Hey all!
Is there any way to implement anti-theft tech on the S5 that is resistant to a factory reset? Many apps are available to track a phone after it is stolen. However, all the thief needs to do is pull the battery to shut it off, pull, the sim card, power into factory reset and poof it's ready to be re-sold. Cerberus offers the best protection I've seen so far as it will survive a factory wipe if the phone has been rooted and a custom ROM loaded. However, even that can be worked around by flashing a custom ROM (which the thief may not know how to do).
Any suggestions? How do you guys handle anti-theft? Had 2 galaxy phones stolen over the past year so I'm looking for any and all advice here. Thanks in advance!

Enable "Reactivation Lock" in security settings, factory resetting the device forces the person to log into the Google account that was logged into when the lock was enabled, or they have no access to the device, even after resetting it

Re-activation lock only works when knox is 0x0 but that too can be bypassed by installing custom rom so...
I don't think there is the way. You have to pray that whoever will steal it is not an advanced user.
Reactivation lock does block custom recoveries as they use a custom binary. And if the user tries to flash through recovery they would need the user's google ID ( to unlock the reactivation lock). Though on other sources, it has come apparent that reactivation lock can be tricked (even in the latest lollipop bulid). As a extra measure you should password protect TWRP and encrypt ypur device to prevent any form of identity theft.
Yes it's very easy to break the user's lock screen since the information (cant remember either salt or hash, look up a Android Forensics blog) is stored in a database - settings.db and gesture.key . Someone could easily just delete the field for password.

there is no way or point in protecting phone to be stolen... if thief cant use or sell stolen phone will he give it back? no.. he will either crack it if this is possible or sell it for parts (screen, battery, casing).
Only reason to encrypt or lock a device is to protect personal data like photos.
Hi Guys,
my MOthers new Xiaomi MI A1 was stolen this week.
1. Now my Question, is it possible for the Thief to get on her Data?
Theroretically not, because the phone was on last official android update 7.1.1 (nov sec patch)
Phone was saved with a Fingerprint and PIN and ohone was encrypted.
2. Is it possible for the Thief to hard reset the phone via adb or fastboot to got a use for the phone (resell etc)
Thanks
Even if he would format it, the phone will ask to log into Google account of the user that was logged in before formatting. I doubt the thief is smart enough to bypass it.
1. did you enable "require pin/password for phone startup"? If yes, there is probably no way to decrypt the data without the PIN. If no, thief could unlock the bootloader (Xiaomi is the only phone I know which doesn't perform factory reset for this action) and use the default encryption password to mount the data partition in TWRP.
2. factory reset will trigger FRP, but it's probably quite easy to bypass it with a bit of patience.

Yes PIN was set on startup.
" If no, thief could unlock the bootloader (Xiaomi is the only phone I know which doesn't perform factory reset for this action) and use the default encryption password to mount the data partition in TWRP. "
How can he unlock the bootloader? I think he need DEV options and OEM unlock enabled, right?
Consider: There is no MIUI on the phone, its a Android One Phone.

You are right, I forgot about OEM unlock option (I enable it by default for all my devices). In this case, data should be safe.
My phone is unlocked but OEM Unlock was disabled in Developer Options... So I think is not a problem having that option disabled.

Try to erase using 'Google Find My Device' i think you can erase the phone using that, also you can know locations where the Device right now.
Just try, Good Luck :good:
Hit 'Thanks' if helped. ASAP
I am fairly certain there would be ways to circumvent the google account verification using fastboot commands and MiFlash. It takes some work and patience, but it should work.
However, as far as I know there are ways to get the IMEIs of the device blocked by carriers when reporting the device stolen. Not entirley sure what needs to be done to do this, but this would render the device useless for the thief.

Imei blocking is not really gonna help. It's too easy to change.
Yes there are ways around everything in this thread and tuts to do it are only a search away. Heck we host most of the tutorials right here.
Trying to help out a family member. She setup a pattern on her phone and forgot it....
Google search returns "dr.fone" but when installed it only shows options till GS3 IIRC
Samsung find my mobile doesn't help as location is off
She has no backup and doesn't sync with Google Photos.
Any idea how to remove the pattern and retain the data?
if you set pattern only to unlock the phone then there is no chance you forget pattern i am using finger,pattern & iris to unlock my S8+ there is no way to unlock your phone without correct pattern factory reset is only option to unlock if FRP ia not On

