[Q] how to unlock galaxy s4 from straighttalk SM-S975L

So I looked everywhere and no one seems to know how to unlock a straighttalk s4
since this site the best with cellphones problem solving I'm askin for some help :/
its a SM-S975L

when i ran the network unlock tool it was already unlocked the boot loader wasn't locked either the only thing we need now is rom development to include our devices. I have twrp and used towel root to root the device.

I'm dealing with this same issue right now. Bought an SM-S975L for straight talk last night and I want to use it on Metro PCS. Metro says all is well on their end and I just have to wait, but all I see is "Invalid Sim" on the status bar. How did you unlock the SM-S975L? There's very limited information around the internet about this model. I'm tearing my hair out and the wifey is driving around without a phone. Figured you (or anybody else) could point me in the right direction.

LOL, the $249 deal was hard to pass up. I got a couple of them, one for me and one for the misses. She'll be fine with the 4.3 that is on the phone out of the box, but I wanted to convert mine to be like the I9505G (GPE). I was thinking it would be simple as I've heard all of the LTE models were like the I9505 and they seem fairly broken into. But I think this is more like the SGH-I337 and maybe boot loader locked, but looking into ways to test that. I did root it already using towelroot. Installed SuperSU and Titanium Backup and root is working, now so see if I can get CMW and a GPE rom on it. If I find a way I'll be sure it is mentioned here as a working method for the SM-S975L. I'm not using it yet as I have my GT-I9500 that I'm using, but seeing better support for the qualcomm for custom roms I decided to get it. The I9500 should get Android 5.0 official rom first though.

For what it's worth, I just picked up this phone from the Black Friday sale, and I would *really* like to put a custom ROM on it. I won't even pretend to be proficient in this. How difficult would it be to convert the custom ROMs on other models of Galaxy S4's to this one?

I am unsure my self the closest variant is the att s4. Both the att one and this one is bootloader locked. Since we have 4.3 version of Android safestrap would be likely what to use. I am afraid of this my self so I have not attempted it

Whoa whoa whoa. What am I looking at? It looks like that's the model of the T-mobile variant, but the baseband is the same as the S975L!?

Even a custom kernel flashed! What.
Sent from my SM-T310

It is the SM-S975L with a T-Mobile ROM and the custom kernel. The SGH-I337 ROM does not work, it erases the system partition every flash.

Awesome work aromerblz. Anything special you had to do to load the ROM with the S975 baseband...or any issues you're experiencing? Will be testing this out later in the week when I get some free time.

That is cool, at the very least its Kit Kat. I still would like to find a method to convert completely to GT-I9505G. Just no time. I'm hoping with jtag access it can be completely reconfigured, then just make sure the IMEI is set to that the device should be. Ideally the only way to see it was a SM-S975L would be to look under the battery. I don't really care about removing the SIM lock though, I plan to stick with my ST SIM. I did get a new BYOD SIM and it is showing 4G now (Not sure if it should indicate LTE like old ATT S3 does) as my old BYOD SIM would not and ST support said that I could not move the included SIM to any other device as it would be bound to the S975L.

I would love to get off the Tracfone ROM. I'm going to assume that Samsung/Tracfone will never upgrade this phone beyond Android 4.3. The last native update was in February of this year, and it was just a minor patch. I'm not too concerned about unlocking, but being able to use a different ROM seems to be a step in the right direction. If anyone could post a tutorial or what ROMs they used, that would be extremely helpful. I've looked everywhere and this info is not available anywhere.
For what it's worth, someone over on GSM Forums has claimed to have flashed the AT&T ROM too. They also were unable to unlock it, however. Unfortunately, I can't post the direct link until I have hit 10 posts That poster has been inactive for two months, and before that, he was inactive for three years. It may be hard to get in touch with him..

I first flashed a T-Mobile TWRP recovery v27.1, but the latest v28 works fine. After that i downloaded the TMB firmware NB4 from sammobile.com created a custom rom with the android kitchen. After that the usual flashing of the rom via TWRP. Without a custom kernel the phone does not boot up. So i used the ktoonsez kernel. Once booted i rooted with towelroot and pjone has been working fine. Only things to know is that when booting up it says "Kernel is not SeAndroid"
"Set Warranty Bit: Kernel"
As that specifies it trips the knox flag. Which i dont care if it does as am not in the USA.

