[Q] Stuck in boot loop after enabling second screen in developer options.

While attempting to get HDMI working, I stupidly enabled second screen in developer options in my aosp ROM, which immediately rebooted the phone. I'm now stuck in a loop whereby the phone boots and then restarts when loading the lock screen (presumably it's enabling the second screen).
Is there a simple way of resetting settings to default or bypassing this during boot? I'm away from home else I'd wipe and recover, so any help would be appreciated.
I'm using teamwin recovery if that's relevant.

Try clearing cache, if that doesn't work restore backup.

I think there is a safe mode, not sure how to activate it.
Also, factory reset is possible.

It can be activated only once the phone is booted afaik.

Thanks chaps,looks like a recovery cache didn't work. Lesson learned!

So you got out of boot loop or what?

Sorry, to clarify clearing cache didn't work. I ended up wiping and recovering.

I know this is an old thread but I think I found a solution.
If you wait until the boot animation is already showing and then hold down the buttons like you were trying to boot into recovery it should boot your phone into safe mode. Then you can go into settings and disable the second screen. It may be different on the one x than on my phone though. I have a note 2. I am just trying to keep anyone else who has this problem from having to wipe their device unnecessarily.

Where can I do that? I can't get into recovery mode. I push "vol down+home+power" and it just says "downloading do not turn off target" Is there another place to factory reset?

Pull the battery and try getting into recovery

I pulled the battery and it still just says "downloading.. do not turn off target" and won't go any further
But the strange thing for the boot loop in the top left corner it says "recovery booting" in blue and then its the android guy for a split second and then it reboots.

Pull the battery, then press volume down + home and power and see if you can get into download mode. Then press volume up and Odin stock tar.

I can get there but it just says "downloading... Do not turn off target!!" I have waiting for about 15 minutes and it doesn't change.

If I do volume up it goes into the boot loop. I was trying to make a backup with twrp and I think my phone is stuck in recovery mode boot loop

This is what you are supposed to see. Hook your phone up to tour computer, load the stock tar in the PDA slot, make sure you see com# ie. com6 and then hit start. It will flash the ROM and reboot your phone.

Pull the battery, insert and factory reset again. Pull battery again and Odin stock tar; pick one of the tars in this thread. The steps and tools needed to start are clear.

Note: the thread was just updated for lollipop; the support posts and help posts are related to the KitKat tars. Original is last of the three. OB7 I'd most likely what you're after unless looking for Xposed framework compatibility which is KitKat only, for now.

Can't boot into Recovery?! [SOLVED]

Right out of the RetailBox (with stockRom) I couldn't reboot into recovery using the "VolumeUp+Home+PowerButton" step...
Even now after installing a custom rom and twrp recovery I can't do the hardbutton action ("VolumeUp+Home+PowerButton") to get into the "recovery"
so whats the hiccup here? someone plz
thx

I just flashed a root... and then downloaded twrp through playstore and always rebooted with Newstart chosing reboot into recovery.... so it was fine till now..
now though, after installing IronRom .zip through twrp, it won't reboot anymore, it is stuck at the "Samsung Galaxy Tab S powered by android" starting screen.
Now I want to simply to the hardbutton reboot into recovery step, since i cant access it otherwise... but it doesn't react.
so whats the hiccup here?
thx

I would also like to know this, I recently installed the PAC-MAN (unofficial) rom and things went weird. I tried to flash official Samsung ROM through Odin, things went well but got stuck in Samsung booting logo (not the one that says powered by Samsung). The logo that comes after the Samsung jingle.

So there is no way to get the HardButton way to work?
(My customRom already has multiple shutdown and restart option... thats how i've been operating.)
But once one is stuck somewhere and can't get to the system level (like boot loop or whatnot) it would be great to enter the recovery anyway... thx

You can enter recovery any time you want, you just need to do it right.
Hold POWER + HOME + VOL DOWN until the screen goes blank then immediately change to VOL UP whilst still holding the other buttons until recovery boots.

Holy Damn... thanks a lot!!!! that was really bugging me. I never found anything apart from just holding home+power+volumeup

I just tried this after trying other button combinations found on the web to try to get it to hard reset but nothing happens with my Tab S...it still stays stuck on the Samsung Galaxy Tab S startup screen. Any suggestions as to why that is?

