So I have a deceased friend who I had a bunch of old texts from in my phone...my phone had a brain fart and i NEEDED to do a factory reset to fix it.....I downloaded a sms back up and restore app and I backed up my files...i deleted a thread and pressed restore to make sure it worked..i then emailed myself the backed up file and proceeded to reset my phone.....I redownloaded the app and now it wont work....The file that I have is in a .db format and ive noticed that the others in the tutorials are in .xml or something....why did the test work and now it wont restore??? These texts are very important to me and I would really appreciate some help getting them back... i don't know what else to do and I am heart broken that theyve dissapeared.