You used the TWRP for jfltetmo, correct? Did you use Odin to flash it?
Also, this might seem obvious, but even if I do this, it'll still work/remain locked to ST/AT&T, correct?

Yeah TWRP for jfltetmo. The jflteatt does not seem to work at all on this model. I flashed with odin, no need to use safestrap on this phone as i think the bootloader is not locked like the one found on the SGH-I337, although its the identical variant.
Yes the phone remains locked to ST/AT&T. A friend of mines was able to get the unlock cod for this phone but even with the unlock code its not a permanent lock. Reason is because you can unlock and be able to use all the features available to the phone but once restarted it asks for the code again. Not sure why it does that, I believe the radio has to be the culprit for that here. Not sure how TracFone will handle the unlocks for this phone after 01/01/15. does the same even on full stock TF firmware.

Can you PM me that GSM forums link you are talking about. I want to take a look.

Np, just a sec. (building up my post count)

GSM Forum stating AT&T-based ROM...not much detail I could glean from it tho. http://forum.gsmhosting.com/vbb/f286/unlock-samsung-sm-s975l-tracfone-straighttalk-1866981

Difficulties after switching to T-Mobile

Hey guys! Thanks in advance for any help or clarity you can provide.
I had to switch to T-Mobile from Verizon. My device isn't rooted, modified, or in any way different than factory. However because of the switch I've had some functionality that I've lost. Namely the ability to get software updates. This phone has been rooted before, and I'm very comfortable with the process of loading up different software. The question I can't find anything on is whether or not installing the T-Mobile firmware will brick/cripple the device. I know there are different chipsets so I'm trying to figure out the best way to keep my phone up to date without being on Verizon anymore.

You can flash T-Mobile's firmware or the U firmware without any problems. There are tutorials here in the forums that will walk you through the process.

I tried finding something about loading the T-Mobile firmware on a Verizon device but I haven't had any luck. Only guides on doing a regular firmware update on a T-Mobile device. Should I be worried about the Exynos/Snapdragon differences? I hate asking for something so simple, but could you please point me in the right direction? I'd LIKE to try and go that route, because the U firmware had poor battery life, a lot of heat generation, and requires a patch just to get wifi to work. Then again maybe I'm thinking of the eng boot we had for rooti. I do love my all day battery quite a bit.
Thanks in advance.

T-Mobile, Verizon, and the U phones all have snapdragon processors. No need to worry about that.
Read through this thread here as it pertains somewhat to what you're trying to accomplish. Read it from start to finish so you don't miss anything important.

@Outbreak444 Thanks for the help. Last night I threw G935U-PI3 on the phone and literally everything worked out of the box. Even wifi calling and (seemingly) VoLTE. It's taken care of all my issues. I can't get over the fact that it's now an out of the box solution and it works flawlessly.

Hey, a friend of mine just got the Verizon s7 edge and is trying to get it to work on T-Mobile. Did you have to get the phone unlocked somehow, or did you just install the U firmware and everything was fine. My friend's data is not working. Thanks!

Just look on the forums on flashing either the U firmware or T-Mobile firmware using Odin. It's a fairly easy process if you read through the steps thoroughly. And you don't need to worry about unlocking anything.

I'm familiar with flashing the U firmware, as I did this on my Sprint s7, but my understanding was that just flashing the U firmware didn't open up the bands. But are you saying that flashing the U firmware alone was enough to get TMobile fully working?

My understanding it does. The hardware between the phone's should be the same so it's software that's affecting it. But the U firmware won't allow wifi calling and other carrier specific things unless you're rooted. So pick and choose.

Rooting Galaxy S5

Hey All:
This may be redundant, but I'm having a hell of a time rooting my friend's Galaxy S5. I've got "developers options" on the phone, but every app I've D/l to the phone has failed to root it.
Here's the phone's SPECS : model no# SMG900A build no# MMB29M.G900AUCS4DPH4. I just now gave him a SDD micro card to install. What do I have to do to get his phone rooted? Oh, have NOT tried to root phone via a PC. HEEEEELLLPPPPP!!!
THANX:

