Hello from me! My first post!!!
Well I was wandering how can I flash the sammobile dowloaded firmware with Odin3. I mean full flash so I can change the phone and CSC not only the pda. Because what I get from sammoblie is a one file bundle *.tar.md5 .
- Just in case, I recently bought from ebay a GT-9100 locked with T-Mobile and stocked with Gingerbread. I am not a customer of T-Mobile so I unlocked it and upgraded it to latest firmware 4.0.4
- The problem is the signal strength is very poor (but not always - sometimes, for about 10 minutes I might get full H+ and after that no signal (wtf)).
I am not sure whether it is a software or hardware fault and wanted to downgrade back to Gingerbread.
Any help is apreciated.

Any idea on the second part of my problem?
Plus, when I flashed Gingerbread I got stuck in set up wizard due to errors. And I was not able to factory reset the phone.

[Q] Firmware update via odin for sim locked SGS2?

Is any problem to update my SGS2 firmware via odin (with latest 2.3.4) if its sim locked? Should I use my old csc (KG2) from my provider or I can use the multi csc from KG5? Thanks
It should not be a problem updating to xxkg5 as all the provider information is on the sim card, only time you would need csc if a different language is used.
Sent from my GT-I9100 using XD
Be careful because if you use odin you are flashing your phone and i thought that sim-locked phones couldnt be flashed??!!!
You Can flash it
I just flashed my SGS II yesterday to 2.3.4 and its sim locked to TMobile UK,
Its debanded it however it now reports it cant be updated in kies, see attached image.
that is normal as kies only supports samsung branded firmwares. Odin works better.
you can still use the other features of kies except updating.

I debranded my T-Mobile UK SGSII (KE3) to Stock KE7.
Connect my phone to my PC with the Samsung software. It said that there was a software update and downloaded a stock KF3. I had to reroot the phone afterwards.
Is the reason perhaps that i have installed kg5?,
TBO i am overwhelmed by the amount of diferent firmwares and other info on this site.
I can report that it appears to be working fine though on my phone.
I changed it to kg5 using odin and downloaded it from samfirmware.com

That is exactly the reason. The official stock update is to KF3 and you are way ahead of that.

Unlocked Ace, want Generic firmware

I have an Unlocked Samsung Ace, which was locked to Optus Australia earlier.
pda s5830xwks9
phone s5830xwks2
csc s5830oppks5
network lock off
network subset lock off
sp lock off
cp lock off
I just don't Optus app everywhere and running in background. Can I use a Generic Firmware ?
If yes can someone guide me or just provide links ?
I even tried to Root it with <upd_1 & AceGingerRoot>, and I can see Superuser icon, but Titanium Back up and BusyBox says my phone is not rooted.
get stock roms from sampro.pl or sammobile and flash it using odin

My ace is optus lock too and cant get root access

Which ROM? Do I have to look for a specific ROM for my phone( according to PDA or CSC of my phone) or any one that is Gingerbread 2.3.4 or 2.3.5
get ddkq6 that is unbranded firmware and stable one [2.3.4]
Dear WiseMan Amit,
I am sorry to ask again, did u see read these stats *(pda s5830xwks9_phone s5830xwks2_csc s5830oppks5) of my phone before suggesting? I dont want a brick.
And after flashing that Rom, Will my phone update with Kies itself?
BTW what does this PDA PHONE and CSC mean? Shouldn't I choose a Rom according to them?
I am sorry again for bothering you. But .

i saw your version
flashing will not brick phone if you flash 5830 roms with proper instruction which you can get in some sticky
offcourse your phone will be updated through kies but you will have to wait for update for that specific region [in this case india if ddkq6]
all GB roms on sammobile are flashable for you...
PDA CSC stuffs give you info about region , specific identifier for update etc stuff
i was also very much concerned when first flash phone with odin... read instuctions carefully and flash device specific roms only
you might not be able to get updates through kies as samsung delays updates between regions.. so most of guys flash through odin itself
Thanx really a lot mate.
but I could only find DDKQ5. not 6
And as I am not able to root my phone, how do I back up my current Rom?
I couldnt resist and flashed S5830XWKS9_S5830XWKS2_S5830VGFKS1_HOME.tar.md5
Everything working but I have got Virgin Mobile shortcuts and Jeux game. Cant uninstall it.

It's available if you SEARCH in this forum
Herpderp Adreno + Tegra.
I was tempted to flash Russian 2.3.6 and I did it successfully. Cleared cache and factory reset and now even Kies accepts it and will update when available.
It is far better. I have lots of Ram available now.

