Great work my man
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] neerajgoel:
my calling and sms not working after install. sim card is showing network and even mobile data is working.

but unable to make call or recieve call.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] king1990:
If you need volte to make calls , you can't use aosp ROMs. volte works only with oneui ROMs
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] neerajgoel:
ok. then how i can make calls and sms.

sir but how i can use sim service in aosp rom
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] king1990:
You can't , not possible.

The only to get volte to work is to flash oneui ROM.

Can someone help? I want to flash ArrowOS on Noble Rom 2.2. I tried doing it, wiping the vendor, data, system, and cache, but whenever I reboot, it just leads me to Download Mode. Is there a step I missed or something?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] alkh301180:
Your answer is pretty simple

As your Sim is Jio and only works with volte in calls, won't work with AOSP ROMs on Samsung as it doesn't support volte.

You'll need to switch to a One UI ROM. If you want stock Android 10 with Some modifications you can find Alexis ROM, Dev base, and more in XDA.

And if you want android 11 or 12 One UI Port, Noble ROM is available.

Good luck
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] neerajgoel:
Thank you so much for all the support

Quick question, does this rom support exfat?

If it does, can anyone help me figure out why this rom keeps telling me to format it when I stick in my OTG USB-C drive? It works fine in my S22 and it used to work fine when I ran LineageOS on this phone.

Also, there was a mention in the OP of a patch to enable encryption. Was that pacth released somewhere (like on Telegram or something)?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] king1990:
Here is EFE (Enable Force Encryption) flashable zip

* How it works It is a very basic script that will patch the fstab to enable encryption

* How to use :

Wipe clean.

Format data to ext4.

Flash ROM.

Flash EFE

Reboot.

REMINDER: ALWAYS FLASH EFE AGAIN AFTER ROM UPDATE AND BEFORE BOOT

Warning 1: Best used with ROM that come gapps version of arrow. Some gapps (like flamegapps) can't survive the encryption and will cause a bootloop after update

Warning 2: Any ROM update will overwrite the EFE changes and the ROM wont boot.

You need to flash the zip again to boot. While it will boot fine and nothing wrong will happen I will advise to not forget to flash it (so update manually/and flash the zip)

Thanks to thenist for his help and support to make this work properly

[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] p32929:
This ROM is better than any other ROMs out there for Note 9 in terms of Battery. Of course, there are UI glitches here & there, but those are manageable. But I'm not sure if anybody else faced the same bug, I'm unable to change my keyboard. When I'm focussing an input, it doesn't show any notification/option to change keyboard. Here's a screenshot. Can you please take a look? Thanks btw
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] king1990:
What do you mean ?

Maybe a problem with this keyboard. Gboard works fine here.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] silkshadow:
Thank you!!

Sorry but about Exfat support? Or any ideas why my OTG USB-C drive (SanDisk 512GB Ultra Dual Drive Luxe USB Type-C) doesn't mount (asks me to format it)?

It works in TWRP, I just used it to flash the encrytion zip.

I am setting this up for my niece and she needs both sim card slots. So she will rely on the USB C stick for school and stuff as the 128GB internal is not going to be enough.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] king1990:
Ah sorry missed exfat question, I will send you a kernel with exfat support to check if it works
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] silkshadow:
I am in, thanks! How shall I recieve the beta patch to test?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] king1990:
I will send it in pm
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] p32929:
Pardon me if my english is not understandable. I meant, the keyboard works perfectly fine. but when I want to change the keyboard from Gboard to lets say swiftkey keyboard, & I focus an input box, shouldn't it show a button or something where I can click to show the list of installed keyboards to select from? As you can see in the screenshot, I'm unable to change keyboard directly. Had to do some workarounds to change keyboard
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] king1990:
I understand what you mean now , i guess this might be android 12 thing that you can't change the input method directly from the keyboard.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] mrc99:
First, thanks for this ROM update. Very smooth operation except I have been having an issue with WiFi.

