I want to have another go at getting my recalcitrant Cores working properly after several abortive attempts (I get fed up and leave them sat doing nothing for months at a time!) Before I start, to maximise my chances of success and minimising sadness, is there a convenient way to check each Core is on the most recent everything (firmware,bootloader etc etc) ? thank you ---

The most recent CLI should give you most info via ```nohighlight particle serial inspect ``` ---

Thanks - might I run that and report back or should it be relatively easy to then compare with online documentation? What I found confusing before was that all my various firmware/bootloaders were out of date but nothing but the helpful people on this forum prompted me to update anything. šŸ™‚ ---

.1. So I tried to use the most recent CLI and got this > C:\Users\Office\>particle serial inspect > Serial err: Error: Opening COM3: Access denied > Serial problems, please reconnect the device. > **!** serial: Serial problems, please reconnect the device. I should mention that running "particle doctor" seems to work. .2. I tried to download and run the firmware manager and get a kivy fatal error due to my opengl version. .3. I tried to flash my Core from the web GUI build and "flash is unsuccessful". This is what I remember about Particle and why the last heard from date on all of my Cores was June 2016. ā˜¹ (!) Thanks for your help ScruffyR ---

OK after running Zadig and running the Particle Doctor twice and then putting the device into listening mode I was able to obtain the following info (see pic) ( ![](https://us1.discourse-cdn.com/flex026/uploads/particle/original/3X/a/b/ab14cbc43b1e0057326cc67db9ccfdcee1e2201d.PNG)The web console says firmware unknown.) ---

Just tried to flash some code to the Core via the web GUI. This now works (following running Particle Doctor twice) but it doesnā€™t seem to have updated the firmware at all. ---

The Core uses a monolithic build. Thereā€™s no system firmware to update. What you build on the IDE, is whatā€™s getting flashed. ---

Thanks Moors7, I understood (perhaps wrongly) that some of the underlying chips etc had their own firmware which could be updated/upgraded to improve WiFi reliability etc. My Cores drop WiFi connections all the time. ---

> [@daneboomer](#): > > some of the underlying chips The only one I'm aware of is the CC3000 WiFi module. This gets updated via ```plaintext particle flash --usb CC3000 ``` But the CC3000 is also known to be a bit unreliable and suffering from amnesia. So the best option IMO - although I also hate early obsolescence - is to move on to the Photon. I've got several Cores but am not using one of them anymore. ---

@daneboomer, TIā€™s last ā€œworkingā€ CC3000 firmware is what is flashed over when you run `particle flash --usb CC3000`. They no longer support this device. After flashing that code, you should do a `particle flash --usb tinker` which will download tinker to your Core with v0.6.4 system firmware most likely. Then you can confirm if your Core is working properly and flash over any new app/system firmware as you desire (since they are combined into a single file for flashing). The CC3000 was a first from TI in a generation of WiFi chips. It used an 8051 MPU and not lot of flash so TI was very limited in getting a lot of code in there, especially when bugs cropped up. And as @ScruffR pointed out, it was prone to amnesia and just plain failure. This was one key driver for moving to a Broadcom platform for the Photon. šŸ˜‰ ---

Thanks @peekay123. > [@Moors7](#): > > The Core uses a monolithic build. There's no system firmware to update. What you build on the IDE, is what's getting flashed. @Moors7 Just been reading back through my old messages ...isn't there a "_deep update_" I need to flash each of my Cores with? I will try to do that tonight. ---

@daneboomer, I believe using CC3000 provides the deep update.
