How to Fix a Bricked Creality K1 or K1 Max. 

oh my case today. How can I connection 24v USB micro?

Answering my own question after some thought. 24v you can get by connecting the motherboard directly to the printer power supply, with the red and black pins With a notebook or by bringing a printer close to the computer, you will be able to connect the motherboard to the 3D printer source and the USB cable to the computer and the motherboard

Yes you should be able to do this without disconnecting all the wires, as long as you are able to get the cord in. The cord we were using wouldn’t go in though so just assuming a lot of people will have the same issues. But if you can get it plugged in without disconnecting, definitely save yourself the time!

Hmm that’s weird, I’m not sure why it wouldn’t be there

Same here, I've contacted Creality support and am waiting (day 3 now) for them to update my support ticket. I did find a reddit post titled "No Micro USB Port Anymore (K1 non Max)" from about 6 months ago that says, for some reason, Creality released boards without this port soldered on for a couple months back in August/September of 2023. I bought my K1 on Black Friday 2023 from Creality and was considering myself lucky to have gotten the newer version with the good extruder, only to now find out i got a defective mainboard. I bricked mine trying to reset back to factory firmware so i can update the K1 Helper Script & it just has a Creality logo on the screen now. At first it has a blue bit sliding through the logo before it just goes to a static Creality Logo. The recovery method here is the only other way to flash firmware to the board & I am unable to do this recovery process without this micro-USB as it won't work from the front USB. The spot is there for one to be soldered on, but i don't have the tools nor the skill to pull that off. I advise anyone in a similar predicament to contact Creality Support, especially if you're within your warranty period. Best case is Creality sends a new board, worst case I have to buy one for $80. They'll want a copy of your purchase invoice, photo of the serial number, photo/video of the issue, and your email, just a heads up. They seem to have neglected my J1 pins as well.

Is your device reading the board?

Same here and mine my computer is not reading the board

@@RafaelKaname stolen from what someone suggested on a bricked KE vid: For those having problems with the unsigned drivers, you'll need to boot windows in recovery mode (Shift + Restart) and then Troubleshoot > Advanced Options > Start-up Settings and press Restart Then on the Startup Settings, press 7 to select Disable Driver Signature Enforcement. This will restart your Windows and you would be able to install unsigned drivers

I thought it was on all of them. When did you get your printer?

Not 100% sure, but out of nowhere it stopped working properly. Until now we didn’t think we had the time to fix it, but this is a fairly quick fix.
