upgrading without cradle

[padigelsa]

Is it possible upgrading Rom without Cradle, only with a serial cable?

Easiest way is using sd memory card.

Could you please explain me How can I do that? Or where I can see?
Thanks

though people seem to say that you should have charger power to the xda while you upgrade

Ok here you go, its a little outdated but its what I still use:
Qman's how to use XDArit to write nk.nb1 or nk.nbf to your SD card aka the Bootloader Method!
1. Place XDArit and the nk.nb1 or nk.nbf file in the same folder and start XDArit.
2. Select your SD card (disk drive) from the drop down menu.
3. Select Write to SD
Notice that the Windows CE box is already checked so just click the browse button at the end of that window.
4. Select your (nk.nb1 or nk.nbf) image and then Open
Notice by default XDArit will open looking for a *.nb1 file but if you're going to use a .nbf file you'll have to manually change the "Files of Type" to *.nbf
Notice that nk.nbo / nk.nbo was automatically added as your boot-loader and its check box is unchecked so leave it that way and click OK. XDArit should start writing to the card.
When XDArit has finished writing the image put the SD-card into the XDA and hold the power button and soft reset. You'll be taken to the below screen:

SD DOWNLOAD
Card Type:
CE OS & BOOT
Press action to Download
Or
Press REC to Exit
Press action to download and it will start the download/restore from the SD card.
Follow the on screen instructions once its "Completed" which will consist of a "Soft Boot/Reset".

is it ok to upgrade with the USB connection dangle thingy? ie straight from USB to the XDA2?

Yes it is ok to upgrade over usb, make sure you do it direct from usb port and not through a hub.
