[Q] Need your help to understand this about bootloader!! - Android Q&A, Help & Troubleshooting

When I turn on my Samsung Galaxy S4. I see a O2 screen after Samsung Galaxy S4 GT-I9505 screen. Does that mean my Phone bootloader is locked?
I am not using O2 sim card but another company's.
I have rooted TW 4.2.2 (Stock) Using Odin CF Auto root.
Also I installed CWM recovery Using an app from Play Store called "Rashr".
Looking forward for an early response.
Because I want to start using custom roms but someone said unlocked bootloader is must for that.

[Q] How to downgrade to 2.3.6 from JB 4.1.2 to simunlock?

Hi all!
Well, my problem is that I can't do the sim unlock and I think it is because the phone has 4.1.2 and a rooted kernel.( the phone isnot mine,owns to one friend)
I've been trying with the 2 most popular apps : Galaxy s2 sim unlock by chainfire and odia, and galaxy s unlock (this I think no root needed).
I'm thinkin that I can't unlock it because the kernel is not the official one. The phone is from Orange (Spain) and yesterday i was trying to flash the original firmware downloaded from Sammobile and it crash, so I had to flash a kernel (ApoloJb) to make it run again.
I am crazy to get the unlock sim... because If I get the sim unlock my friend will give me the S2
Thanks and sorry about my english :/

You need to report your post and get it moved to the verizon s3 forum. This is the i9300 international version. Anything you flash from here will brick your phone plus the i9300 does not have a locked bootloader.

[Q] Bought an unlockedGalaxy S5 ACTIVE SM-G870A ATT.

Hello ALL,
Got a great deal on a new Galaxy S5 ACTIVE SM-G870A. Was wondering if I can root and load t-mobile roms on it.
Noob at this bootloader but can I ODIN tmobile firmware on this like baseband and that would give me an unlocked bootloader? Then free to flash whatever ROM? I am not worried about the KNOX at all.
TIA.

[Q] t mobile gs5 rooted and unlocked, will stock rom remove carrier unlocked

hey everyone, I don't post much but I read a lot and I appreciate everyone's work. I have a quick question regarding my tmobile galaxy s5. I bought it and unlocked it to use on AT&T because it has the unlocked bootloader. I installed twirp, remove some bloatware, and it's been great. I want to remove twirp but I believe that flashing the stock rom is the only option. Is this true? I have the stock image and can flash it via Odin I'm just curious as to whether it will remove the carrier unlock. of course I paid for the unlock code and I don't want to do it again. I would like to sell this phone with it being unlocked because that widens the market. so does anyone know how I can unroot this phone other than flashing the stock image, and if that's the only way after I do it will the carrier unlock still be there?
Galaxy s5
Galaxy tab pro 8.4
You will keep the unlock. You can easily find the stock recovery files as well. That way you don't lose all of your stuff with a full Odin flash.
