Lock Pattern changed on its own, help sought as no longer able to unlock phone

Hi all,
Greetings first as this is my first post on XDA and appreciate all you guys contribution all the way through here. Back to the topic I got my X9 using in good condition unless of low remaining space yet some weeks ago during my normal use the machine suddenly froze and reboot and after that though I am able to unlock on the first boot screen, by using the same unlock pattern I cannot enter my desktop and it always tell the pattern is incorrect. Yet no matter how many trial I did it didn't force me to exponential-time-wait. I googled for some time and learnt that the same problem happened on samsung S7 and some nexus device (those HTC made ones?) So at this point I am wondering if:
- there is any chance I can unlock my phone without data loss? i tried "find your phone" on ADM yet over-riding lock screen seems no longer work;
- The machine is clean as-is from the factory without any s-on/off or unlock of bootloader; under current circumstance am I still able to install TWRP and get a back up being dumped? (seems I can dump a copy and use the pc script to look into the gesture-key, or simply delete the gesture.key from TWRP / aroma manager);
- Any other alternatives I can do? I really want to keep the data inside as there were some precious photo as well as some chat-record that is not being backup to the g-drive;
thanks in advance =)

How to keep OP3 protected from any kind of theif flashing the device

I had kept my bootloader unlocked for flashing new ROMs but unfortunately i lost it on train and now i can understand that the theif can easily flash a new rom and so i can never retrive my device as far as i understood that i have to keep my bootloader locked but this means that i have to unlock and relock my bootloader each time i want to flash a new rom so this is very problematic for losing internal data too every time.
Also i don't have a job else i would have brought a new OP3T. I hope that in future OP can introduce some hardwire based tracking for lost devices , what do you people suggest?

I suggest that if the thief is able to flash a new ROM, he will be perfectly able to open the bootloader. So I recommend that you do not worry about having the bootloader open.
As for the tracking system, I think Google has already developed certain functions aimed at this use. When I have time I will investigate about this topic and update this post.
Please, be awere.

Try Google device manager. Thats the tracking tool you searching for. ?

not a big deal to reset FRP. Samsung and LG FRP takes only few minutes to be removed with z3x box. i think even stock rom have some bugs to bypass FRP. Best way is not to loose your phone.

It won't help you now, but take a screenshot of your imei, then back it up to your photos. If your phone is lost or stolen report it and depending on what country you live in, it will be black listed. Then it won't work on any carrier, no matter which rom is flashed.

Since I had kept my bootloader unlocked I believe that can easily flash a new rom so Android device manager won't be useful at all

Ya I know that I have already submitted FIR in police with the IMEI number but I believe these days they remove all the parts and sell the parts differently so very less chance in recovery

Samsung galaxy note 5 (sm-n9200) need boot-loader unlocked failing miserably....

Good afternoon folks. Im a fairly experienced guy as far as rooting and installing custom Rom's go on Samsung Phones. In this case I have POSSIBLY, the Hong Kong version of the Samsung Galaxy Note 5 (SM-N9200) and while I was able to get a root on it with King Root..it's not my desired method. I'd really like to ROOT the phone, but I need to first unlock the BOOT-LOADER.
I've tried the CROM-APK but it won't install (I Keep getting "App not installed" every time I attempt it), and to my knowledge, I don't know of any other methods. IF anyone has a SHORT or LONG winded manner of doing this it would be appreciated. I've even tried the ONE-CLICK-ONE-TOUCH all the way around method and that was to no avail as well.
Also does anyone know if this phone is LTE Capable???? Would flashing a custom Rom give me access to that feature?
Any help would be appreciated.

OK! Update to my situation, I've managed to INSTALL CROM-Service But i can't get it to run on my phone. ALSO, there is no OEM-UNLOCK feature on my phone as well which im told can occur sometimes when the developr absolutely does not want you unlocking your boot-loader.
Is there a way around this????? How do I unlokc my bootloader without that OEM-Unlock feature.

i have the same problem

how did you do can i know

RMM Unlock by Odin Flashing Pre-Oreo Rom - SM A600A

I ended up with the A6 when my HTC One M9 battery did the thing it does and destroyed my phone. The total destruction is not solely the phone's fault... I tend to drop things and bump into stuff... so... Anyway, I did very little to no research on the phone before "purchasing" it as my once absolute obsession with flashing and rooting and all the fun tinkering had since gone the way of the "Buffalo" (although, i feel like the are still around) around the time phones kind of became as good as they really needed to get. There was very little under the hood tinkering that seemed interesting anymore. Except... the whole LineageOS wth MicroG-thing. Super-excited!!!
Anyway, if you happen to be unlucky like me before you can root, the're's this whole RMM Unlock blahblahsad thing to deal with. I waited the 168 hours , following all the instructions to a T, only to find that my developer options were exactly as they had been. OEM no where to be found. I'm impatient... this is a character flaw. so, I get the whole get over it and try it again. And if there are no other options, I will, of course. But I was just looking at a similar issue just concerning a Galaxy S8+ [GUIDE] How to skip RMM STATE: PRENORMAL and install TWRP
So, like the post instructs, would it be possible on the lovley A6 to downgrade to a pre-Oreo Rom flashed via Odin in order to RMM Unlock the thing and carry on with the RMM State Bypass Mesa and No Verify Opt Encrypt. Or am I getting something completely wrong here?
I guess maybe one is never really over flashing rom and rooting devices. but i dig it!
Any help would be much appreciated. Thanks XDA gang.

So what I understand is that you want... root on Pie... right?

Sorry to say, but ... why is she not able to remember the password she had set previously
If her Google account is not linked to screen locking, maybe it is possible to flash a new firmware. But that would not erase the unlock password. A factory reset would do, but also wiping her data.
Best to make your mother a good coffee or tea, and she might remember the password. Then enter every possible variant and combination.
