[Q] S4 Network unlocking issues - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I have been trying to unlock my AT&T S4 and after trying several methods am having no luck. I tried the *#0011# and am unable to make any changes due to an update that I can't seem to get rid of. I purchased an unlock code from a reputable unlock site, (bought one from them previously for girlfriends AT&T S4 and it worked perfectly) the code for my phone won't work. They offered several troubleshooting steps, from various *# number combinations to factory resetting my phone. I did a hard wipe (holding down vol up, menu and power button) and that still didn't work. I am thinking maybe I could try flashing an earlier version of android? Does anyone have any suggestions that I could try? Any help would be greatly appreciated. Thank You!

Update to Unlock issue
I have finally resolved my problem, after reading through many of your helpful posts on here, I decided to give Region lock away a shot. I tried to purchase from play but it kept declining it saying it was high risk and to try back in 24 hours, so I got it from here, rooted my phone, installed the lock away and sure enough, it unlocked the phone. I am going to leave this post up, even though no one replied yet, in case someone else has my same problem, maybe this can help.

Network unlock message on start

Hi all,
I have been searching and trying to mend this before posting here but have come to a dead end so need some more advice if possible.
My sister has the S2 and one day it just stopped receiving signal, she restarted the phone and it was asking for the network unlock pin! She got sent some new sims to try and none worked. She had googled around and see that people had success with rooting the device.
I tried this and got the unlock code from chainfire app and tried that but it didn't work. I thought I had unrooted it successfully but it appears not because when she sent it off it came back as warranty was void.
So far I have tried chainfire app to get the unlock, tried the other S2 unlock along with the GII_Repair app from market. None seemed to have worked and I was getting prompts. I flashed clockwork and then CyanogenMod nightly hoping that the factory reset and the modem driver change or something might get it working, but nothing has worked.
Does anyone else have any ideas of any possible next steps I can try?
Thank you
Rich

I've also ran into this issue. As you've tried, I've also tried reflashing the factory firmware via Odin, and rerooting it. Sometimes I could get signal, and the baseband is fine and sometimes the baseband is unknown. Coming back from the screen lock, the phone will have no signal.
I've tried everything from every forum on the web and still couldn't fine a solution. I've done a different SIM card as well and things still don't work. Also flashed multiple modems and still, connections just wasn't stable.
Afterwards, I gave up and exchanged it for a new one. Hopefully you can restore factory firmware and exchange the unit as I don't think anyone has solved this issue yet. Good luck and hopefully you find a way to fix this issue.
If you want to restore the factory firmware, you'll have to do a little searching on the web here, and look for factory firmware and flash it using Odin from either your computer or using the odin app.

[Q] Galaxy S5 locked on Reactivation Lock?

Hello I bought my verizon galaxy s5 yesterday on craigslist knowing verizon phones now come factory unlocked and intended to use it with my T-mobile sim. When I tested the phone everything worked fine but later on when I got home I decided to factory reset it to clean it up and now I am stuck with a "reactivation locked" window asking me for the owners samsung id, I then tried contacting the seller and now he wont respond so I am stuck with it. I have now made research and know that its a security new method on verizon phones. Is there a way to fix/disable this? any input will be greatly appreciated, thanks.
verizon phones now come factory unlocked??
This is news to me.
Kies or Odin might allow you to install a new image.

This has been the case with 4G phones. It is sim unlocked, as in you can use other carrier's sim cards, not with an unlocked bootloader in case that is what you were thinking.

You will have to get it from the seller.
It likely wasn't done maliciously nor may they remember even setting it.
IIRC when setting up the phone it is an option that you can enable. Chances are it may be a password they use for many things and my not want to divulge it?
Unfortunately you will have to get ahold of them as only they know the password.
The only other thing I can think of is flashing the ODIN tar. Not sure that this will reset it anyways as when you enable this option there is a message saying that Reactivation lock must be disabled before sending your phone in for service.
9/10 guy probly screwed u for a claim because that feature would have to been activated it wont activate on a reset as it would have asked for password prior to reset and the fact that its asking for the Samsung id is evidence to the fact

This is the second thread you've done this in. Stop finding year old dead threads and posting a link to the solution that was found a year ago. If you want to get your post count up, try posting something useful (like me) in a thread you can contribute to:good:

I found a way to access the devices of my sm-g900v with the build OE1 with this problem. So the bug i found is not complete but, i know that someone could do something with this info. All you need is blue-tooth headset mines are the lg HBS750. First you have to call 911. turn the bluettooth on and Quickly disconnect the call... you should be on the searching for devices.. At this point you connect you headsets and connect to wifi.. and press the speak/call button on the headset. S-voice should pop-up and ask you to connect to wifi (if you didnt follow my directions) if you did, you should be able to open settings are any stock app... i tired to disable from the settings but, it keep re-checking itself. Maybe someone could find out use this access to disable the reactivation lock.
have you find any solution to the reactivation lock?

if you find anything that WORKS, plz can you post it here, i have the same problem, I bought a G900V, later upgrade to PD1 android 6.0.1 and find the surprise
I've got some phones with a reactivation lock as well. I'll look into above. Any chance you could bring up adb? If so I can give you the adb input commands to force a hard reset via a bug, it may work and bypass reactivation lock as it is a full wipe, but no promises. Otherwise I have a theory for disabling it via a script that can be pushed via adb and executed. I need to see if I have time, cause it needs to be done
Thanks for getting me that far!!!
ive gotten close

