Locked Bootloader - Galaxy S III Q&A, Help & Troubleshooting

Hello,
so a friend of mine just bought an s3 and he wants to update to JB, but hes on a different carrier than i am
and im 90% positive his bootloader is locked - any way to verify this? so i can then root him and flash something pretty on his phone

you dont have to root to flash JB, only if you want a custom rom.
Just flash a JB rom on his phone using odin

[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

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?

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 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.

[Q] XT910 current status? (Sim Unlock? Custom ROM? Root? ISC?)

Hi! I might buy the Rogers XT910 in Canada in a few months... and I'm actually kind of confused... some posts say it can be rooted, some others no...
I'm also confused with "loked bootloader" thingie... I have a Samsung captivate now.. I can flash any rom whenever i want... can ithis be done to this phone? ISC?
And the most important thing I need to know... I couldn't find any Sim Unlock method.. is any avalible that you know?
Thanxs!

1. Theresn't any unlock method as Galaxy_S unlock app, or anything like this. You'll need to buy your code. gsmliberty.com is a good place to get it.
2. You can root your device easily.
3. You cannot flash any rom, this is a locked bootloader effect. (by the way, you have not too much option of custom roms in razr as unlockes bootloaders device have, like the samsungs...
Wish you luck on razr. Cheers!

[Q] A Serious Problem For Me

Hi guys,
i bought my sXs two days ago and i just love it !
After i bought it,i directly unlocked bootloader. And wanted to root.
Because there were a lot of useless stuff in there.
While trying to root,
i had to flash Europe Central 1 ROM (pre-rooted)
Now im really happy with my phone.
BUT,
If i need warranty, i think i will need it because sometimes i see yellowish things at bottom of the screen.
I know i can relock bootloader. But how can i get back to my country's ROM?
I mean they will probably ask me, yes bootloader is locked but where is our /useless/ apps ?
I have friend who also have same ROM ( our carrier's rom ) and i can get files from him.
He didn't unlocked bootloader but in 1-2 weeks he will.
How can i make a backup file for that ROM ?
I couldn't Flash Doomkernel with Stock ROM because there is no recovery mod in stock kernel. (or im doing something wrong )
This is really important for me.
Sorry if it is wrong section.
Thank you for reading.
Best Regards.

To reflash your phone with your country firmware, do the following:
- lock your bootloader (there is a guide in development section)
- using root explorer, edit the build.prop inside /system
to change ALL CID back to your original firmware numbers. CID number can be found here
http://forum.xda-developers.com/showthread.php?t=1557148
- reboot phone (must). run sony pc companion, and choose repair phone firmware... it will install the firmware according to CID your have on your buildprop
just a note: the new version of sony PCC won't let you update/repair if you have unlocked your bootloader. so the change if bricking is less.
i have successfully done it.
Don't bother. They replace devices with yellow tint just fine no matter if unlocked or not. They know it's their problem huh

N00b - question

I've been reading all day, yet I still don't have it quite clear.
My phone can not unlock the BL, therefore regardless how many firmwares I will flash it I won't be able to remove branded apps, right? because I need it rooted to remove the apps I don't want.
On the other hand, If I get a code to remove the sim lock when the time comes and the BL may be unlocked, will I be able to unlock the BL, I read in a post something that confused me regarding unlocking the sim by a code from a internet provider, but don't remember where.
Thank You
I got mine networked unlocked and the bootloader is still locked. From my understanding it does not change it to yes by unlocking sim. I have only seen 2 people who said this method worked for them compared to the dozens that tried with no luck.
the only way to have your xperia rooted is through the unlocking BL and flashing rooted kernel or rooted system.img at this time. I suppose in the future there will be more options of doing it, so maybe that will solve your problem of locked BL.
i don't know if there is still the testpoint method for the xps.. but if yes you could try that .. should work afaik.. and if not then just wait for another root method

nope in the xps dosen't work, but i think if you connect the unused usb pin 4 and 5 with a resistance of 301k may come with something, idk if it works becose the 301k is hard to find

I have done already, two actually, the CE1 Generic and the NL Generic(because I heard of the speed).
Before I flash them I got from Antutu 6580
When I flashed the CE1 lower to 6520
And with the NL 6460 and now is 6634
But still some of the apps that came with the phone are still there, seems like the only way to get rid of them is only rooting.
I can't wait to get a way to do it.
By the way does anybody knows of a North America firmware for the LT26i, I can not find one. I live in El Salvador and I want my phone with a firmware for Latin America or the States, main reason is Google Voice another is that if I want to buy something from the Google Play the prices appears in Euros €.

I use unlocked phone, but I guess you can go to sonymobile.com and use sony bootloader unlock to get a code for unlocking your bootloader, although since u have a branded phone you may need a code from your career. when you got the code use fastboot to unlock it. other than these, if you just want root, flash your phone with flashtool to any rom you like. you dont need any bl unlocking for this and you still get the updates from sony. you dont even need any code from career or sony. since xperia S is new there might not be any prerooted rom so be patient and let the xda developers play around to find a way.
Hello, the code desimlockage operator does not allow unlocking

Antutu ratings fluctuate hugely on their own, test three times in a row and you probably wont get the same result each time.
Use Quadrant as your standard
I think you should wait for another way of rooting

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.

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).
