Dreaded MDM does not allow factory reset!!! - General Questions and Answers

Wanted to start a new thread on this subject, as I know that there is plenty on it within this site. I have perhaps unique problem with this however. I have a T810 stuck in bootloop and can not get to any UI. I can access recovery and boot loader, but USB debugging is not enabled. I am fairly versed in recovering devices, so I am open to any suggestions.
Where to begin? Suggestions?

Day 2 of this project:
I started with 6.0.1 stock ROM flash as I could not complete a data factory wipe. Stuck in bootloop...
Downgraded to stock 5.1.1... new boot up, but still looping only this time it is cutting off and on.
Then tried changing ROM CSC version from XAR (US) to XAC (Canada) b/c I thought that I had a Canadian version... still looping
I was able to install TWRP 3.1.0 however, thought not sure what I can do with this from here.
Maybe try custom ROM and root from TWRP?

UPDATE: TWRP factory data wipe cleared the issue!!!

Hello everyone, I was given a Samsung Galaxy A5 SM-A500FU, and I have the same problem,
I can not do the hard reset because of the MDM does not allow factoryReset. The phone will restart automatically.
I can not update via Odin because of the MDM.
How do I remove or exceed MDM to reset and update the firmware?
Thank you.

[Q] GT-I9502 Messed it up.. HELP!

Hi,
Being a newbie to this flashing thing. I rooted/SUsered and I had Google Apps running ok on 4.2.2 Android happily on this GT-i9502 from China...
Then I decided to try and update to 4.3. Dumb.
It's current state is: If I try to re install 4.3 latest factory stock in Odin 3.07 it fails at SYSTEM bit. then I have to put CWM back onto it to get it to do anything again (It goes into that yellow triangle screen only.)
I've tried wiping cache etc. But still no joy with Firmware restore from PC - Odin. I'm now in a cycle of Fail firmware restore then CWM to un-Brick it slightly… I can get into CWM but normal start up is just the China UNICOM splash screen then blank…
Also I might have formatted the data a few times…
I didn't do a back up of 4.2.2 either, I know I'm an idiot. :crying:
On the downloading screen in ODIN mode it says
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
WARRANTY BIT: 1
Have I really messed it up?
Also if I try to install 4.2.2 official stock again it says: Unsupported Version
What can I try next? Flashtool?
Thanks

[Q] Note 10.1 (N8000) cannot upgrade to KitKat, Odin, KIES and OTA fails

Hello everyone
So, I fixed the problem of my tablet being bricked by installing the factory stock 4.0.4 ROM on it, and it has been my go-to resolution for the past couple of days, while I have been struggling to get the upgrade I have been waiting for, for so long.
However, no matter what I seem to do, my device just will not accept the upgrade, and I cannot understand why. Here is what I have done.
Number 1
My android was running a stock 4.1.2 downloaded from Sammobile. I am not sure of the country/region I downloaded at the time, but I think it was either German or from the U.K. I bought my N8000 in China and flashing the firmware to get access to Google stuff was the first thing I did and then upgraded via Sammobile, formerly samfirmware I think. When I saw the 4.4.2 KitKat on Sammobile I downloaded the German upgrade, flashed via Odin like I always had done, and it failed.
I then went on to try via KIES and it did say, that a firmware upgrade was available, however it got stuck and my device bricked. Which led to my 2-day marathon flashing of roms to try and fix it.
Number 2
Flashed the factory 4.0.1 rom using ODIN 1.83, factory reset + cache wipe and then Odin flash the 4.4.2 - Failed in ODIN.
Number 3
Flashed the factory 4.0.1 rom using ODIN 1.83, factory reset + cache wipe and then - Used OTA from settings to upgrade my device. This works until 4.1.2 and then I am told that my device has been modified and that no upgrades are available.
I then try to Odin Flash the Indian 4.4.2 from Sammobile - Failed in Odin
Number 4
Flashed the factory 4.0.1 rom using ODIN 1.83, factory reset + cache wipe and then OTA to 4.1.2. Then I connect to KIES to download the firmware upgrade and it fails and device bricks.
Number 5
Flashed the factory 4.0.1 rom using ODIN 1.83, factory reset + cache wipe and then OTA to 4.1.2. Then I root the device with Framaroot and install triangle away and use the system status modification to trick my tablet into thinking, or realizing, that it is in fact an official.
The OTA upgrade is now available, 800MB downloaded and installation begins, but the process fails and I am left in 4.1.2. I try again, same result. I flash via Odin, it fails, I try Kies it bricks.
Is it just me or is my tablet actively fighting me on this?
Is there anything I can do? Any suggestions? China is not exactly full of Samsung Service Centers, although I am sure a big city like Chongqing has one or two?

