Many other shops use dealer ROMs and can also offer German and other languages on the devices. The problem with such dealer ROMs is that you can no longer update and it can often happen that there are Trojans, spam-ware or viruses on it. We avoid this by using only the official ROM, even if that means that we can only offer a device with English / Chinese.
Many customers then come to us and ask us if we can flash their devices, where we unfortunately have to reject. The Dealer ROM have been installed by way of detours and often prevent a normal update or flashing.
But we offer every customer the help of the official flashing or update and have written detailed tutorials, which can be found in our blog on TradingShenzhenBlog.com
