollipop ROM for Mi 3. To do so, download and install the Wake Lock – PowerManager app from Google Play. Open the app and enable the “Partial_Wake_Lock” option. Then go to its ‘Options’ and enable the ‘Autostart on boot’ option. We’ve tried this and can assure that your Mi 3 won’t reboot automatically. You can check the phone uptime from About phone > Status > Up time.
