I've been going down rabbit holes looking for a definitive solution or answer to the issue of downgrading my 4.3 i535 on Verizon back down to 4.1.2. I don't particularly care about actually rooting the phone (would be nice but not necessary). I'm having no end of Bluetooth and audio-when-docked issues with my phone that were never there on 4.1.2 and would desperately like to (a) revert back and (b) somehow tell the phone to never do an OTA software upgrade again.
I am not really all that technically adept, although I can follow instructions fairly well--provided they're valid for my device at the current time. I have never attempted any sort procedure like this and I'm usually quite content to be a good little sheep and do what I'm told by Verizon/Sammy. But when I can no longer reliably pair my device with my Alpine aftermarket car audio system, nor have it properly play back audio directions when using navigation software like Waze or Google Maps through the BT-attached speakers, then I need to do whatever it takes to re-enable this lost functionality.
Any directions or comments greatly accepted. Again, please, I respectfully ask that if there's anything that can be done, that a kind soul here would post directions for a complete n00b, not an experienced phone expert. Frankly, if there were shops near me that I could bring it to to have done, I'd have done so already <grin>. Many thanks in advance.
