Built-in update rom utility in 8390

[Guest diudiudiudiu]

no luck at google

taiwan mio tech support and my local tech support don't wanna tell me until they die

just did a quick ssearch at that taiwan forum

mobile-life and found the way to trigger this utility:

hold down your down button when u power on your phone

haven't tried it myself but it seems that you can backup/whatever your rom just like the way u do it on other pda/smartphone.

WARNING:Don't mess with anything inside if you don't exactly know what you are doing,you can always choose no.5 and reboot safely

ps. oh take a look again the dump feature is missing, stupid me:E
