Samsung Galaxy S8 Security - How failproof is it? - Samsung Galaxy S8 Questions and Answers

Hi, I was with my friends earlier and this guy kept saying how his S8 is much safer than all other droid phones due to the Samsung account thing. This got me thinking...
So by now we all know Google Lock aka FRP is easy to bypass. And I dare say Samsung lock can be bypassed the same way, although I got no knowledge in this.
Imagine he loses his device abroad and he gets both Samsung and Google locks wiped along with a recovery factory reset. Is there a way to track the phone via IMEI? Even in another country? Can he still use his samsung account to track it?
ull disclosure: I placed a few beers as a bet that I could make his phone clean within minutes if I had a USB cable and a laptop with internet connection, he agreed. Make me drunk boys.

Change Carrier Banner on Lockscreen without root?

Hey guys,
I am a Sprint Employee for a third party company. New company policy says that if you don't have a Sprint device that you have to keep your phone in the back during your shift. Which is stupid since we have to use our phones while we work/use it as a selling tool, but I understand where they are coming from(it'd be bad to try to sell someone On Sprint when I have Tmo lol).
I asked my DM if we changed it to Sprint/blank would that be accepted for us to be able to use our selling tool on the sales floor and he approved. Normally in this situation I would just used Xposed and get rid of it all together. As we all know Sammy dropped the ball on that one.
Anywho I searched the web trying to find something that can do this without root access and I couldn't find anything. I was wondering if any of you guys have an idea/way that you know of to do it without root. It was so strange not using my phone during my pitches. T_T
I don't think it's possible without root, but maybe you could take the SIM out and just use it on WiFi while at work. Or use a different lockscreen while you're at work. You can turn the lockscreen off completely, too.
Samsung Galaxy S7 Edge

FRP Lock - Remove/Bypass Assistance Requested

So I have a Samsung Galaxy S7 Edge, or rather my friend does but he brought it to me for some work. That being said he has about 20 different Gmail accounts with about 20 different passwords and he doesn't know which one belongs to which and I factory reset the phone part of discovering which one was the master account. In any case I try to use Chimera to do an FRP unlock but unfortunately because it is on Android 7.0 it did not let me do this. I also try to roll it back to 6.0 or 6.1 rather butt same.
I read a few different online guides and one of them was on how to do the network unlock by doing a bypass of the Wi-Fi to get around the initial settings and then from there you open up the terms and policies with the long press and allows you to open up the app manager in you go to settings there. The problem is is that unfortunately that seems be disabled on some security update to happen for 6.1 on one of the OTAs at some point in time
I saw there were few different tools out there but the one that I was able to read the guide on seem to not work at all because when I hit the button the response I got was green but the diamond ever popped up if that makes any sense. In any case it's 2017 about halfway through the year and it seems that every FRP unlock has changed modestly since 2015 near the end of the year.
Is there a current method on how to refresh that are peel off whether it is the change out Sims 2 loaded if in firmware to do something. But the phone is not even to root it yet but I intend to do so after we get into the phone directly. Please provide any assistance if you have it.
Thus, uh... Really sounds like your "friend" stole this phone ?
No. If we provide you any solutions even if what you said is true, other people with stolen phones can bypass the very measure that Samsung incorporated to disable stolen phones. If it is truly your 'friend's device, tell him ANY Google account he used with the phone will get rid of the frp lock. It doesn't have to be a specific one.

Not true at all.
It has to be the account that was logged into at the time of the reset. You can easily link your Google account to the phone and it still won't allow you to use your account to open it back up.
Not a troll either but in about same place this guy is just mine is legit
So basically this is what has got me messing around with flashing and trying to mess with the firmware also different settings on the android system. However so like the previous user which actually does sound like his "friend " did steal it. This one is a S7 I actually purchased in la. It is not a nightmare of a drive but for $200 it almost is. Im almost about to sell the phone on ebay. I immediately after purchase spoke with t-mobile and was told phone was good just it was sim locked. I would need to sign up with there service. The phone was supposedly frp free and sim unlocked for any carrier in the americas and europe. Very far from the case. I put my personal sim card in for att get the same network id message or the puk when i enter it wrong have tried even new att sim cards. Att is offering me the same deal but said to prepay for 90 days. I am not sure how this makes sense since how is unlocking the sim also going to unlock the google account from previous owner??? I keep trying different methods with odin and smart synch. Any other random apps basically and best I do is make a paper weight or can get to my imei on a legit dial pad however I try to go to even change to imei from previous phone which is still active just broken screen but still have the same issue. I am thinking at this point mabye t mobile and att are the hassle here and half the videos have helped me about 10% from youtube and different docs. I have been going on trial and error for about 2 weeks now. Called t mobile back last night same story just due to all the the theft but she again checked my imei on the device and said it was all good still to get back to them when ready to commit to service. yeah.... right. But Im trying to avoid just throwing the thing the next time I brick it or sell it on ebay. I am doing everything correctly and all is legit. Even trying to transfer my other phones info if needed. Obviously it is still sim locked and has frp through google. Please help any ideas. I am about to probably throw it before I ever get the chance to sell it is that frustrating. One thing I cannot get to work correctly is rooting. I even went loaded apps on sd card went into apply updates or data from sd card and reads folders but not the program im trying to use for rooting. I have done multiple times on many devices. I dont know if t mobile is just like jumping through hoops or am i just skipping some small detail somewhere in the process. IDK HELP PLEASE ANY FEEDBACK IS APPRECIATED. I AM USING THE NOUGHAT FIRMWARE, I TRIED ON MARSHMELLOW AND EVERYTHING GOES THROUGH THEN AT END GETS CAUGHT UP WHEN I GO BACK TO UPDATE BACK TO CURRENT FIRMWARE.

