Multiboot and s9 - Samsung Galaxy S9+ Questions & Answers

After searching and going through every topic I could over in forums, I couldn't find any multiboot solution for Galaxy s9/+. So I have two questions,
Is there any multiboot solutioj available so users can keep two roms? Maybe a TouchWiz one and AOSP for secondary flavor?
If yes, do you think the specific partition style that GSI requires is something that can work along with the multiboot logic?
Thanks you.
PS: if not availablee, do you think it's something that deserves a bounty thread?

Any Custom-ROM-Flash-issues between different space-variants?

Hello,
very short question: Does there exist any differences between the different S III models 16- and 32-bit when i aim to flash custom ROMs on the device?
I want to flash at least CM 10 or CM 10 based ROMs (hopefully paranoid ROM for example) on it.
I really searched on google for it and did write "xda" behind it to find topics on this forum about it but maybe this question is too trivial that noone asked that question yet.
But in germany we say: There are no stupid questions... just stupid answers!
PS: Sorry for the title!
No differences!
Rom will works on both variant

The CM team isn't likely to see this message here at XDA, just FYI. You'd be better off contacting them through the CyanogenMod forums.
I can probably semi-answer this one, though ... many of those dialer codes were put into the Android OS by Samsung, they weren't part of AOSP. As a result, somebody would have to figure them all out, program them in, and provide apps for them to launch, which at this point is pretty unlikely given the age of the Galaxy S/Fascinate. I believe the are ways to communicate directly with the modem using USB "ACM" mode on most kernels (FWIW, my kernel does not have this feature), but it will most likely be from the command line and not the GUI.
That said, many of the features you want/need have likely been thought of and may be accessible in CyanogenMod, but you'd really want to ask them directly, or perhaps even better ask as part of the development thread for the specific CM-based ROM you want to use. My suggestion would be to ask how to accomplish what you are trying to accomplish rather than asking why the dialer codes don't work, that way alternatives can be suggested without putting people off! :laugh:
where i found part of the development thread for the specific CM-based ROM?

Well, not to be short with you, but if you know that the ROM doesn't support the dialer codes you want, you got that ROM from somewhere, maybe try that thread?
There are also official CyanogenMod forums, easy to find with Google.

Building a ROM from scratch, guide?

Are there any guides that show the user how to create a rom from scratch? I've seen multiple guides on creating a rom but they do so using the kitchen. I would prefer something that shows how to make a rom without a crutch.
please help

I would say the best way to make a ROM from scratch is to compile it from source. If your interested in learning how to compile a ROM from source I would recommend taking a look at this guide to building Jelly Bean from source, as well as Google's offcial documentation on building Android from source. Additionally this guide on Zip Based ROM tweaking is a good guide to take a look at. Let me know if you still have any questions .

Normally all device forums have tutorials on how to compile ROM from source(if someone has already compiled it).
If no development has yet started for your phone then you you need to create the device tree which is tough. Otherwise just google . There are lots of tutorials lying on xda.

Thanks, I didn't even know there was an official guide
I'm wanting an AOSP ROM on my s5 g901f but there is no support at all. Could someone point me in the right direction? I'd like to have a go and have looked up porting but I don't think that is the way to go. If somebody could give me the steps what I need to do for this modal I will research.
Could I use the cm for note 4 as it has similar specs, ie
805, 420 etc. Or s5 g900 as a base ROM? Or would I need to build from scratch?
There is only one custom ROM for g901f and that's touchwiz so somebody please help before I go insane. Touchwiz really is that bad
Up for this. Really interested especially for us who has not so good programming skills

Let's see if I can point you in the right direction! Because of the differences in specs between your S5 Plus and the regular S5 you can't use that to port ROM's. For the Note 4 idea, since you only have a Touchwiz ROM as your base (The one from your S5 Plus) it won't work properly for the port ROM (CM12 Note 4). I would recommend looking at compiling CM12 for your device, which I would recommend taking a look at this guide here. Let me know if you have any questions be happy to help you out.

Available M4 Aqua ROMs with the Least Google

Hi,
I think the title says it all.
I really don't want to get into why/why not do this. I'd like to use a least-Google ROM on the M4.
How much of Google's services is in a stock Cyanogenmod ROM? Do they all have the optional add-on to flash Google services or they're in-built from the start?
I'm interested in trying the unofficial Marshmallow ROM here. Or even more so I'd love MIUI on M4, but we don't have it, even unofficially.
Thanks for the information, I'll build a rocket-ship out of it.
In all seriousness though, I think you do realise that there aren't enough developers for the M4 Aqua, and it looks like the ones who are here don't have enough time to build a MIUI or a stable AOSP ROM. I don't know what you're trying to say here, but if you're looking for the ROM with the least bloat a quick search can help you find the relevant information.
Thanks for the information, I'll build a space rocket with it.

Nah go build a ROM instead, you'll be doing the community a favour instead of posting useless threads

I've seen people post threads about this topic for practically every smartphone I've owned. Apparently it's a common question.
There's nothing more to learn here so I won't check back.
Cyanogenmod ROMs in stock don't have any apps from Google. They're Google-free. But, there are unofficial gapps packages (flashable Google apps), to get Google apps back. Unforunetly, there isn't a single stable CM for our device.

Is there any available dualboot(multiroms) solution for new devices and Android 9.0+

According to @Feherneoh 's posts in @m11kkaa 's EFIDroid thread, EFIDroid which might be the best Dual Boot(Multi Rom) solution in the past cannot support arm64 and Android 9.0+, and somebody seemed to have begun to rewrite. No news about rewrite for a long time.
DualBoot Patcher also doesn't support Android 9.0+. And its author @chenxiaolong announced that DualBoot Patcher was no longer being developed 2 months ago.
Other solutions, such as MultiROM stopped being developed even earlier.
Can anyone offer some useful informations or suggestions about dualboot for new devices and Android 9.0+ ?
Thanks.
Any help?
Thanks
Any informations or suggestions?
Thanks
bump almost a year later and no answers...
