T550 - Passcode Lock / MDM Won't allow reset - Samsung Galaxy Tab A series Questions & Answers

Hey All
Was looking for some help. I have a Galaxy sm-t550 with a passcode lock. I am unable to do a hard reset (holding down power + volume up + home button) because this device has been locked to an MDM, so that option is out.
I have successfully flashed the stock firmware using Odin downloaded from SamMobile. The issue is that is hasn't erased the user data and I'm back where I started. The only file contained in the download was the AP file (No BL or CSC). Is there a way to flash with Odin using this file to completely erase the old user data? Maybe it's simple but couldn't find this exact situation on the forum.
Thanks!

Current firmware build and why does it have an mdm in the first place?

It's through my company that uses an MDM. User forgot passcode and it's not connect to WiFi so can't sync remotely.
Current build is 6.0. Just flashing to 7.0.1 T550XXU1CQJ6

Ok. Well, I flashed to T550XXU1CQJ6 but I can always flash back to 6.0.1.
Do you know of any solutions?

Install the combination firmware then factory reset from settings. Hopefully it should wipe mdm.
Enable OEM unlock also in developer settings if it's available.

I'm in the same boat. Son bought a tablet on Offerup. Dude quickly removed his seller profile. Son didn't even test to see if the device was locked as the buyer quote on quote told him "That the device was just dead and needed a charge." Device can't be factory reset due to MDM lock.
No idea what the password may be.
Unable to reach encryption settings to force the device to wipe itself due to a password..
Feels like he just bought a really expensive paperweight. Mind helping? I'll post any other information that is needed.

Have You fixed it yet?
I'd say pop a sim card in and sync it with the mdm database
Cannot find a way to do it otherwise,

Update : Possible to enable OEM Lock via ODIN or ADB ?

# Update ##
USB Debug works great
Possible to enable OEM Lock via ODIN or ADB ?
Everything is blocked by FRP Lock
######
Hi all,
Regarding s6 edge plus, I have a SM-G928I, is it possible to enable usb debugging without going into developer options ? A friend bought a second hand phone and its locked to an account unfortunately, and ODIN wont connect so ican root/reflash due to im assuming the usb debugging not being enabled.
I'm trying to save him some money by paying a repair shop >.< any tips?
Thanks
Anyone?
They sure are nice phones, the screen real estate vs my HTC one m9 is certainly noticeable
Did you install Samsung USB drivers and plugged phone in download mode? Can try also going to recovery and performing factory reset
Have installed samsung drivers, i can see the phone on the PC as a drive to load data to, but odin doesn't see it.
Factory reset seems to still have the account linked, a security feature of 5.1 i'm sure.
I'm getting a copy of the stock rom from sammobile
http://www.sammobile.com/firmwares/database/SM-G928I/
fingers crossed i can use this and it recognises it if i just replace the stock file
can it be forced via adb?
Okay so turns out i'm thinking of the wrong thing. USB Debug works., great can interface via ODIN and ADB.
Is it possible to enable "OEM Unlock' via command line interface of adb, or ODIN ? without access to the OS this is making life hard
Flash stock firmware. You need to flash stock firmware to access the OS and then enable OEM Unlock. There is no other way. You cannot charge it even without enabling it.
AFTER ROOTING MAKE SURE NOT TO DISABLE OEM UNLOCK.
I tried that, flashed stock firmware from sammob but it still wants the sellers Gmail account has he bought a brick?
Do a factory reset after ODIN flash. Flash TWRP, access recovery, format system, cache and data (including internal) and then check.
thanks, will update soon
Stock firmware flash works
Factory reset / cache clear works
Flashing TWRP fails due to FRP lock , due to the OEM Unlock not being enabled im assuming
"Custom Binary(RECOVERY) Blocked by FRP Lock"
I'm sorry but I think you are locked out of the phone.
It certainly seems that way. its always frustrating as a geek to be defeated

Hi, I've bought a phone with same condition.
Have you solved the problem?
Sure have, I obtained a file which allows you into the settings from the Google lock screen which allows you to enable OEM unlock. Due to the legalities though I'm not sure it's allowed to share this here though
can you please post/send me this file ? and instructions, i assume you flash it via Odin/adb

Sm-T580 FRP lock and custom binary blocked by frp. Cant flash twrp recovery.

