Just flash and check "The Evolver". We have tons of features combined together from different ROMs.

What are our features?

Spoiler content hidden.

* VoWiFi calls working only if mobile signal is available.

* Some users found the device unresponsive after long periods of inactivity needing to force rebooot the device. Not happening to everybody and no often at all.

PLEASE DO NOT FLASH GAPPS, THEY ARE ALREADY INCLUDED

First Time Install / Clean Flash​

1. Download the proper ROM ZIP for your device

2. Reboot to recovery ( these with decryption support are recommended)

3. Install the latest firmware if not already installed

4. Format Data if you come from retrofit, EROFS or A12 in any case, and any other situation if your Data is encrypted

5. Wipe Data,Cache and Dalvik cache

6. Flash the ROM

7. Install Magisk if you want (v25.2 or newer are recommended)

8. Install the ForcedEncryption disabler if you want to keep your Data unencrypted

9. Reboot to System and #KeepEvolving

Update / Dirty Flash from the system's updater app​

You can install OTA update from the system's updater app if your Data is encrypted, you only need the current EvolutionX recovery for Cepheus or a compatible recovery like the ones recommended above. If you acomplish these requirements, go to Settings/System/Updates, check for updates, download it if available and apply it, the system will do the rest rebooting in recovery, installing the update and rebooting the system.

It's not recommended to update using the system's updater app if you disabled the forced encryption previously since the process described above doesn't include the encryption disabler so your device wouldn't boot the system after installing the update and you would be stuck in the recovery being forced to Format Data and re-install the ROM.​

Update / Dirty Flash manually from the custom recovery​

1. Download the proper ROM ZIP for your device

2. Reboot to recovery (these with decryption support are recommended)

3. Wipe Cache and Dalvik Cache

4.Flash the ROM

5. Install the ForcedEncryption disabler if your data was non encrypted before

6. Install Magisk if you want (v25.2 or newer are recommended)

7. Reboot to System and #KeepEvolving
