B87 EX X2 Issues

[SpoodenMember]

I’ve been using my B87 EX X2 for the past day since I just got the keycaps for it (GMK Sky Dolch). I woke up this morning and turned on my PC, the RGB LEDs were not working, only one was on in the top left of the keyboard and it was flashing green in a random pattern. A few minutes later, the keyboard itself stopped working and started typing random numbers and commas when keys were pressed, except the B N and M keys that dont work at all, now BootMapperClient just says BAD on every key in the keymap section when i download the keymap from the board.

Anyone have any ideas on what i could do to fix this?

Thanks 🙂

EDIT: My key layout is ISO UK if that matters at all.

EDIT2: Plugged it in again, no LEDs light up and i get not response from pressing the keys at all, keymaps wont upload but i can enter Boot Mode by pressing LeftCtrl when I plug in the board still.

Hi

Sorry for your inconvenience.

I think there would be some bad solderings.

1.Could you tell me your order number?

2. Could you show me your PCB?

3. Could you show what keymap you used?

Thanks.

Order number #3660

Below is my PCB

The keymap I used was provided by default when i plugged in the board, before i installed BootMapperClient. It is the UK ISO default.

Hi

1. Could you try to connect it while pressing the key “U”?

2. Could you upload new firmware file?
– file download : https://github.com/showjean/ps2avrU/releases/download/V1.3.0/ps2avrGB_firmware_V1.3.0_170321.zip
– firmware file : ps2avrGB_NKRO.hex
– keymap file : keymap_gb_EN_B87(EX)_mini(EX).hex

3. This page explains how to solve you problem.

4. If nothing is working, you had better to send it to me to fix it.
My email address is “flashteker@gmail.com”. I’ll let you know how to send it back to me.

Thanks.