G900A cannot be rooted

usmanmalik:
One should KNOW what he/she is talking about prior to replying. FACT: You most certainly CAN root a GalaxyS5. Just look at all the video/websites explaining how to do so. My problem is finding an app that will "root" straight from the phone. I may have to use a PC to accomplish root, but rest assured, it CAN be accomplished

most of us do know what we're talking about, you? idk.
by saying a galaxy s5 can be rooted assumes you know that there are no variants, sad to say there are.
the s5 SM-G900A is att version, locked bootloader, its the s5 no one supposed to buy, its a pia. owners of the SM-G900A are sol.
read this on latest rooting effort for the SM-G900A https://forum.xda-developers.com/att-galaxy-s5/general/guide-merry-christmas-heres-t3516196
did i mention the g900a is a pia to its owners wanting root? gl

Vincon:
I typed in said model and was directed to many sites that, according to those sites, could/would root via using a PC. This is in direct contradiction to your reply. Now, I'll have to keep 'researching" and actually see what's going on. Just curious...why would this particular model be the ONLY one that wouldn't root. I'll be sure to check on the "complaints" registered by the owners of the G900A.

ask AT&T, thats the way they ordered their phones which is the g900a.
the g900a is spec'd only to AT&T, there is also another variant thats also locked iirc.
read the link i posted as it seems its the most upto date root info for the g900a at the moment afaik.
the g900f is the one u want and its cousins, the g900w8(mine) is one of them, known mostly as international, these 2 models have unlocked bootloaders making it very easy to root via pc, idk about an app rooting though especially for 6.0.1
many do come w/unlocked bootloaders but not the g900a as thats the way the carriers(AT&T) ordered them w/locked bootloaders.

Since reading the link you posted, I'm not sure what you're trying to convey. Reading the link seems to indicate it can be rooted! (?) I did note that it said it wouldn't 'persist", but in the 'replies" one person stated he/she did get it to work? OK, at best, we are going through hosts of opposing and controversial statements? Could it be that by now, there is a viable 'root" for this phone? Also, I did see where some 'downgraded" in order to root. Not sure I'd do that...especially since it's not my phone. Anyways, seems this model will command much more of my attention than I first thought. I've rooted phones before and was "spoiled" by the simplicity. Never run into anything remotely similar to this.

im trying to convey is that its a pia to deal w/the g900a because of its locked bootloader as you must of assumed reading that link i gave you, and that is the most upto date info on rooting the g900a and afaik no root possible for 6.0.1 mm as i just quickly read through some of the posts in that link.
what youve read on the internet on rooting the g900"A" as easy is either old, false, inaccurate etc.

Bootloader is Unlocked?
You try to flash TWRP Recovery using odin?
https://dl.twrp.me/klte/
(If any problem, You can download latest firmware for G900A in your region, Unpack with 7-ZIP the Recovery from firmware file and flash via TWRP)
And Flash SuperSu via TWRP?

LS99720a - Any way to root JUST for deleted file recovery? Don't need other stuff.

Title. I no longer use this phone but I would _love_ to be able to get deleted stuff off of it. I did this in the past with my old LG G3 and never had any issues like this phone has with getting to root. I tried it when I first got the phone, tried it a year later. never worked. Now trying 3 yrs lol. Is there anything I can do or am I SOL?

@Phoenix591 already answered this for you on Reddit. I don't know what else to tell you.

Original Reddit post for anyone else who is reading
Thats an Oreo version, and so is past the point of no return. It's unrootable. Tiny electronic fuses have been physically burned to prevent it from booting rootable firmware.
As I mentioned the last version that has the ability to return to a rootable version was ZV7 (the actually rootable versions were ZV5 or earlier, however LS997 did updates weird which ment that firmware wasn't available to flash using the same tools other models use... If on ZV6 or ZV7 its possible to root by crossflashing another model's firmware briefly ) , which was a few updates before oreo came out.

Unfortunately, the LS997 ended up being more limited than the other carrier-specific models. However, root access is getting harder to come by on new carrier-specific devices in general.

Help with Verizon S10+

I am trying to root my Galaxy s10+ that is with Verizon. The model is SM-G975U and CSC is XAA, I wanted to know if it was possible to root the one I have. The only reason I ask is because almost every guide if for models that are different and the ones for this model are really old and it seems peoole have a few problems trying. I just need to know what is everything I would need to download to get it rooted, Ive included some screen shots of some device info. Thank you for your help!

you cant root as its not available.
