[GUIDE] [SAFE MODE] Enter safe mode on stock roms - G2 General

This is an extremely simple guide for those who are not familiar with the opportunity of going into safe mode. Safe mode disables all your third party apps and prevents them from doing anything on your device. You can install and remove new apps, but you can't open any. This is also helpful to determine whether your battery genuinely is bad, or if it is an app or two who are the culprits.
To enter safe mode:
Press and hold the power button until the 'Phone options' menu pop up.
This gives you three main options - power off, restart or turn airplane mode on.
To enter safe mode you have to press and hold 'power off' for about 3 seconds. It will then ask you whether you want to boot into safe mode or not. (Tested on D802).
On some device models, you have to tap and hold 'reboot device' in order to get that option.
It works flawlessly and in order to turn it off, you just reboot your device. During safe mode, the phone can be used as usual, with the exception of 3rd party apps.
Hope this helps!

Or, from the phone turned off, press power until the LG logo appears, release power and press the volume up button + volume down until the phone boot. You'll boot in safe mode
(tested in d80220D)

Thanks for guide

Safe mode?

Did anyone know that our phone had a safe mode to them?
The only real safe mode is keeping it in the drawer and not touching it...
This is for the Galaxy S
If you run in to problems, you may want to try to boot the phone into Safe Mode so you can undo whatever was done to cause the problem.
1. Power the phone off.
2. Turn the phone back on while pressing and holding the Menu button.
3. Keep holding the Menu button until the Home screen loads. The lower-left corner should say Safe Mode.
Once you’ve removed the offending app, you’ll want to boot normally. To do so, pull the battery from the device, then replace it. The next time you start the phone, it should no longer be in Safe Mode.
FYI I have never had to do this.........
Hope that helps,

Can't get into download mode via button combination

My issue is as stated as above. I presume my phone has this feature disabled, making this phone near useless for me.
Tried having phone completely off and holding down volume down + home + power like in the videos, to no avail.
I've come from a Galaxy 3 which automatically started up download mode during the boot sequence.
Is there a way to root my phone without Odin or enter download mode with another method? Can't use "reboot download" in terminal as it's not rooted.
I haven't found any topics quite like my issue here. My phone is a international Galaxy III with label being exactly I9300. Any help is appreciated.
You could buy usb jig that will sort it iv never heard of this issue ever

Interesting, atleast there's something to fall back on if there are no other solutions.
Postage to New Zealand would be horrendous.
Please confirm it doesn't work in the following order.
- Make sure you have no case on the phone.
- Power off the phone
- Unplug it from the charger
- Remove the battery for 30 seconds
- Press and hold Volume-Down and center hardware button.
Make sure both buttons are proplery pressed, and the center button is pressed in the middle.
- Press the power button, and release it when the logo appears. Keep the other 2 buttons pressed
- Wait for it to boot
If it doesn't work, try repeating 2 times starting at the top.
If it still doesn't work something is faulty. Check if all the buttons work as expected.
Thank you very much d4fseeker, the battery out was the crucial thing I was doing wrong.
It shouldn't be necessary (and usually isn't) but I've seen on multiple occasions that Samsung phones sometimes don't react to the Download mode or Recovery mode when normally powered down.

Mega Download Mode

I have a Galaxy Mega GT-I9205, which I have rooted and installed CWM recovery. I have had enormous problems in getting this phone into download mode with the stated key sequence of pressing Volume down, Home and Power simultaneously. It does work but probably only once in 40 tries, the other 39 times it just starts up normally and then has to be shut down before you can try again
I managed to find a different way to do this that works nearly every time and thought I would share it with you in case anyone else has the same problem, this is what you do.
Get your usb lead and plug it into your charger or a live usb socket on a computer. Plug the micro usb end into the phone and then without delay hold down the home and volume down buttons. Do not touch the power button. Keep these two buttons held down until the download mode warning screen appears (do not be tempted to let the buttons go when the phone vibrates to tell you it is connected to a power source or the method will fail). When you get the warning screen use the volume up button to confirm as per usual.
A couple of things I should say, there is absolutely nothing wrong with any of the buttons on my phone, they work perfectly in normal use, and secondly, I am not really a 'power user' when it comes to phones, I am more at home with computers, so this may be old news to you, but I have never read it before.
Hope this helps someone.
You could just install this Quick Boot (Reboot)
I also fail sometimes. Hold down vol down and home. Then press power and hold the three buttons until I see download mode. If I loosen any of the three keys too early, it may fail.
Download mode is Vol Down and Power only not the Home button as well.
Press both until the phone powers down and then you can release the power button but keep the Vol Down pressed until you see the warning screen.
And Recovery Mode is Power + Vol up (no home).
When we see a little blue line on top, pull up from Power but continue press the Vol up until Recovery arrive.

