I recently downloaded LoL and I've had some issues on the "step 2/2 updating league of legends" causing me to (still) not being able to get in. The KBPS keeps dropping to 0 and won't go back up, even after hours. I've looked around the Internet, but nothing seems to work.
A lot of these are going to be super simple, but may as well try 'em. They're in the order I reccomend doing them in. Note that you can do many at the same time.:
- Are you installing from the same file each time? If so, download a new installer.
- Restart your PC
- Run installer as Admin
- Enable / Disable P2P: In your client, click the gear icon in the top-right, and then check or uncheck "Enable Peer to Peer Transfer":
- Close out all other unneeded programs -- like, all of them
- I don't know how you're uninstalling League, but try doing it with a free trial of Revo Uninstaller. Then reinstall.
- Contact League support
Again, you have probably tried many of these already; sorry if this answer is redudant.
