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.

I usually release the power button on the boot screen first and then the other two buttons

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..

Galaxy Nexus in reboot cycle

Hi
My Galaxy Nexus has just started into a constant reboot cycle. The Google logo comes up and the the multi coloured animation thing like normal and then it goes back to beginning.
I never get to enter my pin or anything.
Has this happened anybody else?
It also gets quite hot after been in reboot phase for 20-30 mins.
Thanks
Brian

Im not sure on exact details other than its as it was when I bought it apart from 4.0.2 is installed
I didnt root it or change radio etc
I was just using it as normal, was going in to check battery level I think
ClockWork isnt installed
If I hold down power button and volume button and go into recovery options reocovery mode doesnt work, restart bootloader doesnt help either
Only other options I have are Start and Power off
When I try and go back into those options again all I get is a screen with green Android and Start > Downloading > Do not turn off target
It can stay in this screen for 5 mins or more and go nowhere
This happened earlier on as well so I just turned it off
I tried the same procedure again and I got the recovery menu again but it still didnt work and then tried it again and I just got the Downloading message again
Not sure if any of that helps, I cant check the kernel version anywhere right now.
Oh and its the GSM release of the Nexus

I choose recovery mode and the phone restarts, Google logo comes up and it then goes to a picture of android robot with a red excamation mark over it
It just stays there on that screen for about 2-3 minutes and then retarts
After restarting it goes through sme sequence as before constantly going from Google Logo to multi coloured animation and then restarts again. At no stage do I get to login screen.
Only other option I get when I hold down power button and volume button is to restart bootloader, start and power off.

the hardest part was getting my laptop to pick up my phone in bootloader mode but my laptop is getting old and on its last legs, the usb ports are dodgy for everything

Just to warn you, there's a good chance it will happen again eventually. A few days ago it happened to me for the second time (completely stock).
I decided this time to root it and install a custom rom seeing as how I'd have to flash stock again anyway. I'm hoping that whatever bug that caused it has been fixed in 4.0.3.

The first time it happened was the 11th Jan, on 4.0.1, and the second time was the 29th Feb, on 4.0.2. And yeh it's GSM.
Yeh exactly, sucks having to install apps again etc. Now I'm rooted I've got a nandroid backup just in case it happens again.

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.

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.

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.

[Q] QHSUSB_DLOAD... uh oh.

ROM: ParanoidAndroid 3.91
Happened after rebooting when attempting to access twrp recovery. Initially the "battery charging" symbol did show up, but after holding power and volume up+down it's now bricked.
So far I've tried holding power while plugged/unplugged and holding power + volume up+down for 20s while plugged into a computer, and using the adb reboot command (even though it doesn't show up in adb devices).
I'm guessing the responses I'm going to get are:
1) You shouldn't have rooted/flashed your tablet
and
2) you should RMA
So yep... realize that's the general consensus for QHSUSB_DLOAD issues but thought maybe the nexus 7 in particular might have a fix. Or I guess I'm just hoping the "it's dead RMA it" solution is outdated now.

Usually that means the bootloader can't be accessed but there was a person earlier who had the problem and was able to recover

This is a corrupted bootloader. Some have tried holding the power button down for 20-30 seconds. You will most likely need a new motherboard if you cannot access fastboot.

Question Pixel 6 Pro won't boot / Pixel Rom recovery

Hello hello,
Someone on another website told me to visit you guys here!
My Problem is as follows:
So around 6 hours ago my Pixel 6 pro decided to just turn itself off. I tried various methods of starting it, pressing different button combinations etc but it is completely unresponsive. I tried charging it for several hours but that also didn't do anything. The screen won't turn on at all.
The only sign of life that I have is when connecting my phone to my PC via USB and pressing all 3 buttons (Power, Volume up and down) then a device called "Pixel Rom Recovery" will pop up for a little bit. It disappears when letting go of the power button or after around 20 seconds. If I keep pressing the buttons it will apear again and do the same thing.
What I basically wanna know is:
Is there a way to still recover my data?
Is there a way for me to save my device?
I got some more or less important stuff on my phone and it would be a shame if it all was gone.
How ****ed am I?
Thank y'all for all your help!

Hi,
If you cannot turn on your phone, it'll be difficult to help you. Pressing other 30 sec power button doesn't run ?
In parallel did you contact the Google pixel support ?
It's not to scare you, but I had the same issue on a old Samsung S8 and it was the motherboard 🫤
Hope it's not the case for you !!

So this is in fact just an undocumented Emergency Download Mode that Google Custom Exynos SoC has natively built into it in case of the rare event of a bad boot loader.
I’ve been doing an extreme amount of research lately about bootROM’s, how they communicate, the Driver rule support for interfacing with the phone while it’s Pixel ROM Recovery. The viewable name for the Exynos USB DownLoading mode.
Can I get you to dm me on Telegram? It might be helpful to have more people. I’ll be glad to help in getting this figured out. It could help a lot of other people who don’t have a Pixel 6 too

I have the same issue after trying to update to 1205. I see the Pixel ROM Recovery and a COM port.

If you cannot enter fastboot mode, no way to recover your phone.

Was there a solution to this? The same thing happened to me. When I get to the bootloader and hit recovery the screen just goes black.
