Booting to recovery with button combination not working

So, after trying out a few firmwares (JM2, JG8, JM5) and kernels (Samset&OC) I can't no longer boot to recovery with Vol UP + Home + power. I can't really say when this problem first occurred, but maybe with JG8 flash. The strange thing is that I can get to recovery with adb reboot recovery and through android console with reboot recovery (when rooted ofc). Also download mode works great.
Things I have tried:
-flash again to JM2 and JM5 with re-partition checked (512 PIT)
-cleared cache+data through recovery
-factory reset through phone code (this also cleared the internal SD)
-took out the battery multiple times
-booted phone without sim
-flashed phone without sim
-changed CSC with phone code
-restore a nandroid backup of JM2. Recovery worked with this one when I took the backup
-there's no external flash card inserted
Soooo..does anyone have any idea about this kind of problem?

i had a similar problem after trying few ROMs. In my case, when i pres the key combi i get the boot logo and then few seconds later the screen goes black and then i see the boot logo again, and this goes forever. and then i tried pressing the same key combination simultaneously and once i see the boot logo i let go the power button and keep the vol up and home pressed, and then only it went into the recovery mode.
hope it works the same for you
Cheers

Agreed, 99.9% chance you are doing it wrong.

mmthabet: I had the exact same experience. Letting go of the power button when the logo appears lets me enter recovery.

or you may need to take out the battery first for a few seconds... after that, you can reinsert it back and try recovery mode...
at least this work for me...

Thanks for replies but none of the solutions work. The recovery mode button combination DID work for a few weeks, but then just stopped working.
I know that I'm doing it right. I have always pressed vol up and home down until the phone loaded recovery and only briefly pressed power button just at the start. I have also tried to remove battery multiple times and once waited 30 mins before re-inserting it.
Trust me, I'm not doing it wrong :s And recovery is working great through adb reboot recovery and shell.

More so a timing issue. Buttons not pressed at the same time.
I get it all the time for all combo's.
Just keep trying.

You might already have this however just in case you dont, check out Quick Boot.

With this app you can boot into recovery mode. Have to be rooted though.

this wont work, if you bricked the phone in a bad flash situation.
in times when this app works, you can easily do adb reboot recover
so this app still doesn't address the real issue of how to get the 3 buttons press hardware recovery mode

I release the buttons right when the first Samsung texts comes on the screen. It will take it to Recovery mode. I also had a "boot loop" few times, if I keep pressing the buttons all the time.
Have you tried release your fingers right in the first texts? I really don`t know what is exactly the right way to press the buttons, but this always have took it to Recovery.

Looks like my latest full wipe with *2767*3855# cured it. Flashed JM5-->full wipe-->samset1.9b-->samset kernel and now it works. It must've got stuck somehow in my previous JM5 installation.

I cant get into the download- or recovery-mode by using these keys... so i am not able to flash a new firmware! can anybody help me please? is there a chance to get into the download mode by using an adb-command?

yes
adb reboot download
but it is dangerous, as you can not recover from a bricked state, if your flash is not compatible or if something went wrong with odin, etc.

I you're bricked and can't get into Download or recovery mode, leave the device to boot, it will just show a black screen for a while then will turn its self off, once this happens you should be able to use the key combo.

Any idea how long you waited? Been waiting 5 minutes, hasn't shut off. Mine's a Bell though so I'm guessing I won't have any luck.

The way i do it (no chance of doing it wrong and timing):
hold down+home and then also press the power button for a little more then 10 seconds (so all 3 buttons for 10 seconds). The phone will reset into download mode, never fails in whatever mode the phone originaly was..

Downloading...do not turn off target.

Hey guys I really need help here. I have no clue how but my phone into some weird mode displaying the message in the title. I have a stock Nexus and didn't try to flash or anything like that.
I tried everything on the internet but nothing seems like its working. I am a real noob and need any advice. Is there a way to get the phone back to normal without having to unlock it, root or something like that?

you most likely turned it on without realizing that your fingers are on the volume down and power at the same time. try pulling the battery and turn on the phone again

You put your phone into download mode somehow.
At least, if your title is what your talking about.....then yea, your in download mode.
If you didn't flash anything....try just pulling the battery and restarting the phone.

