Hi guys, I am newbie @ xda. I am having trouble with my I9300 and I could not find something useful on internet since months.
My I9300 was factory unlocked. I made a mistake while manual upgrading, I install Spain-Movistar sim locked 4.1.2 on my phone. After it my phone became simlocked. I could not solve this problem and I took it to a technician and I paid him. He does not say what he done on my phone and he unlocked it.
Now it is running rooted 4.1.2. He can not upgrade the phone to 4.3 because he can not unlock it.
Please help me I want my unlocked phone again and I want to upgrade it manually in future.
Thanks
Note: I manually upgrade to 4.3 but it locked again and I took it to technician, he downgrade and unlocked it same way.

Recently, I messed up real bad and I accidentally installed the firmware of a Verizon GS3 on a T-Mobile GS3. Now it is a Verizon phone :c I already rooted it so I can replace the firmware with a T-Mobile TouchWiz Stock ROM. All I need is the last step: to unlock the bootloader. Can someone (or anyone) please help me remove it? I am currently mentally constipated by the problem and I just have only a couple steps until I return it back into a T-Mobile Galaxy S3. Now that's the question. Here's the story of how it is what it is right now.
So one day, I was rooting my phone to install CyanogenMod because I wanted something similar to 4.2.1 Jellybean. I did everything except I didn't delete the Dalvhik Cache. So when everything was loaded, I see that my phone cannot open the PlayStore. In my mind, I reflect back a couple minutes in the past just to remember I didn't clear what I needed to. Idiotic me goes off and attempts to erase CyanogenMod 10 and I get stuck in a boot loop. I am in a state in which I call "mental constipation". I then accidentally and foolishly install the Verizon GS3 ROM and BOOM. I am in a worse situation. Fast forward today, I root the phone but as a Verizon Galaxy S3. I am almost done but I need to just unlock the bootloader and I am set to return it back into a T-Mobile GS3. So, can someone please tell me how to unlock the Verizon GS3's bootloader?
tl;dr turned T-Mobile GS3 into a Verizon GS3 and I need to unlock boot loader
Hey guys! I few days ago my S3 that I won off of auction came in and I've been trying to sim unlock it. Unfortunately GalaxSim Unlock didn't work. I noticed that for another method to unlock it I had to be under Android 4.1.1 or 4.1.2. Problem is that I can't get it to downgrade as it always bricks on me and goes into download mode. I've been reading around about this issue and I get mixed responses with respect to it being possible to downgrade. Has anyone been able to downgrade?
Also if I can't downgrade is there any other method of Sim Unlocking out there that I could try?
Have a samsung galaxy s1 i897 'captivate' from at&t phone.
Phone originally bought outright, didn't use for years, now trying to unlock so that a friend can use it.
First updated to the pacrom custom rom with kitkat 4.4 (is this part of the problem??) to test/be sure it would work before reenabling the phone. Got the unlock code from at&t - copied it exactly and it's FAILED now 3 times in a row, afraid to touch it with two left.
Is being under 4.4 part of the problem/does it have to have factory rom?
Asked some samsung people who suggested it may need to flash back to the original factory rom, but even thats not enough, mentioned "triangle" to "set back the clock" to pretend it's never been rooted or run a newer OS. Suggested it should then unlock. But also suggested certain Samsungs of this era were notorious for just not unlocking even with everything perfect which is why I was asking here before using up my last 2 attempts.
Does this all sound right/can only unlock the phone from the original factory ROM and OS version? Once unlocked when I update to PacRom/kitkat 4.4 I assume it stays unlocked or will it create a problem somehow?
If for some reason the last remaining 2 chances bite it, I assume this is what people normally mean by bricked and hopefully there's a recovery process or does locked to at&t forever really mean that?
Hi, guys. I have an SC-02G. And I'm from the Philippines. My problem are the docomo apps and the phone is still locked. I really want to get rid of them and get the phone unlocked here. So I researched for ways to remove the docomo apps, from what I've gathered, they all say that I have to root the phone and flash a new ROM. But I have no idea on how to do those things. As for the unlocking, I have to pay for the service of a technician to unlock it. But he said I have to downgrade to Lollipop first before he can perform the unlocking. I researched again but came up with nothing. I'm just a newbie. I'm really sorry but I need help from you, guys. Thanks!!!

So what I want to do is switch this phone to straight talk but want the att bloatware off this. If I install unlocked firmware and root the device would that make it unlocked? Like not carrier locked. Straight talk said I can already use a Sim despite it being locked but I wanna unlock it myself.
I don't think att will yet and not sure if they will at all. I'm converting my chapter 13 bankruptcy to a 7 on Tuesday and att bill is rolled into it so the phones will be mine once that is discharged but not sure if they will unlock them right after or if it will take months,that's why I'm asking this. I already reinstalled att firmware on this phone because I tried to install a custom room and messed up due to the bootloader issue of it being v5 I think.
