I bought my E5Plus in December, while I was in the USA.
There, I printed some nonsense, to test the functionality of the equipment.
I took it apart and brought it to Brazil in February.
I set up the printer, and did some small tests, everything seemed OK, until ... Out of nowhere, the bed was no longer leveling, with each leveling command, the bed went down more and more.
I thought it was a problem with the BLTouch, bought another one, changed it, and the problem remained.
I disassembled all the electronics, wiring, checked connection by connection, cleaning all electrical contacts, updating the firmware, and, bingo !!! it worked ................ for 3 days, then, all over again, the same problems, m again I changed the BL | Touch, I checked connections, and nothing happened.
Today I tried to reload the firmware, so the problems have multiplied, now, the printer no longer boots, the screen does not load the status bar, and it is simply DEAD.
I tried several contacts with Creality, none returned.

If you can solve this problem, let me know, I have the same, I have already informed Creality and no solution has been presented ..
