Possible in theory. Don't know about smsd - maybe a log file for every write
access
will reveal that?

According to different manufactures EEPROM cells have a life cycle of upto 1
million
erase/writes with at least 5ms access time. That means 83 minutes of continous
write
to one and the same cell (IMHO unlikely).

btw: a skilled person can "easily" change the flash chip (of that 7110), even if
it's BGA
or uBGA. I did already just with a hot flow rework tool and some soldering paste
(I apply it
with a finger tip and let it melt so I get almost all ball pins with the same
amount of solder.
I can share my experiences with people who are interested in. Just email.
