Boot-LOOPING after "simulate screen 1080p", please help! - LG Optimus 4X HD

Hi everyone,
I was playing around with the MHL function, trying to get any option to change the outgoing resolution. Under the developer options, I found something like "simulate 1080p (safe)". Then the phone crashed and since then it's only boot-looping until it eventually will freeze at the booting screen (boot screen -> restart -> boot screen -> restart -> boot screen -> freeze).
When it freezes, the adaptive brightness is working.
I hope so much I don't need to reflash (got the Paranoid ROM w/ KitKat and ClockWork Mod 6.xx).
I appreciate your help very much, so thanks in advance!
EDIT:
I found the saf mode option, but when it started up, com.android.systemui is crashing again and again. I can't do anything..

Ive deleted everything, problem solved

[Q] Cannot enter recovery, Screen turning randomly black, graphic (?) issues

Hello everyone,
first of all thanks for your amazing work and all the stuff you provide. I was a silent reader for a long time, but now my phone is trolling that much, I cannot fix it on my own/with the guides I found here.
I do have an HTC One M7, rooted (superuser) and S-OFF (revone) with Androidd Revolution HD 71.1. I used to update my ROM every month, but I got stuck after the last update. My recovery was TWRP as CWM did not work properly when I rooted my phone.
My issues as a list:
- cannot enter recovery anymore
- cannot connect via USB (tried every port)
- screen turning randomly black on homescreen and sometimes in apps (but they usually work), screen does work, but i cannot see a thing
- since today graphical issues after a reboot (flickering screen, parts of the screen get duplicated)
Since the last update I cannot enter recovery anymore. Getting in bootloader is no problem but i get stuck in the "entering recovery...." screen. It does not move, tested it for some hours. I tried updating the recovery (-), trying to flash stock recovery and reflashing custom (-), trying cwm (-).
After I tried cwm i noticed that it didnt overwrite the recovery but i got both. cwm and twrp, but i cannot delete one of them (didn' work before either). I can start TWRP oder CWM on a booted phone, but updating both bugs and I can't enter recovery with these tools too.
Today I wanted to try again on my own, but my phone won't connect on USB. Tried every port on my computer with and without USB-Debugging. I will try on a other computer, but I could not do this until now. Additionaly I want to wait for some ideas of fixing, as I think "my" trys are not going to work suddenly .
Screen started to turn black a few days ago. Dont know why but I think it could be a software issue. but i cannot update (see above ). When i try to turn my screen on it often just turns instantly black. soft keys are enlightend and it does work (more or less). if i success in sliding down the service bar on the top, i can start my alarm clock app and from there use the soft keys to get in other started apps. From there it works most of the time. Sometimes i need a couple of trys, sometimes it just works as its intended without turning black and sometimes i need several minutes to succeed.
Cannot say more as I did to the graphical issues. Just had them once until I started an app (screen worked). could not reproduce this error.
I would prefer a solution without wiping, but if necessary i will ofc.
Thanks in advance for your help, as I am rather helpless right now.
I attached a photo of the bootloader.
Yours Laexxi

[Q] Help - Reflashing not fixing a soft brick

A couple of days ago, while sitting on the dresser, my XT1053 crashed and has not been able to fully boot and stay alive since. It will give the "bootloader unlocked" message, start all of boot animations, get to the blue-green one and then crash. To get a reboot, I have to hold the power button for 10 seconds, or it just drains the battery. Every once an awhile, the security screen pops up and it will crash, or I can get in, the launcher and services say they have crashed, then the phone shuts off.
I have an unlocked bootloader, but not rooted and was on 4.4.4 before the crash. I can usually get into the bootloader menu, and to recovery. If it crashes, I usually have to restart and do a hard close to get into the menu.
Fastboot works. I've followed this guide: http://forum.xda-developers.com/showpost.php?p=53228057&postcount=148as well as the order in the .xml file that came with the 4.4.4 rom. Everything comes back "OK"
Is there something else that needs to be re-flashed to get it working?
The strange thing is that even though I have erased userdata and cache etc., on the rare occasions that I get beyond the boot animation, it still seems to have my custom message and the security pin. Is it possible that the cache and user data aren't actually getting erased? How do I check?
Any suggestions would be appreciated!

Need assistance reinstalling twrp

For a while I've been using the nonsense rom (provided on this forum) and it's worked fine. Just the other day however I tried turning on my phone, it would get to the boot screen with the animation of the android bot peeing on the apple logo and it would just play that animation over and over until eventually the phone turns off. I figured I just had to restart, but it was the same issue. After trying to reinstall that same rom, I had the same problem. I then tried different roms and the same issue with those, they would get to their respective boot animations and play them until the phone turns off, never going past the boot screen. The one rom that sort of worked with the cayonogenmod 12.1 rom, but the issue with that is after the boot animation, it appears to be starting the set up for the phone, but prompts me to enter a password, which I have no idea what it is. Doing a bit more research, it seems that there may be a problem with twrp and it not formatting (term?) properly.
As of right now, I've done a factory reset on the phone several times to no avail. I just need help getting this phone to work. I've tried looking at a few places and using adb, but the device wasn't found and I didn't have time to look any further because I'm busy with a project I'm working on and with moving. Some places I've looked said to put the phone into usb debug mode, which I can't do since i can't get past any of the boot screens.
Edit / Solved:
I went into twrp and instead of choosing "wipe data" i went to "format data" and that seemed to fix the problem. Although I did have an issue with the nonsense rom, it got past the boot animation, but then gave an error "unfortunately the process com.android.systemui has stopped". I instead installed the raptor rom and it's working fine.

System UI Stopped Working

Hello All,
This is the second time this is happening to me since the latest update, I do not know what is triggering it but the screen goes black and the "System UI has stopped" keeps popping up and even if i close it nothing happens. I cannot access anything in the phone not even reboot menu I have to force restart it everytime. Laste time i ended up formatting the phone which worked but I lost all my data. Please suggest what to do.
edit - I have also booted it in safe mode and the same error pops up.
EDIT - SOLVED - This page helped a lot (https://www.reddit.com/r/GalaxyS8/comments/737y3j/helpfix_substratum_system_ui_has_stopped_issue/) The bixby method or the samsung find my phone method works.
Same here
Damn it, what samsung it doing!!!!!!!!

Stuck on Welcome screen after factory reset

Hello there,
I've just found my old GT-S5300 from back in the day, and I tried turning it on to eventually use it again.
The issue is that when turning on, I get the usual "Welcome to GT-S5300" screen, and it tells me to "Touch the Android to begin"; when trying to do so, my phone doesn't let me go to the next screen to connect to Google and all the miscellaneous steps that come later. The touch screen does react, I can change the language/type a number in emergency call, the Android flashes when I touch it but it doesn't let me go to the next step.
I have tried factory resetting/wiping cache & data but nothing does it, I keep getting stuck on the same screen.
I even tried flashing a custom ROM and the stock ROM, but it seems my phone can't read the SD card I insert in it, I don't know why (32GB, works on other devices).
I have CWM Recovery installed so whenever I go to Recovery mode I have the CWM Recovery menu which appears.
Before burying it in my closet, my phone was indeed rooted.
Do you have any idea if there is a way to use this phone again? Thank you!
