ppc2002 to WM2003

---

Hi.
I have a XDA1 running on PPC2002. If I upgrade the rom to WM2003, do I have to do any extra steps before executing the cooked rom from the kitchen in the pc?
Another question is that can we revert back to ppc2002 after upgrading to WM2003 ?

My bootloader is of ver. 5.17

I'm from Singapore.

Thanks.

The EXE method might not work with bootloader 5.17 ... but give it a try ... or you can go directly to the SD method

For going back to PPC2002, just cook another ROM and put it back using the same way.

Good luck

I use one sd card to backup current rom using bootloader then ce to sd command, I then use another sd card to flash the new rom, that wa you can always revert to your original rom.

Thanks.

So, its pretty safe to switch rom from ppc2002 to wm2003 and back to ppc2002.

BTW, for those XDA1 users, who had upgraded to WM2003, do you encounter any problem arising from the upgrade?

Thanks.

Cooked a WM2003 rom from the kitchen and upgrade through the XDATool method. The upgrade is successful.

However, the phone HARD reset when I browsed through the BAND switching option, without switching the band. Is this normal?

Thanks.
