I got several samsung mobile phones, and as tech as I got in the android EcoSystem -- is using samsung kies, or some apps filemanagement on the mobile phones.
Now, after one of my mobile phone got stuck while loading the system (to say exactly what happened -- is that for somereason after something was ran in the device -- I do not know whether it was a firmware update or something else -- the mobile loads and get stuck on the samsung logo)
None of the mobiles I got is rooted. And all the apps are -- as far as I know -- valid and none intrusive.
I been trying to figure out the following, in order to backup/restore Firmware/ROM:
A. Is a FirmWare (as samsung call it) is a ROM?
B. What is the procedure backing up a ROM from existing mobile device. Do I have to have root access to the device, or can it be preformed with a simple app.
C. What is the procedure restoring ROM.
D. Where can I get official Samsung FirmWare/ROMS for my mobile devices, and save them as files for later use? (I read on the web, that while the samsung Kies download the official ROM from their site -- it saves it in a temp dir, but doesn't save it for later use)....
E. What tools/procedure do I need -- in order to preform BackUp/Restore of ROMS?
