About this ROM & Further development.

Actually this ROM is made for my son for his device just for fun & learning purpose for him. At the moment there is no further plan to develop or update this ROM. I thought to share it here if any other users wants to use it.
So please don't expect any further update and use this as it is.
Thanks.

This ROM here provided for end users. Not allowed to modify/allowed to copy any modified part.
Best way you can make your own from stock firmware.

 

[esirad]

Tnx , awsome rom

You are too restrictive. Imagine Samsung didn't allow you to unlock the bootloader, or Samsung didn't give the source code of the kernel(I know this ROM doesn't depend on a custom built kernel but still, restrictions...)

I know you put some effort in to making the ROM but its not like you own the components inside the ROM.

Maybe you could atleast share some insight about making custom ROMS(the tools you use for example), links, tutotrials, I am interested.

Aod not working

Aod not working

Check your settings,(click on Text of QS panel aod toggle) if it is set to show as schedule then set schedule as per need or set as always
Working fine here as it should.

That is not actual size of rom (contents) but it is size of system. After flashing rom still you will have enough space on system. Rom already have debloated many apps.

 

[esirad]

I re flashed , its work now
Rom is smooth

Hello everybody.

Somehow this rather new thread drew an unproportionate amount of off-topic posts and spam. Keep things respectful and on topic.

Thread cleaned.

Sorry I don't know about cross flashing for this device as I am not using this device.
It is based on Indian J730G firmware.

Tested Jio volte and working perfectly.

I already tried your ROM for almost 2 weeks now and it's pretty stable but there is one thing that keep bothering me when I open the camera, smart view and gallery app the "nearby services keep stoping" dialog always popup. Is there any solution to this? Did anyone has the same problem?
