Hope someone can help.
I've been using unlocker for the past 3/4 months and must say it's brilliant.
My firmware is 4.3.2 so can change everything.
My problem is I am thinking of changing bike so if I sell it private or trade in at LBS want to update firmware to latest.
BUT it will NOT update.
Using Etube says updated but goes back to 4.3.2.
Any ideas

If you downgraded per the eMax instructions did you run Remove-Downgrade-Files.bat at the end? If not, Etube may still think the latest firmware is 4.3.2.

Hi. Yes removed files. And deleted Etube and reinstalled. When I update it looks like like it's done, goes up to 100% then I disconnect and go back in and it's back to 432

If the sm-pce02 or sm-pce1 via eTube on a PC is not getting the job done you may want to try using the Android or iOS version of eTube on a phone or tablet. After downgrading my bike's firmware I could only get it to update via eTube on my phone through Bluetooth. For some reason I could not get it to update via the sm-pce02.

To be safe turn off any auto lock / sleep timers on your phone so the firmware can fully update without your phone going to sleep.
