I have a Galaxy S plus (GT I9001), I installed Tiger Jelly Bean recently, which was working fine. But phone was lagging a lot so I decided to install the stock rom again. I installed Kies(latest version) with drivers and connected my phone to my PC, but it was not detected by Odin. Every time I got Samsung Composite USB Device driver installation failed. So I searched and installed drivers from Here and Here . But they didn't worked either. I tried again after changing USB Cable but still no luck. Then I installed Kies in my Laptop and tried to connect the phone. Still it wasn't recognized.
Things were not working with downloading mode and Stock rom tar file cannot be flashed with recovery mode. So I searched a converter for .tar to flash able .zip file and found THIS. I installed this tool and tried to convert the tar file to zip. Didn't noticed that it require knowing "Mount Point", so I converted the tar file to zip without changing the mount point and copied the file to internal storage of phone and flashed the zip file. After that phone restarted , and stuck at Samsung Logo.
New I can't even to recovery Mode, nothing happens when I keep Pressing Vol Up + Power. Phone starts and stuck at samsung logo. Odin was already not detecting the phone so I tried connecting the phone on Ramdump Mode and some how drivers were installed and odin detected it correctly. But odin can't flash phone in ramdump mode so it didn't worked.
So now the problems I am facing are: 1- Phone is stuck at samsung logo, can't go in recovery mode. 2- Odin not detecting phone in downloading mode.
Is there something what I can do to fix this? Please help!
