    Default Galaxy S2 official downgrade from ICS to GB

    Hello everyone,

    I stupidly did the same mistake again by updating my S2 from GingerBread to IceCreamSandwitch without calibrating the horizontal accelerometere, and now unfortanatly i cannot find the official GB firmware for my S2 .
    Anyone could help me about that please ?
    (if you have a better solution that will fix my accelerometer i will really appreaciate it cause now when i play games like " Trial ", when the phone is in the "normal" position the rider is always going back so i have to rotate the phone about 15 degrees to the right in order to be "normal" )

    thank you

    Have you looked at Samsung updates .com? A big problem with a lot of the site that have ROM libraries is they used Hotfile, which shut down a few months ago. These sites are now frantically rebuilding their libraries.

    nothing either...
    PS :
    is it really impossible to recalibrate the accelerometer on Android 4.1.2 ?
    i am 100% sure that it's not a hardware problem so why there is no way to fix that :/ ??

    I found something that has the stock firmwares. A few of them are 2.3.x ROMs, but they vary by country. Good luck

    [ROM/KERNEL/MODEM] GT-I9100 - Latest Stock Firmwares - Direct Links - Torrents - xda-developers

    Sent from my Galaxy S4 running SlimKat 4.4.2
    Unfortanatly the links i checked are offline plus the OP is suspended from XDA so i cannot trust his links, the good news is that i found this website : AndroidFirmwares.net - News and am downloading this firmware the bad news is that i have no idea where to find the .pit file any help please ?

    UPDATE :
    Thank you very much, changing the cable solved the issue below this, the phone is back to stock again using links i mentioned above (i just needed the firmware file into the PDA section of Odin)
    just in case someone face this,
    i got a SplashScreen loop (my SplashScreen is changed from TIM {italian operator} to the default samsung wich is another victory for me )
    anyway,
    that was simply solved by booting into recovery mode and wipe all data

    another problem is that Samsung Kies doesn't detect new update anymore, i think that is because i only used PDA in Odine ?
    i'll have to update with Odine again (it take less time than kies anyway...) but if you know the reason why please share with me

    EDIT:
    it seems that i only need to select the downloaded firmware from the PDA button and press start in Odin so i tried that and i got this error :
    "Can't open the serial(COM) port."

    And since kies is completely closed and am 100% that i have the USB direver installed (phone detected and i've done that before)
    i am going to assume that my cable or my ports are the cause of the problem, if you have a better suggestion please illuminate me, otherwise i'll try with different cable/PC tonight and keep you updated, lastly i REALLY hope that an expert android developer or maybe someone that can spread this problem for more people cause it is VERY annoying to have to do this for such a minor problem just because the OS developers have forgot or didn't want to allow us to adjust all the phone sensors ...
    Note that after this downgrade, i will have to upgrade again and restore all my previous data,setting, apps again... and that is a real painful waste of time >_< !!!

    thank you
