Thread: Table of nuvis PCB P/N written in FW and possible conversions

Thanks for that Loly. Nice program too, as is HxD recommend by kanopus. I've now tried the 310 file from Caty in several different hex editors/viewers and the result is always the same. Where the PCB PNs should be i get this:

. . flush_map> flushing %u map pages, lock %u, gen %u to page %u, sver %u ? Ì *s 575-

and obviously i should see something like this:

? . \ . * . . . . . s . . . 105-00968-00.105-00968-S0.105-XXXXX-XX

I'm using Win 8 but i've also tried it on a different PC running Win 7 with same result. Here's the file in XVI32 and Portable UltraEdit32 compared to Caty's HexCmp:



In post #38 there is a screenshot of my original file open in HexCmp as well.

The views above are of the same file uploaded to ZippyShare by Caty and the MD5 is B779E001286E0CF7B04248CAC57B0CD2 which matches my original file in any case. Do you mind checking the hash on your original file please Caty?

Can anyone explain how can there be differences in it's content when the same file is viewed in the same programs?

@Neil
In post #42, the first and second screenshots are from the same file (nuvi310...), but the third screenshot is from a different file (nuvi300...). I don't expect to see the same search results. Am I missing something?

@syzygy
No, it's me missing something [between the ears!], and i'm blind coz you're right i've got the wrong file shown. Actually, my eyesight is really cr*p so i'll use that excuse rather than the lack of brains one. Thanks for picking that up [the file error, i mean .... oh, and the brains thing too then....]

The whole point of my ramblings is because of my unsuccessful attempts to find the PCB PN's in the fw's of 310 [hwid 0566] and 610 [hwid 0569]. The string 58 42 4C 4B 53 [XBLKS] appears twice in 310 and once in 610, but unlike with another related fw [300 hwid 0476], a XBLKS entry isn't followed closely by the PCB PN/s, and searching for 31 30 35 2D [105-] of course yields nothing either. In another, 310MLC [HWID 0856] i can't find XBLKS or 105-. However, a search of 105- in 300MLC [hwid 0855] finds the PCB PN 105-00968-M0.

So is it that these 310 & 610 fw's don't have the PCB PN's written into them or is it just not possible to find them by search?

You're right i guess. It's just not written in fw. But if it's also not shown in the 'battery menu' that doesn't make it very easy to retrieve. My 300 has it in fw, but it's not in the 'clock menu' [you have to hold it for several seconds instead].

Thanks to everyone for the interest and help. At least i've honed my meager hex editor skills a tiny bit.

Anybody try to convert nuvi 140 to 2xx5?

I want to add
Nuvi 2699 (hwid 1948)
105 02458 00

And I saw here somewhere possible conversion to a Camper 660 or 670...

Edit:

I just done converting to a Camper 660

First I try with hybrid method 1 (mismatch)

Second method (full conversion) was successful.
