GO Live 1535M screen turns grey and freezes then reboots continuously
I have found, that if I hold down the power button and keep it held down until the device reboots to white diagnostic text, I can then press the power button once to turn that off, then hold down the power button again until the device turns on. From there, 1) it may be fixed and operate normally, 2) it may freeze and reboot once, then operate normally, or 3) it will reboot continuously and not be fixed. In the case of #3, I can repeat the above procedure until I get a #1 or #2 result. I have found in most cases doing the procedure twice will work. However, after some number of hours, the device will start freezing and rebooting again, and the procedure will have to be repeated.
I am able to hook the device up to a Win10 PC and run MyDriveConnect. It does ***NOT*** show a Navcore update for the device to address the Week Number Rollover, which is strange because I am aware that there **IS*** a Navcore update for the 2535* and even the old *10 devices (910, etc.).
Not sure what is causing the behavior in the first place. I found a thread where people were having similar freezing issues with the 1005 only after the latest map update. They found that deleting the whole map and loading only certain zones via MyDriveConnect would stop the freezing/rebooting.
I tried e-mailing TomTom support and got a form reply telling me to back up favorites, do a "factory reset" within the device menus, then following the procedure listed here: https://us.support.tomtom.com/app/answers/detail/a_id/2053/. This procedure as far as I can tell is for restoring the Navcore software if the device won't boot at all. I haven't tried this yet because I don't want to lose all of my settings, only to find that this doesn't solve anything, since the info in the above linked thread seems to indicate that this is a problem with the map.
Can anyone confirm if this is happening to them, or have found a fix for the 1535M for this issue?
