as far as i know the memory is divided in 3 parts.

ab) 64 megs of ram ( main memory) this is divided between storage and ram.
Some of the OS files are stored here.

c) built in storage 32mb
I personally think its useless as soon as u get an SD card

d) rom: the rom image is stored here.
this is accessed when the pda hard resets to restore the os. i think it also installs some of the OS files are stored here.

SP_E0402_230A.nb0 is 256k (bootsstrap)
SP_K1112_230A.nb0 is 29mb (rom image)

now both files are needed for the PDA to function. now playing with the boot strap is dangerous because if anything goes wrong u will have a paper weight or a door stopper.

Yes when u do write the rom image that was posted here it will lock your phone. They would only give me the updated rom image which has a lock to at&t. that can be easily solved with the replacement of the rilgsm.dll file and that’s not a problem.

now. if I understand xjxaver correctly u have flashed your pda with the audiovox 4100 and it works but it doesn’t allow u to use the phone because its locked? Or because of another reason?
If its locked u can grabthe rilgsm on this site and replace it then soft reset that’s all u will have to do. Let us know how things go.
Did u also write the bootstrap or just the rom?


nemo3, go here http://www.xs4all.nl/~itsme/projects/xda/romtools.html u will find really good info on where the directory structure is located and other.

The file formats we are talking about her eare for the xda. This one seems to be a little different for some reason. Xda uses nb0 format for the bootstrap only. Nb1: the rom image only. And the nbf should have both rom image and bootstrap.
This is also explained on the link provided above.

if I am off please correct me.
