• 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.

Hi @vadII


Hoping you can maybe help with this one, I have the Merida EOne Sixty 5000 with the Shimano steps E7000 / 60kn motor.
Recently downloaded licence for St Unlocker and all went well.
However when I change the destination from UK to USA it goes through the approx. 7 steps and then when I apply, for some reason reverts back to the UK setting of 25km (I’m obviously after the 32km setting

My partner has the FW 4.8 and my friend the FW 4.4 both of which have worked fine with the USA destination.

I have 4.6 FW, is this material?
Any ideas please???
It's because 4.6.0 is not supported and the App informed you about that. Downgrade to 4.5.0 or 4.4.0

Anyone knows whether changing the region and reducing the wheel circumference work with this new firmware?

@vadII Can you answer ?

According to the stated versions on the StUnlocker homepage its not included.
The eMax competition states about 4.9.0: However, currently it is not possible to process these modifications with our eMaxMobileApp. So please do not update to the newest motor firmware if you intend to optimize your bike via Bluetooth.
eMax has a working Windows version but that requires a Shimano SM-PCE1/02 instead of a smart phone.
The Eplus competition states: Compatibility of the Eplus Tutor Pro with Shimano 4.9 version is being verified.

Who will solve the problem first: StUnlocker, eMax or Eplus ?

I don't think the problem is what will work with that firmware - I see the problem now as losing your warranty with this firmware and all future firmware. This seems to be where shimano firmware, especially the latest version, is headed. It seems that 4.9 does exactly that - with previous versions we just don't know. It could be that shimano has been looking the other way previously? All we can do is guess, apparently.

So, @vadil, any info is there some problem if I buy a licence with 4.9.0?
No. 4.9.0 is 100% supported, except derestiction features. If you want to derestrict it - downgrade -> derestrict -> update back to 4.9.0 (but it's not worth it)

I am riding on 4.8.0 with all the features I need. Am I missing anything important by not upgrading to 4.9.0 or latter? Release notes are rather cryptic

My e-tube app is insisting that I upgrade to the latest version — by not allowing me to check/change assistance level — but I am concerned with losing ability to change markets and customise assistance settings.

Anyone have any real world experience of using this with the EP8 yet?

I do ... one week with it , no problems at all .

I didn't change the circumference, only change the market to "us" ... this way I don't believe shimano can give me any problems in case I need to warranty the motor.

Just upgraded my E8000 and SC7000 to latest version and now can't connect to ST Unlocker. Is there something I'm doing wrong, or do I just need to wait for the next release of ST Unlocker?

Good news, nice one. Yeah, be interested to know if Shimano are actually able to tell whether STunlocker's been used if you put it back to standard prior to a warranty claim..

Probably they do ... but they can not tell me the engine is broken because the market is different... and the command used was available trough Bluetooth.

Ok, I got it working. I actually updated using Shimano E Tube on my iPhone, and then tried to connect with ST Unlocker on my Android, which is the phone I normally use. I ended up installing E Tube on the android and connecting, then I could connect with ST Unlocker. Strange, but all is good again.

True enough, and US market 19.5mph would probably do me too. You pay your money and take your chances I guess. Good to know it's working on EP8 though. 1000-miles on my E8000 with no issues. Will probably see if I can try and live with the restriction at first when the new bike comes though, be on the safe side..

STUnlocker doesn't require ETube App installed.

The documentation suggested it
This is because many users who are unable to connect their bikes for whatever reasons state that this is a STUnlocker issue and submit their 1* ratings to Google Play / AppStore. So, in the manual we suggest to install 100% original Shimano ETube App and try it before blame STUnlocker

Hi @vadII ,
can yout tell me when the firmware version 4.9.0 will be supported?
Supported for a what? All non-premium features are 100% supported for 4.9.0.
4.9.0 was released by Shimano to avoid derestriction, it's only one goal. So it's not possible to derestrict motor with 4.9.0 via Bluetooth

To modify the wheel circumference, for example. Then I have to downgrade to 4.8.0 to do that?

Yes, EP8 is supported for derestriction on 4.0.2 (it's possible to downgrade to 4.0.2 easily).


I have no idea. PM me if you have this bike and we will test it
sorry, full de-restriction or just wheel circumference? Currently running 4.1.1
