Hi, I recently got an international Galaxy S3 - my first Android phone. It's an unlocked Spain model (not tied to any carrier), and I upgraded it from 4.0.4 to 4.1.1 as soon as I took it out of the box. I've been rooted through Chainfire's ExynosAbuse since it was released. I've never used Kies; the only update I've had was done OTA.
I wasn't planning on messing around with ROMs for quite a while, but I considered installing a 4.1.2 ROM after seeing the Premium Suite announcement. I figured I'd wait however long it took for Samsung to release 4.1.2 to Spanish phones... but reading that the XXELLA upgrade fixes the sudden death issue - something which I've been quite worried about - I kind of want to just install it, assuming there's no adverse effects. And if the eMMC bug causes damage to the chip over time, I would like to install the hotfix as quickly as possible... (I do have the affected chip and FW rev)
I have been reading up quite a bit in the GT-I9300 sections here, and I think I've got an okay picture of how stuff goes, but I do want to make sure before I do anything with my expensive phone! There is an overwhelming amount of information and it's hard to keep track of everything. Anyway, here's what I was wondering...
- What's the best and safest way to flash the 4.1.2 ROM? It seems like I can use Odin, Mobile Odin, Heimdall or a recovery... but I assume I would need to flash the latter through one of the other three? I use Linux, so I would prefer to use Heimdall over Odin (if it's not more risky). Is a recovery required for custom ROMs, or is it just for convenience? Is it safer than the other methods?
I should also mention that if I used Mobile Odin, I would have to use the lite version as paid Play apps aren't available where I live and I don't have a credit/debit card anyhow.
- Would doing this get me the same result as installing it through Kies or OTA if it was officially released for Spain? (eg. the properly updated kernel/bootloader/modem/whatever else...) Including the famous eMMC fix...
- Are there any adverse effects to installing a ROM belonging to a different country? I think I'd probably end up going for the UK version.
- Would I keep my installed apps, settings, etc like I did with the 4.1.1 OTA update?
- I may end up installing a custom kernel later on (possibly Perseus or something of the like); is there anything I should take into account for this, like what method I use to flash it? And would I lose my data through doing this?
I hope I haven't asked anything too dumb, lol. Thanks very much!

Use hEIMDALL
. Is a recovery required for custom ROMs,
Yes
Is it safer than the other methods?
No

Possible need to flash modem or CSC for your region / network
- I may end up installing a custom kernel later on (possibly Perseus or something of the like); is there anything I should take into account for this, like what method I use to flash it?
Follow the kernels instructions .

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 ***
HALL OF FAME
People who contributed most to this thread and helped countless number of people with their problems/questions. In no particular order.
Currently none. Hopefully soon.
Big thanks to Undercover and Xanthrax for this thread model

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.

Hi guys,
I'll receive my S6 Edge in about 3 weeks. Quick question please:
I'm hesitating to root it however, I'll probably want to install a new official ROM (phone i'll receive is from Vodafone but I want a generic Lollipop one).
Is it possible to install a generic Android 5 ROM via Odin via a PC and not root the phone at all?
thnx

Holy **** man... You talk the talk but you defenetly don't walk the walk.
What I'm trying to say is that its way to early to even talk about these things.
First of, we got root but NO custom roms. I don't even know if we have a custom recovery out yet... My guess is no.
And custom Original Samsung ROMs we will have in due time (like Omegaroms and alike)
But custom CM12/AOSP will not happen any where near this half year if ever as Exynos is closed source and most of it has to be hack built. So forget stability too...
Just understand this first before even considering buying the s6 or s6 edge.
I don't think you understood my question here...
I NEVER talked about a custom ROM!! I want to ditch the vodafone ROM and install a generic BAU ROM instead which WILL be available very soon on samfirmware website. And even if it's not available in the next few weeks, it doesn't matter, my question is generic and could fit ANY phones really.
My question is: is it possible to install a BAU ROM without rooting the phone?
Simple, not sure how to explain it further
Ah I get you now. Sorry.
What you are talking about is "unbranding". Yeah that should be easy.
You don't need to be rooted to be able to flash a stock unbranded ROM.
YES! You actually found the word I was looking for and should have used: unbranding! haha SORRY
Yeah, I too thought that I didn't need ROOT to change ROMs if I do it via ODIN and a PC, but I wasn't sure
thnx again!

