Siemens SX66 ROM Update Issue

[hakushox]

I have a Siemens SX66 Cingular branded PPC. I downloaded the latest Official ROM Update but get the Wrong Country ID error. I found out that this was due my phone being an AT&T varient even though the phone says Cingular. So I wanted to know is anyone has the original ROM update that came out before the Siemens-1.33.10-Full_Update and if so could provide it to me thank you in advance. I need to put an offical rom back on my phone so I can send it back to cingular so they can send me a replacement phone.

Go to the SX66 Standardization Project (http://home.comcast.net/~sx66-blueangel/) to get the most recent ROMs for the SX66; they have both Cingular & ATT versions.

I went there but it's not an official version number which cingular will check for.

Try following the instructions here:
http://wiki.xda-developers.com/index.php?pagename=BA_FAQ_Upgrade_Errors

You will need to run the upgrade a second time for it to install, the first time clears the previous contents, the second time the upgrade should run.

Did you edit the .conf file as outlined in step 4? This worked for me. You may also try the MaUpgradeUt_noID route as well.

I prefer WM 2005 over 2003 I'm willing to work with the warts and try to advance the ball

Ya it gets rid of that error but then i get a error in the checksum

go back and make sure you have edited the editfix.bat file correctly, there is a set of three lines to recalculate the checksum and update it for each of the nba files (xda3nbftool -c -u ?????.nba).

hakushox,
The only way to get back to an officially supported ROM on the AT&T variant of the SX66 is with the MaUpgradeUt_noID. Now, I have not tried this, but here is what you'd need to do. Download the official Siemens update for the 1.33.10 System, and launch it. Once the first screen screen appears, open the Windows File Explorer, and search for nk.nbf. The one you are looking for will exist in a temp directory, and will exist with ms_.nbf, and radio_.nbf. Copy these files to a easy to find directory as these are the files you'll need to do the downgrade with. Cancel the offcial upgrade tool. Now, download the MaUpgradeUt_noID tools from this site, and extract it to a directory on your computer. Copy the .nbf files into that directory. Now, place your phone into boot loader mode, and place it in the cradle. Wait a few minutes for the OS to detect the "new" sync device. Finally launch the MaUpgradeUt_noID tool, and step through the screens. Once completed, it will place System 1.33.10, Radio 1.06.02, and Extended 1.33.110 ROMs on your device.

This works because the MaUpgradeUt_noID tool does check the ROM ids, and will let you flash any IDed rom onto your phone. As you can imagine, it is a rather dangerous tool if you don't have a good idea what you are doing, which is why I have tried to get it away from the Standardization project.

I tried uploading the original SX66 Cingular rom to the FTP but for some reason its not responding, if some one wants it email me and I will send it.

SysCrasher13 -

I am interested in downloading the factory Siemens SX66 firmware, after upgrading the firmware my SD slot no longer recognizes SD Memory... very strange.

Please let me know where to download the factory firmware.

Note: I have (2) SD PNY cards that work fine in my PPC4100, however, my SX66 doesn't recognize either card and wondering if this maybe a compatibility issue. I'm going to swap the 512MB with a SANdisk tomorrow to see if this rectifies the problem. Can anyone confirm SD compatibility issues with the SX66 --- is there a SD Memory quick reference chart available for the SX66?

Mike
