[Q] Root Samsung Galaxy Sll - Tombile

Hello everyone,
I recently got an upgrade though T-Mobile (in UK) for a Samsung Galaxy S2. Its simply awesome, but I'm a newbie to the Android OS. Hence I have very less knowledge as to what is happening with the android OS rooting, updating etc.
So on to the main topic, I got my phone (model GT-I9100) on 2.3.5 and the base band is I9100BOKJ1.
I would like to remove the T-Mobile branding and the other software which there installed have it.
So could someone please guide me though how I could root and update my firmware to Standard samsung with out the carriers crap installed and still use the phone with my carrier?
My phone is unlocked by default as another sim card works from another carrier.
Could someone walk me through step by step as to how i could root and update my firmware to standard and unlock the device Any help is much appreciated.
I have attached a screen shots of my x#1234#
Thanks.

[Q] Stock ROM forSGS III of Bouygues Telecom France

Need Stock ROM forSGS III of Bouygues Telecom France
Few months ago I bought an SGS III GT-i9300 with CSC of CHU running stock ICS 4.0.4 ROM (bouygues telecom). The phone was originally bought in France, and later on when I came back to my home country ie Pakistan, I got it unlocked so it could work on local carriers. The long of the short of the story is, last sunday I decided to update my SGS III to the leaked polish JB ROM I9300XXDLIB_I9300OXFDLI1_I9300XXDLIB_XEO. This resulted in loss of connectivity with my GSM network. Sadly, I made the cardinal mistake of not backing up the original ROM, in case I needed to go back. So now I am kind of stuck with a phone which at best is just like a small tablet ....
Can anyone please help me locate Stock ICS 4.0.4 ROM for the above CSC region? As so far I haven't been able to do that despite hours and hours of trying.
Also, can I install Stock ICS ROM for CSC PAK/WDC on it? If so, how can it be unlocked & made to work with it?
I hope that someone can help me in resolving this issue. Thank you.

Thanks alot JJE. Didn't knew about this checkfus tool, but it sure is one very handy util. I will let you know of the progress asap.
Regards.
Okay, I used CheckFus to locate the ROM, downloaded it, wiped/reset S3 before going ahead and installing the ROM. But unfortunately it didn't help. By the way CheckFus in Product Code field says 'Not Active'.
I was wondering whether I should get unlock code, will it help solve the issue?
In continuation of my previous post, here is an image from Galaxy S3 Sim Unlock.

That "Not Active" against the product code is probably the cause. Any help will be hugely appreciated. regards

[Q] GT i9100 from Claro to ???

Hi,
I am not brand new and have usually been able to find what I need on my own. This time it's not so easy.
I bought a GT i9100 from EBAY. It had a broken lcd. I replaced it, turned it on and noticed it had CLARO version of ANDROID. So I flashed with Odin to an official GT i9100 ROM from SAMMOBILE that I have used on many GT i9100's. Then I connected to KEIS(KIES) and was notified of a firmware update which put me on 4.1.2 baseband I9100xxms2. BUT it is sim locked??? I thought these were International versions with no locking?? I know I could probably use GALAXSIMUNLOCK which I used once before but would rather try to complete the FLASH to International version if my understanding of that is correct.
Does anyone know of a ROM/KERNEL that would achieve this?
Thanks, Steve
Claro's firmware are all branded and it's devices are all network locked to any carrier but claro (obviously).
Hence you need to root it and unlock it, you can do this with any firmware, stock or custom.
And stay away from kies, use odin.

[Q] does optus version of s3 supports international firmware?

I have samsung s3 i9300 Australian optus version... it has stock optus firmware with boaltwares, apps I never use and an annoying logo at startup... was wondering that does it support international normal firmware with normal logo and no optus apps....if yes will it give me any kind of problems and will it be still unlocked?
if all the answers are yes plz give me the link of step by step guides...
thanks in advance....

SIM card wont register on phone.

Hey all..
I had a weird thing happen to me today, my s3 GT-i9300 wont register the sim at all it all started when I flashed 4.3 from 4.0 today I've tried everything possible to get the sim to register. In all honesty, I've become discouraged and would be happy to just get back to stock rom... at least the network was working. lol
Originally I bought this s3 in HONG KONG, the baseband version that I flashed 4.3 is from Kazakhstan.. So I went over to http://samsung-updates.com/device/?id=GT-I9300 and found that TGY (Hong Kong) has 3 firmwares: I9300ZSUBNB1- 4.3- 26.02.2014 and I9300ZSEMK3- 4.1.2- 06.11.2013 and I9300ZSEMC1- 4.1.2- 11.03.2013
Question: Which one do I use? and what would be the steps in fixing this problem?
Heres my info:
IMEIs match on BOTH in status of phone and on the back of the phone
Im currently on 4.3 Android Version
Current Baseband version: I9300xxugna8 [Kazakhstan]
Cell phone carrier: Mobilicity (Which is owned by Rogers)
Thanks for all the patience and help in advance.
Cheers.
Nevermind gents, found the solution. ANDDDDDDD the best part is.. I can stick with the 4.3... [sarcastic YAY]
Solution thanks to the folks at AndroidVeterans
Maybe the ROM you used is not Stable 100% that's why u faced that problem. So the solution is to back to your stock ROM with the official baseband that it was installed before you upgrade. in my opinion if you flashed a stock ROM with the wrong baseband can make your device unsupportable to the network (even you flashed many ROMs the problem will still exists)

Don't panic bro ,international S3 had this problem on updating manually , not for custom roms only for stock 4.3
The only solution is z3x box , it can be only done using that box :good:
You have to only repair network from it
