[Q] Phone will not boot, nor enter recovery mode HELP!

Was attempting to switch back to stock messaging app, and was using some old rom (mint jelly) with Titanium backup/rooted. I made the following changes :
unfreeze messaging app
restart bluetooth pairings
uninstall beauty face
uninstall best face
and then restarted my phone, and will not come back on? What the hell?
Will not enter recovery, at all. Just stays frozen on SAMSUNG. Not amused, please help if you can

Are you sure you are pressing the correct buttons? Volume UP + Power, when the device vibrates release the Power button and when 'Recovery Booting...' blue text appears release Volume UP button.
If you still can't enter the recovery mode there is only one option left: flash stock firmware with Odin!

however there doesnt look like much i can do with recovery mode. the only backup is a year old and might as well be reflashing. is there some way to get into safe mode and maybe undo the changes i made in TitBackup?

To start Safe Mode you have to Power on the device with the Volume DOWN button pressed, until it boots up

Samsung Galaxy S4 I9505 Stuck in Download Mode !!

Hello everyone, I hope you are all fine.
I just brought an S4 2 days ago, and I was forced to Root it using Odin.
The process went well I had my phone rooted and working Fine,Until today when I was listening to music in my phone, and I wanted to turn down the Volume a little bit, but the Volume down button didn't work !!!( it's not a hardware probleme because it was working perfect this morning, but after I gave the phone to my lil sis she had done something in the settings I thinks), so after that I tried to turn off my phone to see if the volume button will work(it was the first time I shut down the phone after the root),and then an error showed up with a yellow triangle on the bottom of the screen, the error message is ''Warning!! A custom OS can cause a critical problems in your phone and installed applications. If you want download a custom os press the volume up key. Overwise, press Down key to cancel. Volume up : continue Volume down cancel ( restart phone) '' . I tried to press both Volume buttons but it didn't work, so I tried to shut it down again and press volume up buton +home+ power button then the phone turned on with the Samsung galaxy S4 screen I was so happy but when it did turn on it was On safe mode -_- , right now I can't flash the room because I can't press the Volum Up button to Continue to Download mode, Right now I'm still at safe mode and waiting for your ideas , Please help me guys I'm new in this Forum a friend of mine told me to post here and they will help you.So please help me.

So you're no longer stuck in download mode but are in safe mode. Power off the S4 and turn it back on. If safe mode reappears then your volume down button is stuck. [EDIT] If you cannot enter download mode, your volume up button is stuck. Exchange the S4 for another unit if possible. If not possible, whack the left edge gently against a table to try and unstick the button. If that doesn't work the button on the motherboard needs to be replaced.

Galaxy S4 i9500 Bootloop without Recovery Mode

Hi,
The problem I have is really very common to most Samsung Galaxy users, but I haven't found any solution to my particular problem. Well, basically my Samsung Galaxy won't get out of bootloop. It just won't go beyond Samsung Galaxy SIV I9500 screen. The phone never did this before this. The phone did, however, rebooted occasionally by itself when running normally.
My phone is rooted, but it runs the official version of Lollipop for Galaxy S4. I had to factory reset my phone one day, and I decided it to reset from the Recovery Mode. After successfully resetting the phone, it booted as usual. Soon after it suddenly turned off, and went into this complete bootloop and would not stop until I remove the battery. Whenever I insert the battery back in, the phone starts by itself, without me pressing any button, and goes in the bootloop again. I can only enter the Download Mode that too for a couple of seconds. When entering the download mode I don't have to press the power button.
Is there any solution to this? I am assuming that my power button suddenly failed. The power button is definitely not stuck. I have opened the entire phone and cleaned the motherboard, and rechecked, it still showed the same problem.
Really appreciate any kind of help.

Hardware issue. Lightly tap the side of the S4 against a table and see if that temporarily frees up the button. Regardless of the end result, you'll need to replace the power button.

Hi,
No need power button to boot in recovery.
Just hold Home+Volume up should do the trick.

@Yoanf_26: How do you expect the phone to get into recovery without turning it on? Volume up and Power are all that's needed to get into recovery. It's the Home button that is optional.

Try a different battery (ask a friend or something if possible). I had similar issues on an i9100 lately. It could only boot to download/recovery mode and was even producing write errors. Looked like brickbug first but was bad battery indeed. It starts slowly with weird behavior and you think you've just messed the rom and just need to reset but it gets worse and worse until you're stuck with download mode only. If you have a spare battery in range its worth a try for sure.

