[Q] How can I unlock my bootloader on I747 running 4.1.1 with a mac

I have a Telus version Galaxy s3 running 4.1.1 and I want to unlock the bootloader and root the device. I need to know how to check if it is unlocked first of all and then if it is locked I need help to unlock it and root it. Keep in mind I am running a macbook and would need instructions for that. I have tried google but have not found proper solutions to it. Any help is appreciated. Thank you
PS if there is already a thread about this then please send me the link
Thanks again

SGH-i747 devices come with an unlocked bootloader out of the box.

My apologies, just realized you said Mac. The above guide can be followed but instead of using ODIN you would use Heimdall to flash. Heimdall is cross platform compatible with Linux, OSX and Windows
Link: http://www.glassechidna.com.au/products/heimdall/
Please do some research before you start flashing with Heimdall. Just like ODIN, if you do not flash properly you can end up with a brick.
NOTE: the below guide is for the d2att. If you have a different device let us know or search. Using the below on a non-d2att device can cause complications leading to a brick.
Below is a link to instructions on how to flash CWM custom recovery as well as how to flash CM10.1. Its a good guide and walks you step by step through the instructions. Once you have the custom recovery in place you can flash any ROM you'd like. AOSP or TW.

Thanks. I will take a look at it more tonight and see if it will work, What I am looking to do is root it and flash a custom rom of a 4.2 on here. I also want all the Samsung bloatware gone.
My phone is a koodo phone but it is the same as the AT&T version from my understanding so hopefully this works and I can install a good upgrade to it.

It is Koodo but from what I understand because Telus owns Koodo that they are essentially the same. I know without unlocking my phone I can put a telus sim into it and it works.

You could drop a Telus SIM into the international version, and it would work. Maybe not on LTE, but you could make calls and get data. The best way to confirm the model is through Settings -> About device -> Model number...

[Q] Sim Card Isn't Detected

Hello XDA,
I've been having this issue with my sim card since right after I flashed the latest CM 11 nightly (coming from a previous version). I just updated my bootloader and switched from TWRP to CWM earlier today. I had flashed the new nightly and after it asked for the system language, I received a pop-up window telling me to review my sim card instructions. This hasn't happened to me before, so I am extremely nervous and have been searching the web/forums for the entire afternoon with no such luck at finding a solution. I finally decided to make an account and post this thread with hopes that someone will be able to solve (or at least point me in the right direction to solving) my sim card error. Sorry if the answer is very obvious and I had missed it or something, I'm in a state of panic to be honest :crying:
Any help is greatly appreciated.
EDIT: I found a few links to a site for unlocking the network, but is this what I am looking for? I want to be 100% sure before I do anything risky. (I can't post the link because I am a new user :/ )

Did you update to the 4.3 bootloader? Which phone do you have?

Click to expand...

The bootloader I have installed is I747UCUEMJB. I assume it is sufficient because it was the latest one that I found available that worked with flashing the CM 11 nightly. My model is SAMSUNG-SGH-I747 by the way. The carrier is at&t. As some additional information, I've also tried restoring to the backup right before the rom flash that started my sim card errors and it didn't fix it.
EDIT: Also just found out that my IMEI number is "unknown". I tried entering *#197328640# into the dialer, but I didn't get the network menu (maybe it was taken out of CM 11?)

Sorry for the double post. Just realized that it might be a 4.4/4.3 issue rather than CM 11 as for not having the dial pad menu. Are there any ways to generate a new IMEI based on the one found on my phone's label, and if so would there be a way to flash it onto my phone (did the connection menu in the dial pad get moved somewhere)? I wasn't aware that this scenario was even possible for the year or so that I've been flashing roms, so I'm coming to terms with having to buy a new phone

Thank you, this is exactly what I need! My only problem is that I can't seem to figure out which COM port I need, I'm searching that thread to find an answer but no such luck yet.
EDIT: Sorry about that, just connected successfully, yet when I write it over I am getting an error that says the phone is not answering. I skipped the *#7284# step due to the 4.4 dialer not launching the menu, and instead I tried using the Diag method but it gets stuck halfway through and doesn't finish the command. Any ideas? :-/ sorry to be such a bother and thank you for your time
EDIT 2: I guess an option would be to downgrade to 4.3 somehow so then I can use the *#0808# code to access the menu. I'm not entirely sure if reverting from 4.4 to 4.3 is safe though

