Hello,
This is my first post here and I'm really desperate.
My phone has a fingerprint, face scanner, and pattern unlocks configured. On Friday I changed my pattern and as you know after 72 hours MIUI asks you to re-enter your pattern. Yesterday on Monday I tried entering it and I found out that I had forgotten the pattern I set on Friday ( I know I'm stupid for not backing up the important things I had there but I've been dealing with many personal problems and I'm currently not very stable at the moment)
I went through many threads and I didn't find a solution to remove the pattern unlock without losing my files or to at least allow me to backup some important things like the pictures and videos of my father before his death and some other important files that are currently there.
Is there any way I can disable the pattern unlock and make fingerprint unlock or the face unlock the primary unlocking methods? because these ones are also configured.
What options do I have to fix this without losing the data?
is there any way I can unlock the bootloader ,root the device and install a custom recovery without losing my data ?
I would really appreciate it so much if I can get any advice on how to proceed with this.
Thank you very much and I do apologize for my English.

So my friend put a pattern lock on my 1st gen moto g(xt-1033)(non-root) and by the time I came to realize what happened and asked him the pattern, he had forgotten the pattern crying:). We have tried several patterns but I am still locked out. I am not sure if debugging was on or not and it's not detected by any pc for some reason (I guess you have to unlock it first for the pc to detect it).
I really can't afford to do a factory reset. I need the data.
Can any dev or anyone help me unlock my phone without losing any data?
I'd really really appreciate any kind of help.
TIA.
There are many sites selling Mix 3's some Chinese, some Global, some with locked bootloaders, and some with unlocked bootloaders, this thread is to help people "protect" the devices they have bought (or will buy).
It's through my understanding that the most "secure" way of protecting your phone & data from thief's is to have your bootloader locked, with no custom recovery, encryption on & usb debugging disabled right?
This is because with a unlocked bootloader, the thief has the ability to boot into TWRP (for example) & simply wipe your pin/password/lock off the phone completely, then just boot it up, factory reset it & sell it.
I know there is methods such as putting the phone in cold temperatures so you can retrieve the encryption keys from the RAM, but assuming the thief is just basic & what's to make some quick money off your phone...So...
What's the best way & most recommended thing to do with Xiaomi devices specifically, locked/unlocked, encrypted/not-encrypted, does it matter?, If not, why not?
Any help is appreciated! The more in-depth the better.
Even with a locked bootloader a thief can hold VolUp while booting, wipe phone and sell it. Wiping is possible in any case and thats not even the issue a stolen Phone is gone.
The issue are your data which can be stolen too when you have a unlocked bootloader. Simply boot to twrp connect usb and copy everything. But you can prevent that with encryption and enable "requires pattern to start". That way if your phone gets stolen the thief can still Install/use Twrp but he needs to enter a pattern to decrypt the storage. If he doesnt, twrp wont be able to read the partition and your data is safe. He can still wipe the Phone and sell it but you cant prevent that. I don't know if the pattern generates the encryption keys or retrieves them from somewhere but i'd assume it generates them, probably together with some device specific values, else that would be a flaw in my book. If someone could enlighten me here that'd be nice.
If your bootloader is locked he also can't access your data. Since stock recovers doesn't allow/support Usb-filetransfer. So a lockpattern is all you need there. Encryption shouldnt really matter against the normal thief.
I am going this way: Unlocked bootloader to get rid of Miui, Twrp to have a proper recovery menu, and encryption+pattern to save my data. Disable USB-Developer Options to prevent adb shenanigans.
But on the hand if you wan't to get really panariod a locked bootloader would be better since you still can read the system image from the phone from twrp, this means, and this is a easy way to do it, you could read it copy it to the pc and simply brutefroce the lockpattern. If you have the partitions you can simply try 3 patterns either it works or the phone locks itself up because you did 3 wrong. If it locks up you simply write the partitions back and try again. If you can do 3 in 30 seconds you are done in 45 days since there are only 390.000 different patterns on a 3x3 grid (which is what most people use since some Roms don't even allow for 4x4 or 5x5) but if you emulate it and can do 3 in 15 seconds you are down to 23 days. If you run it in 20 emulators you are done in 1 day. (That would be an awesome weekend project.) In emulation you could really optimize this since you can cut everything out what isn't needed for the attempt to encrypt the partition. you dont even need the screen to load, simply send the decryption module whatever the last module in the Numbers-from-touches-chain would have sent, everything that is loaded before the attempt to decrypt must be unencrypted therefore can be messed with, probably it's even universal across phones since that's a stock android thing. If it tries to write used attempts, save whatever what gets overwritten beforehand, let it write its thing, kill the process, revert changes and try again with the next set. Maybe you get it down to 3s or 4s for 3 attempts and boom you are at 6 hours to encrypt any android phone, no matter which version, with an unlocked bootloader which uses a 3x3 pattern. But your data would be really valueable to someone if they did this. You can't do that with a locked bootloader since you can't read the partitions or you could just use the 5x5 pattern, which you cant do on MIUI (i just tried and havent found where you could change it). But probably i have a giant oversight in there so this probably woudn't work
________________________________________________
On the other hand if you want to recover your phone you should make it as easy as possible to get the thief into your phone since you dont want them to run it off and wipe it. I DONT RECOMMEND THIS. But you could make a 2nd user who has no lock pattern on it. Concider your Data public at this point but while they are busy looking at your selfies you could use a app like prey to track the phone. But since Data are more important than a phone i'd never do or recommend that.
Or you could just buy a tin foil hat.

