[Q] Questions about unlocking and rooting after Samsung 2.2 update

OK first post here. I have done a fair bit of reading and searching but still have a couple of questions. I have just bought a Captivate. Made 3 phone calls with it and that's it. It has already been rooted and unlocked by the seller. I know if I upgrade to 2.2 via KiesMini it will remove the unlock and root. After the update can I unlock and root again. ? I hear Super One Click might root it. I have the code numbers from the original unlocking. What can I use to unlock it? Thanks

you dont lose the unlock by updating it. even if you did, you have the code so it doesnt matter. you dont need it unlocked if you are staying on ATT....unlocking is so you can stick another providers SIM card in and use it on any GSM carrier

I am not on AT&T. I have an AT&T phone that's used on Roger's. That's why it needs to stay unlocked.

if you have the code then it doesnt matter if the unlock goes away.

Use the SIM you intend to use plus the code previously extracted. [APP]SuperOneClick v1.7 (Root, Unroot, Enable Non-Market App works on Froyo.

Update. Unlocked and rooted phone. Updated with Kies Mini to Froyo 2.2. Phone remained unlocked after update. Root was gone. Used SuperOneClick 1.7 and root was back. No problems at all.

[Q] has there been any progress on unlocking the bootloader?

So I just got my note 3 n900A att model about 2 months ago. last month the lollipop update pushed to my phone and I was happy but then I started working on rooting. I successfully downgraded my phone to 4.4.4 then to 4.4.2 by following guids on here and on another webiste that instructed me to use odin and then I rooted. Right now I am on Biggons rom and it is beautiful. I have been using safestrap to flash custom roms for this n900A.
I am however interested in trying to obtain a custom kernal and the bootloader being locked is frustrating. To my peasant understanding there isnt a option as of yet to get around the bootloader. please correct me here if I am wrong.
Are any developers working on this? Is it even possible to work on this? Am I just completed F'ed unless I went out and got a different variant of this phone with an unlocked bootloader?
lastly! Im curious if it is possible to turn my phone into a developer edition? that might be just a repeat version of my previous question. excuse my ignorance. I am new to this phone and boot locks n the what not.

Was bootloader unlock ever achieved?

[Q] Why doesn't exist any upgrade to android 6 or 7 for s4 active i537?

Hello community, recently I did the procedure to get the lollipop version in my S4 active i537 keeping root, but after many searches I can't find how to upgrade to marshmallow or nougat version and I wondering why.
I think it have to be because at this moment doesn't exist any way to intall a custom recovery as TWRP or CWM, if this is true, why nobody found the way to unlock the bootloader yet? in order to manage the custom recovery.
And why is so difficult to unlock it?
Which are the differences between this s4 version with the others? And how can I help to unlock the bootloader, thanks in advance.

I'm going to try to answer your questions one at a time:

There is not and never will be marshmallow or nougat for the i537. This is because it is outside the "2-year" update cycle of Samsung/AT&T. If you look at other phones from Samsung and AT&T, there are very rarely updates to phones 2 years after the initial release of the phone. There's not really a good reason for this other than Samsung and AT&T want you to buy a new phone to get the latest updates. In the past you would need to get a new phone in order to have new hardware that is able to run the latest version of Android. But we're now at a point that nearly any phone released in the last 2-3 years can run nougat with minor lag. Manufacturers and carriers are holding on to the 2-year upgrade cycle and forcing you to buy new phones in order to get updates.

The i537 has a locked bootloader while the i9295 does not have a locked bootloader. Nobody has figured out how to unlock the bootloader on any variant of the S4.

It's a very long read, but this thread explains exactly why it is so hard to unlock the bootloader. (http://forum.xda-developers.com/showthread.php?t=2500826)

As I stated above the only difference between the two versions of the Samsung Galaxy S4 Active (i537 vs i9295) is that the i537 has a locked bootloader and the i9295 does not. The i537 was sold exclusively through AT&T (US), Telcel (Mexico), and Claro (Uruguay), while the i9295 was sold internationally. Neither device will get official versions of marshmallow or nougat, but since the i9295 has an unlocked bootloader you can flash marshmallow and soon nougat custom ROMs. Other than the bootloader, the i537 and i9295 have identical hardware.

Honestly, unless you have a deep understanding of kernels, Linux, and cryptology, I'm not sure there's much help you can provide. The link I provided above explains all the effort that has been put into unlocking the bootloader. If you truly want to help I would read through that thread and see if there's anything meaningful you can provide.
Finally, if you don't ever want to have this problem again, always do your research and but a phone that has an unlockable bootloader. I purchased the i537 when it first came out only to find that the bootloader was locked and because of that I will never buy another phone with a locked bootloader again. Good luck.

Thanks for the explanation, what I will do is change my S4 for the international version in order to get the nougat custom rom.

[Q] Update N910T with stock firmware w/o updating bootloader?

I have an SM-N910T running N910TUVU1COG2. I've kept it at this because I didn't what to lose the unlocked bootloader.
Is it possible to update my N910T with stock firmware without updating the bootloader? I've done it on other Android phones without any problems, but am clueless about the Note 4's ability to do so. What say you all?

No you cannot run 5.1 or 6.0 firmware/rom with 5.0 bootloader.

Well, that totally sucks. Damn Samsung/T-Mobile. One of the main reasons I bought the phone was because it had an unlocked bootloader so that I could do as I will with it. It was bought out-right, unsubsidized, and I should be able to install what I want without worrying about the bootloader getting locked. So I guess I'm stuck at COG2 for a while longer, at least until my desire to keep the bootloader unlocked is overcome by my desire for new hotness.

Are you certain? I thought that past COG2 T-Mobile locked the bootloader.

If once you upgraded to marshmallow you can only downgrade to 5.1.1 OK1 but no 5.0 or 4.4.4.
But with 5.1.1 OK1 bootloader you can still flash 4.4.4 and 5.0 roms with custom kernels and they work flawless.

Only revert lock. But if you are looking at rooting, recovery and flashing roms its not locked. I took mine to PE3 MM and left it there.....

OK, I'm confused.
Sorry to belabor the point, but I'm confused. If the bootloader is unlocked, then should I not be able to flash any ROM, Samsung's or not? i.e. I don't understand how the OK1 bootloader, if it's unlocked, will prevent me from flashing COD2. Or is it that the bootloader itself will not properly boot anything prior to OK1?

TWRP and ROMs for Note N920A w/ Nougat

Can I install TWRP for the AT&T version with Nougat? I have heard that if I try it will brick. I'd really like to install a new ROM so I can get rid of all the crapware that comes with the phone.

The 920A At&t cant be rooted as of yet and no twrp because the bootloader is locked...

Bootloader
I recently talked to at&t about getting my bootloader unlocked and a supervisor told me the only way to do so without bricking would be to being it in to an at&t store and they will unlock the bootloader.. anybody else have this told to them?

They're most likely taking about a Sim unlock not bootloader. Also there is a method for rooting it but you have to be on a specific bootloader and you can only use it on lolipop.

Ya, I know about that root method. Unfortunately, my phone decided to update itself a few weeks ago and now its on BL 5. So that's pretty much a no go.
In relation to bringing in the store for a BL unlock, I did specifically ask and made sure the tech I was speaking with knew the difference between BL and sim unlock. In fact, i made it very known that my radio was already unlocked, I done that weeks before i talked to her.
