Subject: You can reflash the RSU on the SX56

--------------------------------------------------------------------------------

OK. This will have to be short and by memory but the good news is the details are all here in the forums. Thanks to everyone for the bits, I just stitched them together after spending hours of experimenting with my useless SX-56.

After using the PPC 2003 on my ATT SX-56 for a number of months I decided to dump it and go back to the PPC2002 version. I had problems with battery life, ring volumn, reception, dropped calls and some of my application would not work.

I was successful in using the ATT SX-56 upgrade on the Siemens site once. I did it a second time because I was unsure if some binaries got loaded (it appears that this image does not have the standard ActiveX controls which I got elsewhere).

During the second install everything went wrong. I was left with a dead PPC with no useful ROMS. Period. All I could get to load was the Wallaby 5.15 bootloader.

So this is what I did. Note only try this as a last resort before sending in your PPC PE to Siemens for a reflash as I was about to do. This may work for other carriers but you will need their versions of the files mentioned here.

ONLY DO THIS IF YOU ARE GOING TO THROW YOUR PPC AWAY

Brain Dead PPC with GSM Error and no ActiveSync

First you will need a SD reader/writer for your PC and and SD card. This first step will give you a somewhat usable ROM for the PPC side. We will deal with the GSM side in a bit.

First get hold of the Siemens PPC 2002 update and install it on your PC. (it will probably fail to your PPC since if you are reading this ActiveSync won't work, if it does you probaly don't need to read this thread)

It will probably hang on the warning screen. If it does just go to the task manager and end it. All you want at this point is the files anyway. They will be installed in Program Files\SX56 Upgrade utility

Get a clean SD card and copy the NK.nbf file from the english subdirectory to the card. Stick the card in your PPC SD slot and get the bootloader running. (soft reset + volumn button). It will load a new ROM into memory after you select the action (rocker switch at bottom of PPC).

After this you can softboot the PPC. It will probably ask to reformat the SD card. Let it do that as you don't need the NK file anymore and you will need a clean SD card.

PPC without Start Icon and no GSM

Now your PPC won't have a start icon and you will also not be able to use the pointer as the PPC will not have performed setup. Don't even try. All you can do is bring up the contacts and calendar to frustrate you.

Next we will get the repair.zip file (search for it in the forums). While it is made for the XDA we will use it only to give us back a functional PPC. Follow the instructions to copy the subdirectory and file to the SD card and reset the machine.

1% Problem

You will now find yourself at the famous 1% problem but you will have a Start icon again, which is a good thing.

Do not acknowledge the error by selecting OK. Let it be there but instead sneak behind and hit the start icon. Bring up the file manager and go to the windows/startup folder. Delete upgrade program. Do a softboot.

Working PDA but no Radio Stack

Now you will have PPC again but it will be slow and you will have no radio stack yet. Now to fix that. Go to your PC in the SX-56 upgrade/english directory and copy these four files to the Windows directory on your PPC.

monitor_ul_bs.m0, monitor_ul_bs.map, RSUpgrade.exe, RSUpgrade.cp64.

Once copied leaving your PPC in the charging cradle run RSUpgrade.exe from the PPC windows directory. It should upgrade all your ROMS and you should be back in business.

The only file I could not update was the rilgsm.dll. It was locked and would not let me mess with it or copy another on top of it. Perhaps another attempt at the upgrade program would fix this but I am gun shy right now and I have a working system again.
