Unfortunately, there is not a workaround other than all the resources I mentioned, and that those files are available, in all of these forums, search on the Realme 6 and 7 forums, I downloaded all from there. I solved all the issues less the IMEI, but with baseband working fine, so no problem, good signal and connection.And still my current issue facing is my camera not working also the other sensors same as for the IMEI null but the Bluetooth and Wifi is working fine
