Seem s TMO G5 is easy to be unlocked to use other GSM carrier.
Many unlock service website say they can unlock it by several steps.
Typically check if the H830 can be unlocked, by following these 3 steps:
1. Install T-Mobile APP from Play store.
2. Open the app and press Permanent unlock.
3. The following message should appear: Unlock Failed: This mobile device is not eligible for unlock. blablabla...
And if you get a different message you CANNOT unlock this device.
So question is coming.
Is anyone experienced in this thing? In which cases G5 will appear "Unlock Failed" message?
I guess if the phone's IMEI is clean but not use TMO network for enough long time or just even never activated on network then we can pay extra money to that kind of website to unlock the phone. If IMEI is in blacklist so the problem is not just like "this mobile device is not eligible" so simple .
Am I right?

I have an 1.3 rev Samsung Focus. It was an unlocked model I got from outside. I was in the US at the time of Mango update and updated my phone with Mango from AT&T. Now I have moved out of the US and want to unlock it. AT&T doesn't have the unlock code because I didnt purchase it from them. Any Ideas on what I can do? Will a custom ROM help me with Unlock? When I check lock status, it is SIM Lock is Disabled, only Network lock is enabled.
I'm not sure what you meant by "It was an unlocked model" in the context of "out of the US and want to unlock it". Was it unlocked or locked? Anyway:
Read the wiki, (carrier) locks are in NVRAM, no relation to flashing whatsoever, so any custom ROM won't SIM unlock your phone.
Have you tried ebay? Unlock is cheap as $1 and it doesn't hurt to try (unlock via IMEI - I unlocked AT&T and Rogers Focuses). If that fails, I recommend fastgsm, I've unlocked my own AT&T Focus with them, via USB (no affiliation).

It was carrier unlocked, as in I could place any sim in the phone and it would work. After I updated it on my Zune with Mango, it was loaded with AT&T's version and hence locked to AT&T. Now AT&T doesn't have the record of the IMEI in their database and aren't able to provide me with an unlock code. They were able to provide the unlock code for my other windows phone that I purchased from AT&T. Thereby lies my predicament. Let me try the ebay version, if not I hope FastGSM works. Thanks.
I was not able to get the unlock code from ebay. But FastGSM seemed to work wonders. I used their USB unlocking tool and it worked just fine. Thanks for the tip.
Hi All - I recently bought a Samsung Galaxy S8 from someone else. It worked fine when I was with T-mobile but when I moved to another network and popped in a new SIM, it asked me to "Enter network unlock code". I figured it must be locked to T-mobile so I reached out to them. They said my account met all the unlock criteria and said they'll send me instructions via email. I got the email two days later saying I need to use the "Device Unlock App". However, there's no such app on phone and there's no way to install it either (its not in the Play Store). I went back to T-mobile and they said since the device wasn't purchased through T-mobile, its not be a T-mobile "branded" phone. My questions are:
1. If its not a T-mobile branded phone, why does it only work on the T-mobile network? I checked its not rooted. It doesn't have any T-mobile apps and doesn't show any splash screen with the T-mobile logo.
2. Someone said that Samsung GS8 locks to the network of the first SIM you put into an unlocked phone. Is that true?
3. T-mobile says they've "whitelisted" my IMEI, so if I can somehow get the Device Unlock app I may be able to unlock it. Any idea how I can do that? Do I need to flash the firmware and install the T-mobile version or is there another way.
Thanks!
If you need to app, you can try here: https://support.t-mobile.com/docs/DOC-14011
However, as your phone is asking for the unlock code, the app might work but not unlock your phone.
You really need to do a network check and see which network is your phone actually locked. If your phone needs unlocking code, you might need factory level codes.
I think you should visit :

I have quite a few devices which appear on the LineageOS site as "no longer officially supported", such as the BQ paella device.
With these devices (quite annoyingly) you can't download images anymore and have to go and hunt for them on archive sites, but at least you can still build it yourself.
In fact I think it would be possible for someone to take on such a device and resurrect it.
The Kagura doesn't even appear on the unsupported list. Was it never supported by Lineage? I'm a bit surprised by this.
What is the best, most stable Lineage based ROM out there? preferably Lineage based? Is there one with source code available?
My son's one is acting up. It doesn't respond to inbound phone calls, and on querying the network for call forward status it says "SIM error". Putting the SIM into a different phone works perfectly so I think Sony has messed up something.
I think it's time for a custom ROM. 8.0 based is fine. It just needs to work.
I have compiled/built from source for other devices so I'm not frightened to do so with this one.
Any suggestions?
For the time being I won't be able to put a custom ROM on this
I followed these instructions https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader
at the end of the instructions "Tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked."
I have "Bootloader unlock allowed: No"

I suspect that it's because it's operator SIM locked.
Apparently I can unlock it myself with a tool called qunlocktool, but when I downloaded it my antivirus got quite excited.
I will contact the operator next week and ask them to unlock it. I had this phone from new so I think that they have to.

In my country (Poland) local provider doesnt allow to unlock the phone bootloader even after sim unlocking (also the charges are high)
Phone is now SIM unlocked, but I still have "Bootloader unlock allowed: No"
Hello,
I have an old galaxy S5 I am trying to network unlock so I could get rid of it. I called Sprint to get it unlocked, and after a long time being placed on hold, I was told the phone is not unlockable. However, they provided me the unlock code. I tried putting on a different carrier sim expecting to be prompted to enter the code, but that didn't happen. I only got an invalid sim error.
What can I do?
EDIT: it is possible to unlock, see below.
It is not unlockable with some "unlock code", you have to hack the modem firmware partition and flash it to the phone.
There was an online unlock service for $35 at http : / / idoneapps . com and I've successfully unlocked 2 phones with their service but the website does not work anymore, also they do not reply to email or facebook.
If anyone knows the similar service - please share the link, I'm interested too.
I've managed to unlock the G860P for international SIM cards, check this thread: https://forum.xda-developers.com/t/confirmed-sim-unlocked-s5-sport-g860p.3128965/
Can't seem to find this answer. If I bypass the SIM unlock part, unlock my bootloader and load a custom ROM, like LOS or crDroid, will the new ROM overwrite the SIM lock? Could I then use an international SIM (I live in the US) when I travel abroad?
T-Mo is giving me the run around cause I'm not a T-Mo customer, saying they won't SIM unlock for me.
Here's how I did it: Settings -> About Phone -> scroll down to Network Unlock -> hit Continue (mine's unlocked already so I only see "Continue" or "Cancel" for a brief moment before it says, "This mobile device is permanently unlocked and can be used with any carrier!" Also I was not a T-Mobile customer when I unlocked this phone (never have been) and did this over Wifi in another country. I didn't have to contact T-Mobile either. I recommend trying to unlock it from the menu because it seems a lot easier than attempting a bypass.
Is the phone giving you some kind of message/error when you attempt to unlock using this method? Or are you attempting an experiment with the phone for research/discovering additional SIM unlock methods?
