Thanks for your quick reply. I have tried to use the image from this Russian site but it did not work. I have also downloaded the program files for generating .freezestatus file but have no idea how to use them due to my lack of Ubuntu experiences. Fortunately my PB3 works with the original 4GB SD with read only status problem. I was able to extract the device info using your app as attached.
I would appreciate it very much, if you could give me an instruction for generating the .freezestatus file;

Where in Ubuntu should I place the program.
What are the command lines I should execute in the terminal.

I learned lots about Linux for the last 7 days. This was not easy for 70 year old man.
Thanks for your help in advance.