Actually it is very dangerous (from what I Have been told) to flash any stock firmware via ODIN on any phone except the model it was intended for - that could and probably would brick your phone - IF it was able to flash at all - which is highly unlikely.
I don't know everything - and many here know a lot more than I do - but from what I have read and been told by others smarter than ME _ NEVER try to flash a rom via odin on your phone unless it was specifically made for your model.
Good luck - I hope you find what you what you are looking for.

hi there ppl,
im new to this device, just got it few days ago, but my model is the 4g/LTE/ G7105. and it comes with JB 4.3
so i've search google, you tube, xda, and few more forums and found nothing on how to root my device. i know that there is a way to flash stock KK 4.4.2 firmware of other region from sammobile website.
i really dont care about the warrenty issue, mostly i wish to debloat the stock rom and flash custom recovery.
but i have few question if someone can help
1. i rather stay with JB with this device, so if anyone have this device G7105 rooting methood and did manage to root it pls share .
2.if i do decide to flash stock KK what happens with knoks, will it have effect on device (except the ticker which i dont mind) if i want to flash stock JB back ?
3. if i flash stock KK of region like france germany or greece, and my region is israel, will it have effect on my 4g/LTE connection and other network and gps problem?
4. last question, can i change modem if the above question mean i do have problems ?
i have galaxy s3 also but i was a lot easier to handle rooting, and since its a bit of different ways i dont like to mess hardbrick my device already.
thanks for all helpers
The only S5 Kitkat ROMs I've found either haven't been updated in over a year, or many users are reporting severe bugs like no camera support, or severe battery drain issues.
I'm just trying to get an app called Winulator running so I can play Starcraft: Broodwar on android, but it isn't working and one user said that is because Lolipop broke it (I'm on 5.1.1 atm). The app is no longer supported so I don't think it will ever run properly on 5.x. If anyone knows of a way to emulate 4.x for just 1 app maybe that would be the best shortcut for me overall here.
Barring that, could someone please recommend a guide to installing a lightweight, power-user-oriented ROM that is 4.x or older and has excellent battery life? I was going to try the official 4.4.4 VanirAOSP release but there are too many reports of poor battery performance in the last 2 pages of that thread for my liking.
I think the first thing I need to do is unlock the bootloader, and I've yet to find a definite answer on the best method of doing this from FOL1 (12/15). It seems I will need Odin on my PC and I have it. I've also started backing up all the data from my phone by manually copying/pasting to my PC.
I guess once everything is finally backed up (it's taking FOREVER, explorer literally been calculating time to copy for 10 minutes now just on the phone/android folder), then I will try and flash the official 4.4.2 VanirAOSP ROM since that one doesn't have any reports of battery issues and possibly only the camera and a few things won't work.
BTW, is there a step specially to unlock the FOL1 bootloader that I am missing, or can I just flash that ROM with Odin straight up? I found a comment stating NOT to flash 5.1.1 with Odin or I'd be stuck on Lollipop until some new bootloader-unlock method comes out. The 5.1.1 I'm running wasn't flashed with odin it was sent OTA and I've never rooted or had custom rom/bootloader, so I should be good on that I guess?
I am actually about to dive into this, if no one has any suggestions for me: http://forum.xda-developers.com/showthread.php?t=2752995 (don't bother, too many missing major features)
edit: I used this guide and it was quick and painless, highly recommend! http://forum.xda-developers.com/tmo...l/root-how-to-root-sm-g900t-firmware-t3358190
Unfortunately the "sick n twi5ted" rom that I chose to install (only because the 600+ Infinity ROM thread has broken DL links) is a buggy PoS on the g900t so I'm still looking for a decent rom.
