Hi,
I'm new to xda, I was on CM10.1 nightly build 29th Dec, and I was just checking the dev options to see what was what. When I changed
the 'Simulate Secondary Display' settings the phone just froze. It's perfectly fine, everythings there, it's just that when I boot it, it shows the boot logo and when its about to show the home screen it freezes. I know its not bricked, and I know all I have to do is change the Dev Options. Could
someone plz tell me how? I actually have important messages and pictures that I don't want to lose.
Thanks in advance

Flash a different rom like stock based custom rom and install cm10.1 again if you want to
Thankfully I had a fairly recent Titanium Backup so I only lost a small amount of data + time. I hope you manage to find a solution as you said you have important messages and all.
Wiping cache doesn't help. I'm still stuck. :crying:
--- Edited ---
My itchy hand touch that setting as well. Stuck at CM10.1 boot screen.
Solution: Just boot into recovery, wipe cache and reboot. Done and everything working as usual.
Same question
I wiped cache and davkit cache in recovery but no luck
I would like to know the function of this option

1. use Safe mode. (I just pressed all button except power button, and it booted.)
2. disable Simulate Secondary Display.
3. reboot
(side effect : all widgets will be disappeared)

wow, it works, thank u so much! and for the first time I realise that android has a safe mode just like my windows ! feel shame for my poor knowledge
I couldn't enter safe mode. Presing Vol up+ Vol down should enter safe mode?

Yes. I just found this thread because i also locked my S2 activating "second display" and looked for a way to boot up in safe mode.
1. Turn off your phone by long pressing the Power button.
2. Press Up/Down Volume buttons (yes, both) and Power button at the same time.
3. Keep pressing all 3 buttons until boot-up image appears.
4. Release Power button while still pressing volume buttons (not sure if this is mandatory, but worked on my phone)
5. Phone will boot-up with "Safe-mode" badge in the lower-left corner of your screen.
Now go to Settings-Developer options and disable Second Display. After that, just reboot and you should be fine.

confirmed dirty flash does NOT work
confirmed flash 10.1 nonofficial then re flash DOES work
anybody try a restore?? seemed to work for me except i only had an ancient one... plus the safe mode trick seems better unless you just made a backup
im on rezound infected 2.2 JB 4.2.2 by the way and safe mode didn't seem to work but i just read the part where you hold volume buttons after letting go of the power button. so that might work for rezounds still

Seems not to work on HTC Desire Z. In a 3 seconds after holding volume buttons and power button, LED lights up in green and remains in this state. Using Jelly Baby 1.5.0.
Any other way?
EDIT: I found one. Turn on the phone and when on HTC logo, hold S button on QWERTY keyboard until home screen show up.

different phone, different method. the above applies to i9100.
glad you found a way for your HTC.
I wasn't able to boot into safe mode for some reason (HTC Evo with non-stock ROM). My solution was to use adb to edit the settings sqlite database.
Here is the guide I found: blog.jbit.net/2013/01/android-settings-reset-using-adb.html
Simply, I flashed the xposed framework for my device (which I know works as I have done so before.) However, I may have pressed the wrong power off selection in the TWRP menu. Now, my phone boots however, at the point the lockscreen etc. should show, I jus get a black screen.
As far as I'm aware, all I need to do is power off the phone and power it back on again. However, the phone has a unremoveable battery. I do NOT want to reboot the phone (that is holding the power button / power button and volume as neither of these have an effect other than a reboot into the same problem.)
Thank you to any help!
HELP! Blue Wave 8 33GT tablet stuck in recovery mode with "No command" message
I got my Blue Wave 8 33GT (not HD+) tablet completely bricked. First of all, I know this is not really a popular device and some of you might not have a single knowledge about this one, but I hope in any way you might help me get this device working again. Thank you in advance!
Some info about this device:
Bluewave's website: Wave 8
Android OS version: 4.4 KitKat
Device processor: Rockchip-based (RK31)
What just happened? It suddenly reboots while I'm playing and gone into recovery mode with an Android and a "No command." message. Now it won't boot the system anymore whenever I reboot, it always going into this recovery mode.
It has no volume buttons, just a reset, a hard back button and power button. Holding down the power and back button goes into the recovery mode directly. Through normal boot, it flashes the Bluewave logo twice then goes into the recovery. While the reset button immediately turn the device off. There's nothing else I can think of that I can do in this case.
My laptop can recognize it as an ADB Device in recovery mode and I think I may be able to flash it via Rockchip BatchTool, but the instructions I've read states that the device should be up and with a USB debugging enabled which I am not currently able to do in recovery mode. Device is rooted and working totally fine until this happened.
Anyone got into this kind of problem and able to go through it? Please, any help is greatly appreciated.
P.S
Just let me know if there are any additional info I could give you.