I tried that. Nothing is working; the phone gets stuck on the google logo and then the logo itself goes and comes back really quickly then the phones turn off. When the phone turns off it takes 10 mins to get it up again!! No clue...
Now the phone won't turn on.

The phone isn't turning on anymore

Is the battery now dead? Will the phone turn on when its plugged in?

I got back to the same screen now, I removed the battery and phone won't even turn off. It's stuck on the same screen even without the battery??? what's going on?
Update: Ok the phone turned off and then I tried to turn it on. It goes to the Google logo and then the screen goes blank.

Can you get to the bootloader?
Vol. Down + vol. Up and power together.
If so then you'll be fine. Just flash a factory image.
There are a few threads that will go through the process in more detail than I am willing to at 6:08am!

Is there a way to take my photos and contact from the phone while it's in the downloading mode or any other way before I flash it. Or am I screwed? I don't have my stuff synced with google+

If the phone doesnt completely reboots to android, I dont think you can get your photo's.
Can you still get in fastboot mode?

my phone is doing the same thing, the downloading screen. I am totally stock, and i can easily turn my phone on and off except i wanna get into bootloader to flash CWM recovery and i cant do so because this screen is popping up.

Are you able to boot into the OS? Or it's only giving you download mode no matter what?

Do you have adb set up if yes adb reboot boot loader that will boot you into the boot loader screen

he can if adb is already running on the system. seems to be that he can't.
@op, if you're stuck on download mode, try odin (damn i really hate suggesting it); i was trying to see if heimdall supports our device, have yet to find proof.

Is there a big green outlined arrow box at the top of your screen that says start, and it points to your power button? If so you are just at the Odin screen instead of your boot loader screen. You get here by just holding vol down and power instead of of holding both vol up/down and power which would bring you to the bootlloader. Also your phone obviously needs to be off before doing either of these. If in fact you are at the Odin screen simply push power and your phone will boot.

It sounds like your volume-down button might be stuck in the pressed-down position (or just shorted out). If that is the case, every time you try to turn your phone on, you will see the screen you described. You can try pressing the volume buttons many times to see if you can get the volume-down button unstuck. If you can't, you can replace the buttons fairly cheaply.
Of course, it could be caused by something else entirely, but that's what it seems like to me.

If the vol-down button is stuck, try booting it up with both up and down held. You might be able to get either recovery or bootloader.

Its working fine now. Except when I flash CWM, vis cmd prompt like I usually do, I can only go unto cem right away and then once I boot up into the os and turn the phone off to get into recovery stock recovery comes back.

I just got this S3 and it wont stop rebooting...

Ok So I just bought this att s3 from Craigslist. As soon as I got home it started restarting , it will reboot like after 10 seconds.
It boots as far as the Samsung logo then restarts. Sometimes it goes all they way to att splash screen then reboots.
What I have tried to fix.
1) boot to recovery whipe data and dalvik, but it won't give me enough time to copleate the command before it restarts.
2) boot to download mode but won't stay on enough time to hook it up to my pc the use odin on it.
3)Booted safe mode and the phone booted up all the way then the power menu came up then restarted.
Im out of ideas Do you think the mother board is messed up?
Plzz help thank you for looking and for your help/...

Did you ask if this was rooted before you got it ? So you got the phone home and had done nothing to it before it started rebooting or did you do something and it start ?
I've heard this happen when someone had a wipe for bad and the recovery gets borked but it could be the power button as well. The hard reboot happens after the power button has been pushed for 10 seconds. This could explain the constant reboots/ Mess around with it and see if that helps. I had this happen on a skyrocket and cappy and the button got "unstuck"

It's not really a matter of it not clicking physically on the outside but something sticking under that button.
From your initial post to you stated it not always restarting at the exact same point during the boot up. Tend to make me think physical.
If its not rooted and has stock recovery someone might have rooted it before and then tried to put it back stock and borked it somehow.
Have you tried downloading Odin 3.07 and see if it's recognized ?
Did it boot when you bought it ? Please don't tell me you bought it without seeing it boot up first...

