[Q] How to unlock a bootloader if possible? (N900A)

Heya, I'm very new in the vast world of Android rooting and flashing and I've run into yet another problem trying to flash my N900A Note 3 variant. I finally got it SIM unlocked and rooted and just when I'm getting ready to flash I see something about bootloaders. I don't know how to check to see if it's locked but I'm more than certain it is. So, is there anyway to unlock the bootloader? I see people saying it can't be unlocked yet I see guides for unlocking them so really all I'm looking for is a straight answer.
And if I understand it right, Safestrap isn't something I want to do if it's not the 'real' thing, so if it can't be unlocked then I'll be looking into another phone. If I do, would it be better to get another Note 3 variant or the Sony Xperia z1s?
Thanks in advance.

AT&T models are locked at the bootloader, and there's no way to unlock them.

I have similar question....I have 9005 version and want to put new bootloader.....I put new NF2 modem and now i want to put NF4 bootloader....
Is it enough just to instal it through odin?
(Searched for instructions but couldn't find it.....)
Thanks....

Okay, I have a few questions on this subject.
Safestrap is a work-around a locked bootloader right? If I use it to flash a rom would there be that much of a difference?
If using safestrap pretty much the same thing then why do people still prefer to have unlocked bootloader?
Because I see guides to unlocking bootloaders, does this mean that it's just AT&T that won't let us unlock this phone version?
Sorry for the questions, I just want this stuff cleared up.

You can't change the kernel if your bootloader is locked, so safestrap only works with TW-based ROMs -- no cyanogenmod our other AOSP variants.
AT&T is one of the carriers that forces the OEMs to lock the bootloader. I believe Verizon is another one. No other carrier seems to care, or have enough power over the OEMs to force this.

Root device

Hello does anyone know if it is possible to root the galaxy s7 edge, I have the AT&T and? Thanks for the help in advance

As of right now it there is no working root method.
The phone is fairly new and will take some time before it will be rooted.
I believe it took almost over a month just to get the S6 rooted, but since the S7 is fairly similar to the S6 it might not take long.

Unlikely the att will get rooted since it has a locked bootloader.

I thought with the locked bootloader you can root the device you just can't flash any custom Roms to it?

Sprint S7 unlocked: Is there a way to update it safely?

Long time reader...first time poster
I bought an unlocked sprint s7 from ebay and it works like a dream and i was wondering if there was a safe method to update the phone WITHOUT ruining the unlock that the seller put on the phone.
Current software is update PC5 and i would love to benefit from security and bug fixes in new releases.
Thanks in advance!

I always thought if a phone gets carrier unlocked it didnt matter what u did to it, it would stay unlocked. Unless the way he got it unlocked was thru a mod maybe that can b ruined. Im not sure

Most likely not a carrier unlock do to a unlocked padlock during boot animation as well as samsung pay not working due to software mods that im guessing made it unlocked in the first place. Thanks for the reply!

Bootloader unlock and sim unlock are two different things. You said it has an unlock pad on boot up screen. That means it's bootloader is unlocked. Which means if I am correct if it has a custom recovery you are unable to do future ota updates. Can and possibly brick your phone. You can flash a ton that has the new update no issues developers are usually fairly quick to update there rom on the latest ota.

Now my question is that since my phones bootloader is unlocked via custom software, would it be safe to root it and install custom roms that have the current updates? thanks

Yes! You are in the wrong forum though. You are on sprint but need to be with the enxyos forum ND running their tarp and roms

Have the same dilemma as OP.

Should i update OTA or leave it be.

I can confirm that updating over OTA will NOT screw with the unlock of the device. If your samsung pay does not work i would disable knox with a package disabler app to receive samsung pay in you new updated state.

