Bootloop after deleted SELinuxModeChanger - Android Q&A, Help & Troubleshooting

Hi there,
I am at a loss.
Zemana antivirus asked if I wanted to make SELinuxModeChanger a system app. I agreed.
Well, later on I realized that I didn't need that app anymore, so I tried to delete it via ES File Manager. Failed, but some files of the app became deleted anyway.
There was no problem till I restarted my phone. It boots the phone's logo then it stuck.
Safe mode doesn't work. Factory reset doesn't work.
I connected my phone to PC, but the computer doesn't see my phone.
Power and volume up held down power let of when logo boots. Power down again.
Phone writes "No command" -- I guess that's the chance when I should give it a command, but how and what?
Then press Power:
Menu
update from sd
update from adb
wipe/factory reset
restore user recovery
wipe catch
None of them work.
Phone created many recovery data... Each of them is useless.
Android 4.4.2 phone Navon D402 rooted with King Root.
Any suggestions?
You are my last and only hope.
Thanks in advance!

HELP! SGP (YP-G70) bricked after rebooting directly from Font Changer

Today, I decided to use a font that I cannot find at the flipfont directory here at XDA. I downloaded and loaded up to Font Changer. When Font Changer said that changes need to be made via rebooting, I chose to "reboot later". However, it didn't work. So I decided to reboot directly from the app. This is where everything went wrong.
When the device is done booting, the screen is half unresponsive and the screen keeps on blinking. It does not let me choose the launcher that I have and it does not let me use the home keys, as they are not functioning properly. It just keeps on repeating the action of "Media Scanner Running", and keeps on saying that the "status bar" activity is unresponsive.
Luckily, I can plug in it via. USB into mass storage mode to do a backup. Is there anyway to solve this in a simple way that does not require wiping data via. ODIN?
Thanks in advance!
Do you have an SD card installed?
Mine got stuck on a "Scanning media" once and I removed the SD card and rebooted,
and then it booted fine.

The problem is that I don't, as I just used the on board memory. I even resorted to Safe Mode several times, but it just froze when I approached settings menu and continued to do the endless boot-loop.
What ROM are you using? If you are using those with CWM Recovery, you can try rebooting to CWM (Vol up+Home+Power) and wipe your data/factory reset there.
If you don't have CWM Recovery, the best bet is to reflash your device using Odin. Is your device international or US?

[Q] Can't access recovery nor reset to factory settings on rooted device

Hello,
I own an Android tablet KO PARA1 FULL and experiencing a strange problem. This is a chinese atm7029 quadcore tablet (16gb, 1gb ram, without bluetooth, only wifi, bu supports 3g dongle), running android 4.1.1 nad 3.4.0+ kernel, which came prerooted. After some time I've decided to install backup programs on in to make a full backup of the device for the case something would go wrong, and after some trying I descovered, that there is something like recovery for that purposes which seemed a good solution for me. I decided to install CWM, which I managed to install without problems and made some backups on my device. Everything was fine, I did some factory resets through the time, some restoring processes from my previously backup states of the device, was always able to activate CWM recovery menu through Reboot to recovery or through combination of Volume down a Power button...
Until last saturday. I was normaly surfing the internet, reading mails and afterwords I powered my tablet off (it is draining battery in sleep mode, but its another story..). After a while wanted again to write a mail, so I powered it on. In that momet seemed the screen too dirty for me and I tried to cleen it little bit throug the bootup process. Unfortunately I obvious confused the system with it and after boot it was not responding properly. I did not wait enough and after a while powered it off with power key pressed for a long time, to make a new boot.
But when I powered it on again, it stayed stuck in boot logo and did not boot at all. I've tried a copple of times to boot it again with no cuccess, stayed stuck in boot logo for more then 10 min...
Afterwards I decided to make it boot up with the help of computer. I downloaded adb and drivers and somehow managed to make it boot up. I thing I was too excited to see it boot up again, that during boot up process I desconected my device from computer...
My worries were reliesed and I thought it would be a good idea to make a restore from backup to prevent some strange behaviour, so wanted to boot into recovery, but nothing had happened. After some repeated clicks on Boot into recovery button, as well as app called rebooter with nothing happening, I decided to try it out through button combination. It has not worked as well Next try was to reset to factory settings. But when I go through the menu, I can click on reset to factory settings button, seeing warning that I will lost ma data, then I can push the button to make it happen, but nothing is happening. I see only the screen with the button, can touch it 100 times and the tablet stays on, fully funcional. making no factory reset as it done before.
I did a lot of reading and searching, but have not find answer for my problem. I flashed recovery images from my backups (using flashify, flash gordon, adb shell, terminal emulator), from all previously functional states of the device. I refleshed the CWM recovery downloaded from the internet for my chipset, which previously did the job just perfect, with no success...
I am still not able to reach recovery menu. For me it seems like the bootloader would be locked, but I did not find the answer how to unlock it without to be able to start in some recovery state to use fastboot command to unlock it.
Otherwise, my device is functional, still rooted, i can use it without any other problems. But not be able to do recovery from my backups, even do a factory reset.
How can I restore my access to recovery mode? Is it somehow possible?
Hopfully it is not too much information (tryied to follow the intructions and wrote everything I thought would be important to know about) and you will not be bothered to read all my story and pull me out of my darkness with helpfull suggestion.
Thanks a lot in advance

