Hi, I'm too stupid for the Firmware upgrade. For me it seems there are 2 different methods described.
in the description on the bottom with the KotomiApp i installed the driver, but when I plug in the PC connection (micro USB) the application says "no port Available" and after starting the firmware update it says "status: waiting for bootloader", "original FW version: unknown", "update to 1.79.0". But then nothingg happens.

in the decription on top i do not know what is the Left key. If I pull the weel key to the lefta and plug the PC USB connection (Micro USB) in the device says "Waiting for USB" and shows HW _ver 1.03 and SW_Ver. 1.79,  so it seems to have the latest Firmware anyhow.

So I think in the moment FW update is not required anyhow..
But I still would like to know how this should work .. maybe I need it in future..

For the first time to use the PC software, you should click "Driver->Install Driver" on the software, then the device is ready to be connected. Once the device is connected, click "Advanced->Firmware Update" will perform an update.

Also you can update the firmware without the PC software, find raw firmware file Kotomi Vx.xx.KotomiPremium on the website, and just drag the file into the U-disk popping up after bootloader mode entered (Key to the left and hold then plug-in micro port to the PC), wait for seconds and the meter will reset itself and it's done.

Ok, I've been down this road before...  You folks told me to do something, and bingo it worked...  But for the life of me, I can't find any notes, or instructions on what you had me do...

If I do the boot loader, and drag and drop the file in, I get "Upgrading....  134 > 134"  and it will sit there until the end of time...  I would try to do it through the Kotomi app, but can't get connected to device...   Help?

Try to install the driver on KotomiApp form and then see if it can be connected.

Or the other method, download the independent firmware "Kotomi Vx.xx.KotomiPremium" (DO NOT RENAME it) from the website and drag it into the u-disk in bootloader mode, do this in windows environment since some feedback says it might fail when this method is applied in MacOS.

Actually, I think some of my problems are cables...  Some of my cables are charging cables only, and will not pass data...    "Face palm moment..."

Again, Thanks...

When will I learn?   I should just leave well enough alone...   Using the correct USB cable this time....   I take the FW file and place it in the connected drive of the device...  I get the upgrading 134 > 134 message...   Never goes any ware from there...  After trying it a couple times now the SW_Ver: Unknown!!!   Have I totally bricked this thing now!  I can't get it to reload....

Quick update...   I uninstalled, and then reinstalled the latest drivers...  Then started the Kotomi app...  Version info showed the version in the app, but unknown on the device.  Even though there was a prompt of no port supported, I did the Firmware update from the app...  IT WORKED!  So its all up and working now...