So im trying to install twrp recovery but when i try to flash it thru odin, i get a Custom Binary (RECOVERY) blocked by FRP lock. I cant factory reset because it also disabled by FRP. I cant verify the tablet because i dont know the account information as the tablet was bought through craigslist. I have tried flashing a stock firmware version and that installed fine, but i still couldnt get past the verify screen. So thats when i decided to try and flash twrp but came into the binary error. I have been trying for the past two days to find a way around the verify identity and the frp lock. I cant enable oem unlock. I have tried rootjunky method but OTG flash wont pull up the file manager when plugged into the tablet. I cant use adb because i cant enable the developer settings because you guessed it i cant get past verify identity screen. Any help would be greatly appreciated.
Sounds like you need to find the Combination Firmware.

I already tried that method but didn't work. It's on android 7.0. I tried downgrading to sm-t580.. XAR firmware 6.1 and it worked but when it boots it goes straight to a black screen asking for a password. I tried the frp call method as well but it doesnt have wifi calling.

It only works with certain versions of 6. The one ending is PL4 is the one you want. The trick is in adding the fake wifi network instead of connecting to your home network. Pay close attention to the beginning of the video.

Okay thank you. I will try that again when I get home. And this works on version 7.0? The device is currently on 7.0 but when I tried the pl4 md5 it flashes it but when I boot up the device it just goes to a black screen and asks for a password. It doesn't start at the setup wizard

You have to use Odin to install PL4. You can't flash it via TWRP. Also, make sure you wipe everything first.

I know. I can't install twrp like I said. I've been using Odin to flash everything. But when I flashed the pl4 file and tablet goes to reboot. It doesn't load the setup wizard. Doesn't show the welcome screen and pick a language. It goes straight to a black screen and asks for a password. Doesn't ask for an email or anything.

Yea but when I try to factory wipe it says mdm doesn't allow factory reset and reboots and takes me back to that same black screen. I can only wipe cache partition. I will post a picture of the screen when I get home.

Tried this as well. I did it about 20 times before giving up. I might try it again and do it about 30 to 50 times. If I was just able to get to settings I'd be straight but I can't get to the settings so that's why I'm trying to reset it as a completely new device. Do you know if I could flash the 7 inch tab A firmware onto the smt580? Or flash the smt585 firmware onto the t580 and flash the BL AP and CSC?

From what I've read, Airwatch MDM lock can't be removed by flashing ANYTHING. It is third party anti-theft protection that has nothing to do with what ROM is installed. I know I ran into their stuff a few years ago with a used laptop I bought and only Airwatch was able to solve the problem after contacting their customer and verifying the laptop wasn't stolen.

I did end up finding this. Seems the device is completely locked with no way to get around. When i flashed the device i may have deleted the admin privilages so there is no way of gettting around it as of now. I might end up paying someone to fix it or get around it or i wasted 180$ on a locked device. The guy i bought it from either blocked my number or deactivated his number as i cant get in contact with him. Pretty pissed. Thanks for all the help tho
I had the black screen password happen to me when I downgraded my SM-P580 from Android 7 to 6. Try clearing the cache. If that doesn't work, try reflashing, then turn it off and reboot to recovery and clear the cache.

