    Jumptoheaven Yes that is what i saw a while back, do you think it will work on my galaxy folder 2? Also where do i find my phones stock ROM folder to find the NVRAM file, the one i have is samsung's divided into AP,BL etc.?

        Kgr I found a root file manager app but still cant find the .Nvram, anybody know where its located so i can pull it?

          Jumptoheaven Techgen Oh I understand now. Just curious: Would people have the same question to take from one oneplus phone for use on another, or specifically the f30?

            Kgr nvram is a separate partition (root file explorer allows you access to the system partition, nothing else) you will need to dump the nvram image, edit it with a hex editor and flash it back to your phone. You won't need mtk engineer mode (your device probably doesn't support it anyway).

                whynot Ok so i have a root file explorer how do i dump the nvram, i cant find it.

                  Kgr sorry if I wasn't so clear in my previous post. Root file explorer won't help you because it only gives access to the system.img while nvram is a separate image. How did you root this phone? Did you use a tool to pull boot.img? If you did you could use it to pull nvram.img . Or if you got the stock rom you could open it and find nvram.img

                      whynot So i rooted it with magisk. The Stock Rom i downloaded to patch and root isnt really openable, since this is a samsung device and its stock ROM is split into .md5 files.

                          From a root adb shell you can probably dd partitions to sdcard and pull them that way. Maybe look for /dev/block/by-name/nvram
