MDM does not allow factory reset SM-T230 - Android Q&A, Help & Troubleshooting

Someone please help.
The last three nights I've been trying to recover an SM-T230 UK Samsung Tab 4 Wifi to factory ROM. This was a former live demo unit, I managed to get very cheaply.
The following is what I've done thus far:
- Removed Samsung Retail Mode using the 5444 code followed by the enabling of the factory reset function using the code M729Q16K8546.
This left me with a firmware that seemingly worked fine.
- I then went to recover to stock (minus demo mode) using home, vol up and power. When I selected the recovery option the message "MDM does not allow factory reset".
- Rebooted automatically. So checked the recovery option in the operating system. This was greyed out, so couldn't be selected.
- I then downloaded the stock firmware and recovered using Odin. This gave me back the option to recover within the operating system. But still the MDM arose when trying to using the button method to recover.
- I installed TWRP recovery firmware. Used this to wipe all data and recover the tablet to factory condition. This removed the OS at the same time. Upon reboot allowed the device to be rooted with SU.
- Then put the device into download mode, and re-installed the stock rom.
The device booted into the setup screen, as if completely wiped and reinstalled. However, although I can now recover from inside the menu, MDM message still shows if I try the pwr+volup+home buttons. I have tried multiple times to wipe and clear cache. The device works, but I need that button recovery method.
Sorry for the long post.
Thanks,
Carl.

Here's what I did when I got the same issue:
1. I booted into Clockwork recovery. Once there I wiped everything incl. "Dalvik Cache" and "Battery Stats" in advanced menu.
Manually formated every step in "Mounts and Storage" menu (EXCEPT FOR SDCARD of course!). Even tho that step might not be necessary
2. Did a factory reset.
3. Removed SD-card and put it in my putor. Then copied a ROM to the card.
4. Booted into download mode (hold Volume down + Home + Power buttton) and flashed a kernel with Odin.
5. Booted into Clockwork recovery and installed ROM from zip.
This worked like a Clockwork for me, No guarantees from me tho!

Samsung Galaxy 10.1 Stuck on Logo Screen

Hi, I recently rooted my Samsung Galaxy Tab 10.1 and everything was working fine. A couple of months later, I put the tablet in airplane mode because I didn't want to drain the battery when I wasn't at home. When I got home and removed it off airplane mode, the device appeared to be frozen so I held the power down to restart it; this normally fixed most issues I've had with it.
Only this time, it boots to the screen with the Samsung logo and is just stuck there. I was wondering since I did root my tablet, is there any way to restart it properly without doing a factory reset which will cause me to lose all my data/apps, etc...
Did you try to restart device from recovery?
Could you please describe what you mean by boot to recovery?
Hold power+volume down, you will be directed to recovery, there choose reboot device, if that wont help try factory reset, or flash stock rom through Odin
Any solutions that would not wipe the data?
If not is there a way for me to access the data and save it prior to me doing the factory wipe like hooking it up to my pc and transferring the data?
I have recovery but noticed I never took a backup. I am wondering if I did a backup now and did a factory wipe; would it wipe out the recovery/root? If not; would I be able to restore the backup and get my data back?
I tried the wiping cache but no luck; still just goes to the logo screen and no further.

I had this same problem on my tab. However, I just got out of it using the RECOVERY mode as was explained above.
It will not wipe your data. Just choose the option to reboot the system and that will fix it for you. I had same concern about wiping my data so when I saw that reboot option, I selected it and it has helped to rectify my issues. My tab has finally boot completely and I'm once again able to use my tab.

[Q] Is my phone fixable?

I have an S3 GT-I9300 and about a week ago it started refusing to turn on. It was fully charged, and I'd get LED indicators for messages, emails etc, but none of the buttons would switch on the screen, neither would unplugging the cable. The only way to fix it was to remove the battery, and after removing it one time, it refused to boot, sticking at the Samsung logo screen. Recovery mode wouldn't work, I tried resetting to factory settings, and wiping the phone, but it kept sticking (I think at cache), and wouldn't boot whatever I did.
I tried to update the firmware through Kies, which just froze at 94% every time. I also tried Odin, which again froze about the same point. So I tried following this guide, but when the phone restarted it tried looking for files on an SD card (which I don't have), so no luck. I tried repartitioning, but it keeps failing and if I try to flash the phone it now fails with "there is no PIT partition". I can't remember at which point it started happening, but although I can still get into download mode, switching the phone on any other way gives me a glitched screen something like this.
Is there any way at all to fix this phone at this point?
@edwards87: I'm confused about your description: no recovery mode, but factory reset? A root tool for rescue?
If you can boot into download mode, download actual firmware and Odin from sammobile.com (all new, delete old stuff) and try to flash it.

