I9100XXLP6 is pretty good and stable firmware. The major bug with this firmware was GPS fixing issue. Thanks to our developer community XDA, you can easily fix GPS bus on I9100XXLP6 firmware in 2 minutes. Follow the instructions below.
** Please install official ICS I9100XXLPQ which doesn't have these bugs **
You need a rooted device for this procedure. Please check I9100XXLP6 rooting guide.

You are done ... You will be able to use GPS now :) Check screen shot below..

ReplyDeleteflash cf-root kernel. root with odinmobile doesn´t match. then fix gps. works here for me
Got the GPS to work but shows the yellow triangle at start up although that doesn't bother me much...
ReplyDeletefollow these steps, this flashes the recovery but not the ROM so you wont loose any data. http://www.dialandroid.com/2012/01/root-i9100xxlp6-android-ics-403-galaxy.html
