Now i have B132 with 1,5Gb System Partition back, yeee.
What have i do:
-install Stock boot.img and recovery.image from B107
-booted to recovery and force update to B120cn
-reboot to B120cn
-reboot to recovery and do a factory reset
-check system partition size = bad, now only 750MB
-reboot and force update B132
-reboot to B132
-reboot to recovery and do factory reset
-reboot and check system partition size = Huraaa
, 1,5Gb System Rom are Back
Now i will install B507 over local Update and hope the size will not change again.
After go to B507 via LocalUpdate from System the System partition size is back to 1,02Gb.
But now after factory reset in B507 Recovery the loosing 500Mb come back. I`m lucky.
PS: Why TWRP, local update or force update will not set the correct partition size?
