This is actually the first ROM I've ever flashed on this device. The SIM lock wasn't caused by the ROM. It was actually caused by an automatic update that happened after the phone was rooted which patched something in the network data that caused it to SIM lock. I believe in order to fix it, I need to download something that removes the patch or something that changes the firmwares network information to re allow 3rd party SIM use.

I was told it be would be best to go to a Best Buy and have the Samsung people reflash my phone. Since I don't have a computer, they would be using what's called Samsung Switch to flash back to original OS.
[Galaxy S6 Android Development] Obeythenerds:
Do you have backup before you rooted? If not then I would say you could try to find the stock rom for your phone and flash that or to try the best buy method that you were trying about.
[Galaxy S6 Android Development] ShawnInRP:
I'm so sorry to hear this. It is obviously a bummer for us supporters. But to say it sucks for you personally is an understatement. I've been there a few times. Different situation but same idea. Worked for months on an insanely complex data extract for one of the hospitals I support. Another programmer decided to make a minor change, but first wiped out EVERYTHING I coded. Almost lost my job due to flipping out that day. Between that and my hard driving crashing another time, I learned one word the hard way and live by it now...redundancy. I constantly make multiple back ups of everything now. My case is different since other programmers (all virtual) can touch anything. But I'm constantly afraid of losing anything I work on.

Obviously not bashing you saying you should've done this or that. Just sharing my horror story to let you know I feel your pain! It's devastating.

Thinking out loud...I've seen companies that can recover nearly anything from failed drives. If I remember right, their prices are between $100- $200 to do the restore. While we shouldn't expect you to try it to appease us, I'm sure getting most if not all of your blood sweat and tears back would be huge for you. Maybe we can all chip in a little to help and show our appreciation for the insane amount of time and effort you sacrificed to build the greatest rom hands down. I will try to find those companies I came across before when my drive failed in case that helps.

Regardless of the outcome, THANK YOU [MENTION=364033]stangdriver44[/MENTION] for all you've done. You've given me a reason to ignore every upgrade opportunity. I can't imagine not having all of these amazing tweaks available. I know I'm not the only one. As I've said since I hit the jackpot finding your thread and rom back at v3, you are the MAN! No bad drive can change that!
[Galaxy S6 Android Development] DarkXShadowX21:
I would rather not lose root but if I have to sacrifice root at the end of it all, so be it.

Isn't there something that exists that fixes the SIM lock issue after an auto update patch messes it up? Surely I'm not the only one person this has happened to.
[Galaxy S6 Android Development] slickrick54:
Try flashfire from the play store
[Galaxy S6 Android Development] ShawnInRP:
I'm sorry, just thought of something. My laptop's hard drive had a catastrophic failure about 2 years ago. Laptop became a paperweight, wouldn't do anything. I pulled it out and hooked it up to another computer via USB using a cheap adapter. To my amazement, I was able to access EVERYTHING. Didn't lose a thing! I don't know if you tried it yet. But for maybe $10 tops I witnessed a miracle! Could be worth the minor investment to at least see if it works. Worst case, return the adapter and get the money back. Just trying to help somehow
[Galaxy S6 Android Development] DarkXShadowX21:
What am I suppose to do with flashfire?
[Galaxy S6 Android Development] slickrick54:
Supposed to be able yo flash full firmware packages with it. So no need for bestbuy
[Galaxy S6 Android Development] DarkXShadowX21:
Where would I get the full firmware package for latest version of Android on this Samsung S6 G920T 6.0.1? Is that a free download? Will I lose root if I flash back to their firmware?
[Galaxy S6 Android Development] ShawnInRP:
[MENTION=364033]stangdriver44[/MENTION] I just PM'd you
[Galaxy S6 Android Development] Obeythenerds:
If it was caused by the root. I would just Unroot and see if that fixes it. You can always reroot.
[Galaxy S6 Android Development] DarkXShadowX21:
I can't reroot. I don't have a computer anymore. Mine ironically crashed too and I am having problems getting it to boot back up to a running state.
[Galaxy S6 Android Development] Obeythenerds:
You can just flash cf root
[Galaxy S6 Android Development] DarkXShadowX21:
I'm not sure what you mean by CF root. My apoligies, this is the first ROM I've flashed in almost 10 years. It took almost 3 days to get it right with no access to this phone or a computer. I moved from the iOS jailbreaking scene to the Android rooting scene and a lot of this information is pretty new to me.
[Galaxy S6 Android Development] Obeythenerds:
I see now. What did you use to root your phone?
[Galaxy S6 Android Development] slickrick54:
Sammobile or even on here just search and you will prosper. You will lose root but you can use cf auto root to root again and then flash a custom recovery
[Galaxy S6 Android Development] DarkXShadowX21:
I had a computer but ironically enough as it seems to be the issue of a few people in this thread, mine has also crashed to the point of no return. I used Odin to initially root this phone. I've never had success with the auto root attempts as well speaking of which.

