I own this old receiver and I would like to patch to fix WNRO. Firmware version installed : NAV Version : 4.83 2-SEP-93 SIG Version : 4.20 9-APR-90 Boot Version : 2.00 21-NOV-89 I have downloaded the 4.81 from http://beefchicken.com/gps/trimble/4000/firmware/ but seems there is a problem with the serial of the equipment. How to fix ? Is it any way to download my image to patch ? Thank You

Hi The 4000 is a *very* old device. It went past the “no longer supported” point back in the 90’s. Any of the updates would require a service contract that was in place for that update ( for the serial number of that device ). Any firmware that fixed roll over would now be into its second rollover ( = still a problem today). Even with an update, there are hardware issues with this era of device. Simply getting them to run is non-trivial. Last time I saw a 4000 it was < $100 ( delivered ) on eBay. That was a long while ago. The price was based on these things being an issue. No I have absolutely no idea what version FW mine has in it …. ( they are cheap , let’s see how they do ….). Simple answer: Run an external piece of software to correct the issue. It’s by far the simplest solution. ( no, it’s not trivial ….. ) Bob > On Oct 1, 2022, at 1:36 PM, marco bartoli via time-nuts <time-nuts@lists.febo.com> wrote: > > I own this old receiver and I would like to patch to fix WNRO. > Firmware version installed : > > NAV Version : 4.83 2-SEP-93 > SIG Version : 4.20 9-APR-90 > Boot Version : 2.00 21-NOV-89 > > I have downloaded the 4.81 from http://beefchicken.com/gps/trimble/4000/firmware/ > but seems there is a problem with the serial of the equipment. > > > > How to fix ? > > Is it any way to download my image to patch ? > > > Thank You > _______________________________________________ > time-nuts mailing list -- time-nuts@lists.febo.com > To unsubscribe send an email to time-nuts-leave@lists.febo.com
