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..

[Q] Can't seem to enter recovery mode.

Hi, I'm trying to flash Clockworkmod using this method.
http://forum.xda-developers.com/showthread.php?t=1446593&highlight=clockworkmod+recovery&page=10
But now I don't seem to be able to get it to go into recovery mode at all any more.
I hold down up home and pwer and it gets to the screen with the picture of the android and the box with the arrow coming out of it. But then it just seems to reboot.
The phone still works other than that.
Is there a knack to getting it into recovery mode thaqt I just haven't got?

Ok I've managed to get it into recovery (but only once- there's clearly a knack to it I'm missing)
But the problem now is that it's still the stock recovery.
My phone is rooted and debugging is on.
any ideas (on either)

u use adb to flash? if that didnt work y not try to flash using odin v4.43?

I seem to have the same problem, did you figure out how to go in recovery without getting reboot right after you press the menu button?
EDIT: I might have been pressing buttons in the wrong order or too long/short. As soon as I see samsung logo I released power button and I holded menu button a bit longer. I'm not sure about the last one tried again with a short press and it worked as well, I think the most important thing here is when to release power button.

is it using odin method?

Did my friend brick his nexus?

Well a friend of mine got a new nexus couple of weeks ago. He's pretty much an android newbie so he didn't root it, it was SimFree so he just used the system update and got JB 4.1.2 (I think was the version) over the stock ICS. Well today the phone out of the blue just got to rebooting on its own, and now it never boots. It gets to the animated X logo after the Google logo and that's it. I did try booting it up vit vol- + pwr btn pressed and it got into ODIN MODE where it says
Start
Downloading...
do not turn off target!!!
I have no idea what ODIN mode is, since I only had a couple of HTC's,huaweis etc.
Is this ODIN mode the recovery? Is there anything I can do with the phone? Hard reset or something like that?
thx

No, it's not bricked. When you hold both vol buttons + power that's the bootloader. Also just flash it back to stock via fastboot.

If u can get to download mode u should be safe. Work from there. Should fined everything u need in Nexus Forum.

How can I do that?From Odin mode or from the bootloader? I got into bootloader and there's the Start ,restart bootloader,recovery mode,and power off options. I tried getting to recovery mode but it also wont start.
I installed a bunch of roms on motorola cliq,a ton of htcs,a couple of huaweis all from cwm but this ODIN mode is something new for me.I have no idea what it's for

[Q] Need Help - SM T705 stuck on start up screen.

Greetings XDA Developers,
Newbie here. I own a Samsung Galaxy Tab S (SM T705). I was able to root it a few weeks ago and I decided to install a custom recovery (TWRP) using an app from the Playstore named "TWRP Manager". I didn't hesitate to do so using this method because I was able to install TWRP on my GT I9300 successfully from the past using this app. However, after being prompted by the app that the recovery was successfully installed and needs to reboot the device, my tab was stuck on start up screen ( See attached photo ). I tried long pressing the power button but nothing happened. I waited until the device ran out of battery and when it did, I plugged in the charger and I'm back at the same screen. After google-ing some possible solutions, I tried to boot it into recovery but was unsuccessful, however, I was able to boot into download mode.
I'd like to ask for the help of some "experienced" users in this forum on how to solve this problem. And if possible, I'm hoping that flashing a stock recovery using Odin wouldn't be my last resort.
Thank you in advance.

Your going to need some fast hands for this one! I've ran into this lots of times when testing kernels and such. Any force reboot by holding Power Button+ Home Button + BOTH Volume buttons all at the same time. Press and hold that combo until the screen goes black. Then once the screen goes black quickly press and hold Power Button+ Home Button + Volume down buttons all at the same time. You should no enter into download mode. You said that you drained the battery so I would suggest charging it in download mode for 30 minutes or so then flash TWRP with Odin.
Your going to need to flash stock recovery or TWRP with Odin to override the boot and get it working
The TWRP app doesn't always work in which is why I use Odin.

