Yongnuo YN685: How to upgrade the firmware (notice the warning!!)

[@robertopatuelli5020]

I succesfully and smoothly updated my YN685 for Nikon using Windows 10 following this video but with these steps: - first update your trigger YN622-TX to last firmware (MODE+ POWER ON) (firmware: YN-622N-TX_FW_V1.13.dfu) - second update via trigger the flash unit (on trigger GROUP+POWER ON) (firmware: yn685n_offical_fm_v1.41.dfu) IMPORTANT TIP: trigger updater and flash updater are two different programs that you can download from Yongnuo web site. With the trigger updater program I also succesfully updated firmware on a pair of transceiver triggers YN622N II (CH/AF+POWER ON 622) (firmware: YN622N-TRX-II_FW_V1.03.dfu) Of course all batteries charged, if you break firmware update results are impredictable.

Thank you for sharing this Roberto! I have pinned the comment for everyone to see it! 🙂

Dear Roberto, Where can you found yn685n_offical_fm_v1.41.dfu firmware? Could you send me an URL, please?

[@arsetyawanpratama1929]

i was stuck in 000 mode in 685C, but after i change file name (From yn685c_offical_fm_v204.dfu to 685_204.dfu) and it works, i'm very happy to share this.

[@frederikboving]

Thank you for sharing Arsetyawan, hope many others read your post and make good use of the vital information here!

thaaaaank you 👍👍👍👍👍👍

Tip: use FULLY charged batteries. The firmware upgrade to version 1.40 bricked both of my YN685N (one at a time). After the upgrade, the first unit did not restart and the display showed three "squares" instead of the f/w version number. I tried to do it a few times, following the instructions step-by-step, with the same results. A few minutes later, I decided to put recently recharged batteries and I managed to successfully upgrade the first unit. I removed the batteries, put them at the second unit, followed the steps and got another bricked unit. It took me a while until I decided to put a different set of fully charged batteries and run the flash updater. Maybe it was a coincidence, but the "new" batteries were the only different thing I tried in both my speedlights.

[@frederikboving]

Fabricio Braga thank you for sharing Fabricio - the upgrade process is apparently very fragile and using fresh and fully charged batteries seems like a good idea. Hope others read this post and benefit from it. All the best.

[@michelassenheimer676]

I failed first upgrading to any version 1.33 1.34 1.38 1.40. When running the YNFlash Updater software in Win10 in Win7 compatibility mode, it works. I am now at 1.40.

[@rickkremer0525]

HELP!!!!! I bricked my YN685... I updated sucessfully the 622TX, but the flash never restarts after the Flash updater show sucessfull? Its stuck at 000. I tried running in the APP in Windows 8 mode, and putting the files in the root of C... Ughhhh any suggestions?

[@frederikboving]

Sorry to hear about your experience! My best suggestion is to take the batteries out of the 685 and wait for 5 minutes but I am not sure it will work!

[@frooxiegamer]

Damn. I have allready ordered new yn986n after bricked yn685. Then "accidently" come to this video and after reading some comments tried update several times to fw v1.4. so after 20 tries I have successed to unbrick the flash. Well it seems like I will have two flashes from now on. :D

[@frederikboving]

Ha-ha! Glad you finally made it! Two flashes - well, as @danielnorton says: the more flashes, the more you get paid :-D

[@julianrullifotografia1615]

hello, i have the same problem ... i tried to update to 1.40 on my YN685N and it bricked.... did you tried 20 times oon windows 10? cause i dont have win 7

[@u-teske8875]

Vielen Dank, hat super funktioniert !

[@giusmelix]

It works also on YN685 Canon with YN622C-TX

[@cbpunk8366]

Hello I cannot find firmware for YN560III

[@frederikboving]

I cannot even find a homepage from Yongnuo!

[@danielmeneses4398]

I can not connect the YN 622 keeping GR + ON pressed but yes, I can access the PC mode by pressing MODE + ON, but even so, I do not get the option to start updating from the program, what can I do?

[@danielmeneses4398]

I must add that on the screen of YN622 the name YN685N does not appear as you show us in the video, help

[@frederikboving]

Hi Daniel, sorry, I am not able to re-produce the situation you describe. The best advice I can give is to try to rename the file so that all "funny" characters are removed.

[@JulioCesarGarciaGarzon]

@@danielmeneses4398 friend, have you solved the problem yet? The exact same thing happens to me, if you could solve it, it would be good if you could help me, thanks

[@sebastianochoa7780]

What do the updates do? Do any of them make battery life better? Can you update to the latest from the first one directly? Thank you!

[@frederikboving]

Hi Sebastian, normally there are release notes, so you can see what the updates relate to, but I doubt the battery life improves. Normally it is bug fixes and maybe some improvements in the communication between the trigger and the flash. As far as I can see from the Yongnuo homepage (www.hkyongnuo.com/e-detaily.php?ID=377) there only is the latest software on the homepage, so it would be strange if you cannot update from your version to the latest, but I think the safe answer has to come from Yongnuo.

[@crollinsphoto]

Question: I have a 685 with a firmware of 1.2.2 and it will NOT go into Update mode. I have held down the MODE button like the others and they all went into update mode except this one. Any thoughts?

[@frederikboving]

Just so I am sure I understand: You have several 685's and and you have successfully updated them all but one, and the last one will not go into update mode?

[@crollinsphoto]

Yes, the oldest one with firmware 1.2. Got an email from Yongnuo and they said all firmware 2.0 and below can only be updated by sending the flash to their repair center in China to be updated to accept firmware updates. Forget that.

[@frederikboving]

Right. Thank you for sharing this info, although bad news. Hope others read this comment and save some time trying to upgrade!

[@Wildtapirx]

@@crollinsphotothat is really stupid. I have the same problem. Thx for sharing.

[@imsamurai1]

if flash stuck at updating screen try to flash again and again (do not turn off transmitter or flash) untill flash successfully reboots. For me it was 3 times.

[@frederikboving]

Hi, thank you for sharing!

[@arteenfocofotografia]

hola te consulto me quedo firmware en 000

[@frederikboving]

Sorry, not good at spanish: The only suggestion that I can think of is to check if the file name has some "strange" characters in it. Try rename the file to something plain using only letters a-z and digits 0-9, maybe that can help.

[@arteenfocofotografia]

@@frederikboving hola instale todo en otra pc y despues del tercer intento pude instalar firmware . Yo para si alguno le pase lo mismo

[@frederikboving]

@@arteenfocofotografia Hi, so you installed everything on another pc and after the third attempt you could install firmware! In other words: success! And you mention this if someone else should be in the same situation as you - thank you! And good job!

[@lutero2000]

Thanks!!! 🙏🏻

[@tenonix1689]

Question: so I can only update the flashes using windows 7?

[@frederikboving]

No. I upgraded using windows 10. But for a small fraction of those that go through the update, it turns out bad. The upgrad leaves the flash bricked and useless. I have not been able to diagnose the problem (and I did not have the problem as most others), but I have read that some of those that get into trouble can fix the problem by changing the filename or do the upgrade via windows 7. So if you want to be safe and avoid bricking your flash, then don't do the update at all.

[@RODOMILJ]

@@frederikboving Just both two YN685N speedlights. Updating first one passed in second attempt. Updating second one took 37 tries. I almost gave up. I think being persistent paid off. It was very frustrating turning on and off every time. But now I am very happy. Both work excellent using YN622N

[@frederikboving]

@@RODOMILJ Good to hear! Any idea what made the difference after 37 attempts? Or did you do exactly the same every time, and suddenly it just worked? I ask because if you have a variation or a twist that makes the difference, then I am sure we are many that would like to know / understand...

[@RODOMILJ]

​@@frederikboving I did try anything it was suggested on the Internet KZbin included. Replacing batteries with freshly charged ones, trying to reset to factorys values (not possible), trying different files, etc. Nothing worked. After all was left to cool down (and after long coffee) I came to assumption that I have to treat the flash as in perfect state, and that all is to blame is software, or wireless transport from YN622N to the flash - so, I started repeatedly updating with the latest software 1.40.dfu using recommended procedure from Yongnuo website - attempt, after attempt...very soon I decided I have to start counting, and NEVER to stop until something different happened (desperation?). And it did after 37th try.

[@frederikboving]

@@RODOMILJ Good job! I guess that persistence is a key component in every success :-D Glad you made it - hope your story can inspire others!