Do you think if i changed the CSC to a different region on the tablet, and put a unlocked bootloader on it, would it might get rid of the frp lock? Do you happen to have a smt580? If so do you think there is anyother way of getting around this? say if i flashed like your firmware on to my tablet? Im desperate to get this thing unlocked as i would be out 180$ :crying:. Thanks for all your help so far. I really appreciate it man. Thanks to everyone who has helped so far.
Or what if i downgrade it to 6.1 and then downgrade it again to a even farther back version? Do you think this might work and gett me around the black screen? If so then i would be able to bypass the google verify account. Ima go ahead and try it unless its a risk of bricking the tablet completely.
I also read somewhere that if i flash the cp part on odin that it will erase all data. Think that might be worth a shot? But what do i need to insert in the cp slott? I know BL goes to BL and AP to AP and CSC home goes in CSC. So what goes in the cp slot?
EDIT: So instead of putting csc home in the csc slot i put the other csc file in its place. I checked the re partition box. When i did this i got a new message on the tablet in the top left of tthe download mode that says FRP is enabled, ignore PIT download. Any idea what this means?

How to recover Galaxy Tab A 10.1 (2016) without factory reset?

Hello, I need to access Galaxy Tab SM-P585 which belonged to a friend who has passed away, so pattern, pin and Google account info are unknown. Also firmware is original from Samsung, developer mode is disabled and OEM locked. The only options available are recovery mode, where I can do a factory reset or enter sideload mode, and download mode. I have found this guide https://forum.xda-developers.com/showthread.php?p=49666433 to bypass pattern but custom recovery is needed to use either Pattern Password Disable or Aroma File Manager methods. Then I have tried to install TWRP via this guide https://forum.xda-developers.com/ga...covery-official-twrp-galaxy-tab-10-1-t3473023 via Odin however device returns error "Blocked by FRP Lock" which from my search is either Google or Samsung https://www.samsung.com/us/support/frp/ Is there a way to access this device without factory reset?

Try and reflash it using Odin with a stock firmware, that might work. Get your firmware from Sam Mobile firmwares. Just make sure you get the exact corresponding firmware...

Thanks, I've looked up for SM-P585 model but found only firmwares for ME and Africa. Tried with South African version but got SECURE CHECK FAILED (BOOTLOADER) error, which I believe is because it is not exactly the same version. From the recovery menu I've found out that I need 7.0/NRD90M/T585XXU2BRB2 version (multi region) so now downloading from samsunggalaxyrom and getdroidtips. I'll see how it goes with either one...
P.S. From the instructions "Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data." so I'll use HOME_CSC_ file to keep apps and the data.

If you use CSC it will wipe the device along with any security measures set up and basically put the device back to factory setup.

Unfortunately HOME_CSC didn't work, security settings were still there, so I have applied CSC. However now FRP requires me to logon using original Google account, even after factory reset, so this functionally means that device is only for a dumpster?

Bricked Phone - Failed to mount system error & FRP lock.

Hi all 0/
I'm creating this post because well I have a bricked phone (I know, another bricked phone thread) and am asking if anybody can help or point me in the directions of help.
P
The Problem
So my phone failed to install the latest security update that was released in September; just gave me the update failed error on reboot. I ignored this for a month as it didn't bother me but it started to get progressively more buggy, random crashes then random restarts then google play services just stopped working. This point I looked into it and the internet told me to use smartswitch to apply the update (which I assumed to be the problem at the time). Smartswitch couldn't update it which through it into emergency recovery mode. Smartswitch was then blocked by FRP lock when I tried to use emergency recovery mode.
I then tried by use Odin to flash stock firmware, which FRP lock blocked. Now i'm stuck as I can't flash anything with odin or use smartswitch so am stuck with either download mode of emergency recovery page.
I have extracted and reflashed all the sys.img flash expect system which has allowed me to boot to recovery but have the error
DM verity failed
E/ failed to mount system (invalid argument)
All the fixes for dm verity failed system, frp lock etc don't work as i think i have a combination of problems
Neither have I found a post that describes this problem anywhere
Thank you very much for reading

The fpr lock isn't supposed to block you from installing official factory firmware. But it has to be the exact firmware. It should install and then ask for your gmail

That's what I thought, but when I've tried to use smart switch it blocks me, and every version of firmware I've found with odin it blocks. How can I find out which firmware my phone was on before it bricked its self? or do you think its a case of trying many?
assuming smartswitch is unable to find the firmware that i need is there any way of telling it which version to flash?

