Warning!!
Riding a tuned or deristricted EMTB is not a trivial offence and can have serious legal consequences. Also, many manufacturers can detect the use of a tuning device or deristricting method and may decline a repair under warranty if it was modified from the intended original specification. Deristricting EMTB's can also add increased loads for motors and batteries. Riding above the local law limit may reclassify the bike as a low-powered bike, requiring insurance, registration and a number plate.
Be aware of your local country laws. Many laws prohibit use of modified EMTB's. It is your responsibility to check local laws. Ignoring it, has potential implications to trail access, and risk of prosecution in the event of an accident.
We advise members great caution. EMTB Forums accepts no liability for any content or advice given here.
STUnlocker (ex Shimano STEPS Unlocker) Android & Windows App for derestriction/market change and etc

Hi, everyone. I just got a emtb with e8000 motor. Unfortunately it’s speed limit to 25km/h , pretty annoying when riding through woods. I do some research and find this Stunlocker ride app. Brought it and find a problem to connect to my bike.
1.I have no problem to connect with Shimano E-TUBE, but fail with this app.
2, on the app’s description page it says sce8000 display are not supported, but under this topic says test with sce8000 and works. I’m a little bit confused.
3, if this app not working with sce8000 display, is there any way I can unlock the speed limit? For example, by change the display?
Thanks for your time and much appreciated!

Hi, thank you.
Just download the app. And successfully connect to my bike.
it seems if I want to unlock the speed, still need purchase a premium license?
Sorry if this has been answered already…
Does derestricting an Orbea rise eliminate the “custom” tune that Orbea put on the motor? I love the adjusted settings I got 95% of the time, but there is a trail or two that I’d want full torque and a higher cutoff speed.

No. There is no such thing as the "custom tune". It's all marketing stuff
The EP8 RS has software torque and power limiters that can be modified without the Premium license.

!!! Warning !!!
As you may know, the STUnlocker App automatically (if the Internet is available) gets and apply the Premium key if it has been issued.
I was informed today that some Shimano dealers are using the STUnlocker App to check if the Premium license has been issued for a bike or not. So I made the decision to temporarily disable this feature. So, now you will have to register the key on a new phone manually.

Hi Vadll, I intend to buy a license. I have as Orbea Rise M10 with Shimano EP8-RS. How can I pay? Can you send me a PM (personal message) please? Thanks

Connect the App with your bike and click on "Get the Premium licence"

Presumably, simply using the (non premium version) app to check battery condition and number of charge cycles etc in no way invalidates any warranty? Would be nice to have access to those metrics.

I can not modify NM and power from the defaults settings. I have an Orbea rise M10. I only get the defaults. I am using the free version 2.0.17.51 for windows and SM-PC02. thanks

I have tried the ST Unlocker on My Shimano e8000 motor on a Focus Jam2. I bought the premium app but I cannot get the US setting to hold on the bike, it reverts to EU when turning the bike off/on, yet if I change other parameters such as Wheel Circumference it works.
Am I doing anything wrong?
Any advice would be appreciated.
Cheers
Andy

Perhaps do the US setting change - then delete the old firmware and update to the latest firmware from Shimano. However doing this will make you have to go through the process again should you want to change anything else in the future.

The App informs you about non-supported firmware, why don't you pay attention to it? Anyway, downgrade the firmware to the supported version and derestrict your bike. You can upgrade firmware back to the latest after derestriction

Sorry vadll, I thought I had correct firmware? I will investigate changing that. Thank you.

why you saying sorry? did the app notify you what he's suggesting?
Anyway - if you followed the instructions and loaded the "cracked" firmware then you did the right thing. If you updated to Shimano latest after that with up to date versions then you will need to roll back

I have an Orbea Rise that I put a 27.5 wheel on. @vadII With the premium version of your app I'm not seeing the option to change the wheel size. I assume this is due to the app not being compatible with the firmware on the bike? Will an updated version of the app be available soon or should I downgrade the firmware on the bike? If I need to downgrade can you please direct me to instructions? Thanks.

I don't know if there is a wheel size option, but definitely an option to change wheel circumference as this was out on a new motor and my distance kept coming up wrong on strava.

I meant change circumference. All I see on that screen is the speed correction slider.

Did you read the App's manual?
Anyway, it means that you didn't apply your Premium licence

I got the modal dialogue that said the premium license was applied, but I'll try again tomorrow. The license was previously applied on my old bike. I'm thinking that may be the issue. Is the license transferrable to a new bike or do I have to buy another one?

The Premium licence is per one bike's motor (serial number). It can't be transferred.

@Vadll, can the app be transferred from one phone to another? For the same bike.

Yes, sure. You can use your Premium licence on any iOS/Android/Windows device

5 mph makes all the difference! I was overtaken by a pro cyclist and I felt like a bum... with my e-bike...Could not agree more that all we EU guys want is the increase from 15 mph to 20 mph.
I want to leave everything else as is but that 5 mph makes all the difference.
@vadll
Please can I contact you regarding getting the software please?