I'm currently trying to download the very top firmware. Is this correct? It keeps on failing to download for me.

https://samsung-firmware.org/model/SM-G920T/

Would you by chance know exactly where I can find the latest firmware here on xda that is shown on that website?
[Galaxy S6 Android Development] The Sickness:
Root is achieved on the kernel side now. Use Flash fire to get you back to stock.
[Galaxy S6 Android Development] The Sickness:
https://www.sammobile.com/firmwares/download/122244/G920TUVS5EQA2_G920TTMB5EQA2_TMB/
[Galaxy S6 Android Development] DarkXShadowX21:
Thanks! So, I'd like to say thank you to you personally for creating the kernal that you did. I'm currently using the Twisted Kernal V8 although, I have absolutely no idea what it is but I'm going to thank you for it anyways since I am using it! ?

Secondly, I go to sammobile.com and download the latest firmware, use TWRP and flash the .zip? If I do that, I will lose root access correct?

If I do lose root access, which piece of software for mobile do I use specifically to reroot this device I'm on? ( Samsung Galaxy S6 SM-G920T )

I've tried Kingo root on other devices and this one and it has never worked for me. Not sure what the best method of rooting is without a computer these days. Any advice on this would be much appreciated.

Lastly, is there any other way that I could fix the patched update that happened with this device in an alternative method other than going to back to stock and having to reroot? Is there any kind of F/W package, OS zip, Kernal? Exploit? Available to reopen that door that the patch closed?
[Galaxy S6 Android Development] slickrick54:
Have you tried to put a tmobile sim in there for ****s and grins to make sure its not a hardware failure. We personally never heard of such update. From what i always thought once you get sim unlocked its unlocked for good even if you odin back to stock. I'm no dev but maybe one will chime back in for you
[Galaxy S6 Android Development] The Sickness:
Your get the firmware from the link I sent. You download it and use Flash Fire to flash.

Once you have done that successfully come back here.
[Galaxy S6 Android Development] DarkXShadowX21:
I did put a t-mobile sim in here as a matter of fact and it works perfectly. I am currently on the carrier Cricket Wireless. After I rooted, I was still able to use my device with the 3rd party carrier. A few weeks goes by and I let my phone sit on a charger overnight in a powered off state. When I booted it back up, I ended up walking away from it to go make breakfast or somethihg. When I came back, it had an error message saying "Invalid SIM card" please use the Unlock Device app to unlock your device, etc.....I've already used this app originally and have permanently unlocked my device and called it in to T-Mobile to verify the state of the unlock in which they have confirmed it is 100% unlocked legitimately.

So, overall, I believe there was an update without my knowledge and it has patched some kind of network information to block the use of 3rd party SIM cards. I am hoping to find something that unlocks this. Perhaps go back 1 or 2 firmware updates and reinstall that instead of the latest one? I'm not sure at this point and hopefully can come across an alternative solution besides the most common answer of going back to stock and redoing the entire process all over again.

---------- Post added at 06:57 PM ---------- Previous post was at 06:56 PM ----------

Will do this if there is absolutely no other options available to me.
[Galaxy S6 Android Development] The Sickness:
Only option you have is to use a pc to flash the firmware with Odin.
[Galaxy S6 Android Development] DarkXShadowX21:
Didn't you just suggest flashfire and downloading the firmware though? I'm confused now. Which is it? Only available option is pc or can I go through the process via mobile with flashfire and reflashing back to stock with rerooting as a possibility?
[Galaxy S6 Android Development] The Sickness:
If you have no pc, flash fire is the only option. Does that help now lol
[Galaxy S6 Android Development] DarkXShadowX21:
Yes, thank you for clarifying. Lmao!
[Galaxy S6 Android Development] The Sickness:
:good::good:
[Galaxy S6 Android Development] slickrick54:
To be honest when i stuck a 3rd carrier into my phone it said the same think invalid sim. If i were you i would flashfdire stock then call tmobile and ***** them out and tell them to redo there unlock again
[Galaxy S6 Android Development] DarkXShadowX21:
I already verified the unlock though with them. Do they have the option of redoing the unlock after its already been unlocked permanently?
[Galaxy S6 Android Development] slickrick54:
For real homie lol! They have the option to permanently shut down your phone or sim service i should say if its lost or stolen now. I'm pretty sure they can send an unlock code again
[Galaxy S6 Android Development] DarkXShadowX21:
I don't have anywhere to enter an unlock code though. Is there a way to bring that option up so I can just call them and ask what the unlock code is again that way I don't have to redo everything?
[Galaxy S6 Android Development] same-xx:
This may be stupid but isn't there normal service menu in s6? There u enter sim lock code and band mode + stuff?

