You need bootloader first, then firmware.

It is possible that you have a (possibly old) bootloader already installed.  Go here and try this first because it is easier.  You need the section titled "Bootloader + firmware update example".  You can either search for that section or refresh the page (click in web address and press enter works best) if it doesn't take you to the correct section:
https://librepilot.atlassian.net/wiki/spaces/LPDOC/pages/5669026/Firmware+Tab#FirmwareTab-Bootloader+firmwareupdateexample

If that doesn't work then here are other ways.

If the setup you have running can flash hex files then go here to get a hex bootloader to install with your current setup:
https://forum.librepilot.org/index.php?topic=1384.msg27112#msg27112

If you don't have a way to flash the bootloader with your current setup then go here for instructions to flash the hex bootloader you got from the previous link:

After that you have a bootloader flashed.  Download and install the LibrePilot GCS that works on your version of PC, then go here to install the firmware onto the CC3D.  You need the section titled "Manual method".  You can either search for that section or refresh the page if it doesn't take you to the correct section:

If you still have problems, post back and tell us what the LEDs look like:

The led Blinking patter is normal that is same as working CC3D and I test with my another working CC3D


Serial port also showing
but it does not connect to the Librepilot
I used Manual Methord
Finally I clicked update & Erase button then connect the FC on LF then uploading firmware bar is going successfully and please wait massage long time and time out occur

You now have a working bootloader so you just need to install firmware that matches your GCS.

After that you have a bootloader flashed.  Download and install the LibrePilot GCS that works on your version of PC, then go here to install the firmware onto the CC3D.  You need the section titled "Manual method".  You can either search for that section or refresh the page if it doesn't take you to the correct section:

Sometimes the USB cable is not good enough.  Sometimes USB power is not good enough.  Maybe try a different computer and USB cable if you can.

It is important to follow instructions and UNPLUG USB, then click button on GCS, then plug in USB.

Try this:
- unplug USB
- go to Firmware page and click Rescue button
- THEN plug in USB
- then add battery power such as ESC with battery, plug the ESC servo connector to one of the servo pin sets on FC
- then click "Upgrade and Erase" or maybe try "Flash" also

Dear Sir

I did the steps that you have point out, Bit it did not success , and I have a another working CC3D FC which is working perfectly even USB power . 

Please advice to recover fault CC3D

Thanks in advanced

[TheOtherCliff]

What operating system are you using?  Windows, MacOS, Linux?

Does CC3D connect to GCS when you plug in USB?

If CC3D does not connect to GCS, try this:
- unplug CC3D from USB
- go to Firmware page and press Rescue
- plug CC3D into USB as it asks
- press Safe Boot
- does it connect now when it did not connect before?

I am using Windows 10

Does CC3D connect to GCS when you plug in USB?

Yes it is connected to GCS in DFU mode

I can upload firmware successfully using Rescue mode

Only issue is  CC3D does not re boot and time out is showing

I am using 2013 / 05 /28 firmware

How can I download 2015 firmware some time it may be boot

Please advice

[TheOtherCliff]

You should be using LibrePilot 16.09 (or LibrePilot next).

librepilot.org has a download link.

[PA3040]

Sir
I am using 16.09 already

Can you please advice the location of firmware once 16.09 installed

I am uncertain about what version you are using.  GCS version MUST match firmware version.  You must use bootloader version 4.

Firmware is built into GCS and GCS knows how to use it.  Use the following instructions to download known AUTHENTIC bootloader version 4, then install bootloader then install firmware.

Go here and try this first because it is easier.  You need the section titled "Bootloader + firmware update example".  You can either search for that section or refresh the page (click in web address and press enter works best) if it doesn't take you to the correct section:
