By searching the forum

This is what i done. Flash stok 4.0.4. Siyaa Root it, go to unlock s2 in market. Make sure to back up ur efs folder. Then flash a custom jb i did militant its the BEST stock like rom, and it shouldnt remove the network unlock.

That is absolutely ridiculous.
Look children, this is what happens when you cant be bothered to search, you go and pay some idiot to do what you should have done in first place, ie search, read, learn and do.
If you had search you would have found many topics that recommend various unlocking apps from play store or on xda and unlocked you device in seconds.

Thread Closed:
Questions like this have been asked before and can be answered by doing a little research (searching).
If you plan to advance in your knowledge of android you are going to have to learn and not just expect help on already answered questions.

[Q] Rooting s3 i9300

Hello guys
I have a S3 i9300 uk locked to three network and it has xxdlj1 build and NEDLI1 base. I need to root it but keep the branded 3 firmware and unlock it.
Iv seen the links around and most of them tell you to install custom rom first and then root with a file.
Can I just root it and not install new firmware ( its on 4.1.1). im new to this stuff and iv read a lot on the forum with a lot of help around.
Thanx for the help appreciate it.

Iv rooted my s3 using cf root 6.4 ( not auto). Its on 4.1.1. now i know that 4.1.2 is out i really like the multi tasking feature and really want to update.
The only thing is that i want to unroot know but im not sure where to start. iv read up on this site to unroot s3 i9300 (galaxys3root) and i want to go back to stock firmware. I want everything gone also the root(supersu, cwm manager also the aptoide and stuff like that. Basically so the warranty is intact again.
the method shown is it good and is it compatible with the way i have rooted? Galaxys3root
since my phone is branded to 3 network in uk can i install unbranded firmware so the 3 start up sign goes away or shall i stick to same firmware.
Appreciate the help the people give on here. Thanx alot

Need help with rooting

Hi guys,
I have a samsung galaxy s2 and i need to root this phone. It is running ics 4.0.4. I read in the threads that rooting 4.0.4 will cause trouble.
Is there any other way to root other than downgrading to 4.0.3
Any help will be appreciated.
Thanks in advance guys

Flash Odin version of Siyah kernel (search for how to/which kernel you need to use). Done. Rooted phone + CWM, you can flash whatever you like/wipe till your bum gets red.

What thread/reply have you been reading because their talking crap or you have mis-read/misunderstood.
To root your device, install cwm all you need to do is flash Siyah kernel via ODIN or one of other various ways. This has already been discussed over and over again so we dont need yet another topic just to repeat everything again.
#1 rule by XDA is to search and read topics before creating them.
This has already been discussed over and over again

Need help urgently!!!!! :'( PHONE NOT UNLOCKING

HEY there guys... I need help regarding a problem i am facing.. And it is about the rom that i just flashed on my gt-i9100
Now the prob is i was using stock ics rom with siyah kernel. And i dont know why, but i decided to flash stock jb rom which
has just leaked for s2.now as i flashed my phone is kind of factory locked, i tried to change the csc which was described in
the rom description but nothing worked .. I tried to find the unlock key via chainfire's app but it also didnt worked... Now for the time being
i have reverted back to stock ics but the prob is when i start my phone it asks for an unlock key and i dont have it so my phone
is working as a f*****g ipod right now.... i.e no working sim..
Plz tell me what to do now & if there is a way to install jb stock rom without factory locking the phone
Thanx alot.....

Look dude, the simple matter of the fact is that you're not special. Other people have had 100% exactly same "problem" as you and have solved easily by reading the topics that have already been created about this matter.
We have various topics on unlocking sim after flashing JB so go read and learn.
creating duplicate topics and labeling it as "URGENT!!!!" doesn't help you it just irritates people into not wanting to reply or help you.

If i understand right what are u asking for is an UNLOCK code for the phone because it is not booting up at all and u can't even get to sim unlocking screen where u have to input ur PIN ? Is that correct?
If yes, i've had same problem on my old GalaxyS, im not sure if it will work on S2 but here is what i did.
1. I've typed in random letters, numbers few times
2 Phone said if i'll put in another wrong code it will format my SD card.
3 I did that anyway.
4. Phone was unlocked and SD cart NOT formatted.
If u can go to recovery mode u can try to mount usb storage and make a backup of ur SD card.
I hope it helps.

No... Its not the case. I come across that screen but i dont have any key to put in so i just dismiss the msj... And the phone's working but the sim is not registered... I was thinking if it is to do anything with the country i am living in.??? Any ideas?
I suppose ur not asked about PIN code, so there is no sim card inserted or phone is not recognizing its presence. Maybe its silly but pull it out and push back in. If there is no contact problem and u have tried various roms and kernels then i would start suspecting hardware issue.
Post a screen shot.
And it better not be a SIM PIN code.

No its not. The phone is asking for a factory unlock code.... just right now I am on jb rom xwls8 militantRom using the app (galaxy s unlock) but all in vain... I searched the forum and came across that if revert back to ics, backup my efs folder and then install militantRom then there wont be any problem but nothing changed for me here

GalaxySim Unlock is one app, Galaxy S unlock is another app.
You need busybox, got busybox installed?
Ask yourself, do you really wanna unlock your device?
Start paying attention.

well, if you asked this in the i9300 forum, you would indeed get the correct help, but this is the S1 forum, so most will not be able to help.
anyway go here . I will ask MOD to move you to S3 forum

Sorry, I thought I was in the I9300!!!
Stock rom from sammobile includes bootloader, but I seriously doubt you've actually broken the bootloader. If you have then you'll need more than just an odin flash to fix it.

There is no more link for 4.0.4 stock rom for gs3 anymore. I dun think 4.1.1 even has a download link anymore. Unless u had a nandroid back up, it is impossible to go back tat far.
