One more dumper for test. Can you please send me gupdate.gcd after testing?

[Only registered and activated users can see links. Click Here To Register...] you can find dumper-0.18 after it has been flashed. It takes 3 sec.

Can you also test this one?

when you say flashed do you mean written to the gl1800 nav ? Also how are you getting the dump after flashing ?
I have other reasons for playing with this and would like to learn all I can about it.
If I can help please let me know but also please be patient with me. I haven't done any of this in many many years.

I don't know what is gl1800 nav :) Please explain me :)
When I say "GCD file is flashed" I understand the following process:
1) GCD file is copied to some storage which the Garmin device can access (CF card, SD card, internal flash drive)
2) Somehow (details differ among different devices) boot.bin from the GCD file with matching HWID is executed on the device
3) boot.bin reads GCD file sections and writes them to the device's flash chip.
In this particular case boot.bin is patched and instead of reading GCD file sections it executes my code.

I will prepare something for testing, can you wait a little bit?
Edit:

Some new tests. Now I want to know if it's possible to change data of files other than gupdate.gcd (looks like this boot.bin can't extend files, it can only change bytes that already exist). I want you to copy new.bin or exst.bin to the root of the CF card and then flash the corresponding gupdate.gcd, and then send the .bin file to me.

May be I misunderstood your request? In the second try I didn't use any file of dumper-0.20. Only the #21
-
The request was the following:
1) make sure CF card is empty.
2) copy gupdate.gcd from dumper-0.20.rar to CF:/garmin/gupdate.gcd
3) copy new.bin from dumper-0.20.rar to CF:/new.bin
4) flash gupdate.gcd
5) send CF:/new.bin to me
And similarly with exst.bin and dumper-0.21.rar. Did you do it like this?
-
yes I did it, but I want to redo. See you in a hour, have a good dinner.

Thank you, but it's 21:25 on my clock already :)
In which folder does it create RGN0E.bin, RGN11.bin, RGN13.bin? CF:/ or CF:/garmin/?
