How to fix failure during upgrading ROM

[Seif]

I have a siemens sx56 with AT&T. I was trying to upgrade the ROM version to unlock it. Using XDA developer software and during this process, somehow the connection between the computer and the phone stopped (active Sync). Now the phone is not responding and the screen still displaying the upgrading process. I tried to reconnect but the Active sync does not recognize the devise. I read in this forum that you can solve this problem by using SD card with a good ROM version. Here is what I did. I copied the NK.nbf to the SD card using my computer SD read/write slot. I inserted the SD card in the phone and did the boot loader mode. What I got is "Wallaby boot loader v5.22 GSM OK" that set. Does the phone will automatically ask to press action to start flashing or I have to press a certain key. I tryed all the keys but they give me different tests that they work fine. So far I am not able to find the key that will install the the cooked rom. After that, when I tried to use the SD card in the computer, it did not recognize the card and ask me to format the SD card. I tried the fat and the fat 32 format and download NK.nb1 and/or NK.nbf and again I got the samething. Do I need to down load the ROM file using the XDAtool or just copying the file from the computer to sd directory will do it. I would really appreciate it if someone points out the best way of handling this problem (i.e. get the phone to work with the appropriate ROM and unlocking it) thanks.

Bro, you shouldn't change the Sd fat you erased what's written on it anyway your unit is still on the safe side and you can bring it to normal.

First of all downgrade your bootloader to 5.15 >>>

Hi,

I also have exactly the same problem with my Siemens SX56 as those of Seif's. My Wallaby's boot loader version is 5.22. Ramram said that the first thing to do is to downgrage bootloader. But I couldn't understand how to downgrade the bootloader because I do not have a copy of old bootloader. Should I use 'OSImageTools' or 'XDArit' to write backed up CE image to SD card?

Seif, how did you solve your problem?

Best Regards

You need XDArit to write the rom to your SD read the past post on how to copy rom to your SD which is the safest way of installing the rom into the device, by using XDAtools press on FIX BROKEN BOOTLOADER this will downgrade you bootloader to 5.15 don't forget to connect your unit to the cradle when you want to downgrade.

I recommend 1rst of all to make a quick search in threads to be totaly ready for this :)

Good Luck now.

The problem was solved. Here is what I did. I copied the NK.nbf file to the SD card using the XDAtools. It seems that the XDAtools uses special format for the bootloader that well recognize the ROM file on the SD card. Rafia your bootloader (v5.22) is fine you do not need to downgrade it.
You should follow this procedure:
1. Install ActiveSync that comes with the device.
2. download XDAtools from this site and install it in your computer.
3. Cook the ROM ( or get it by extracting the zip file from the XDA developers special edition ROM.)
4. Use the XDAtools to copy the cooked NK.nbf file from your computer to the directory of the SD card
5. Insert the SD card in the dead device and go to the bootloader mode (soft reset while pressing power key). Make sure it has more than 80% battery before starting.
6. If it is still working and the bootloader ver. is older than 6.22, it will ask you to press action to start flasing.
7. Once finished, remove the SD card and hard reset, wait 60 sec and hard reset again.

Good Luck and special thanks to Biso for his help.

Thanks a MILLION for this info. I'm in the same boat, with bootloader 5.22. One question though, when I'm in bootloader mode, which option do I choose from the menu to transfer the ROM to my device from the SD card? Will there be something automatically coming up? Or will I use one of the options listed below:

1. CE ROM TO SD
2. BOOT TO SD
3. CE + BOOT TO SD
4. GSM ROM TO SD
5. CE + GSM TO SD

By the way, so I never do anything to ruin my device again, can someone please explain what each option does?? I really don't have a clue.

as you can read from the menu you type in all these options are to the SD card

and they are to backup i suppose

rom upgrading should start automatic when a sd card with valid rom is in the sdport
and you are in the bootloader

maybe it ask you i forget but it's not something you have to find browsing
the menu's

Thanks for answering my question. Now I simply need to find a really good ROM to use to load back onto my device. What I would like to do is end up with Windows Mobile 2003, but the device is locked at the moment.

Can someone recommend a ROM for me to load onto the device so that I can then unlock it and THEN upgrade to 2003? Or is there a 2003 ROM out there that will also unlock? Originally, I ended up in this predicament by upgrading to the 2003 upgrade from Rogers AT&T, but that locked the device on me. I then tried to use a cooked 2003 ROM, and that's where I am now, without a useable device.

Thanks for all replies!

First of all get the "Special Edition Rom" to your device Unlock it then cook any other Rom you prefer
Special Edition Rom at http://cuba.calyx.nl/~jsummers/XDA/XDA-developers-SER-v12.exe

Good luck

Thanks, Ramram. I'm sure I'll have more success this time, but it's just odd that I went from a 2002 ROM, which was unlocked, to the Rogers 2003 ROM, and the phone was locked after that.

I guess I should stay away from that Rogers ROM then?

Why to worry about the Rogers Rom you know now a way to unlock your phone.
I assume the Rogers rom is based like the At&t rom which it has the sound clipping bug , so I'd rather say that you could cook a T-mobile rom 4.01.16 WM2003 and try it :) it does not have the sound clipping bug..
