there you go mate.

 

bunzip that, then dd it to the USB drive if on Linux, BSD or OS X. Win32diskimager is a good option on Windows. 

 

That's the original 4.2.0 as-shipped, you'll have to upgrade it before it can be adopted.

Re: USG Recovery Procedure

Does anyone have info about the transfer rates of the USG-3s USB storage.

Or maybe a rough estimate how a replacement stick should be rated to perform well in the device?

Thanks alot!

Re: USG Recovery Procedure

Any USB stick will do. It's used only during boot, there are no writes to it other than config changes and firmware upgrades. All other writes, i.e. log files, are to ram disk.

Did this one work for others on the USG3? Want to make sure I have some other issue and not that I used the image wrong.

FWIW: It did appear to boot, just not well.

I have been trying multiple images but I still am having the same problem.  It powers on and just freezes after the DRAM: 512 MB

 

All I get is a solid green Console light (even with nothing connected). If I connect to the WAN, LAN or VOIP ports I get a blinking amber light showing a connection.  But those are the only lights.  No internal lights what so ever.
