bootloader commands

---

write the gsm rom to your SD card.

d2s 60000000 400000

write the extended rom to sd card

d2s 70000000 1f20000

write the bootloader + os rom to sd card

d2s 80000000 2000000

the 6xxxxxxx and 7xxxxxxx memmory ranges are emulated by the
bootloader, no special memory mapping as I first thought.

write GSM ROM to SD

---

Hi ...
Could you please kindly explain how to 'actually' run the bootloader command?
I mean: do we run it from within the bootlader on the device? or do we have to connect the device to a PC through the cradle/ activesync or through a serial cable?
If must be run from the PC, what application (from Windows) do we need to install?

Thanks a lot in advance...

on a windows pc you need to connect the xda with a serial cable, and connect with some terminal program, like hyperterm, or securecrt.
or program connecting to \\.\WCEUSBSH001 your self, if you want to connect over usb.

under linux it should be no problem to connect your terminal program to the usb serial line.

put the xda in bootloader mode, by holding down the power button, and navigator button together, while resetting the device with the pen in the little hole on the bottom left.

you will lose all your date when you do this

Itsme: Many thanks...greatly appreciate your kind response.
Please allow to ask some more questions, I hope it's not too annoying
1. what's the name of the application for connecting thru USB? You mentioned "...program connecting to \\.\WCEUSBSH001 ..." sorry I need some guidance in this. Linux may be not an option for me as I have no accesss nor experience with one.
2. Is there any possibility for you to post the GSM ROM image (preferably for 900/1800)? Since we will loose data when doing this connecting application, I won't be able to ask some one to lend their working xda to do this. It would scare all them off.

THanks again for your kind help ....
Cheers...

you can use my xda2dmp app posted here earlier.
but as I said, under windows there are no apps that I know of that will allow you to connect to other serial ports than COM1 .. COMxxx

so serial over usb is only available to you if you program it yourself.

the gsm rom image is available in the upgrade, in radio.nbf

Hmmm... no hope for me... I have got no idea about programming communication stuff like that...

Thanks for the info about radio.nbf. I thought this one was only for XDA2 as it is filed under XDA2 title.
sorry if this may sound stupid, but is it possible to flash this radio.nbf from SD card using the XDA OSimage tool?

yes, radio.nbf is only xda-2

to avoid confusion, now I also set the xda-ii icon on this thread

GSM ROM for xda

---

could you please guide me to get a GSM ROM for xda?
my xda lost the GSM part since unsuccesful RSUpgrade (after upgrading to TMobile ROM 4.01.0, I accidentally chose the GSM1900 band in the phone- then the phone was not working, and then I tried to flash with an O2 RSUpgrade- but did not sucessful - resulting a total loss of the GSM part - the Radio stack and Protocol version were not shown during splash screen).

So far, I have been trying to fix the GSM using all kind of methods and using almost all sort of tools. No luck, always ended up at the RSUpgrade 1% Flash Failed screen.

I hope you could guide me a bit in this matter. Sorry , if I posted this question in this thread..

Willem,
Have you checked out FTDI? They provide a USB driver that can be driven as a virtual COM port. On the XDA side I can't provide any references.
