Galaxy Tab4 soft-bricked with SOTI - Galaxy Tab 4 Q&A, Help & Troubleshooting

Please pardon if this is a duplicate thread. I looked all the way back to July '15, but didn't find anything similar... Apologize in advance for the long intro, but want to give as much background as possible to see if anyone can help find a solution. I have several Galaxy Tab4 8.0 tablets (model SM-T337V). When purchased, they were running Android 4.4.4. I enrolled them in an MDM environment (SOTI MobiControl) and everything was working fine. Through the MDM software, I was using a custom lock screen, which I believe Samsung calls kiosk mode, and had selected the option to NOT allow factory resets. When Android 5.1.1 (pretty sure) came out, it prompted tablet users to upgrade, which several did before I was able to intervene. When those tablets were upgraded to the new OS, it became incompatible with the version of MDM that was installed (v11.02). Now, the tablets will boot, but after swiping the home screen, I just get a black screen, and a dialog box that reads "Unfortunately, MobiControl has stopped" repeatedly comes up. I can't get to the settings or anything, due to the settings of the MDM software. I can get into the "recovery booting" screen by holding the home/volume up/power buttons to turn on. Get the full menu, but cannot do a factory reset due to the settings held by the MDM software. If I connect to a PC via USB cable, I can see the device, but cannot get to any of the system files to remove the MDM software. I'm hoping that someone will know of a way to get into the device and bypass the old MDM settings so that I can reset and use the tablets again. Please let me know if there is any other information you may need to assist.
Thanks for the help!!

Booting into safemode disables 3rd party apps,
for your device, it should be the following;
power off device
poweron device, as soon as you see the samsung bootsplash press and hold down the volume down button,
you will know if you did it correctly when you see safe mode at the bottom left of the screen and a notification in drawer,
if that does the trick, after you remove the offending software, pull down and click on the safemode notification.

Thanks for the quick reply!! Well, the first one, I must have held the volume-down button too soon. It stopped booting at the red Verizon screen and won't do anything else. The second two, I held the volume-down at the colorful Samsung splash. Am getting a dialog box that says "Android is starting..." with moving circle and "Starting apps.", but, again, no further bootup.

Hermes wont boot - 4 color bars - help please

Hello everyone. After some researching, this seemed like the best site to answer my question, as I have not found an answer yet.
Yesterday morning, I was running my ATT 8525 (which I believe you refer to as "hermes") just fine. I was using the internet sharing feature, and went to reset the phone. I "believe" I pressed the power button while pressing the "ptt- push to talk" - button. The phone turned off, and when I turned the phone back on, rather than loading like it normally did, I got a new screen.
The screen has 4 color bars. A red bar at the top, then a green bar, then a blue bar, and last, a white bar of color on the bottom. Each bar takes up 1/4 of the screen and runs horizontally. At the top, the phone says, in white text:
HERM100
1PL-1.04
HERM100
SPL-2.03
At the bottom of the screen, in the white bar of color, in black text, it says
SERIAL
Now, when I press the power button to turn the phone off, nothing happens. I have to remove the battery to shut off the power. If I plug in a USB cable, the SERIAL text changes to USB. If I press the top two buttons, the one above window and the one above ok, while pressing the stick in to reset the phone, that screen works ok. I believe it is called a "hard reset" It asks if I want to erase all data and restore factory settings, and if so, press r. I press R on the keyboard, and the screen then says reset complete, press space. I press space and then I am back to the screen with 4 color bars. Nothing else I have tried works either. I have been stuck on this screen with 4 color bars since yesterday.
I took my cell phone in to ATT to be looked at and the sales people at the store say that I am 7 days past my warranty, and that they can't/won't repair the phone, but they would be happy to sell me a brand new one... for several hundred dollars.
So, the folks on the internet are my last hope =( If anyone reading this knows anything, even if it is a link to another site or something, that may help me resolve this problem, I would greatly appreciate it. If not, I at least thank you for your time reading my post.