I can get into download mode (power + home + vol down), but can no longer get into recovery mode (power + home + vol up). When I could get into recovery mode right at the start, none of the recovery options did anything because it said there were missing files or directories.
I've tried several firmwares from sammobile through different versions of Odin and they all froze at the same place towards the end. Now none of them go anywhere because there's no PIT partition.
Then my next step would be a 3part-firmware +PIT-file.

Finally found a 3-part firmware but I get the same problem - repartition operation failed.
@edwards87: sounds like broken internal storage. Can't help you, sorry.

[Q] Factory reset from settings --> boot loop

My daughter's i9300 started resetting itself without control. Today it got unmanageable and a successful boot became impossible.
Looking around, I found a thread suggesting that the power button switch is the culprit.
Indeed, after removing the switch, everything worked fine. Had major issues starting the phone, but eventually it started, so I was good to go.
I rooted it, installed latest TWRP and Resurrection ROM. The ROM was a random pick more or less, I had it on my LG G3 at some point and I wanted lollipop.
All fine and dandy, I was able to get into the phone. However, data wasn't wiped even though I selected it for wiping in recovery (probably didn't select the right thing...). So I went to settings and chose factory reset with wiping all data.
This lead to phone rebooting to recovery, but TWRP logo just flashes every few seconds without ever getting to recovery itself.
How can I make this phone work again? Any ideas?
Boot into download mode then flash a full stock rom with Odin. If that works then factory reset in recovery before testing.
You may find the firmware won't flash, as it sounds like your nand memory is worn.

Recovering data from brick I9300

Hi, I'm completely new on all this mobile/android stuff, also sorry my poor English.
Out of nothing my phone bricked and I just wanted to recover my files from the internal storage.
Why I've tried so far: to install a custom recovery using Odin. Installation process were OK, I guess, judging by Odin and phone messages (on phone download mode you can read "custom binary download: YES (3 counts)". That's 3 because I've tried twrp-2.8.6.1-i9300 (tar) twice and recovery-clockwork-touch-6.0.4.4-i9300 (tar) once.
Where I'm stuck: I cannot see the options to access these recoveries form the recovery mode, just the already existing options (reboot, apply update, ...).
Thanks you for any help!

First of all flash chainfire auto-root. You can download it from here: https://download.chainfire.eu/229/CF-Root/CF-Auto-Root/CF-Auto-Root-m0-m0xx-gti9300.zip
Then try again to flash TWRP. If it will go ok, you can copy from recovery data from internal storage to sd card
Hi There,
I am in a similar predicament.
I have a Galaxy S3 (purchased in 2012) and a few weeks ago, the phone started to automatically switch off (when I locked it) and I would have to hold the power button for about 15-30 seconds for it to switch back on.
I checked the power button(to see if it was broken and pressing down all the time) but it seemed to be fine as whenever I pulled the battery, the phone would NOT come on unless I held the power button.
About 1 week ago when i tried to turn my phone on, with the power button, but it would get stuck on the samsung logo screen (it was frozen, not looping).
I was still able to enter both recovery and download mode. So I tried wiping the cache but it did nothing.
Then I tired flashing the ROM with ODIN and it passed but it also did nothing (tried flashing multiple times all with "PASS" as well as wiping the data cache in conjuction with the flashing but to no avail).
Tried flashing it again with BL and it also passed, but now whenever I try to enter Recovery Mode or Turn the phone ON it would display a White Scrambled Screen which probably means eMMC failure.
How do I retrieve the information on the phone ?
N.B;
- I do not care about fixing the phone, only want the information
-I cannot enter Recovery Mode, BUT I can enter download mode.
-When I connect S3 to PC it is detected (In Device Manager it states "Samsung Mobile USB CDC Composite Device")
-I did have my phone password protected before this happened using the Pattern Password (you have a 3x3 Dot grid in which you can use to draw a line(s) which will function as a password)
-My phone is an S3 GT-I9300
-Never interfered with the ROM or software on the phone before this (was running the official android software from Samsung which I believe was Android Version 4.3).
-I am not very versed with computer programming so please use simple words to help me
As previously stated. flash cf-autoroot and then flash twrp, both via odin. Then you should be able to access twrp (hold home and vol+/- (cant remember which, opposite from download mode) and press power once.
If you can get to twrp you can use its built in file manager to move your data to an sd card.
If no twrp its what is technically known as f*cked.
I wish I stole my HTC M9.

Short and sweet: TWRP is a popular recovery system; cf-autoroot is the preferred method for rooting some samsung devices by member Chainfire
I could lay out all that here again in detail, but it's safe to say you are better off in the long run if read up on that stuff by yourself...
Check the excellent threads I linked in my signature! Trust me, it's not as complicated as it seems.
