GL-C-006P (mini) bricked after OTA update

[webns]

What happened?

I've updated GL-C-006P (mini) firmware via Z2M OTA update, after that, the controller doesn't respond to any commands (state, brightness, color...). The controller can still be paired/unpaired.

I assume it's the same issue as #22287 but in reverse — the mini controller got firmware for the normal version. I've tried to flash this version — https://github.com/catduckgnaf/zigbee-OTA/blob/3cdcc512f4cc589ab112ecc1ed0adf585fbea005/images/Gledopto/GL-C-006P(MINI)_20451203_20240227.ota but without any success, logs says:

Images currently unavailable for device 'GL-C-006P', hardwareVersion '2', manufacturerName GLEDOPTO, {"fieldControl":0,"manufacturerCode":4687,"imageType":5176,"fileVersion":604057601}'

Current state of the controller:

{
    "color_mode": "xy",
    "linkquality": 160,
    "state": "OFF",
    "update": {
        "installed_version": 604057601,
        "latest_version": 604057601,
        "state": "idle"
    },
    "update_available": false
}

What did you expect to happen?

Mini version of controller doesn't receive updates for normal version

How to reproduce it (minimal and precise)

Update mini version of GL-C-006P via OTA to latest version.

Zigbee2MQTT version

1.38.0 commit: fe048e6

Adapter firmware version

7.4.1 [GA]

Adapter

SLZB-07

Setup

Docker

Debug log

No response

Disabling OTA updates for GL-C-006P could be a good idea for preventing bricking more devices, at least while problem is being solving

[Koenkk]

Until it's more clear how to properly update these devices, I've disabled all GL-C-006P OTAs: Koenkk/zigbee-OTA@ae36142

[webns]

Noticed that both updates (normal and mini) had the same "imageType": 5138 but after the update in the normal version it changes to 5176 while the mini version keeps 5138. That's why it's possible to recover a normal controller with mini's firmware.

I've tried to edit imageType in the update for the mini controller but OTA update doesn't start with an error

"error":"Update of '0xa4c138a4688554cd' failed (OTA: Timeout, device did not request any image blocks)"

For now I have no idea how to recover mini version of the controller

[CoolID2]

I've got the same problem on two of my normal GL-C-006P.
Actually no chance zu bring them up again. The workaround #22287 won't help.

[webns]

Looks like the name of the controller doesn't matter, mini/normal is only a name, the real difference is the hardware they used to build the controller and we can't differentiate one hw from another

[Lukagian]

I have the same problem. I try to contact gledopto for a working firmware, I hope they will help us to recover the device.

It can't be installed because imageType of the firmware is 5138, while broken mini's imageType is 5176

With this workaround now I can control the device. But it is recognized as GL-C-008P.

Have you patched only header? I was trying to patch OTA update but my controller doesn't accept patched file with error thats says image is not correct

There is a list of different versions of the controller at the end of the OTA update

Maybe the same firmware can work on different controllers

You have to update two times
1st one to GL-C-002P/008P/007P
2nd to GL-C-006P mini

The problem is to detect right modification of hardware.

That's interesting way, will try later, thanks for your research and helpful information

One thing I'm sure about is that OTA updates should be disabled for any controllers 😅

[Lukagian]

After a restart of z2m the device was recognized as GL-C-006P. For me the fix worked great. Thank you very very much @Andrik45719

[Reinhard-M]

My device was also bricked. With the patch and step by step description from @Andrik45719 it's fixed, thanks a lot for this 😊

[webns]

Patch from @Andrik45719 worked for my controller too, thank you 👍

[robertoclg]

The fix worked great for my two devices. Thank you very very much @Andrik45719

[crazych1]

Maybe not in the subject, but suddenly who knows if it is possible to make the GL-C-006P_mini controller work at full capacity in neutral light mode? 12 volts per channel? In white or yellow light mode, the channel operates at 12 volts, but as soon as the neutral light is turned on, both channels operate at 10 volts. Maybe there's a way to fix it?

[CoolID2]

Hi,
I have the normal GL-C-006P. Unfortunately also bricked by z2m. Now I have installed the patch from Andrik45719.

• z2m rebooted
• device relearned
• It is also recognized as GL-C-006P
  But it cannot be controlled. It can only be switched off via z2m after relearning.

What am I doing wrong?
Or does this firmware only work with the 006P mini?

[Klikini]

@CoolID2 this issue (and fix) is only for the mini. Since you have the normal version, take a look at this one: #21988 (comment)
