[Q] GT-I9300 - how to unlock bootloader - Galaxy S III Q&A, Help & Troubleshooting

Hello All,
i have the GT-I9300 Europe version, rooted, JB 4.1.1
i would be happy to know how to unlock the device boot-loader since i didn't find any good or useful guide
i even heard that the Samsung have already an unlocked boot-loader - i don't think it's true.
Thank you very much.

S3 Bootloaders are unlocked cept the Verizon US Variant (which an unlock is available)

Hi,
Thanks for the answer.
if so, how can i check if my boot loader is indeed unlock?

Since early 2011 Samsung has only had unlocked bootloaders with the exception when a provider demanded it (like Verizon).
So yours is UNLOCKED.

OK thanks, but must be a way to check it, right?
i want to learn you know...

If its locked you can neither flash root nor a custom rom .
But it does not apply SGS3 I9300 has never been locked .

1) The bootloader is not locked. Your post is based on rubbish and could potentially brick an international s3. Please only post things you understand, not dangerous nonsense like this.
2) "dis" and "ur" are not proper words. The language of this forum is English and you have a responsibility to use real words. Sure, you may use less-than-perfect grammar and punctuation but at least try to spell words properly if you want to be taken seriously*
*also depends on 1).

[Q] Xperia Mini Pro Questions

Hello
Just purchased a SK17i Xperia Mini Pro Black Version that is locked to 02 (UK network). I am obvously new to all this stuff but do have a basic understanding but here are some questions:
1) I am thinking of waiting until Android 4.0 is Officially released by SE to update my phone (btw, anyone know when the update is coming). Was wondering when I update will I still be able to root my phone?
2) When I root (if I can) I want to install Set CPU to overclock my phone. However I have heard this drains batteries? Is this true and if so how can I make my phone faster?
3) I need to unlock my phone. Can this be done for free after rooting? If not, can someone link me to the cheapest place I can get this unlocked from?
Thanks in advance to anyone that answers
Hey dude,welcome to XMP family.
1)According to Xperia Blog,XMP will get the ICS update in the end of May or early June,after the first wave for arcS,neoV and ray.I don't know whether we can root it on official ICS or not,but I think to get a rooted phone is easy once you unlock the bootloader,and besides,there are so many developers here.
2)When it comes to overclocking,apparently it would cause battery drain faster.But with my experience,I hardly feel its difference on SE stock Rom.As for custom rom like FXP's,which I has used for a while,it drains about 2~3% per hour while idle(drop speed is two times than stock.)
3)Certainly you can unlock your phone for free,see this thread & tutorial.But it should be noticed that once you unlock it then you may invalidate your warranty.
Mine is on FXP CM9(ICS) and it's kind of laggy,but I can't tell it's because of the ICS rom or existed bugs.As SE said,we may not have the same experience like Gingerbread if we update to ICS.

Hello mate, thanks for the great post
I think I will leave stock ROM once updated actually, seems to be running fine atm as it is.
I think I will still update to the official ICS when it comes out as does look worth it.
Just about no. 3) I think your talking about after rooting, the process to get custom ROMs by unlocking the bootloader? I was talking about the network? lol
Unless I'm mistaken?
Thanks again

There is no way to get your phone unlocked from a network for free but WontanServer offers an unlocking for $15. You can try that out. Just type WontanServer in Google and click the 1st link. WontanServer is legit and won't steal your money
Though as a warning you might not be able to update to ICS as it also might unlock your bootloader. Just double check, as I am not 100% sure. Also it will void your warranty

Thanks alot, will take a look at that website
What do you mean by updating to ICS will unlock my bootloader? Isn't that a good thing? Don't mind about warranty, can have that sorted out but don't understand the bold line mate
Thanks
good thing in the sense? If you don't bother about warranty then you can try custom ROM ics.but the problem is some bugs are not fixed by developers they will take time.main bug is camera not working..i am using ics so just check k? Good luck
Xperian8~ click thanks if it helps...