[Q] Stock Firmware

Hello everyone i am in a peculiar situation i recently got s3 from my friend he said that it is I9300 but when i received it i came to know that it is T999 and not I9300 . My problem here is it came with android version 4.1.1 build number : I9300ZSEMC1 i didn't understand why it came with i9300 firmware ( i cannot ask my friend as he does not have much technical knowledge ) everything is working fine occasionally touch does not respond and i have bit of hard time switching on wi fi and weird battery drain problems what i want to know is , is these because of the i9300 firmware being present in t999 and whether is it advisable to update it further from 4.1.1 version to t999 latest stock firmware or to stick with the present version . If it is advisable to update to t999 based stock firmware i want to know whether it will work in indian carriers and wont have any problems and also can someone guide me for the right firmware link / build number to go with. :fingers-crossed:

I didn't know the firmware would actually flash across models.

Isn't the I9300 the 1gbp ram version?
Anyway, if certified in download mode you could just flash t999 firmware.
If that doesn't sound safe you can also put a t999 recovery on it and try doing a backup and installing a t999 rom

Sounds kinda like some of the "frankenphones" we've heard about over the last several months. Or it could also be a fake/chinese knock off. If I were you, I would see if there were any way to send it back to whoever sold it. If you plan to keep it though, understand anything you do is AT YOUR OWN RISK! The only absolutely safe course of action is to do nothing to it. If you try to flash it via Odin, and it allows it to flash, but you chose the wrong firmware, it WILL brick. There is honestly no possible way to know for sure what is up with the device.
If I had to guess, something is lying to you about what you are running. If your current firmware version is from an I9300, then that is most likely what you have. That firmware WILL NOT work on any Qualcomm, US model S3's. This tells me that its probably an I9300, and someone screwed with something, (or was careless when trying to copy Samsung), in the bootloader. Because it tells you it is a T999 in download mode, it will probably not let you flash the I9300 firmware. But if you try to flash the T999 firmware, there is a very good possibility you will brick it.
It is up to you what you want to try, but understand you are taking a bigger than normal risk since you already know the device isnt normal to begin with.
One way you can try to determine what motherboard it uses, (though this is by no means a for certain way to know), is go to the SIM unlock thread in General and try to follow those instructions. Also try the GPS fix thread in the Q&A sticky roll up. If I am not mistaken, both use dialer codes that are specific to Qualcomm devices. If they work, its a better chance of it being a T999. If they do not work, its more likely to be an I9300.

[Q] Upgrading Samsung SCH-I435 to Android Lollipop

I haven't found any information for my specific model for some reason.
What I want to do is install stock Android 5 (by stock, I mean what comes on the Google Nexus) on my Verizon Samsung s4 mini (SCH-I435).
To my knowledge, this would involve:
Rooting the phone
Finding a compatible ROM
Flashing the ROM
I just can't find any guides or ROMs for my specific model. Can anyone here help?

I have the exact same model of the s4-mini as you do, and I've looked around just about everywhere. It seems that the bootloader has never been unlocked for this variant of the S4-mini. Verizon also just released a new firmware update that patches the kernel, preventing the use of previous root methods, and it may be some time till someone finds a way around it. If you find anything, please tell me, as I can't stand this bloatware crap on my phone.

How do you usually unlock the bootloader?

Click to expand...

Usually people create software, such as Cyanogenmod, that exploit vulnerabilities in the software on the phone, giving them access to the bootloader. One of the many issues with this variant is that it is distributed by Verizon, and Verizon is very vigilant about patching vulnerabilities.
EDIT: After a little more digging, I found that the bootloader is completely locked and there is a 99.9999999% chance that it will never be unlocked, typical Verizon for you.

Correction
You can root the SCH-I435 with towel root, install SuperSU and Busy Box from Play store. Then flash phils touch recovery and then flash a rom from SD card in recovery. Beware, if you are on Bluegrass cellular. Any rom must be for CDMA phone for the SCH-I435.

