Hi everyone,
I bought a unlocked galaxy S6 Verizon on Ebay not too long ago. Recently, i did a factory reset on this phone and it went fine.
After rebooting, i stuck in 2nd step of the setup which is phone activation. It said it may take up to 5 minutes. However, after a while it will reboot itself. Even i leave it at choosing language step, it still reboot after a while.
I tried to boot in safe mode or wipe data again but it still doesn't work. Then, i flash stock rom with Odin, still it doesn't work.
I currently live in Canada so i think it can activate because of that.
Can anyone help me with this situation?
Thank you.
Try removing SIM card from phone before you use setup wizard

Hello,
I bought a G930VL (Straight-Talk) S7 a few months ago, but I'd like to use it on a different service, specifically ting, to save money.
I have read about others flashing the G930V firmware onto the G930VL and successfully using the phone on Verizon.
I'm unsure of what model firmware to flash however to make it work with ting (G930V vs G930U vs G930F), or where to find a guide I can follow to go about doing this.
Thanks for any help,
Matt

All I know is the U software is way better after ya locate a way to unlock the bootloader on the phone so it wouldnt interferes with other security part and lock ya from using it at all bricked software iv'e done it with a galaxy proclaim a while back and I really love it without cell service preinstalled locked bloatware tht ya cant completely uninstall em but uninstalled updates for em and disable em is comes close to u firmware
This is my first post... All I know about phones I've learned from this great website. I hope this is a chance to give back.
I've been playing with flashing either of these carrier firmwares on a few different Samsung phones. One being a production model the Galaxy On5. I do not know if this is an exploit or not... but this is what I did and the results of both.
SM-G550T - Galaxy On5 T-Mobile
T-Mobile Sim
I flashed SuperStarz Rom (Don't know how to link it)
His rom however is a Metro based rom..
I hit the device unlock app just for fun and to my shock it actually unlocked it. I've confirmed this with an AT&T sim card thus far. This model and account does not meet the criteria at all for the device unlock app stock to this phone.
Well I was curious..
SM-530T1 Galaxy Grand Prime
T-Mobile Sim
Tried stock unlock app... No success...
Flashed stock tmo firmware and tried again... it worked. Confirmed with a Wal-Mart family plan sim... and AT&T.
Please if anyone has the capability to try this and confirm it, let us know what happened.
Thank you!!
*I realize now this may be the wrong place to post this*
*UPDATE 4/3/17 - I performed a complete wipe and unroot on the On5... tried the unlock app for kicks... and it failed.
Because it was already unlocked!!!!*
Just did the same with the Grand Prime with the same result... seems as tho it might be legit. If someone else can confirm this I'll write a quick tut up for everyone. I also learned from my buddy that tried this after I explained what I was doing... he took the S4 Att and flashed tmo on it... and unlocked it. Flashed OG firm and remained unlocked. Or so he says... I will confirm later.
what unlocked it? the metropcs device unlock app?
Yes. And the Tmobile Unlock App on the other device.
Just tested with Galaxy Grand Express with success. Please... Anyone else confirm this??
Failing never felt so good!!! (On5)
So....
It seems to work well with later production models... Samsung Tmo Metro Att... and minutes ago with my Tmo sim, an older LG Boost phone.
Pls Anyone with any type of multi firmware capable phone, able to flash tmo or metro firms with the unlock app.. try this and let me know the results. I will be posting a full tut with screens in the AM.
I'm pretty sure I'm dying from H1N1 or Sars.... when I'm well enough to think I'll post tut.
metro galaxy grand prime unlock?
I have a MetroPCS Galaxy Grand Prime I'm trying to figure out how to unlock. I rooted it, flashed it with a paired down stock BUT I think that paired down stock got rid of the 'device unlock' app that was on my old Samsung Galaxy Core Prime because when I used that app on THAT phone it worked perfectly but I don't know how to unlock this phone or even if it IS locked (have no clue how to find out if it is). I ordered a global FreedomPop sim card to stick into this phone and give to my little girl (I want it for the tracking capabilities only for the most part, the rest I'm locking up).
This is the closest thread I can find about this subject. Any help would be deeply appreciated. I'm not a super genius for phones or programming but I can figure out how to get into the build and tinker if given the right instructions. I don't even know the mechanics of how phones are locked, though, so maybe that won't work. Again, not a super genius. Thanks, y'all.
Hi, i tried this today with a Galaxy on5 Tmobile (G550T) and didn't work. Had latest firmware installed, then installed twrp, backed up stock rom and installed Superstarz rom. MetroPCS device unlock app keeps saying 'Unlock Failed'.
Just reporting so others don't try in vain.
Yep, it's an oldie and moldie!?
I want to start with saying sorry I'm not very savvy in this stuff so forgive me ahead of time. My little sister was goofing off with me phone trying to mess stuff up and somehow managed to do a full wipe including removing all firmware from my phone. My phone carrier sent me to samsung who told me they have no records of my model number ever even existing so they aren't able to re-flash my phone. I eventually found a rom online and flashed it but this one won't connect to data for internet. The model number is SM-J700M and it's a Samsung Galaxy J7. Please help! I don't care what fancy features the Rom comes with or if it's rooted or not I just want my phone to work again
Hello.
Got a free phone from a buddy S21 5G. I am wanting to swap it for the S10* 1tb I gave my wife to use it was a bit expensive. So I'd rather ti go back in the box.
Popped the sim in it, it works makes calls sometimes, sometimes not. Texts seem to always work, I am currently on ATT I would prefer to have that firmware as I live in the stick with ho cell service. ATT has wifi calling which is pretty much a necessity here.
So what exactly do I need to do to get this off the VZN fir
Hello. Could you all provide me the links for what I need? Found a link that had a patched Odin plus the firmware. I installed in booted how I was suppose to. Tried to install in and it errored out. Also. I do not know what file to select for the user data selection, I do not mind deleting all data as it 8s hacked up and can put ti back with smart switch.
Hello, did you manage to flash the phone?, I'm stuck with a similar case, mine is a factory unlocked unit from Verizon, it turns out that even if it is factory unlocked, is locked after a few minutes by verizon, I have tried everything to get rid of the VZW firmware but it seems that Verizon locks the bootloader so I can't flash it (it passes om odin and everything but the firmware doesn't change)
I even paid SamKEY credits to change the CSC but it didn't change either.