He meant that the Wotanserver network-unlock method might unlock your bootloader (which it does). This bootloader unlock, whilst giving you access to custom ROMs etc, might not behave with official SONY updates (such as ICS) - I'd link you for proof but I'm not allowed to due to my low post count .
Also, Google 'Omnius Unlock'. They will unlock your phone for free over the next few days (Easter promotion). I'm not sure how reputable those guys are though so you'll want to check.
Thanks for that Omnius Lock thing, looks great and will check it out
So, if I unlock it I may be unable to upgrade to 4.0? That is a bit stupid to say the least? Anyone on an Xperia that was unlocked then ugraded to 4.0? Did it become locked again?

If your phone's bootloader is unlocked you can not recieve any official update through Sony as it will brick your phone but you can install a ICS ROM.

Well I'm not sure about 'stupid', you'll have to weigh it up. If you look in the development section, there's already a very useable version of ICS (look for MiniCMSanwich), which is potentially better than Sony's bloatware-infused and themed version (not to mention probably unrootable) due in a couple of months.
I think it's mainly FOTA bricks that happen (over-the air updating from Sony), and some bootloader unlocks allow for this by just patching the bootloader to make it seem unlocked (any SETool unlock will do this). So there are a number of options.
Be careful also of some bootloader methods stripping the DRM keys, these are used by Sony services like TrackID, which will cease to work (permanently) following a bootloader unlock.
Edit: There's a distinct difference between a network unlock and a bootloader unlock, the former will nearly always also execute the latter, but the latter can be done by itself (obviously only on unbranded phones). The method of getting a custom ROM is basically network unlock > bootloader unlock > root > install custom kernel > install custom ROM. Root can be done before the unlocks, I believe.
I'm new to all this too, only trying to explain because I know how much of a total pain it was to work it all out .

Network lock stays away, updating probably won't lock it again, but no one has tried and we do not have any sure information

Ah, right. Makes everything at lot clearer thanks
So if I do unlock through the Wotanserver place, my bootloader will be unlocked but I wouldn't be able to get official ICS, but a just as good if not better copy? Is the ROM fully stable as in does everything function fine? I have heard of an ICS ROM which stopped HD recording on Xperias. Does this have any such problem?

What you on about mate? Make your own thread
Also, just a quick question to add: Do I have to go to SE to get my boot loader unlocked? Or will it automatically unlock with Flashtool when I flash the Kernel?
Thanks

Thanks for that, do you have a link for me which I can use?
And just generally, can I add that this is the way to get MiniCMSanwich ROM on my XMP:
Root (zerg's software) (not needed but useful so might as well do it then)
Unlock Bootloader (from SE's website or the link which hopefully the above poster/someone else gives me)
Kernel Installation (Flashtool)
Finally, flash the ROM and Gapps using Clockwork Mod Recovery
Thanks

It is the same unlock method, just everything brought to one place by that app maker.
Rooting your phone before custom ROM installation is not needed, because old ROM(stock) gets deleted anyway and custom ROMs include root already.

LOL, well right now with locked BL its impossible, you have to unlock it.... its probably that in the threads already posted someone like me already said it
its most annoying having a locked BL - orangeUK did it to my device. waiting for an exploit or maybe ICS might do something. I have read that if you get the SIM unlock code into it, it may unlock the BL but I cannot say for certain, I may try this to see if it will allow the bootloader to be unlocked.
as for now we are stuck with a locked BL
Well, it's little off-topic, but what if we collect enough unlock code - IMEI/network ID pairs? If there is a database with tens or maybe hundreds of unlock keys, somebody smart enough can figure out the algorithm needed to generate unlock code to everyone.
Naturally nobody should post he's IMEI and unlock code in public. There must be somebody (preferably developer) who will collect those keys via PM or email.
What do you think about that?

If you never heard of bootloader, chances are you have bootloader locked. To unlock bootloader you need to do some manual steps.

Sorry, m8 that means it's network unlocked not bootloader unlocked. Wish it was easy as an app but only Exynos models are supported as of right now since their bootloaders are unlocked out of the box.
