You can port your one with this method

Did you modifed with my method, and paste my kernel(F90M) instead of yours ? 

[Huy Minh Bui]

If you have a Linux Distro installed in your PC then you should compile it rather than port it. That's my advice

Also, I remembered that I compiled PhilZ for F90m :

This phone was not mine, asap from this I haven my Laptop to compile recovery.

Only have PC that loaded with less power.

but can you tell me why GerdaOS Compiled from source aren't booting? 

I compiled with WSL or should i try with Linux as 1GB RAM ?

I wasn't aware about you I will change recovery credits soon and will direct toward you.

[Veera B]

Never mind, have sent that message from jio phone. Typing on jio phone is much challenging, as you know.

Btw, what are steps to be followed to prepare custom recovery and OS?

Do we have any document which lists the features of Gerda os is over stock?

Is there any improvements done to browser?

[Sachin Borkar]

After my port I thinks Development will start unofficially.

 We do't have any document yet, atleast I didn't read yet.

The browser have updated some features as it was in GerdaOS in Nokia 8110.

VoLTE Fixed Now :-)

[Rebellion Duke]

[Sachin Borkar]

We can use our previous plans, without detection.

and MyJio app needs to be ported if you want.

Someone will port it soon.