Heres the device unlock app. You can try and push it to system priv app and correct permissions and reboot. Then you will have the app and you can then try and call tmobile. Other than that bud I'm out of solutions for my knowledge

---------- Post added at 01:45 PM ---------- Previous post was at 01:41 PM ----------

Yup there is codes like that but i have no clue on what the numbers are lol. Something like *#6626# or some shizz like that. As a matter of fact google service menu codes for s6
[Galaxy S6 Android Development] same-xx:
Found this for service menu: https://xdaforums.com/galaxy-s6/help/service-mode-band-selection-sm-g920f-t3111463

Edit: U can get there with samsung phone info from play store.
[Galaxy S6 Android Development] DarkXShadowX21:
I tried this, it said "Not registered on network". All the codes I try so this error message as a matter of fact and I just tried a bunch of them back to back.

Good news everyone!

OZOP is back from the dead, Resurrected!

With some recent extremely generous donations from [MENTION=3538858]slickrick54[/MENTION] and [MENTION=2682364]bigtom624[/MENTION] I was able to purchase the equipment needed to extract the data (All my OZOP update files) from my old hard drive saving me countless hours!

Not to take anything away from those two above, but I have to make this one big because [MENTION=5047348]Avn1007[/MENTION] saved the project by sending me a fresh laptop from which OZOP Resurrected can begin breathing life again!

So with the help of this community and the generous donations brought forth from the awesome users here, OZOP is back!

Now everyone please bare with me because it's going to take me a few days just to get things set back up and ready to get back to the v7 build, but I am on it and v7 will hopefully be ready soon after!

Thank you all for the support and patience!

Also please be sure to thank and show appreciation to these guys for helping keep OZOP alive! Thanks guys!!!
[Galaxy S6 Android Development] bigtom624:

[Galaxy S6 Android Development] DarkXShadowX21:
Thank you for adding it back. I have the .apk file how. 2oyld toy much do explaining a little more in depth where it goes and which permissions to set please? Thanks!
[Galaxy S6 Android Development] slickrick54:
Use root explorer or any other root file explorer app. Then just copy and paste that entire folder into system priv-app and then change the permissions to rw-r-r and then reboot. Then you should see it in your app drawer once booted back up. Then call tmobile and see if they can send you the unlock code again
[Galaxy S6 Android Development] DarkXShadowX21:
Yoy mean the folder that is created after I install the .apk? I haven't installed it yet. Just have it downloaded.
[Galaxy S6 Android Development] slickrick54:
It's a system app bud can't just be installed. Has to be pushed into system priv-app like i just explained to you. Then correct tje permissions and reboot. Heres a ss of what it should look like
[Galaxy S6 Android Development] DarkXShadowX21:
It says this when you open the application though.
[Galaxy S6 Android Development] DarkXShadowX21:
Like this right?

It still says device is incompatible.
[Galaxy S6 Android Development] slickrick54:
Wtf how is that possible lol hers my screen shots of it
[Galaxy S6 Android Development] slickrick54:
Well then change the buildprop back to SM-G920T then and reboot
[Galaxy S6 Android Development] DarkXShadowX21:
See....
[Galaxy S6 Android Development] bx10r:
Have u tried another rom with just ozop oc?
[Galaxy S6 Android Development] slickrick54:
Go back into aroma and choose your model specific and it will change it back to SM-G920T for you or just go into system build prop and open it with a text editor (root explorer has one built in) then change it back to SM-G920T then reboot
[Galaxy S6 Android Development] DarkXShadowX21:
How do I change the buildprop without messing up my phone? It seems like everytime I go into OZOP from TWRP, I seem to be resetting everything and have to do the phone over from scratch. I've reset this phone at least once a day for the past week trying to understand it. Lol

---------- Post added at 04:03 AM ---------- Previous post was at 04:01 AM ----------

