So when you do a x6100 firmware upgrade, the radio starts and a screen dialog tells you what's happening and automatically shuts down.? So at this point what has been written to where ?.? Then you take the sd card out and re-start.? At this re-start what is written to where ?

Thanks

It should have written? to the flash memory in the STM32. It does say Erasing Flash when you see the process working ?.? Think there are some You Tube videos that show this.?

The APP firmware the one that you see erasing and loading. There is no visual feedback on the Base upgrade which occurs after system/upgrade button pushed (except a perecentage).

That's right you don't? get much confirmation of what's going on.

Has the radio ever been apart. And you are doing the fw upgrade with external psu,say 13.8v connected. Are you happy enough? to take the radio apart.

Hi Keith. Yes, external power. Warming up to taking it apart, watched a few repair videos so know what to expect.

Simon??

Watch out for those balls !? re the leg that is ....mine does not have any so going to order, size is 2.38mm.

Now? Possibly the best firmware/base version thread ?Joao, CT2HME?? the screen shot of the firmware he has stored.

Is there any help in that section.

?

There is another way that may help, this does mean taking radio apart & you are warming to that, lots of video's.

Check the voltage on the back up battery.? Disconnect the main battery, press & keep pressed the power button,reconnect the PSU, this is with the sd card in.

?

Way before the above what program are you using to burn the card.? You have also tried a brand new virgin card. ?

Hi Keith

Me again. I have taken the x6100 apart and in a position to try your trick above to disconnect battery and then reconnect external power supply with SD card in.?

But I am just wondering what this process is actually doing ?

It seems important to understand it before doing it.

Thanks Simon