Can't get past CM boot screen.

So tonight I rooted my phone and decided to download CyanogenMod to it. I created a backup of my phones current install, wiped/reformatted, and installed the latest stable release of CyanogenMod from their website (version 10.2.0). I followed the instructions on CyanogenMod's website for installing from recovery since Heimdall isn't supporting right now. Everything went great, said my radio was recent enough, installed with no issues. I go to reboot and I just got the spinning arrow for ages, won't load. Any ideas? Thanks in advance.

Grrr.. and now, when I try to restore my backup, my phone won't boot. It either crashes on the boot screen and turns off, or I get stuck in a "boot loop" where it just reboots over and over and over but never gets past the splash screen. Ideas?

Well, it's good to know I'm not alone I suppose, but this is frustrating - I don't have a backup phone. :/ Going through an alternate method to try and restore my phone to stock settings - stock is way better than no phone. Lol.

If it vibrates and restarts over and over until you remove the battery. It's a bad power button. I had it happen to me. I unsoldered the button off for now. It stays on now i have a touch recovery and use volume to wake and a tile to sleep.

It's only a bad power button when I try to flash CyanogenMod, then. I found a way to revert back to stock and my phone is fine.

That makes no sense. It definitely isn't a bad power button because it works just fine with stock.

Galaxy A50 no longer booting.

Good evening All, It's been a long time since I last posted but want to start at custom roms again and I'm hoping someone can help me as I am now considering giving up on this device.
My sister-in-law gave me her old Galaxy A50 after it stopped working, gives the circle with lightning icon but not the normal charge notification. If it boots I just get the Samsung A50 start screen but no boot and no boot animation.
I have cleared cache, factory reset and tried flashing stock roms via Odin as the bootloader is currently locked so no custom ROM's for me to play with yet. I have tried a couple of stock roms but no joy.
The questions I have are below:
1, could a faulty battery cause the phone to not boot?
2, Is there a way to unlock the bootloader via ADB or some other alternative?
3, is there anything I've missed that I could try to get it to boot thus allowing me to perform number 2 from within Android?
Thanks all in advance. :good:

Maybe
No
Try flashing through ordin and see if it gives an error or completes, failing that - try flashing TWRP and see if you can boot into that maybe formatting data or wiping the system somewhere else might help?
Have you tried more than one charger / plug? - same thing? maybe bad wire / plug

I had this issue today and last week. there's a bug w the latest firmwares. havent had this issue on april/may builds.
Anyway my solution is.....
Once plugged in (lightning circle shows up and nothing happens)
press volume down + power till it reboots
once it reboots, boot into recovery by quickly holding vol up + power then release it 2 sec after u see galaxy logo
once in recovery. let it charge for about an hour so it should have enough juice to power on
The thing I notice is the phone does not like to have it's battery drained it this happens most of the time, but this started happening on the last few updates only.
So I will rolllback or install the one ui rom with custom kernel to stop it from happening ever again. it's annoying
hope it helps. it works for my end with the similar locked BL and stuff as u have

Thanks for the reply, I have tried a few different images via Odin but non of them work and I get stuck at the same place. I can't flash TWRP because the bootloader is locked, unless you know a way I can do it with a locked bootloader?

Thanks for your reply, unfortunately it still wont boot. It has charge as unplugged and currently sot on the android recovery screen. If you can think of anything else I could try I would be very grateful

You could try again with recovery mode, as it charges with that mode. I had to repeat the steps I took for a couple of times for it to boot. Or use another cable perhaps? that's what I did too. It's really frustrating.
