Thank you for your reply.
It's possible for you to share files of those old fw version please?

Try this. Came straight off my phone with a stock standard ETube app

does stunlocker unlock ep801 ?

 

[aarfeldt]

No.....but you can use eMax tuning.

Hi Vadll,

Do you know how the "Regulation change history" for a DU-EP800 works?

I had a user report with a red warning.
Then after reseting to default settings its no longer marked red but there is a timestamp for a regulation change.

Is this all the information the DU stores, that a change has taken place only, or dose it store more information?

This is not STRide related question. Anyway, STUnlocker informs you which settings are not default and you HAVE TO change all settings back to default/stock before visiting dealer/shop center.

Right, my mistake. I just jumped into an active conversation with you in it. Should have been more active in choosing the right thread.

Still, do you have any knowledge about what happens on the Shimano side of things and how permanent/visible they will be?

See my previous post...

I understand that the full accountability lies with me as a user, i am not questioning that and i understand your apprehensive reaction to my question. I am in no way waving my own total responsibility for using the software. I am only here asking for information that you may or may not possess about how shimano's "Regulation change history" works. Call it academy curiosity i you will

 

[vadII]

You can see the "regulation log" in the STUnlocker. STUnlocker does not write into the log any data. Regulation log is used by Shimano to compare current settings of the motor with the factory settings. If you change settings to default you'll not see any warnings in Shimano software and Shimano will not understand if your bike was derestricted or not.

EP801/EP6 overall Torque/Power settings are now adjustable in then new 1.18 version
So it's possible to make EP801/EP6 RS into the full power motor via Bluetooth

How soon will wheel Circumference changes be available with the ep6 and ep801 motors?

 

[Singletrackmind]

How soon will wheel Circumference changes be available with the ep6 and ep801 motors?

Does changing the wheel circumference settings to a "smaller" size allow the ability to increase the max speed?

That is correct!

Can a EP8-RS be derestricted via bluetooth? Or can this only be done via the pc interface? Also does the motor need to be on a specific firmware version to be derestricted? thx

yes, as the normal EP8. For Bluetooth you need downgrade to 4.0.2 for the speed derestriction and then update to the actual firmware. With PCE interface the downgrade is not required.

 

[Big07]

yes, as the normal EP8. For Bluetooth you need downgrade to 4.0.2 for the speed derestriction and then update to the actual firmware. With PCE interface the downgrade is not required.

Sorry, what do you mnean by "then update to the actual firmware"? I used stunlocker with an ep8 on a different bike. That time I just downgraded the firmware and have never updated the firmware since.
With the EP8-RS, do I downgrade the firmware, edit the cirfumference/region,etc.. and then afterwards upgrade the firmware? When upgrading do I use e-tube? or upgrade back to a specific version?
Also if I downgrade the motor firmware I could still edit the power/assist levels on the ep8-rs, right?

 

[vadII]

Why? The downgrade instruction tells that you have to update to the actual firmware, because 4.0.2 is too old and has many issues.

With the EP8-RS, do I downgrade the firmware, edit the cirfumference/region,etc.. and then afterwards upgrade the firmware?

Yes, exactly

When upgrading do I use e-tube? or upgrade back to a specific version?

Yes. To any, including the latest

Also if I downgrade the motor firmware I could still edit the power/assist levels on the ep8-rs, right?

No. 4.0.2 does not have PW/TQ settings. This firmware does not even know about RS version. 4.0.2 is required for the changing settings via Bluetooth only.

Ok, thank you so much. I wasn't aware that updating the firmware still allowed you to keep the modified speed settings in place.

Question about derestricting a EP8.
A few months ago I downgraded the firmware on my ep8 and have adjusted the wheel size, etc.. However I have just left the motor running the lower firmware version.
Should I now update the firmware on the motor? If so do I just use the shimano e-tube app to update to the latest version?
I assume that if I update the firmware and then want to adjust the wheel size, etc.. I'll need to downgrade the firmware again, is that correct?
Just wondering if it's worth upgrading. I've heard that the older firmware has some "issues" but I've never seen any description of what those issues actually are.

I have PCE cable so I can change Shimano EP800 RS to full power 85Nm directly???

 

[Big07]

Yes, that is correct. You can also do it via bluetooth as well. The advantage of the PCE cable is that to cvhange this setting you do not need to first downgrade the firmware.

ok thanks

Can someone suggest a fully functional file manager app which allows copying FW files across to the /Android/data/..... file systems for Android 12? Previously, I have successfully used "Cx File Explorer" but it seems Android no longer allows 3rd party access. Cheers.

 

[webman]

Any should work. You just need to enable access in the settings. Normally the app (file explorer) will pop up a notification and ask you to change the settings. I use root explorer

Many thanks for your reply. I tried root explorer and this worked perfectly.

@vadII - mate's bike needs to go back for warranty on the motor. Can I just change everything back to default settings on Stunlocker and then connect to Etube and let it update everything to the latest firmware without a flag being set or similar?

Yes, you can

I have a 2021 orbea rise with a doggie ew en100 and not a didplay. Can I still use stunlocker to derestrict the motor to get 85nm? (Btw-I enjoy st ride and so don’t need/want a display)

Yes

Please send a link to where I would figure that out for a Mac IOS.
