hey guys, need some help here. I messed up something during ROM installation and wanted to flash stock firmware using Odin and then start the process again. I downloaded the latest firmware using Frija tool (Model G998B, CSC: BTU). First of all is that the correct CSC to put in Frija or doesn't matter? This is the error I'm getting in Odin. I think it is saying I am using an older bootloader but I'm not sure so was wondering how can I go back to stock firmware and then try to install the ROM again?

Edit: I am still able to get to TWRP if I need to do something from there.

Why not try and flash the rom again, following the clean install instructions, factory reset etc... Don't forget to flash the BL, AP files etc as provided in the zip.

Is there any way I can disable remote support in device settings? Any time I click it it downloads smart tutor apps from playstore and wanted to disable it with adb but I'm not sure what the package name would be. I am using t-mobile on this phone if that helps.

1. Will this update use the Same super.img file as R03? If so, saves me from copy and pasting to my phone again...

2. Dirty flash AOK?

Try this.
Download > extract and and push on data/adb/modules/ViPER4AndroidFX/

overwrite if existing

set permission 644

reboot and see how it goes..
thanks for the instructions, I got it working finally. Just a weird issue i'm having, I copied the presets to data/viper/files folder but I can not get them to load. Or even when I create the preset and save it, it doesn't show up. Any way I can fix that?

    bmonteiro and Other test users​

    Kindly post your full review about SB1 as well about OneUI 4
    I have installed since two days but hardly opened any app other than settings, just spent two days to prepare ROM for users so any one can install it without going through pain of installing official beta. I have really no idea what is new in this beta. Code wise there are lot differences. Also samsung and google started behaving like apple and making tough for modification with every OS update. Let's see how further development goes!

    I'm on the ROM for about 3 hours now, no random reboots or anything of the sort.

    All my apps are working properly, made some calls successfully. Was not getting notification, but I noticed that now all apps that I open are asking for notification permission, so not a problem, just something to keep in mind.

    Some fame drops here and there, but I'm following the other thread where non-root users are also reporting this, so it's not related to this one being custom. Another thing for users wanting to trying out this one is that Safetynet will not pass, even for non-root users beta versions does not pass safetynet.

    Besides that, One UI 4.0 is almost identical to 3.1, some new features like battery protection, extra dim (which I really like)

    Can't say anything related to battery yet as it's too soon.

    - OTA won't work once you root device.

    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 .
