Fixed ROM Setup File error ‘updater process ended with error 6

I have edited updater-script file. If you don’t edit it you will faced error “updater process ended with error 6” . The problem is in line 16 ‘ui_print(“——————————————————--);’ change it to ‘ui_print(“——————————————————--“);’.  Repack it to zip file using 7-zip recommended.

  1. Enter TWRP Recovery Mode: Turn power off; Press and hold Volume Up key + Power key, when samsung logo appears release power key only, keep pressing volume up until TWRP recovery appears
  2. Select Wipe – Format Data – type “yes” and confirm
  3. Select Wipe – Advanced ( Dalvik, Cache, System ) Swipe to wipe
  4. Select Install ( If rom file in SD Card: Select Storage – Micro SD card – OK ) – select 「 InfinityOS A30 v3 」.zip, Swipe to confirm Flash, Be patient it takes more times..
  5. Select Reboot – System
  6. Setup the phone
  7. Done!

Rooting if necessary

  1. Connect the phone to Internet wait for a moment.
  2. Install Magisk Manager. Magisk Manager will ask to do additional setups. Let it do its job and the app will automatically reboot your device.
  3. Done!

If you want to uninstall this custom ROM and back to stock ROM, just flash the stock ROM to your device. Flashing stock ROM will also uninstall TWRP Recovery and it will back to stock Android Recovery.

Notes / Warning!

  1. Use at your own risk, I’m not responsible for bricking your device.
  2. Using the incorrect file may brick your device.
  3. If your target device has a custom firmware flash counter, Rooting will trigger it. If you’re lucky, Triangle Away has support for your device and can be used to reset the counter.
  4. If you have a KNOX-enabled device, flash custom rom and Rooting will trip the KNOX WARRANTY VOID status!
  5. If your device storage is encrypted, Rooting will wipe your data !
  6. If you have locked bootloaders, flashing one of these will probably brick your device – with the exception of Nexus devices, which will usually automatically “OEM unlock” and wipe your data !
  7. Make sure to backup your important data before root it.
