** PLEASE UNDERSTAND -- I'M LOOKING TO PRESERVE THE DATA, NOT RESET THE PHONE AND ERASE EVERYTHING**
My daughter, unexpectedly, passed away last month and I just received the phone from the investigators. I didn't know her PIN but want to preserve any data.
My daughter's phone displays "Your phone is encrypted for security. To start up your device, enter your PIN." A number of attempts at the PIN has left me with 3 attempts before it resets to factory default settings.
When I contacted AT&T for help, they directed me to Samsung. The Samsung technician directed me to a YouTube video that claims to download the data, perform a factory reset and then restores the data. It seems very sketchy to me and would rather talk to the experts here.
I have rooted phones in the past but it's been 4+ years. I am very cautious about trying anything that would jeopardize losing the data for good.
I have seen one video that demonstrates unlocking the PIN by installing TWRP, browsing with the File Manager to /data/system/ and renaming whichever file is associated with the PIN (ie. gatekeeper.password.key, gatekeeper.pattern.key, etc.). I don't know how to install TWRP if her phone doesn't have USB Debugging enabled. She and I have identical phones so I am willing to try anything on my phone prior to trying it on her phone.
** NOTE ** Through some trickery of swapping SIM cards, I was able to reset her Google password having Google text a code which has to be entered in order to set a new password.
Like the title says, my father just passed and we're locked out of his phone.
Don't want to factory reset the phone because all of his accounts are on there in apps and we're not able to figure out if we missed anything. Worried about upcoming bills and then any stocks or trades he did only in apps.
Currently the phone is requiring a pattern unlock and I've unsuccessfully been able to guess it so it kind of locked us out of doing anything. Can't even power off or reset it.
It's also saying "unlock the phone to use fingerprints." Does that mean even if we were to somehow guess the pattern would we still need the fingerprint to open the phone?
Is there a way we can bypass any of this? I looked into some programs and downloaded them but they all said they would erase the data if we removed the pattern unlock.
I have access to his Gmail via a tablet that we knew the pin code for but haven't been able to reset the password just yet. Not sure if having the google account password available will help us unlock the phone or not?
Any help or links to tutorials would greatly be appreciated.
By sheer luck I was able to guess the swipe unlock pattern so the phone is now unlocked for me. Mods can delete this thread if they want.
Hi All,
Purchased what was advertised as a G8X unlocked for ATT, turns out its Sprint, and is Google FRP locked to a previous user. I try to do a factory reset and it says cannot unmount system partition at /mnt/system and say can't open /cache/recovery/log: Permission denied.
The phone is physically super clean, seems unused even. Any way to get past the Google FRP lock, or use any of the choices from the Android Recovery menu to update from SD card, for instance. I'm going to use it on a MVNO, such as Mint or Red Pcoket or H2O or something, so I have some flexibility there. I just don';t want to have to do a return if there is an easy way to get it to either load a new ROM or whatever.
I've used ADB some years ago , but would need to read a full guide, as I don't remember anything. I run linux on my PC's at home, have for years, so the file system seems familiar, etc.
Let me know if there is a super easy way to 1. Remove Google FRP lock or 2. Load a new ROM /Root this thing to get past the FRP lock and be able to use this phone without sending it back.
Thanks in advance.
You can try using the FireHose hack in order to unlock the bootloader, flash TWRP, and replace the various partitions with clean ones. Not sure how effective this would be, but give it a try.

Hello! So I am on a journey to attempt to root a Samsung tab a7 lite sm-t227u. So I want to be extremely transparent as to my reason for rooting:
I was given this tablet by my father whom got it from a previous job. When he left the job they never asked for it back, a long with a good bit of supplies he had that he got to keep.
So, I have this tablet, I can get into it as it doesn't have a passcode. I have wiped it by factory reset as well. However, it has IBM's MAAS360 installed and after factory reset AND a firmware flash using odin I still cannot get rid of this maas360 mdm. It is not Knox locked. I can activate developer mode and change all those settings, but I cannot download any apps through the app store at all or enable unknown source app install as those are under an IT block. I also do not have the OEM unlock option in dev options. I've tried the whole changing the date and connecting to wifi, with and without sim card but I cannot get this option to show, nor can I unlock the bootload through fastboot.
I have read that most of the new samsung phones do not have a bootloader unlock option, but from what I can tell that is specific to the snapdragon phones, and this tablet is running a mediatek chip.
Now, if I can remove mdm restrictions without rooting that's great, but I have a feeling that is the only way to properly flash this thing to completely remove the mdm.
I have tried the recovery tar that is posted in this forum but I cannot get it to flash, likely because I still don't have an unlocked bootloader
Have any of you all faced something similar or know of a solution? I may call the company the mdm is managed by and just see if they will remove it from their system, but I find it highly unlikely.
SM-T227U is an American model wich doesn't have the OEM unlocking option, you could unlock using unofficial ways but those are not pretty "stable".

Hey man! Still got your tab 7? I also have a SM-T227U and have oem unlocked! After doing the usual stuff, you will want to turn off automatically update in developer settings. After that, go to settings>General management>Date and time and select manual time and date, and set it for exactly 10 days before the day you attempt this. OEM unlock will appear in dev settings!!!
Then turn off device and while holding power up + power down, plug into PC. It will show the pre-download mode screen where it asks if you want to continue. Just follow the on screen instructions to unlock bootloader!
*note that the bootloader unlocking results in an unavoidable factory reset**

Sweet! I will absolutely try this when I get home this afternoon, will report back with results!
But just for clarity. Let's say I start with a freshly wiped tablet. Go through set up and connect to wifi, do I need to add a Google and Samsung account? Then in dev settings, enable USB debugging, also enable wifi debugging? Then change the date. Is there any step I am missing?

If it has Mediatek chipset then you can use SP flash tool to format the tablet firmware and reflash it.
I would strongly recommend you to backup the NV DATA and NVRAM files before you format the tablet.

You can follow this guide actually! ( https://forum.xda-developers.com/t/...220-t225-install-lsposed-magisk-mods.4406933/) it recommends just skipping the setup junk
I have found that many times, rooting methods work across different models of the same device unless there are some sort of major differences in chipsets or some sort of random change lol
The only thing that doesn't seem to work for our model is section V of the guide which is for the removal of the "bootloader is unlocked" screen at startup. so you will still need to press the power button on that screen to boot up. It's a tiny hassle, but otherwise no big deal in my personal opinion
Make sure to read all the way to the end of the root section (section 4) and especially remember step 7. I retried probably 4 times and even patched the entire AP file of the firmware for use in odin (doing this gives a second warning on Knox screen that it isn't samsung official fw then boots normally into the bootlogo screen) before realizing everything was going fine.. I recommend just using the patched Magisk boot.img first just because I find it unsightly
Just flash the boot.tar in the AP slot. Don't download any of the boot imgs from the guide because they are for the t220's and t225's. I'll link the one I made according to the guide below. It'll save you some time and you won't need to install zarchiver and Magick just to have it factory reset again lol. Just download the latest Magisk apk (26.1) from the official github (https://github.com/topjohnwu/Magisk/releases) and install it when you have completed the 2nd factory reset/the patched boot img install.
