mt7-l09v100r001c00b145 open bootloader rooted back to stock and update to Marshmallow

Hi all, I've an mt7-l09v100r001c00b145. As I remember with patched firmware with cwm and open bootloader for root. So a update to the OTA version MT7-L09_WestEurope_C900B331 fail.

I tried to to a restore of a full TWRP backup from this sources: http://ift.tt/1PmgI7y

But both B571 ( Europe ) ---> http://ift.tt/2cYdv0m and B571 ( Europe - non root all stock ) ---> http://ift.tt/2dmkSld could be restored, but phone will not boot.

So I need a strategy ideally to go back to stock boot loader and recovery, to update the OTA updates and at least with ROOT feature. Ideally a update strategy, to save all application settings.

If this is not available, I would like to do a force update of a FULL working rom. But need hints for the correct strategy.

Best thanks!