Where would I find a compatible ROM?

I have been looking too. Tried a couple, but lose phone service. Everything else works.

Definitely not legit. They simply have tons of links on their site to upgrading every single phone to lollipop. Inside of each page is exactly the same link to the same "ROM" for every phone, and the comments at the bottom of the page aren't actually real, they are just a picture. Try changing the number at the end of the link "...updateupgrade_70.html" and you will see what I mean.

I was able to successfully root my phone by flashing 4.4.2 NE1 (opposed to the latest version) via Odin and using Towelroot.
Has there been any progress on the addition of a custom recovery?

I found something interesting that might be worth looking into. This guy (http://forums.androidcentral.com/samsung-galaxy-s4-mini/527518-serious-question-needing-advice.html) claims to have installed a custom rom that was designed for the GT-I9195 on his SCH- i435. I have actually run into him before on other on some other threads and he seems to be legit. But the problem still remains that when he installed the rom his sound and mic didn't work. Still worth looking into though.

Just curious, would over of the international variant ROMs work if we managed to unlock the bootloader or would the SCH-I435 require its own specific one?

I found an app called Flashify that claims to be able to flash a boot loader or recovery to your device from your device.
Do you think flashing CWM or TWRP would work this way?

It seems that the only thing that this has to offer for us is a way to flash your phone without using a computer, and to back up your phone (I haven't actually tried restoring from a backup). But we still need a version of CWM or TWRP that is made for the sch-i435.

[Q] I am trying to unlock T-Mobile S4 from ebay

So, I recently bought a galaxy s4 from ebay, and it seems to work on the network, so I don't think the IMEI is blacklisted. However, when I tried the steps here http://forum.xda-developers.com/showthread.php?t=2282683 and here http://forum.xda-developers.com/showthread.php?t=2283068, I am unable to complete the process. When I do the latter, which seems more like what I did with my S3, I get the same message "unable to process request". I remember I was getting this message on my S3 when I had the SlimKat ROM on it. But when I look at my S4, it looks like it has the OEM ROM on it, so I am not sure what is happening. I looked at my boot loader/baseband, and this is what I have: m919uvufnh7. I know that with my S3 I had to make sure I used the correct ROM to flash my phone, so I could get it unlocked the free method. So, does anyone know what bootloader and ROM could help me accomplish these steps in the second thread?
I am thinking I should flash a different ROM on my phone.

Thanks for the response, but I have not tried it, because I don't think it is that easy. I also purchased AT&T tablets and tried unlocking them, but AT&T said they were 'active' under someone else. They were not not showing as stolen, but active. I am not sure what that entails, but I am guessing I have to register it under my account first, before I can request to unlock it. So before I try going through the long process of figuring out how T-Mobile can unlock my device, I thought I would give this a try. It seems simpler and since I plan on modding my phone after I unlock it, I see it as just part of the process. (At least I hope so.)

Alright, I was able to get mine to work, so maybe I will list my steps. However, I must say that I had some failed attempts (in part due to not understanding the post referred to by radoo7701) and some issues with my phone. But those steps wont be included. Also, my version was m919uvufnh7, not NK2. I would think it does not make a difference, as long as you reflash back to NK2 at the end.
1. I locaed the modem for M919UVUAMDL and m919uvufnh7 modem (as I did not make a backup of mine before starting)
2. I used Odin 3.07 to flash the AMDL modem
3. I tried the steps here http://forum.xda-developers.com/showthread.php?t=2283068, but this would not work, I could not even get the menu to pull up, as it would say request unable to complete. So I tried this http://forum.xda-developers.com/showthread.php?t=2282683 and that actually worked, so I went through these steps successfully.
4. Use cf-auto-root to root your phone
5. Download regionlockaway and transfer it to phone, then install it on phone and run it.
6. flash m919uvufnh7 modem and booted up with my AT&T sim, and it did not ask for unlock code. It just worked!
NOTE: I did have to use a T-Mobile sim card to do the menu process, but radoo claims that he did not do the menu portion. I had already done the menu portion when I finally got to reading his comment. So I can't say that it will work or not. Either way, his suggestion worked for me and I am content with the result!
Thanks radoo7701!
