SwiftBackup as built-in in ROM

SwiftBackup got update today and having new feature added - Annonymous Account . Here you can use SwiftBackup without having login to google acc. Also it will be free app (No premium Fs) so you can easily backup-restore apps + data soon after clean installing ROM. I will include in ROM installer (Titanium will be replaced by Swift Backup in aroma) in next version of ROM
In case you have SwiftBackup subscription (Paid version), same app you can use to enable premium fs by just login with your google acc
I hope this will make clean installation process more easy.

Latest version Swiftbackup doesn't start anymore ( FC because of 'unofficial code detected') when Xposed hooks are enabled After disabling it works fine again 😏

Hi Dr Ketan and everyone.

The reboots that I mentioned in my previous post occurs exactly when charging the phone from 69% going to 70% and 84% going to 85%.

I don't have any magisk modules installed except for the ones that came with the rom.

Any idea?
Taking log will be helpful, nothing I can know from this info. Alternatively, flash Stock A12 and start from scratch.

I have successfully flashed S05 and everything looks good. Since there are some apps that does not work well now I Odin flashed A12 BULF and thay went fine. Only problem is that the bootloader is still locked. A warning pops up every time the device boots.
Tried to search XDA forums and Googled for a solution, but end up on how to do it on a Snapdragon version.
Anybody know how to do it on a G998B Exynos device?
Thanx

Instead of searching Google, it is best to read Changelog. Every line is important. Go and find, ROM itself have option for this.

Hi again, I'm sorry I didn't explain this well enough.
I did find how to remove this boot message after S05 was successfully installed. That worked fine 😊
The problem is that I wanted to return to stock and after a successful clean stock Odin flash (BULF) I now get this message every time the device is booted running stock.
I thought that the bootloader would automatically be locked and the OEM switch reset. Seems like this has changed after my older and current Note9 device.
Thanx...

Oh ok. You needs to relock bootloader, from dev settings + from download mode

Я успешно прошил S05, и все выглядит хорошо. Так как есть некоторые приложения, которые теперь плохо работают, я прошил Odin A12 BULF, и все прошло нормально. Единственная проблема в том, что загрузчик все еще заблокирован. Предупреждение появляется каждый раз при загрузке устройства.
Пытался найти решение на форумах XDA и в Google, но в итоге нашел, как это сделать в версии Snapdragon.
Кто-нибудь знает, как это сделать на устройстве Exynos G998B?
спасибо
Set the date and time manually instead of automatically and reboot. If it doesn’t help to update the phone through the settings, it’s more accurate not to update, just look for updates and reboot everything, the factory unlock item will appear
 
I got a notification about an LSPosed update and just accepted. Actually everything went well but SafetyNet fails now and Magisk Hide did disappear.... However, all my apps (incl. GooglePay and several banking apps) are still fully funcional and I can't see any disadvantage by not passing SafetyNet.

    Hey, has this been updated to the latest May firmware release?

    Hoping to receive my device tomorrow, can't wait!

    Wondering also if there's any telegram group, for this custom rom or s21 ultra generally?

    Hi. No, it has not been updated to May firmware, but Dr Ketan is usually pretty fast and aware of every new release.

    I'm not sure if I'm allowed to say this, but I would recommend getting the pro version, it's a way to appreciate the effort put into this.

    Regarding telegram groups, I know there are a few S21 ultra groups, but I'm not a part of any, nor this ROM has one (AFAIK)

    Installation and Download & Notes


    Important :


    - This will void warranty.
    - As of now you will lose Samsung Pay and Samsung Pass forever if you root once, even unrooting won't help. (hope in future we can get it working on tripped knox device)
    - OTA won't work once you root device.
    - ROM Tool permission : Files & media - To save and read files, Calendar - Tool needs some time monitoring to avoid using RT immediately after reboot. Special access for accessibility service - Since Android 12 it requires for QS panel custom Toggl e.g. Reboot to recovery

    Installation :


    Read ChangeLog post for Installation instructions (link on post #3)

    PS : Who can handle consequences of dirty flashing, they never need to ask this question in forum. If you dirty install then handle it yourself .
