HEy Stefan
,

I tried that but to no success. A quick dos box comes up but nothing happens. I keep my finger on the power/ on /off button and do a soft reset but all I get the the Window spocket PC 2002 screen.

Thanks for replying,

open a dos bos
Change to the directory, the xdatools are installed (may be progam files\XDAtools\binaries)
run the bootloaderfix.bat

This should work.....

I'm pretty much in the same boat. I've tried the steps you described and still can't fix the bootloader or access it. Help!

[cbr654]

I think the main issue here is the bootloader is writeprotected.

Again, when trying to fix the boot loader I get :


Unable to find Flash info offset, cannot disable bootloader writeprotect.

I have a serial cable that connect to the xda. Is ther anyway I can use hypertermina to fix this problem??

Thanks ALL

use bootloaderfix.zip
and read this

I tested it with 3.16.52, 4.00.10 and 3.04.00 ( the very old ppc2003 rom ).
It should also work with 3.17.03, 3.19.01, 4.00.01 and 4.00.05.

unpack the archive, from the command prompt, in the 'build' directory
run 'pnewbootloader bl515.nb0'.

it should take about 10 seconds.

output should be something like this:

C:\fix\build>pnewbootloader.exe bl515.nb0
protection found at 8c0d62d8
result: 00000000 00000000

i test it and work for me. now i have wallaby 5.15 already ....
...ps...i use winXp in run cmd to Dos mode of read this more

may be it's can help u

fist please read this fixbootloader.zip is work for .........

This tool depends on specific memory locations for certain roms.
It does verify that it is talking to a known rom. It also does a very
minimalisitc check if the file presented to it resembles a bootloader.

25.Now that's free times to Upgrade or Downgrade with no problem
26.in Wallaby 5.15 U must use Xdatool to burn rom in ur sd or mmc no need Xdarit anymore hehehehe ( very fast to write rom ..don't believe me? try with ur sef )
27.finish........and up to u to upgrade in wm2003 any version......... huray

May be this i write it's cannot help u so much .....but i trust may be it's useful for dump man like me to dowgrade Wallaby since i try to read more than 400 topic in here....... : )

and if u cannot flash 3.17.03 in sd because ur Wallaby block it....try to make rom is Nk.exe file but it's very risk to up/downgrade
by activesync because i broke my xda to dead because my com is Hank......... spare ur UPS to protect accident like me...

Hello All,
Need some help here. I am trying to unlock my SX56( AT&T). I am unable to get into bootloader mode. I held the power button and did a soft reset but it just resets to the Windows Mobile screen. AT&T phone signal suck and I am switching to T-Mobile but I need to unlock first.

Thanks !!!

This is a longshot but I suggest you try installing one of the XDA-Special Edition ROM's.
Read about it here: http://forum.xda-developers.com/viewtopic.php?t=1190

Or try using the Unlock tool stand-alone if you haven't already. Also try calling AT&T for an unlock code, hey it doesn't hurt to try!
Place the call and state "I'm switching carriers and would like to have my phone unlocked" and go from there!

BTW confirming your unit has been upgraded to Windows Mobile 2003 already, If so how was it done?
