I have a rooted and unlocked i717 on Telcel mexico, i can navigate on internet with no problems but at the time that i try to use usb/wifi tethering it say "No data available or invalid sim" how can i correct this ?, it looks like the same problem apear on rooted/unlocked ATT i717 on T-Mobile.
I have Galaxy S2 phone bought from Japan and it was network unlocked by the carrier NTT Docomo.
I had been using it successfully in India with a local SIM card.
When it had the 2.3.6 GB version, it was working on roaming, but after upgrading to 4.0.3 ICS, on trying roaming facility, it has started giving network unlock error message.
Initially I thought it was a security message and tried the configured combinations. Unfortunately, after 3 attempts, it has got locked and not detecting any SIM nor asking for the network unlock code now.
Any possible solutions to handle this?
If rooting the phone and running the unlock software is the only solution then, which kernel to use for this?
Please do advise.
Thanks,

Hey guys, recently I've got an Alpha SM-G850A which is for AT&T. I live in Iran and the phone has been unlocked to work here, I was trying to get the Android Lollipop 5.0.2 for my phone. so first I tried to get the update from AT&T software update by phone, but it says that there seems to be no updates available for me, nevertheless on the net the guys claim that they've got the update, is it due to my location in Iran and my internet IP? (I used VPN too but again, no updates). I tried to get the firmware from Sammobile.com too, but there were no firmwares detected for SM-G850A. Can someone help please?:good::good:
BTW, I've got the cellular data from my operator, and it works, but I can't select which type I wanna use (2G, 3G or 4G). I mean there's no options in the phone settings to select the data connection type. NEED HELP!

Even tho the phone is working on other networks you will still need an at&t sim card to update it. There is no way around this as far as i know.
Type below code in dialer and select Device information. Now, if you scroll down you will have the option to change network type.
Code:

Hi,
So this device I bought from facebook marketplace and was told it's fully unlocked.
After inserting a different SIM, the device works for a minute, then shows an error saying it's not a verizon SIM and disconnects from the network.
I contacted Verizon and they're telling me that it's unlocked but I guess something in the firmware that prevents me from using the phone. I did a factory reset, now the phone setup won't finish without a Verizon SIM card. it stays stuck on that screen.
Is there a custom firmware that I flush this phone with and be able to use the phone?
Please advise.
Thanks.
Verizon A02S unlocked but not able to use on other networks. Need help unlocking
Hi you have to remove headwind mdm thanks
I have the same situation. Bought a Samsung A02S and it's from Verizon and was factory reset.
It boots to "HELLO" screen but won't let me initialize the phone without a valid Verizon SIM. I put an old Verizon SIM and it says "invalid".
How can I boot this thing to get to settings etc. to unlock it from Verizon?