Hello.
I already to start my S4 without power button must just with Volume up and home.
I test with Volume up with power, and my S4 start to recovery.
Differents methods are good to start to recovery. May not for all S4

Guess what? You have a faulty power button, because being able to start the device in any mode without the power button is simply not possible. I tried it just now. Also, if Samsung themselves require the power button to enter recovery or download mode it's illogical to not need it on what is (broadly) the same device.

My power button is good. I test with a custom recovery.
May be not possible with stock. I don't test with stock.

I'm not running stock anything on my I9505. TWRP 2.8.7.0 and CM 12.1 Optimized (currently) installed here. To access Download Mode requires Volume - and Power (Home optional). Accessing Recovery requires Volume + and Power (Home optional, again). Safe Mode requires pressing Volume - and Power, and holding down Volume - throughout the boot process.
As you can see, all functions require power. The fact yours doesn't is not normal.

Maybe, but my S4 is good.

If you think so, who am I to try and persuade you otherwise? When you do encounter an issue with that button, just think back to this thread rather than making a post about it. That way we can both avoid the inevitable "I told you so" that will come out of my mouth.

stuck on android screen and volume rocker not working cant boot into recovery

Hi all,
I hope I am posting in the correct place.
I got my screen fixed by a guy and he returned the phone with the volume buttons not working.
He told me to do a factory reset but I forgot I had a custom Rom installed(extrestolite) so after factory reset the phone is stuck on android screen and I can't use the volume button to boot into recovery. When I connect the phone to my laptop it doesn't show up as an adb device because its not fully booting I presume. So I can't adb shell into recovery either. Do I have any other options here or has my stupidity and this guys incompetent work doomed my phone? Thanks guys.

Did the volume keys work before the screen repair?
If yes, I'd open the phone again and see if it is a simple fix

Yes the functionality of the phone was perfect before the screen fix. I went to a shop and the guy said the volume buttons are soldered to the motherboard(replacing or reconnecting the buttons was my first thought) is this true?

Can you boot into download mode and flash the stock rom with the microSD hack?

Can't get into recovery to save my life!

Guys, I'm wanting to get into recovery mode to wipe my Dalvik cache but for the life of me I can't get to it. I'm doing up+power+home and I go to screen saying 'Downloading do not restart target'. I guess this is download mode. How do I turn this off?
For kicks I tried down+power+home and it asks me if I want to enter download mode. Also tried up+down+power+home but this just does a normal boot.
I know this is probably something really basic but I just can't get in. I did have KingRoot installed a while back. Could this have caused the problem? Any help is greatly GREATLY appreciated. Thanks!

Hold power and volume down, then press volume up when the OS warning screen appears = download mode.
Hold power and volume up = recovery.
Don't bother with the home button. You don't need it. Should the key combinations not work correctly, you may have bad buttons on the motherboard.

Thanks for the quick reply. I double-checked my volume buttons and they work as they should (up = louder; down = softer). I tried power + up and still get the download mode screen. I even tried adb to boot into recovery and it brings me to that same 'Downloading do not restart target' screen.

Prior to writing my post above I tested my S4 to make sure I was giving correct information. Both key sequences worked on my S4.
The only thing I can think of is that you have a hardware issue with your volume down button. To test, try pressing and holding power without touching a volume button. If you enter OS warning mode without pressing a volume button, then your volume down button is worn out and needs to be replaced.
My reasoning is this.
Button failures are the most common issue with the Galaxy S4.
You instantly enter download mode by pressing power and volume up while being unable to enter recovery at all. This means you're skipping a step in accessing download mode, which wouldn't happen if all the buttons were working correctly.

Maybe, but shouldn't my phone go into recovery when I send the command to enter recovery from adb? It just reboots and goes to downloading. My buttons work fine when using the phone when android is up so I'm doubting that it is a hardware issue.

It should, but something is interfering with that. I'd go back to stock using Odin, simply to ensure all parts of the firmware match. Then see if you can get into the stock recovery with the key combo. If you are able to, then you can restore TWRP and flash a custom ROM. Otherwise the device needs to be looked at.

Thanks for the reply. I'm running the stock os without root. All I really want to do is wipe Dalvik cache. Can I do that from adb?

Yep.
