Downgrade to 2002?

[zaeng]

Hi, I m 1 of the fools, who tried to make a upgrade for my t-online MDA from WIndows 2002 to 2003 - but until now using O2.

After the update the mda does not start anymore. It shows only the startup screen with this data: G32S54, R3.23.11, 4.01.19 - but only with the o2-SIM. Otherwise nothing.

Hope, I could get a little help..

Thanks a lot..

You need to download the rom you require from the kitchen in nbf format, you then need xdatools, using xdatools you then program an sd memory card of 64 meg or greater with the nbf file, place the memory card in xda, push reset with stylus while holding powr button. Push action buton when prompted. Make sure your xda is charged. You should end up with a working system.


One question, did you carry out a hard reset after flashing the rom? This is done by unscrewing the stylus and using the top half to push in the tiny hole on bottom left of your xda, push once, wait one minute, push once more.

I´m very sorry (or silly..), but what or where is a kitchen?

I made a hardware reset. The only thing, that i could get, is the wallaby bootloader 5.22 with the announcement GSM OK.

a kitchen is where you make your own rom

Hi, fine - but could you hold my hand one more time...

I now have an MultiMediaCard with a file NK.nb1. I start the boot lader, it reports "GSM ok" - thats all. Must I initiate the MMC or do something else?

did you follow this guide ?
because you cant just copy the nbf file to the sd card

Ok here you go, its a little outdated but its what I still use: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".

Thanks. It works great. Good stuff you made.

The problem was, that the osImage Tool did not find the SDCard correctly, only after a programm restart. Now its working fine.

I will try to upgrade again, proofing wether 02 can work on an updated T-Mobile MDA I.

Thanx a lot.

Also: als Resümee:

Upgrade möglich, O2-Verbindung problemlos.


For interest:

Its no problem to Upgrade MDA I from T-Mobile to Windows CE 2003 - also if you want to use O2.
