Hello Przemek,

after downloading, you'll have load the firmware onto the device; that usually happens automatically after a power cycle. Did you remove the USRP from power before trying to use it again? I'm asking because I don't see the FPGA loading sequence in your output.

Regarding the version mismatch: that should be ok, UHD 3.10. uses the 3.9 image compatibility.

Best regards,

My situation is:
I had previously version of GnuRadio from June. Everything worked fine. Today I need to update my software due to patch for multiply_matrix_cc, and I had small problem with Pybomb due to Python Miko that wasnt exist. Ok I installed it. But befor that I searched solution and uninstalled nearly everything. And after that I had installed newest version of GNURadio from repository and newest version of UHD. Now everything is nearly working, buuuut when I want to send my old files to B210 I have this error:

And yes, I run python script 3 times, and it replaced images properly.... Information should be somewhere else about firmware. OR I have   UHD_003.010  and python scipt downloaded wrong version :) here is the output from python script:

Thank You for any advice :)
