Hey Guys,
I have had one heluva time trying to unlock my Rogers Galaxy s4. I purchased an unlock code, which did not work. I tried through service mode. Then I tried flashing the rom to a factory rom, which has now disabled my cellphone reception. At this point I am trying to put the stock rom back just get my phone working. Is there anything else I can do?
FastGSM.com has been the "last resort / saviour" for many here when service menu didnt unlock nor purchased-code.

I also used fastgsm to unlock mu i337m using the usb unlock method

Hello, I used the SIM unlock method from the thread here on XDA and was able to successfully unlock my phone and use it on a foreign network. A bit later I had a problem with my Bluetooth so I did a factory reset, and now the phone says 'sim not allowed mm #3' when i put in a foreign SIM.
The frustrating part is that when I go to the unlock menu there is a list of various logging methods, but every one of them says 'Phone is not personalized' which means the phone is unlocked, so there is no way to reenter an unlock code.
Is there a wwayas to check and change the software lock status?
Hi! I am having major issues with my s4 i337 after switching from att to tmobile. The phone was unlocked so I took it upon myself to unlock it. It is unlocked but sometimes or rather most of the time does not pick up the network. When it does have data connection, it is Edge. I flashed the NC1 to root my phone, then reflashed to NJ4 (to unlock) but now nothing works. No wifi, camera fails, no multitasker, no voice assistant. Please help!!!!! I don't know what to do. I should have never unrooted it to unlock. I should have paid the $35 to get an unlock code. Can I fix this?

S7 Edge permanently locked to AT&T network (Too many network unlock code attempts)
Hello all!
I've moved to Korea with my fully purchased AT&T S7 Edge (SM-G935A) from the U.S. I went to a local authorized phone service shop in Korea and purchased and linked an SK Telecom Nano USIM 3GB data sim card to my phone and then entered in too many unsuccessful network unlock code attemps. I wasn't aware that if too many failed attempts are entered, that the phone would lock permanently to AT&T network :/.
I then contacted AT&T and got the official authorized network unlock code, but that isn't working. Neither did the unfreeze code I purchased from an unlocking site. I then found the XDA forum and successfully flashed my phone to G-935U (http://forum.xda-developers.com/att-s7-edge/how-to/updated-935u-935a-live-links-pi3-t3501686). After inserting the prepaid Sim card, I'm still receiving the network unlock code screen where the AT&T network unlock code, unfreeze code, and codes on Sim card packaging are not working.
Can anyone advise any solutions? Is there a way to reset or get around the hardlock / permanently AT&T network lock?
Thank you,

I have had hard locked phones before, here's how you can get it fixed. If its still under warranty, and if you can get it to samsung usa, tell them your phone is stuck due to a bad update. They will reflash your phone, and when they do this, with their methods, it restores the modem firmware and the original sim's lock(no more hard lock). & they will reprogram your imei and serial. So your unlock codes will work now.

Hey guys, I've had an unlocked LG G2 D802 I used for 2 years, then I gave it to my sister, she uses it in different countries. It worked without problems in Greece, now she's in Italy, she tried to insert an Italian SIM card, but it doesn't recognize it. I told him to type 2945#*802# code in the dialer so she can check if there's a lock or something, now the phone says "This phone is permanently locked and cannot be unlocked". It shouldn't say that as it is factory unlocked, can anyone help me out in this? Thank you.
Close this, a new SIM solved it.
wipe data from factory reset or flash new firmware
