Start at the farther most bleed screw then work toward the closest one. You may also need to bench bleed the master before installing it. Which mean pull master cylinder back off to bench bleed it then reinstall it, then bleed the right rear, then left rear, then passenger side front, then drivers front. May be better off also using a bleed tool pump. Make sure all bleed screws are tight (not over-tightened just closed off) before moving to the next one. Keep the master cylinder with brake fluid in it to not let it empty or you need to start over if it empties.
How do i turn off the ets off light? And souls i replace the break booster?

'ETS-OFF' (Electronic Traction System Off), Check for Bad fuse(s) or bad ETS module. Make sure E-brake is fully dis-engaged. Also comes on when gear selector is in 2nd gear position or spinning the tires. Have the computer scanned for additional codes. Look for it being dis-connected or bad connection(s) or wires,may need connector cleaned with circuit board cleaner and then add dielectric (bulb) grease inside connector, it works in via with the ABS system. ABS sensors could be issue. I do not believe the brake booster is connected to your issue. But he brake booster can be tested. The primary indicator of a faulty brake booster is a stiff brake pedal.