Nothing I read stated that you have, or even know, what an FRP Locked device [is]. I'll skip badgering you with pointless questions & just jump straight to giving you solutions:
1) Flash & boot into TWRP Recovery > Wipe the IntrnlStrg/Cache/Dalvik/System (system is key > Flash stock firmware
2) Find my Galaxy S7 & S7e FRP Bypass post here on XDA (for advanced users)
3) Do more research
I'm not trying to sound like an asshole so I apologize if I come off strong - I'm [almost literally] sick of reading all these f*cking crybabieson XDA, or other sites, begging for somebody to solve their problem instead of doing their own research & trial error runs. I have successfully bypassed FRP on 30+ different devices from different carriers with different security patch updates on Lollipop-Nougat OS by using various different methods that are(n't) common (S7 included)
Bypassing FRP is Elementary school difficult. This sh¡t is checkers, not chess. My spiel is done with
Good luck.
I think I ended up with this guy's phone from Craigslist...

I have a similar model that I got off of Craiglist:
- Samsung SM-G900T
- completely up to date
- freshly re-imaged and FRP locked
- no soft FRP bypass works (probably updated to the absolute most current version of Android)
- not detected by Odin/Octopus (appears USB connectivity is disabled - it won't even show up when plugged in, anywhere).
- doesn't appear that USB debugging was enabled before the reset
- ADB and download mode just sit on "downloading/looking for filename" - I assume both options are being blocked from the USB connection, so there's no activity on the PC/Odin/tools when I use these options
The only activity when plugging in is that on the phone it goes 'blip blip' and has a little graphic over the USB port.
I liked your suggestion of do more research but this is stumping me, mostly because the USB appears to have 0 life other than to charge the phone.
Only thing I have not tried it OTG cable apk but I'm not hopeful. Friend is giving me a cable when I see him in a few days.

• A new cable would be ideal
• Try different versions of Odin
• Reinstall Device divers
What OS version is installed & are you able to boot completely?

Open to anything! A different came (not new) doesn't do anything when I plug it in. The cable that came with it charges it and is detected by phone, but not by PC.
I'll go buy a new cable and see it it does anything. Meanwhile I'll try all the previous versions of Odin. I also suspect the most recent version might not be doing the trick for some reason (having rooted and flashed about a dozen phones on prior versions).
It completely boots either Oreo 8.0 or 8.1 to the Welcome setup wizard every time. None of the soft tricks get me any further than the FRP.
Want me to post a picture or anything? Download bootloader or FRP screen? I've also ordered an OTG cable to try out the apk work around.
edit: also tried jodin on a mac mini and odin on a different laptop. I have an older laptop I may try too.

Site was being screwy - sorry for the PM man. Same as below:
Sorry - I used an S5 for years and miquoted you the model. It's an SM-G930T (T-Mobile S7) The drivers on both systems are all up to date as well. It's 0x0, qualcomm, k1 s3 if that helps.
Again, sorry for PM, just curious on your thoughts with this one. Also wondering if you know if Download Mode would supercede any FRP or security settings. I keep trying various versions of Odin while connected in Download Mode - no COM port getting assigned.