Really appreciate the time you took to type out this post, thankyou.
Hello guys,
Can anyone introduce a way to unlock the pattern of Samsung a30s-fn (a307fn) with Android 10?
The bootloader is locked and the phone has a warranty.
ADB is detected on the computer and known the device, but the ADB shell does not open.
If you know the path of the pattern lock file, state the address, or if you know an other way, help meeeeee.
Certainly, your efforts are well appreciated.
I´ll be honest with you, I have no idea of how to unlock a device like that.
So if you want to use the phone, I´ll recommend you to save the important files and factory reset on recovery.
https://forum.xda-developers.com/t/remove-bypass-lockscreen-with-recovery.3530008/
This could help, but I feel you can damage your device.
If either Samsung or Google find my device junk is active I think you can use that.
This why I never password lock a phone.
You will lose access sooner or latter even though the device is right in front of you.
A hardware failure is all it takes.
Hello - I have a rather unique situation and have been searching for possible solutions since last few days. I have forgotten my pin or potentially an update or my office apps have locked my phone. I have it connected using fastboot to my PC however I am not able to flash TWRP as it gives an error: Flashing not allowed in Lock State. Is there any way for me to back up the data before doing a reset? Is there any code which can be used to bruteforce different pin combinations in recovery mode / fastboot mode? Any help is greatly appreciated. I have the output of "fastboot getvar all" in case that can help you locate the partition to boot/erase. thanks a ton!

In what way are you phone locked? I don't think there are anything you can do to save your data if you don't know your password/pin. TWRP wouldn't have helped in this case either.
Hi - thanks for your reply. My pin is not working and every pin trial is taking quite a bit of time. I am able to try pins quickly in recovery mode but trying all possible 4 digit combinations will take quite a bit of time. Alternatively, a brute force code to keep trying different pins would also be beneficial if you are aware of it.
Wont adb would have let me back up my phone data?
No way to bruteforce it that I am aware off.
your pin is needed to decrypt the encryption key that is used to decrypt data. So you can't access or backup any data without your pin. This is by design.
But cant the encryption key be overwritten using my biometrics which I have registered as well? Or something that manufacturer can do because there are tonnes of solutions for samsung and lg devices but am struggling to find something for oneplus..

Perhaps this is because OnePlus has properly secured their devices and Samsung/LG hasn't? Though I do contest that statement. By my knowledge all devices perform a data wipe when the bootloader is unlocked (aside from one OP device that had a flaw in this area IIRC).
Please view this from another perspective: if your device was stolen and you've PIN protected it, would you want the thief to be able to unlock it and view all your pictures/videos/documents/etc?

I agree but one pin cant and should not be the only way to unlock phone. In my particular case, I have now started to think that some of the app has messed up with the pin or an android update has messed up with the pin. I am quite surprised that a forgot pin / pattern option doesnt even come as if no one can forget pin. Is there a way to hack into my phone given I am logged into same gmail and other apps as I am logged into my new realme phone?

First time I've heard of a failing PIN, let alone an app that would mess with it (which is absolutely impossible). Asking for a hack into your phone is asking for an illegal way to access your device, which crosses a boundary we will not get into on this platform. We tweak devices, we add functionality, we use exploits to alter the aesthetics of a device and we surely mess them up a lot but we will not support anything beyond our terms.
But! If there indeed is an issue with the OnePlus 8T PIN security, I hope people will report it here. AFAIK there is no such issue widely known.
I also hope it's a lesson in creating proper backups. I guess learning the hard way is the best way. I think we've all been there. I sure have!
you could reset it and enter email registered with that device they fix or email you code to fix
Hello all,
Even though it is my first post, I'm an old member...
I know people is alwas asking for that answer but I need to ask it before having to reset my phone.
I've never used the pattern way of locking my phone and rather used instead password but I decided to use a pattern to lock my phone and now that I've forgotten it, I'm stuck...
My phone is on stock Rom, locked bootloader and USB debugging mode activated.
Is there any way to bypass that security and to use my phone again WITHOUT wiping anything (I'm on travel and I completely depend on my saved datas, that's why I'm looking for any way to do that) or am I just wasting my time ???
I know a lot of people will tell me that it's not possible but I'm still hoping that one will tell me it is and will give me the way to do that...
Thank you all...