Smartswitch can't flash it because whatever crapped out changed the device ID or some info it looks to for authentication. I had that happen once. After a fw flash my phone changed from SM-G928W8 to G928F and smart switch wouldn't touch it. So what I had to do was find the exact match, you need to know what carrier your phone came from to get the model for firmware, like t mobile or Verizon, and then get that version, I think nougat or mm would work but our device shipped with mm. Odin will work but it the fw has to match the device. Then once it boots your gmail info is needed.

Okay I think I understand, so i need the exact firmware it was on before it crapped out, otherwise it will think i'm trying to flash new firmware an frp lock stops it right? My phone came unlocked in the UK., will i just have to try many different versions in hope one works?
Noob question, what does fw flash stand for?
Thanks so much for answering my questions : )

Help with NFC Crashing - AT&T S8 Active

Hey,
Need some help. My brand new AT&T S8 Active arrived yesterday. Since I am located outside the US I'm stuck with utilising Odin to update the software.
The current version listed on the AT&T website was 5CSK1 and I was able to track down the update:
https://forum.xda-developers.com/showpost.php?p=81251867&postcount=743
It installed successfully, everything is going well however I am unable turn on NFC. The toggle found in the settings menu is off and when I attempt to switch it on it greys out for a few seconds then the 'NFC keeps stopping' error appears on the bottom of the screen.
I've cleared the cache/data for the NFC app - no luck,
I've performed a factory reset via recovery menu - no luck.
I've installed the previous build 5CSJ3 from: https://forum.xda-developers.com/showpost.php?p=80903399&postcount=187 with a factory reset straight after - no luck.
I'm currently back on the latest K1 build.
Logcat shows errors with 'libnfc_nci' and a 'Fatal Exception' for the 'com.android.nfc' process. And to top it all off the NFC app is draining my battery.
If anyone can help me that would be awesome.

ugh, the active line... there hasnt ever been much support for those. All you can really do is keep flashing the stock firmware and hope that the errors resolve themselves.
Side note: have you noticed how they stopped making the active phones? They were a dismal failure. All they are is the regular phone in a case that you cant take off :/

I've installed the previous build 5CSJ3 from: https://forum.xda-developers.com/showpost.php?p=80903399&postcount=187 with a factory reset straight after - no luck.
I'm currently back on the latest K1 build.
Logcat shows errors with 'libnfc_nci' and a 'Fatal Exception' for the 'com.android.nfc' process. And to top it all off the NFC app is draining my battery.
If anyone can help me that would be awesome.

Might try redownloading a different firmware from a differ location. I had this issue on a lg back in the day the camera wouldnt work no matter what I always restored stock with one firm I had. And it ended up being a bad download. Another possibility is a bad NFC chip. If it's new I'd have it warranted
Thankyou, Thankyou Youdoofus and TheMadScientist for your advice.
Woke up early today (3am) with coffee in hand I tried again downloading the K1 and J3 builds; neither worked.
Unfortunately there's no alternative download for them... Google points to the XDA forums which seem to come from some Russian forum.
I've gone to an earlier build - 5CSI3 - https://forum.xda-developers.com/showpost.php?p=80505887&postcount=186 which works.
So it's not a NFC chip issue, yay. Now, just need to figure out what I'll do when the next update hits at the end of this month.