I got ahead of myself and still need assistance.
I've managed to fix a few things (it would fail constantly in odin and result in a failed firmware screen upon restart).
Current situation:
- USB debugging was not enabled
- FRP is locked on Android 7.x
- I can upgrade/downgrade the firmware, but upon restart it pops up "Erasing" then "Installing updates" then "Erasing" so its basically undoing any security unpatching I'm try to do. Currently it's got G930TUVU4BQG5 July 2017 firmware, but the security patches to prevent RealTime, SideSync, Smart Switch and other dialer programs etc seem in place.
- I can put a COMBINATION firmware which gets me into a factory binary, but I don't see anything in here and have to reflash back to G930TUVU4BQG5
- Spamming RealTime to repeat dial a number shows me the traditional "calling" screen, but bluetooth, end call, etc are all greyed out.
- I have no SIM installed.
This guy did an FRP unlock (most up to date security patch) in 10 minutes. EXCELLENT service.

Samsung S8 AT&T SM-G950U - pattern locked out, can I install custom rom?

Anything I can do with this phone? Found it in the bay last friday, it's pattern locked and doesn't seem to take phone calls or allow me to contact anyone to retrieve..
Would I be able to install a custom rom or something to actually utilize this phone, does it need to be like IOS jailbroken first also?

Needs factory reset and Samsung frp lock removed. Att and Verizon can block signal to most phones that have been reported lost - stolen .
Sent from my SM-G955U using Tapatalk
ty, possible to use to watch movies on, if I ever get frp lock removed? I only see services that I have to pay for, I'll probably just leave it on shelf or something for now.
If you do get FRP removed, you will be able to use the phone like normal again.
If the Verizon, AT&T, T-Mobile or Sprint blacklist the phone, a SIM card will never work in it again. But it will still function like normal but with no SIM in it. WiFi device only.
Thanks, after hours of searching for a solution, it would appear I can't remove FRP by any means that I've found online.. So seems I found a 700$ brick lol.

Locked S8

A month ago while doing some off road bike riding I found a S8 on the trail. I call Verizon and they said they would get back to me on that to do with the phone. They never called back.
I've placed a ad on Craigslist and have called Verizon 4 times. No one seems interested in the recovery of this phone. I could use it to fly my drone but it's locked. I tried a reset but it's asking for the old Google account info. Is it possible for me to root this phone so it can be used on WiFi? My other option would be skipping it accross the San Francisco bay. I wonder how many skips I could get.
Thanks for any input on this post.

You could just flash stock firmware on it, using Odin.
Flash unlocked (G950U1) firmware on it and wipe it through recovery. Should allow setup without needing the account linked to it

No, that does not erase frp. Frp bypass discussion is forbidden on XDA, as the #1 reason to use it is to resell stolen phones.
To OP there are enough resources on the internet that you should be able to figure out whether or not this is possible yourself.
You could also just figure out what carrier it's on, walk into their store and hand it to them so it can be reunited with its owner. I know if I lost my $800 phone I'd be pretty sad. Definitely better than destroying it, seemingly out of spite
There is a combination file which you can flash via odin to bypass frp
google it for more info

thank you for your input. I'm not sure how but I will try to close this thread down or delete.
Because of my busy schedule I was trying to have verison send me a mailer so I could send them the phone. Also I was just kidding about skipping the phone across the bay. I would never do that. I have left the phone on since I found it expecting someone to call it so I could find the owner but there has been nothing. The owner probably got replacement through insurance leaving this phone disconnected.

Device locked by former owner's Google account?

Hi there,
It's been a longtime I didn't post out there.
A couple of weeks ago, I drowned my Galaxy M31 (bummer!), couldn't revive it. Being broke, back to my good old dumb-phone I use while skating (it's OK, actually).
A nice colleague of mine proposed to lend me her old Galaxy S7 she replaced a while ago by a newer device, telling the battery is a bit lazy now... Thanks to her.
In front of her, I reboot in recovery (she didn't even knew there was such a thing), factory reset the device and off we go.
Back home, I flash the last available Oreo firmware (just to be sure, with the CSC part), let it boot and... yeah, Google detects the device was reset and ask for the previous owner's account, as far as I understand.
It's OK, it is to trick robbers stealing phones and trying to flash them anew, I suppose. Got two phones robbed, encrypted and all, I hope they were f*** with mine.
I feel like... a sucker, I should have been more cleaver and probably ask her to delete the Google account it was registered to (hers, her husbands)
Can someone please tell me if it is the right way to do it right?
Never had to do anything like that: so next Monday, she sign in with her email or phone number, her Google password, the device goes on booting/configuring skipping whatever time consuming setup, up until she's able to "cancel" or delete the Google account?
Thanks in advance.
Hi there,
It took some time, lack of actually, to get it unlocked by my friend. The device is back to me and running Oreo on my account.
Let's root it and probably upgrade it to Lineage 17 or 18 as I did with an good ol' A300FU.