Click to expand...
Click to collapse
Whit "Quick Boot" we can go directly to Download Mode or to Recovery Mode. (no more Power + Vol xx)
Thanks for the replies. I discovered Quick Boot for myself, only today! It is certainly the best answer.
Sorry for not replying earlier, I subscribed to the thread, but got no notifications of replies, don't know why.
BTW Troute is absolutely right, Download mode is just power+Volume Down.
I got the 'home' key as well info from here: Edit Can't post outside links due forum rules, never mind.
Also
Code:
adb reboot bootloader
works as well (if you have adb on your computer).
Found a.convenient way to go into recovery or download mode a while ago:
Recovery : long press power button , select restart , confirm, put a finger near volume button, as soon as the phone vibrates, press vol up until booting recovery line shows up. The pressing must be quick and immediately after the vibration.
Download mode is the same as as above, only in the place of press vol up, do press vol down once and need not hold. Download mode shows immediately.
You can use Wanam Exposed module which has function of Power submenu. Tick Enable 4 way reboot menu option.
Can someone tell if triangle away works for Samsung Galaxy Mega 5.8 GT-I9152 or not ??

thelightphone 2 - fastboot/safe mode

Just got my lp2 and it's a neat little minimal android device. The farthest I've gotten is not very far, but I can post here in case anyone's looking.
lp2, software v48 (48-release), firmware 4101.0.A.0070
fastboot:
you can enter fast boot by "hard rebooting": hold the lock and tool button simultaneously for 20-30 seconds, the phone should vibrate, then the screen will flash and it will show the "go light" screen, then turn off. Hold the power button again to turn it on, but hold the vol down button. It should stay on the "go light" screen. If it's plugged into your computer usb,
Code:
fastboot devices
should now list it. I also found it in usb info as having manufacturer "Google", while in the normal mode it has manufacturer "Android".
Code:
fastboot oem unlock
does not work.
To resume normal booting, press the lock button again.
safe mode:
if you reboot and hold down the ringer up + ringer down keys, it'll boot the phone into "safe mode". I'm not yet sure how safe mode is different from normal mode, other than there will be faint text at the bottom right of the screen saying "Safe mode". Rebooting will return it to the "normal" mode.
Has anyone else gotten any further? It's running a nonstandard base for android, so developer mode doesn't seem accessible from the menus. I'd like to at least get adb shell on this thing, but my endgoal is sideloading apps.

[HOWTO] Force a reboot in TWRP

So the dog tried to eat the phone, thus the bottom part of the screen is dead so there are no software buttons to use.
Now where the problem comes in.
You go into TWRP to see if you can make a more resent backup but you can't see enough due to the strips on the screen and since the software buttons are gone you're stuck and it will lock itself and you can't even swipe to unlock. Since newer phones don't allow the battery to be pulled you're stuck until you run it down which will take days.
TWRP and any other recoveries should reboot when the power button is held down IMHO but obviously they don't. Few things are more annoying than something electrical that you can't turn off.
I found that if you hold down the volume up and volume down buttons then press and hold the power button it will force a reboot.
Forced power off is holding power down and power button: https://www.verizon.com/support/knowledge-base-215164/
This is also provided as a popup instruction when you first boot the phone after setup. So, there is a way to force it off, just not with a single button as you might prefer.
You may have found another option with the reboot process.
I can confirm this procedure worked on my Redmi Note 4 (MTK) stuck in TWRP after I executed "/sbin/recovery" from adb shell, which killed the touchscreen and USB connectivity (??). The standard way (volume down + power) did not work, but this volume up + down + power worked, strangely enough.
