Like many, I am extremely disappointed with Samsung's attempt to bring 4.3 to the S3 and am on the verge of switching to CM 10.2 from a stock ROM. The ROM is rooted with a yank555 kernel and philZ recovery.
However, upon reading this forum; http://forum.xda-developers.com/showthread.php?t=2531221 and several others like it, I realised I may or may not run into an EFS or no network issue. I have the stable 10.2 and 4.3 Gapps ready to install via ROM Installer.
Is it only if the android version is downgraded that any form of EFS error could occur? As 10.2 is based off 4.3, I thought it would work fine and flash as it did when I ran stock 4.1.2 but wanted to double check.
Thanks for your time.

There are a lot of people joining xda on daily basis, and there are a lot of repetitive questions being asked which fill up Development threads. Point them here. Feel free to ask or answer questions. Idea of this thread is to get users to help other users with their problems/questions. Please do not spoon feed, but rather point in the direction where that user can find an answer and educate himself
I don't actually have the GS3 unfortunately, but in order to make XDA a better place, I thought I'd open up a help thread for those who need it. I won't be able to give S3 specific help, but I can help in terms of general questions. Hopefully some of the experienced S3 help out on this thread, because it'd make everything easier. Thanks!
First thing first. I strongly advise you to read THIS thread before posting ANYTHING on XDA.
Then, have a quick look at the names of threads in post no2, you might find what you need right away.
For ROM issues please do mention in your post about:
ROM name
ROM version and base
kernel version and its settings
any mods applied on top of it
flashing "style" aka dirty or clean
something like this
...and be sure you have asked before on the ROM thread unless you have less than 10 posts on XDA
Third. Even if you do get your question answered, please, do come back and read threads in post no2 (coming later as soon as we start getting the guides) to educate yourself. You'll be surprised how much time and frustration it will save you in the future.
ASK ANY QUESTION HERE,adb, drivers, superCID etc...... You will either get an answer or will get pointed in the right direction.
No abuse towards noobs tolerated here! No question is stupid in this thread.
***I feel that a little OT is healthy to the success of this type of thread. The people here who help the most will develop a comradery therefore OT is allowed within reason. Common sense will be applied ***

Stuck
Hey guys, i'm sort of a noob on these forums so any help would be great!
I've had previous experience with rooting because of my S2, no problems at all. I got my s3 about a month ago and I've been trying to figure out how to root it. It's a GT-I9300T ( Australian model ). It has a lot of Vodafone bloatware, however it's unlocked as i'm using an Optus sim card. I've also read that there aren't many differences between the international model and the T model, so any international ROM should work fine. It's running 4.3. I've read about how KNOX is built into 4.3 and makes rooting difficult by blocking the installation of custom Roms and disabling superSu. I'm not sure if i have Knox though, because i don't have a KNOX app installed; there are no KNOX related apps installed on my phone ( according to the all section of my applications manager ) and it says nothing about the KNOX counter in download mode. Is KNOX still present on my phone, and will i be able to install customs roms?
Also, what would be the best method of rooting? I have tried the saferoot method by Mrw0lf on YouTube, which is made not to trigger Knox. I've read about CF root and other methods involving Odin, have not tried any yet because i'm scared of bricking my phone. Any help or link would be helpful. Also, if something goes wrong; would i be able to flash a stock 4.3 ROM onto my phone using Odin? I'm downloading it now from sammobile and i was wondering if flashing anything through Odin would cause problems.
Lastly, is there a way to backup my EFs before rooting? I can't find them through the default file explorer and the folder is empty in 3rd party ones. I can't seem to find them when i go through my phone on my computer, i just want a backup before i try to root.
Anyway, vital phone info:
Model: GT-I9300T
Version: 4.3
Sorry for the long post, but any help would be cool. Also, i'm not that good with all the technical things behind rooting such as CSCs, basebands and such, so any simple explanation would be nice
Thank you! :fingers-crossed:
Good morning
Dont worry about knox
There no knox for S3 now matter what variant
Now secondly.
U can flash everything from i9300 on your i9300t however its advisable that when u flash roms that u maintain or re-flash afterwards the appropriate modem
As the only difference between models is the band frequency
To root it ... For myself the easyest way is ...
Grab philz recovery
Flash it with Odin
Afterward boot into recovery
Go to advanced and choose re-root system
Then just boot the ROM go to market and download supersu you're good to go
About backup efs there's a loooooot of apps to do so u just need the pick the one who's flavour suit u best
Take care
If u have doubts just pm me

