Update Letv 1s to Marshmallow 6.0 with multilanguage support

Letv 1s comes with China based software, which includes Chinese apps and services. There is also no multilanguage support. That’s why many users having this phone in Europe faces lots of difficulties when using it even in default English language.
Not long ago, we made a tutorial on how to update Letv 1s with great custom ROM made by Android programmer with nickname BB72. This custom ROM includes multilanguage feature and has no Chinese apps or services. Furthermore, major bug fixes were made for IR Blaster to work.

On 6-th of July, Letv devices received long awaited official Marshmallow update. As we expected, it came with no multilanguage support and filled with lots of Chinese apps that are useless in Europe. At least bugs mentioned above seems to be fixed. So we started to look for a solution on how to turn that cool Marshmallow update for international use. And here it is!

This tutorial is only compatible with Letv 1s (x500) devices. Do not try it on any other Letv model.

          Strange… Cause I’m having the exact device and done all the steps just to check if update is working fine and completed it without any errors. I also haven’t experienced any bugs in a half past year since using this ROM.
