I bought an a tablet from work that was a display,i got it really cheap,but i need help getting it to where i can use it.
Ok it is a Samsung Galaxy Tab 4 10.1 SM-T530NU.
The problem is it got password protected by some random customer,and when i try to factory reset it says "MDM does not allow factory reset".
i came across a video telling me how to get around it,but i have to be able to get into the device,and everything i look up about getting past a password says to just factory reset.
Plus everything i lookup about reinstalling android says i need to be enable USB debugging mode,but i can't due to the password.
I tried installing stock firmware using odin and it shows in recovery mode as a slighty different version,but the password is still in place,and it still says the same thing when i try to factory reset.
i even just tried to root it using CF Auto Root,and it still is doing the same thing.
So i am stuck and i have no idea what i can do to fix it, someone please help me...
EDITk i got it to work.
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 i put the device into download mode, and re-installed the stock rom.
when youre in download mode usb debugging is on.... no need to enable it in
rom. install twrp to it from odin, then do full wipe, reboot to recovery and clean install stock firmware that will kill all files and rom passwords.

Apologies if I'm in the wrong section.
I updated my s4 to lollipop via Odin and it was successful.
Problem is, when I go on apps like YouTube or Google Now. It says can't establish a reliable connection and it keeps happening. On my brother's phone it's fine. Today I booted into recovery mode to check if I installed CWM (just in case I forgot) then when I rebooted the phone, the screen was black and it was showing apps were force closing. I rebooted into recovery again, wiped cache yet still same problem so I reset the entire phone and when I tried signing into Google, it said can't establish a reliable connection and this happened once earlier. Can someone please help me!!
I have installed the correct firmware
I would start with a factory reset.
And CWM is highly outdated and shouldn't be used anymore. Use TWRP to avoid possible conflicts.
Yeah I do factory data resets but after doing it, when I try to sign into Google, it says 'can't find a reliable connection' then I'd have to flash the stock firmware via odin again. When I try installing TWRP on odin, it freezes. I tried different versions of odin but still freezes. It might be the TWRP I chose but I can't find any that end with md5
Hi everyone, just tried to root my i9507 S4 for the first time. Went really awful. I used the Chainfire Auto Root from his website for Android Lollipop (this one to be precise) and attempted to get it up and running through the included Samsung Odin. It booted in successfully and I could reach the home screen. I had SuperSU and could open it - but I think something stopped working along the way and everything crashed at once after just a few moments (whether I opened SuperSU or not). Google Play didn't open. I attempted to do a full-install from SuperSU, which got rid of SuperSU but the problems remained, awesome. Rebooting now changed nothing. So I went to Sammobile and downloaded the correct firmware (this one), and I attempted to restore with Odin using the same method as I did rooting. Everything seemed to be going to plan with Android "updating" and the like, and SuperSU is still gone, but the same problem remains. As expected all of my data remained. I'm tempted to do a full-reset at this point but I'd like you guys' opinion first. I'm new to all this - as you have probably guessed! - so please be nice-ish (I deserve some of the flack I'm sure). Thanks guys
Just attempted clearing cache thru recovery (stock) - no changes.
Full wipe then install firmware with Odin.
Through recovery I presume?
Do this: open Odin, uncheck everything except f reset time. Flash ROM. When you see the word reset in the Odin status window, remove USB cable from the phone, remove battery, replace battery, boot into stock recovery, perform a data/factory reset, reboot.
This method will wipe all of your data.

Would this not brick the device? Thanks though.
You only see the word reset if the firmware was flashed. I do this for the note 1, note 2, note 3, s2, s3, and s4.
so... my phone suddenly wouldn't accept my password anymore to unlock. i tried a couple of things, like deleting the files lockscreen files using TWRP to bypass that... but then it got stuck in a "android is booting" screen and everytime i tried to change my PIN, it would crash.
So i went to TWRP and wanted to reflash my ROM (I was using Resurrection Remix), but then I couldn't decrypt the data because ... the password again wouldn't work. so I finally decided to use sideload to try to flash everything again and it works, but the problem is that even after the factory reset, the phone will boot up but there won't be any images. You can hear the jingle play when you first turn on any android phone... but it's all black.
edit: I've tried flashing two different roms: RR & Lineage OS, both will boot up, but same problem.
I haven't been able to back anything up because... well the OS wouldn't boot up and my TWRP was being wonky and I can't restore anything...
Anyone have any ideas of how to fix this? I feel like i could use the format data and start from scratch... and make it work but then I assume that would wipe my titanium backups, which I haven't been able to extract out. so if anyone has any guidance on how to do that, that would be great. I've tried to use adb to extract stuff out but it hasn't worked and now I can't even do it anymore because I don't have usb debugging on.

