I was wondering if not using a computer to download & flash new ROMS will cause problems with either the ROM or my phone. I used my laptop to root my GS3, but shortly after my laptop quit on me. So I started to just download a ROM straight to my phone using the phone. Every ROM I've used I've done this way. Right now I'm running CM11 & android 4.4.2, the reason I ask is I haven't seen anyone doing it like that. In all of the instruction sets for the ROMS they all use a computer to download & put the ROM on the phones SD card. Now I haven't had any problems with any of the ROMs I've used. I did have some files that wouldn't flash. I do wonder if some features or something doesn't work, but I don't think I've had that problem. So anyways, is there a up or downside to using a computer or not using one?? Any input on this subject is greatly appreciated....
