Galaxy S3 GT-I9300, back to stock - Baseband version? - Galaxy S III Q&A, Help & Troubleshooting

Hi,
I'm sorry if this has been asked before but I ran a custom rom for a while on my Galaxy S3 GT-I9300 and now I want to restore it back to stock. According to my phone's menu, the baseband version is I9300XXUGNB1 but that version is not te be found on Sammobile firmwares. Can I safely install another rom with another baseband version? For example I9300XXUGNJ? (Netherlands). Or will I risk bricking my phone? To my knowledge the S3 I own isn't uncommon or anything. It's just a carrier- and simlock free phone which I bought at a major electronics retailer at the time.
Thanks in advance.

Hello and thank you for using Q/A,
you can flash all ROMs. But please keep in mind to backup EFS and then flash.
Kind regards
Trafalgar Square

so lets just say.. god forbid, the efs partition got facked at some point.. i may as well consider the phone bricked?

no you should be able to flash stock with odin and start all over (no root) if you didn't backup efs
not sure how its done though

Hi,
yes you can update to lite'ning rom.
But it's better to flash an original samsung rom first if you are running a branded one.
The roms are available for download (check dev threads)
You can flash back your stock rom by the same way as flashing lite'ning rom.
cheers!

For the same rom, almost same question:
I am on unbranded CSC: XENKE1 (Netherlands); (PDA:XWKE2; Phone: XXKDJ)
Can I flash latest Litening rom, based on KF1, to my phone? Will this give me a UK-CSC? Or will I keep my Dutch localization?
Sorry to thread jack this, but i didn't see the need to create a new one, i bought an unbranded sgs 2 and i have
PDA: XWKE2
PHONE: XXKDJ
CSC: OXXKE2
Seeing as the lite'ning rom is based on XWKE7 should i flash this firmware first? is this thread reliable, do these roms restore warranty ?
I am also interested i hearing about backups for warranty purposes since this is my first flash.
NVM: i just realized those roms are rooted, where can i find stock ones, does anyone have a link?

Just flashed from an unbranded i9100, Dutch edition (XEN) To Litening rom 1.4, without a problem - All apps remain, all localized settings remain; Done in a jiffy!
(btw: it was my first android-flash... w0000t! Coming from iPhone 3g, jailbroken)
(PDA: XWKE2 / PHONE: XXKDJ / CSC: XENKE2 - so almost like yours, only different localization)
Regarding your 'no-root'-question, and warranty:
-When u flash a custom rom, a counter goes up, assuring Samsung can check if u flashed custom stuff to your phone
-It does not matter whether you flash a rooted or unrooted CUSTOM rom: the counter is to check for custom flashes, not for root versus no-root
-It is uncertain but highly likely that Samsung will check the custom-rom-counter to deny warranty
-BUT: in-case-of-emergency you can reset the counter using a special USB-jig (cheap)
-BUT: there might be a 2nd counter (hypothesized, not proven as far as I know), counting the number of counter-resets using the jig (still following me?)
-The bright side: in the Netherlands/Europe the company you buy your phone from is responsible for the warranty, not Samsung; Customer rights are pretty tightly regulated by European law, protecting customers from companies denying warranty... As long as the damage is (reasonably) not due to the flashing, you're still good for warranty over here (in THEORY - try to explain this though to some dumbass uptight salesman)
Thanks for enlightening me, but what if i don't like a feature in the rom and i want to flash back to stock, i can't find any definitive stock roms thread, other than the one i have mentioned in the post, which should be ok, since it's stock asides from the root, i'm gonna try lite'ning, have any favorite roms yourself?
I've never actually had a smartphone, i come from an iPod touch which is close enough , always bothered me that i couldnt do anything with it, i consider myself an explorer
EDIT: Just flashed lite'ning, got a little bit scared cause it took a bit to boot, but everything's fine now
Noob questions
another hijacker! but relevant i think
Ok so iv just moved from a iphone to the samsung s2 and im loving it i have had it for about a week now and a iphone just feels wrong! lol im new to flashing android phones etc but have a lot of experience in jail-breaking and from what i have read and see it seems a lot easier to root and flash android phones! bonus! i have a orange samsung galaxy s2 ;
PDA : I9100KVKE2
PHONE : I9100BVKE2
CSC : I9100ORAKE2
Build info wed 11may
i have read all the root de-branding stuff . custom roms etc and i understand it to a degree but i just want to know where do i start? should i de-brand first using the page on the developers area then root then flash a custom rom? i wanna lose all this orange crap. plus is the orange firmware/rom available to go back to if i ever need to take it back? i would appreciate someones guidance on where to start. i quite fancy the lightening rom.
Fortunately from what I've read so far, lite'ning won't "wipe" your data aka contacts, applications, etc. So all of your applications including orange applications should stay, about going back i can't help you, though i'm interested in hearing from someone who knows more about this.
You should know that just by updating to a version outside of your carrier's allow zone, you automatically lose warranty (custom or not, root or not).
Offtopic: Glad i bought mine unbranded, from i've read around the webz before making my decision, it's well worth the money not having to deal with carriers.