Thanks for the reply!
I just rooted my phone using Cf auto root. I forgot the warranty was expired so why not It ended up working, now running CyanogenMod 11 nightly About the modem, the reception seems the same. The signal i got before I rooted wasn't that great, haha. But i'll probably flash the modem anyway, just in case. I found a thread with most of the modems for the s3 here:
http://forum.xda-developers.com/galaxy-s3/general/ref-galaxy-s3-modem-radio-collection-t1740061
All the modems are for jellybean, however the ROM i'm on ( CyanogenMod 11 ) is on kitkat. Can i flash any of those modems? For the T model, they say there's no regional or carrier specific one, even though i checked my modem on sammobile and it's not listed in the thread. The latest one is for 4.1.2, i'm on 4.4.2. Should i flash it? Also, can you flash it in CWM, or does it have to be through Odin?
Edit: Seeing as you're a fellow S3 user, have you experienced any lag or freezing with your phone? It happened quite a lot pre root, but i just thought it was due to the bloatware. And Touchwiz, haha. But it's happening with CyanogenMod 11 as well. I know that it's a nightly and that bugs are to be expected however i have an S2 running CyanogenMod 11 as well, and there's nowhere near as much lag. Any ideas? I reset the phone and re installed the ROM twice, mainly because i forgot to flash Gapps XD Any ideas? Should i do a full factory reset, free up some space? I know that there's 2gb left on both the phone and my SD card.
Anyway, thanks for all of your help so far!

If u flashed cm u have retained same modem so no need to update modem
Just leave it be.
About lag no my phone runs just good no matter what aosp or recent stock rom
Check your kernel config or go for a custom one a and set him up to what suits u best.
I use agni kernel on cm alongside with a optimised profile
And even with a UV of CPU and GPU my phone runs real smooth and saves juice

ive got experience with flashing custom roms and know how to do it but im quite paranoid which is why i have this question. Im currently running foxhound 2.4 on S# GT-i9300 with siyah kernel and i want to flash slimkat 4.4.2 build 3. i was just wondering if siyah kernel will get in the way of the flashing. Will i need to flash stock kernel then flash slimkat/gapps or does slimkat have install its own kernel in which case i guess i should just flash normally.

I think you should probably full wipe before flashing another rom. Then you should be good to go to flash slimkat and gapps.

SD Issues ? backwards "u"
My Wife is on her 2nd SD card with the same issues. I copy all of her pics and some videos from her move them to the Sd card. When going into my files it says there is 500+gbs on it! The file path extsdcard/Android has 467 gbs and 471 folders. Then there is a data folder but the D in data is a backwards u then ata. This folder says it is 467gbs with all folders named with crazy looking characters. I did try and search forums but could not find where to post and didn't want to get yelled at by the "Geniuses" on here for posting in the wrong place or not searching well enough. So if u could please get me to the right place it would be much appreciated. All the files are pics and vids of kids and thankfully we have auto backup in with google otherwise it seems we would lose all photos and vids. Thanks. Please see attached pics for reference
S3 4.0.4 stock rom
I had installed android 4.3 on s3 but then I installed 4.0.4 after that I had no gsm connectivity see the block sign between battery and wifi. I have gsm connectivity on 4.3 but not on 4.0.4. A guy told me that it has something to do with the bootloader. I wish to install 4.0.4 stock ICS BTU rom if there's a way do tell me. Thanks in anticipation!
i am using GlamourS4 5.0 rom and googy max2 kernel
the first problem i have is when i pressed the emergency call button on the lockscreen,
it did show anything such as the keyboard and the signal will stop a few seconds and come back.
second, i found the nfc not working anymore in my phone.
the nfc and s beam tag are greyed when i try to turn them on.
can anyone can solve my problems?
Anyone for my weird Network problem...?
I recently rooted my S3 via the CF Root method. Flashed CWM Recovery 6.0.4.4 via Odin.
That's it.
And now this weird problem-
My network is lost anytime! And the phone even doesn't say "Not registered on network" or something like that!
My phone was working properly and suddenly a friend of mine messaged me that he tried calling me but it said that my phone was switched off! I also noticed that at time even the data connection was not working. NO! It's not that it didn't show it isn't connected to the network or the data is disabled! The signal in the status bar was of 4 bars as it is and there was this symbol of 3G beside it. I tried calling my friend but the call got cancelled! I redialed, I didn't hear anything and then again the vibration saying the call was cancelled! I called up on my S3 through my landline number which also said that it was switched off -but not immediately. Whenever someone called me, they didn't hear anything for a long time of a minute or two and THEN it said that my mobile was switched off. I tried selecting my network operator manually, it said 'Registered on Network' but still I couldn't receive or make calls or use my internet data. But I could always send or receive SMSs!! It means it was connected to my network. The only solution was to reboot the phone after which it worked fine for a few hours. FOR FEW HOURS ONLY!
Now it happens at least 2-3 times per day and it has been important for me to check whether the data connection actually working and I'm able to access the internet or not because that's the only way to find whether someone can call me or not!
How do I fix this? I'm having my exams now and I don't have time to setup my phone again by changing ROMs!
Please tell me a way to fix this without changing my ROM!
I'm on Android 4.3 Stock ROM.

Google search question
Hello everyone.
I have noticed a strange behaviour of Google search after flashing SlimKat 3.9 and 3.10. Settings for search applications and contacts on the phone are gone. Is it a new update from Google or a bug? Fresh install didn't help. Screenshot attached.

