dani31 Posted July 12, 2020 Share Posted July 12, 2020 Hello,Please help me I'm desperate!I tried to put my brand new KS16S v2 never used from version 1.09 to 2.02 firmware.I tried it with the iOS KingSong app and the app told me that my wheel was already up to date.Then I tried with the iOS SoftTuner application, I chose 2.02, the update started and the wheel went off.Now when I try to turn it on, it turns off immediately, I have to press continually the power button to activate the bluetooth, if i release power button the wheel turn off, I don't have any serial number in the applications and no firmware is visible, in the KingSong application it says "?" for the firmware version.Please help me I am so desperate !!Thank you,Daniel.

travsformation Posted July 12, 2020 Share Posted July 12, 2020 You can connect to the wheel from the app, right? Plug the wheel in to the charger, it will allow you to stay connected without the wheel switching off. Then check in the app for the "auto-shutdown" function, it might have been set to 5 seconds or something. If that's the case, just move it to the max. (240 minutes) and problem solved. Hopefully that's the case. Give it a try and if it isn't that we'll move on to the next possibility. But don't panic, wheels bricked during firmware upgrades can be recovered.

dani31 Posted July 12, 2020 Author Share Posted July 12, 2020 Thank you for your answer. I tried to plug in the charger but it's the same, it's like there's no bootloader anymore. When I press the power button and release the button the wheel turn off immediately. If I press the button to turn on the light it's the same, the wheel turns on and off immediately. If I press continually the button the wheel says "bluetooth is off" but the connection with the application works, but if I release the button the wheel turns off immediately.

dani31 Posted July 12, 2020 Author Share Posted July 12, 2020 If I try to change the shutdown parameter it doesn't save the settings, no settings can be saved. I think it's serious and a change of motherboard is the only solution, it's completely crazy. Quote Link to comment Share on other sites More sharing options...

The wheel doesn't need to be on to connect to the app and change the settings, I can connect to both of my KS wheels when they are plugged in, without turning them on. Try with EUC World on an Android phone, I don't have much faith in KS apps... 16 minutes ago, dani31 said: I think it's serious and a change of motherboard is the only solution, it's completely crazy. A firmware upgrade shouldn't damage the board. Do you know the wheel's serial number? Maybe @Seba can help you out Edited July 12, 2020 by travsformation Quote Link to comment Share on other sites More sharing options...
dani31 Posted July 12, 2020 Author Share Posted July 12, 2020 Thank you so much for your help. Yes, I know my serial number. I just tried to plug in the charger and the app doesn't recognize the wheel, as I indicated above I have to press the button continuously for that.

KS's app is....not great. Don't loose hope, maybe there's still a solution that doesn't involve changing the board Quote Link to comment Share on other sites More sharing options...

If you're registered user of EUC World (I mean that you have EUC World account and you have signed in in app), please send me an email with following informations: serial number of your wheel Bluetooth address of your wheel (you'll find it on the device scan list that is shown after you tap on "Bluetooth" icon in EUC World, it looks like AB:CD:EF:01:23:45 and is located just below your KS-16S Bluetooth name) your EUC World username or email assigned to this account My email address is sebastian@euc.world - I assume that your wheel is stuck in bootloader mode. If this is the case, EUC World can be used to resurrect your wheel and make it alive again 7 Quote Link to comment Share on other sites More sharing options...
dani31 Posted July 13, 2020 Author Share Posted July 13, 2020 Unfortunately I think my motherboard's is bricked. Changing the motherboard is too complicated for me, there are places where there is like glue on some connectors. I'm thinking of selling the wheel for a handyman, what a sadness.

Peters Posted July 16, 2020 Share Posted July 16, 2020 (edited) Hello Im having the same issue... please help ! Kingsong 16X unresponsive, power button does not do anything, when on charge it does seem to power up and connect with app, yet it does not balance at all. Here is a video to show you whats happening. Thank you in advance for your help. Firmware 2.02 Serial: KS16X2B190907P090 Bluetooth MAC: 4C:24:98:81:1B:35 Edited July 16, 2020 by Peters Quote Link to comment Share on other sites More sharing options...

I would say that there is a problem with power button circuit - button itself or wiring. Motherboard seems to work correctly as it correctly turns on after plugging the charger in. 1 Quote Link to comment Share on other sites More sharing options...

It won't balance after plugging charger - it's completely normal. Again, I suspect power button circuit and it needs to be checked first. Mainboard may be perfectly OK. In KS-16X power buttons sometimes fail, especially when wet. 7 Quote Link to comment Share on other sites More sharing options...

Seba, thank you for your suggestion and YES you are correct. Upon opening it, it was indeed a disconnected power button plug. I reconnected it, secured it so it will remain connected and all is working good now. Thank you once again ! 4 Quote Link to comment Share on other sites More sharing options...

I've done so on mine and ridden in torrential rains without issues. I also plan on opening up the wheel whenever I get a chance to and spraying some on all connectors susceptible to being exposed to humidity (from bottom of the shell and possible water ingress from the trolley handle cavity) 1 Quote Link to comment Share on other sites More sharing options...

Aristocrat _ninja Posted August 16, 2021 Share Posted August 16, 2021 Hello, I got kingsong ks14d Model no ks14d1b200626f004. Did the firmware update. Smh connection broke and now I'm in the loop. Trying to update it. On euc updates to 100 percent and nothing happens. Phone says that it's connected, I press the button to turn on the light, the app responds but the wheel nope. Tried to turn the wheel upside down, keep charging all the time but can't get out of the loop. Please help. BTW if I keep pressing the power button for 10s straight the wheel just keeps constant beep 1 Quote Link to comment Share on other sites More sharing options...