i've read that there is a way to sideload other firmware, like in videos such as below (xda wont let me post video because i'm new), but search for "ALL SAMSUNG WITHOUT DATA LOST Remove Pin,Pattern,Password In FRP ON,OEM Mode Part 2 to Part 18"
anyone know how to do this for s8+ ?
I set a pattern and don't remember it, battery died so I couldn't use my fingerprint. phone is NOT attached to samsung account, so I am really in a bind here because I need to access it withOUT wiping
Please help
Hi Guys,
I have a couple T580 tablets for my kids, and we had just gotten a new one for Christmas that I set up. I THOUGHT I had done everything correctly, but the new tablet is giving me the FRP Lock suddenly.
Any idea how that could happen? Is there any way to recover the tablet or do I have to do a original rom flash?
Thanks

Somethings not right. You don't "suddenly get an FRP lock". An FRP lock occurs only after you "factory reset" the tablet and don't know the google account login. And that is only if you hadn't enabled "OEM" in "Developer options". What makes you think it is the "FRP lock"? And if it is locked, flashing a ROM with Odin won't help. You'll still need the google account info to access the tablet.

Because this is what it says when I start the tablet...

I have a google account, and info, for the tablet. Not sure how I put it in when the boot process is blocked though...
My only thought is something happened with Magisk?

Again, unless something has changed, which I doubt, that is not the way the FRP lock works. First of all, you said nothing about having a custom ROM installed. But even if you did, the FRP lock would NOT prevent the tablet from booting. It would merely ask for your google account info when it did boot. Have you tried booting into recovery and performing a factory reset?
edit: Let me explain what FRP means. In early versions of Android, if your phone/tablet were lost or stolen, anyone could bypass your "screen lock" simply by booting into recovery mode and perfoming a Factory Reset. So Google came up with the Factory Reset Prevention lock. So if someone tried to use the Factory Reset, the lock would demand the google account login and password to access the tablet. So if you wanted to sell your tablet, you either had to enable "Developer options" and then use that to "Enable OEM", prior to reseting the tablet or put in a google account whose info you could pass to the buyer, remove your real account, and then reset.
In any case, the tablet did NOT show the message you are getting. I've bought several T580s on eBay that WERE locked, and none of them gave that message. A locked tablet would still let you install stock ROMs with Odin, but the tablet would still ask for the google account info. But the way around that can be found in this forum.

I dont think I do, its stock rom, but Magisk is installed which I believe is not a custom rom.

When I turn on the power, the screen comes on, and then says "Custom Binary blocked by FRP Lock" then the screen turns off. I have not tried a factory reset because I was hoping to find a solution without losing everything before I did something that could not be undone.
The only thing left is, I know samsung will (if detected) attempt to remove software. I wonder if it somehow tried to reset automatically and in so doing caused this.
A factory reset does not help in your case.
First option is: contact your person, who sell the phone. Because he must unlock this one in his Google settings.
The question is: how many times a wrong oe no account was insert, that the device doesn't start up till the possibility to insert the correct account.

You don't lose everything with a Factory Reset and what you do lose should be easily recovered from your google account backup. And nothing else could be done that wouldn't also cause a reset.

No one sold me this phone, I bought it new. There is no unlock option. The phone doesnt event start booting, the screen turns on says the FRP lock, then turns off.
Ab FRP Lock said, that the phone is looked via a Google account.
In a normal case, you can only unlock the device, if you insert the correct Account with password.
I don't know.. maybe you have insert 3 time wrong credentials... why the device give your not the possibility to unlock the device.
Try an complete wipe / factory reset out of the recovery menu, so that the OS can start.
The lock isn't away, but maybe you have the possibility to insert the correct data.
In Download Mode here is what I see:

Alright I just flashed the latest rom and that fixed it.
I now know a little bit about what is going on. When I got the tablet, I set it up for me. Then I discovered googles "family link" so I set it up again for my daughter.
Child accounts have FRP protection. I dont know what triggered it, but somehow it activated recently when it discovered magisk which I had installed some time back.
Now I am super irritated and over Family Link...
Is it poss to get passed Google Verify lock as I've got a g950f from my late mothers but don't know any of deets for log ins. Can't access setting to allow ADB either
factory reset .... but you'll lose all data .....
Factory reset doesn't remove the frp lock
Okay, we removed a frp-lock once by using Odin. The best you can do is search for the right stock Rom and flash this with Odin, but you need to access download-mode on your phone which must be possible also with a phone with frp-lock, because it is there where the frp-lock is shown. For as far as I know, also recovery-mode should normally still be available.
