Instructions

  1. Your number one duty for now: plug the handset to the laptop. Move on with the next step that tells you the following: go to the two files, take them from there and move them to the SD card of your Galaxy S2 Skyrocket.
  2. After that, unplug the devices from one another and just make sure that your phone is switched up for the next step which consists of the following task: boot the device in Recovery Mode via the steps from this tutorial.
  3. Should you have missed the chance of making a NANDroid backup, now’s the time to do it. But be careful, because this process depends on the type of custom recovery your smartphone has in use. For the TWRP one, you need to tap “Backup” and confirm the process after you choose all of those files you want backed up; to make a full NANDroid backup if your device uses the CWM instead, you will be asked to start by choosing Backup & Restore, making the backup file and then saving it to the SD card root.
  4. Now you will be required to apply a Factory reset. If the phone runs CWM, you need to opt for Factory Reset/Wipe Data and continue by confirming the action. To apply this Factory reset on a TWRP S2 Skyrocket, you will need to tap “Wipe“, make use of the option called “Factory reset” and then confirm.
  5. In order to ensure the presence of the new firmware on your TWRP device, you should tap “Install” first; after that: load the firmware into the custom recovery and confirm the flashing. To flash the file in case your smartphone uses CWM, we advise you to opt for these before you confirm the installation: Install zip from SD card and for Choose zip from SD card. To have the Gapps flashed, too, you need to repeat the steps which got you the new ROM on your device.
  6. Now that the files are on the Skyrocket I727, you can go to the Recovery screen and restart the phone. The SlimBean JB 4.3 build custom ROM is now on your handset at long last. The NANDroid backup you made not too long ago will be of help if the ROM doesn’t sit right with you.
