i have just fitted a new 4.2.7 board that i ordered from the store and after rewiring the extruder stepper as it was running in reverse, i am now struggling to level the bed as when i click auto home then go to steppers it only released all not the x on its own any ideas

i did find the right programmer and no matter what firmware i flash it doesnt work, i get 3/4 of the ender logo appear then it stops
i have ordered the 4.2.7 board from creality to replace the 1.1.4 8bit board

I used the arduino ide to flash the marlin snd I since tried to flash the stock and found out why i kept getting the error but no matter what firmware I flash for the 8bit board it won't work I get the ender logo start to load then it stops 3/4 the way and won't start

I ha e the 1.1.4 board in my ender 5 and I updated to marlin with bltouch and bootloader and it didn't work so I tried to go back to stock but nothing I do works
I have downloaded the ender 5 about firmware for the 1.1.4 board witch is version 1.1.6 and no matter what version. I flash it doesn't work I get the ender logo staring but doesn't finish and I have a knackered ender 5 can anyone help with this please

i tried that and i flashed the bltouch with audino uno which i am trying to find but with trying the default flasher i have no firmware now on the board ahh

i have a stock ender 5 with bltouch
i flashed my board to have bltouch and i dont like it and want to go back to stock firmware how do i do this, i have downloaded progisp v1.72 and the firmware from the downloads page but i get 'cannot open file "location" the system cannot find the path specified'
how can i flash back to stock firmware
need help
