Hi, I recently bought a Samsung Galaxy Ace S5830 from Ebay and it came with android version 2.3.2. I tried every way of updating the firmware with no success as I was unable to install any apps on the phone. I have recently downloaded a update file for android 4.1.1 or something along those lines anyway I applied the update via SD card and now the phone will not boot up. I am struggling to find a suitable SD card update file as this is an old phone, I would be happy just to upate the android version to latest version suitable for this phone (2.3.6 or 2.3.7 seems to be mentioned on other sites). Would really appreciate it if anyone was able to supply an update file for a suitable version of android for this phone that I could copy and install from an SD card as I cannot get my phone to work at all currently. All help appreciated. Kev.
