I tried the root method with a fresh installed (force update after full wipe with twrp, the back to Stock Recovery) P7-L10V100R001C00B133SP01 ROM - failed! The same method with my orginal B121SP01 Firmware was for a week successfully, maybe the RootGenius don't work with the new Firmware?!
I will try a new fresh installation with B121SP01 Firmware, then rooting the device and then flashing the update B133SP01 again with the standard method.
Someone knows more details about P7-L10V100R001C00B133SP01 and root access? Is it possible to remove the 'set_immutable.list' file? Under B121SP01 that was not a big problem.
By the way, my old full backup (FW B121SP01) with Twrp 2.8 faileds flashing back to after I updated for a few day to B133SP01, maybe the update repartitions the device.
But restore backup with twrp 184.108.40.206.
With new twrp will failed on data section.
