restore Rigol DS1052D

[shurikstepanenko]

Hello. I really need help to restore Rigol DS1052D.
Broke my device with the wrong firmware.
I am looking for firmware (dump.bin) for Rigol DS1052D or Rigol DS1102D.
Perhaps someone downloaded from the device.
Today I managed to find the firmware for Rigol DS1052Е version 00.02.04 SP1, which I uploaded to the device and it started, but I cannot downgrade to 00.02.02 SP2 and try to rename the serial number to my own.
If anyone can help I will be very glad. Thank you.
