WARNING! Although I find a way to install this on our beloved SHV-E370K, this ROM is official for the GT-I9190 and GT-I9195 variant only, and therefore may not have support from CM team!
Your warranty is now void. I am not responsible for bricked devices, dead SD cards, or lose your data. PLEASE READ THIS THREAD COMPLETELY AND BACKUP YOUR NAND BEFORE DO ANYTHING.
Note 1: If you do not know how to use ODIN, flash a recovery, and/or using CMW recovery, please have a research before trying anything.
Note 2: This method do not require root.
Note 3: ROOT access is implemented in CM12 rom, so do not ask me how to root.
Note 4: 3G working fine. LTE are not tested (although it suppose so). Network operators in my country do not support LTE yet, so I can not guaranty it is work.
Note 5: Tested on CM-12-20150123 and 20150124.
CM-12.0 Android Lollipop 5.0.2 Install Guide.
1. Make sure you have latest ORIGINAL ROM (build E370KKTU2BNK5) installed on your device, or at least the baseband E370KKTU2BNK5. You can check this by go to Settings -> About phone -> Baseband version. This is to ensure all network connections are functional.
2. Download and install CMW recovery (attachment).
3. Download CM-12.0: https://download.cyanogenmod.org/?device=serranoltexx. And GAPPS for Android 5.0: http://forum.xda-developers.com/para...-apps-t2943900. Put those file into your SD card (internal memory also work).
4. BACKUP your DATA (SMS, picture, contact, ...) before taking next step.
5. Reboot into recovery by completely turn off your phone. Press VOL + and HOME and POWER button at a sametime for 2 - 3 seconds.
Backup your phone by go to "Backup and restore -> Backup to SDcard". You will need this backup later if you decide to go back to your previous ROM and data.
Go to "Install from sdcard" and install ROM file first, then GAPPS file.
Wipe Data, Cache and Davik cache.
Reboot your system.
6. Wait till boot complete and enjoy CM12 on your little SHV-E370K. Restore your data if needed.
Warning: Do not restore backup data of system apps!
If you restore a bad backup with cached settings in telephony.db in data/data/com.*.*.telephony it can break MMS.
It seems that restoring backups can also break Calendar sync.
Upgrades
Upgrades from previous versions of CM-12.0 are the same process as install, except you do not need to wipe anything. Contrary to popular belief, you do not need to even wipe cache and dalvik-cache when upgrading between CM-12.0 versions. You only need to wipe if you are doing a major upgrade, switching to a different ROM entirely, or attempting to fix bugs caused by bad backups or corrupt app data.
