3330 dual 3315 MENU: is this possible?

[theremoids]

just a weird idea...

if we convert a 3330 to 3315, we flash two 3315 flash file...
one at 200000 and the other at 400000.

is it possible to have a MENU in the fone and choose between the two flash files?
so we can have two different versions of 3315?

So far... Nope

And your idea is wierd, yes...

I think you're on your own on this one, but hell... why not try to do some research yourself?
It ain't as difficult as you think... everything is set up in a logical way, just that it is very hard to see it sometimes.


Do some research on assembly and how the firmware works and you'll figure it in the end (though you will most likely have a new phone a long time ago when you have figured it )

Best of luck

well... i think it's possible and i did a thorough research before i posted this here... for your information.

thanks tho you're not much of a help.

Hypothetically speaking it could be possible, but there is one big problem: from what I know the flash execution starts at 200040. So to switch to the other flash you'll have to make the phone start at 400040 instead. This could be done if the first flash is modified to jump to the second address somehow (maybe after reading something from eeprom) after it's reset.
Then the second flash would need to be modified because it has hardcoded values of 200000 and 300000 and the values are at 400000 and 500000.
If the hardware is the same this could work, but I wouldn't bet on it

Best regards,

what does phone ram contain?
could there be made a menu?
000000-200000

First of all... it's gonna be a hell of a project...

Remember that you have to tell the phone at boot-up what version to choose. And as far as I know, there are no bootloaders for phones YET.

But if you know someone good at programming and knows a lot about nokia phones to make a boot loader for it, then give it a shot.
But remember that you're gonna get a space problem in that case, but technically you can remove some ringtones and other crap to save some space.

Anyway... this is probably gonna stay as a idea only.
I don't think too many needs this option, so there won't be enough research on it.


Good luck

the converted "3330>3315" reads the 400000 not the 200000.
that's why if you want to have a modified "3330>3315"... you have to flash the modified 3315 at 400000.

now, what i want to know is how we could "boot" the fone at 200000?

[milango]

for dual booting;

First, Install the windows 98
Second, Install windows 2000

Thats very easy huh!
Your celpon now will have two OS

Hehehe

Noone to take the job to make a dualboot for you yet?
Would be really fun to see sth like that happen though, but I doubt it...

you've got ur creativity on the work, its nice to hear some ideas not coming from my ownself. i'm not that genius on this but i think its easier to other forum Veterans like Nokdoc, G3, Joxx and others than creating all their patcher programs before coz this is just mapping the 2nd flash to its new location triggered by a bridging menu.

in my theory:
replace line 2 graphic or something else with a call to 0x00400040
when you bring that graphic up (hold * button), software will jump to the mirrored section of flash and continue as normal.
personally i cant be bothered to test this
