CRC Checksum Failed Message after Firmware Update

[BestRadarDetectors]

If you receive this message after the latest firmware update there is nothing wrong with your system or the firmware update. The latest firmware will check to make sure you are using a new Configuration file and will display this error if you are not running a current configuration file. You will need to run a Factory Reset which will clear your existing settings and load the default settings file. If you are only running Laser this will default LID settings to 4 seconds and bring you back into Defense settings until you get a chance to load a new Config.alp file, If you are running Radar you will need to immediately load a new file with your Radar settings because there is no default for Radar.

If you have a new config file ready when you do the firmware update, you don't need to do the factory defaults. Just load the config and you'll be good to go.

I did mine with a USB that had both the firmware and a new config.alp. The firmware loaded, I got the checksum error, then Data Stored, and everything was fine.

Hi radargeek, When I went to load the new Control Box firmware 5.2.5/6.8 last night (Uxxxxxxx.bin), I also had the three additional, newly generated, files on my USB flash drive. (UCSTHIFI.BIN, VOICEPCK.ALP, CONFIG.ALP). A few seconds after receiving the CHECKSUM FAILED verbal warning, I received DATA STORED. But I was not sure if all of the downloads were really complete, or if there was some type of an error in the download process. That is why I stopped, and asked questions on this Forum, before proceeding to perform a RESTORE DEFAULTS AND MEMORIZE SENSORS, then try the complete download again. The system gave me a DATA STORED within a couple of seconds after I inserted the USB flash drive, and everything on the PRINT USE STATISTICS AND DEVICE INFORMATION checked out to be identical to each of the three Configuration Profiles A/B/C.

You were fine.. There was nothing wrong with the firmware update and trying to install firmware again would just be ignored since you cant install new firmware if the installed version is the same or newer than what you are trying to load.

Hi Tom/BRD, No problem, but I am just wondering/curious as to exactly what caused the CHECKSUM FAILED to occur? Will we have to perform a Restore Defaults and Memorize Sensors during future Control Box updates?

I had previously performed a Restore Defaults and Memorize Sensors, when it was mandatory to do so a couple of updates back. When I performed the Restore Defaults and Memorize Sensors late last night, the Configuration Settings reverted back to the Default settings, as they are supposed to do. When I went to download all four files again, the only file that was actually loaded was, most likely, my Configuration with the 3 Profiles A/B/C, as I did hear a Data Stored message a few seconds after inserting the USB flash drive into the system's USB port, for the second time.

We changed the settings file with the addition of the Net Radar and additional future additions and the check failed when the ALP checked the installed configuration file to see if it was the right format. The Error clearly tells you this and it does not say that the firmware failed only that there was a CRC Checksum error (Because old config file is loaded) and tells you to run a Factory Reset to load a new default Configuration file or you can load a new custom Configuration file with your updated settings.

Anytime I install any new firmware I automatically just make a config file and put that on my USB stick and load them both at the same time--eliminates the headaches

Hi Holla, When I install a new firmware update, I [U]always[U] also load the other three files, just in case there is something that changed within any of the files. When I heard the CHECKSUM FAILED warning, that I had never heard before, nor have I ever read about anyone ever receiving such a warning, I did nothing else until Tom/BRD advised me to just perform the RESTORE DEFAULTS AND MEMORIZE SENSORS function, then load everything again, which was successful. All functions appear to be performing normally.

Perhaps a future voice pack update could change that message to something like "Configuration Checksum Bad, Restore Defaults" so it's clear it's the configuration and not the firmware that has the bad checksum. Or to make it clearer for non-techies, "Configuration is invalid, Restore Defaults."

CRC stands for Cyclic Redundancy Check, which is just an algorithm for generating checksums.

I just remembered that my dashcam was recording when I did my update, so I pulled the footage, so you can hear what it sounds like. In my case, I had a new config.alp already on the USB, so immediately after the "Checksum Failed" it loaded the new config and said "Data Stored" and everything was set back the way I wanted.

We higher professional artists for our voices and it makes no sense to pay for a recording session for only a few new terms. When we get several new terms that we need to get recorded we do a session for them and put out a new voice pack.