Yeah, it's working on the 5CSI3 build from October 2019, there's been two recent updates since then (and another will come at the end of the month). I don't know what's happening as no one else has reported this issue .
Just wanting to be on the most recent version for security and the annoyance of having data wiped every update.
Edit: Yeah, Odin v3.13.1 . No errors being displayed, all green.
This issue is very likely to be caused by 3rd party sim unlock or FRP removal and meddling with knox.
I have been trying to get around this problem and it seems it is either a security measure to disable nfc payments on triggering knoxguard or problem with modem.
this problem started after CSJ3 update afaik and only on some phones, if someone can explain this would be great.
Solution:
You will lose all data so backup is recommended
Remove your SIM card, re-install the firmware with ODIN and check Nand Erase auto reboot and F. reset time
Check your KG status(checking or prenormal) on the bootloader, and in settings>device care you will see Security is disabled and it crashes when you click it.
I also noticed the settings menu is weird with many broken options and dailer codes dont work anymore.
EDIT: Workaround Solution:
THIS IS FOR G892A ONLY who have problem with NFC after updating to builds after December 2019
Disclaimer: do at your own risk and can break your phone signal or system detected as rooted/custom
note: you will lose all data, ONLY check "Auto Reboot" and "F. Reset Time" in odin
1) Backup your data
2) Delete your google account, so FRP : OFF in bootloader (this can cause problems if not done)
3) Flash 5 firmware files G892AUCS5CTC1 (latest rom with march 2020 security) and get back to bootloader
4) Flash 3 files from G892AUCS5CSI3 : BL, CP and CSC
(odin will say PASS, but recovery will give error)
5) select wipe data partition then reboot to system
when the phone starts you will see NFC logo in statusbar means you are successful
if you get errors while using odin: flash combination file : G892AUCU5ASD1 if this doesnt work it means you have different problem (cable, socket, pc, bad chip)
i tried flashing CP file only and phone booted into UPLOAD mode, so dont panic if you get into UPLOAD mode just reboot with 3 buttons to recovery and start over

Hello There!..kind of new about this so..long story short..
Phone had Android 8, and I really love Night mode on Android 9, so...I've found BL, AP, CP, CSC, USER Data ROM for GALAXY S8 ACTIVE AT&T Unlocked, however..I am a little bit afraid of any NAND Erase.
I am not an expert, but I can tell you are. By any chance do you have any vide or graphic tutorial abot how you can perform these actions? It is very odd that I am unable to have any *# codes working, and lately, I've received this odd message about NFC Service has stopped, so...any graphic step by step guide will be highly appreciated it.
I've tried ....soft reset, then factory reset, then flash again ODIN (BL, AP,CP, CSC and USER DATA ) But I have no idea how to back up my data, and it will be very helpful to have G892AUCS5CSI3 as well.
Thank you very much for your time, I hope you can help me and I appreciate very much your time.
The one that I have is AP_G892AUCS5CTC1_CL16888298_QB29841048_REV00_user_low_ship_MULTI_CERT_meta_OS9.tar
BL_G892AUCS5CTC1_CL16888298_QB29841048_REV00_user_low_ship_MULTI_CERT.tar

CSC_ATT_G892AATT5CTC1_CL16888298_QB29841048_REV00_user_low_ship_MULTI_CERT.tar
USERDATA_G892AUCS5CTC1_CL16888298_QB29841048_REV00_user_low_ship_MULTI_CERT.tar
SOLVED!
So...I've followed the steps to install only BL, CP and CSC using G892AUCS5CSI3...however, the system started as usual, and actually did not work =(
RESOLUTION:
INSTALL THE FULL G892AUCS5CSI3. Worked as magic =)
thank you for the thread!!

You can backup your data with Samsung backup and restore to Samsung cloud or to your PC with Samsung's Smart Switch app.
As for tutorial I'll try to make one with images for the latest ROM G892AUCU5CTF4 dated 20-Aug-2020 with August security patch. I'll upload it later as I still have to backup my phone before updating.
Thanks!
Thank you so much!
Is it G892AUCU5CTF4 a estable versión for S8 Active? Or does it has any other bugs? I had to "downgrade" and now things are pretty cool, however, I would love to have the newest version. Thank you!

It doesn't have any bugs but some people have issue with flashing new builds, if you have this issue just install CSI3 build or earlier

Same. I also tried CTA2 and CTL1. Everything after CSI3 has NFC crashing and excessive battery drain. I've tried multiple flashes on multiple phones.

This did not work for me, not even with "Nand Erase" checked.

Same. The problem of the secret dialer codes not working parallels the NFC problem for me; that is to say that it doesn't work on any firmware after CSI3.

Same. I'm not sure where I originally got it from, but here's a reupload from my archives. I created a list of MD5 checksums if you care to check the five files for corruption.