Could be to do with the EFS partition. 4.3 uses a different version and apparently problems can occur when trying to revert to an earlier version. As far as I have read elsewhere, the problem can be verified by checking the IMEI number in settings - if it is all zeros it has been corrupted and will cause what you describe. I'm afraid I don't have a solution but hopefully this info might help you move a bit closer to one.
Another SlimKat question. According to battery stats, it seems that my wi-fi is always on. I've used 3g only since last charge and wi-fi is off in settings. Can it be helped somehow? Screenshot attached.

Hey Guys,
im crying, cause in my whole life I had never a problem which I cant solve. :crying:
The Story:
I started my phone and got a wounderful bootloop which forced me to flash a new firmware (firmware before: cyanogen mod 11)
I flashed a Stock Rom: Android 4.3 DBT and tried to backup before, but the clockworkmod recovery wont let me, it cancled at
the System Point.
So I have just a Backup with a uncompleted system tar (but which I can open with 7zip), a boot.img and a recovery.img.
NO esf.img. I did not know that the IMEI could get destroyed after a flash, so I thought it would be no problem if I flash anyway,
cause I had no other opportunity.
Now I'm googlin for like 3 Days and tried every possible Soultion, flashed again, flashed root, done the 9step fix,
done the hex fix, ... I think I did everything, but nothing worked. My only "success" was to get a 0049 IMEI.
Which is not really a success.
The Problem:
No IMEI, or just 0049 and *#1234# says that I have no IMEI Certificate.
What can I do? Is there any fix out there, which can help me or does life force me to give up the tons of hours I lost for
this **** and send it to a repair service? Can I send it then to Samsung repair service?
Thanks in advance for any help.
Btw.: Sorry for the bad english, it is not my mother language.
Before flashing CM11 you were on stock 4.0.4 / 4.1.1 / 4.1.2 or 4.3 ?

I had MIUI before I flashed CM11 with the CM installer.
And before I flashed anything, the Version was one before 4.3, I think it was 4.2.
But I updated the firmware over the android updater, maybe it was at the beginning where I bought it 4.0 or 4.1.
Is this important?

Yes if you have moved/flashed from any version below 4.0 4.1 4.2 etc to 4.3 then your efs has changed from v1 to v2 read this >> http://forum.xda-developers.com/galaxy-s3/general/ref-imei-efs-stuff-i9300-including-t2393289 << tip try flashing the efs v2 aroma zip file in the thread with a custom recovery
[Q] "No Servicce" and "Baseband Unknown" after flashing CM 11 on i9300
BACKGROUND:
The plan was to flash Resurrection Remix for S3 and go from stock JB to Lollipop on my GT i9300. However, incessant bootlooping made me change my mind and I decided to settle for CM11. CM11 works like a charm except that I have "No Service" problem and "Baseband Unknown". I did do a Nandroid backup prior to all this.
WHAT HAVE I DONE SO FAR?
I was reading up on this and similar threads show that I must flash a modem. There was a list of modems on another XDA thread but it stated that these will work with stock JB only so no luck there.
How do I get the phone to recept the signal again?
MISC:
ROM: cm-11-20150323-NIGHTLY-i9300
Recovery : twrp-2.8.6.0-i9300

I´ve had the exact same issue. After not having signal with Blekota Note 4 Lite V4, tried installing CM 11 and now I have no baseband. No solution yet.
Flash full stock firmware for your country then factory reset. If still the same then restore your efs backup.

Solved it. However, WhatsApp no longer works. It doesn't send me an SMS verification after having switched back to stock from CM 11. Thoughts?
Hello!
Phone Gt-i9300
So i was happily using omnirom for 1 year until my motherboard died last week
so i ordered a new board. i installed it, it was on 4.1.2 unlocked, and i decided to update it without making a efs backup! so dumb!
So i installed a 4.3 Stock ROM, no signal so i had to install
-Patched XXUFMJ9 kernel
- Patched BUUGMJ3 modem
So i can use my phone with no problems in STOCK....
BUT. I hate STOCK..
I have tried to flash omniroom 4.4.4, but it says unknown baseband, uknown imei.. i tried installing omniroom and then installed again the patched modem buugmj3 and ofcourse nothing happened...
So.. my question is.. Am I forced to stick with this TouchWiz Rom? or is there any way for me to do something to get omniroom detecting my signal?
Oh something i was forgeting.. before i updated to stock 4.3... i installed first omniroom.. but i decided to update to stock 4.3 because i was getting signal but it could take 1 HOUR for the phone to get the signal.. and from there signal would lose at any moment.
anyone? i read the FAQ and did this
Q9: I'm sure I've correctly flashed an SGSIII ROM with the right CSC for my network but why can I still not make calls?
If your phone was running an Android version less than v4.3 before you flashed a new ROM then you may need to install a patched modem and, if you upgraded to a newer stock ROM, a patched kernel too such as the zuluman modem FW/kernel. You will usually not need to install a patched kernel if you install CyanogenMod or a CM-based ROM. A number of kernels and modem firmwares patched for Android 4.3+ are available here.
