JVC Professional Customer Support - Firmware Upgrade

[Aaron Jones Sr.]

Wow, Awesome!!!

OK, for all you guys that are going to upgrade the firmware this is what you need to know.


GY-LS300CHU Firmware Update Procedure:
To prepare update SD card:
1. Uncompress the downloaded firmware file.
2. Copy the entire folder PRIVATE to a blank SD CARD.
To enter update mode:
1. Attach the battery and connect DC Power supply. Both must be connected to enter update mode.
2. In power OFF condition, press and hold MODE and ZEBRA/5 buttons together.
3. Slide power switch to ON position. Keep holding down buttons until FIRMWARE UPDATE screen appears on the LCD monitor. Release buttons.
4. Follow instruction of inserting SD card in SLOT B.
5. Update automatically starts showing progress bar.
6. When finished, LCD monitor indicates FIRMWARE UPDATE COMPLETED.
7. Remove SD card. Detach battery and unplug power source.

Notes: When you get through the process to this point the camera will be off and when you turn the camera back on it will go through a Diagnose Procedure. Don't be afraid because the directions does not mention this. Keep the lens cap on and acknowledge to go through the diagnose procedure. it will take about 6 minutes. After that make sure you perform the reset as the directions says and all will be well.

8. Reconnect power source. Perform RESET ALL from Main Menu>System>Reset All>Reset.
9. Select preferred OSD language.

I discovered the update process will not read the SD card in Slot B if you have another SD card in Slot A. My camera briefly reads Slot B and then nothing happens when Slot A is occupied.

After removing the firmware card in Slot B, I removed the card in Slot A then reinserted the firmware card in Slot B. The upgrade process continued fine from that point.

I wouldn't think this is unique to my LS-300 so hopefully helpful to those who run into the same thing.

I always save my settings to an SD card before starting the firmware upgrade process. Then I can restore them afterwards.

[Aaron Jones Sr.]

Is anyone else noticing the flip screen a little more clear? I'm not sure if it is just me wanting it to be a little more clear or if it actually is. Of course I am running the cam in 4K 150Mbs 30fps 4.2.2 maybe that is it, not sure.

[Stein Onshus]

I managed after some download issues and all effort on that - it was not available in .co.uk so I used the .com link here - to download.

Thank you for the link.

(- and as a happy camper I did the upgrade - and forgot to save the settings - ahhh. Well, I probably needed to further develop it anyway.)

[Nick Haman]

For future updaters, I didn't reset the settings, but can shoot 4k 4:2:2 - I didn't reset them with the last update either.

I don't think it'll result in anything strange happening, but if someone thinks it might, let me know haha.

[Luke Miller]

I follow the firmware update instructions to the letter. I turned my PC into a large paperweight by failing to properly follow the bios firmware update instructions.It was not possible to recover from the error and I had to replace it.

Can somebody post a link to jlog 422 4k footage at 150mbit to test?
Anybody tried Atomos output at 422 10bit 60fps and can post jlog footage?
Thanks, M

Is there a comprehensive list that has all the current things this gizmo can do (assuming the latest firmware has been uploaded to the camera)?

I'm basically deciding between the LS300 and the GH5. The image stabilization in the GH5 sure is attractive (something I know the LS300 doesn't have). Of course, there's lots of stuff the LS has that the GH5 doesn't.

Just kinda look at the two cameras stats....

PS - thanks for the info on how to upgrade the firmware.

[Marcello Mazzilli]

Thanks but I mean some footage straight out of the camera to download and work with. Youtube is compressed

Not that I know of. Each firmware update has its own PDF with the changes and their related settings. I have not seen an updated user manual that incorporates all of the changes.