OTA update from PC5 to PH7 on unlocked phone went smoothly.
Thanks

I have a unlocked Sprint S7 but im outside of America, is there any way i can update without losing the unlock? i don't want to end with an expensive brick.
Im stuck in G930PVPU2APC5 and i can't receive OTA updates

I bought unlocked sprint s7 that I'm using with metro PCS, but it's not letting me update the profile and because of that I'm not getting the wifi hotspot option. How do I get it to work?

@ThaDunder : You must initially do it manually over samsung smart switch then OTA will work @zirnitra : Sadly wifi tethering is not working for me either...no idea how to fix it =/ must be a symptom of the unlocking like wifi calling

I already tried that, smart switch says there is no update available.

Is it possible to root a Galaxy S7 (G930V)?

Hello Everyone!
I have a Verizon Galaxy S7 and I am wanting to root it! But when I tried it did not work so I just put stock rom file back on it. I read online that my boot loader is blocking the root? I did update to 6.0.1 and my version is G930VVRS4APH1
If anyone has achieved root on this device will you please share instructions on how you did it? Thank you

I tried this method, and then my phone got stuck in bootloop. I had to flash stock rom through ODIN.

Yes. and after 2 bricked S7's and a 100 rabbit holes leading me to who knows where, I finally got it.. give me a day or so and ill post the link and how to

The thread Sir_Eagle posted is the correct one for anything root. If something looped, then you either did not meet the prerequisites of the guide or did not follow every step of the guide. The bootloader on this variant requires every image to be signed, this is why the only root we currently have is via a SIGNED AND LEAKED engineer bootloader. Without this, there is no root on this variant. If you DO want to root, follow the link Sir_Eagle provided (but realize it comes with an outdated hacky kernel that has known issues), or go with stock. Up to you

That's still a U snapdragon variant (note Snapdragon 820 in specs).. Would be equally unlockable for the bootloader... "UNLOCKED" in retail sense means SIM unlocked, not bootloader unlocked.

I stand corrected. How would one obtain a phone (preferably Samsung) with bootloader unlocked?

Buy the European version of the phone with the Exynos processor instead of the US version with the Qualcomm one. Problem is that phone likely won't work with any of the carriers here in the USA. Or you could move to Europe.

Snapdragon variants aren't unlockable (exception being one hardware different model than ours). You can get an international samsung chipset variant with unlocked bootloader but not a US snapdragon one.

Thanks. I don't have to worry about that for a while, since I just upgraded. I don't like the idea of no root, but it is what it is. Guess I'll check the device recommendation threads next time.

A few other questions that occur (in case I add more devices to my account or pick up an additional service):
1. Aside from an international there a (quality) phone/brand that will allow rooting in the U.S.?
2. What caveats can be expected when using an international device (presumably, I can get one compatible with whatever carrier I choose)
I guess it's conceivable that I could buy one of these 'rootable' phones and either add it to my Verizon acct or replace one of my current lines.
I miss root, particularly the ability to create nandroids and Titanium backups. Oh, and accessing the entire file system.

I really hope that you just didn't do it right cause I just got a G930V and if I can't root it will be immediately RETURNED
No root is an absolute DEAL BREAKER.
I see rooting threads so I hope it works.

S7 edge sm-g935p twrp?

I read a twrp release thread that said it wasn't possible because of locked bootloader but i wanted to verify, is there a twrp for this phone? Definitely dont want to do anything to this phone without a good recovery option.
Thanks.

If you have a exynos version yes.
Snapdragon version no.
Sent from my Note 7, S7 Edge or S6

No g935p is snapdragon.
Any working custom recovery works for it? Got a samsung s serries phone because i loved my s4 and it had tons of supply for it, with twrp it was virtually impossible to screw it up, bricked a couple devices before. One without even modifying anything and with stock recovery was left dead in the water.

There is no custom recovery or toot of any
kind for the samsung snapdragon phones.
There are three good places you can check out where
you can sell that phone, Ebay, Swappa and Offerup.
You need to buy a international exynos model samsung
galaxy phone if you want root, custom roms and features.
Good luck,
Have a great day!