but if you can restore it to the orange original rom stock and use the jig to restore the counters. if there isnt a hidden counter they wouldnt know,
Thanks all for the response. No issues in hijacking, i was going to ask those questions anyways
I have a rom that is specific for India (localization, etc), so when I into the Android Market I can see the price of the apps in the local currency. I havent bought one right now so dont know how the payments work.
Secondly, the warranty - thats a problem. If I flash it and have to take it back to Samsung for any reason I am stuck, especially when you know you might have a hidden counter.
So as much as I would like to go with Litenin ROM, losing warranty for me right now (since the phone is just couple of days old) doesn't make sense. I will rather wait for some more time till all info about GS2 is available before taking the risk.

[Q] how to recovery lost imei no Samsung Galaxy s2 gt-i9100?

i have Samsung Galaxy s2 gt-i9100(rooted) and suddenly my network signal was missing. and i dialed *#06# and display no imei and unknown baseband . so how to solve that problem?
gt-i9100
android version - 2.3.4
baseband - unknown
kernal version - 2.6.35.7-i9100xxkh3-cl479037 [email protected] #2
No EFS backup ? Try flashing some stock roms. If that doesn't work, service centre or local mobile repair shop; they have equipment to write the IMEI back to the device.
Yes sir i have i have tried to restore but it didnt work
neddinary
Sir give links to flash rom
plz
Samfirmware. No, I'm not going to give you a direct link; did your last slave die of overwork per chance ?
same problem
what firmwere should i download if it dosnt show up any baseband version????
Did anyone gotta solution?? :crying:
Try all the firmwares for your country/carrier (not 4.0.4 though, just in case you flash & forget then do a factory reset. If you've flashed a couple of those & your IMEI hasn't returned, it's fairly safe to say it isn't coming back; take it to a local mobile repair shop, many have the equipment to re-write the IMEI to the device fairly cheaply.
Did you manage to sort this? I was asked to look at a friends S2 which was showing no IMEI number, and I managed to sort it....

Spill the beans then; what did you do to fix it ?

Ah.... this fone was completely stock, still running Gingerbread 2. whatever!!
So.... all using Odin....
I updated-no joy
I rooted-no joy
I flashed newer custom ROM-no joy
Then, I tried flashing Stock 4.1.2, and away it went!!
IMEI number replaced, fone now working, friend well impressed!!
The files are I9100XWLSW_I9100XXMS2_I9100XEULS5_HOME.tar.md5
I'm not sure how to post a link (perhaps someone could show), I got them from YouTube, but have them if anybody needs them.
But if you Google for that, and you're on UK S2 I9100, you should be fine!!
Hope this helps some people, please bear in mind the usual : "I cannot be held responsible for any damage caused...."

