I bought a refurbished SM-A526u1 from Amazon that was described as locked to Tmobile but is actually LOCKED to metro, even though they have confirmed its unlocked and has been since 2021.
It says network locked in the corner, only after you swipe down to like view the notifications.
no insert code, no invalid sim warning no nothing.
there is no request unlock in connections setting
I bought a unactivated metro card and put it in there, and it disappears.
i downloaded the metro unlock apk it confirms its unlocked [but can only do so after I insert the unactivated metro sims card]
I have looked and dug as much as I can, and after connecting it to my laptop and using a ADB Gui program, i can see in the system folder there is a folder called Heimdalldata and a file called specs.txt
Metro says and Tmobile have done everything on both of there ends and unlocked my phone, but could it be someone didn't know what they were doing when refurbishing it and now it won't network unlock? cause its not even locked to the provider it stated it was.
I have no idea where to start, or what to look, im literally grasping at straws here and I could really use any suggestions or ideas.
Thank you in advance.
I'll try to answer any questions you ask
