    Hi there,

    I've ordered my n5 and so am preparing to sell my SGS2. It's currently rooted, on the stock firmware (I've done OTA updates since I got it new, so it has never had a custom ROM). I rooted it about 6 months ago, by flashing the Jeebo kernel following this guide. I now want to completely clean the device in order to sell it, but am a novice with Android, so am not totally sure how to do this correctly.

    From what I can gather from sources such as:



    and this, I need to download my stock ROM and flash using Odin.

    As I stated in the title, the phone is locked to O2 (UK) and is the 16GB black model (if that makes any difference). I checked the CSC which is 'I9100XEULS5' and the PDA which is 'I9100XWLSW' and gather that I need the corresponding file from here (I have started downloading 'XEU-I9100XWLSW-20130530173418.zip', is that the right one?). My confusion is also coming from the fact that my device is locked- on the blog post I linked, people in the comments were mentioning needing unlock codes after following the guide... I was wondering whether it would be best to just unroot by flashing a new kernel or using the 'OTA RootKeeper' method which I have seen elsewhere, but am not sure if this is the way to do it.

    Can someone please point me in the right direction?

    Thanks,

    Dan

    Go to the samsung website , there should be a android downgrade update. Put it in your sd card and go to recovery mode and flash it . It should be running a lower version of android but then a ota notification should appear . There'll be no signs of root . Good Luck ! Hope it works

    OK, can you help me find it? I had a look on the samsung website but couldn't find the downgrade update thing . Also will this definitely work on a SIM locked phone?

    I've had a look around on here and XDA, and it looks like my phone is unbranded (it is, however, sim locked to o2 uk). As I said I downloaded this: XEU-I9100XWLSW-20130530173418.zip' but now I'm thinking I need this: 'I9100XWLSW_I9100XEULS5_XEU.zip'. On XDA, the info next to this ROM states:

    Base Firmware: I9100XWLSW (4.1.2)
    Region: Europe
    Country United Kingdom
    Carrier: Unbranded
    Build Date: 15 May 2013
    Modem: XXMS2
    CSC: XEULS5
    Change List: 1211311

    My modem, CSC and phone all match up with that, so I'm assuming this is what I need to flash, not the one I originally posted
