Kess V2 4.024, and reset the token. Cpu locked

[Fabiuz]

I was reported this strange case.
As we all know, or should know, the fw 4.024 is CRP2, then as the old 3.099, you riscriveva the cpu with the jlink and was inspired by the sd.
Well, a friend with the 4.024 have finished the first 30 token and jflash continues to tell him the cpu is not found.
So I replicated the case, without, of course, the end of the token.
Soldered the cable to the jlink on kess v2 3.099 and put 4.024, and rebuilt the SD card, ok the kess works.
Without desoldering anything, restart the j-flash arm and "cpu not found"
What the hell happened? The cpu should not be blocked.
Can not connect more without even having disconnected the cable 20 pin from kess.

I'm sorry that those who know do not speak, it should be of interest to many, given that it is a very good firmware 4.024, FULL and EUROPEAN, tractors, boats, etc.... really, and not like the old 3.099 that he was only active icons and no Iveco Daily EDC16C39 usable, all in grey.
Anyway, I solved it.
Free JTAG Jlink is mysteriously closed.
But they remain the UART, and the Uart works, connected to the bootloader of the KEss without problems.
You can close it.

Colleague has fixed by reflashing the fw 4.024 format .hex HEX, with U-Link + format and rewrite the SD in FAT32 with the files that are cleaned of the fw 4.024
Being the fw 4.024 a hex when converted to .bin and co-written with J. link when, in terms of writing close access to the JTAG. Only the UART remains active.
