firmware issue
yesterday was trying to update firmware (after making some tweaks) as usually via arduino and got verification error "first mismatch at byte 0x3c000 .
i figured that its a size issue .
printer was stuck with the squares on lcd...
i used slicer pe to upload original mk2 firmware and it worked .
then downloaded original mk2 firmware on github , compiled with arduino and get the same size issue error .
dont know whats going on , the source code files were working for me before , done many changes to the firmware before without issues .
also tryed to compile hex file and upload via slicer pe , same issue .
the file size (compiled) is 251074 bytes
file on prusa website is 241578 bytes
i dont know why theres a difference between the source code and the hex file on prusa website .
also dont know if somebody edited the source code , making it too large , or i have memory problem on my board .
can anybody help?

Hi Sergey,
Yep I have just replicated this problem. I couldn't get the firmware to compile with Arduino 1.6.13 so trying with 1.8.9 after deleting the platform.local.txt file I managed to get the code to compile but get the same error on upload. I'm trying to build from source as I have a volcano hot end fitted and need to change the max Z.
Looking for what I can strip out. If you find a solution please let me know.

I fixed the issue long time ago, sorry didnt check this thread for a while.
It was an issue with the arduino board. It needed an update in the ide. I updated libraries but didnt bother to update the board.
