[Q] Developer options black screen - Galaxy S II Q&A, Help & Troubleshooting

Hi,
first sorry for my bad English. I have Galaxy SII with CM10.3 stable (Android 4.2.2), Dorimax kernel based on Siyah. I was played with developer options, because i find there something like 4x and some words, which worked like antialiasing and games looked much more. Next to this option is something like "Sec. display resolution" and i was clicked on HD 1270x720 (it was on default), phone rebooted quickly and Galaxy S2 pop up, then Dorimax kernel logo, CyanogenMod boot animation, phone starts but display is black, only buttons is shining, when i click on that. Phone is 15 sec black, then iam able to see my lock screen for about 1 second and restart... Please, i have in phone many aplications, data and many other things that i need to recover... Iam able to go to CWM, download... But i dont know, how to get it work. Maybe emergency mode will can help me, i was in that mode by mistake, it could help me. Any solutions how to enable emergency mod or how to fix it? Or, if its easy, shall i found some flashable zip, which will turn developer options off? Thanks and ALL REGARDS... U are my last hope.

[Q] My Tab 10.1 Screen doesn't respond

Hello everyone !
Sorry for my bad english
I just bough my Galaxy Tab 10.1 , and after about 5 hours been using it , the Screen doesn't respond anymore , i already Re-start the Tab and also try a recovery to Swipe all my data back to Zero , but no luck , My tab stuck on the main screen and can't unlock the Main menu , can someone help me Please ?
Thank You In Advance .
Press and hold Power + Volume Down until you see the Robot.
Release the buttons immediately you the Robot, then press Volume Down to move the flashing cursor to CWM mode (box with arrow).
Press Volume Up to select the mode and do a complete wipe.
Hello yqed and thank for your help .
I already did that and still have the issue , stuck on the Main Screen and cannot go foward , No respond at all , but i can feel the vibration , but do you have another solution ?
Thanks !
What do you mean Main Screen... can you swipe the circle, or you have a PIN setup and cannot enter it because the tablet does not respond?
Did you do anything to the tablet, ROM install through Odin, rooting, TouchWiz update, etc?
Hi !
Yes , i cannot Swipe the circle , i didn't do anything in particular before the issue , but flash the Tab to see if it's gonna solve the problem with the Stock Rom [ EUR ] , from this -> Thread <- , but no luck till now , the rotation working also .
You have this issue. This was my reply. I know is not funny for you but, I laughed when I saw the video... I hope you did not dropped the tablet into your toiled bowl.
Anyways, this is a good place to look for the issue. Did you played with the kernel or rooted the tablet? Or it was a bone stock when this occurred... Did you updated to TouchWiz using Kies?
Hi !
No , i didn't do anything to the Tab , just left it for about 30 min , when i came back the Screen doesn't respond anymore , i already saw the Youtube videos , i guess the only solution is to send back My Tablet , Thank for your help

The information you have supplied cannot help anyone to offer any useful advise. You will need to specify the number of cores, that is, single, dual or more; screen resolution. You will need to try Micromax A110 ROMs or Lava Iris 501. Good luck.
here is another information about the phone form cpu z app..I really hope some one will give advise how to fix the problem
SOLVED
problem solved..it's a hardware/touch screen error solution change touchsreen and good again :angel::angel:

[Q] Galaxy S2 GT-I9100 hard bricked

Hi guys, I`m new to this forum and I wouldn`t be posting this topic if I found a solution on other forums. If anyone had a problem like mine, or saw a thread before, I would appreciate if you pasted a link to the solution, or gave some kind of advice.
First of all, I`m new to rooting, custom roms, etc., so I guess that whatever I did, it was my fault. I got this Galaxy S2 (GT-I9100) as a gift, and since i already had a phone, I wanted to take a risk and take a shot at installing a lollipop rom. I watched a few tutorials, it seemed simple enough, so i thought why the hell not, but in the process something went wrong...
Sooo... here is what I`ve done:
1.) Rooted my phone with VROOT
2.) Flashed custom recovery with ODIN. I`m not sure which version of CWM it was, 6.0.4.5 I think (the file is named CWM KitKar compatible-I9100). When I flashed CWM, my phone didn`t boot up. All I got was a Samsung Galaxy logo and a yellow triangle for a few seconds before my screen went black again, but I could still access both recovery mode and download mode using the combination of keys.
3.) And then I did what I think screwed up my phone. I thought maybe flashing a lollipop rom through recovery would solve the issue (maybe the recovery is incopatible with my older stock rom and it`s the reason why my phone isn`t booting). So i flashed CM12 from galaxys2root.com. It`s called CM12.1S ROM for Galaxy S2 GT-I9100 (Andorid 5.1)
Not only it didn`t solve my problem, I still can`t get my phone to boot (now I get a samsung logo and a yellow triangle, but screen doesn`t go black after a few seconds, I left it in this state till the battery ran out and still nothing). And on the top of all things, I can`t get my phone to recovery mode anymore, all I get is the yellow triangle. I can still get it into download mode, but it doesn`t connect with my PC anymore. It charges, but I can`t connect it with ODIN anymore. And the weirdest thing is, when I connect it to PC, my other USB port goes crazy and disconnect my USB Wi-Fi adapter
What went wrong? Any advice is highly anticipated. :good:
