Ok, I have a S7 I just bought from some guy on Craigslist. He said it's unlocked BUT.. I put my AT&T sim in and it says "INVALID SIM CARD" Its a SPRINT phone and I want to use it with my AT&T for coverage reasons. Can someone PLEASE tell me a beginner how on earth to make this happen step by step. Do i need to root it, is it really unlocked if it is telling me this on my valid sim card that works in my other phone, if it is LOCKED how do i unlock it, Do i need to ROOT it to unlock it , do i need to flash firm ware... I am willing to PAY someone to log onto my computer via TEAM VIEWER to unlock it or flash it or whatever needs to be done to make it work. I am online on SKYPE tonight for a few more mins so if you want to give it a go and know what your doing contact me at thereverendd on skype. If i dont answer, I will when i get on for sure next time. But I am here for a little while longer tonight... Thanks to all in advance..
If it's the same as the S5, you can't SIM unlock by rooting or flashing firmware, you'd have to take it to an unlock shop, or pay for an online service
Not sure about the US, but in the UK we can call the carrier and request an unlock code once the phone is over 6 months old on that carrier (Pay n Go) or contract some carriers provide an app to request unlock
I'm new to the S7 though so there may be another method

Did you try inserting "a SIM card not attached to your current provider (e.g if you have T-mob use an ATT SIM CARD) and turn on your phone?" (credit sanfranx415 post) edit: maybe try a different gsm carrier in the same country you reside.
From what I have read and understand different versions of busybox will work or are compatible for different things (maybe somebody will tell me if that is not accurate).
Here is a video that might help.
Good luck!
Try contacting t mobile and tell them your going overseas for a few months and want to take your phone with you and is there a way to unlock it so it can be used in another country.

When you insert the sim card and power up the phone, as you unlock it it should give you a network lock screen that only lets you use the phone after inputting the unlock code.
I've been searching for a number of hours now, and I haven't found the answer I need. I have a rooted Galaxy Avant from T-Mobile with TWRP installed, everything is backed up and ready for any customer firmware to be installed. I need to get this phone unlocked. T-Mobile says they won't unlock it because I haven't had an account with them for over a year, but it was a prepaid service plan and I bought the phone outright. They just refuse to provide me a code. I understand that even if I HAD a code I would have to flash the MetroPCS ROM and use IT to input the unlock, but what I'm hoping for is a way to unlock with a customer ROM or something like that so I can use it with Cricket. Everywhere I've looked has either lead me in the exact wrong direction and tried to get me to purchase an unlock code, or it has only told me how to input an unlock code I already have. I'm fairly knowledgeable about all of this, but I'm stumped. Anyone who can give me a hand with this would be greatly appreciated. Thanks!
Hi !
I haven`t found any thread for sim unlocking for this device but you can post or search in here https://forum.xda-developers.com/general/help/discussion-galaxy-avant-t2845229
Good luck !
so i requested an unlock from sprint but its still locked. not sure if sprint is just ****ing with me or if i have to be on the sprint firmware, because right now im on the Unlocked firmware.
Might possibly have to be on stock sprint, but if you had them unlock it, they issue a update to the phone, or at least thats how my s5 and s6 was done, and that was only for international not a US carrier unlock. It did take a few days before it was issued to the devices i had so give it another day or so and if its done done, then i'd contact sprint again and ask them to re-send it to your phone.
Keep in mind if its a international unlock, you still wont be able to use any other carriers sim domestically in the USA on the device as it will remain locked to sprint Again it took 2-3 days before my devices received the unlock from sprint.
If you flash the eng boot/unlock files i can unlock it remotely if sprint doesnt come through for you

Contact me via PM , let me know what build its currently on and the files, depending on what build you're on, are the S8 unlock files posted in this section already. Those may not work depending on what build revision you have on the phone currently. With those files, you should also be able to flash back to sprint's firmware via the guide posted in this section as well.
I've been busy lately but i'll help ya out as much as possible.. Again PM me with info and we can go from there.
I can help if you need help still? Pm me.

Hey there,
I got a S8 phone from a coworker, that belonged to their ex. It was locked to their ex's google account. She gave it to me and said I could have it if I could get it to work.
Ended up flashing it with the T-mobile S8 firmware but only to find out that it was unlocked to the Sprint network. She is no longer on his plan so could not call Sprint to unlock it. And she doesn't want to call him to deal with it. Anyway, so no problem. Can unlock it via a 3rd party. Went with unlock base but still waiting for the code.
From what I read on the site, I will need to insert my sim and it will ask me for the unlock code. Unfortunately, when I insert a sim currently, it just says to contact sprint. I'm guessing this is due to the T-mobile firmware.
Will I now have to install the Sprint firmware to get it give me the unlock prompt upon sim insertion?
And after it's unlocked, can I go back to the T-mobile firmware?
Thanks for all the help in advance!
If the IMEI is paid off you can request an unlock from Sprint, if not you would need to use third party.
You can attempt unlock yourself but you do it at your own risk.

You currently cannot unlock any US version of this phone.
Never
so this phone is impossible to aquire root permission ?
Yes. It is impossible to root (unlock bootloader) currently. This phone may never be rooted. Brought one for my spouse, she does not need root. When I found out that it cannot be rooted, I passed on buying one for myself. Nice phone.
Yeah but its about the challenge of discovering the formula. You guys always find away when we get a good thread going, and put are ideas together.
Plus got rid for of my verizon firmware and flashed the usa unlocked

at least i could get rid of all the verizon bloatware and most of samsung bloatware too but phone really not compatible with other network providers, it prompts me for verizon network unlock code if i put a diferent sim card att and sprint.
You need a sim unlock to use a different carrier. Check with Verizon. People that purchase this phone should not expect it will be bootloader unlocked.
Well that sucks, but your wrong I did network unlock without any codes, I just changed the apn settins, i didn't pay nothing to no one. And it is possible to unlock bootloader if u got 65 dollars, any Samsung usa variant from s9 and up https://forum.xda-developers.com/t/...unlock-for-samsung-us-canada-devices.4215101/ or here: https://forum.xda-developers.com/t/sampwnd-usa-model-bl-unlock-info-u-u1-w.4201689/ , but I can't afford it so im going to have to figure it out on my own like usual, plus I only payed 15 dollars for this phone and the screen is already cracked, I know how to replace it but Samsung screens are such a pain and expensive, im waiting to find something worth wild on offer up so I can finish trashing this one.
