Dear User,


Your device is rooted. For the IMEI repair - you have to use the latest added method, which will require a rooted a phone. You do not have to downgrade the device.

can't downgrade boot loaders

If your phone with the latest firmware and the frp blocked Do not try to downgrade !!
You can not downgrade AP SW REV because if you are in Binary security bit 1, You can only flash firmwares with Security bit 7.
With SW REV That you can not downgrade.

You cannot downgrade this new firmware.
If you flash any older sboot than you will get binary error because of Samsung roll back protection on this very new firmware!
If you flash any older modem than you will get UNKNOWN BASEBAND.

The Samsung Galaxy S7 SM-G930W8 model has Imei repair functions supported:
Repair IMEI & Patch Certificate
You can root with CF-Auto-Root and then patch the certificate keeping the same binary without downloading the firmware version
