Downgrading S3 From JB to ICS ! - Galaxy S III Q&A, Help & Troubleshooting

I recieved the Jellybean update earlier this week and i'm not happy with it. It has slowed my phone to a great extent.
Is it possible to downgrade from Jellybean to ICS w/o ROOT ?

Flash odin with ICS firmware from sammob

Won't the ICS Stock Rom provided in S3 Android Devplmnt Forum of XDA Suffice ?

4.0.4 Odim rom?

I´ve had some bad and scary experiences trying to move my GS2 from Illusion-ICS v1.0.1 XXLPB-I9100 (kernel 3.0.15-XXLPB-CL99600) to ICS 4.0.4 via CWM.
Can anyone point me to an Odin flashable ICS 4.0.4 compatible with my current rom?
thanks in advance
number of roms in dev section ,see which fits u...
I´ve been browsing for ages but they all seem to be CWM.
You are going to have to read every single rom post to find an Odin flash if their is such a custom rom ..
100 CWM flashed today no problem .
4-04 rom do you mean non Samsung rom as 4-04 is not a Samsung release .

Samsung did to start rolling out the 4.0.4 ICS.

I don't know where you get your information... latest Samsung stock firmwares are 4.0.3 still.
As of right now, the only 4.0.4 firmwares are AOSP or AOKP.
Cm9 got a special Odin ROM for people like you.

Just flash any ics rom in odin
I advise 4.0.3 LPG. Current 4.0.4 ROMs are still immature and new releases for wide Europe will come soon

Either root your device with CF root and flash custom roms, or go to www.sammobile.com and download a stock firmware and flash through odin if you want stock ICS

DOES the 4.0.4 have any issues ? or any bugs ?
If your already on ics.then use the link in second post(phil)
if u are on gingerbread and want to upgrade then u need to upgrade bootloader and to be sure the rom contains bootloader,go to samfirmware.com,register and follow instructions
No not really. No annoying issues

YES i am currently on Gingerbread.I just bought it 3 days ago.......How can i check if ROM contains bootloader ?
ICS is great imo, Just root your phone and then follow the instructions on the rom's thread.

Mate....you REALLY need to do some searching and reading before you touch your phone.
You ask for 4.2.2 firmware.....it doesn't exist....4.1.2 firmware is the newest.
You can get newer versions of android in custom ROMs.....but....
SEARCH READ UNDERSTAND LEARN......THEN AND ONLY THEN...DO......
some search suggestions.....
emmc brickbug
Odin flashing
kernel
Rooting
Firmware
custom ROM
Knowledge will help to prevent you from turning your S2 into an expensive paperweight. It's no good providing links unless you know/understand what you're doing......

Flashing roms in CWM is same in all phones...
If you looking for an AOSP roms, you can try SlimBeans... I use it and its really smooth and fast and low battry drain
If you Looking for Samsung base Roms, Try Wanam Lite or Android Revolution HD...
there is lots of note 3 ported roms but i found most of them laggy and unstable...

I have flashed lots of official roms, but i didn't see any important differences between different countries roms... Just some language features...
I'm persian but i flashed MK6 rom that is for Europe, I've got no problem... I can even type Persian...
For 4.3 rom, you've got just few choices and best of them is MK6... The other 4.3 updates have a lots of bugs but MK6 is almost bug free rom...

ICS is not really a very good rom and I would recommend KK or JB
you should be good if you go from a GB firmware to a JB one
or if u want you could flash a custom kernel in odin and then flash a KK ROM like CM11 or Slimkat

can you give me some safe Rom that i can flash to my phone? or links?.
I'm searching but im afraid to use other ROm aside from GB.
thanks again Toby..

It`s very safe to flash Jellybean or Kitkat. Download the latest jellybean from sammobile and flash it with odin.. Look around for tutorials how to. Note that you will lose all your data, but your phone will 100% work. That brickbug was only on 4.0.4 version.. To be sure and safe flash jellybean and after that flash PhilZ-cwm6 - Safe Stock Based Kernel. If you need more info, i`ll help you. Cheers!:good:
