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?

      do you guys experience battery drain because of the "Cameraservice_worker wakelock" when walking around with the phone?
      Found some intresting. Wrote here on post #161

      Now a days it's really very very hard to hard brick device. Only condition I know that easily hard brick your device is
      Flashing bootloader with twrp (specially bootloader file is corrupt / wrong)

      Always flash bootloader files (with md5 extension only) with odin.
