Help Can JB 4.1.1 be reversed to ICS on S3 unrooted

[AnoTherS3uSer]

Hi, i recently "updated" my phone to Jellybean 4.1.1 and ever since, my battery life is less than 24hrs. phone is basically new. never had any problems before with ICS. In fact there are things i also dont like about the update but thats subjective so what evs...
I have already disabled Google Now, so its not that (but thanks for guessing that off the bat!) Checked power saving mode etc.
Anyone know what my next step will be for getting my awesome phone back?

Have you tried a factory reset? Relevant post by SUroot here: http://androidforums.com/samsung-galaxy-s3/659933-problems-after-upgrade-factory-reset.html

On stock 4.1.1 & 4.1.2 I was getting about 36 hours out of moderate use, so it's not 4.1.1 or 4.1.2 causing it.

Factory resets won't get him back to ICS.

However, dirty caches are the cause of 95% of the problems I see people having after taking an ota. If you are unrooted,performing a factory reset is one of the few good ways to clear it.

No, but as described in the thread I linked to, it's a good start for these common problems. Also a lot less drastic than rooting and flashing an ICS ROM!

thanks for the info, i might try factory reset and see if these 'dirty caches' can be fixed... So there is no reversal possible to ICS?

Not without rooting the phone and selecting a ICS rom.

Wait, your S3 doesn't have rewind?

did factory reset fixed the issue??

Its easy to install a stock ROM with or without root. And yes, you can reverse to ICS. What is your phones version?

Hi, I'm not sure if I can help here or not, but I'll try...I have the SGS2 and I did the same thing..I had Gingerbread on it and updated it to ICS and had similar issues...I cleared the cache and factory reset many times..still having some issues...so I used a program called Odin5 and went to Samsung and downloaded the ROM's for my specific phone. You can go to this site and get everything you need. http://androidforums.com/551-all-things-root/480888-odin-stock-rom-tutorial.html

I reverted back to Gingerbread 2.3.6....and has been working like a charm...

I'm thinking about giving my SGS2 to my mother-in-law and I get myself the SGS3....any pros and cons about this phone?

I have T-Mobile...

If it's the GT-I9300 then you should be able to just flash a firmware through odin without much problem and definitely no need to root. Unsure about some of the carrier versions. Maybe try a reset and clear the system out
