Long time reader and tinkerer, but first time poster... This is a two-part thread:
I picked up a cheap used Samsung Galaxy S4 phone, hoping to unlock it and use it. When I received it, it was a SM-S975L, which I can barely find any information on:
Model number: SM-S975L
Baseband version: S975LUDUANB1
Kernel version: 3.4.0-2485535 [email protected] #1 Tue Feb 4 17:57:30 KST 2014
Build number: JSS15J.S975LUDUANB1
SE for Android status: SEPF_SM-S975L_4.3_0017
Product code: SM-S975LZKATFN
Current firmware on my phone: www DOT sammobile DOT com/firmwares/3/?download=28755
Part 1: Custom ROM.
I want to use a Google Edition ROM instead of the bloatware that comes on carrier devices. I'm unable to find a recovery for the SM-S975L, much less a custom ROM though. Is anyone out there that would entertain the idea?
PARt 2: SIM Unlock.
With my sim in the phone, a SIM Unlock code screen doesn't pop up on its own. I typed #7465625*638*# into the dialer and it did finally appear. I was able to successfully sim-unlock it once. But after a phone reboot, the phone was re-locked and the sim unlock code I previously used no longer works. Has anyone ever had this happen? I would like a permanent solution to sim-unlock.
Thanks!
Hi jeredh....I have the same questions as I just ordered this model. Have you solved or tried out anything on your 2 questions?
-JC
I wound up selling it and changing to an S5 Active. No luck at all finding anyone or anything for that phone.
Another purchaser of the S975L here. Thought $249 was a great deal for this phone, but got home and realized that it's actually a really locked down phone. No permanent way to unlock it (unless you own it for a year in which case Tracfone will unlock it), bootloader is locked, no one has developed a custom ROM for it, and the complete tethering framework has been removed (so not even rooted tethering apps will work). It's a good bet that Straight Talk will never update the firmware on it either. That last one is a huge bummer because Android 4.3 is *okay* for now, but KitKat has been out for a while, and Lollipop will be ported very soon. It's fantastic hardware gimped by awful software. A shame really. I'll probably hang on to this phone for a little while since it's a definite improvement over my old iPhone 4S, but I'd like to move to something I have a little more control over.
The only solace I have is that it's easily rootable using TowelRoot.

If you have the unlock code and root, then follow this.
1. install samsung phone info tools from the market. Run it and allow super user access on it.
2. Press menu and go to secret codes, and let it load.
3. Once generated scroll until you find 7465625*638* you should see two. One that says unlock and other says lock.
4. Select the one that says lock. Press it and select "launch 0" on MCC/MNC field enter your carriers MCC/MNC code.(google it if you dnt know it) on the Control Key enter unlock code. Press ok.
5. Select the 7465625*638* that has unlock on it, press launch 0, enter unlock code. Press ok.
6. Hit thanks, device should be unlock with no neet to reboot.
**You need to do this everytime you turn off, turn on, or restart the phone.
Question: Wondering how you got the unlock code?
WAITING
Hello,
I will follow the question, how did you manage to get a code?
I really want to at least unlock my phone to use it,
I know aromerblz is going to make a guide, I have to wait and try it, I am really not having idea what to do to make it work
NO UNLOCK CODE for Permanent Unlock!
.
An UNLOCK CODE for this phone only TEMPORARILY unlocks it.. everytime you power off and phone on OR restart it then it will ask for the code again.. This phone is very well programmed and cannot be permanently unlocked. This is a Straighttalk phone.. its not meant for other carriers.. if you bought this thinking you were getting a deal you were probably wrong.
network unlock
if I purchase a code from a third party and I enter it everytime I reboot does it work on the other network everytime ?
Sm-s975l unlock info
This model is permanatly unlockable through Straighttalk after a 1yr of active service ( If you are late adding time & if your phone deactivates, you must begin the 1yr requirement from the begining )
But good News there are 2 compatible Models of the S4 you can use to Customize your SM-S975L.
Most ROMS are compatible. You will need to have your Device "ROOTED" with Custom Recover Software.
Just my advice use TWRP as Cmod tends to Brick Devices " Just from Personal Experience "
The M919 - Forums General Location
http://forum.xda-developers.com/galaxy-s4-tmobile
The I9505 - Forums General Location
http://forum.xda-developers.com/galaxy-s4
The Most Compatible ROM for the SM-S975L was Created by a Very Talented Developer "The Sickness"
Download V11 4.4.2 & the Mod File. Now Boot into Recovery Flash the Rom 1st following the instructions provided on the download page allow the 1st boot up to complete. Name your phone & all that other fun setup info Stuff. Then reboot into Recovery, & do a advance wipe on Cache & Delvic lol & you can now flash the MOD pack, I recommend choosing the Ktweaker OC Kernel by Ktoonz you can pplay around with the other Mods but be warned the S5 Mods Tend to cause device errors with settings/menu/&keyboard. This rom http://forum.xda-developers.com/showthread.php?t=2683507
DONT LET ANYONE TELL YOU THE INSANE HYBRID 4.4.4 ROM UPGRADE IS BETTER ITS NOT THAT ROM IS BLOATED AND SLOW AS DIRT
There aren many ROMs to choose from icecream sanwich to marshmellow But none as good as "Sickness's" INSANE KITKAT Versions Vary but the Only Rom that comes even Close is SPIKE LABS 4.4.4 GAMING ROM with kernel juicer but its still a bit jittery at times when the GPU is pushed & games are Drawing Heavily On Your Device..
As far as the Baseband is concerned you can remove it and attempt to upgrade it Via ABD pull & push. " Aquire ABD & fastboot files & launch CMD W/ADMIN RIGHTS" & it is possible to use ABD CMDs to remove & apply another Basebamd but this could super brick your Device if it is not unlocked.
Hope this Helps Lot Peeps

