Hi,
Yes, it is possible to downgrade from bootloader 5.17 to 5.15 by using "Fix Broken Bootloader" program part of the XDAtools, as long as you have Activesync connection.

No, you must first write the wallaby patch tool to SD card (using 1k header), insert it, and put it into bootloader. The patch tool will then present its menu, and you can choose to read bootloader from SD (written with a 4k header), and then you're all set.
is there anyway to dump my Bootloader 5.15 into a file such that in case my bootloader crash, I can restore it back using XDAtools??
Hi,
Where can I obtain the Wallaby patch tool for bootloader v6.22?
I have Wallaby patch tool v1.2 for bootloader v5.17, but it is not effective for the new bootloader.
I have tried to download from http://www.xs4all.nl/~itsme/download/wbt-1.5.tar.gz but the file cannot be found.
Thanks.

I've never done it before but from what I heard XDAtool can be use to downgrade the boot loader. For more info. on XDAtools visit the Forum Index and look under ROM Upgrades for XDAtools.

Hi Adaoud,
I did successfully downgrade from 5.17 to 5.15 for the same reason you have using the "Fix broken bootloader" of the XDAtools.

I downgrade from 5.22 to 5.15 and upgrade 5.15 to 5.22 many times without problems!
Can you tell me how can i do this please?
Hi !,
I'm tryin upgrade ROM with Siemens+ATT A3.0.9 (pocket pc 2002 to WM2003).
Manage to burn it to SD (inside XDA) with XDATool.
Then do hard reset..but bootloader 6.22 just ignore the SD and not
give option to load the new ROM inside the SD.
I found an opinion : to downgrade the bootloader to 5.15...but I hope
to maintain the 6.22 bootloader unless it is really need to downgrade the bootloader. Furthermore I don't know to patch or downgrade the bootloader
Here is my device info :
ROM version 3.20.06 ENG
ROM date 07/30/03
Radio version 4.21.01
Protocol version 32S54
Bootloader 6.22
So what should i do ? hope for assistance from somebody.
Try using XDAtools to directly flash your ROM ... if worked it will update your boot loader to 5.15
Ok, the main problem is that I have bootloader 6.22 as well and foolishly have upgraged to the T-Mobile Rom.
Since then I have tried using the Kitchen to make a "B" type rom but to no avail.
Plus since this rom has been isnatlled it will no longer accept any different types of Rom other than that of a "B" type rom. I can't even use the pther "Programme A / B" to flash my rom
so in other words. I am stuck until I can find a way to change the header string on a rom. or to find a way to download a "B" type rom.
Please note. I tried putting a "B" Type rom in to the header string section of the kitchens and it cooked it... But still isn't recognised by my device.