Hi guys
Think it's my first post here so please be gentle :silly:
I dont know what firmware to upgrade to (or if i have the latest firmware etc.), i cant dial *#1234# code as it will return a: Connection Problem or Invalid MMI Code. *#06# is working fine though. So i do not know what my CSC, PDA and phone is?
Only thing i can find in "about phone" is:
Device: Samsung Galaxy S III GT-I9300
Android: Android Version 4.1.1
Rom: Latest version of CM10
Baseband Version: I9300XXXLE8
Operator: Denmark - Telia

Look on www.sammobile.com/firmware for samsung firmware.Telia is not listed, also not on check fus. So i think you need this rom http://www.hotfile.com/dl/163050326/a3cfdf1/I9300XXBLFB_I9300NEEBLF1_NEE.zip.html for the Nordic countries. Install Triangle Away (here http://forum.xda-developers.com/showthread.php?t=1494114) first before flashing the rom with Odin to reset the flash counter. After you flashed the rom do a data/factory reset. Check first if the above rom i mentionedis the right one.
Was reading abit more (do not want to be stucked with a broken phone doing my vacation), found this is the I9300XXBLG6 the newest firmware and does it work for us on Telia in Denmark?

Better check on Telia`s website for the latest firmware. You might flash the rom in your post, however you may have to change the modem for better reception.

If i flash the new firmware again, do i need to root the phone again or does it "keep" the root i made earlier... Sorry for all the stupid questions i'm an old iphone fart. :silly:
I tried to search for a sammy wiki or something to become a little more clever about rooting, rom and firmware.
As i see it:
The firmware is kinda the phone bios, doesnt matter if you running a hacked version of the system or not.
The ROM is the "system" it might be stock or cyanogen etc.
You have to have a hacked firmware to be able root your phone.... Or am i totally wrong here?

If you buy Mobile Odin Pro and flash the firmware with that app you will keep root and you don`t loose no data. If you flash with Odin on your pc you will loose root and your user data will probably be deleted.
The firmware i just linked is it not possible to root using that and odin nonpro? Do i have to use an older firmware then?

Flash it with Odin and root with CF Root 6.4. You can flash that firmware although i wouldn`t do it, it is a British Telecom provider rom. I would flash the rom in the 2nd post (nordic countries) wich i recommended. For instructions see m signature.

Flashing a stock rom to an unbranded phone - OTA

EDIT: The headline is supposed to say - 'Flashing a stock rom to a BRANDED phone'
Hey guys!
I've recently acquired a Galaxy S3 yet my carrier has decided to brand the phone (Three). I've been talking to them about getting them to debrand it but they will not do it for free, and they say that once debranded I won't be able to receive OTA.
My question now is: Will I, if I do it myself, be able to flash an unbranded stock rom located on the internet using ODIN and still receive OTA updates, or is there something preventing me from doing this?
Cheers
Mikkel
I had the same issue (orange),
Go to SamMobile download the latest unbranded btu (uk) version 4.1.1 and flash with odin.
As you flashing the official stock firmware you don't need to be rooted and your counter won't change.
You will then get the ota updates from Samsung and not your carrier or you can just keep flashing the latest versions as above.

But I suppose I have to find one that comes from my country, which is Denmark. The only one I can find on sammobile appears to be a branded version from Three.

Go to the Sammobile.com site then the firmwares link and select
Type - Smartphone
OS - Android
Model - this will be your phone for example GT i9300 - Galaxy S 3
Country - and from the drop down lost select Open Europe OXA
That is non branded European version 4.1.1, it should work fine for you.
Totally up to you this is just a suggestion to get rid of the branding from 3 which is the only version listed under Denmak itself in the country list
Use CHECKFUS to download any current firmware from Samsung and flash via Odin .
jje
Thanks a bunch guys. This is great help!
Before I start flashing the rom is there anything I have to do? Do I have to backup/wipe/reset the phone or do I simply start download mode, connect it to my PC and flash the new rom using Odin?

Upgrade from Gingerbread>Jelly Bean-- HELP [SOLVED]

I have bought a brand new galaxy s 2 (GT-I9100G). It's currently on GB firmware I9100GXXLB1 from XEF france region as this was bought in france. I want to update to Jelly Bean. I have installed the latest version of kies and got everything set up. But,when downloading the firmware update, kies is giving me extremely slow download speeds(3mbps connection here) that's going to take forever to download JB. So, I want to flash it manually using odin 3.07 as other firmware hosting sites gives normal download speeds.I have downloaded odin and want to install the following firmware.
So, can I upgrade directly from GB to JB without any problems? Do I need any special .pit or procedure while upgrading or I can flash normally using it?
Please reply..

No special requirements, that's assuming you know what you're doing with Odin (fair assumption given your post count?)
Actually,this is my first time using odin. I have never used samsung devices before. I have done a lot of reading before posting this thread just to be extra clear.
If no special requirements are needed,will I have any problems upgrading directly? Also, have I chosen the correct firmware for my GT-I9100G?

As the above poster said no problem in direct jumping from gb stock to jb stock, and you don't need to touch the pit files, but sometimes(very rarely) a bootloop can occur, so in such a case just performing a factory reset from the stock recovery would fix that.

Unfortunately I'm not going to comment on whether you've chosen the correct firmware. I don't own a I9100G, so have no experience choosing a firmware for it. As long as it's definitely an I9100G (as opposed to international I9100) firmware you'll be fine

According to the filename it seems to be i9100g firmware, if it's from a trusted source then it's safe for the i9100g.
