Model ZTE N9500 Carrier: Sprint
Messing around with various button combinations I found this one and up popped a very interesting menu my question is. What are the respective purposes / consequences of each choice .
1 ) reboot( self explanitory)
- apply update from external storage.
3 wipe data/factory reset.
4 wipe cache partition
5 apply update from cache
6 md5 check
7 wipe carrier/data/factory reset.
Thanks in advance, Chris
