[Q] 'Permanently lock' stock rom (Need Help Please!)

I brought the phone via a retailer in Hong Kong and came unlocked, I had tested the phone with a UK sim card and it worked nicely (able to pick up HK networks), brought it back to the UK and was able to make calls and use mobile data.
I recently tried reflashing my phone back to stock rom, it worked however I lost my phone function, I thought the sim was locked however I had tested the sim and it work with other phones. I also typed in the code 2945#*802#, which gave me the menu with all the unlock functions, however after pressing the 'Network Unlock' I received a message saying 'This phone is permanently locked and can not be unlocked.'
Any suggestions to bypassing this or fixing this problem?
Many Thanks! ^_^

samsung galaxy S4 unlocked asking for SIM network unlock pin

Hi guys
I recently purchased an S4 from an on-line professional seller, the guy apparently owns a physical store but sells some phones on-line
when the phone arrived, I turned it on without the SIM, insert my home's wi-fi connection password, and the phone started to update both apps, and the OS to lollipop
I installed the backup I previously got from my old s3 mini, installed all my apps from playstore, and once I installed whatsapp, I turned the phone off, and than on again, this with my SIM since whatsapp has to confirm my number
The phone accepted my PIN code, whatsapp accepted my number and restored it's backup, but the phone also asked for this SIM network unlock pin
I told the guy what's happening, he told me he would send me a new phone, but I suspect this can go wrong
If that's the case, can anyone here tell me how can I overcome this SIM network unlock pin issue ?
thanks in advance
Regards
Antonio

If the phone were unlocked for use on any carrier, you would never see the SIM unlock pin request screen. Since you are seeing that screen, the phone is not unlocked.
To resolve this, root your phone and downgrade the phone's modem to an Android 4.2.2 version. Find a copy of RegionLock Away on XDA or through Google, copy it to your S4 and install it. Run it. Afterward, upgrade the modem to a more current version, and enjoy.
That's roughly what I had to do when the SIM unlock screen popped up on me.

Which s4 do you have? If it is the i337, region lock away may not work as you may not be able to downgrade the modem.

network unlocking 6p

hi, i just got my (second hand) nexus 6p and so far i like it alot.
updated to 8.1, unlocked the boot loader, installed twrp amd magist to get root all working fine.
the phone seems to be locked to vodafone (uk) as it works ok with a voda sim but when i try a ee sim or 3 uk sim it will not register on the networks and says emergency calls only. the thing thats confusing me is that it does not ask for a unlock code when i try another network sim, every other phone i had has always asked for a code to unlock it. am i missing something or is there another way to input a unlock code if / when i get it from voda or a third party unlocking provider?
cheers / thanks

You might be right but the solution is there check out this page https://support.vodafone.co.uk/Usin...one-device-if-I-m-not-a-Vodafone-customer.htm

thanks to a message from Exodusche my problem is solved. the phone is not network locked at all, when changing the sim for some reason i had to turn off the security pin then reboot the phone and as if by magic after that i had service and everything working fine. some sort of glitch in 8.1 i guess.

j3 320fn eu model almost bricked keeps promting for PUC network unlock code

Hi all long time user of the site but never been registered as never run into issues such as this below.
Recently family member took out sim of their locked three IE phone and tried to put another sim in into samsung j3 2016 sm-320FN model, one thing lead to another got message promoting for pin, even when original sim was put back in which never had pin lock on it and tried different pins which propably triggered some sort of lock on the phone but original sim works fine in any other unlocked phone.
When i took hold of phone i tried to root it and got hit with frp lock, eventually untied it from google account and managed to get lineage room onto it v14- no backup was made of original firmware my naive thinking on this part .
i used odin v3 with twrp 3 wiped cache david data and systems before hand. got it rooted with SUroot, and after then installed latest twrp to get other rooms onto phone.
Now strangest issue is that original sim works fine on any other unlocked phone but putting it into J3 i get hit with network unlock code PUK, at first tried support from three Ireland they thought it was sim blocked after numerous different codes it would return same message network unlock failed, eventually got hold of network unlock code, but entering it in lineage room OS it would say network unlock was successful but there would be no bars on sim, checking reception and signal it would show as none towers discovered and no signal received, following that every time phone is reboot it still promts for same code, figured it might caused issue with current room and downgraded to lineage v13 but still wouldnt see any reception the signal bar appears grey, final conclusion was maybe wrong unlock code was sent so requested another one which came back same as previous from mobile provider.And all repeats if entering code says unlock is successful but no mobile signal detected, tried 3 different roms and always keep getting greyd out signal icon and promt to enter puc unlock code.
In the process managed to wipe completely all rooms from the phone and did DBA backup restore via cmd and managed to get different room running on it RR-OS but same happens each time phone powered up inserting any sim including original network sim promts for code, after entering it, says successful and no bars or signal.
phone is only good to use for wifi browsing now, and im out of options to figure out whats the main reason also cant find original firmware.
Spent 2 days flashing rooms and unbricking phone but seems mobile signal and network unlock fails for unknown reasons to me. tried to list every step ive taken and software used.
If anyone has any idea whats causing this would appreciate any help, even thou phone is old by now but still enough for person that uses it.

S10 + Sprint Unlocked issue

Hi Everyone,
I just bought a brand new s10+ from marketplace. I ran a full imei report and everything is clean & not blacklisted. It was a sprint phone however the provider I use is consumer cellular (uses ATT towers). When I put my sim card in it obviously said invalid sim and request it get unlocked. I wasnt concerned because I was going to convert it to unlocked anyways via odin like I did my note 9. I reflashed it via odin with the u1 firmware. However the same thing is happening it keeps saying invalid sim and the button for mobile operators is not showing. I have a tmobile sim card and if I put that in it works fine. Being though tmobile and sprint are the same thats why it works fine. I also have a ATT sim card, If i put that in I get the same invalid sim message. So it still appears to be locked somehow. Only sprint / t mobile sim works. I thought by reflashing to unlocked it would unlock the phone sim.
Just to be clear the phone is brand new and never was attached to any account.
Any ideas? I dont know what to do here.
Thanks!!

As I understand, phones that are locked to a network are not just software branded... also the phones hardware ID. So flashing a generic firmware is not enough. You need to get the phone unlocked from the phone's original operator

I found out what I had to do. I had to use a remote unlock service to remove the software lock on the phone. Its fine now. Thanks
