Now printer is in mode where it says “Firmware upgrade”. Then it said update failed, from memory it said 50% on printer. Ran the CLX6260FR_FD_ND_UpgradeJig.exe file, which automatically went into the “SyncThruWeb Service” logged in and update started. Downloaded update from Samsung cloud site ( ). Hi, wanted to get cloud printing working, needed to upgrade from V4.0.0.1.43 to CLX6260FR_V4.00.02.29. Operating System: Microsoft Windows 10 (64-bit) Samsung CLX-6260 stuck on Firmware Upgrade Thanks so much Thomas! You saved me and my friend and his patients because we wanted to use the fax in a hurry tonight. Thomas’ comment of gave a very helpful: “STOP (red) + Start (blue) at the same time and then switch on the printer on the main switch” and the printer LCD came back to normal again. HP doesn’t care if I want to use this Samsung machine and order more of their ink products (at least $400 worth) I began to look for many similar cases troubleshooting online. I first bought in US but brought to Europe so it’s not practical to send back. The trouble began when the idiot HP rep told me: your printer is out of warranty, if I pay for shipping it back to HP service center they would fix it. Two weeks ago I noticed the normal LCD only showed “SAMSUNG” blue logo instead of functional directory (fax, scan, copy, etc) so I called Samsung Technical services for printer – it was shockingly to know Samsung Printer division had been acquired by HP therefore all calls about Printer handled by HP people. Since purchased this printer a few years ago, I hardly use it any more than 500 pages.