Oh, as an additional thought, if it helps, I have not used any of these :baked: roms or any such thing. I bought my phone and used it as is. The one and only change I ever did to my phone was I followed ATT's steps on upgrading from Windows Mobile 5 to Windows Mobile 6, if I remember their names correctly. Hope this helps.
Bootloader. This is the name of the screen according to my research.
"Is your device able to boot Windows Mobile OS?
This one is easy: If can you see your today screen and use your phone as a PDA means you can boot OS. If you only see the splash screen, bootloader screen (tri-color) or windows mobile splash screen you can't boot OS."
Got this from the thread at
http://wiki.xda-developers.com/index.php?pagename=Hermes_Unbrick
So, I guess I am stuck at the bootloader screen.
Try a Hard reset - hold both soft keys and reset with stylus. Hold in until it asks to reset to factory (whatever). Press "r" on the slideout keyboard and then space. You should go back throught the setup PPC steps.
YOU WILL LOOSE ALL INFORMATION ON YOUR HERMES...This is unescapable as you would any other way you tried to recover your Hermes too.
I suggest if you get it working to install Hard SPL V7 (makes recovery easier) and also pim backup so you can restore all your contacts/messages if something goes wrong again.
Cheers... & good luck.
I have tried hard resetting many times, and it does not work. It says that it succeeds and that factory settings have been restored, and then I am back to the bootloader screen. I have been to the wiki on bricked hermes phones and recovering from a brick. From that, I ascertain I have a type 2 bricked phone (goes directly to bootloader screen). I tried the MTTY tool, and it says that the NAND write was successful on both commands, but, I am still stuck at bootloader screen. I have since tried installing a few different roms, even in SSLL and HARDSPL modes, and nothing has worked.
What I have not tried is the JPIN fix, as I am not an engineer and don't have the tools or knowledge on how to do that. I also don't know how to do the microsoft operating system download fix (using an emulator?)
** UPDATE **
I think it might have been the mtty commands, but I took the battery out overnight, and when I put the battery back in to try the KITL attempt, the phone booted up and started to do the config. I was happy and thought that the phone was fixed, but when it was done with the configurating the phone, it reset back into boot loader screen -_-
You may need to check for bad blocks. This sometimes causes the problems you descibe as well as spontaneous Hard Resets and occasional soft resets.
Do a search for "how to fix bad blocks hermes" and you should get the info you need...
Hope this helps...

[Q] how to do a total format?

Hi,
I’ve locked screen by a soft (don’t know the name of it) that remembers a gesture (you must connect at least 4 of 9 points) that you must repeat to release the screen.
Unfortunately I have forgotten the gesture I’ve set and after 20 tries the soft blocked for good. Now it wants me to login to Google account to unlock the device – but it doesn’t work.
I did a factory reset but still this app locks screen after turning the phone on. (note that in the “factory” menu there was a red line telling something like “cannot read: system/era/...” – the factory reset has completed successfully)
Probably there is no chance to release the screen, so please tell me how to do a total format, to delete all apps?
Thanks!
Tom
Boot into safe mode by doing a cold startup while holding onto the home button before power button. Keep holding onto it til you see the word safe at bottom of screen. Then remove that app like normal. If no good then hold volume up plus home button then power. It might take a few tries. Once in recovery mode move down with volume button then select one of the options but not the update.zip one with home button as enter

The factory reset would have remove the offending software
Was it software you installed or the default software built into the Firmware.
Namely the Location and security (Screen unlock pattern).
If it's built into the firmware then your going to have to reflash the device.
ickyboo: There is no "save mode" as you suggested or it just doesn't help
I also did a factory reset and this app still blocks the screen.
Ancient_One: yes, probably it was a default soft. I wish I could remember the name of it :-/ I'll try to find this somewhere, maybe I'll recognise the icon.
But I'm afraid I really need to reflash the device.