Hey! Thanks for your reply and time.
I tried every combination of either of the two keys but there is no such recovery menu showing up, and I am pretty sure that this device doesn't have a built-in recovery for factory reset.
If only I could go to its download mode stuff to be able to flash the firmware...

"Long press the power button to restart the device. If restarting fails, hard reset the tablet by poking the Reset hole using a pin. " it is from FAQ
maybe this could help.
1. Press the power button to get the option menu for
Power off
Reboot
Silence phone option.
2. on that menu you have to hold down that power off option on your touch screen while also holding down the home push button on the side of your tablet.
3. This brings up a screen to reboot into safe mode..(these are the 3 steps the company does not tell you that is why no one gets it to work.
4. HIt yes for safe mode and then hold down your power and home buttons on side of tablet till the dopo Logo appears.
5. Release both buttons and hit the power button one time and then hold only the home button down till a menu option appears.
6. Use the home button to move down to factory reset and press the power button to select. Once it says complete then use the power button to select reboot.
Problem solved. Hope this will help everyone out.
The only way is to remove the battery, attached again the battery then power it on their is no hard reset on blue wave the go to settings factory reset
I received the phone from a friend that can't remember the lock screen password.
I need to wipe the phone, but it will not go to recovery nor fastboot by any method described in this forum.
Anyone has any idea what can be done?
Thank you
No one has any ideas?
Maybe you already tried, but it's worth noting: in order to get to download mode or recovery you should first press the combination of keys (vol+&power or vol-&power) and when when the lg logo appears you should immediately release the power button and press it again. It might not be easy the first times you try.

I obviously tried it.
The logo appears twice, I assume the first time is from the boot section and the second time from the actual application ROM. I tried releasing the power button and re-press it in the first time the logo appears and tried also on the second time the logo appears. It didn't work.
Is the release duration very strict? I released the button for about 0.5 second to 1 second. also I released the button less than 0.5-1 seconds from the appearance of the logo.
You should be as quick as possible, as soon as the logo appears the first time, release and immediately press it again and keep it pressed. If you try and it doesn't work, disconnect the battery before trying again.
I believe you tried everything, but still I can't find any other reason why the phone should boot to Android but not to recovery, apart maybe having both of the volume buttons broken.

I don't see any reaction to the volume keys in the lock screen, so they might be broken.
I was trying to take a screenshot on my Galaxy S3 on stock firmware (4.3) by pressing power + home, but then the screen went black and then all of a sudden the torch flashed, and then it booted. However, I ended up in safe mode. I tried rebooting but I was still in safe mode. I tried factory reset but still, safe mode. I decided to install a custom ROM in TWRP, so I installed LineageOS 16, but it booted into safe mode in that too. I've tried opening the device to see if the volume buttons are fine (which they were) but I still get safe mode. I've tried removing the battery for three minutes and putting it in again but that doesn't work either. What happens each time is I turn on, the flashlight comes on for a few seconds, then it turns off, then the device continues booting and then it says "safe mode" at the bottom of the screen. If anybody could help me on this, it would be much appreciated. Thanks.
UPDATE: I've discovered something else, when the torch flashes on when I power on the device, if I press the volume down button the torch goes off, but when I release it, the torch comes on again. Could this be related to the problem?
yes i think so it is a hardware problem mainly the volume down button is pressed (forced pressed)