Every time I connect to a wifi router, whether at my home or other family member places, I keep getting a message that says I have limited connectivity. The wifi icon has an exclamation point next to it. Yet, I can surf the Internet and use F-droid and my weather app. I can't download email though.

Is anyone else experiencing this problem? Also, is there a way to not have to turn on Location just to have the wifi turn back on automatically?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] dloma:
Thanks for this excellent rom.

It feels smoother than my S21 Ultra somehow!

The only downside is losing High touch sensitivity

adding it would be appreciated.

Thanks so much for your hard work.

Awesome rom highly recommend it.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Fredol7:
Excellent rom, continue the great work. Please always keep the vanilla build. The other Android 12/13 roms are all bloated with Gapps.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] SOUZEGB:
HI I have question about this rom I've used this rom from beginning and after few days working normally but now I have sometimes random auto reboot and I don't know if this can be problem with kernel or something else I want to add I have rooted my phone also .
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] SOUZEGB:
And next my question there is a chance to flash zip which is can encrypted my phone without loosing data and root ? I mean I don't want to start everything again flash ROM and zip before boot because I have all done for now and I want to know if I can flash zip and boot normally to Android before I was trying and I fail so I give up but maybe someone know how to flash this zip EFE and boot normally to Android.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] SOUZEGB:
Please add also function to hide quick setting on lock screen.

[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Dontasy:
Hi since an app of mine really does not like root (tried to hide with magisk, but still it detects), I would like to use insular to sandbox this app.

I was trying to install but then my phone rebooted and it was failing to install. Tried with 'Test DPC' to see if this rom is compatible but it says 'App is not admin' even after enabling the app to be admin.

Now I am wondering if it is just me or if Android for work does not work with this rom?

Thanks for your awesome work btw, it is the first problem I was encountering after using this rom for quite a while <3

Edit:

I am using vanilla build with microg
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] UltraCenterHQ:
Honestly, my only complaint about this rom, is that you can't disable the swipe to switch apps gesture. Other roms had the option
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Fredol7:
nooo, why did you discontinue the rom for note9 :(
[Samsung Galaxy S21+] siminfrance:
I was trying to root my phone using Magisk but something went wrong during the final step, (was stuck on prism.img for +30 minutes)

Now, all I see is "An error has occurred while updating the device software" and at the top there is a red message "DN_FAIL_BLOCK_CUSTOM_BIN_OEM"

I have tried various reboot options to get back into download mode with no joy.

Even Smartswitch is not listing an "emergency recovery" option.

Any suggestion(s) as what I could do next?

Many thanks
[Samsung Galaxy S21+] siminfrance:
Ok, I got it sorted

download the latest Odin

download the latest firmware for your phone + region

unpack it all somewhere

copy and then rename the CSC file to remove the .md5 extension

That will allow you to "unzip it" and inside it there is a pit file.

Open Odin and set the path of all the md5 files, except for the last one, (USERDATA).

On the PIT tab set the path of the file you extracted earlier.

Plug the phone in

Start

And it should reboot fine.

You phone was wiped, you will need to reinstall everything

Before messing around with your phone ...

Make sure you know what firmware you are using

Make sure you know your country code.

Hope this helps someone...
[Samsung Galaxy S21+] dangercl0se:
Hey siminfrance,

I noticed in restoring your phone you have to download firmware for a specific region. Does the region specific bloatware come back? I need the bloatware back

Thank you
[Samsung Galaxy S21+] siminfrance:
Yeah, it has all the Samsung bloatware.

Not sure about all the countries, but in mine there is only one provider specific app and it gets downloaded automatically as soon as you first start the phone.

Make sure you get the correct Android version, (I got 12 in my case).
[Touch Diamond, MDA Compact IV Themes and Apps] Jazzfunky:
Hi Guys,

Just flashed my device to ROMeOS 1.13 from a Vodaphone branded ROM.

Everything works great and I am really pleased.. just needs a little tweaking here and there.. love it! One minor cosmetic thing is niggling me though and that is the fact I have lost my Volume Control Graphics (Slider) and in it's place is a traditional windows looking volume control.. quite boring really. Anyone got any idea of whether there is a way to re-install the prettier graphics slider and dump the traditional looking one?

Hi,

I flashed TWRP v3.4.1-0 from your link but I end up in a boot loop where I fail to mount any of the partitions.

View attachment 5783573

The DL Link for TWRP v3.6.0_9-0 seems to be broken. Do you have an alternate for that?

Note: I'm working on a TB3-850F.

Thanks!
[Android General] Viva La Android R.I.P.:
Okay I think dm-veriry is to blame. If you mounted /system after installing TWRP, dm-veriry will be triggered and the device will boot loop.

You need to flash a dm-verity disabler. I'll get you a link .
[Android General] Diznatch52:
Any chance you might also have a link to the updated twrp you had linked above? It's a dead link now.
[Android General] Viva La Android R.I.P.:
Sure. I'll fix the link
[Android General] Viva La Android R.I.P.:
Ok link is fixed. Follow these steps.

Warning: This will wipe all data from your device.

Download the no-veriry_opt encrypt file linked below and save it to an external micro SD card. Insert the micro SD in your TB3-850F;

Install TWRP v3.6.0_9-0 and reboot recovery;

Select Wipe, Format Data, and swipe to commence.

Select Install and navigate to the saved location of the no-verity zip you downloaded in Step 1. Select the zip and swipe to commence installation.

Reboot system

no-verity_opt-encrypt_v6.1.zip

If you want root access of the Android OS, install a Magisk systemless root script after Step 4.
[Android General] Diznatch52:
Awesome! I'll give it a shot.
[Android General] Viva La Android R.I.P.:
Download Magisk v24.3 from this link https://mega.nz/file/4c43FbwS#Qd-pKoupa8LZ-EI9qe5Zsr3L4rSz8NDv2Ojknrd8sCk

Install it after Step 4 if you want root. After you are booted, you can update Magisk to the latest v25.2 using the Direct Install option.
[Android General] Diznatch52:
For some reason, after this process, running `adb reboot recovery` brings me to an android crash screen. Any idea why?
[Android General] Viva La Android R.I.P.:
To confirm, this procedure did work and you were able to boot into the OS? Once you confirm I'll try to resolve your ADB issue.
[Android General] Diznatch52:
Yes.
[Android General] Viva La Android R.I.P.:
Ok download the official TWRP App, grant it root permission, and flash the TWRP v3.6.0_9-0 to the recovery partition. Reboot your tablet and then try the adb reboot recovery command again.

When you flashed the original TWRP with fastboot, did you immediately boot into recovery and flash TWRP again using the Install>Image option?
[Android General] Diznatch52:
As soon as I unbrick this again, I'll give it a shot :p

Edit: booting into recovery now gives me twrp! Thanks so much!

Now time to see if I have better luck flashing lineageOS
[Android General] Diznatch52:
IT WORKED!

Thank you so much!
[Android General] Viva La Android R.I.P.:
Anytime friend. Glad it worked out.
[Android General] Viva La Android R.I.P.:
Update: December 13, 2022.

I am presently working on bumping TWRP up to v3.7.0_9-0.

The v3.7.0 base build includes Python support for Android Oreo & newer versions.; keymaster API V1 fixes; fixes on copying sepolicy on devices with no /vendor partition; several fixes on custom theme support as well as perfected ROM multiboot functionality. Also, I am updating my implementation of PIGZ compression for data transfer speed improvements and enhanced protection against data corruption. Stability improvements and minor bug fixes also included.

I will keep the OP updated with an ETA.
[Android General] Viva La Android R.I.P.:
I have a build of LineageOS 14.1 that I optimized, fixed some bugs and removed settings entries on SIM cards & mobile networks. Open source libraries have been updated and the security patch level bumped up to June, 2022. GApps have been removed and several performance enhancements have been added. I'm without a working 850F at this time, but I should have a working device soon. I will post the LOS 14.1 build as soon as I can fully test it.
