Hello German folks :-)

Thank You for helping me. It seem that I have all the tools and files that I need now. I used Google translator to translate CTHTC's summary, how to change RM-1105 to RM-1104 and it looks like this:

01. Connect the phone to the computer using a USB cable
02. Download and unpack the AT & T_RM1104_RM1105_Softwarepack. To do this, create the "Test" folder in the C: drive. Save the software pack in this folder and double-click it. The software pack is self-extracting.
03. Install the Windows Device Recovery Tool (part of the AT & T_RM1104_RM1105_Softwarepack in folder 006)
04. In the shell (command line), press the Windows key and enter CMD in the window that opens, and then press Enter
05. Enter the following command: cd c:\program files (x86)\microsoft care suite\windows device recovery tool
06. Enter the following command: thor2 -mode uefiflash -ffufile "C:\Test\001" -do_full_nvi_update -do_factory_reset

Note: It may happen that thor2 collapses during this process. In this case just wait until the phone has rebooted and re-run the process.

07. Wait until the transfer and flash operation has been performed. The course is comprehensible on the PC
08. Enter the following command: thor2 -mode rnd -bootnormalmode
09. In the shell, type the following command: cd c:\Test\002 This will take you to the folder where the iuTool is stored.
10. In the shell, type the following command: iutool -p C:\Test\003 -V

Note: If error 0x80070490 appears, then remove the phone in the device overview and repeat point 10.

The data is now transferred to the phone. The following information should be displayed on the computer:
[1] Started device ** individual numbers - combination **
[1] Transferring files started
[1] Transferred file 1/3
[1] Transferred file 2/3
[1] Transferred file 3/3
[1] Transferring files complete: 3 files
[1] Update started
[1] Installation failed (HRESULT = 0x8024a110)
[1] Failed (0x8024a110)

ERROR: 0x8024a110

Note: The error message can be ignored because the platform ID is changed here.

11. The phone restarts, the update is installed.
12. Enter the following command: cd c:\program files (x86)\microsoft care suite\windows device recovery tool
13. Enter the following command: thor2 -mode uefiflash -ffufile "C:\Test\004" -do_full_nvi_update -do_factory_reset
14. Enter the following command: thor2 -mode uefiflash -ffufile "C:\Test\005" -do_full_nvi_update -do_factory_reset
15. Enter the following command: thor2 -mode uefiflash -ffufile "RM1104_neu.ffu" -productcodeupdate 059X4V9 -skip_flash

Everything seems to be clear, but I don't understand point 15. I haven't found anything like RM11047_neu.ffu file. Is it being created during the process? Or is it just some kind of fake file to change device to 059X4V9? It also seems, that there is missing one quotation mark in the original description of point 15, so I've added one.
Are all the commands right? I'm asking, because google translator sometimes messes commands, so I tried to take them from the original german description.

I will start with change of RM-1105 to RM-1104 this evening, when I have more free time :-)

Best regards
Martin