OZOP OC? This is the first ROM I've flashed in almost 10 years. I haven't found anything else for the SM-G920T that was a good ROM and Aroma seemed by far the most advanced and unique out of all the other ones I've read about.
[Galaxy S6 Android Development] bx10r:
Im on a flat running just ozop oc with sickenss rom. My about says g925t....hmm go figure...lol. just an fyi.....
[Galaxy S6 Android Development] DarkXShadowX21:
I switched the model number in Root Explorer. I still get this message everytime I boot up and the Device Unlock still says it's not compatible with my device.
[Galaxy S6 Android Development] slickrick54:
Bro you got hustled you need to call tmobile really fast and also get a hold of the guy who sold you the phone and slap the **** out of him with it and get yo money back. It says network lock so i bet you he sold you a phone that had a payment plan on it still and he just stopped payong on it hence why its saying network locked. Normally i always thought it said invalid sim but i could be wrong and dont have a 3rd party sim to try again
[Galaxy S6 Android Development] DarkXShadowX21:
Nah, that didn't happen because T-Mobile told me it was permanently unlocked. Technically if the phone was on a payment plan and the original owner didn't flip the bill, the imei would be locked onto that account and not allowed to be unlocked until the account was paid off. I used to work for Sprint and had to deal with **** like this before.
[Galaxy S6 Android Development] slickrick54:
Ok my bad then just seen network lock and was like wtf. Can you try the tmobile sim in there one more time and reboot and run the app again since the build prop is changed back to your device specific and if it works then just put your sim back in and try and see if it holds. Im just fishing for answers now bud sorry
[Galaxy S6 Android Development] DarkXShadowX21:
You're good, no worries. Unfortunatly, I don't have a T-Mobile SIM. I never had T-Mobile as a carrier, I just have the phone from someone who did. The only SIM I have is my 3rd party Cricket Wireless SIM. I have tried a T-Mobile SIM and it works perfectly fine in this phone.
[Galaxy S6 Android Development] slickrick54:
Damn was just wondering if maybe just maybe since that build prop change didn't match up to a flat when you flashed Ozop if that would have made the network think it was a different phone himdering it from being unlocked. I dont know but sure wish you had a sim to try it on
[Galaxy S6 Android Development] DarkXShadowX21:
Thank you Stang for jumping into this with me and everyone else who has been helping me with this issue thus far.

You are correct in stating that before I ever rooted this device, I was 100% unlocked and my 3rd party SIM worked just fine. Even after I rooted my phone, it was working for a little bit and an auto update is what I believe happened when I stepped away from my device while it was plugged in which caused it to patch a security gate to not allow 3rd party SIMs on root access.

I've already changed the devices model back to the SM-G920T manually through root explorer but I will take a look at your tweak list and double check there as well.

[EdIT]

How do I upload the stock build.prop and do you want me to upload it to you right here in this thread or in a pm?
[Galaxy S6 Android Development] stangdriver44:
So your device is a 920T and your carrier is?

You own your device outright, you owe Tmo $0.00?

Have you call customer care?

If you do, THIS IS IMPORTANT! UNROOT YOUR PHONE BEFORE CALLING THEM! Just to be safe! I've heard of people getting burned as they will use the "your device is rooted" excuse to get out of anything!

Either way I think we should try the unroot method, same way as getting snapchat to work. Google it if you don't know. I'm looking into other things
[Galaxy S6 Android Development] DarkXShadowX21:
So your device is a 920T and your carrier is?

Cricket Wireless

You own your device outright, you owe Tmo $0.00?

Correct

Have you call customer care?

I have. Twice actually. Not really much help to be honest.

I guess I will Google how to unroot without a computer. Thanks.

By the way, would this service menu do me any good?
[Galaxy S6 Android Development] stangdriver44:
[MENTION=2444972]DarkXShadowX21[/MENTION], I noticed in your screenshots that you're connected to WiFi.

Edit: looks like the Wifi connection only refers to temporary unlock, sorry...

I might suggest trying the Stock EPK5 rom zip from the Tmo development thread, I built that, by which I mean I only extracted from the official tar file, deodexed and made zip flashable in recovery from your phone.

Plus if you are running the EPK5 base and you're interested I could use use as a tester for the OZOP v7 update?

Does your data or text service work?

The very brief scan I did about this issue pointed to the app not working when connected to Wifi.

Check this post and see if all checks out for you

What was the original build number you were running when you had the sum unlocked?

To unroot is simple, just open supersu app from app drawer and scroll sown in the settings tab about 3/4 the way and you will see an option for "full unroot" click that follow the prompt and your device will unroot. To reroot again you can select that option in the mod/tweaks section of Aroma or select the kernel of your choice in Aroma as well or go to the chainfire supersu thread for the latest version.
