OK so before i start I want to say that I have been researching and cant find the specific answer to my ?'s. That being said... I installed rom manager and selected the back up current rom option. It gives me the date as a save file and I hit ok. It then reboots and asks what I want to do. I select reboot system like normal. Then I go back in to check it and it doesnt have the file for me to view, kind of like its not saved, or it really isnt saved... idk for sure. I would like to install the JT1134 rom w/ the lag fix but I want to make sure I do it right as to not mess my phone up for good. Is there a dummy's guide for this? I read everything I could find on this. Plus in the rom manager it has the download section for the JT1134 rom... can i just dl it from there and it installs it for me? Sorry to be dumb... just being cautios. This is what it tells me...