i try that seem to have no response and when unplugged from usb it loop at&t logo
or plugged in usb screen goes black and no response seem from pressing buttons
I had a similar problem as most phones in Canada seem to have Download/Recovery mode disabled, and here is what worked for me.
Grab something like One Click Un Root (all models), and click one click un root (obviously phone has to be on and plugged into the computer).
This should automatically reboot you into Recovery Mode!
All you have to do is "wipe data/factory default" or something like that (should be the third option).
As it states, you will loose all your data, but at least you will have a functionning phone!
did it work?
Hi. I have similar problem. Can anybody give instruction what can I do?
I have this problem too. Please help somebody
Add me to the list. Bell Galaxy S, went to unlock my phone the screen went black. Now it will not boot into the OS, the galaxy S splash screen displays then nothing. The menu and back button light up, thats all. ****[email protected]@
I have not rooted or anything.
Of course my download mode does not work.. Going to try this one click root thing if I can find it.
NOT HAPPY
This is not working. Probably because the phone is not in USB debugging mode as I can't change it... Is there any other way to get the phone into recovery mode?
**** me
i had the same thing happen to me the other day with my bell galaxy s and my phone wont do the 3 button combo trick. i left my phone plugged in to a wall charger for a while until the back of the phone became a little warm. i pulled the battery and then left the power cord plugged in and put the battery back in. i held the volume down and enter button until the battery charging indicator showed up, then i also pressed and held the power button until the boot animation started (this is the blue moving swirl and music, not the galaxy s splash scree) and then i let go of the power button. it took a few attempts at this before it actually worked, but eventually it will go into download mode at which time you can open the odin app, then plug in the usb cable and flash your phone that way. it did seem to make a difference if the back of the phone (around the camera area) was warm. if i let go of the power button while the music was playing and the phone did not enter download mode i would keep all 3 buttons pressed until it shut down again, then i would only let go of the power button while the phone initiated the charging screen, then once the battery logo was displayed i would hold the 3 buttons again and would just keep doing this until it went into download mode. i have flashed it at least 5 times today and i have been able to do this each time.
i also had an issue where odin would not recognize my phone was plugged in and windows would show a message saying the usb device was not recognized. i left the phone plugged in and while in download mode i pressed the volume up, enter button and power button until the phone went blank and when the galaxy s logo showed up i let go of the power button and the phone would go into recovery mode and then the usb drivers would be installed. i would then do the 3 button combo for download mode and odin would work fine. it took several attempts but it does work. i hope this helps you guys
If I hold all three buttons the splash screen does not come on, it just keeps looping the Galaxy S logo until I let go of the power button....

That's what mine did too, several times in a row and then it worked. For some reason it only works after the battery is charging for a bit and the back becomes warm. then it works at will
No luck. I am probably screwed getting it exchanged now too as I am passed the 14 days from Best Buy.
the on click thing doesn't work, if your phone is already bricked.
also it is not the phone's fault for not working, the phone was working properly before you tried the hacks.
whenever you do these kind of things you know you are entering into the "not supported" "not covered by warranty" zone.
in the worse case scenario, if you can no enter download mode to recover your phone, it'll be to take the phone back to bell and claim warranty on it, and prentent you don't know what happened to it.

Its my fault??
I did not hack my phone. Its not rooted, I did nothing to it.
By "unlock" I meant exactly that, unlock as in swiping the screen to unlock it.
The more I search the net the more posts I find of Galaxy S phones randomly bricking...
on the original message sounded more like you went to Unlock the phone, as in SIM unlock the phone using any of the tools available out there, and there has been already several people which had the same problem.
if you go back to Bell for an exchange, you better not use the word "unlock" rather use Swipe
as the message on the phone "swipe the screen to unlock"
there are no known issue about this causing the phone to brick.
if that is what happened to you, you should have started a new topic for people to help you, instead of hijacking the topic from the OP, as your issue is different from OP, the OP actually screwed up because he/she flashed the wrong ROM to the i9000
... anyways, Does it work if you reboot the phone?
I have rebooted the phone about 100 times. The phone crashed when I unlocked it to check a text I received. (not hacked). Has not booted up properly since. I have found many others with the same issue who have also not hacked/rooted/unlocked/ their phones.
Waiting on Best Buy to call me back. I am so pissed right now, I have been bragging to my friends and co-workers how awesome this phone is, one has already picked one up, I hope his doesn't brick too. Not recommending it to anyone anymore..
did you load a lot of MP3 to the phone?
can you boot into Recovery Mode?
in the recovery mode you can wipe the Cache and wipe the data
that should make your phone work normal again
it'll be best to open a topic to help you trouble shoot your interesting issue, as it's the first i've hear that you get a black screen after Swiping out of the lock screen
I can't get into recovery mode. I have tried every button combination I have found. I had about 2 GB of music on the phone. I also installed the Android SDK to try ADB, but since the phone is not in USB debugging mode it does not see it.

on the other topics relating to the 3 button not working.
have you tried the heating up method?
or the plugging the battery in, when all 3 buttons are pressed? (of course for this one you will need help from a friend, unless you are very skilled at keeping the 3 button on hold meanwhile able to slide in the battery in with out a 3rd hand)

