I bought this phone from USA and it is designed to AT&T by Samsung. It was unlocked and was running with Android 2.1 ( Eclair ). Once I bring back to Sri Lanka powered it on and it was working fine until I charged it after which it was dead. Then I bough another phone and get it down here and replaced the motherboard. Then it worked. It was like this initially.
I wanted to upgrade it to Android 2.3 ( Gingerbread) , then root, then install the latest custom ROM.
First I downladed Samsung Kias Mini and connected to the phone and checked the latest upgrade and it is Gingerbread of course.
It is pretty easy and Kies Mini will just push the upgrade and finally restareting the phone will boot in to Ginger bread. Then first I needed to root this phone- for which I needed to download below files.
This includes ,
1. Clock work mod recovery ( CWM)
3. Corn Kernel
First connect install Odin and then connect the phone to USB cable and then press volume +/- signs together with power on/off button. The phone will force on to download mode and the communication port will be identified by Odin.Then Select corn-kernel ...tar file and flash it to the phone and install CWM recovery.
Once it is done, the phone is rooted and CWM is installed. Then I found a custom ROM that suites to the phone. It was based on Jelly Bean 4.1.2 and one smart Engineer has tweaked the code to match to captivate. First this is how the CWM screen looks like.
This is ROM I downloaded .
Then I put this ROM file in to SD card and then select the option "Install ZIP file from SD card"
Once it is done , installing the custom ROM started. This process is critical, and need lot of care.
Thanks for Reading..
