I have done the following steps (in this order) to update my Samsung Galaxy S7 Edge using Odin:
- Downloaded and installed the Samsung USB driver on my Windows PC
- Enabled USB Debugging on my phone
- Booted my phone into Download Mode
- Opened Odin (v3.12) on my PC
- Connected my phone to my PC (confirmed connected by Odin)
- In Odin, selected the BL, AP, CP and CSC (intentionally instead of the HOME_CSC, as I wanted a reset as well)
- Clicked Start
It has now been 1.5 hours, and the phone's Download Mode screen is still showing "Downloading...".
Did I do something wrong? It's not meant to take this long, is it? (I read that it's meant to take no more than 20-30 minutes)
EDIT: after over 2 hours with no change, I force reboot my phone, after which I was greeted with the following error:
"Device storage corrupt. the data partition has been corrupted. you
need to reset your device to factory default settings. this will erase
all your data"
I am now downloading the latest UK Oreo ROM, which just came out yesterday, in hopes I can manage to flash it successfully and that I haven't bricked my phone beyond repair...
