I've been trying to get the Europe_870_3406 (335) map running on my TT Go 730. I installed it on an SD card and Easyusertools reported everything was ok. However the TT gets to the splash screen and then reboots. I have to do a hard reset (sometimes twice) and remove the SD card for it to work again. Any ideas what might be going wrong? I've been running a TT one V2 for a while no problem so I'm fairly familiar with Easyusetools etc.