As a side note for future reference, hard reset is simply hold POWER + VOL DOWN.
As said all you need do is boot to download mode and flash recovery.
If you're on lollipop you may need to immediately boot into recovery after flashing to make it stick.

Hey, thanks for the heads up. But how exactly do I "immediately boot into recovery after flashing to make it stick." Since after I flash recovery via odin, it would obviously automatically reboot my device? sorry for the dumb question.

Both are the same I think. Some people name it by our product name or device name (one has xx and one doesn't. Both are the same)

You either be quick and hold POWER + HOME + VOL UP as soon as it reboots or you uncheck auto reboot in Odin then restart manually.

So did the solution work? I am looking at a SM-T705 on ebay being sold for parts with similar symptoms. hoping I can fix it for a great bargain.

Recovery-mode only, is there any hope?

[SOLVED] Download mode can't be removed, I had to try all dat long but I finally could boot into it.
Hi,
So... I had a working Samsung Galaxy S9 (SM-G960F/DS) running Lineage OS yesterday. I noticed something wrong related to the mobile network in my country (FR) and decided to flash the correct stock firmware matching the country code XEF before doing a full LOS reinstall.
Fast-forward 20hrs of download, I perform the flash operation this morning using heimdall(1) and reboot.
Now, the phone bootloops. I can't get into download mode as usual, and the only thing that is available is the stock recovery mode that allows:
apply update from adb
apply update from sdcard
wipe data
wipe cache
mount /system
view logs
run graphics test
I have a working all-countries firmware archive that contains the one that was working previously (minus the mobile network problem). But since I don't have download-mode anymore I can't install it. I tried adb sideload (which is available via the "apply update from adb" option), wipe data/cache to no avail.
Is that hard-brick? Did you ever experience a similar situation? I think there's no way out of this but any advice would be appreciated.
Thanks again!

You should be able to get into Download Mode (Vol Down & Bixby & Power)
Keep trying, try keeping hold of the button combo until after the phone reboots twice hopefully the second time into download mode
Download mode has nothing to do with firmware or recovery that has been flashed, and if you can enter recovery mode, it doesn't sound like a hardware problem either
And use a Windows machine & ODIN 3.13.1 to flash stock

Unfortunately it doesn't seem to work, i tried many tiimes and I usually can do that very easily. It seems flashing the corrupted images wiped it out.

Impossible as it is not part of the firmware, nor can be touched by firmware, it is part of the hardware (Think BIOS vs OS)
You can even 100% wipe all internal storage clean so there is no OS at all and download mode will still work fine
Keep trying

Okay I guess it's possible that the download mode is still there but I can't reach it.
I've been trying hundreds of times every combination I can think of (including Home + Vol Down + Power that used to work).
Any alternative way to trigger the download mode ?

How are you trying Home? There is no physical home button
The button combo is Vol Down & Bixby & Power from a powered off state
Keep a hold of all 3 until it hits the Warning screen, then hit Vol Up to enter Download mode
No other way to access it that I know of, USB Jig hasn't worked since a few models back
Have you tried factory resetting from inside recovery? Unless you used CSC during the stock firmware flash, that could be a reason for the bootloop

Maybe the issue is with the Volume Down button, does it work inside of recovery for navigating the menu ?
What happens when you try entering Download mode? It just tries to boot as if you didn't press anything?
Only other thing is to hold Volume Down & Bixby, then connect the USB cable to power it on (instead of using the power button)

The volume down button works perfectly in the recovery menu.
When I try entering download mode normally while device is powered down, the phone never turns on.
When I try to hold the buttons during the interval of the boot loop, it goes to recovery (yes, even with volume down, not volume up).
The other technique you mentioned also went to recovery.

BINGO! I kept trying. Did this all day literally hundreds of times.
And it just worked.
I didn't change the way I do it, I think there was some nasty timing going on with the boot loop.
Anyways... lesson learnt: download mode is indeed hardcoded. What a day!
Thanks for being so helpful!
