I have a sim card which has stopped working, my network provider cut me off after not topping it up regularly enough. This sim card is 11 years old with tons of business contacts in whatsapp and vital messages I need restoring. I just recently went through a process to upgrade the ROM without thinking and although that failed to work out, I put the old rom back only to find out i can no longer restore my original number with all those contacts on. Before I started to flash the ROM i did make a manual whatsapp backup to drive.
Now, I have a new number, installed whatsapp and I have no option to restore the backup from the drive I did earlier on the old number.
Is there any hope here for me to restore my old backup to the new number?
