[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.

You can't downgrade from aph1 the latest update updated the bootloader. But you can still have data, messaging,etc with the aph1 update just takes a bit of tinkering.

I'm currently running the 930u firmware and love it I have my Hotspot an all. It's a completely different phone now. First few days of my s7 I HATED it. My s5 was faster no joke, I don't know what sprint did with their bloat but it's a different phone without it.

That's what I came from was 930u latest firmware it is pretty amazing compared to 930p. I just really missed adaway and a few other things. I had a s5 with unlocked bootloader before my s7 and yes my s5 was way faster than my s7 fresh out the box.

LOL I didn't notice how much Adaware did until I didn't have it.
There are a few things more im missing but 930u is a huge step in the right direction. I need to do more research I guess been years since I've had to root a device I almost took this thing back an went back to my s5 after the first day.
I know about Sam Mobile but it's links are super slow unless you pay, I was trying to find a decent free link.
I don't even need a custom rom I'm stoked on this one as is, I'd be happy with this an xsposed modules.

Well I had a hard time getting the LTE and messaging to work with root. 930u when I rooted I could not change my apns I couldn't add new ones either. I tried using ##data# to go in and fix my apns that way but I needed my msl which sprint refused to give me. On sprint firmware tho all u have to do is go to build prop and change ro.cdma.default_alpha it says chameleon after the root process change it to Sprint and ro.cdma.default_numeric from 310000 to 310120 and restart ur phone.

Galaxy S7 AT&T keeps crashing

I got a SM-G935A (rooted) that seems to be crashing about every 4 days and gets stuck in a boot loop
and only a factory reset will recover it. Can anyone advise what I can do? I wanted to flash a different
ROM since the AT&T is full of bloatware and I have no 5.8Ghz Wifi either.

Let me guess, when booting you get a short vibrate then two fast ones?

Yes when it boots and gets to the AT&T logo it vibrates and will not continue

Ive had the same problem...... was told have to watch what system apps you freeze with titanium backup, and if att sends new security patch and detects phone is "custom" knox will lock it up......... im not sure if those are the reasons but after alot of digging around thats what i found.

Thanks for your input. I wanted to replace the AT&T ROM with something better and was looking for suggestions. The
other problem is that AT&T has disabled the 5.8Ghz Wifi. What would be the best alternative to replace the AT&T
Bloatware ROM with? Is the T Mobile ROM a better alternative?

Flash the U Software. I have used the AT&T, TMobile and the U firmware. The U firmware is by far the smoothest. You loose VOLTE, but the rest of the phone runs so much better its worth it.

Thank you for your suggestion. What is the "U" software and where do I find it? Can I get updates with this software? Will this eliminate the crashes and is it faster since the AT&T firmware is very sluggish and slow?

Does the "U" firmware work with the Galaxy S7 Edge? and how easy is the install process? any risk of bricking the phone?

Unlocked Factory Image for Carrier locked STV100-1

Hello all,
Attached are modified factory roms that will flash an at&t or t-mobile phone to an unlocked phone. This means no more bloatware and in my case much better handoff between the lte bands.
These images reuse the carrier bootloader (I'm working on it) but everything else from the radio to the rom is from the unlocked priv.
Version: AAJ919
AT&T -> unlocked hybrid: https://www.androidfilehost.com/?fid=673368273298947044
T-Mobile -> unlocked hybrid: https://www.androidfilehost.com/?fid=457095661767153589
Directions: Unzip files. Hold power and volume down until phone reboots to fastboot. Launch flashall.bat. Follow instructions. This WILL delete your data so have a backup or don't I'm your boss. Wait. Done.
As usual I am not responsible for you bricking your phone. That being said even if the wrong file is flashed the phone gets stuck at the fastboot screen where you can flash the right file.
-Happy Modding

Can you provide more detailed instructions please

Im serious thats all there is to it.
What parts are you having problems with?

Didn't work for me, unfortunately. Phone promptly asked for SIM Pin.

This does not unlock your phone, this is an unlocked rom with no carrier bloatware.
You must already have an unlocked phone. If your phone is paid off call your carrier and ask for the pin.

I tried it and it worked. However, once it boots it will install a software update which takes you back to the bloated VZW version. Perhaps there's a way to block that update?

Totally possible. If we had root just modify the host file and set the verizon server update ip to localhost. You should be able to install DNS66 and do something similar. This will take digging on your end to figure out what the update IP is though.

I have an ATT Priv, so if I flash this I'll get next time OTA from BlackBerry instead of ATT? Saw the one above with the Verizon update and went back to bloated version.

Reporting back in to verify that it worked flawlessly on both at&t and t-mobile variants I have. Now if only we could get root lol
Thank you so much for your effort

I have an ATT branded Priv which got unlocked from ATT directly and has successfully installed this ROM. It works perfectly without any ATT bloatwares, but this built is old and when I check for system update it shows my system is up to date. However the most recent built for unlocked factory image is AAL202 according to the blackberry official reload software website.
So does this ROM OTA updates via ATT server or directly from Blackberry server?

Does root leave some obnoxious message?

I'd really like to root my Galaxy S8+ (AT&T) but I'm worried that it will leave some warning message every time the phone boots like it did with my Motorola G or Huawei 6x. I know from past experience that Samsung Android products may show a small fine print on boot and can be reset at anytime back to factory (the Huawei, in contrast, cannot).
Is that the case with the S8?

Anyone? Comon guys!

Hi if you have the US phone, at boot there is a custom firmware screen or something. It will go away after a few restarts if you go back to factory though.

It's not perm. This is a result from the combination file boot IMG. Its only on for like 3 or 4 sec. And if you ever flash back stock since we don't have unlockable bootloader it's not perma

Cool, thank for the reply! It doesn't seem too bad and, if your warranty is already expired, you have nothing to lose.
Is there an original rom that's debloated for this?

Hi
Would someone help a newbie please.
I am using an S7 Edge with a cracked screen. Given the price of proper replacement screen it doesn't seem worthwhile.
It seems better value to buy an S8+, but which model number? There are apparently 12 different versions! Could anybody please tell me which model of Samsung Galaxy S8 Plus would be best for the UK?
Cheers

Rooting the US does not lose the warranty. Root does not trip the Knox. Only unlocking the boot loader which we can't do
