I ran into this weird situation, where :
- I backed up my whatsapp to local storage, inside : Databases Folder
- Then i changed my whatsapp Number ( To another New SIM )
- Format my HTC Phone ( HTC E9 plus Dual Sim ).
- Copy back all Whatsapp Folder back to : Internal Storage
- Re-install Whatsapp, but, all it asks me is this (below) & upon SKIP, nothing, no chat restored. ( I have already renamed databse file, as per : https://faq.whatsapp.com/en/android/20887921/ to msgstore.db.crypt12 & also, i keep same file, with name : msgstore.db.crypt. But, it simply, doesnt even DETECT it & asks NOTHING as BACKUP found / Restore. Any GUess / Idea ? Plz help.