I have an s5 on bok3 firmware right now with a samsung reactivation lock lockout without root or unlocked bootloader and no custom recovery
i first went back to bok3 firmware then used the otg usb/cable bug to access the file manager i've also gotten into play store settings phone and couple other things but also i force closed a bunch of apps and then backed into the setup wizard and got phone activating as if it was a new device but alas it failed as i had disabled and/or forced close activation agent. I haven't been able to recreate since. ps you can access lock screen by going to android device manager on the web and using the lock feature to change the lockscreen password. I also discovered samsung account is the issue app for reactivation lock as when i force closed and disabled it setting menu crashes instead of does nothing when you try to do a factory reset in setting or add a samsung account to your device.
perhaps we can install a custom version of the s5 samsung account app to our device i dont have the skills to change it but you might. Just a thought
Reactivtion lock is off!!!!!!!!!!
I booted NCG on PB1 Bootloader
is a new thread on s5 verizon general on xda
im testing it to see if reactivation lock can be circumvented this way will tell you either way as soon as i can
IT IS CONFIRMED WORKING AND REACTIVATION LOCK IS OFF

Unable to update MX4 Pro and several other issues

Hey guys,
I've bought my MX4 Pro almost a year ago, but decided only now to ask for your help. Hope you'll be able to guide me to fixing the several problems i have.
First of all, phone came with Flyme 4.5.7I and right from the start there were some features not working. Most important, the fingerprint screen unlock isnt working. After capturing my fingerprint, when i try to enable it to unlock screen it just takes me back to the home screen.
Another issue is getting sometimes (it happens randomly) a no sim error. Sometimes restarting is enough, sometimes i need to take out the sim card and insert it back.
Ever since i've tried to update firmware, hoping it would solve my problems. Nothing has worked.
Dowloaded the update.zip (no matter which version) and placed it in root directory. When i try to open it with the document app i get two options, view and extract. Can't update. Also starting the phone using volume+ and power button (update screen) has always produced the same results: Firmware corrupt. Tried doing it with clearing data, without that, no difference. Tried with a .bin file, same thing.
As far as i know the bootloader is locked, and i remember checking if the device is properly rooted and IT IS NOT.
So, the more android savvy people here can help? I'm lost and i really enjoyed the phone so far, but i dont really know what to do from now on. Is it a faulty device? (This would be the worse, since the phone was bought from China).
I can provide any additional details if needed.
Thanks in advance
P.S. I remember trying every tutorial/solution out there, nothing has seemed to work. I also may be dumb, not sure.

Galaxy On5 sm-s550t stuck at frp

So I've searched around the past few hours and can't seem to find a solution to my issue. I have a friend that is currently down on his luck and staying at a homeless shelter, he bought this phone because phones are pretty much a necessity nowadays, samsung galaxy on5, trouble is that the phone was locked when he turned it on so he was stuck with a paperweight, it's been a long time since I tinkered with phones but I figured I could help him out by booting into recovery and doing a factory reset. I had no idea about samsung factory reset protection and now were back to paperweight mode. I downloaded jodin3 and heimdall, but it never shows as connected. Can I root the phone while in recovery or load the factory rom so I can get the phone working again? Thanks for any help.
No, the only options are either ordering a remote unlocking service or find a guide on YouTube. The YouTube way will involve some patience and trial and error. Many guides don't specify what update on the phone they are working on and/or will state that their particular method works for EVERY phone. The stock recovery will tell you what update that it is on by the build number. This might help pinpoint which method to work.
FRP = Google Factory Reset Protection
Samsung Reactivation Lock is a different beast.
Which one does the phone have?

Sprint GS7 - No WIFI and "CUSTOM" after last OTA update. KNOX 0x0.

Ok, so this is my wife's phone. After the last OTA update to QE1, she noticed that the WIFI would not turn on. I kinda ignored her for a couple of weeks until she really made a fuss of it. When I finally got around to it I also noticed that "CUSTOM" was present in the phone information area as well as upon bootup. I've searched XDA as well as other sites and tried everything I could think of but nothing has helped. I cannot mess with any WIFI settings because it will not turn on at all so I can't even access the menu. Neither Sprint nor Samsung will touch the phone because they claim I rooted it. I didn't. I have factory reset it numerous times with no luck. I have ODIN'd the software for a full reset and used all older software versions even. Following Sprint's own software updates, no luck. I have used the Samsung SmartSwitch program on the computer to also do a full reset to factory multiple times with no luck. The Samsung rep at the local Best Buy even tried it. The only thing that a full reset helps with is getting rid of the "CUSTOM" notification until you reboot the phone. It doesn't fix WIFI.
Has anyone had experience with this problem? I am getting ready to root it, but I'm not sure if that will even help. Additionally, the phone currently does not have Sprint service, I had to activate her old phone... So, I don't have access to the internet with the phone unless I reactivate it on an account... I looked at a root option, but it requires wifi...
I'm open to suggestions. Please help..
Ok, so no one has any input on how to fix my problem. Is it not possible with the locked bootloader?

After running odin with stock firmware, go into recovery and hard reset the device again . As far as Hard Bricking on Purpose, that would be fraud, something not allowed to be discussed here. Mods please lock this thread.
Thanks for the reply. Sorry about breaking the forum rules, I went ahead and edited my original posting. I've already tried odin with stock firmware and hard resetting the device numerous times with no luck... I'd like to be able to dig deeper into the phone but I'm guessing that won't be possible with the locked boot loader?
