My Note 2 used to work fine on 4.1.1 and 4.1.2, stock and unrooted.
Then I rooted and flashed a 4.2.2 ROM (I think this ROM was banned from xda, so I'm not going to mention its name). It ran fine on this ROM, except for some hiccups inevitable for a custom ROM. I even upgraded this ROM a couple of times with no issues.
Then I made a stupid mistake. Before upgrading my 4.2.2 ROM again, I decided to factory reset, wipe cache, dalvik, and "Clean to install new system" in PhilZ Touch CWM. I then flashed the ROM and ended up with a boot loop. So I used Odin to flash the latest stock ROM for my country and operator.
Then the freezing started. Sometimes also reboots, but mostly freezing.
There is no pattern to it, it freezes when I'm on the lockscreen, opening an app, swiping through homescreens, using maps, taking photos...
Sometimes it freezes ten times a day, some days it doesn't freeze at all.
I have done multiple factory resets, I have reflashed the stock ROM, rerooted and flashed the 4.2.2 ROM again to no avail. It's only a matter of hours before it freezes again, even with no extra apps installed.
eMMC check says I have the insane chip, but it passes the sector test and Dummy File Generator didn't freeze my phone either.
What do you think it could be? Could this be early symptoms of SDS?
