Backup and Other Important Tips

Done with the USB drivers? Perfect. The tutorial is on the next page, but first, please take a look at the following tips and important points you need to take care of. These are important, as we don’t want anyone losing their personal data or apps:

Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. See below for some tips on how to backup data:

Samsung users can also back up data using Samsung KIES. If you backup data manually, you get more options what to choose from and it is very easy to move data across Android devices from different manufacturers, i.e moving Samsung Galaxy Note backup data to HTC One X.

If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up.

A few more optional tips that you should remember:

1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich and Jelly Bean.

2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?

4. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend NOT to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.

All set and ready? Good. You can now head over to the next page and update Galaxy S2 I9100 to XWLSD Android 4.1.2 Jelly Bean official stock firmware.

    new_to_odin: You only had one file then? Right?
    I’m not getting it to work. Getting some error in odin during md5-checksum and then nothing happens…

    • new_to_odin

      the zip file that got downloaded :


      size : 578, 818, 446 byes

      when i extracted it, there are TWO files in it:


      size: 934, 850, 637 bytes



      size : 276, 480 bytes

      your download is corrupted. you need to download the file again. that’s why it fails at
      md5-checksum. it was checking file integrity

    Hello! I updated Jelly Bean today following your guide. My Phone is GT-I9100, and I flashed this file in Odin and everything worked perfectly. After messing around with my phone, restoring all contacts from SIM-card etc. I found out that Gallery wasn’t working.

    It opens, crashes and then tells me that “There is not enough space.” and that I should remove stuff.

    Now after that I went to My Files to do some cleaning and I deleted few photos and pictures, although I had more than 5 Gb of free space. After I selected the photos and chose to delete, a pop up just said that (x) Files deleted. But nothing really happened, the files did stay there.

    Then I plugged my phone to PC and started up Samsung Kies, and it found all the stuff from SD-Card. I tried deleting those but again, nothing really happened. Pressing the trash bin button on Kies just basically un-checked the selections of pictures. “Now that’s odd” I thought.

    After that I went to your rooting guide and rooted my phone with Siyah Kernel. The rooting apparently worked (the Root Checker APP congratulates me with succesfully rooting my phone) and the SuperSU and CWM apps are there.

    Now then I was ready to wipe my SD card clean from all the data, and booted up the phone in recovery mode. It booted up and there was the “format External memory” option, what I chose, and it asked me that “Do you want to wipe the SDCard0”. I chose yes, and it succeeded in less than a second. But on the event log it said that SDCard error.

    I’m pretty clueless what to do. It seems like I have lost all my “write” privileges on my SD card and only have the “read” ones, or something like that. If you could point out whats going on I would REALLY appreciate it.

    My Galazy2 did an auto update to the 4.1.2 and now I am having issues with the touchwiz saying it has stopped working. After spending hours messing with the phone, I can go to settings choose the home page options and switch to easy mode and the touchwiz message will go away. But I want to use the basic mode. How can I fix the touchwiz stopped working message?
    Any suggestions 🙂