have you try to re-flash your TWRP? maybe re-flasing your TWRP will work, also maybe installing the original rom will work, and then you can try to flash whatever rom you desire
as i know doing a factory reset from the TWRP delete all of your files, i mean everything. so i don't think that you still have the backup files
Flash the Official recovery of the oneplus 5 and then install OOS by adb into thé recovery.
I i had to reflash the firmware the correct one TB-X104F_S000024_180930_ROW_DCC. Anyway it wasn't booting at all before i flashed. Now it boots, shows the logo etc and constantly says Encryption unsuccessful!, so i reset it and factory reset it but nothing changes.
I have no idea where else to go, bootloader is locked and all i can do is flash the firmware. Would there be a way to remove this from the files within the firmware?. It seems like android is there in the background but i can't get away from that encryption unsuccessful screen!
Sorry if none of this makes sense.
Yo. I got the same tablet bro. Been trying to figure out a custom recovery for her. A stock ROM would be great to have and I haven't been able to find one anywhere. Might I inquire as to where you found yours? It would be a huge relief to know I can fix it if I break it lol.

If you download the Lenovo MOTO smart assistant from Lenovo support it has a resque option. I also used that to root my tb-x104f. It downloads the original everything and if you take the boot image from the file it downloads and replace it in one that has been modified from magisk it will rescue it and you will have root also thatd what I did with mine
same problem here, reflashed with stock rom. and not resloved

Did you fix this issue?
I am having the same problem.
Thanks
Same problem here (my error reads "Decryption unsuccesful", but I think it's the same as yours).
After a few tries, I believe that it is a problem with the internet connection. After the factory reset, if I skip the wifi connection step, it starts normally. And it is completely usable. I can load pdf documents or apks by the usb from a computer and it runs correctly. But whenever I try to set the wifi connection, it updates something and it causes the tablet that the next time I turn it off, I find the error on the picture when turning on. It asks for a password and no matter which password you enter, then it delivers this message.
In resume, right now it is a completely functional tablet if you NEVER connect it to the internet and load anything you need via usb or bluetooth.
I tried to reset it with Lenovo Smart Assistant, but the result is the same.
I am looking for custom roms to try if it's something about the stock rom, but I haven't found any. Can anyone reccomend me a rom for Lenovo E10 X104F 2GB?
Solution: (Worked for me)
Format Data as F2FS in TWRP. (Advanced Wipe)
Then reboot and wait.
So basically, few months ago i tried to root the phone, get new recovery and different rom. If I remember correctly I got stuck trying to get custom recovery to work, because everytime I restarted phone it would be replaced by the stock one. So I left the phone as it was, and disabled the TWRP app on it. Problem was, I could not update phone. Today I tried to completely revert to stock.
I flashed stock recovery but when I tried to install update from the phone storage, it did not even give me option to select a file.
I tried to update the recovery to newer one which gave me the option to select a file, but the installation got canceled after few seconds, putting me back on the file selection screen in recovery.
I tried to instal TWRP but I can't even boot into it at all because the phone is just stuck with blackscreen and lightblue led light.
I tried to ADB sideload the newest stock rom that I downloaded from OP5 site but this one went to around 50% and then crashed as well.
I also tried to do the update using the Settings>System update > Local Upgrade but this one also fails once it gets into recovery.
I tried wiping cache/reset system settings or wiping every data on the phone before any update but none of it seems to help and everytime I restart the phone afterwards the TWRP app is still there needing an update.
I tried to just lock the bootloader but I got the "Your device is corrupt. It can't be trusted and will not boot" message followed by link to google support. I assume that is because of the TWRP app that is on the phone but I can't get rid of it no matter what I try. I tried searching for people having simillar problems but I couldn't find anything that would help me.
Any suggestions?
Thanks in advance.
You can go with the last resort and use the Unbrick tool.
