I have been searching more and more about Flash memory and arrived on non-volatile items; as far as my understanding goes, non-volatile items (or nv items for short) are the "unchanged" items in the system.
nv items include: IMEI, PRL, MRU and etc... but what's happening when backup & restore are taking place? Will nv items be "un-touched" or overwritten?
Also, where can I find more about android backup & restore process and nv items?
Thank you very much for your time!