[Q] Stuck in boot loop, exhausted almost all optons

LG Escape running 4.1.2
here is the progression of events:
1. rooted device
2. root seemed successful and no malfunctions
3. backed up all apps and system data with Titanium backup
4. the lg escape has no way to unlock the bootloader, so I tried various other methods. one of which was entering recovery mode via terminal commands. this is basically a hard reset, and it wiped all my data
5. I restored all my apps and data from my external sd card with titanium
My best guess is this is where something went wrong
6. upon restoration it prompted me to reboot the device
7. reboot passes manufacturer logo, but resets when AT$T logo appears
8. as stated earlier, there is no way to enter recovery mode during boot.
9. there is a hard reset during boot, but mine will not work, as it requires touching buttons which do not seem to be active in my stage of the boot sequence
so, I understand this does NOT mean my phone is bricked, but I don't know how else to get it to boot back up, or what is even causing the boot loop, as I DO NOT HAVE ANY CUSTOM ROMS flashed. any help here is very appreciated!
EDIT: so I have attempted to use adb on my pc to reboot into recovery from there, but it occurred to me that while I was in recovery the first time, I never checked "usb debugging". as a result my adb console commands cant even see my device. any way to turn on usb debugging while locked in a boot loop?
also, I can get it to enter download mode. I was hoping I could just reflash the firmware to it without needing to enable usb debugging, but have no clue how to do that while locked out of the phone.
I realize this is a very specialized set of questions, but it is necessary to ask here as the most people will see it. im open to any ideas

i have now tried to flash the firmware while in download mode using a less than legitimately obtained lg R&D tool. however, i need V10F_00.kdz and i am facing a bit of censorship. any kind soul willing to host this file on dropbox or similar so i can download it?
Usually devices have a button combination to press when powering on to get into different modes. Maybe try searching for the button combination of your phone on Google? Try ' lg escape button recovery ' ?

believe me i have. the only combo i can get to is download mode. there is a combo for a hard reset, but my touch buttons arent active during boot.

[Q] Stuck at Samsung splash screen - Need to backup data

The phone was working fine until the battery was empty. I tried to charge it and turn it on, but it's stuck at the Samsung logo splash screen. Holding the power button only restarts the device, so to turn it off I'll have to take the battery out. I don't know how to fix this, and if a factory reset is the only option, I need to backup my data first which I currently don't know how to either (without accessing the OS).
I've got to the Android System Recovery 3e menu and tried clearing cache, which did not help. The option to do a factory reset is also there, but I need to backup my data first, and I don't even know if this will fix the problem.
I'm also able to enter download mode.
When connected to my PC it detects an unknown device named 'samsung_android", and it shows up in adb. I've tried doing a backup through adb, but it wanted me to unlock the screen to accept the backup, which I could not, because I'm stuck at the splash screen.
Is there anything I can do to save my data? Anything through adb? Install root (never done this before)?

Hey mate, can you get into the recovery mode? Try flashing the TWRP recovery and boot by pressing power button + home button + volume up and find an option to mount your USB storage via USB cable and see if your phone's folder tree is available from the Windows Explorer and hopefully you can backup your data by then. Just make sure you have all the drivers ready.
Hope that helps.

Yeah, I can get into recovery mode. But how do I get the TWRP to my phone? Do I have to put it on my external memory card and then load it from there?
And I could only find it for a S2 Exhilarate SGH-i577 device. Does it matter if my phone is a S2 GT-I9100?
I've never rooted my phone earlier. Is a root necessary to flash a ROM?

Correct. Put the TWRP zip on your external and flash it normally via recovery mode such as CWM not the android 3e recovery. Or find an odin flashable zip for yoyr device.
I am very sure there is one for I9100 because I ran into the exact same problem before and managed to figure it out. You just have to search for it can't give you a link because I'm on mobile now.
You need to root your phone in order to install a new recovery such as TWRP/CWM or even flash new kernel and ROM.
Good luck.

[Q]DigiLand DL1010Q softbricked

Ok, here is the deal and I hope someone can help me. I have a cheap DigiLand DL1010Q tablet to play around with. It is stock, but I rooted it with KingRoot. There was a recent OTA wireless update and after it was installed it said that it needed to go into recovery mode to install and reboot. I selected install now and reboot. This is where my problem started and has remained. It loaded into recovery mode and is in an endless boot loop. I've tried rebooting it, recovery with the recovery file and every manual reset possible to no avail. DigiLand support said that I should power down the tablet, and while holding down the Volume Down (-) hit the power button and it will boot into a Chinese recovery mode. I've tried that and it just stays on the DigiLand screen forever. (I left it there for 8 hours.) I can sideload via ADB and the drivers are installed, but it will not let me load anything. It states that the bootloader is closed. I receive the same message via Fastboot. Now here is the interesting thing. Even after selecting the factory reset within the Recovery Mode, everything is still there. I have wiped the cache and partition and user data, but nothing really happens. It is still all there. I see the recovery file, but it will not load. All I see is NO Command.
I do have a sd card that I could flash things on, but it doesn't seem to register the card. It sees the sdcard, but that is the internal drive. How do I get it to look at the sdcard that I put into the slot? Is there a bootloader unlock? Does anyone have the factory image that I can put on my sdcard? HELP!!!!
I am fairly good with computers and have rooted phones and tablets before, but I seem to be hitting my head on a bricked wall - no pun intended. Let me know what programs, files or whatever. At this point I am willing to try anything. I can send it back to China for $50 for them to redo it, but I only paid $69 for it and I'm not going to put more money into this cheap tablet. I would just like to get it to work.