[Q] Please help me

As suggested, starting a new thread.
Hello,
Straight to the point, Rooted UK Atrix, running 2.3.4. no other MOD OR rom or anything, i like motoblur.
Stupidly Used Bloatfreezer to freeze 'home' without having another launcher to return to. Can't use the phone now. Trying to reset (hard or soft i do not know the difference) and the phone reads ''fastboot'' then i toggle down using volume - to android recovery and the phone is coming up with starting rsd protocol x2 and nothing else (using the power + & - methods).
If i leave my phone to just boot it resides on a white screen teasing me with noises of logging in but i cannot see anything.
I'm really lost to be honest, i have no idea what to do and i am not good with terminology either (adw, flashboots, cm7 i have no idea what they are).
I know there are sooo many threads with different answer's so that is why i am starting a new thread.
To factory reset using recovery...
1.Power off the phone, press and hold volume down button, press power button.
2.Screen will come up with "Fastboot", press Vol down key to cycle through choices until you get "Android Recovery", press Vol up key
3.Wait for the "triangle ! / Android" screen then release the volume down button
*4.Tap on bottom right corner of the screen (may take a few times). a menu will come up
5.Tap on "wipe data/factory reset", and press OK. Another Confirmation screen will come. Press Yes and OK
6.After userdata is cleared, the "reboot system now" option will be highlighted by Default. Press OK.
7.Phone will reboot to initial setup MOTOBLUR screen.
NOTE/If on Android 2.3.4 then replace step #4 with pressing both Volume buttons at the same time. Also, use the Power button to activate the highlighted option instead of looking for the OK.

Can you get to android market via your computer? If so go to it, log in, find a launcher and install to your phone. Once rebooted to the phone, it *should* give you a choice or just automatically choose the new launcher. What does double tapping your home button bring you too? I was able to find my alternative launcher by moving around via that.
sounds like ya have frozen system files
prolly be easyest to unlock bootloader and push a custom rom to it (they work better than stock anyway
Yes i did freeze the home app.
I really mean thanks to those replied. Unfortunately i have tried the first suggestion but it doesn't let me get to step 3 with the triangle, fast boot - android recovery - can't fast boot 2 etc can't get passed that.
i have just plugged it in the Laptop, taking sim out, and it has started! i thought it was broken!! but unfortunately not 'home' yet...
SO it is at the motoblur login screen, should i log in? press factory reset? Any suggestions?
I'm not sure how to push an app straight to phone so i can install a launcher...
we're nearly there guys!
In addition to what Robkort said a few posts up ^^^ to get into the recovery on 2.3.4 you may have to scroll down once you see fastboot, until you see "Android Recovery" and press vol up - when the android dude comes up, if tapping the bottom right corner doesnt get you into recovery, press BOTH volume buttons at the same time.
It is now up and working with me just simply plugging it in, running moto sync, logging in to market from laptop and sending the launcher app..
Wifi was enabled luckily before i froze home, so when i pressed log in it went 'error' then launcher pro just popped up so now i think i just unfreeze home, turn it off, put my sim in and fingers crossed..
wish me luck!
Yahooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!
It's worrying how much happier i am now that i am back on top with my phone working. Pretty dependant we become!
All my widgets, and motoblur have gone, and some writing is in a different language :/ universal inbox is not there either.
Still Thanks for all the suggestions!
I suggest this thread should be 'FROZEN' or just stay open if anyone ever freezes 'home' without having another launcher installed.
I'm glad i didn't need to flash anything, put other ROMS on, hard reset losing everything, solved pretty simple luckily.

[help] I think something is corrupted.

I initially had this phone and used it without messing with anything, just pretty much stock, until about a few weeks ago, it started giving messages stating, "xxx program has stopped" but it would be all of my programs like app stack and media.android (has stopped working) and it would only give me the option to stop the program or report feedback, in which i always stopped it. Then hell started when my phone started resetting itself. Then when it rebooted, it would either hang on the LG screen, or when it came back up, the phone would factory reset itself. I switched to iphone because i dont know what im doing with android stuff but i hate iphone so here I am. Ive tried to factory reset the phone from the volume down menu and the download menu(up volume menu), and im all out of ideas. thank you for your help, because im stuck. By the way I have a us993
if the phone can be powered off, you can connect the usb c in the phone (not yet on pc) and then keep the finger on volume down, then when keep the finger on volume down connect the other end of cable to pc, release the finger only when you see a blue square saying "Download Mode", and use LG Bridge to flash firmware, download the correct one for your version, or, better, try do "error recovery" on LG Bridge software.
hope this can fix your phone.