I was in the same boat, had an unlock code, it worked one time then after a reboot it would not accept the unlock code. I happened upon this post (while I was searching for the stock ROM to reload on it), and decided "what the hell let me try these steps"....it works. I don't mind going through these steps on each reboot. Infact I made it a bit easier, I installed Shortcut Master (Lite) and made two short cuts, one for the lock and one for the unlock.
Thank you for posting these steps.

Though I do have a question. Are there any ROMs out there that are based on Android 5.x that will work with this? I tried flashing Cyangenmod but the "secret" codes needed don't seem to work at all, infact Phone Info only shows like 12 or 13 codes.

Yes there is.. Any TW based ROM for the SGH-M919 or GT-I9505 works for this phone. CM, AICP or ASOP ROM's do not work as they lack the perso codes for unlock.

Clarification, they do work if you live in the USA as you will still use with TracFone service. But to uses on another carrier you need the unlock code and a TW based custom ROM. Where you got your code?

I got my code from imei-unlocker.com
Like I mentioned in my original reply, the code worked once then after a reboot it was locked and the code was not working. But with the steps that was posted, I am able to use my T-Mobile SIM and just go through them steps after each reboot.
Oh and the best part, the site actually refunded my money cause I was working with them as to why the code stopped working.

It's all good. Just need to find a TW based ROM now. Thanks
If you have links to any that you know to be decent, it would be much appreciated
Straight Talk SM-S975S unlock
This phone is unlockable by design. The only way Straight Talk gets around the" unlock law " is they offer you a credit towards another phone, my offer was $100. I have a friend that works for Samsung and he researched it at work, talked to the tech's and was
told Straight Talk ordered the phones this way to stop people from buying their cheap phones then switching companies.
Hello guys so I was just wondering if it's still possible to unlock the bootloader of the p8 lite since they remove the code generator ? I would like to root it but i cant unlock the bootloader , anyone have an idea on how to do it ?

You can use DC-unlocker but that costs 4$.
Or you may be able to use this method.
Also I saw on the p10 lite forums that someone found a website where Honor provides a limited amount of unlock codes for XDA members. But he is not sure if that is really legit. Anyway the thread is here.

Yeah Honor has started providing limited number of unlock codes to its users... But that's a catch, it's on First come First serve basis... And the main thing is only for Honor devices, Huawei codes won't be there
