Need help going back to stock - Galaxy S III Q&A, Help & Troubleshooting

As easy as it is I need help due to the fact that I have the I9300XXEMG4 firmware, the firmware that messes with the efs folder. I want to go to a recent, stock 4.4 state but I don't know what to go to due to the fact that I remember when I flashed another firmware a few months back, I couldn't make any calls or receive them due to the efs issues.
I would appreciate it if someone could provide the steps that I should take in order to get back to stock.
I'm currently running Cyanogenmod Mod 11 and I have been for a very long while now, I was on 10.2 and 10 prior to that and.
Thanks in advance.

Hi, if you are doing OTA it will be 4.2.2 or 4.2.3 at best, you will loose root, but not files or data.
Some apps may stop working or work differently, nothing to worry about.
Thanks and hows that? Major improvements? Something always weird with this one was the greenish tint when shooting with the flash... Is that fixed?
And there is a new chainfire's root out there i guess....
Thanks

Just want to say this isn't correct. Don't know if it's mistyped or something else, but it should be 4.1.2 'at best'.
Last official (thus OTA available) update for S2 will be 4.1.2. Sad as it is, for today's standards it is still acceptable.
what do you guys think about the 4.3 like sentinel rom?

4.1.2 is the latest (and last) official Samsung update. There are 4.2 and 4.3 roms available, but those are custom ones.

Yes i was wrong, long time didn't have to use stock.
As for ROM selection, try PAC rom, (latest nightly 4.3.1) I am really happy with this rom as my dd.
thanks guys, I am about to upgrade, just a question, can I use the OTA update even if my phone is already rooted and I have Siyah kernel on? is it going to break or get stuck?

The OTA will probably fail.....the OTA package looks for a stock setup, and if you've modified that setup in any way (custom kernel) the OTA won't install.....even if it *didn't* fail, the kernel would be overwritten and you'd lose root.
If it were me, I'd make use of chainfires mobile odin, download a jb firmware from sammobile and update that way......

I just downloaded mobile odin + last firmware like you said, from Samsung Mobile and it's now crunching

Did you enable the 'ever root' option in mobile Odin?
If not, you'll have to root the phone afterwards (if you want to)
A good place to start is the PhilZ kernel (rooted stock kernel + touch cwm)

cheers, actually no ever root since I used the lite version eh eh... I just rooted with this method w/ Siyah Kernel. worked like a Charm... now I guess I will be busy customizing it.. it seems much faster between home screens I have to say!
thanks again for the help
Gab
Yeah....I guess that's 'project butter' or whatever it's called....it's supposed to give an overall smoother performance........
If you are going to stay with stock, my advice would be to 'de bloat' it.....I used Titanium Backup to freeze the bloat first, then delete it after I'd found out that it wasn't needed/critical for the phone to run.......

The thing that I hate the most on stock rom is that it drains battery too fast
...still testing it..

The IMEI is your device's fingerprint number, flashing roms don't change it, unless the rom file is corrupted or some error happens during the flash, what is kind of rare.
You should be able to flash without problems, but don't forget to flash the correct rom version for your device, and to flash GAPPS after flashing the rom.
Hey
In addition I would strongly recommend to back up ur efs..

that's actually downgrading rather than upgrading. 4.1.2 builds are newer and use a new EFS format but the 4.2.2 builds are older and use older EFS format! so back up your EFS every time before you flash something as already mentioned above. if you face any problems refer to the link under my signature and post there for any queries.

When I always try to update to stock ROM UK Orange it updates but i lose my imei and no network connection.
I'm in JB 4.1.2 stock ROM rooted and everything is fine but when i update i lose imei.

Your efs folder is corrupt, pay for a repair or use a patched modem and kernel in 4.3

its not corrupted because everything is fine in JB 4.1.2 And I tried to use another modem and kernel in 4.3 but it didn't work
I get that update but when i update something happens if i backup my efs then if i restore would it work.
If you don't like the answer then fix it yourself, best of luck.
Dude your answer is not good, its not my fault

Do you know if your s3 ever had imei issues, got unlocked through means other than imei code, or did you ever used patched modem (or ariza)?
If yes, stay on 4.1.2, or do as adviced and get a patched modem and kernel for 4.3.
Your efs might be damaged, to stay on the safe side, backup everything before attempting to upgrade or patch stuff.
Ok thanks so do you mean by downloading another modem for my 4.3

If you want a custom jb ROM working fine in WiFi and signal, install shostock3 v4.0 or if you want come back to stock use Odin and install the last stock firmware I777UCMD8

If you have SGH-I747 as your signature indicates, then you are in the wrong forum. If so, disregard the advice above, and go to the correct forum for your phone.

[Q] help? I can't find out my stock firmware

Hello I own a Samsung galaxy SIII GT i9300 running nightly build PAC man ROM 4.4.4. I deleted my stock backup on cwm thinking that I wouldn't need it but I'm getting a upgrade to the LTE version (GT i9305) now and I can't find out which model I am for stock firmware to sell this on, it doesn't say in settings and dialer doesn't work, and I need stock to sell this on. Is there a working ROM on all international's? I'm a noob at this so sorry if this is already answered or its a stupid question
EDIT:I know how to go to stock but don't know which firmware is right. also build number in settings says PAC man ROM nightly then numbers..
Thanks in advance!

Follow the guide in sticky thread, download the latest stock firmware for your country at sammobile.com
It doesn't matter what version your original firmware was, just make sure it is for the i9300.
Everyone says it does but okay thanks if it works
