HWL1 still uses HWJD modem
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] ExtremeXT:
Well, that's weird then... Could you try flashing this image before flashing the ROM?
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] TurricanM3:
One thing i don't like about OneUI6: Why doesn't it boot up completely? Every time you restart the phone the Ui is only loaded after unlocking the phone "Smartphone is starting" (or something, got it in german). This is way slower than before with 5.1 especially if you want to start an app afterwards.

Is there a way to get it like before? Full boot up without unlocking first?
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] ExtremeXT:
I've always had it like that lol, maybe it was a tweak of your previous ROM to remove it? Why's that an issue though, do you reboot your phone 10 times a day?
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] TurricanM3:
Hm i never experienced this. Weird.

It's not that big of a deal, but with auto restart you have a slow phone every day the first time you unlock it. Apps need way longer to start because everything is loaded at once. This is a downgrade for me. But don't get me wrong, this ROM is awesome i never wanted to go back to 5.1.

So there must be a preload feature. Wonder how you can activate it?
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] ExtremeXT:
I think it's rather a framework patch to disable authentication before finalizing system boot-up.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] Arenischen:
I've also experienced this, My mother has an s20 Ultra that had white flickering screen, sometimes it went back to normal, one one of those occasions I decided to try this ROM and voilà, no more white flickering screen since flashing (about a week ago). Maybe its a "bug" Samsung introduced to the s20 series idk, but also wanted to say thanks so much for this ROM!
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] gabrielfrias:
Thanks for your reply. I was wondering if it just happened to me, so my suspicion is true: updating S20+/S20 Ultra to Android 14, does actually solves the problem. I guess Android 13 has as deep code issue that causes this, and they didn't manage to solve it with normal updates, but they did in Android 14, wich is not officially supported to S20 series. This ROM is magic! lol
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] ExtremeXT:
I'd say it's rather planned obsolescence to get people to upgrade their devices.

Hello, is it possible to install a clean Android 12 from this rom? I need android 12.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] ExtremeXT:
Only Android 13, OneUI 5.1
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] Mateuszz:
And if I upload 13, can I then go down to 12? I have s20+ 5G.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] ExtremeXT:
You can't downgrade to Android 12 after flashing 13 or this port.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] Mateuszz:
This is a bit of a bummer, I bought S20+ and it was already on 13 and I wanted to try Lineageos 18.1 because LineageOS is not available on S20+, by the way, I wonder if it will be

I have an issue, I had it on both v3.0 and v3.1.

When I crop a photo using Samsung Gallery app, app crashes IF the photo contains a motion photo. When I delete motion photo then I can crop it normally. :/
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] CoopZor:
I found a good guide for this rom :

A few questions before I begin with this mission :

1. How is overal performance compared with android 13?

2. Does everything work? video said camera app has minor problems.

3. How is battery life? I have a s20 ultra 5g, stock android 13 and I get 8 to 9 hours of screen on time which is quite amazing, will this be the same with this rom?

4. I don't know want any root, can banking apps still be a problem?

Thanx everyone, and especially Extremext!
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] Kinglos:
1. The overall experiance and performance is way better on OneUI 6.0 compared to OneUI 5.1 (You would be surprized)

2. 99% of camera functions and moods work including Night Mode so you don't have to worry about that either.

3.Battery life is almost similar to OneUI 5.1 or even better with the new OneUI 6.0 optimizations and there are some scripts that you can run to have the battery life even better.

4. Banking apps run without any issues just use KernelSU to root and you will be all good.

ExtremeXT did actually make the most out of this device including that the device is now identified as S21 Ultra.

Play Integrity is already there by defult in the Rom so you don't have to worry about Google Play Certification which is a bonus point.

Try the Rom and I'm sure you are gonna love it. If you don't tho it's pretty easy to roll back to your stock Rom
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] CoopZor:
Awesome dude, Thanx for this post!

I'm not interested in root, so I don't have to install kernelsu or anything like that?

I will install it tomorrow, I was already very happy with my s20, maybe this makes me super happy 🙂🎉
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] nikoman1987:
Hi. Without root your device won't pass Google Play certification. You can root the device whenever you decide , so don't worry if you don't do it at the beginning. Also you can join the ExtremeROM Telegram group for further help and questions.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] TurricanM3:
Everything is noticably faster. Task switcher or keyboard popup, switch between apps etc (animations 0.5x here).

Only thing i find annoying is the slow start after every restart because the ROM only gets fully bootet the first time you unlock the phone. This is no ROM issue, it's normal for 6.0. But besides that this is overall a much much better/smoother experience than 5.1!

See known issues in first post. Some unmentioned features like scanning documents doesn't work as they should. You have to crop them manually.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] CoopZor:
I'm from belgium, we have an app here called itsme, we use it to sign things and such things.

We can't hide root from it, I tried it many times on my previous phone with magisk.

So I never used or needed root.

