My brother bought for me a Galaxy note 10.1 from Globe carrier when he was being in Phillipine, and it was unlocked. This tablet still worked well until I take its sim card out, and use it for my 3G USB. This USB seemed to be broken down, so that my computer was frozen every time I plug it in. I put my sim back into galaxy note 10.1, and a problem occurred. My Note 10.1 cannot register on network even I see a full signal bar; meanwhile, a notification showed that "the selected network is unavailable". When I try to make a call, it's appeared to be "Not registered on network". At first, I think this problem can simply solved by changing the sim card, but the real tragedy is that this problem continue occur regardless how many sims I buy from many different network providers. Those sims still work on other devices, hence this error certainly is from my tablet. Its firmware is stock 4.1.1 and rooted, I have tried to solve this error by reset factory, unroot, change to another rom, but they're all useless.
When I visited Samsung service center, they told me that my note was relocked. Would anyone mind showing me how to unlock it again:laugh:
Sorry for my bad English! Thank you one million time:highfive:
May be you should flash some other rom which is not region locked like German, again very few users have a locked note so doubt you will get an answer over here
A suggestion try note 2 or S3 forum they are built similarly see if you can find a post on how to unlock it I am pretty sure it will work on this to (Warning dont flash S3 or Note 2 rom )
Hey guys,
Bought a Samsung Galaxy S5 off craigslist recently and didn't realize it was in retail mode until after I got home and started playing with it Ive tried both of the two popular master passwords: 5444 and M729Q16K8546 and neither of them work.. Phone is for the Sprint Network.
Any thoughts on how I can remove the retail mode app so I can use the phone?
Apologizes if this has been asked elsewhere on the forum.
Thanks for your help.
iirc "retail mode" phones physically lack the modem chips and antenna. It's a Galaxy S5 Touch instead of phone.
edit: more info here.
Hi XDA Members !!!
Greetings of the Day !!!
I am need of your urgent help .
I recently bought a samsung galaxy S7 sprint UNLOCKED (SM-G930P) from Ebay . Firstly i was able to use my T-mobile sim card in it and LTE was also working well, but the inbuilt as well as other apps were crashing . The apps like Whatsapp, Inbuilt camera app and other apps were crashing and i was getting a message as "Unfortunately the app has stopped Working".
So i took my phone to Samsung service center and then they re-flashed my phone , but i was still facing the same problem.
I told them this and then they replaced the motherboard of the phone (Replaced PBA, this is what mentioned on the receipt which i got from Samsung ).
The phone is running the latest firmware and Android 6.0.1.
When i received the phone , i inserted my T-mobile sim and now the phone is saying "Invalid Sim inserted" . Now the phone is only working on Sprint Sim card. <<I am so angry on Samsung for this **** .>>> .
MOREOVER There are options missing in the settings menu such as "mobile network, hotspot and tethering, wifi calling and others." and also getting the Hands Free activation every time, but the phone does not have any sprint apps installed in the phone and no sprint logo while booting the device up.
i called the sprint service center and asked them, they said the phone is unlocked.
Please help guys , i need this to be fixed asap . I need the phone to work on different carriers.
Can you please let me know, how to check if the phone is unlocked or not , on the phone itself.
I don't want to void my phones warranty . Please help .
Thanks in Advance !!! Cheers .
Hoping for the Best .

Hello all!
I bought the Samsung S7 phone in unlocked condition from eBay in US. Then I had to move to India for work related purposes and I was able to use the phone using an Indian sim. The phone developed charging issues and it was not charging. So I had to send it to US where Samsung changed the motherboard. Now, I received the phone which is working but it shows invalid sim if I put any Indian sim. It seems Samsung have restored the phone to original settings which is locked to Sprint network. Samsung tells me to contact Sprint. While Sprint says that they need the account details or confirmation from the person who bought the phone from Sprint. The eBay account from which I got the phone does not exist anymore.
I think I need to unlock the phone so that I can use other sim in India. Could anyone suggest what could be done here?
Thanks!
