Unlikely - just download the full update and flash it in TWRP... then install TWRP before restarting
I'm not an expert with this but I believe it flashes to the partition you aren't currently using, but when you reboot it will switch to that partition... you would need to flash it twice to have both partitions on the same ROM, but I don't think its necessary
Version: V126.96.36.199.SLBEUXMSince yesterday there is a new update for the Global EEA version.
The date of the security patch is still 1st of May so it is not clear what the changes are.
Will try to find out and post it here when available.
