1. Download CM12.0 for S3 Mini [HERE] or [HERE] and Google Apps Package [HERE] and copy both the zip files to the device’s SD card storage.
Note: Download recovery version of the ROM
2. Turn off Galaxy S3 Mini and reboot it into recovery mode. To do so, press and hold Volume Up, Home, and Power button few seconds.
Note: This guide is based on CWM recovery
3. From recovery, perform a factory reset (choose “wipe data/factory reset”) and wipe cache partition (choose “Wipe Cache Partition”)

2. If above procedure isn’t helped you, remove battery from your phone and then re-insert it and follow the above installation instructions again.

The ROM isn’t fully stable. I had mentioned it in the guide.
whether this rom stable ?
Ensure your S3 is i8190, i8190L or i8190N. I suggest you to download the rom (recovery version) and flash it again. Odin version of the same ROM is also available. Download and try to flash via Odin.
Hi, I downloaded the latest version of the rom, and tried to install it with this guide, but I got a message saying Warning: no file_contextsdetected at ext4 filesystem dev block 22. I then got a message saying it detected an ext4 filesystem at the same location. After that, the recovery froze and I had to pop my battery out and restore my backup. I followed the guide exactly. (I may have cleared the cache before factory resetting the phone. Not sure.) This has happened every time I try to flash the zip. Is there any way I can fix this?
My phone is bootloop,when i install cm 12 is aborted ‘no file context detected’ can you help me?