[q] imei lost after unroot

Hello Guys. I went into a bit trouble here...
I have Samsung S3 for more than 1 year, and I already flashing it with custom ROM without proper backup (foolish yeah i know)...
And now, I want to return to my official stock rom (unroot). Since i am from Indonesia, I found that the latest firmware my country has from S3 is 4.1.2 (from samsung-updates and sammobile websites) like this :
GT-I9300 Galaxy S III
PDA: I9300XXEMF6
CSC: I9300OLBEMF3
MODEM: I9300DXEMB1
Added: 2013-07-23
I reset the binary counter with triangle away and unroot it with mobile odin, but the problem is my imei was like "0049...../1" and I cannot make any calls or sms (not registered from network).
After reading a bunch of threads, i found the solution was to root it back again and install modem XXEMG4...
Is there anything I could do to have a working unroot phone? like using official stock rom from other country perhaps?
cheers
Yes it is the Modem problem. And for heaven's sake as soon as you root make a backup and backup your efs partition as well before you get into a bigger mess. Flash a stock rom that has the modem MG4 or flash a 4.3 rom of any country it hardly matters.
If i unroot it with a 4.3 rom from any country, then can i update through option "software update" or should i flash it again if there is any update in the future?
Thanks for the explanation!

no i dont think...but you can try by KIES..that may be possible..but some users have reported that kies also doesnt work for them..but you always have ODIN to flash firmware of other country or any your country whenevr it comes..
:good:
So i still have to root it?
Root doesn't matter, you cannot use the firmware of modem for your country as it is efs v1 and you didn't take a backup before you changed to v2.
There is no way back, you'll just have to wait for 4.3 to be released in your country if you want stock and unmodified status again.

Stock rom

Goodmorning everybody,
I'm afraid i need some help with this (http://forum.xda-developers.com/galaxy-s3/general/fix-s3-to-factory-unroot-stock-recovery-t2323847) guide i'm trying to follow.
Except nobody is answering on my reply so that's the reason why i'm opening a new thread. forgive me if this is not the right section.
I'm pretty noob in all this so i will try to explain my situation as good as possible so that you can help me in the best ways you can and want to do.
The beginning
about a half year ago i thaught it was cool to have a custom rom on my galaxy s3 GT-I9300.
I did this with the help of a friend.
I first adjusted the recovery to clockwork and installed cyanogenmod.
The exact details of my phone at this moment are:
modelnumber GT-I9300
Cyanogenmod-version
11-20140708-Snapshot-M8-I9300
Android version 4.4.4
Smalbandversion I9300XXUGNA8
Kernel version 3.0.64-CM-g5e96596
CPU ARMv7 processor rev 0 (v7I)
Build number CM_i9300-userdebug 4.4.4 KTU84Pd9438c2c60 test-keys
I've got a new phone and want to give this phone to my sister or sell it.
I don't need it back to stock for warranty.
I just want to hand over a clean and simple phone.
The problems i'm running in to are...
I did download and install triangle and i tried to reset binary counter.
The counter stays at 1 and the kernel stays at custom. the last visable option says official after triangle.
I also did flash the original recovery with Odin, (jaj this worked) because i can start up in the original recovery mode and not in CWM.
Before i do a full wipe i want to know what the problem will be when i install stock firmware with a binary counter on 1.
And this leads me to my second more important problem.
I can't find which stock firmware i need.
When i try to dial the codes to look up which one you need. I get a error message that it isn't possible to view this information.
I personally think i need: Galaxy S 3 (International) GT-I9300 PRO I9300XXALF5 Android 4.0.4 07.06.2012 686526 Unlock
there are 2 mirrors on of which is not workiong and the other downloads at 50kb/s and stops at around 90 mb in of the 700 total file size.
Can anyone tell me which stock firmware i need and where to download it? i've searched google (ofcourse) but can't find any.
I live in belgium, this phone was bought in Belgium but i have a dutch simcard working in it from the provider youfone.
This is a sim-only provider and they use the network form a bigger company called KPN.
I really hope someone can help me with this because i'm too afraid to do something wrong and brick my phone.
Sorry for being a noob don't bash please!
Thanks in advance for all your replies!
Grtz
Just flash the latest stock firmware for your country using Odin then factory reset in recovery before booting. Download from sammobile.com
You are confusing yourself with all the other things you are trying.
