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.