Just signed in to say thanks for this, but for some reason I had to do it slightly differently. I was on stock 5.0.2 and trying to boot into recovery (Power+Volume UP+Home would start Samsung splash screens and then go black without ever booting into Recovery) so my solution was:
Shutdown Tab S, then hold down Power+Volume DOWN+Home (as though to get into Download mode) and then immediately after pressing that initially, I pressed Volume UP while still holding Power+Home.
Problem solved.

Someone please help me! I downloaded the apk above, chose "Boot into Recovery", gave it root, but it just took me to the "Downloading Do not turn off target!" screen & pressing Home + Power + Volume Down doesn't fix it! I'm using a Galaxy Tab S 10.5 SM-T800, stock Lollipop 5.0.2 and I used the combined TWRP & CF-Auto_root package on XDA to root it. Is all hope lost?

Wow. Thanks! Didn't see that anywhere else...

None of these work for me so...I have a feeling for whatever reason I locked myself out of recovery. Yet to try adb recovery but have little hope.

Not possible, purely pilot error.

Well adb recovery to my surprise and happiness worked! The only thing that worked for me.

I have a tab s that failed an upgrade, I have wiped the cache, and the system but it still will not start up.
Any suggestions?

Stuck on boot animation

Hi,
I unlocked via LG dev my phone yesterday, it worked fine, then installed TWRP and SuperSU. Then I restarted my phone and now I do net get into any bootloader anymore. I can use the Hardware Button combination to get into IMEI display screen, but nothing more. I always get the screen Bootloader unlocked then get into LG Logo animation and that's it.
Nothing more.
Sometimes I can start over and over again and I can get my phone recognized by adb, but it says "unauthorized" or "offline".
What can I do now?
Or is it bricked and cannot be used anymore?
edit: I got it in that state that I am not authorized with adb.
I put my pub key in /data/misc/adb/adb_keys on the SD Card, but it seems that its not working...
bye LG

I can use LG Flash tool until the screen to flash the image, then it gets stuck on 0% on my phone and the connection is failed.
What else can I try?

Use the button combo to get into the factory reset screen. If twrp installed it will not reset but open twrp when going through the reset.

I can only use the combo to get into IMEI Display screen. Then I can get into boot animation screen. I cannot get into TWRP.
I can use lg flash tool 2014 and it will get until the screen on phone is at 0% copying, but it will not go further.
And I can get the phone to be regognized from adb, but it is unauthorized. What can I do that it will be authorized?? Is it possible to do that without being into andoir OS?

Do you have tried this exactly?
The only valid and always working and supported way on getting with a hardware key combo(!) into twrp is using the factory reset screen.
Any other key combo like vol up + power depends on the kernel of the ROM! So it may work or not. Factory reset will work always.
For this you have to ensure that you have the latest twrp version really installed(!) because if twrp sits in recovery it will ignore the factory reset command when going through it.
Power down and pull out the battery. Do not forget to remove any USB cable.
Press power down and hold it down. Put battery back while keeping vol down pressed. Press power button and keep now both buttons pressed. When you see the LG logo the first time just release the power button for 1 second ( do not release vol down ) and then press power again and keep both pressed until you see the factory reset screen.
Once you see that screen just go through the steps like you would do a factory reset. If twrp is installed you will just open twrp without wiping any data. Again it is mandatory to have twrp installed otherwise it would really reset your device.

It is still the same problem. I can use the LG Flash tool, but it won't start the flash. It is stuck at 0% and the Flashing Tool says that the connection to server is failed.
I can still go into the reset menu, but it will do nothing.

Nokia 6.1 (TA-1054) stuck in boot loop

Hello.
I did a factory reset on the phone and it went normally but then at "set up as new" option, after booting up, started crashing and saying that setup has stopped working or something like that. I tried to access recovery menu to do a factory reset from there by pressing volume up and power buttons but instead of going to recovery menu, it's been stuck on "Powered by android" ever since. Can't even turn off the device and nothing seems to work. It's stuck.
PLEASE HELP!
