[Q] How do I fully refresh and deep clean my SGS4 ?
I have done some serious criss cross flashing /modem/rom/recovery etc. (Rom upon rom) over the last months. I've recently had a soft brick and had to reinstall stock. I want a fresh start.
I feel like my phone's memory has been rewritten many times by now and that there are some resedues (crap files) in the system that I can't get out and that are slowing the system down. I'd like to do a full blown erase and restore to factory settings and then set up my custom roms again.
What is the best way to do this?
I am familiar with the use of Odin etc.
It would be delicious to get full instructions from you.