Bricked the S6 SM-920I. I'm at wits' end.

I got the Galaxy S6 yesterday and coming from Nexus 5, I wanted to remove the existing bloatware by flashing the XtrestoLite Deodexed ROM. This one here: http://forum.xda-developers.com/galaxy-s6/samsung-galaxy-s-6--s-6-edge-unified-development/rom-xtrestolite-deodexed-mod-edition-1-3-t3119968
I'm haven't had much experience in rooting and it's my first time flashing a custom ROM. The phone was running on Android 5.1.1.
Apparently I failed. I started with CF-Root but I wasn't sure if it was done correctly. This was followed by TWRP 2.8.7.1 . Then I tried booting up the phone and the boot logo just loops. I tried to wipe the cache as well as the Delvik-cache through TWRP but it's still the same. Then I tried to flash the stock ROM that I found online but I got the error "Nand Write Start" followed by "Fail". I seem to have tried everything and now I just want to get the phone to work again. It shouldn't be so hard.
Someone help me please :crying:
Have you tried to flash the stock rom via Smart Switch software? There's an option in the top of the window where it says "More" called Emergency Recovery. When my S6 bricked nothing but that did the trick, you should give it a try.

How did you do it? I've installed the Smart Switch software but the device doesn't appear under the list in emergency software recovery, so I can't proceed.
Edit: I managed to do it through initialization. I'll update when it's done.
Edit 2: It worked! Thanks so much!

Your PC is recognizing your phone? If not maybe you shall update your drivers first. My S6 is the same model number as yours and it does appears in the Emergency Recovery list.
Another solution could be trying to flash using another version of Odin; I saw a similar problem on another forum and it was solved using Odin 3.10 to reflash the stock firmware.
Also remember that you can't downgrade your firmware once that you are on 5.1.1, no 5.02 or so allowed.

By the sounds of it you're able to boot into twrp? If so then simply boot into twrp, connect to your computer and copy a flashable rom to your phone and install it using twrp instead of odin

How could I transfer the flashable ROM to the phone when I can't have it boot up to connect to my computer?

Since you're using the same model as mine, what are you running on your S6 right now? Are you able to root and flash a custom ROM like XtrestroLite onto Android 5.1.1?
Can you guys help me check if this post has the correct steps or is it missing anything like bootloader and root?

Actually yeah. Earlier tonight I flashed XtreStoLite over stock 5.1.1, but I must confess it wasn't as easy as I thought, mainly because I didn't followed the steps in the right way and I ended up having to root my phone through installing UniKernel, which is pre-rooted and that did the trick for me, because I got stuck in the Samsung logo right after I tried to flash with CF-AutoRoot, needless to say I obviously couldn't root with that method and had to reflash stock 5.1.1 firmware to unbrick my phone, install UniKernel, and after that I was able to enter my phone config, uncheck the reactivation block under Find My Mobile settings (which was the reason for me to get stuck at the S-logo) and then flash through Odin XtreStoLite deodexed and Xposed FW too, so I can tell you for sure that SM-G920I can run XSL like a charm.

