After OS Update Jum Error 545 and no manual OS update possible

[sebotnic]

Hey everyone,

While doing an OS update on my curve 8900 to vers 5.xx during the installation it appeared the error message Jum Error 545. So far i already read all topics about this error message. i tryed to do an OS reinstall. i wiped the phone and tried to install (already two different OS versions) after the wipe. i tried it through loader.exe and also used bbsak. i can start the OS reinstall but it never goes any further than the uploading RAM screen. if i am rebooting the phone its not even passing the boot screen and stops while 2/3 of the loading screen task. jum error 545 again and again. tried many hard resets, wipes and again os installations through loader.exe....always the same.

do you now any other solutions to kill the whole phone, and do a proper new installation of the os? any solutions would be welcome. and thank you at all...
