This is a simple fix I'm sure, however Im new to all this. Just bought a used LG Optimus S, already rooted. Dont see the market in my apps however, and just wanting to know how to go about getting it back!
Download the apk to your phone and open with Astro File Manager to install it.
Instructions:
1. Download the new android market application’s .apk file.
2. If you downloaded the file on PC, transfer it to phone.
3. On phone, enable non-market apk installation. Go to Settings – Applications – tick the “Unknown Sources” checkbox at the very top. Accept the warning which pops up by tapping on OK.
4. Open the file explorer (if you don’t have one, download any file manager from the android market) and browse to the location where you’d downloaded/transferred the file on phone.
5. Tap on the file to install it. This will replace your existing market app. Select OK when asked during installation.
