Thanks for your time and valuable advice.

Usually then simply flashing original firmware via Updater.exe will restore rgn14 and the device will boot and function normally.
In my case, the Updater sees the device and when I press OK, it shows "Updating 100%" and I hear the voice disconnecting the device and the ID in the Updater program changes to 0 and after a while, I get an error like in the picture. Is it possible that this is physical damage?

(the picture is not mine, but it shows similar symptoms. in my case it shows the device and its ID)

Thank you again for sure I will read about it and I will try


And one more question. Let's say it is physical damage to the chip. If I find the same and exchanges it (I need the device) then I can later upload the software presented in the forum ways, or will I have to use programmers and upload something else so that the chip will be supported
