Stock rom?

yes

Any case? Did you reflash rom or just perform factory reset?

yes. i reflash . and didnt have any case

Then it looks like hardware issue unfortunately :/

Hi,
did you by any chance unlock your bootloader? I just unlocked my bootloader this morning (which also includes a factory reset) an now I cannot use my fingerprint any longer for any task (unlock phone, login into paypal etc.) The registration of the fingerprint seems to work but it is not recognised afterwards.
Update 30.05.2016:
Got my fingerprint sensor working again. The reason for not recognizing my fingerprints was the option "allow OEM unlock" enabled in the developer options. After disabling this option unlocking the phone via fingerprint is working again.

i didnt do unlcok oem .

Fingerprint sensor stopped working after flash

Hi,
I was on MM and the fingerprint sensor worked some of the time and it wasn't reliable. I decided to use FlashTool to flash the same software to have a nice clean install, however, after I did that the fingerprint sensor stopped working. Every time I try to add a fingerprint, it says put my finger on the sensor and wait for the vibration, but it never worked.
Is there something I have to tick in FlashTool? I am using the right FTF.
Edit: In Service Test > Fingerprint Sensor, it appears to be fine. Also, DRM keys are intact if that matters. I was worried I wiped too many things when I flashed the FTF.
I've also tried adding fingerprints in Safe Mode as well as flashing FTF from a different region (but for the device). I am still unable to add fingerprints
Did you unlock bootloader? I had the same issue afterwards. Fortunately got a new one now, but I'm not unlocking for the moment.

Forgotten pattern unlock, fingerprint works

I can unlock my phone OK with my fingerprint, but I can't remember my pattern unlock (well, I think I can, but the phone doesn't accept it). I need the pattern to modify the fingerprint unlock, e.g. to add more fingers. Anyone know how to reset the pattern when fingerprint is working OK?
I'm on stock .253.

Thanks. I think this would have worked, or I could have used myxperia.sonymobile.com similarly. Unfortunately I rebooted the phone, and it turns out, even with fingerprint enabled, that it needs a pattern to unlock the first time after rebooting! I had to wipe it with Xperia Companion (there seems to be no on-device recovery user interface that we can use), which was annoying.
I've now set it up again and made very sure I knew the pattern before adding fingerprints!

[For newbie] FRP and Phone lock / unlocked explanation

Hi people!
I know, I'm completely newbie in this.
But I'm getting in trouble and confused about it.
The question is simple:
What's means FRP lock / unlocked and Phone lock / unlocked?
And what's the difference between them?
FRP means Factory Reset Protection. If locked your phone will be protected of unauthorized factory​ resets. If a stranger tries to reset your phone, the phone will ask for your Google password on startup.
So if you unlock FRP you will lose that protection but this is required too unlock your bootloader (that's what you called phone locked/unlocked).
Phone locked (bootloader locked) means that you cannot make any changes too the partitions of your phone for example the recovery. So you are required to unlock your phone to install custom recoveries and ROMs like TWRP or RR etc.
Hope I could help you clear some things up.
If you're planning to sell your Android phone, make sure to remove your Google account from it first or else the next owner wouldn't be able to use it.
FRP means Factory Reset Protection. If locked your phone will be protected of unauthorized factory​ resets. If a stranger tries to reset your phone, the phone will ask for your Google password on startup.

actory Reset Protection (FRP) is a security method that was designed to make sure someone can't just wipe and factory reset your phone if you've lost it or it was stolen. Starting with Android Lollipop, FRP is "standard" in vanilla Android, and most companies making our phones have implemented it in their own models.Mar 29, 2016

Hi everybody,
My question is going to sound stupid, but now that I've got the unlock code for the bootloader, how do I unlock the FRP?
It is to this part that I am lost.
Sorry but I'm not very young anymore and not healthy. I had a big car accident and am much more on my phone and my computer

You need have enabled OEM unlock in Developer options for unlock FRP

Hi,
OK so I activate the OEM to unlock the FRP.
And for unlocking the Bootloader I can use Huawei Multi Tools?
Should I delete my Google Account or Huawei before doing these manipulations?
I do not have fingerprint or pattern lock.
Thanks in advance for your answers.

I unlocked the bootloader. Done on the instructions of the website:https://emui.huawei.com/en/plugin/unlock/step. After unlocking bootloader on my phone fastboot appeared the inscription "PHONE Unlock" and "Unlock FPR". On my device sprosili settings. After that, I re-entered entered the Google account, but the phone then began to hang periodically. I went into developer mode, done a factory reset there. And decided to turn back. Went to fastboot, blocked Downloader. Phone rebooted, then on the screen appeared the inscription: "Relock PHONE" and "FPR Lock". Out of fastboot, there was a black window where it says to restore the system through recovery in the air, but when I try to do fails. Help me, please!

Tab S6: Factory Reset with Stock ROM and still getting "protected by Knox Cloud Service"

Recently purchased a used Galaxy Tab S6. I was warned it had a warning about the bootloader being unlocked. No big deal. The seller couldn't remember his Samsung account credentials so we couldn't factory reset at time of purchase via Settings. No big deal. I went into Download Mode and relocked the bootloader. I went into Recovery Mode and Factory Reset.
Then I ran into "This tablet is protected by Know Cloud Service. To continue setup, connect to a wi-fi or mobile network." I've done that (since I can't skip the step) and get the dreaded "Can't create work profile" error and that's as far as the set up will go.
So I used Odin to flash the latest stock ROM and factory reset again and wiped the cache and I'm still having that problem.
In download mode, I've confirmed that Knox has been tripped.
I've googled like mad and I'm not finding a solution. Can anyone help me out? I'd prefer to stay on Stock ROM so there are no hardware issues (particularly with the SPen) as I'm planning to use this device extensively for note-taking (with OneNote). However, I'm open to custom ROM if that's my best/easiest/simplest route.
Thanks in advance!
If you're able, unlock the bootloader again. When you flashed with Odin, did you use the CSC or HOME_CSC file?

I used CSC. As I understand it, that is the "deeper" reset option.

Correct, that wipes user data.
Unlock the bootloader again, which will wipe the device (again), and see if it's removed the FRP. If not, you should be able to flash TWRP, from which you should be able to flash this to disable the FRP.
I can't access the developer options because I can't get through the setup wizard. So I can't flip the OEM Unlocking so the download mode doesn't give me the option to unlock. I can connect to ADB via the Recovery Mode but Fastboot doesn't see it so I can't do "oem unlock." Are there any other methods to unlock it? My friend Google hasn't found any yet.
Seller was able to login to both his Google and Samsung accounts and remove the device from them. That got me through the 100% Know Enrollment Service before it hung up in the "update" portion again. He was also able to send a message to the tablet from the Samsung account to try and release it further but, of course, since I've wiped it, that message can't get through.
I'm getting desperate. I might have bought a paperweight! Any once else have a suggestion?
Checked with the seller. He bought it from Kijiji as well from the original owner. It's always been a personal device, never an institutional one.
Last night's searching of the internet determined that the device is in "prenormal" status so I'm just going to wait 7 days and reboot. That might be sufficient. Nothing to lose at this point.

Question Sm-t227u mdm lock/rooting help

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.
