I deleted my OS on my phone using twrp. I am now trying to reinstall the OS I deleted. The model of phone is a Samsung 5 SM-g900w8. The carrier is Telus Mobility in Canada. The steps I have taken so far is copy a ROM on to a SD card and insert it into the phone that is not working. When I do this TWRP does not show anything on the micro SD card. The second method I had tried is using fast-boot. I tried push the ROM on to my android device. Both methods I tried failed because I am probably not doing the steps properly. I am not even sure if the ROM I am using is proper. I have been searching the internet and don’t even know what I am looking for. I found one site and download the ROM hoping it was correct. Where can I find correct Stock Rom for my phone? Maybe I could not push using fast-boot because I do not have the correct file? Why is the SD card showing (0)MB
Thank You for your help. Its will be greatly appreciated
