sry to ask but
i´m stuck at 4.
"- Go to Device > System Updates and Press Update"
When i try to manually update
Validating update file.
the device just holds and aborts the update process. seems it cant validate the file correctly.
for now i tried: reboot after putting the file on the storage . redownloaded the file from different sources. checked if i edited the build prop correctly. seems everything is correct
maybe it matters if towel root is installed at the moment?
thanks a lot
