Extract fat image from flashrom/filesystem

[hanturaya]

Hello again,

Try #1 with YFormat only:
"Found Format File, Size is 12"
Erase: .................
Ok
---> partitioning step DID NOT come up at all...
---> straight away display startup photo and hangs...

Try #2 with 3 files:
"Found Bootloader File, Size Is 32,768"
---> display hangs on that screen...
---> same after waited for 30 minutes...

Try #3 with OS82C + YFAPP only:
"Found OS File, Size Is 34,458,684"
Read: .......................
---> Hangs after 100% read...
---> same after waited for 30 minutes...

Regards,

Obviously it doesn't reflash bootloader and is refusing to create/reflash shell (menu) file.

I found this thread

Until now all your trials were based on OS file recovered from your friend's device; as a last resort, you could download the 2 packages from there and try them.

[hanturaya]

Tried that before... didn't work....
Now, where's that screwdriver....

[ablbd]

After looking into bootloader I didn't expected that v2 would work.
What it worryes me is that it's not reflashing bootloader, yours may have been slightly corrupted...

Maybe you should try with following files in sd root: yformat, os82c, bltd82c, yfaap and yfupdate. Create on the same sd a directory called "ResidentFlash2" and put there the files I uploaded earlier, actually 2 directoryes with files inside.
Try simple hard reset and/or combined soft reset pressed while hard reset...

BTW, you could try also this package http://www.megaupload.com/?d=4WTG2KCW
It is rom version 11.3, one of the newest for this type of devices and probably the last one (they switched to CE6)... You won't find it elsewhere on the net cause it came several month ago on a private "channel" directly from China.

Hi again,

Tried all options... the hammer is out... the YF82c misery ended...

Thanks so much for the guidance and help... although it did not solve my problem, maybe there are others who benefited from the process...

Hi
Returning to DiskRW subject, I sadly announce that this excellent tool will NOT work on CE6. At least not without modifications...

After a short glance in it's dissasembly, I will enumerate some of the reasons:
-CE6 is not supporting SetKmode API; only few dll's from OS can run in kernel mode, all other are running in user mode
-CE6 has a completely different memory layout which is not allowing one process to access other's process' or kernel's memory; this means that SetPermission(0xFFFFFFFF) API will not work (and is not supported by coredll)

Besides that, programs using following API's will not work too:
-KernelIoControl: protected API which cannot be called from user mode
-fastcalls and function calls using GetProcAddress: direct memory access is forbidden

It's not an exhaustive enumeration just a hint why ce4...ce5 programs will not work in ce6

Hi ablbd,
I haven't been here for awhile.
What is the reason, the ce5 programs don't work on ce4?

[ablbd]

What is the reason, the ce5 programs don't work on ce4?

There is no particular reason as for CE6. Is only question of dependencies and/or some coredll functions which are called by the program and may not be present in certain devices. Pick up from ce5 all dependencies + coredll and copy them into same directory where your application is started from (...or cook the rom of that particular device with a ce5 coredll ).

Keep in mind that dumped dll's will work in ram only if they were included in rom as FILES, so look after dependecies in packages/patches where dll's are relocated.

After following various threads on various forums, I had a go at extracting a firmware from my Navigo v2, CE5 based GPS
It all looks fine and installs (more or less) but binmod fails (doesn't find TOC)

Anyway, ablbd (or ojejoe) any chance you could use your tool to extract the bin files for us? or perhaps share the tool??

Don't give up hanturaya. Please see my post here http://www.dealextreme.com/forums/Forum ... did.593550 and try my uploaded firmware here http://www.megaupload.com/?d=WOMA1UJ4.

My GPS PNA is from Masada, I think yours is the same.

I would but whole day megaupload replied with "The file you are trying to access is temporarily unavailable"... and I'm accessing it from a premium account.

That program is an experimental one, far from being released.

Copy files from \boot into the root of an sd, let's hope that is going to work. If not, I will need additional RAM dumps to figure out what the bootloader is expecting.

Hi.

I am new here and will start with the problem I have:

I have an image of a ROM which is in .bin format.
So now I would like to make it flashable as I have the same problem as ojeoje described on page 2:
Only NK.bin, TinyNK.bin, ... are accepted by my device.

Can somebody help me with a kind of HowTo to split it up accordingly?
I do understand I have to look for ECEC in ROM which I did. 7 times in total.
How do I find the end of the sections and what section is what file (NK, ...)?

Any help appreciated.

[ablbd]

I've seen upgrades which are combining all those parts in one bin but in that case usually it has also a "special" name. Upload the .bin to look what is all about.
