Hello. I want to upgrade my Toshiba e740 to 2003. but i realized that they don't have, to my knowledge, a 2003 update for this model. I came across a 750 update and i'm wondering if i should try to update the 740 with the 750 update. I've found out how to back up my stock Rom and operating system. But i'm wondering, if this 750 update crashes for whatever reason, i won't have enough access to restore the original rom system.
Anyways, those are my thoughts. please let me know anything you can think of.
