[ROM] [R] [ONE UI 3.1] [G988U] [G986U] [G981U]

[Krog18]

This ROM is based on Android 11 One UI 3.1 for the Samsung Galaxy S20, S20 Plus or S20 Ultra 5G Snapdragon with modified firmware to allow for a safe update while retaining bit 1 to keep bootloader unlock. This ROM uses the AIO userdata image created by @jrkruse to automatically flash TWRP, Magisk and all of the fixes that we need for our rooted devices. Link to AIO thread here

Flash at your own risk! I am not responsible for any dead device, loss of data, etc.

Requirements:

• Must have an unlocked bootloader
• Modified odin to flash ROM

Instructions:

• Back up any important data because this will wipe your internal storage
• Download rom for your device from below and unzip ROM to PC
• Connect phone to PC and load all 5 files into odin. *If using no wipe userdata, your lockscreen pin will be reset to swipe so you'll just have to set that again when you boot into system
• Press start
• When it's finished, phone will reboot and automatically boot to TWRP to format (wipe) data. Then phone will reboot to TWRP again to flash some files. When it is finished, the phone will reboot to system
• After you finish setup wizard, open rom control, allow root access and open each tab to set default values

This looks awesome! Is it 3.1 based on android 11 or 10?

Can you confirm if this ROM addresses the issue where the display dims when you are talking on the phone. It gets so dimmed I cannot even see where any button it is to get the screen back to bright. I end up pressing on the screen and many times I press a button inadvertently and sometimes it is the hang up key. The most dreadful feature of Samsung.

It is Android 11

I haven't seen this issue. If it happens to you on full stock, it could be a hardware issue with your phone. Make sure you don't have anything covering the sensors that are up near the front camera on the screen.

It is a common issue. I don't want to clutter the ROM Q&A but here is just one of many links (https://us.community.samsung.com/t5/Galaxy-S-Phones/Screen-dims-when-making-calls/td-p/319723/page/4). Apparently the right setting varies by phone type but I am using S20 Ultra+. I am simply looking for a ROM where I can override if the phone is active (either by touch, motion if not logged out, etc. the screen does not dim). Thanks

This seems promising, will it work on SM-9880? since its both snapdragon?

can you make a rom for s20

 

[Krog18]

This seems promising, will it work on SM-9880? since its both snapdragon?

No, it won't as it is. I'd have to build one specifically for the 0 variant. I'll see what I can do after I get the U variants taken care of.

can you make a rom for s20

I can. I have one for G986U just about ready and I can build one for G981U next

[scepz]

[adminbaby1]

[ywhuangc]

great,thanks，ivery like this rom,wish update continue

 

[ChongoDroid]

ROM works great.

I noticed scrolling screenshot is broken (it was on my stripped down build of DUH2 as well and I'm not sure what broke it)

It's working for me. Did you maybe debloat something you shouldn't have?

 

[Gianni's]

Can I flash this rom on g9860?

 

[ChongoDroid]

It's working for me. Did you maybe debloat something you shouldn't have?

yeah I think that might be it. it's weird because I had it on my regular install of duh2


basically the screen scrolls but if you click it again after one scroll it'll stop scrolling and it includes that bar at the bottom of the screen shot

 

[ChongoDroid]

so this is what happens when I scroll a few times, sometimes it's 1 or 2 times.

Try uninstalling updates for screen capture app


Edit:
I was able to reproduce this. It seems that there might have been a bad update to the Samsung capture apk, but the version in the rom is good. You can go back to it using the method described above. Then I updated to version 4.8.04.2 through the galaxy store and it seems to be working well so far

@Krog18

Thanks very much for this rom, it's running without issues for me


Question...what does modded theme store mean specifically? I went looking for themes and there were paid and free ones like it's always been. Maybe I was looking in the wrong place, is there a separate section for themes that are trials?


Edit: nevermind, I clicked on one of the paid themes, and I see an option for "download trial" I'm assuming that's what you mean, unlimited trial?
