How to flash SlimBean final ROM on your phone

  1. The phone will have to be connected to your notebook with its USB cord. Once the devices are plugged to one another, you need to take both zip files from the laptop and move them to the phone’s SD card root, then unplug your I535 from the PC.
  2. Switch the device off and enter it in Recovery Mode by following these few steps: press and hold Home + Volume Up+ Power at the same time; when the logo of the phone’s manufacturer comes on, you need to release the 3 keys for a short while, then hold them once more.
  3. As you may know by now, there are some tasks of system wiping which must be done for an update tutorial. So here you go: choose “Factory Reset/Wipe Data” and confirm it; then return to the Recovery Menu, opt for “Wipe Cache Partition” and then for “Wipe Dalvik Cache“.
  4. Now choose the following few options: “Install zip from SD card” followed closely by “Choose zip from SD card“. Once you have done the previous tasks, you should continue by going to the update zip file. Then press “Power” so that it is chosen; right after that you will need to confirm the flashing of the file on your Samsung I535.
  5. That is all, the Jelly Bean 4.2.2 SlimBean Build 8 custom ROM shall be on your phone. Then you will have to also flash the Google Apps on the same handset; to make it possible, you should repeat the actions performed for the installation of the previously mentioned zip file. Go back to the Recovery Menu of your phone for the next couple of steps.
  6. While you are in that specific location, you should opt for the handset’s restarting option; after you’ve chosen the “Restart” option as mentioned, the device is going to reboot into the necessary firmware. The “About Phone” is where you will find the tool.

NOTE: There are quite a couple of problems that may need a quick solution. If, say, you come across “Status 7 error” on the touchscreen of your phone, you have to first flash a related kernel; second: flash the custom ROM archive on the device.

But, if you cannot get unstuck from a boot loop, you should, before your reboot the handset, take the following route: perform a “Wipe Cache Partition” and then a “Wipe Dalvik Cache” a couple of times.

After you play around with the new firmware, you may want to regain the old ROM. For that, you have to boot the device into the Recovery again, then opt for “Backup&Restore“; now wait for a list. When you spot the latter, look for the ROM and choose it to have it back on your Galaxy S3 I535 from Verizon Wireless.