1. So what is the correct order?
2. Did you have to manually unlock bootloader?
3. And is it a must to install uniKernel in order to root the device?
I have no idea how to proceed now.
This requires a lot more effort than I thought :fingers-crossed:
1. The correct order apparently WAS to flash 5.1.1 bootloader and modem over 5.0.2, then root, then TWRP, then flash XtreStoLite, or at least that was what I understood from Edgar's guide (as you can tell, I hurried myself too much and was to excited to flash XLS, so I didn't read properly).
Since I (and I think you did too) installed stock 5.1.1 first, there was no way to autoroot nor ping-pong root the device, that was the reason I got stuck in the Samsung logo screen after trying to autoroot, so I had to reflash stock 5.1.1 to regain access to the device settings/Find My Mobile as I explained before, after that I flashed UniKernel and that did the trick, no other steps were required to achieve root access beyond this point.
2. I didn't had to, but your carrier may have locked yours. My device is a SM-G920I (as yours) from Telcel carrier, so I can tell for sure.
3. There are several others way to root devices running over 5.0.2, but according to my personal research there aren't much options on 5.1.1 other than flash a pre-rooted kernel, but UniKernel isn't the only pre-rooted kernel, so you can choose whichever you like the most.
If I were you the first thing I'd try, as I said earlier, would be to switch to another Odin version or another firmware (as long as it is 5.1.1) and if that don't do the trick, then I'd update drivers and try via Smart Switch again.

What did you use to root? May I ask for the link? I just tried flashing CF AutoRoot and now I think it's bricked again. (RECOVERY IS NOT SEANDROID ENFORCING) I'm thinking it might be due to incompatibility because I got it from here (https://autoroot.chainfire.eu/#odin) and the Android version states 5.0.2.

Yep, that was the exact moment where mine got stuck too, as I stated before at that time I had to reflash stock firmware. The trouble is caused by CF-Autoroot, it won't work at all when you're on 5.1.1 (at least with SM-G920I) and if you try to root using this method, you'll get stuck with the message "RECOVERY IS NOT SEANDROID ENFORCING". You'll have to reflash to stock too, I'm affraid...
Flash UniKernel via Odin once you're on 5.1.1 stock again and see the magic happen. Once you have root access, gained by this kernel, you can install TWRP and flash XtreStoLite or any other rom you may want. Here is the direct link to the post: http://forum.xda-developers.com/galaxy-s6/samsung-galaxy-s-6--s-6-edge-unified-development/kernel-stockmod-kernel-t3100395
Hope you get lucky.

I just did that before you suggested it and it worked! I was so elated! I love you bro (no homo). Our situations are identical. Now I have XtrestroLite running on the S6! Thank you so much!
Simply put:
1. Update bootloader and modem
2. Install TWRP without root via Odin
3. Install UniKernel via TWRP
4. Install ROMs!

Auto-Root always bricking my phone!

Hey, I need a little help here.
Been trying to root my S7 on Nougat several times now and it always fails. I've wiped my data and cache, installed the newest stock firmware with Odin several times now, but whenever I try to root it via Auto-root my S7 gets stuck booting on the Samsung logo forever.
- S7 Nougat up to date
- Odin version: 3.12.3
- Auto-root for my phone from chainfire
Well now I've had enough of that **** and I'm here asking for help. How do I get out of this bootloop without having to wipe all my data again? I just want my phone rooted finally. I do not want to have to install the stock firmware again and set everything up again!
Just bought my galaxy s7 yesterday and had exactly the same problem. After some researches i found out that autoroot was not working with nougat. You need to flash TWRP using ODIN and then flash SuperSU from TWRP. Hope I helped you.

In desperate need of some help.

Hi,
I'm stuck with a custom rom and I can't quite get back to stock. I had rooted my device and installed twrp, and I was in need of an update, hence tried flashing the stock recovery and then trying to update but that didn't work either. My Honor View 10 somehow ended in a boot loop and I had to flash twrp and a custom rom to get it started. Now I can't quite get back to stock.
I have tried fastboot flashing recovery.img of stock firmware, have tried normal and forced upgrade too, nothing worked out. Any help will be appreciated.
By any chance it is Indian firmware?