This is really a bummer...
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] kalpak2021:
I feel that the 3x tele camera is using a crop in from the main sensor as the exif data shows an aperture speed of f/1.8 which indicates it is using the main sensor, any way to further clarify this? The quality is also noticeably inferior to as when on the stock Android 13 (OneUI 5.1) ROM.

installed the ROM, and everything went ok.

Only thing is, i cant reboot into TWRP anymore.

Turn phone off, hold volume up and power is the right way to do it ?

From what i experience now, this ROM is way better then standard ROM.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] nikoman1987:
You need to connect the device while it is turned off to a USB cable connected to your PC , then hold VOL+ and power button. This is how you boot to TWRP on newer Samsung devices. Or with root - you can directly reboot to recovery via Magisk or KSU
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] ted5300:
Please try to put the USB cable in the phone. Power off and then hold volume up and power with the cable connected to computer.

[Galaxy EXYNOS S20 S20+ S20 Ultra Development] kalpak2021:
S20 Plus.

Also, the device is currently getting noticeably hotter than the stock rom. Any particular reason? Is it possible to improve the thermal management through software or is it due to the ROM being a port, coming from a much more powerful device.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] Kinglos:
Try using KernelSU instead of Magisk as it's very bad at hiding itself. I had the same issue here with a Malaysian Banking app and it only worked when I switched to KernelSU for root.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] CoopZor:
Alright, a few hours in to this rom and I love it!!!

I did not use root, working great with banking apps.

My phone flies! I love it!!!

Thanx Extreme!
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] KrinKillaz:
Im in belgium also, both on extreme 3.0 and beyond 6.9 rom i can use itsme, kbc, ing etc, everything works, you're doing something wrong, on extreme 3.0 it just worked out of the box, on beyond 6.9 i had to install kitsune mask magisk

.. Than enforce su list and hide magisk, no modules installed..

Edit - remember to uninstall magisk app after installing the kitsune app. But not before, ylu need to give kitsune root permition to modify your magisk, do a direct install, tjan reboot, than unninstall magisk, activate the 2 options i show in screenshot, than clear your playstore and itsme cache, restart, should work well after that

S20 Ultra here
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] CoopZor:
Thanx @KrinKillaz.

Good to hear it finally works with itsme, a year ago on an other phone I and many others couldn't get it to work.

For myself, I don't see any benefits in rooting anymore.

I run extreme rom (very smooth experience as you know with great battery life) , run fps limiter, have no adds in YouTube Twitter and reddit (Thanx to revanced).

Why would we need root these days?
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] kalpak2021:
I'm back to report that the ROM has been working flawlessly and the heating issues have reduced considerably over time. Idk if it is something to do with the usage pattern or if the software intelligently learns your usage patterns and takes a while to settle down. But the ROM has been working really well and the battery life also seems to have improved over time.

Good job ExtremeXT. Superb job doing this for the community. Deserve all the credit.
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] ExtremeXT:
Thank you for your feedback and kind words! The heating issues after installation are likely a combination of AI pattern learning which Samsung added in newer OneUI releases, combined with the fact that it's a backported ROM with modified frameworks and APKs, this means that it doesn't have predefined caches for apps like Settings, so it will spend some time building them as user caches before it stabilizes to normality. Nothing I can do about it unfortunately.

If you have thousands of pictures in the phone or SD Card, the phone may be sluggish and heating up when it is busy building thumbnails and face-data. It would work fine after the process is done.

ExtremeXT's Play Integrity Fix fingerprint was banned. Use Official Play Integrity Fix

Affects:

Apps that check Play Integrity

Google Pay

Device integrity in Play Store
[Galaxy EXYNOS S20 S20+ S20 Ultra Development] ExtremeXT:
IMPORTANT ANNOUNCEMENT

Google has banned the fingerprint present in the PlayIntegrityFix ExtremeROM v1 module. It has only been created because @chiteroman, the original author of PlayIntegrityFix, has stopped providing fingerprints at that moment, but since he started including fingerprints again, we no longer need a custom version.

TL;DR: To fix Google Pay, banking apps or anything else that requires Play Integrity API and/or Google Play Certification to pass:

1. Uninstall the current PlayIntegrityFix in Magisk or KernelSU

2. Download @chiteroman's module: https://github.com/chiteroman/PlayIntegrityFix/releases

3. Flash it

4. Reboot

5. Clear data of Google Play Store and Google Play Services

ExtremeROM v4 will come with Play Integrity passing out of the box without any module, so stay tuned for that! But for now we have to use the module, so, enjoy, and sorry for the delay for this announcement.

Thanks to the developers for their hard work.

Unfortunately, the English language is not very good for me, so I would like to clarify the installation of the 3.1 add-on.

I have problem with two apps since the day that I installed your ROM. It's about Gree+ and Ewpe Smart (they are identical). Applications don't even want to open, they immediately FC and go to the main screen. I thought it was Android 14, but both work on my wife's Galaxy S24.

So today I made a logcat and this is part of the errors.
