Yesterday I updated from this snapshot version 2016-04-18 17:30:08 to the last one 2016-08-20 00:21:07 (bullhead)

Everything looks in its place, but yesterday the device was keeping restarting, today it's stable. I tried to reboot it by myself and when boot it says:

There’s an internal problem with your device. Contact your manufacturer for details.

Any solution?

  • So, did you try to contact the manufacturer? And CM updater uses recovery to flash the zip so...

I have found a soulution here but it's for Nexus 6P and Android 5.1 but I think it will work in your case as well.

Android System

There's an internal problem with your device. Contact your manufacturer for details.

The problem occurs because of a check that Google implemented in Android 5.1 (and it seems stayed in after) which compares /system/build.prop with the values found in /vendor/build.prop.

If they differ you get that error message. All one has to do to get rid of the error is to change the 3 values in /vendor/build.prop according to the values in /system/build.prop.

On the link you can find a flashable zip. The magic is in the update-binary file:

/sbin/busybox egrep "^ro\.build\.(date(\.utc)?|fingerprint)=" /system/build.prop \
    | /sbin/busybox sed -e"s/^ro\./ro.vendor./" \
    > /vendor/build.prop

So you need:

  • install TWRP on your device
  • send vendor-build-prop-fix-signed.zip to your device
  • reboot into recovery mode
  • flash the zip but don't wipe anything
  • reboot your phone

If it's not work (but it should be work), you can try this method.

It says you should download and flash/install the vendor.img which matches your ROM's base.

  • The last sentence is the one on point. Update the vendor image and ignore the warning. CM uses a single branch for all devices so even when on the latest vendor image the warning will still pop up.
