Redmi 3S development == Redmi 4 prada too? (2/16 version)

[Kizoky]

I'm still waiting for my phone to be arrived, but unfortunately they told me Xiaomi no longer distribute 3S, so instead they gave me the idea to keep a Redmi 4.

My question is, do Redmi 3S recovery/kernel, custom ROMs work on Redmi 4?
The only difference is the camera, Wi-Fi, and Bluetooth everything is the same as Redmi 3S

Could you explain why it wouldn't work?
Redmi 3S and Redmi 4 both has the same chipset aswell as GPU

Maybe the current 3S development scene will be useful as an initial base for future development with the redmi 4, but we don't know if the rest of the hardware will be the same (touch input, RIL, microphone, partition table, etc etc.). If the hardware is different, devs will have to dig another models or brand source drivers, make new binaries, blah blah.

So if you're asking if a ROM built for Redmi 3S will work on Redmi 4, the answer is NO, and trying it is firmly discouraged.
If you're asking if 3S ROMs will share code or serve as base for Redmi 4 ROMs, the answer could be a YES, but a real dev should answer this after trying.

I compared every file, and It seems prada indeed is the same as land's 16GB version
There are some minor differences, but It seems they are really the same.

If you check this: https://github.com/Kizoky/android_device_xiaomi_prada
You can see that I previously created this for 3S, but I converted it into prada files, there aren't any huge differences.

One could flash a Redmi 3S Marshmallow ROM, but at the end reflash original boot.img to see If it boots.
Camera, Wi-Fi, and Bluetooth may not work, but If everything else is working, then only these 3 needs some changes in the Redmi 3S' kernel If Xiaomi refuses to release Prada's kernel sources

Unfortunately Redmi 4 doesn't have a subforum like Redmi 4 Prime, that's why I created this thread, as Redmi 4 is very identical to 3S in every aspect.

Yes, most likely I would brick the phone, but I don't have the phone yet because It is still shipping
I will give it a few tests once I've got my hands on it and my BL is unlocked

i tried to install the redmi 4's lineage os 13 rom on redmi 3s and it perfectly booted i just replaced the boot.img of redmi 4's lineage os rom with the boot.img of redmi 3s's lineage rom cant the devs port the custom roms made for redmi 4 for the redmi 3s

It can be ported.
Earlier I stated that you can just simply replace the boot.img with Redmi 4's stock boot.img, but the performance won't be the same as in 3S, due to custom made changes in 3S' kernel which fixes bugs in the open source kernel. Some things like GPS wouldn't work

Okay, it seems prada has Goodix fingerprint scanner, just as Redmi 3S
I still don't know why it is very similar to 3S
